How Professional Bookkeeping Saves Small Businesses

In today’s fast-paced business climate, keeping accurate books isn’t just bureaucratic overhead – it’s a lifeline. Small and medium-sized businesses in Montreal (and beyond) face complex tax rules, frequent changes in regulations, and the ever-present risk of audits from Revenue Québec or the Canada Revenue Agency (CRA). Yet many entrepreneurs delay hiring a bookkeeper, thinking they can “handle it at tax time” or save money by doing it themselves. The reality is that in 2025, every small business needs a professional bookkeeper to stay compliant, financially healthy, and poised for growth. In fact, poor bookkeeping is often at the root of costly tax errors and missed opportunities. A skilled bookkeeper not only records numbers but helps protect your company from mistakes that could trigger audits or penalties, while giving you the insight to make smarter decisions.

Small businesses are the backbone of Montreal’s economy, and they deserve the same level of financial diligence as any top corporation. In this guide, we’ll explore why bookkeeping is essential in 2025 and how it can be a game-changer for your business. We’ll also show why combining a bookkeeper’s day-to-day expertise with CPA oversight (like Mackisen’s all-in-one CPA-led services) is the gold standard – akin to having both a great cook and a master chef in your financial kitchen. Let’s dive in.

Why Businesses Need a Bookkeeper

Every small business owner knows they should keep good records – but what are the concrete benefits of hiring a bookkeeper? Early on, it’s crucial to understand why this role is so vital. Below are key reasons every business needs a dedicated bookkeeper (especially in Quebec and Canada’s regulatory environment):

Always Audit-Ready (CRA & Revenue Québec)

A bookkeeper ensures your financial records are complete, organized, and backed by documentation, so you’re prepared if the tax man comes knocking. Both Revenue Québec and the CRA expect a “clean trail” of invoices, receipts, bank statements, and journal entries to verify your filings. If an expense isn’t documented, an auditor will simply disallow it – in other words, if it isn’t documented, it never happened. Businesses that fail to maintain proper books can face penalties, denied tax credits, or multi-year audits. In short, good bookkeeping is your first line of defense against audits. (Ask yourself: Would your business be ready if the CRA or Revenue Québec audited you tomorrow?) Maintaining thorough records is not just best practice, it’s the law – for example, the Canada Business Corporations Act requires companies to retain accounting records for at least six yearslaws-lois.justice.gc.ca, and failing to comply can result in fines up to $5,000.

Avoiding GST/QST Errors & Penalties

Sales tax compliance in Quebec can be tricky – charging the right GST/QST, claiming input tax credits (ITCs), and filing on time. Mistakes in GST/QST reporting are a top trigger for audits. For example, incorrectly claiming tax credits on exempt or personal expenses, or mismatching your reported sales between GST/QST returns and income tax returns, will raise red flags. A knowledgeable bookkeeper will correctly track taxable vs. exempt sales, ensure GST/QST collected equals what’s remitted, and keep all supporting documents. This avoids nasty surprises like reassessments or interest on unpaid tax. Remember, Revenue Québec legally requires businesses to keep all GST/QST records for at least six years (same as CRA), and missing records alone can lead to denied refunds or penaltiescanada.ca. By having a bookkeeper stay on top of sales taxes, you minimize errors and dramatically reduce your audit risk in this area.

Corporate and Personal Tax Protection

Proper bookkeeping protects not only your company’s tax filings but also you as an owner. How so? In Canada, if a corporation neglects its tax obligations, directors can be held personally liable for certain unpaid taxes like GST/HST and payroll source deductions. This means sloppy books or missed filings can put your personal assets at risk under federal and provincial laws. Both the Canada Business Corporations Act (CBCA) and Quebec’s Business Corporations Act mandate that companies maintain adequate accounting records for at least six years (and as noted, failing to do so is actually an offense). A diligent bookkeeper helps you comply with these record-keeping laws and ensures things like payroll remittances, GST/QST collections, and income tax installments are properly recorded and paid on time. This shields you and your fellow directors from legal liability by preventing the kinds of errors that lead to personal liability notices. In short, good bookkeeping is not just about avoiding mistakes – it’s about protecting your business and the people behind it.

Compliance with Quebec/Canada Regulations

Beyond taxes, there are other compliance areas a bookkeeper covers. For instance, Quebec’s corporate laws and Canada’s federal acts require accurate records of your finances, official meeting minutes, shareholder contributions, etc. A bookkeeper helps maintain these corporate records systematically as part of the “minute book” of the company. They’ll also make sure you have the supporting documents needed under various laws – from Quebec’s Taxation Act to the federal Income Tax Act – to substantiate all your claims. In essence, you’re bulletproofing your business against fines and lawsuits by having everything in order. And if you ever need to provide records (to a bank, an investor, or a government agency), you can do so quickly and confidently. Many grants and loan programs, for example, will ask for financial statements and proof of expenses – with a bookkeeper’s work, you’ll have those ready without a scramble.

Stronger Finance & Audit Trail

When every transaction is recorded with proper receipts and correctly categorized, you create a robust audit trail. This means if anyone (be it your own CPA, an auditor, or a potential buyer of your business) examines your books, they can trace any number back to its source. Such transparency builds trust and credibility. It also forces discipline: for example, you’ll be far less likely to mix personal and business funds (a big no-no) when a bookkeeper is reconciling accounts and asking for receipts each month. Ultimately, consistent bookkeeping keeps you honest, accurate, and in control of your finances – no guessing where the money went. A great bookkeeper gives you peace of mind. As one accounting firm aptly put it, a bookkeeper “ensures compliance with tax laws and deadlines” and prepares financial reports to inform business decisions. They track your money and help you protect it.

Next, let’s explore how preventing mistakes in your books can save you from audits and fines.

The Key Role of a Bookkeeper: Preventing Tax, Audit, and Compliance Errors

Every year, countless small businesses get hit with unexpected tax bills, audits, or government notices – often due to avoidable bookkeeping mistakes. Here’s the truth: many CRA reviews and audits are triggered not by random chance, but by inconsistencies and errors in filings. A skilled bookkeeper acts as a sentry, catching and correcting those issues before your numbers go to the government or other external parties. Let’s break down some common problems a bookkeeper helps you avoid:

Missing Documentation & Receipts

As mentioned, claiming expenses without proper receipts is asking for trouble. The CRA operates on the principle that if an expense isn’t supported by documentation, it will be denied. In a CRA audit manual, auditors are instructed to “disallow the expense unless there is other satisfactory evidence to support the amount claimed” if the proper receipt or invoice isn’t there. A bookkeeper will implement systems (often digital apps) to record all your receipts and invoices as you get them. No more shoeboxes of faded receipts! This habit ensures that come tax time or audit time, you can defend every deduction. It’s such a simple thing, but it’s arguably the #1 bookkeeping mistake entrepreneurs make – and it’s easy to fix with the right help. By maintaining a clear paper trail (or digital trail), your bookkeeper keeps your deductions safe and your tax filings accurate.

Avoiding “Oops” in Sales Tax

GST/HST and QST are among the most technical areas of bookkeeping. It’s not just about math; it’s about classification and timing. If you accidentally claim input tax credits on expenses that aren’t actually eligible (say, on client meals beyond the 50% limit, or on a purchase used personally), you could face a reassessment. Or if your total sales on your GST/QST returns don’t match the revenue on your corporate income tax return, the CRA will notice the discrepancy. These kinds of mistakes are top audit triggers. A bookkeeper prevents them by reconciling your sales tax returns with your books each reporting period. They know what should be taxable vs. exempt, and they make sure all those numbers align. Given that Revenue Québec and CRA auditors love to target inconsistent GST/QST filings, having a bookkeeper double-check this is invaluable. It keeps you in the tax authorities’ good books – literally.

Proper Classification of Accounts (GIFI codes, etc.)

One often overlooked area is how financial data is categorized for tax return purposes. In Canada, corporate tax returns use the General Index of Financial Information (GIFI) codes to classify items on your financial statements. If accounts are misclassified – for example, if income or expenses are lumped into the wrong categories – it can confuse the CRA’s systems or even trigger a manual review. Wrong or missing GIFI codes can make your return hard to read and raise questions. An experienced bookkeeper, especially one under a CPA’s guidance, will ensure your accounts are mapped correctly to the right GIFI codes before year-end. This means your T2 corporate tax return is clear, compliant, and less likely to be questioned. It’s a technical fix that can save a lot of headaches down the line (think of it like spelling and grammar for your financial statements – your bookkeeper makes sure everything is in the right place). The result is a return that sails through assessment without red flags.

Preventing Payroll and Remittance Mistakes

If you have employees (even just yourself on payroll), there are numerous filings to handle – payroll source deductions, T4/RL-1 slips, CNESST premiums, etc. A bookkeeper will help run your payroll or work with payroll software to ensure deductions are calculated and remitted on schedule. One common error is when the total wages on your income statement don’t match the T4 slips filed with the CRA (for example, a bonus was expensed in the books but not actually processed through payroll). That discrepancy can trigger a CRA query, since the agency cross-references corporate tax returns with payroll filings. A bookkeeper with proper checks in place makes sure payroll entries are done right and cross-checked. They’ll reconcile payroll records to the penny, so that government filings (which are matched by CRA computers) are consistent. This protects you from penalties for missed withholdings and ensures your team members get the proper tax forms. In short, no nasty surprises with year-end T4 reporting or payroll audits.

Routine Bank Reconciliations (No Surprises)

Ever scramble at year-end to figure out why your books don’t match your bank account? That’s usually because reconciliations weren’t done regularly. A bookkeeper reconciles your bank and credit card statements every single month, catching issues early. This has two big benefits: (1) It spots errors or missing entries (for instance, a bank fee or client payment you forgot to record), and (2) it prevents the need for massive, round-number adjusting entries at year-end which scream “I didn’t do my books for 12 months.” In fact, the CRA will flag accounts that show large, round-number journal entries at year-end to “true up” the books, as this suggests a lack of consistent record-keeping. By reconciling regularly, your bookkeeper ensures the books are clean and consistent throughout the year. This level of diligence truly is “the foundation of audit defense for a CRA review” – it shows that you run a tight ship and that your records can be trusted.

In sum, a professional bookkeeper acts as quality control for your financial data. They catch typos, miscodes, omissions, and oddities before those turn into larger problems. Many tax errors that lead to fines or lost money – like missed deductions, double-counted income, or sloppy records that can’t support your claims – can be directly traced to not having a competent bookkeeper on the job.

Example: Imagine trying to file your corporate taxes when your records are a mess. Perhaps you discover that your “office supplies” expense is inexplicably high because personal grocery bills got mixed in, or you realize you never recorded some cash sales from last summer. These scenarios are not fantasy – they happen to busy entrepreneurs all the time! The result? Either you overpay taxes (by missing legitimate expenses) or you file an incorrect return that might get flagged. A bookkeeper’s job is to prevent these situations by maintaining accurate, separate, and well-supported records year-round.

Finally, consider the stress reduction: when you know your books are accurate and up-to-date, you sleep better at night. If an audit notice ever arrives, you won’t panic; you’ll be confident everything is in order. And if you need quick financial info (say, for a loan application or a strategic decision), you have it at your fingertips, thanks to timely bookkeeping.

Bottom line: A good bookkeeper doesn’t just crunch numbers – they protect your business from costly mistakes. As the saying goes, “an ounce of prevention is worth a pound of cure,” and bookkeeping is the prevention that saves you from very expensive cures later on.

Bookkeeping as a Business Growth Tool: Monitoring Trends, Securing Loans, Managing Expenses

Up to now, we’ve focused on compliance and avoiding pitfalls. But bookkeeping isn’t only about playing defense – it’s also an offensive weapon for growing your business. High-quality bookkeeping provides you with accurate, timely financial data, which is gold for making strategic decisions. Here’s how a bookkeeper can be one of your best business growth tools:

  1. Financial Visibility & Trend Monitoring: Ever make decisions “flying blind” because you don’t have a clear picture of your finances? With regular bookkeeping, that problem disappears. Your bookkeeper will produce monthly financial statements (income statement, balance sheet, cash flow) that show exactly how your business is doing. By reviewing these reports, you can spot trends early: Are sales rising or plateauing? Did a certain expense spike last month? What’s your cash flow trend over the past 6 months? Armed with this info, you can respond proactively – perhaps ramp up marketing if sales are dipping, or cut a costly supplier contract if expenses are climbing. Consistent bookkeeping effectively gives you a dashboard for your business. Many successful entrepreneurs treat their monthly financial review like a doctor’s check-up for the company’s health. It’s no surprise that companies with up-to-date books are often more agile and resilient; they catch issues and opportunities sooner. As one source noted, “solid bookkeeping shows you mean business – it builds trust, credibility, and peace of mind” for stakeholders and owners alike. It also readies you for bigger moves down the line (like selling the business or attracting investors) because you have the track record to prove your performance.

  2. Securing Loans and Investment: When it comes to getting financing – whether a small business loan, line of credit, or bringing on investors – your books can make or break the deal. Lenders and investors need to see accurate financial statements to evaluate your business. If you approach a bank with disorganized or outdated records, it not only slows down the process, it undermines their confidence in you. In fact, one common reason business loan applications get rejected is incomplete or faulty documentation. Lenders often say that inaccurate or incomplete paperwork can lead to a business loan application being rejected. Don’t let that be you. A bookkeeper will ensure you have clean, loan-ready financial statements at any time. This includes a solid profit & loss statement, balance sheet, and proof of cash flow – all neatly tied out and reconciled. For example, at Mackisen we provide “bank-ready” CPA-reviewed financial packages as part of our CFO advisory services, precisely because we know how much easier it is to secure financing when your numbers are organized and verified. If you ever apply for a loan or mortgage, you can simply hand over the requested reports with confidence. Moreover, having good historical data means you can quickly prepare projections and budgets for lenders or investors. Many entrepreneurs who maintain strong books find they can even negotiate better terms, since banks trust their data (and see that you’re a lower-risk client). The same goes for government grants or R&D tax credits – solid documentation and properly categorized R&D expenses can help you claim incentives without hassle. (Tip: Canada’s SR&ED program, for instance, offers significant tax credits for R&D, but you must have detailed records of those expenses. A bookkeeper can help track your R&D costs separately so you don’t leave that money on the table.)

  3. Expense Management and Cost Control: Ever wonder where all the cash is going? Bookkeeping can illuminate that. By tracking every expense and assigning it to the proper category, a bookkeeper helps you analyze your spending. You might discover, for example, that your software subscriptions have quietly ballooned over the year, or that a particular product line has much higher costs than you realized. With accurate books, you can calculate key ratios like gross margin, profit per product/service, and overhead as a percentage of sales. This is invaluable for identifying cost-saving opportunities. Maybe you’re spending too much on rush shipping, or your utility costs are spiking – these patterns emerge when you compare month-to-month reports. Furthermore, a bookkeeper can help you set up budgets and then produce budget-vs-actual reports to gauge how well you’re controlling costs. Many of our clients use these insights to negotiate better deals with suppliers, cut unnecessary expenses, and ultimately boost their profit margins. Think of it as shining a flashlight on your financial efficiency: nothing hides from a well-kept set of books!

  4. Cash Flow Monitoring: Growth doesn’t just depend on profits on paper – cash flow is king. You can be selling a lot and even turning a profit, but still run into cash crunches if you’re not monitoring receivables, payables, and cash balances closely. A bookkeeper helps by keeping tabs on who owes you money (accounts receivable aging) and whom you owe (accounts payable). They’ll alert you to overdue invoices that you need to chase and help schedule bill payments to optimize cash flow. By reconciling bank accounts and tracking cash movements, they also ensure your reported cash matches actual cash, so you always know your true cash position. If you’re planning to expand or invest, you can consult your up-to-date books to see if you have the liquidity to do so, or if you might need a bridge loan. In short, bookkeeping gives you the visibility to manage your cash proactively, which is absolutely critical for growth. It’s often said that more businesses fail from poor cash flow management than from lack of profits – a good bookkeeper helps make sure you’re not in that statistic.

  5. Faster Decisions and Strategic Planning: When your bookkeeping is current, you don’t have to wait until year-end to know how you did – you know in near real-time. This enables quicker course corrections and strategic moves. For example, if you see by August that a particular service offering is far more profitable than others, you might decide to double down on it for the rest of the year. Or if you notice your accounts receivable are growing too large (customers taking too long to pay), you can tighten credit terms now, not six months later when it might be too late. Essentially, bookkeeping turns your financial data into an ongoing feedback loop for running your business. Without it, you’re driving with eyes closed until the “annual check-up.” With it, you have a constant pulse on your company’s health. Modern bookkeepers often use cloud accounting software that can even show you dashboards of key metrics. With Mackisen’s clients, for instance, we often set up custom KPI dashboards (Key Performance Indicators) so owners can see things like monthly sales, gross margin percentage, or inventory turnover at a glance. This kind of insight is typically what larger companies get from a finance department – but thanks to bookkeeping technology and expertise, small businesses can have the same advantage.

In summary, bookkeeping isn’t just about taxes – it’s about making your business more profitable and easier to manage. By monitoring trends, controlling expenses, and keeping you prepared for opportunities (and challenges), a bookkeeper provides the financial foundation for growth. As your company grows, your bookkeeping will also become more complex (which is a good problem to have). That leads into our next topic: why having a bookkeeper plus CPA oversight is the ideal combination for truly strategic financial management.

Why a Bookkeeper Alone Isn’t Enough: The Value of Mackisen’s All-In-One CPA-Led Services

Imagine a busy restaurant kitchen. The bookkeeper is like the line cook, diligently chopping ingredients and cooking dishes to order. The CPA is like the head chef, overseeing the operation, creating the recipes (strategy), and ensuring every plate meets high standards. Both roles are crucial. If you only have a head chef but no cooks, nothing gets done; if you have cooks but no chef, the quality and direction might suffer. Similarly, a bookkeeper working in tandem with a CPA gives you the best of both worlds – meticulous daily accounting and high-level financial guidance. This is the philosophy behind Mackisen’s all-in-one CPA-led service model.

To be clear, a qualified bookkeeper is immensely valuable on their own. But there are limits to what a standalone bookkeeper (especially if they’re not backed by a broader team) can do. Here are some scenarios where having CPA oversight makes all the difference:

Complex Transactions & Accounting Judgments

Let’s say you receive a government subsidy, or you enter into a complicated lease agreement – how should it be recorded? Bookkeepers might not always know the nuances of revenue recognition or when to capitalize vs. expense an item. A CPA, with their deeper accounting knowledge, can guide those decisions. Another example: misclassification of items in financial statements (like that GIFI code issue we mentioned earlier). A CPA will ensure your financials align with proper accounting standards (ASPE or IFRS) and tax rules, making adjustments as needed. This prevents errors that a bookkeeper might not catch alone. Think of it as quality assurance: the CPA reviews the work to make sure it’s not just done, but done correctly. With CPA oversight, even unusual or complex transactions are handled properly, so your statements are accurate and reliable.

Tax Planning & Compliance Oversight

Bookkeepers are generally not tax experts. They record transactions as they occur, but they might not foresee the tax implications of certain actions. A CPA or tax lawyer on the team can provide that higher-level oversight. For instance, say you’re paying yourself as an owner – should it be taken as salary or dividends (or a mix)? A bookkeeper will process whatever you instruct, but a CPA will advise on the most tax-efficient mix and ensure it’s recorded properly. Or consider sales tax: a bookkeeper can file your GST/QST returns, but a CPA will perform a high-level review to ensure nothing is being missed or misclaimed (especially if you’re in an industry with special rules). By having CPA oversight, you dramatically reduce the chance of significant tax mistakes – such as misreporting income, mishandling asset depreciation, or missing out on credits/deductions – because a professional accountant is looking at the big picture. It’s like having an experienced pilot monitor the flight plan while the co-pilot handles the controls. You get an extra layer of protection and strategic advice when it comes to taxes and compliance.

Audit and Legal Defense

If you do get audited or face a compliance inquiry, a lone bookkeeper might feel out of their depth dealing with CRA agents or the legal nuances of tax law. Mackisen’s model includes CPAs and even tax lawyers and former auditors on the team. This means if an audit letter comes, you have experts who have been through the process ready to step in and handle it. We ensure your books are audit-ready from the start, and if needed, we can represent you or prepare the necessary evidence in a way that a bookkeeper alone might not be equipped to do. It’s a major stress relief knowing that the same firm that did your books can also defend them in front of the authorities (or in court, if it ever came to that). Many small businesses that only employ a bookkeeper end up scrambling to hire a CPA at the last minute during an audit – with Mackisen’s all-in-one service, you’re already covered. We’ve got your back from daily bookkeeping all the way to CRA/ARQ audit support and appeals if required.

Strategic Financial Advice

While bookkeepers focus on the past and present (recording what has happened), a CPA can help you look forward and plan for the future. This includes budgeting, forecasting, business valuation, and financing strategy. For example, should you lease or buy that new equipment? Is your pricing model yielding the margins you need? How can you improve your working capital management? These are questions a seasoned CPA or CFO-level advisor can tackle. At Mackisen, our fractional CFO service gives clients access to “CFO-level” leadership without the full-time cost – meaning you get strategic insight that you likely wouldn’t get from a typical in-house bookkeeper or even a solo accountant. By coordinating bookkeepers with higher-level advisors, we ensure your day-to-day data rolls up into meaningful advice. It’s the synergy of execution and strategy. You have the cooks and the chef collaborating: daily transactions feeding into strategic decisions. The end result is a business that’s not just compliant by the books, but also optimized for growth and profitability.

Now, let’s talk about cost. Understandably, small business owners worry that engaging a full CPA firm sounds expensive compared to “just hiring a bookkeeper.” But consider this: hiring an in-house CPA or controller can cost anywhere from $150,000 to $250,000 per year in salary alone for a seasoned professional. (In fact, CFOs for small companies in Canada often start around the $150K mark.) That’s not feasible for most small businesses. Even a moderately experienced full-time bookkeeper might run $50K–$60K/year in Montreal when you factor in benefits. In contrast, Mackisen’s outsourced model is far more affordable and efficient. You’re essentially sharing the cost of high-level experts with other clients, and you pay only for the services you need, when you need them. Studies show that outsourcing accounting services can be 40–60% cheaper than maintaining an in-house finance staff. By outsourcing to an all-in-one firm, you convert a large fixed cost into a more manageable variable cost.

What do you get for this investment? Comprehensive service. Mackisen provides a team that covers all the bases: daily bookkeeping, payroll processing, tax preparation, financial reporting, and even specialized services like financing support or international tax consulting. Instead of hiring, say, a bookkeeper and separately paying a CPA firm for year-end and a tax lawyer for a reorganization, you get everything under one roof. This not only saves money, but also time and headaches. All your financial data and advice come from one coordinated source, so there’s no disconnect between “who did the books” and “who is doing the tax return” – we do it all together, seamlessly.

Returning to the metaphor: with Mackisen, you have your financial cook and chef working in tandem. The bookkeepers (cooks) ensure the day-to-day transactions are recorded accurately and on time. The CPA/auditors/tax experts (chefs) provide the recipes, seasoning, and final touch – ensuring compliance, offering adjustments, and advising on taste (i.e., financial strategy). The result is a five-star financial operation for your business. You get the benefit of multiple skill sets without the full-time cost of each.

Clients often realize the true value of this combined approach when something unusual happens – for example, a sudden CRA query, a desire to expand internationally, or structuring a deal to buy out a competitor. With a simple bookkeeping service alone, you’d have to seek outside help for those scenarios. With Mackisen, you just call us and our in-house experts (tax lawyers, auditors, CFO advisors) jump in alongside the bookkeeping team who already knows your books intimately. This one-stop convenience can be a game-changer.

In summary, a bookkeeper alone is good; a bookkeeper + CPA team is exceptional. It’s about coverage and quality. We ensure that not only are your books correct, but you’re also getting proactive advice and protection. And as noted, the cost is far less than building your own finance department – the savings can be on the order of 40–60%, all while giving you a higher level of service. This approach is why many of our clients say we’re like an extension of their company – “one firm for everything: bookkeeping, tax, audit, and financing — fast, accurate, results-driven.”

Whether you’re looking at a merger, an acquisition, or just improving profitability, our senior advisors provide the insight you need to make informed decisions.

Financing Support (Loans & Grants)

From preparing the paperwork for a line of credit to navigating the application for a Quebec business grant, we guide you every step of the way. We know exactly what lenders want to see, and we’ll package your financials and business case accordingly (remember those “loan-ready financials” we talked about). Our familiarity with local Montreal lenders and government programs can give you an edge in getting funded faster and on better terms. We essentially make sure nothing in your application raises concerns, increasing your approval chances.

Legal Compliance & Advisory

Through our in-house tax lawyers and strategic legal partnerships, we assist with things like corporate reorganizations, setting up holding companies or family trusts, and ensuring compliance with laws such as Quebec’s Bill 96 (language laws that can affect certain business documents) or other sector-specific regulations. We also offer specialized attestation services and help with things like immigration-related financial documentation (for example, if you need a CPA-certified financial letter for a visa, or an audit report for a government tender, we can provide it). These are niche needs, but our clients appreciate that they don’t have to find a new firm for these services – they can trust the team that already knows their numbers and business intimately.

International & Cross-Border Tax

In an increasingly global economy, many Montreal businesses have dealings in the US or overseas. Our international tax experts make sure you remain compliant with multi-jurisdiction tax rules while optimizing your global tax position. Whether it’s U.S. tax filings for a branch or subsidiary, transfer pricing between related companies, or coordinating with foreign accountants for an overseas venture, we handle the complexity so you can expand without borders (literally!). Expanding to the U.S.? We’ll get your IRS filings in order. Selling to Europe online? We’ll advise on VAT/GST implications. You can grow globally, knowing your local and foreign tax obligations are under control.

In essence, Mackisen is your one-stop financial partner. By having all these services under one roof, we ensure nothing falls through the cracks. Your bookkeeper, accountant, and tax advisor talk to each other daily – because they’re on the same team – which means you get cohesive advice. For example, if you’re considering buying a building for your company, our team will simultaneously evaluate the bookkeeping treatment (recording the asset on the books), the tax angles (capital cost allowance, GST on the purchase, property tax implications), and the financing implications (loan vs mortgage, impact on cash flow). You get a 360° answer, not siloed viewpoints. This holistic approach saves you time and money, and leads to better outcomes.

Your business deserves top-tier financial support. Let Mackisen be the CPA and bookkeeping partner that helps you thrive. Together, we’ll ensure your books are not just in order, but a springboard for your success in 2025 and beyond.

  • An expert bookkeeper backed by CPA oversight keeps your finances clean, compliant, and poised for growth.

  • Staying audit-ready: detailed records and CPA-reviewed books mean you can handle a CRA or Revenue Québec audit with confidence.

Footnote: Small businesses that invest in professional bookkeeping and accounting support often save significantly in the long run – both in money and in peace of mind. From avoiding costly CRA penalties to unlocking better loan terms, the ROI of having the right financial team is well documented. And remember, outsourcing these functions can be far more cost-effective than hiring in-house, often 40–60% cheaper than maintaining an internal accounting staff. With Mackisen’s model, you get that cost efficiency plus a personalized touch from a local Montreal firm that understands the unique Quebec business landscape. It’s truly the best of both worlds – just ask our many clients who’ve experienced the “Mackisen difference.” Here’s to your business’s financial success!

Mackisen refers to Mackisen Global Limited (“MGL”) and its global network of member firms and associated entities collectively constituting the “Mackisen organization.” MGL, alternatively known as “Mackisen Global,” operates as distinct and independent legal entities in conjunction with its member firms and related entities. These entities function autonomously, lacking the legal authority to obligate or bind each other in transactions with third parties. Each MGL member firm and its associated entity assumes exclusive legal accountability for its actions and oversights, explicitly disclaiming any responsibility or liability for other entities within the Mackisen Organization. It is of legal significance to underscore that MGL itself refrains from rendering services to clients.
