Monthly bookkeeping and tax for the business owner who would rather know than wonder.

Two Canadian CPAs running a digital accounting firm that handles the whole picture, bookkeeping right through to tax, on a monthly basis. So you stay ahead of every deadline and stop carrying the weight of it alone.

Two CPAs.

One mission.

A whole lot of small business owners that finally know their numbers.

WHO YOU’RE WORKING WITH

Not your grandmother’s accountant.

We’re Martina and Ashli, the Chartered Professional Accountants behind Grow CPA. We started this firm in 2019 with one belief: that small business owners deserve more than a once-a-year tax return and a vague answer to every question.

So we built the kind of accounting firm we wished existed. Proactive, not reactive. Holistic, not piecemeal. Digital-first, paperless, and led by real CPAs who pick up the phone when you have a question. From our base in Muskoka, we work with small business owners across Ontario, helping them build their business, their wealth, and their legacy through accounting that actually moves with them.

MEET THE FIRM

THE HONEST TRUTH

You didn’t start your business to spend Sunday nights guessing what you owe in tax.

Most business owners we meet are running a good business that’s been let down by the systems behind it. The bookkeeping is behind. The HST deadline showed up faster than expected. The tax bill landed bigger than promised. And your accountant only calls when something’s already late.

You don’t need another accountant who reviews the year after it’s over. You need one who works alongside you while it’s happening.

A clear path from:

BEHIND → UP TO DATE → IN CONTROL.

THE APPROACH:

  • We start by pulling everything into order. Books cleaned up, anything overdue brought current. No judgement, just a clean baseline to build from.

  • We set up the monthly cadence. Paperless intake, digital checklists, clear deadlines, and a single home for every number that matters. You stop chasing paper. We stop chasing you.

  • Every month, your books are done, your filings are prepared, and your tax position is known long before it’s due. We send the reminders. We send the checklists. You spend Sunday with your family.

  • Reach out when you need us. Questions on a lease, a hire, a new revenue stream, incorporating from a sole proprietorship. We’re here all year, not just at tax time, with answers you can actually use.

WHO THIS IS FOR

Established business owners who want more from their accountant.

Most of the businesses we work with are based in Muskoka and across Ontario.

They’ve been in business five years or more, or they’ve spent a career in their field before going out on their own. They run service-based companies, trades, professional services, and creative businesses. They’re women. They’re men. Some are solo operators. Others lead teams of five, ten, or twenty. Team size doesn’t determine fit.

What they share is the same instinct. They’re humble enough to know they aren’t the expert on their own numbers, and they’d rather invest in getting it right than try to save by getting it wrong.

THE KIND OF WORK THAT EARNS THE KIND OF WORDS THAT FOLLOW.

  • "Working with Grow CPA has taken a lot of the accounting and tax side of the business off our plate."

    “They’ve helped us put the right systems in place, keep our bookkeeping and CRA filings up to date, and provide regular reporting with clear explanations of what the numbers are telling us. 

    We have current financial information we can understand and rely on, which makes it much easier to make informed decisions and focus on running and growing the business.”

    Luke Howell & Stu Young, Rally Electric Inc.

  • "Grow CPA has been a great partner to our organization. They’ve helped make our financial reporting and compliance requirements more manageable and have given us greater confidence in the financial information we rely on to make decisions."

    “What I appreciate most is their responsiveness, practical approach and understanding of the non-profit environment. 

    I would tell another non-profit that Grow CPA feels like an extension of your team. They are accessible, supportive and there when you need them.”

    Suzanne Willett, Community Living Huntsville

  • "As a small business owner, having Grow CPA take care of my bookkeeping and accounting has been such a relief!"

    “Martina and Ashli take so much off my plate and give me back valuable time to focus on what I do best and what I love most about running my business. They’re always happy to answer my questions, no matter how big or small, and make everything feel so much easier. They’re knowledgeable, approachable, and genuinely great to work with. 

    I also love knowing I’m supporting another local, women-owned business. I highly recommend Grow CPA!”

    Leigh Diggles, Comfort Bakeshop

  • “Working with Grow CPA has been one of the best decisions we’ve made for our business."

    “Martina’s expertise and guidance have helped us streamline our bookkeeping, payroll, and tax preparation, alleviating so much stress and allowing us to refocus our energy on the parts of the business we’re most passionate about. We truly can’t imagine running our company without their assistance and highly recommend Grow CPA to any business owner looking to take their business to the next level.”

  • "We have had an excellent experience working with Grow CPA. They are incredibly easy to work with—friendly, responsive, professional, and always willing to help. They provide valuable insights into our agency’s financials, helping us better understand our numbers and make informed decisions."

    “Their work is consistently excellent, thorough, and completed in a timely manner. We also really appreciate their strong communication and the innovative technology they use to make working together seamless and efficient. The customized checklists are a particular favourite—they help keep everything organized and ensure we know exactly what is needed.

    Most importantly, Grow CPA is genuinely a joy to work with. Their expertise, professionalism, and approachable nature make what can sometimes feel like a complicated area of business much easier to navigate. We would highly recommend Grow CPA to any organization looking for knowledgeable, responsive, and forward-thinking accounting professionals.”

    Brad Horne & Carly Barnes, Community Living Parry Sound

  • "Ashli is very patient, approachable, and available to answer questions at any time. She works to find solutions and is willing to meet in person or via Zoom at Board meetings. We find it very informative to have Grow prepare our monthly financial reports, along with a video and explanation of the results."

    “Grow CPA is in tune with our business and provides suggestions for saving funds and identifying areas where additional funding could be applied. They work alongside other agencies to complete reports, including audits, required by the government. They are very knowledgeable about government reporting, HST, and annual charity tax returns.

    I would highly recommend Grow CPA for your financial needs.”

    Heather Conwath, Huntsville Co-operative Nursery School

  • "They were kind, non-judgmental, and knowledgeable, which gave me the confidence I needed."

    “Being a small business owner is not easy. Not only are you responsible for your job, but all the behind-the-scenes work that is necessary to make things run smoothly. It was clear early on that I was going to need to outsource my accounting.

    Enter Grow. By far the best business decision I have ever made.”

    Alyssa Rowley, A.R. Editing Company

  • “Entrusting Grow CPA with my business's accounting was a no-brainer from the first call I had with them."

    “Knowledgeable, warm, efficient, and professional are just a few of the words I'd use to describe this firm and the feeling of ease they give me. They have alleviated a massive burden of work off my shoulders, and their virtual processes save me time and energy.”
