Ottawa's small business scene runs on QuickBooks logins and monthly reconciliations as much as it does on good ideas, and finding a bookkeeper who actually answers the phone in tax season matters. This list was put together from public web sources, Google and directory reviews, and each firm's own site, looking for real businesses with a track record of serving Ottawa clients. It is not exhaustive, and it leans toward firms with visible, verifiable reviews.
1. Better Books Canada
Area: Downtown Ottawa (116 Albert Street) · Specialty: Bookkeeping and tax for startups, entrepreneurs, and law firms
Better Books Canada is run out of a downtown Ottawa office and has built a reputation around founder Bashar Qawas, a former CRA employee whose clients repeatedly describe him as responsive and thorough. Reviewers on ProvenExpert and the company's own testimonials page single out how he explains the process in plain language rather than accounting jargon. It suits early-stage founders who want a bookkeeper who can also talk them through a CRA notice.
2. Numetrica
Area: Ottawa-wide, cloud-based · Specialty: Cloud accounting, bookkeeping, and virtual CFO services · Rating: Over 110 Google reviews (as of August 2025)
Led by Moe Tabesh, Numetrica has crossed 110 Google reviews, a volume that puts it among the more heavily reviewed bookkeeping shops in the city. Clients cite the team's accuracy on GST/HST filings and its comfort with cloud tools like QuickBooks Online. It's a fit for businesses that have outgrown a solo bookkeeper and want CPA-level oversight without hiring in-house.
3. Plug CPA
Area: ByWard Market, Ottawa · Specialty: CPA-led bookkeeping and tax preparation · Rating: 5.0 on Google (21 reviews)
Formerly known as CPA Plus, this ByWard Market firm holds a clean 5.0 rating across 21 Google reviews, with clients describing the tax process as "stress-free" and praising how consistently filings go out on time. It suits small businesses that want their bookkeeping and year-end tax handled by the same CPA-led team rather than split across two providers.
4. Beck Ltd.
Area: Manotick and Ottawa · Specialty: Bookkeeping and accounting for professional corporations and medical practices
Beck Ltd., led by Kelly Beck, operates out of Manotick and serves Ottawa-area professionals, with a particular focus on medical practices and professional corporations. Client testimonials on the firm's site describe the staff as fast, professional, and easy to reach, with more than one reviewer saying they returned the following year. It's a solid pick for incorporated professionals who need bookkeeping bundled with tax planning advice.
5. 2450 Solutions
Area: Ottawa, cloud-based · Specialty: Outsourced cloud accounting and bookkeeping
2450 Solutions positions itself as an outsourced accounting department, and reviews posted on its own site (sourced from Google) describe the team as "reliable, organized, and detail-oriented," with month-end reports landing on time and year-ends often wrapped before clients have even gathered their paperwork. That kind of proactive turnaround suits business owners who would rather not think about their books until the numbers are already done.
6. Accountapotamus
Area: Carleton Place and Ottawa · Specialty: Outsourced bookkeeping, payroll, and QuickBooks training
Accountapotamus has been supporting Ottawa-area small businesses for years, with one long-term client citing five-plus years of service and consistently responsive support. A law firm client specifically praised the team, naming staff members Paula and Janice, for going "above and beyond." It's a good option for service businesses that also want staff trained up on QuickBooks rather than just handed finished reports.
7. Plus Advisors
Area: Ottawa and Eastern Ontario · Specialty: Bookkeeping and Profit First implementation
Plus Advisors pairs standard bookkeeping with the Profit First cash management method, working in QuickBooks Online and Xero. A client of almost a decade described the team as responsive and effective at using technology to save time, and the firm says it maintains client satisfaction above 90 percent. Owners who struggle to keep profit rather than just revenue may get the most out of its approach.
8. Nunniyer Business
Area: Nepean, Ottawa, and Eastern Ontario · Specialty: Bookkeeping, payroll, and tax preparation · Rating: 3.9 (12 reviews) on its Chamber of Commerce listing
Founded by Beth Carhart and Tom Bauld, Nunniyer Business has grown into a multi-office practice with locations in Nepean and Williamsburg. Clients describe the team as being consistently on their side, including flagging accounting changes that could save money rather than waiting to be asked. It suits business owners who want a bookkeeper who doubles as a proactive advisor.
9. SaltyBooks Bookkeeping
Area: Ottawa (Southport Drive), serving Canada and the US · Specialty: Cloud bookkeeping for small businesses and non-profits
SaltyBooks staffs QBO and Xero Certified Advisors and has built part of its client base around non-profit organizations, a niche with its own reporting quirks that not every bookkeeping firm handles well. One reviewer credited founder Saul with rescuing them from a backlog of receipts and unfiled taxes. It's worth a look for non-profits and small operators who need cloud-native bookkeeping without a big-firm price tag.
10. DSB Bookkeeping
Area: Ottawa · Specialty: Small business bookkeeping
DSB Bookkeeping was founded by Darryll Bowes, who brings more than 20 years of experience as a facilities controller and in restaurant financial management before starting the firm. That background shows up in the firm's focus on hands-on, small-business bookkeeping rather than large corporate accounts. It's a fit for restaurant and hospitality operators in particular, given the founder's industry background.
How We Built This List
This list was compiled from public web sources, including company websites, Google reviews, Better Business Bureau listings, and business directories, current as of August 2026. It is not a paid placement, and ottown was not compensated by any business named here. Ratings and review counts are quoted only where a specific number was found in a source read during research; where no verifiable figure existed, that field was left out rather than guessed. This list was last reviewed in August 2026 and will be revisited periodically as ratings and business details change.
Sources: company websites for each firm listed, plus review data surfaced via Google, ProvenExpert, the Better Business Bureau, and the Ottawa Chamber of Commerce directory.
