Accounting & Bookkeeping Services for Ottawa's Small Businesses
Ottawa, ON – Public/private mix, SaaS, and professional services
Ottawa may be Canada’s capital, but it’s powered by small business hustle. From federal consultants and SaaS startups to nonprofit leaders and side giggers, everyone’s balancing big ideas with CRA deadlines.
But here’s the truth: Even the most ambitious plans stall when your books are out of sync.
At Square Accounting, we offer remote-first, regulation-ready bookkeeping and accounting tailored to Ottawa’s unique blend of work – public, private, and everything in between.
What We Do for Ottawa-Based Businesses
Whether you’re juggling contracts, running a nonprofit, or launching a tech platform, our job is to keep your numbers clear and your structure compliant.
We handle:
- Monthly bookkeeping and cloud-based reconciliation
- GST/HST registration, returns & audit-ready compliance
- CRA-compliant payroll, including T4s, T4As, and ROEs
- T1 and T2 tax filings for freelancers, corporations, and dual-income setups
- Budgeting, grant reporting & cash flow forecasting
- QuickBooks and Xero setup, migration, or full cleanup
We’re structured enough for federal contractors – and flexible enough for your side hustle.


Why Ottawa's Small Businesses Have Unique Accounting Needs
Ottawa isn’t just the seat of government – it’s where public sector meets private drive, and passion projects flourish in every pocket of the city.
That means Ottawa’s accounting needs are complex and nuanced:
- Government contractors need consistent GST practices and audit-proof invoicing
- Nonprofits require transparent reports for funders and boards
- Multilingual teams manage bilingual invoices and dual systems
- Freelancers & consultants often serve clients across provinces - or borders
- Founders with day jobs need clarity without paying enterprise-level fees
At Square Accounting, we specialize in bringing structure to chaos – without slowing you down.
