Accounting Solutions

Ontario bookkeeping services and controller support for small and mid-size businesses — so your books are accurate, your reporting is current, and your finances are never in the way of growth.

Bookkeeping Services for Growing Businesses

Most small and mid-size businesses in Ontario reach a point where their bookkeeping is technically getting done — but nobody is actually owning it. Transactions are recorded, but the books are weeks behind. Reports exist, but they are not trusted. Month-end close is a scramble, and nobody in leadership has the financial background to know whether the numbers are right.

Greysuits solves that with a complete bookkeeping and accounting service built directly into your business. We place a dedicated bookkeeper — supervised by an experienced Controller — inside your operation. Your bookkeeper handles the day-to-day: payables, receivables, payroll, bank reconciliation, and monthly bookkeeping. Your Controller reviews all of it, maintains accuracy, and acts as your internal financial advocate, translating your numbers into decisions your leadership team can act on.

The result is a finance function that runs with the rigour of a much larger company — without the overhead of building one.

Why Businesses Choose GreySuits

Accurate and Compliant Financials

Your books are behind, your numbers aren’t trusted internally, and the thought of an audit makes the room go quiet. We take ownership of the full accounting cycle — transaction recording, government filings, and audit prep — so your financials are always accurate, current, and defensible.

Finance Structure That Grows With You

You’ve outgrown spreadsheets and disconnected tools, but nobody has had the time or expertise to fix it. We implement and configure the right accounting systems, reporting frameworks, and chart of accounts — building a foundation your business can actually scale on.

Insightful Reporting and Forecasting

You’re making major decisions without reliable numbers to back them up. We build and deliver the reports, forecasts, and cash flow models your leadership team needs to plan with confidence and stop flying blind.

Strategic Financial Oversight

You have a bookkeeper but no one asking the harder financial questions. Our Controllers — backed by CFO-level expertise — bring senior financial leadership into your business, guiding growth decisions, supporting due diligence, and ensuring your finances are aligned with where you’re taking the company.

Frequently Asked Questions

What is outsourced bookkeeping?

Outsourced bookkeeping means hiring an external firm to manage your financial records, accounts payable and receivable, payroll, and reporting. GreySuits Advisors provides outsourced bookkeeping to small and mid-size businesses across Toronto and the GTA, supervised by a CPA-credentialed controller.

A bookkeeper records daily financial transactions, manages accounts payable and receivable, processes payroll, and prepares monthly reports. At GreySuits, every bookkeeper is supervised by a CPA controller, ensuring accuracy and strategic oversight beyond what a standalone hire can deliver.

A bookkeeper handles day-to-day transaction recording. A controller oversees the full accounting function, reviews the bookkeeper's work, produces financial reports, and makes data-driven recommendations. GreySuits provides both in a supervised model, meaning every bookkeeping engagement includes controller-level oversight.

Outsourcing eliminates recruitment, training, and turnover risk. It provides immediate CPA-supervised expertise without a full-time salary. For Toronto businesses spending $50,000 to $80,000 on an in-house hire, outsourced bookkeeping through GreySuits delivers equivalent or better quality at a lower monthly cost.

GreySuits assigns a dedicated bookkeeper to manage your accounts on a monthly retainer. A CPA-credentialed controller reviews all work, provides reporting, and acts as your financial advocate. Engagements cover accounts payable, receivables, payroll, government remittances, and monthly close for businesses across Toronto and the GTA.

GreySuits bookkeepers work with QuickBooks Online, Xero, and Sage. If your business is not yet on a cloud accounting platform, we can recommend and implement the right system as part of onboarding, including chart of accounts setup and historical data migration.

GreySuits provides bookkeeping and controller services to businesses in construction and trades, SaaS and technology, healthcare, manufacturing, logistics, and professional services across Toronto and the GTA. Each engagement is staffed by team members with sector-specific financial reporting experience.
