The many accounting firms in Canada provide a variety of services to businesses and individuals. Accounting firms can help with bookkeeping, tax preparation, auditing, and other financial and consulting needs.

A basic understanding of accounting terms is important for small business owners but for any advanced accounting help it makes sense to outsource this business function to an outside accounting firm.

There are also a number of fintech companies offering accounting software in Canada for small businesses. These accounting platforms help with most basic accounting and bookkeeping needs but are not robust enough for most large businesses or for any complicated accounting services.
