Slide to your monthly transaction volume, add payroll headcount and the filings you want handled — HST, remittances — and get a monthly retainer range with the annual total. The default 150-transaction business with three employees and HST returns runs about $325–595 a month. Catch-up work is priced separately on purpose: clean monthly books are cheaper than an annual shoebox rescue, and most firms price the rescue to make that point.
Volume and complexity: transaction count sets the base, payroll adds per-employee work every cycle, and filings add deadline-driven compliance. That is why a retainer scales with the sliders here rather than being one flat number for every business.
Backlogged books are forensic work — matching months of transactions, hunting missing documents, fixing miscategorizations. The $300–800 one-time range covers typical small backlogs; years of neglect cost more. Once current, the monthly retainer keeps you off that meter permanently.
Bundling QBO or Xero into the retainer ($30–60) usually rides the firm's wholesale pricing and keeps ownership of the file clean. Just confirm you retain access to your own data if you ever change firms — reputable ones put that in writing.
