Bookkeeper Invoice Template Canada — Monthly Services Billing

Self-employed bookkeepers in Canada work with small businesses and entrepreneurs on an ongoing basis, providing services ranging from monthly bank reconciliations to payroll processing, GST/HST filing, and year-end preparation. Billing for these services effectively — with a clear scope, the right tax treatment, and professional invoicing — is essential to running a profitable bookkeeping practice.

This guide covers what bookkeepers typically invoice for, how to structure hourly vs. flat monthly retainer billing, whether HST applies to bookkeeping services, and a complete example for a $1,200/month retainer client.

What Bookkeepers Invoice For

The scope of bookkeeping services varies by client, but common billable items include:

• Monthly bank reconciliation — reconciling bank and credit card statements against the client's accounting records
• Accounts payable and receivable entry — entering vendor bills and client payments
• Payroll processing — calculating and filing payroll, issuing pay stubs, remitting payroll deductions to the CRA
• GST/HST filing — preparing and submitting quarterly or annual returns
• Year-end preparation — preparing the books for the accountant, coding transactions, reconciling all accounts
• T4 preparation — year-end payroll slips for employees
• Software setup — QuickBooks, Xero, or Wave setup for a new client
• Catch-up work — bringing books current when a client has fallen behind

Hourly vs. Flat Monthly Fee

Hourly Billing

Hourly billing works well for new clients where the scope of work is not yet predictable, or for one-time projects like catch-up bookkeeping or software migration. Rates for Canadian bookkeepers typically range from $40–$90/hour depending on experience and location. Include a summary of hours worked on the invoice.

Flat Monthly Retainer

Most established bookkeeping practices prefer flat monthly retainers for ongoing clients. This provides predictable income and makes billing simple. The retainer should be clearly tied to a defined scope — if the client's transaction volume grows significantly, the retainer can be renegotiated. See our retainer invoice template for more detail on structuring retainer agreements.

Does HST Apply to Bookkeeping Services?

Yes. Bookkeeping services are taxable supplies under the Excise Tax Act. If you earn more than $30,000 in any 12-month period from bookkeeping and related services, you must register for GST/HST and charge the applicable rate to your clients. The applicable rate depends on where your client's business is located:

• Ontario clients: HST 13%
• Alberta clients: GST 5%
• BC clients: GST 5% (PST does not apply to bookkeeping services)
• Quebec clients: GST 5% + QST 9.975%
• Atlantic province clients: HST 15%

Many bookkeepers register voluntarily even before reaching $30,000 so they can claim Input Tax Credits (ITCs) on business expenses — accounting software subscriptions, computer equipment, home office costs, and professional development.

Scope of Services Description

The scope description on your invoice matters. It sets expectations, prevents scope creep disputes, and helps clients understand the value they are receiving. Rather than writing just "bookkeeping services — March 2026," be specific:

"Monthly bookkeeping retainer — March 2026. Includes: bank reconciliation for 3 accounts (RBC chequing, RBC savings, Visa business), accounts payable entry from vendor invoices, accounts receivable entry from customer payments, preparation of monthly income statement and balance sheet. Based on up to 75 transactions per month."

When a client needs work outside this scope — year-end preparation, a CRA audit, or training a new staff member on the software — bill that separately at your hourly rate and create an additional line item or a separate invoice.

Year-End Bookkeeping — Billing Separately

Year-end work is typically more intensive than regular monthly bookkeeping. Many bookkeepers charge a one-time year-end fee in addition to their monthly retainer, billed in January or February when the work is completed. This can range from $300–$1,500 depending on business complexity. Be explicit about this in your engagement letter so clients are not surprised.
