Bookkeeping Invoice Template - Canada

GST (5%) applies federally to most bookkeeping services, but HST (13% or 15%) combines GST and provincial sales tax in Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. Outside HST provinces, apply GST plus applicable provincial sales tax. Verify your client's provincial location and apply the correct rate. Keep detailed records of the province and tax calculation for each invoice—this documentation is essential for GST/HST returns and CRA compliance.

Break down services to show value and help clients understand their charges. Common line items include monthly bookkeeping, bank reconciliation, accounts receivable and payable processing, payroll processing, financial statement preparation, GST/HST return preparation, expense categorization, and account reconciliations. Itemizing lets clients see exactly which services they received, supports future billing adjustments, and provides documentation for tax deduction purposes. This transparency strengthens client relationships, simplifies audits, and reduces disputes over charges.

Monthly retainers are increasingly standard for Canadian bookkeeping because they provide predictable income and consistent client budgeting. Retainers work best for recurring services like monthly general ledger maintenance, bank reconciliation, and payroll administration. Hourly billing suits project-based work such as initial setup or GST return preparation. Many bookkeepers use a hybrid approach: charge a base monthly retainer for standard services, then bill additional hours for extra work. Communicate your billing structure clearly in writing to align client expectations with your invoice.

Payment terms for bookkeeping services typically range from Net 7 to Net 30 days, with Net 15 being most common. Many bookkeepers require payment by a specific date each month to maintain cash flow, especially if they handle the client's payroll or vendor payments. Some impose a small late fee (1.5% monthly interest or fixed penalty) to encourage timely payment. Consider invoicing after delivering service—mid-month invoicing is standard practice. Clearly state your payment terms, preferred payment method, and any early payment discount to maintain professional relationships and reduce payment delays.

For multi-province clients, invoice each provincial location separately or provide a detailed breakdown showing which services apply to which province with the appropriate tax rate applied to each section. If the client has a head office in one province but you serve multiple locations, apply the tax rate where service is primarily performed. Document your allocation method to justify calculations during CRA audits. For efficiency, establish a schedule showing each location, its tax rate, and allocation percentage. This approach prevents over or underpaying tax and demonstrates clear record-keeping for CRA inquiries.

Retain invoice copies, time tracking or work logs showing completed tasks, client communication authorizing work, receipts for reimbursable expenses, bank statements showing payment, and supporting documentation like reconciliations or reports delivered. The CRA requires businesses to keep records for six years, and invoices are key records proving income earned and tax collected. Organize documents by client and month for quick retrieval during tax filing or CRA inquiries. Maintain digital backups separate from your primary computer to prevent data loss that could jeopardize compliance records.

Clearly state the retainer amount, billing period (monthly or quarterly), and included services on the invoice. List additional charges or overage fees separately from the retainer line so clients immediately see base costs versus extras. If you haven't used the full retainer, note whether unused hours roll over or expire. Issue retainer invoices consistently on the same date each month—ideally before service delivery or shortly after month-end closing—to establish predictable billing. This structure simplifies accounting for both parties, reduces scope creep disputes, and provides the financial certainty that attracts bookkeeping clients.

GST/HST return preparation is often billed separately because it's a discrete project with specific timing—usually due within three to six months of quarter-end or fiscal year-end. Invoice this service as a separate line item or invoice to show its distinct nature and different deadline. Include complexity factors in your description: for example, GST/HST return preparation with input tax recovery analysis or multi-location GST/HST return coordination. This clarity helps clients understand why compliance services command different fees than routine bookkeeping. Itemized documentation makes it easy to justify charges based on hours, complexity, and CRA submission risk.
