Frequently Asked Questions
HST applies in Ontario, Nova Scotia, New Brunswick, and Newfoundland and Labrador. Other provinces use GST plus their provincial sales tax (PST). Alberta charges only GST. The tax rate depends on where the work is performed, not your business location. If you work across provinces, apply the correct rate for each location and itemize accordingly on your invoice. Always confirm your client's province and verify current rates before invoicing.
Retainage is a percentage—typically 5–10%—that clients withhold from payment until project completion, serving as security against defects or incomplete work. It's standard practice in construction contracts and often required by law for large projects. You should itemize retainage separately on your invoice so clients anticipate the deduction and you can clarify when it will be released, usually 30–60 days after final completion.
Separate these into distinct line items to ensure clarity for both you and your client. List materials with specific descriptions (concrete, lumber, fixtures); show labor as hourly rates or fixed prices per task; itemize equipment rental with duration and daily/weekly rates. This breakdown helps with accurate cost tracking, justifies pricing to clients, and simplifies accounting and change order management when scope adjustments occur.
Construction invoices commonly operate on Net 30 to Net 60 terms, though specialized services may be Net 14 or Net 7. Larger projects often use Net 45. Clearly state your payment terms on every invoice and in your contract to prevent misunderstandings and cash flow issues. Consider offering a small early-payment discount (1–2%) if you need faster settlement, and always specify your payment method (bank transfer, check, credit card).
Subcontractors invoice their general contractor or project manager with detailed labor and material breakdowns, while general contractors invoice clients for the overall project scope. Subcontractor invoices often require business license numbers, proof of insurance, and WCB account information to satisfy client compliance requirements. Always review your subcontract terms for specific invoicing requirements, as these vary by general contractor, province, and project size.
Invoice each province's work separately with its applicable sales tax rate, clearly delineating which line items apply to which location. Include the province abbreviation (AB, ON, BC) next to each line item or in a separate column if needed. Keep detailed records of where and when work occurred for tax compliance and potential audits. Large multi-provincial projects may benefit from consulting an accountant to ensure correct apportionment and tax treatment.
Many clients—especially large contractors and property developers—require proof of active WCB (Workers' Compensation Board) coverage before processing payment. While not always legally required on the invoice itself, including your WCB account number or clearance certificate as a reference or attachment demonstrates compliance and can accelerate payment. Check your contract terms or ask your client directly about their requirements.
Create separate invoices for each completed phase or milestone, detailing only the work finished during that period. Include a project reference number or phase identifier so clients can track progress against the contract scope. Number invoices sequentially (e.g., Phase 1 of 4) to help clients understand the full payment schedule. This approach prevents disputes over timing, simplifies progress tracking, and makes payment processing clearer for both parties.
