Late Payment Invoice Template for Canada

When a customer fails to pay within agreed terms, you need a legally compliant approach to collect what's owed. A Late Payment Invoice provides formal notice of overdue amounts while protecting your legal position under Canadian law. This document serves as both a payment reminder and official demand that can support future collection efforts or legal proceedings.

When do you need this document?

You'll need a Late Payment Invoice when payment terms on your original invoice have expired without payment. This commonly occurs in business-to-business transactions where payment terms like "Net 30" have passed, or in service contracts where milestone payments are overdue. The document becomes essential when moving beyond informal payment reminders to formal collection procedures. It's particularly important when dealing with commercial clients who may dispute payment terms or when preparing for potential legal action. Many businesses use this as a standard step in their accounts receivable process before engaging collection agencies or legal counsel.

Key legal considerations

Your Late Payment Invoice must comply with the federal Interest Act, which governs how interest rates are calculated and expressed on overdue payments. You cannot charge interest rates exceeding legal limits, and all interest calculations must be clearly stated in annual percentage terms. Provincial consumer protection laws may impose additional restrictions, especially for business-to-consumer transactions. The document should reference your original contract terms that authorized late payment charges. Include precise calculations showing how interest and fees were determined, as this transparency protects against legal challenges. Be aware that collection practices must comply with provincial Collection and Debt Settlement Services Acts, which regulate language and frequency of collection notices.

Legal requirements in Canada

Under Canadian law, your Late Payment Invoice must clearly identify the original invoice details, including invoice number, date, and original due date. The outstanding principal amount must be stated separately from any interest or late fees. Interest calculations must conform to the Interest Act's requirements for annual rate expression and maximum allowable rates. Provincial legislation may require specific disclosures about consumer rights or collection procedures. For GST/HST registered businesses, you must consider tax implications on late payment charges under the Excise Tax Act. The document should maintain professional language that avoids harassment or threats, as prohibited under provincial debt collection regulations. Keep detailed records of all collection notices sent, as provincial Limitations Acts set time limits for debt collection legal action.
