7. What does the CRA consider to be acceptable documentation? Documentation, such as agreements, invoices, and receipts, must clearly identify the type and quantity of goods purchased or services provided, including, but not limited to, the following information:
· information that clearly identifies the vendor/contractor, their business address and, if applicable, the GST/HST registration number;
· a description of the goods and the date when the goods were purchased;
· the date the goods were delivered (keep your delivery slip as proof) and/or when the work or services were performed;
· a description of the work (including the address of where the work was performed);
· the amount of the invoice; and
· proof of payment.
