Why should every freelancer invoice tie back to a written scope or master agreement?
Clients and auditors reconstruct the story from emails, statements of work, and invoices. When your line descriptions repeat the same language as the signed scope, you reduce payment delays and support the gross income figures you later carry to Form T2125. The CRA reminds sole proprietors that income records should show the date, amount, and source of income, with original documents such as sales invoices and fee statements kept to support those entries (Canada Revenue Agency, Business records, updated 2024).
