Definition
A final invoice is the last invoice issued on a project, sent when all work is complete. It shows the total contract value, lists any deposits or progress payments already received, and states the remaining balance due. It closes out the project financially for both parties.
Final invoice in practice
A final invoice should reference earlier invoice numbers and clearly show the math from total project value to balance due. This prevents clients from paying the full amount twice or disputing amounts already settled.
Frequently Asked Questions
Should the final invoice show the deposit?
Yes. Show the full project total, subtract the deposit and any progress payments with their invoice numbers and dates, and present the balance due as the amount to pay.
