Final Payment and Balance Due Invoice

Final Payment Invoice Guide

The final invoice closes out a project by billing the remaining balance after deposits and milestone payments. It should provide a clear accounting of all previous payments.

Structure of a Final Invoice

A final invoice should include:

1. Total project value -- the full agreed amount
2. Previous payments -- listed as credits
3. Balance due -- the remaining amount
4. Deliverables summary -- what was completed
5. Handoff details -- file transfer, access credentials, etc.

Final Invoice Best Practices

1. Mark as "FINAL INVOICE" prominently
2. List all previous invoices with dates and amounts
3. Confirm deliverables are complete before sending
4. Include handoff terms -- when files/access will be transferred
5. Set shorter payment terms (Net 15 instead of Net 30) for final payments
