Contract invoice template
Contract invoice template is used to bill under a signed contract, often referencing a PO, project number, or milestone. It should list deliverables or phases, amounts tied to the contract, cumulative billing to avoid overruns, and payment terms. Supporting documents (e.g., timesheets, acceptance) help with approval and audit.

An invoice should include your business or name, the customer’s details, the date and invoice number, and a line-by-line breakdown of what was provided. Including payment terms—such as due on receipt, Net 15, or Net 30—helps you get paid on time and keeps records clear for taxes.

Frequently Asked Questions
- What should a contract invoice include?
- Contract and PO number, project name, invoice number, description of work or milestone, amount, cumulative billing to date, total contract value, payment terms, and any required supporting documents.
- What is milestone billing?
- Billing when predefined milestones are completed and accepted. Each invoice covers one or more milestones with a fixed amount; avoids billing ahead of delivery and ties payment to deliverables.
- How do I avoid overbilling on a contract?
- Show cumulative amount billed and contract value on each invoice. Only bill for completed, accepted work or milestones. Use a cap or approval step so you never exceed the contract total.
