When progress billing helps
Long projects strain cash flow if you wait until the end. Progress invoicing lets you bill monthly, by completion percentage, or by deliverable while work continues.
- Long projects and retainers
- Construction and dev sprints
- When delivery spans months
Choose a billing method
Percent-complete billing works for construction and software. Deliverable-based billing fits creative work. Match the method to what clients can approve quickly.
- Hours or % complete
- Deliverables this period
- Cumulative total billed
Show remaining contract value
Each progress invoice should show work completed, amount billed to date, and balance remaining. Transparency reduces disputes on the final invoice.
- Compare to approved estimate
- Note scope changes in writing
- Attach timesheet summary if hourly
