Progress Invoicing Basics

Bill large projects in stages as work is completed.

  • Progress billing matches payment to work completed.
  • Show percent complete or hours to date.
  • Clients need to see what changed since last invoice.

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
