Billing tips for developers

  • Tie each invoice to sprint or milestone names the client recognizes.
  • Separate new features from maintenance/support hours.
  • For retainers, show hours used vs. hours remaining.

Frequently asked questions

How do developers structure invoices?

By milestone or sprint for project work, hourly for ad-hoc work, and monthly for retainers — often all three across different clients.

Should developers bill for meetings?

If meetings are part of delivery, include them in your hours. State your policy in the contract so invoices never surprise anyone.
