Project builds, integrations, and ongoing retainers - developer invoices mix one-off work with recurring fees. This template keeps both clear so you get paid on time for each.
Tip: Bill milestones (deposit, mid-project, on launch) instead of one lump sum at the end - it smooths cash flow and reduces risk.
This is the same clean layout as our freelance invoice template, pre-filled with the lines web developers bill for. Not sure what belongs on an invoice? Read what to put on an invoice.
Fixed-price per milestone works best for defined builds; hourly suits open-ended or maintenance work. Many developers do both - fixed for the build, hourly for changes.
Send the invoice the day you finish, include a one-tap payment link, and state clear terms with a late fee. GigPaper adds all three automatically and chases overdue invoices for you, so you are not the one following up.
GigPaper builds the invoice, adds your payment link and terms, and sends it as a tap-to-pay link your client never makes an account for. 30 days free, no card.
