How web developers bill
Developers bill hourly, per sprint/milestone, or as a monthly retainer for maintenance. Fixed-price projects are usually split into a deposit plus milestone payments.
What to put on a web developer invoice
- A clear scope reference (which features/sprint this invoice covers) so clients can approve fast.
- Your hourly rate and hours, or the milestone, so the amount is easy to verify.
- Any third-party costs passed through (hosting, domains, paid APIs) as separate lines.
- The essentials every invoice needs: your details, the client's, a unique number, issue and due dates, an itemised list, the total, and how to pay.
Payper builds all of this for you — add your logo and payment methods once and they appear on every invoice. Create your web developer invoice →
