Web Developer Service Agreement Template

Free template · reviewed by Riya Menon, Contracts writer, Signr · updated July 2026

A Web Developer usually reaches for a Service Agreement when for a defined project with a clear start, deliverables and end. This free template does one job well: it defines the scope, timeline, payment and ownership for a one-off project. It is written for how web developers actually work — around a marketing site or web-app build with defined milestones, the familiar headache of endless post-launch bug reports being treated as free work, and getting paid on staged payments tied to milestones, often 30% up front and the rest on acceptance. Use a Service Agreement rather than something looser, because for open-ended ongoing work — use a retainer instead. Edit any line to fit your rates and terms, then send it for e-signature in a couple of minutes — no account for your client, and it is legally binding under the ESIGN Act and eIDAS.

Common mistakes web developers make

A scope that is too vague

If the agreement does not name exactly what working, deployed source code and a live site is included, endless post-launch bug reports being treated as free work follows. List the deliverables line by line.

No cap on revisions

Without a revision limit, new pages, integrations or design changes added after the spec is signed off quietly becomes unpaid work. Fix the number of rounds in writing.

Handing over work before payment

Say that source-code ownership transferring only on final payment, plus third-party and open-source licences only pass on full payment, or a Web Developer loses all leverage once the files are out.

FAQ

When should a Web Developer use a service agreement instead of a retainer?

Use it for a marketing site or web-app build with defined milestones — a defined job with a clear end. For continuing month-to-month work, a retainer fits better.

Does a service agreement set out how a Web Developer gets paid?

Yes. It fixes your fee and terms, which for web developers is usually staged payments tied to milestones, often 30% up front and the rest on acceptance.

Is this Web Developer Service Agreement legally binding once signed?

Yes. Once you and your client sign it — including with an electronic signature — this Service Agreement is a binding contract under the ESIGN Act, eIDAS and similar laws in most countries.

What if a client asks a Web Developer for more than was agreed?

Point them back to the scope. Extra work such as new pages, integrations or design changes added after the spec is signed off is quoted separately — that is exactly what the written terms are for.
