Invoice Generator for Web Developers
Development invoices should map to milestones or sprints, with hours shown only for time-and-materials work.
How web developers should structure their invoices
- Fixed-price projects: invoice per milestone, never per hour — clients do not audit outcomes they approved.
- Hosting, domains and licenses are pass-through costs; keep them visible and separate.
- State the warranty period (usually 30 days bug fixes) so post-launch requests are not free.
The invoice above already contains the line items most web developers bill for. Adjust the rates to your own, delete what does not apply, and add anything specific to your engagement.
What a web developer invoice must include
- A unique, sequential invoice number — never reuse or skip numbers.
- Your business name and address, plus your tax or registration number if you have one.
- The client's name and address, and a purchase order reference if they use one.
- Each service on its own line with quantity and rate, so the total is auditable.
- Tax shown separately with the rate, and the total clearly stated.
- Payment terms and the due date — not only in your contract.
Web Developers invoicing questions
Should I bill hourly or fixed?
Fixed per milestone when scope is clear; hourly retainer for maintenance. Mixed is fine but must be on separate invoices.
How do I invoice for change requests?
Separate invoice, separate approval. Never fold it into the project invoice — that is how fixed-price projects lose money.
Who owns the code?
You do, until final payment. State it in the invoice footer: "IP transfers upon receipt of final payment."
