When to use this template
Use this template for web development work — website builds, feature development, or ongoing maintenance. Milestone billing keeps cash flow steady on longer projects.
Fields to include
- Developer and client details
- Project and milestone reference
- Line items per development phase
- Hosting, domains, and licenses (if billed by you)
- Maintenance agreements
Sample line items
- Phase 1 — build & setup (of 3)1 × $1500.00 = $1500.00
- Custom feature: booking module1 × $800.00 = $800.00
- Hosting & domain — annual1 × $120.00 = $120.00
Practical tips
- Invoice per milestone (e.g., build, content, launch) for long projects.
- Separate pass-through costs (hosting, domains) from your labor.
- If you run a maintenance retainer, bill it monthly in arrears or advance — and say which.
Frequently asked questions
Should developers take a deposit?
A 20–50% deposit before starting is standard practice and protects you if the project is cancelled early.
How do I bill milestone payments?
Agree on milestones in writing (e.g., setup, build, content, launch) and invoice each one as it's reached. Invoala lets you number and track each invoice.
What about hosting bills I pay on the client's behalf?
Pass them through as clearly labeled line items with receipts or references, exactly like ad spend in marketing.
