Developer Billing Models: Hourly, Milestones, and Retainers
Developers invoice using a few common models depending on the engagement.
1) Hourly billing
Great for ongoing work, maintenance, and variable scope.
2) Milestone pricing
Fixed fees for defined deliverables (features, releases, integrations).
3) Monthly retainers
Reserved capacity for product teams and ongoing support.
Using a “Repo/ticket ref” field can speed up approvals because clients can match billed work to tracked tasks.
Deliverables to List on Software Development Invoices
Deliverables make invoices clearer—especially for milestone work.
Common deliverables- Feature shipped or module delivered
- Integration completed (API, payments, auth)
- Bug fixes and stability improvements
- Deployment and release tasks
- Documentation updates
Maintenance, Bug Fixing, and Post-Launch Support
Many developer invoices include ongoing support work.
Best practices- Separate new development from maintenance line items
- Itemize deployment/release support when significant
- Keep a service period so recurring invoices are easy to compare
