What to include on a software development invoice
Sprint, ticket or feature references
Mention the sprint, ticket or feature so the client can tie hours to deliverables.
Day or hourly rate
State the rate and the unit (hours or days) on every line.
Period covered
Include the date range, especially for monthly contractor invoices.
Expenses and licences
List third-party tools or hosting you purchased on the client's behalf separately.
Payment details
Add bank details or a payment link so payment is a single step.
Tips for getting paid on time
- Send time-based invoices at a fixed rhythm (weekly or monthly) so the client expects them.
- Attach a short timesheet if the client's process requires one.
- Use one invoice per client and per period for cleaner records.
Invoice requirements such as tax IDs, VAT or sales tax lines and numbering differ by country. Check what your local tax authority requires and include those details on your invoice.
