For a freelance invoice, identify the client and project, separate hourly work from fixed-price deliverables, and show the agreed amount for each. Name approved extra work clearly and state the due date and payment reference.
In this example
Start with the billing arrangement
The invoice should reflect what you and the client actually agreed, not simply the number of hours you remember spending. Before entering a line, decide whether that part of the work is hourly, a fixed deliverable or a separately agreed stage.
- Hourly: identify the task or billing period, enter the recorded hours and use the agreed rate.
- Fixed price: describe the deliverable and use a quantity of one with its agreed price.
- Project stage: name the stage being billed and cross-check it against your own project records.
For fixed-price work, do not also bill the hours already covered by that price. NineBrief does not track time, approvals or cumulative project billing for you.
A freelance invoice with two different types of work
This fictional invoice combines an agreed illustration package with additional production time. The numbers demonstrate structure, not market rates. Applicable tax is omitted for this arithmetic example only.
| Description | Quantity | Rate (USD) | Amount (USD) |
|---|---|---|---|
| Three cover concepts — fixed-price brief | 1 package | 280.00 | 280.00 |
| Approved extra production — 23 September | 2 hours | 55.00 | 110.00 |
The extra production line is distinct from the original package. Keep the client’s approval in your own project records; writing “approved” on the invoice does not establish that approval happened.
Make revisions and extras unambiguous
“Revisions” can mean included work or an additional charge. Use a description that connects the line to an actual agreement, such as “Additional product-label layout — approved change dated 23 September.” Do not assume every revision is billable.
If usage, licensing or ownership terms matter to your creative work, agree and record them separately as appropriate. An invoice description is not a substitute for a complete agreement, and NineBrief does not manage licenses or sign contracts.
For staged work, check your own records before sending a new invoice. A request for an upfront amount is not a payment already received. Do not enter it in “amount paid” merely to show an intended deposit.
Build and check it in NineBrief
- Gather the billing name, project reference and agreed scope.
- Use the Invoice Generator for the amount you are billing now. Use the Quote & Estimate Generator for proposed work instead.
- Add separate lines for the package and the additional hours. Check the unit, quantity, rate, currency and total.
- Add the agreed due date and verified payment instructions. Review the clean preview, save the PDF and export an editable JSON backup.
The first-invoice guide explains the editor, PDF download and backup steps. Selecting a tool here opens the existing generator; it does not silently prefill or replace your current draft.
Before you send a freelance invoice
- The client can match each line to a brief, period or deliverable.
- Included work has not been charged twice.
- Any extra work and expenses have the approval your agreement requires.
- The amount now due does not accidentally repeat an earlier stage.
- The PDF and editable backup are stored with your project records.
Can I use this for a monthly client?
Yes, you can manually prepare an invoice for the agreed period. Put the period in the description. NineBrief does not automatically generate recurring invoices or reminders.
