Freelancers need payment terms that are easy to follow
A good invoice does not make the client guess. It shows the invoice date, exact due date, payment method, late fee policy if used, and the total amount due.
Freelancers often use Net 7, Net 15, Net 30, or Due on Receipt. The right choice depends on client trust, project size, and how much cash buffer you have.
Payment terms by client type
| Client type | Safer term | Why |
|---|---|---|
| New client | Deposit plus Due on Receipt or Net 7 | Lower trust and higher risk |
| Trusted recurring client | Net 15 or Net 30 | Predictable payment behavior |
| Large company | Net 30, sometimes Net 60 | Internal payment process may be slower |
| Small urgent project | Due on Receipt | Short project, simple payment |
How to write a late fee clearly
A late fee clause should be plain, visible, and included before the invoice becomes overdue. Avoid vague wording. A clear sentence is better than a hidden paragraph.
Example: Invoices unpaid after the due date may be subject to a late fee of 1.5% per month on the outstanding balance, where permitted by applicable law.
- Show the original invoice amount.
- Show the late fee amount separately.
- Show the new total owed.
- Keep the tone professional and factual.

FAQ
Common questions
What payment terms should freelancers use?
For new clients, Due on Receipt, Net 7, or a deposit is safer. For trusted clients, Net 15 or Net 30 can work.
Can freelancers charge late fees?
Often yes if terms are disclosed and allowed by applicable law, but rules vary. Verify before relying on a late fee policy.
Should I write Net 30 or the exact due date?
Use both. Write Net 30 and also show the exact due date so the client does not have to calculate it.
How do I calculate a late fee?
Use the overdue balance, the late fee rate, and the number of overdue days or months. Keep the late fee separate from the original invoice amount.
