Invoice Payment Terms Explained: Net 30, Net 15 and Due on Receipt
Key points
- Net 30 means 30 calendar days from the invoice date, not 30 business days.
- Shorter terms get paid sooner. Net 7 and Net 14 are normal for freelancers and small clients.
- Always write the actual due date next to the term. A date cannot be misread; a term can.
- Expect to be paid late regardless: the average small-business invoice took 28.8 days in 2026, according to Xero.
What are invoice payment terms?
Payment terms are the deadline you set for payment, plus any conditions attached to it. They appear on the invoice as a short code such as Net 30 and, ideally, as an actual date. They are a commercial decision, not a formality: the term you pick changes when the money arrives.
What do Net 7, Net 15, Net 30 and Net 60 mean?
The number is calendar days from the invoice date. Net 30 on an invoice dated 1 January is due 31 January. It is not 30 working days, and it does not start when the client opens the email.
| Term | Meaning | Best for |
|---|---|---|
| Due on receipt | Payment expected immediately | Small jobs, new clients, one-off work |
| Net 7 | Due 7 calendar days after the invoice date | Freelancers billing individuals or small businesses |
| Net 14 | Due 14 calendar days after the invoice date | The common middle ground for ongoing client work |
| Net 30 | Due 30 calendar days after the invoice date | Corporate clients, whose systems often assume it |
| Net 60 or Net 90 | Due 60 or 90 calendar days after the invoice date | Large enterprises and public sector, usually non-negotiable |
| 2/10 Net 30 | 2% discount if paid within 10 days, otherwise due in 30 | Buying faster payment when cash flow matters more than margin |
| 50% upfront | Half before work starts, the balance on delivery | Projects large enough that non-payment would hurt |
The common terms, what they mean, and where each one fits.
Which payment terms get invoices paid fastest?
Shorter terms, stated as a date, with the payment method on the invoice. The term itself sets an expectation, but the two things that move payment dates are removing ambiguity and removing friction.
Write "Due 5 September 2026" rather than only "Net 30". Include bank details or a payment link on the invoice itself. Both sound trivial and both remove a round trip of email that can add a week.
How late do invoices actually get paid?
Late enough that you should plan for it. Xero's US Small Business Insights put the average wait at 28.8 days in 2026. QuickBooks' 2026 Small Business Late Payments Report found 59% of US small businesses carrying invoices overdue by 30 days or more, up from 47% a year earlier, with an average of $17,700 outstanding.
The practical reading: treat your terms as the start of the conversation rather than the end of it, and do not build a cash-flow plan that assumes payment on the due date.
Should you charge a late fee?
State one even if you rarely enforce it. A clause such as "1.5% per month on overdue balances" changes how an invoice is prioritised, because it gives the person chasing internally something concrete to point at.
For it to be enforceable it generally has to be agreed in advance, whether in a contract or stated clearly on the invoice. Rules differ by country, and some set a statutory rate you can claim even without your own clause, so check your local position before relying on it.
How do you write payment terms on the invoice?
Three things in one short block: the deadline, the accepted payment methods, and the late fee. Anything longer stops being read.
A worked example: "Payment due within 30 days of the invoice date, by 5 September 2026. Bank transfer to Access Bank, account 0123456789. A late fee of 1.5% per month applies to balances unpaid after the due date."

Frequently asked questions
What does Net 30 mean on an invoice?
Net 30 means the full amount is due within 30 calendar days of the invoice date, not 30 business days. An invoice dated 1 January with Net 30 terms is due 31 January. Write the actual due date alongside the term so there is nothing to interpret.
What does 2/10 Net 30 mean?
The client may take a 2% discount if they pay within 10 days, otherwise the full amount is due within 30 days. It is a way of buying faster payment. On a $10,000 invoice the discount costs you $200 to be paid roughly three weeks sooner.
What payment terms should a freelancer use?
Net 7 or Net 14 for individuals and small clients, and Net 30 for corporate clients who will not negotiate. For anything substantial, take a deposit up front rather than extending the whole amount on credit.
Can I charge interest on a late invoice?
Usually yes, provided the rate was stated before the work or on the invoice itself. A common clause is 1.5% per month on overdue balances. Rules vary by country, and some jurisdictions set a statutory rate you can claim even without a clause.
