Net 30 payment terms explained
“Net 30” means payment is due 30 days after the invoice date. It is the most common payment term in business-to-business trade, and it is also the one small suppliers most often regret agreeing to. Here is what it actually means in practice, and how the alternatives compare.
What net 30 means on an invoice
The word “net” is the full amount — no discount. The number is the number of days the client has to pay. So an invoice dated 1 March with net 30 terms is due on 31 March. Nothing else needs to be on the invoice for the term to apply, but you should still print an explicit due date so there is no arithmetic to argue about.
Two details trip people up:
- When the clock starts. Standard practice starts it on the invoice date. Some larger buyers state terms from receipt of the invoice, or from the end of the month in which it arrived (“30 days end of month”, written 30 EOM). Those two variants can hand the client an extra two to four weeks.
- When a payment is “made”. A client who releases the payment on day 30 has not necessarily paid on day 30. If your contract is silent, the payment date is usually the value date in your account, not the date the client clicked send.
How the common terms compare
| Term | Due | Typical use | Risk for the supplier |
|---|---|---|---|
| Due on receipt | Immediately | Retainers, deposits, consumer work | Low — but clients often ignore it |
| Net 7 | 7 days | Small businesses, repeat clients, trades | Low |
| Net 14 | 14 days | Freelancers and small suppliers — a good default | Low to moderate |
| Net 30 | 30 days | The B2B default; corporate procurement | Moderate — you fund a month of work |
| Net 60 | 60 days | Large enterprises, some public bodies | High |
| Net 90 | 90 days | Very large enterprises; often imposed, not negotiated | High — a quarter of working capital |
A practical rule for a one-person business: default to net 14, accept net 30 for established clients, and price net 60 or net 90 accordingly or refuse them. Long terms are not free — they are a loan you are making to your client, and nothing on the invoice pays you interest for it.
Set terms once and print them every time
Payment terms belong in three places, all saying the same thing:
- In your contract or engagement letter, so the term is agreed before any work starts.
- On every invoice, as a visible due date plus a short line such as “Payment terms: net 14”.
- In the covering email, in one sentence — the person who approves the work is often not the person who reads the invoice.
Work out the exact due date from any term with the invoice due date calculator. It handles net 7 through net 90 and custom day counts.
Early payment discounts and late fees
Two clauses change behaviour more than any amount of chasing:
- Early payment discount. “2/10 net 30” means the client may deduct 2% if they pay within 10 days, otherwise the full amount is due in 30. It costs you 2% and typically buys two weeks of cash flow. Only offer it if you have margin.
- Late payment interest. A stated annual rate (or a flat fee) gives you a lever after the due date. See the late fee calculator for the numbers, and put the clause in the contract, not on the first overdue invoice.
When a net 30 invoice goes past the due date
Most late payments are administrative, not malicious. The invoice went to the wrong inbox, the PO number was missing, or the approver was on leave. A short reminder that names the invoice number, amount and due date resolves the majority of them; a firm second reminder with the late fee attached resolves most of the rest. Ready-to-send wording is in our payment reminder email templates.
If you are still unsure what must appear on the document itself, start with what to include on an invoice.
