Payment Terms: Net 30 and Others

Payment terms tell your client when to pay and what happens if they do not. Here is what each common term means, how to calculate the due date and what the law adds.

Common payment terms and what they mean

The examples below all start from an invoice dated 15 March 2026. March has 31 days and April has 30.

Term Meaning Due date for a 15 March 2026 invoice
Due on receipt Pay as soon as the invoice arrives 15 March 2026 (on receipt)
Net 7 Full amount within 7 days 22 March 2026
Net 15 Full amount within 15 days 30 March 2026
Net 30 Full amount within 30 days 14 April 2026
Net 60 Full amount within 60 days 14 May 2026
EOM Due at the end of the month of the invoice 31 March 2026
Net 30 EOM 30 days after the end of the invoice month 30 April 2026
15 MFI 15th of the month following the invoice 15 April 2026
2/10 Net 30 2% discount if paid within 10 days, otherwise full amount in 30 Discount until 25 March; full amount by 14 April 2026
CIA / CWO Cash in advance / cash with order Before work starts
50% upfront Half on acceptance, the rest on delivery or by the due date Split payment

How to count Net 30: 15 March + 16 days takes you to 31 March, and 14 more days to 14 April, a total of 30 days. Net 60 adds another 30 days: 14 April + 16 days is 30 April, plus 14 is 14 May.

EOM conventions differ between industries; some read “EOM” as “Net 30 EOM”. Write the actual due date on the invoice to remove any doubt. In the invoice generator you set the payment terms in the Details step; add the exact due date there too.

Early-payment discounts: the 2/10 Net 30 maths

On a $5,000.00 invoice with 2/10 Net 30:

  • Paid within 10 days: $5,000.00 × 2% = $100.00 discount, so the client pays $4,900.00.
  • Paid on day 11 to day 30: the client pays the full $5,000.00.

What does the discount cost you? You give up $100.00 to receive $4,900.00 twenty days earlier (day 10 instead of day 30). That is 100 / 4,900 = 2.04% for 20 days. Over a year: 2.04% × 365 / 20 ≈ 37.2%. That is a high price for faster cash, so treat early-payment discounts as a deliberate choice, not a default.

In VAT countries, check how a discount affects the VAT; in Germany, for example, discounts agreed in advance must be indicated on the invoice under § 14 Abs. 4 Nr. 7 UStG.

Late fees and statutory interest

European Union

The EU Late Payment Directive (2011/7/EU) sets the baseline for business-to-business payments:

  • Payment terms between businesses should normally not exceed 60 days, unless expressly agreed and not grossly unfair to the supplier.
  • Public authorities must pay within 30 days (60 in exceptional cases).
  • Late payers owe statutory interest of the reference rate plus at least 8 percentage points.
  • The supplier can claim a fixed €40 compensation for recovery costs.

Germany: a debtor is in default 30 days after receiving the invoice (§ 286 Abs. 3 BGB); for consumers only if the invoice points this out. Default interest is 9 percentage points above the base rate for B2B and 5 points for consumers (§ 288 BGB), plus a €40 flat fee for B2B (§ 288 Abs. 5).

Netherlands: statutory commercial interest (wettelijke handelsrente) applies. Without an agreement, the payment term is 30 days (art. 6:119a BW). Since 2021, large companies may agree terms of no more than 30 days with SMEs.

United Kingdom

Under the Late Payment of Commercial Debts (Interest) Act 1998, a business can claim interest of 8% above the Bank of England base rate plus fixed compensation:

Debt Fixed compensation
Up to £999.99 £40
£1,000 to £9,999.99 £70
£10,000 or more £100

Worked example: a £2,400 invoice is paid 30 days late. Assume, for illustration only, a base rate of 4%; check the current rate on the day the debt became late. The statutory rate is then 4% + 8% = 12% a year. Interest: £2,400 × 12% × 30 / 365 = £23.67. Compensation: £70. Total claim: £2,400 + £23.67 + £70 = £2,493.67.

United States

There is no general federal late-payment rule for private business transactions. Late fees and interest depend on your contract and state law, including any usury limits. The federal Prompt Payment Act covers payments by federal agencies. Put any late fee in your agreement and on the invoice, for example “1.5% per month on overdue balances, where permitted by law”, and check your state’s rules.

How to choose your payment terms

  • Match your cash needs. Freelancers with little buffer often use Net 7 or Net 15, or ask for a deposit.
  • Match your client. Large companies often have fixed payment runs and may insist on their own terms. In the EU, terms beyond 60 days between businesses need a clear agreement.
  • Use deposits for big jobs. A share upfront reduces your risk. See quote vs estimate for deposit wording, and check local limits on deposits for home-improvement work.
  • Be consistent. Put the same terms in your quote, contract and invoice.
  • Write the date. “Due 14 April 2026 (Net 30)” beats “Net 30” alone.

Reminders and overdue invoices in our tool

After you download an invoice, mark it as Sent. In My documents it switches to Overdue once the due date passes unpaid, and the totals show what is outstanding, what is overdue and what was paid this year. For each overdue invoice the tool offers a polite reminder text to copy or open as an e-mail draft; we never send it for you. You can also download a calendar reminder (.ics) for the due date and add it to your calendar app.

When the payment arrives, click Mark as paid and, if needed, create a receipt from the invoice. New to invoicing? Start with how to make an invoice, check what to include on an invoice, or grab a blank invoice template.

Frequently asked questions

What does Net 30 mean on an invoice?
Net 30 means the full amount is due 30 calendar days after the invoice date. An invoice dated 15 March 2026 with Net 30 is due on 14 April 2026. “Net” means the full invoice amount, with no discount for paying early.
Does Net 30 include weekends?
Yes. The 30 days are calendar days, not business days, unless your contract says otherwise. If the due date falls on a weekend or holiday, clients often pay on the next business day, so it helps to write the exact due date on the invoice.
What does due on receipt mean?
The client should pay as soon as they receive the invoice. In practice most clients pay within a few days. Because the timing is vague, some businesses prefer a short fixed term such as Net 7, which gives a clear date for reminders.
Is 2/10 Net 30 worth offering?
It speeds up cash flow but it is expensive: giving up 2% to be paid 20 days sooner works out at roughly 37% a year. Offer it if you need cash quickly or if late payers are costing you more than the discount. For most small invoices, a clear Net 15 or Net 30 is enough.
Can I charge interest on a late invoice?
In the EU and the UK, business customers who pay late owe statutory interest and a fixed compensation amount by law, even if your invoice does not mention it. In the US it depends on your contract and state law. State any late fee clearly on the invoice and in your agreement.
