14 Days Payment Terms: Meaning and Wording

"Payment due within 14 days" is one of the most common lines on a UK small-business invoice. 14 days payment terms mean the customer has two weeks from the invoice date to pay the full amount, so an invoice dated Tuesday 10 November is due on Tuesday 24 November. It is the same thing as "Net 14", and it gives a fast, predictable payment cycle without feeling unreasonable to most business customers.

This guide covers exactly what the term means, copy-ready wording, a filled-in sample invoice, how UK late payment rules apply, and the mistakes that cause 14-day invoices to drift to 30 or 60 days.

What 14 days payment terms mean

The phrase sets the length of credit you are giving your customer. Unless your contract states otherwise:

• The clock starts on the invoice date. Some customers start it on receipt, so agree this upfront if it matters.
• Days are calendar days. Fourteen calendar days is exactly two weeks.
• The full balance is due. Part payments within 14 days do not satisfy the term unless you agreed instalments.

The difference between the invoice date and the due date catches people out more often than you might expect; our article on invoice date vs due date explains how each is used.

How to count 14 days

Add 14 to the invoice date. Because 14 days is exactly two weeks, the due date always lands on the same weekday.

Invoice date	Due date (14 days)
Tuesday 10 November 2026	Tuesday 24 November 2026
Monday 23 November 2026	Monday 7 December 2026
Friday 18 December 2026	Friday 1 January 2027 (bank holiday in the UK)
Saturday 31 January 2026	Saturday 14 February 2026

When the due date lands on a weekend or bank holiday, many customers pay on the next working day. If that matters to you, date the invoice so the deadline falls on a working day, or state "or the preceding working day".

14 days payment terms wording

Choose the wording that fits where it will appear. Always include the specific due date as well as the term.

On the invoice, next to the total

Payment terms: 14 days. Due date: 24 November 2026.

In the invoice footer

Please pay within 14 days of the invoice date by bank transfer to the account shown, quoting the invoice number. Thank you.

With a late payment notice (UK business customers)

Payment is due within 14 days of the invoice date. We reserve the right to claim interest and debt recovery costs under the Late Payment of Commercial Debts (Interest) Act 1998 on any amount not paid by the due date.

In terms and conditions or a quote

Invoices are payable in full within fourteen (14) days of the invoice date. Where payment is not received by the due date, we may suspend further work until the account is settled.

Make sure the same terms appear on your quote, contract and invoice. For a broader set of clauses, see our guide to invoice terms and conditions.

Sample invoice with 14 day terms

A sole trader electrician invoicing a small business customer might lay it out like this. The trader is not VAT registered, so no VAT is charged; our guide to invoicing when you are not VAT registered explains what to include instead.

Field	Example
Invoice number	EL-2026-071
Invoice date	10 November 2026
Payment terms	14 days
Due date	24 November 2026
Labour	Replace consumer unit, 6 hours @ £55 = £330.00
Materials	Consumer unit and breakers = £185.00
Certificate	Electrical installation certificate = £60.00
Total due	£575.00
Bank details	Account name, sort code, account number; reference EL-2026-071

Why 14 days is such a popular choice

• It fits a fortnightly rhythm. Many small businesses process supplier payments weekly or fortnightly, so 14 days usually catches at least one payment run.
• It halves the wait compared with 30 days. If you bill £8,000 a month evenly, moving from 30 to 14 days reduces the money typically owed to you from about £8,000 to about £3,700 (£8,000 x 14 / 30 = £3,733).
• It sounds reasonable. Customers rarely object to two weeks, whereas seven days or due on receipt can meet resistance from businesses.

UK late payment rules and 14 day terms

In the UK, payment terms between businesses are largely a matter of agreement, but there are statutory backstops. According to GOV.UK's late commercial payments guidance:

• If no payment date is agreed, payment is late 30 days after the customer receives the invoice or you deliver the goods or service, whichever is later.
• Agreed payment periods are generally up to 60 days for business transactions and 30 days for public authorities.
• When a business customer pays late, you can claim statutory interest and fixed debt recovery costs.

Statutory interest is set at 8 percentage points above the Bank of England base rate (the reference rate for the relevant six-month period). Our guides to statutory late payment interest and the UK late payment law in 2026 walk through the calculation. These rules apply to business-to-business transactions; consumers are treated differently. This section is general information, not legal advice.

How to get paid within 14 days

1. Confirm terms before the job. Put "payment within 14 days" in your quote and ask the customer to accept it.
2. Invoice on completion. Send the invoice the same day the work is finished or goods are delivered.
3. Check the details. Make sure the customer's name, any purchase order number and your bank details are correct. Errors give accounts teams a reason to hold payment.
4. Remind three days before. A brief email with the invoice reattached is enough.
5. Chase the day after. Then escalate after a week. Our past due invoice letter template gives firm but polite wording.

Common mistakes

• "Strictly 14 days" with no due date. The word "strictly" adds tone, not clarity. A date adds clarity.
• Terms that contradict the customer's purchase order. Large customers often send POs stating their own terms. Resolve the conflict before you start work.
• Late invoicing. If you send an invoice three weeks after the job, you have effectively offered 35 days of credit.
• Threatening interest you never claim. If you include late payment wording, be prepared to apply it, or customers learn to ignore it.

14 days payment terms in other countries

Fourteen-day terms are widely used outside the UK too, but the legal backdrop differs.

• Ireland and the EU: EU member states implement a late payment directive that sets default periods and caps for business-to-business and public sector payments. Fourteen days sits comfortably within those limits.
• Australia and New Zealand: "14 days" and "Net 14" are common small-business terms. Larger businesses may run their own supplier payment policies, so check before quoting.
• United States: "Net 15" is the more familiar half-month term, but "Net 14" or "due in 14 days" is perfectly clear if you print the date.

When you invoice across borders, state the currency, the exact due date and who pays bank charges, because international transfers can take several days to arrive.

Should you use 14 days or 30 days?

Choose 14 days if...	Choose 30 days if...
Your customers are sole traders or small companies	Your customers are large companies with monthly payment runs
You invoice frequently, weekly or fortnightly	You invoice once a month
You buy materials before you bill	Your costs are mostly your own time
Cash flow is tight	You have a cash buffer and want to win larger contracts

You can also mix them: 14 days as your standard, with 30 days offered to established business customers who have paid reliably for several months. Record each customer's agreed terms so your invoices are always consistent.

Consumers vs business customers

The late payment interest rules described above apply to transactions between businesses. If you invoice private individuals, such as homeowners, you can still set 14 day terms, but statutory late payment interest under the business-to-business rules does not apply. Any late fee for consumers should be agreed clearly in advance, be proportionate and comply with consumer protection rules. For consumer jobs, many tradespeople ask for payment on completion or within 7 days instead, often by card or bank transfer at the door.
