Invoice Payment Terms UK: What to Include and How to Get Paid Faster

Late payments cost UK small businesses billions every year. Setting clear payment terms — and knowing your rights — can dramatically improve your cash flow.

What Are Payment Terms?

Payment terms tell your clients when they need to pay. They set expectations upfront and give you legal backing if payment is late.

Without clear terms, you have no grounds to charge interest or take action on late payments.

Common Payment Terms

For small businesses, Net 14 or Net 30 strikes a good balance between being fair and protecting your cash flow.

What to Include on Every Invoice

Your invoice should always show:

• ✓ Your business name and address
• ✓ Client's name and address
• ✓ Unique invoice number
• ✓ Invoice date
• ✓ Clear due date (not just "Net 30")
• ✓ Description of goods/services
• ✓ Amount due including VAT
• ✓ Your VAT number (if registered)
• ✓ Payment methods accepted
• ✓ Bank details for BACS

Pro tip: Write "Please pay by [specific date]" instead of "Net 30". It's clearer and harder to ignore.

Your Legal Rights

Under the Late Payment of Commercial Debts (Interest) Act 1998, you can:

If the base rate is 5%, you can charge 13% annual interest from the day after the due date.

Claim Compensation

You can include these terms on your invoices to make them enforceable.

6 Ways to Get Paid Faster

Don't wait until month-end. Send invoices the moment work is complete.

2. Make Payment Easy

Offer multiple options: bank transfer, card payment, online payment links. The fewer barriers, the faster you're paid.

3. Use Clear Language

Don't write "Net 30". Write "Please pay £500 by 15 February 2026".

4. Send Reminders

Automatic reminders work. Send one before the due date, one on the day, and one after.

5. Offer Early Payment Discounts

A 2% discount for paying within 7 days can transform your cash flow.

6. Take Deposits

For large projects, request 30-50% upfront before starting work.

When to Review Your Terms

Consider changing your payment terms if:
