Contract payment terms detail when and how you expect to be paid for goods or services sold, including the payment due date, currency and acceptable payment methods.
Clear invoice payment terms are essential in any well written invoice². It’s good practice to discuss payment terms with the customer prior to the invoice processing, so there are no surprises - but backing up your negotiation with an easy to understand line on your invoice can help avoid misunderstandings down the line.
If you don’t add payment terms into your invoice, the default will usually be that your client is obliged to pay within 30 days³. However, you can negotiate different terms upfront if you'd prefer, as long as they’re detailed in your invoice.
If your client does not pay by the agreed payment date, you have a number of legal options including charging interest as a penalty⁴. However, most payment issues are better solved by clear communication, which can also strengthen your relationship with the client - threatening penalties should only be used as a last resort.
As we’ve already seen, you can negotiate the payment terms and due date that you prefer with your client, as long as it’s all clearly detailed when it comes to billing. However, it helps to understand the most common payment terms for businesses in the UK, as these will be what your client is used to working with.
The most commonly used payment terms in the UK include:
- PIA - payment in advance
- Net 7 - payment due 7 days after the invoice date
- Net 30 - payment due 30 days after the invoice date
- Net 60 - payment due 60 days after the invoice date
- Net 90 - payment due 90 days after the invoice date
- EOM - payment due at the end of the month in which the invoice was sent
Bear in mind that when invoicing international customers it is important to also understand the country specific business culture and standards - these could be quite different to the UK. Talk through your payment options and preferences with your client early on in your relationship - this is a professional approach, and can avoid issues later.

You can add in your payment terms to your invoice in a number of ways. If you’re using invoicing software or a template you’ll usually find a line to customise this information. If you’d prefer to create your own invoice manually you can do that too. In this case, a simple solution can be to include a panel detailing the payment terms at the top of the invoice, before you list out your itemised billing which can be used to check the full payment amount.
Billing in multiple currencies? You can do that easily with Wise Business, a non-bank provider that offers international business account with invoicing tool.

Encouraging prompt payment is a delicate balance, but several strategies can help without causing friction. Consider offering a small discount for early payment, such as a 2% reduction if the invoice is settled within 10 days. You can also make paying easier by using modern invoicing software with integrated payment links, like Wise Business, for instant card or bank payments. Clear, polite, and automated payment reminders also help keep your invoice at the top of your client's to-do list.
Yes, when invoicing internationally, your payment terms should be even more explicit to avoid confusion and delays. It is crucial to state the currency the payment must be made in (e.g., GBP, EUR, USD) to avoid disputes over exchange rates. You should also clearly specify the accepted payment methods and outline who is responsible for covering any international bank transfer or currency conversion fees, as these can be significant.

To minimise the chance of disputes, your terms need to be unambiguous and comprehensive. Include a clause detailing the process for raising a query about an invoice, including a specific timeframe (e.g., "Any queries regarding this invoice must be raised within 7 days of receipt"). You should also inform the consequences of non-payment, referencing your right to charge statutory interest on overdue amounts as a final deterrent.
Clear payment terms backed up by good communication will mean getting paid on time every time is easier. Use this guide to get started, and don’t forget to check out Wise Business as a smart way to allow foreign customers to pay you conveniently in 8+ currencies.
