When you have an outstanding invoice with a debtor, you are allowed to add interest to the balance as soon as the invoice becomes overdue.

However, you cannot simply add any figure to the original amount. The interest rate you can charge will depend on the location of your debtor and the age of the invoice.

Applying interest rates

If, for example, your debtor is based in the Czechia and has only just gone over the payment date, then you can apply the current interest rate. However, interest rates are revised every 6 months in January and in June. Therefore, if your invoice became outstanding in July last year, you may need to apply 2 interest rates to the unpaid balance.

How to work out what should be applied and when

Thankfully it is not too difficult to find out what interest you should apply and when. There are many calculators available online to help with this task. To ensure you are using the must up to date information though, use a reputable site. We recommend the European Union website.

Debt recovery costs on late payments

There are other debt recovery costs that you can charge to your debtor. Again however, these are very different depending on the country of your debtor. For example, in the UK, compensation costs can be added depending on the amount of debt:

Amount of debtDebt recovery charges
Up to £999.99£40
£10,000 or more£100

Inform your customer 

If you decide to apply compensation costs and interest, you should of course inform your customer by supplying them with an updated invoice that details the extra costs and highlights the new outstanding balance.
