Frequently asked questions

Can I stop delivery for non-payment?

Yes, but only if this is stated in your terms and conditions. For ongoing services you may suspend the service after a written warning.

When does an invoice expire?

After 5 years for business clients, 2 years for consumers. The term starts on the due date of the invoice. So send reminders on time to prevent expiration.

Do I have to pay VAT on uncollectable invoices?

No, you can reclaim the VAT as soon as it is definitively established that the claim is uncollectable. You must be able to prove this with, for example, a bankruptcy declaration.
