You can see an outstanding or failed payment in the Workit app under Invoices. First check that the account number (IBAN) in your account is correct; an incorrect or changed account number is often the cause of a failed direct debit.
Everything correct and payment still not working? Contact us. We can send you a payment link so you can easily settle the payment. Note that with an outstanding payment, your account may be temporarily blocked until it has been paid.
