Why does the LIR Portal show that the invoice is still outstanding when I have paid?
It usually takes one business day before credit card payments are processed. It can take up to one week before bank transfers are processed.
It could also be that the RIPE NCC is unable to identify your payment due to an unclear or missing payment reference. This is why you should always provide your customer and invoice numbers as the payment reference.
To remove any doubt, you should always send a proof of payment to the RIPE NCC billing department with all the relevant payment details (bank account holder’s account number, bank account holder’s name, transaction reference, date of transfer and amount transferred) as well as the invoice number.
