I get an error when paying by credit card. What can I do?

The most common payment error is a rejection on the side of the credit card provider for unspecified reasons, which results in an Transaction Not Allowed error. This message indicates that the bank will not approve this transaction. This does not mean that there is an issue with your credit card. Unfortunately we do not get more detailed information from the bank.

Typical reasons and solutions for this error:

A high level of activity on the credit card in a short time.
Waiting can help here. A payment the next day could resolve this error.

An incorrect card number or expiration date.
Check your entries and try again

Insufficient funds in the bank account or exceeding the card limit.
Make sure your account has sufficient funds or increase your limit.

The payment is rejected due to fraud filters of the bank
Enter as many data as possible. In particular, all address data as well as a company name if necessary. This very often leads to the solution of the problem!

Browser extensions such as ad blockers may cause communication with our payment system to not work properly.
Disabling such extensions or changing the browser can fix this error.

If you still have problems with the payment, you could pay alternatively with PayPal. We also offer purchase on account from our annual business accounts - please contact our support.
