How quickly can I use the services of SIX Payment Services?

SIX Payment's verification process usually takes between 3-15 working days (not the same for every company). Any copies of identification documents, signatures or other documents required by the provider SIX Payment Services must be sent directly to for authentication, so that the verification procedure can be completed and the services can be made available.

Activate additional currencies

In order to activate other currencies such as "GBP" / "USD" / "EUR", please have the contracts sent to you by "Worldline | SIX Payment Services". Please send an e-mail for this purpose:



Accounting in bexio

Provided the customer pays via the bexio invoice under: "Pay Now", the transaction is booked via the default Account 1029 (Bank System Account). Please note that this information may differ because the account number can be changed as desired.

Recommendation: If the account number and the account name of this System Account are changed, the traceability for technical support is also made more difficult.

For this reason, we recommend that you do not make any changes to this account. If you have already made changes: Check the journal, after an automatic payment via a Worldline/SIX Payment Service, to see in which account it has been booked. 

Expense booking: You can manually enter any expenses by using "Manual postings". For further questions, please contact your accountant or financial adviser directly. (Find Accountant)
