Legend:
The table above only contains the most commonly-used banks in Belgium. Even if the customer's bank isn't mentioned, above, mostly likely it supports B2B mandates. To see the list of all banks that support B2B mandates, please refer to this webpage from the European Banking Association. Specifically, the Excel sheet at the bottom of the page.

In this case, electronic signing is not available. You can still create B2B mandates using the traditional paper-based method and upload the signed document to Twikey — see B2B paper signing for non-connected banks.
Alternatively, Twikey can confirm the bank registration for you automatically instead of you having to verify a document yourself — see B2B automated validation for non-connected banks.
