B2B digital signing for connected banks - Belgium

Tags:agreementsb2bbelgiumelectronic-signingdigital signingconnected bankseiditsmebank card

Not all Belgian banks support electronic signing for B2B mandates through Twikey. This page provides an overview of available signing methods per bank. If your customer's bank is not listed below, you'll need to use the paper-based signing method.

How it works

When a bank is connected to Twikey's electronic signature solution:

  1. Your customer signs the B2B mandate using one of the available electronic methods
  2. The agreement appears in your Twikey dashboard with status 'Awaiting bank approval'
  3. The bank reviews the mandate (this typically takes between 5 minutes to 2 business days)
  4. The status changes to either 'Signed' (approved) or 'Cancelled' (rejected by the bank)

Supported banks and signing methods

The table below shows which electronic signing methods are supported by each Belgian bank:

Bank not listed?

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.
