IBAN/BIC

Bank Account - Basic Behaviour

The correct bank account can be used:

via the data stored in the Company screen of the MyBillit user interface.
or launched via the Json body in the supplier element.

Current situation : One bank account is used. This is the bank marked as default in MyBillit User Interface.

How this can be checked in the user interface:

Select One Bank Account per Invoice

Within MyBillit, multiple bank accounts can be defined. If each invoice should have a specific bank account, then this is possible.

Behaviour and Requirements for multiple bank accounts	Sandbox	Production
The bank account must occur in the list of Banks in Billit	yes	yes
The bank account must be verified (country code BE)	no	yes
1 IBAN and 1 BIC are specified in the Json file	yes	yes
When no IBAN or BIC is specified in the Json, then the default Bank account is included	yes	yes
Outgoing invoice : number of bank accounts included is limited to 1	yes	yes

In case of Factoring

Elements:

In case of factoring, the bank account to pay to is the account of the factoring company.

Current method used with API:

make sure that the bank account of the factoring company is in the list of the bank accounts
Bank account must be verified on production environment : this is via a manual procedure. More information : https://docs.billit.be/docs/verification-to-non-belgian-user . Section : Bank Account Verification on the Production Environment, Method 3. So you send mail to [email protected] . Information to include : 1) Environment : Production 2) Party ID of the company. 3) Clearly refer to the factoring scenario.
For invoices where factoring is applicable, include the factoring IBAN/BIC in the Json
Invoices are sent in einvoice network as standard invoices. In case of Peppol, the normal invoice type codes are use.
You can add in text field description about the factoring. E.g. in Json field comments (will also appear on human readable of Billit)

Below example were Comments and Payment terms are used to indicate use of factoring:

{
 "OrderType": "Invoice",
  "OrderDirection": "Income",
  "Comments": "Payment has been transferred to Bank XYZ Commercial Finance.  Invoice is to be paid on account of this bank.",
 "OrderNumber": "QS-0001KBC6",
 "OrderDate": "2025-11-26",
 "ExpiryDate": "2025-12-30",
 "IBAN": "BE20734054285956", // This is the IBAN that will be included for sending
  "BIC": "KREDBEBB", // This is the BIC that will be included for sending
 "CustomFields"  : {
  "PaymentTerms": "Payment has been transferred to Bank XYZ Commercial Finance.  Invoice is to be paid on account of this bank."
