Auguria has developed a module that lets you choose which IBAN is displayed on customer invoices, so that bank flows can be split when the company has several bank accounts.
Company record
To assign a bank account on the company record, go to "Configuration → Users & Companies → Companies"
On the company record, the "Bank Account" field lists the bank accounts linked to the target company.
The bank account set on the company record will be assigned by default to each newly created contact record (not to existing ones, so for those you need to do an export/import)
Contact record
On the Accounting tab of the Contact record, the "Payment Account" field defaults to the bank account set on the company record
Invoices & credit notes
