You can store an IBAN and its account holder per relation. Because an IBAN decides where money goes, not everyone may change it. An owner or administrator of the environment turns that right on per user.
Give a user the right
- Click your name at the top right and choose Users.
- Open the user.
- On the Details tab, tick May change relation IBANs and click Save.
The user gets the right as soon as they come back to Invoyz, without signing in again or refreshing the page. Untick it and click Save to take the right away.
Change the IBAN
- Go to Relations and open the relation.
- On the General tab, enter the IBAN.
- Click Save.
Spaces and lower case are fine; Invoyz stores the IBAN without spaces and in upper case. If the number is wrong, you see the message This is not a valid IBAN. Clear the field to remove the IBAN.
Without the right you can see the IBAN but not change it.
With the same right you can also enter the IBAN right away when you add a relation. When you add the relation from an invoice, Invoyz fills in the IBAN from the invoice when it recognises it. Check it before you save.
The account holder
Next to the IBAN is the Account holder field: the name the account is in. If you leave it empty, Invoyz uses the relation name, which you see greyed out in the empty field. Only fill it in when the account is in a different name.
You change the account holder with the same right as the IBAN, also when you add a relation. Without an IBAN, Invoyz does not store an account holder.
Automatic payment (Twinfield)
When you add a supplier in a company connected to Twinfield and enter the IBAN, the field Automatic payment appears. Choose None or one of the payment types from Twinfield. With a payment type, Twinfield can include the supplier's invoices in its payment list. If you leave the field on Not set, the supplier gets Twinfield's default setting.
You choose the payment type only when you add the supplier, with the same right as the IBAN. After that you change it in Twinfield. If Twinfield rejects the IBAN or the payment type, the relation is created without the IBAN and you see a message.
Sync with your accounting software
If the company is connected to Exact Online, Twinfield, Xero or Odoo, Invoyz fetches the relation's IBAN on every sync. The IBAN in your accounting software wins: an IBAN entered in Invoyz is overwritten when the accounting software has a different one. An account number that is not a valid IBAN is skipped. Exact Online, Twinfield and Odoo also pass on the account holder, which wins just like the IBAN. Xero has no account holder.
When you change the IBAN or the account holder in Invoyz, Invoyz sets them in the accounting software first and only then in Invoyz. If the accounting software rejects the IBAN, you see the error and the old IBAN stays. Clearing an IBAN in Invoyz does not remove it from the accounting software.
When you enter the IBAN while adding a relation, Invoyz first creates the relation in the accounting software and then sets the IBAN. If the accounting software rejects the IBAN, the relation is created without it and you see a message. Then enter the IBAN on the relation.
QuickBooks, Visma.net and SnelStart do not exchange the IBAN with Invoyz.
Who changed the IBAN?
Every change shows up in the Audit log as IBAN of relation ... changed or Account holder of relation ... changed, with who did it and when. You find the log under Settings and on a user's Audit log tab.
