When dealing with large companies as subscribers, you may encounter situations where the subscriber has multiple accounts (subscriber numbers) in Iteras. This can happen when deliveries are made to different addresses, and possibly also invoicing is done to different addresses (e.g., departments that need to approve the invoice). However, the subscriber still chooses to pay all invoices collectively – across their various accounts in Iteras.
This may involve credit notes from one account being applied to another. For example, if an invoice of DKK 1,000 has been issued, the customer may only pay DKK 700 because there is a credit note of DKK 300 on another of the customer's accounts. The credit on the other account frees up DKK 300, which then needs to be transferred and registered as a payment on the account where the amount was originally missing.
