Outbound · One-file apps
Outgoing invoices: check before the invoice goes out.
Check your own e-invoices before sending them: are the identifiers right, does the invoice add up, and will the recipient accept it? The outbound bundles read, check and keep track of your invoices, with the official KoSIT validator or with Mustang if you like.
This way an error shows up with you and not with your customer.
