Book invoices in Moneybird, with the payment status coming back.
Built, but not yet tested against the real service. It is switched on only after that test.
Still needed: a test in a Moneybird test administration.
You connect your administration with your own Moneybird login. A sent invoice is booked there on the right contact, and once it is paid in Moneybird, it shows as paid in Trajenda too.
