Abacus
Your accountant books in Abacus, you write invoices in elektro.box. Between the two sits a file: a period's invoices, prepared so that Abacus reads them without rework.

In elektro.box
For a period you choose, elektro.box writes all invoices into an AbaConnect file. Your accountant reads it into Abacus with program 5534.
The file carries the document type, the client number if you want it, and the VAT codes your accountant uses for the 8.1, 2.6, 3.8 and 0 per cent rates.

A file, not an interface: nothing is read back from Abacus, and you match incoming payments in elektro.box from the bank statement.
