Data flow

What runs through these connections

Every integration on this page hangs off the same path: an event from your product goes in, an auditable invoice with net, VAT and gross comes out, and it lands in your accounting after that.

One event format for every source: payment providers, your own backend, imports.
Tax logic runs before the invoice, not as a correction after it.
The same invoice leaves as XRechnung, ZUGFeRD and a DATEV export.
