How do AI finance integrations actually work?

+

Cortena's agents sit between your invoice sources and your accounting system. Invoices arrive (email, bank feed, or cloud drive), Cortena extracts line items and matches them against your chart of accounts and cost centres, then pushes booking-ready entries into DATEV, Exact Online, or Twinfield — using your rules. You review and approve in your system.
