AI bookkeeping for VC funds and family offices.
When you run on many entities, the books lag weeks, because payables wait on a tax advisor or a freelancer. Cortena keeps accounts payable real-time for every entity: routed, coded and ready to pay in the right one.
Multi-entity by design · DATEV, Exact Online and Twinfield per entity
Ten entities, one part-time bookkeeper, books that lag weeks.
A group like yours runs on many entities, each with its own ledger and its own rules. Accounts payable automation was never built for that shape. So the work lands on people.
Entity sprawl
Every deal adds an entity. Every entity adds a ledger, a chart of accounts and a stream of invoices that has to land in exactly the right place.
External dependency
Payables sit with a tax advisor or a freelancer who books in batches. Your books are only as current as their last visit.
Weeks of lag
Management fees, legal bills and deal costs pile up unbooked. By the time the batch is processed, the position you report is weeks old.
One inbox in. The right entity out.
Cortena is accounts payable automation built for multi-entity structures. Invoices arrive in one place and land in the right ledger, coded by that entity's own rules and ready to pay.
One inbox for the whole structure
Forward every supplier invoice to a single address, or let each entity keep its own. Root-mailbox routing sorts the rest, so nobody plays traffic controller.
Routed to the right entity
Cortena reads the bill-to name, address and VAT ID and assigns the invoice to the right entity. Ambiguous invoices are flagged for a person, not guessed.
Booked by that entity's own rules
Each entity keeps its own chart of accounts, cost centres, VAT logic and approval flow. Each one books by its own rules. Rules never leak between entities.
Payments prepared in the right entity
Payment proposals are created in the entity that owes the money, against that entity's bank account, and wait for sign-off. No more paying one entity's invoice from another.
Real-time books, without the headcount.

It reads the bill-to name, address and VAT ID on the document and matches them against your entities. When an invoice is ambiguous, it is flagged for a person to confirm, not guessed. Confirmed routings become precedents, so accuracy improves with your structure.
Yes. Every entity keeps its own chart of accounts, cost centres, VAT logic and coding guidelines. SKR04 comes preloaded for German entities, and rules never leak from one entity into another.
Yes, per entity. A German entity can post to DATEV while a Dutch entity posts to Exact Online or Twinfield. Each entity exports booking-ready batches to its own system, with the source document attached to every entry.
Your rules decide. Approval workflows are set per entity and can be inherited from the group, so a managing director signs for one entity while deal leads sign for theirs. Nothing posts without sign-off, and every approval is logged.
Booking-ready entries, per entity, in their own system. Instead of a folder of PDFs, they get coded batches with the document attached to every entry, exported to DATEV, Exact Online or Twinfield. They review and finalize instead of keying.
