Verified intercompany transactions

Your books should reconcile themselves.

enneakis turns every transaction between your entities into one record both sides confirm and sign, once. No more chasing the other entity, no more month-end matching, no more “your number doesn’t match ours.” The confirmed entry flows straight into both ledgers, tamper-evident and audit-ready.

The problem

The hours you lose every close

One transaction, two sets of books, two versions of the truth. Reconciling them between entities is manual, repetitive, and expensive.

01 Intercompany mismatches Entity A booked it one way, Entity B another. Someone spends days each close finding the gap.
02 Endless confirmation chasing Every close you re-confirm balances by email and spreadsheet, entity by entity, just to agree on what already happened.
03 Audit scramble Pulling evidence after the fact: approvals, confirmations, who agreed to what and when.
How it works

How enneakis works

A confirmation layer on top of the systems you already use. You don’t replace your bookkeeping. You make each intercompany transaction undeniable.

1

Record the transaction

An intercompany transaction is entered once, from your existing system or a simple form.

2

Both entities confirm

The other entity reviews and signs the same record. One signed receipt, shared by both, not two guesses.

3

It exports, locked

The confirmed, tamper-evident entry flows into both ledgers. Reconciliation is already done, and the audit trail builds itself.

The payoff

What it gets you

Reconciliation work drops sharply

When both entities reference one signed entry, there is little left to match at close.

Disputes end before they start

A signed confirmation is the evidence. No more “we never agreed to that.”

Continuous, tamper-evident audit trail

Every confirmed transaction is locked and provable. Audit prep stops being a fire drill.

Faster close

Less manual matching means days back every close for your finance team.

The mark

Books that carry a mark of trust

Using enneakis is itself a signal. Every intercompany entry leaves your books with your own verifiable seal: the kind of rigor partners, boards, and auditors notice.

  • To your auditor: entries arrive confirmed and signed, evidence instead of assertions.
  • To your board and banks: a visible standard of control, not a promise on a slide.
  • To the other entity: one shared, signed truth that no one can quietly rewrite.
Who it’s for

One source of truth, for every role in the numbers.

Whether you post, consolidate, or oversee: reconcile without noise, in one shared language.

enneakis is built by Stefan Verhagen, drawing on 40+ years in accounting and automation: a drs. in Informatics from Radboud University Nijmegen and an MBA from Cornell University. He has built bookkeeping software before and understands both the finance close and the cryptography beneath it, so the product solves the controller’s headache, not a technology thesis.

FAQ

Questions

The things finance teams ask us first.

Do we have to replace our accounting software?
No. enneakis sits on top of what you use and exports confirmed entries back into it.
What makes the record tamper-evident?
Each confirmed transaction is cryptographically signed by both entities and locked, so it can’t be altered after the fact without detection.
Does the other entity need an account?
It’s lightweight. The other entity confirms and signs through a simple flow, with no heavy system to adopt. Because both entities sit under one group, roll-out is a policy decision, not a sales process.
Is our data shared with anyone?
No. Each entity confirms only the specific transaction between you, not your wider ledger. Your data stays yours.
Which accounting systems do you export to?
We start with the system your pilot runs on and export confirmed entries back into it. Tell us your stack (Exact, AFAS, NetSuite, and others) and we’ll confirm fit.
