The deterministic close

Your books, always closed.
Every number, provable.

Klopt does the arithmetic with deterministic software: the same answer every time. The AI reads every entry and tells you what looks off, but it can’t change a number. Anything that needs judgment goes to a person. When an auditor asks where a number comes from, the answer is already in the ledger, not lost in an afternoon of digging.

The AI never touches the numbers.

Sound familiar?

Bookkeeping should not cost you your confidence.

  • Close that never ends

    Month-end turns into a week of chasing spreadsheets, and you still are not sure the number is right.

  • AI you cannot audit

    A model quietly writes entries, and when someone asks “why this number?” there is no answer.

  • Audit season dread

    The evidence lives in inboxes and files, so every audit is a scramble to reconstruct what happened.

  • Data you do not control

    Your financials sit in someone else’s cloud, and you cannot say who can see them or what they train on.

Two ways to work with Klopt

One engine. Two ways to work with it.

Some teams want their books kept for them. Others already have a finance function and want sharper tools. The same deterministic engine runs underneath both. The AI never touches the numbers.

For 2–50 people

Klopt Bookkeeping

The books, done for you.

In early access, we run your bookkeeping end to end: postings, bank reconciliation, VAT and filings as we roll out. On top, controller-grade insight, so you get the discipline of a finance team without the hire.

  • The monthly close handled for you
  • VAT and filings handled as we roll out
  • Controller-grade reporting, policies and finance SOPs as we roll out
For teams with a finance function

Klopt Software

The engine, in your team’s hands.

In early access, your team works on the same engine, tuned to your policies, thresholds and KPIs. You get live numbers, an AI you can question, and audit-ready journals you can reperform at any point in time.

  • Automation shaped to your policies and internal controls
  • Live data with an embedded AI you can question
  • Audit-ready journals, reperformable at any time

One core under both

  1. Deterministic rules post every journal.

  2. An independent AI reviews all output and can never post.

  3. A person approves only the exceptions, bound to the exact entry.

  4. Every figure keeps a full audit trail.

Both are in early access and roll out progressively. We will tell you exactly what is ready today and what is still on the way.

Why it works

The approvals come first. The AI works inside them.

Klopt is built so that being right is the default, and so that anything unusual surfaces to a person instead of disappearing.

One way in, no side doors

Your books change in exactly one place: a deterministic rule or a person’s approval. Nothing else gets in.

AI that reads, never writes

An independent reviewer checks every posted entry and raises what looks wrong. It can suggest, it can explain, and it can never post or approve.

A human decides

Anything non-deterministic that changes a record waits for a person. Approvals are tied to the exact entry approved, so nothing is approved by accident.

Every number has a receipt

Each figure can be traced and re-derived later. Ask “why is this the number?” and the answer is there, not in someone’s spreadsheet.

No guesses, ever

Missing rates, undefined periods or unset policy produce a clear message, never a silent default and never an invented number.

Always closed, not month-end

Because the work is controlled as it happens, closing is a confirmation rather than a scramble in the last week of the month.

Always

audit-ready

Your books are in a state you can hand to an accountant or auditor on any day, not just after a project.

Zero

black-box postings

No number appears in your ledger that a person did not approve or a rule did not deterministically produce.

Days

to a confident close

The close becomes a short review of exceptions instead of a rebuild of the month.

How it works

From a posting to a proof, in three steps.

One way in

Every entry enters through a single controlled path: produced by a deterministic rule, or approved by a person. Nothing slips in beside it.

AI reviews, never writes

A read-only reviewer checks what was posted and raises anything that looks wrong. It can explain; it cannot change.

A person decides the exceptions

Deterministic rules post on their own. Anything not covered by a rule comes to a person, and the approval binds to the exact entry, so “why is this the number?” still has an answer later.

Trust & data

Your data is yours. Full stop.

You should never have to trade your data for good software. Klopt is built so your books stay yours: stored in the EU, read-only to an AI that cannot change them, and used only to keep your books.

EU

Hosted in the EU

Your data lives in European data centres, under European data-protection rules.

Never sold, never shared

Your financial data is not a product. It is never sold or handed to third parties.

Never used to train third-party models

Your books are never used to train third-party AI models.

Access you control

Only you and the people you authorise can see your data. Access is logged and limited to those people.

Yours to take

Export your data whenever you want, in a portable, standard format. No lock-in, no hostage situation.

Privacy by design

GDPR is the baseline, not an afterthought. Delete or export on request, any time.

Built for control

AI assists. People decide. Your books stay honest.

Klopt uses AI where it helps, such as reading documents, spotting oddities and explaining what changed, and keeps it firmly away from the numbers.

  1. 01Every entry is either produced by a deterministic rule or approved by a person. Nothing else reaches your books.
  2. 02The AI reviews everything and can never post or approve.
  3. 03Every figure can be traced back to why it is that number.

Questions

The things people ask before they trust us.

Still unsure? Ask us directly. A person, not a bot, will answer.

Klopt is an accounting platform built around a simple promise: your books are always closed, and every number can be proven. It combines deterministic bookkeeping with an AI reviewer that can read and suggest but never change your records.
