Do we have to change accounting software?

No. It stays the accounts, with every year still inside it — Kontoo reads the structure it finds and writes into it.

Which software does Kontoo write into?

Primavera, with a complete integration running in production. The posting engine is Kontoo's and sits apart: everything specific to Primavera lives inside the piece that talks to it, and nowhere else.

How does it reach the client's instance?

Through that instance's own programming interface, with the credentials the practice sets in Settings and from the addresses the client authorises on their installation.

Do the entries look like ours?

They land in the chosen journal, with the accounts from your rules and VAT by rate. Nobody tells them from one written by hand. A supplier that does not exist yet is opened with the numbering that company already follows.

And what Kontoo cannot post?

It stays unposted, with the blocker written down. Before writing anything at all, Kontoo validates what it can: debit equal to credit, accounts that exist, an open period — and a batch is a record with period, count and total that can be reversed in full.

Bookkeeping

The bookkeeping is Kontoo's. The accounting software is where it lands.

Documents come in, entries go out — and appear in the client's software with the right journal and the right number, as if they had been written by hand. Nothing migrates and nobody transcribes.

Zero migrations: The chart of accounts, the counterparties and the journals stay where they are.
121 of 127: The rules come out of the company's own history, with the count in plain sight.
23% + 6%: Bases and VAT split by rate, from the document's QR code.
It never guesses: What is not certain stays unposted, with the reason written down.

What it does

Six things that stop being somebody's job

All of them say what they did. All of them stop when they stop being sure.

It connects to the client's instance

Chart of accounts, counterparties, bank accounts and journals come in. Repeatable, with nothing duplicated.

It learns from the history

If a supplier always went to the same account, that is the proposal — with the count.

Rules written in words

“Energia Atlântico invoices go to 6241 and are paid by transfer.” That indication is enough.

VAT balances by rate

Bases and tax split by rate, from the document's QR code where there is one.

It writes, and reads back

It shows what is really in the accounts, and not the record of what was sent.

It never posts in doubt

A VAT class missing? It stays unposted, with the reason in plain sight of whoever resolves it.

Whoever opens the accounting software in the morning does not need to know Kontoo exists.

They find everything where they expect it: right journal, right number, right accounts.

How it works

The life of a document, from the start to the accounts

Multiplied by a few hundred a month, with nobody looking at most of them.

It arrives

By screen, by camera, by email, or from e-Fatura and the SAF-T export.

It is identified

Counterparty, tax number, amounts and dates, with the counterparty matched by tax number and never by name.

It becomes an entry

The rules decide the accounts, and the conditions split the base where they have to.

It enters the accounts

One document at a time or in bulk — and the automatic shift does this on its own.
