What is pre-accounting? A guide for accounting firms

What exactly is pre-accounting?

Pre-accounting is the set of tasks that turns raw source documents into correct entries in the accounting software. Think of purchase invoices, sales invoices, receipts and bank statements that come in, are read, are assigned to the right general ledger account and VAT code, and are then linked to payments. Chasing missing documents and investigating unknown payments are part of it too, because a set of books is only correct once every transaction is explained.

The name says it all: it is the work that comes before the actual accounting. Only once pre-accounting is done can you prepare a VAT return, close a period, compile annual accounts or advise a client on figures that are correct. Errors or backlogs in this phase affect everything that follows. A wrong VAT code ends up in the return, and a payment that is not reconciled leaves an open item that in reality no longer exists.

Which steps are part of pre-accounting?

Pre-accounting consists of a fixed sequence of steps that repeats for every document, regardless of the client or the accounting software. In practice these steps often overlap, especially when documents arrive scattered over time or when information is missing. A receipt delivered weeks after the payment, for example, means the bank transaction sits unexplained on a suspense account for all that time.

The better these steps connect, the less work is left over at the end of the month or quarter. A closed process, in which each step directly triggers the next, prevents documents, bank lines and client questions from getting stuck separately from each other. That is also the starting point of modern pre-accounting software: not speeding up a single step, but connecting the whole chain from document to reconciled booking.

1. 1Collect: invoices, receipts and statements arrive via email, upload, app or a connected source.
2. 2Recognise: supplier or customer, date, invoice number, amounts and VAT are read from the document.
3. 3Code: each line gets a general ledger account, VAT code and, where needed, a cost centre or project.
4. 4Book: the entry is recorded in the administration's accounting software.
5. 5Match and reconcile: bank transactions are linked to the open items (afletteren in Dutch).
6. 6Ask: anything missing or unclear goes to the client as a question and is processed once answered.

Why does pre-accounting take firms so much time?

Pre-accounting takes a lot of time because it is mostly repetitive manual work that still requires attention. Every invoice looks different, clients deliver documents irregularly and every administration has its own agreements on ledger accounts, cost centres and VAT. Firms that serve many administrations switch all day between clients with different charts of accounts, industries and sometimes different accounting software, and have to remember how things are done for each one.

On top of that, knowledge often lives in people's heads. An experienced bookkeeper knows that one client's fuel receipts belong under travel expenses, but that agreement is not written down anywhere. If that colleague is away, or the firm grows, the knowledge has to be rebuilt. Client communication also tends to run through separate emails and phone calls, so nobody knows exactly what is still outstanding. Common bottlenecks are:

• Entering invoices one by one: supplier, ledger account and VAT code.
• Going through bank lines separately and reconciling them by hand.
• Emailing and calling clients about missing receipts and unknown payments.
• Peaks around VAT deadlines, when everything has to be finished at once.

What is the difference between pre-accounting and bookkeeping?

Pre-accounting is the preparatory part of bookkeeping: it makes sure all transactions are recorded correctly and completely. Bookkeeping in the broader sense also covers period closing, reviewing suspense accounts, the VAT return, annual accounts and analysing the figures. Pre-accounting supplies the raw material; the rest of the bookkeeping process builds on it and is only as reliable as that raw material.

For a firm the distinction is mainly practical. Pre-accounting is volume work that is well suited to standardisation and automation, because the same suppliers, costs and payments keep coming back. Review, compilation and advice, on the other hand, require professional judgement and knowledge of the client. The less time preparation takes, the more capacity is left for the work clients actually value and where a firm makes the difference.

How does AI change pre-accounting?

AI changes pre-accounting from data entry into review. Instead of an empty entry screen, you get a booking proposal in which supplier, ledger account, VAT code and cost centre are already filled in, based on the history of the administration. You check the proposal and adjust where needed, rather than looking up and typing every field yourself. Corrections are remembered, so the next proposal for the same situation is better.

The difference from older automation lies in the approach. Template-based systems read fixed positions on a PDF and break when the layout changes. AI looks at context: previous bookings, corrections, supplier behaviour and master data from the accounting software. Every proposal gets a confidence score, so you decide what may be booked automatically and what a person should see first. That way responsibility stays with the firm.

How does pre-accounting work with Autoboeker?

Autoboeker is an AI platform that automates pre-accounting on top of your existing accounting software. You keep working in Exact Online, Twinfield, SnelStart or e-Boekhouden; Autoboeker prepares or processes invoices, bank lines and client questions, and writes the result back to the software. Ledger accounts, VAT codes and contacts are synchronised from the software and, together with the history, serve as context for every booking proposal.

The price is €50 per month for the whole firm, including 200 bookings and unlimited administrations, users and client portal. After that you pay €0.20 per extra booking, where a booking is one processed invoice or receipt that is posted definitively to the accounting software. You can cancel monthly and there is a 30-day money-back guarantee. The parts of the process are:

• AI recognition of invoices and receipts without templates.
• Automatic booking above a confidence threshold that you set.
• AI bank matching with automatic reconciliation for Exact Online, Twinfield and SnelStart.
• Client questions (vraagposten) sent automatically, answered in the client portal or app.
