## Invoice extraction: reads, recalculates and checks every document

Take an invoice for office supplies, for example. Before you see it, AI has read the details from it, and the program has checked that the numbers add up and the supplier is in order. You just confirm the entry.

- ### One queue for all documents

    A photo from your phone, an email attachment and a file uploaded to the website all end up in one place. For each document you see where it came from and from whom, and you can scan a multi-page contract with your phone as a single file.
- ### Reads the text and recognizes the document type

    It gets the text from a photo or scan and recognizes whether it is an invoice, receipt, delivery note, contract, report or business card. Then it extracts exactly the details that belong to that type.
- ### Shows how confident it is

    Each detail shows how confident the recognition was, and on a scan the place the value came from is highlighted. Where it is not sure, the field is marked.
- ### The program calculates, not AI

    Totals and VAT are recalculated by a standard program using fixed rules. It also recognizes when the same document has already arrived and catches the duplicate before it is saved.
- ### Checks the supplier

    The program checks the company in ARES, whether the supplier is an [unreliable VAT payer](https://otrock.cz/en/blog/unreliable-vat-payer) and whether the account you are to pay is published. It warns you about a suspicious document before you pay it.
- ### Enters data where it belongs

    A confirmed document is saved to the register by its type: invoices with invoices, contracts with contracts. Its details also go into your accounting program.

## Send and confirm; the helper works in between

The whole path of a document from photo to entry in the accounting program. For each step it is clear who does it.

1. ### Send the document

    Forward the invoice email, photograph the receipt with your phone and send it to Telegram, or upload the PDF on the website. Send several pages of one document at once.
2. ### AI reads and recognizes

    Turns the photo into text, recognizes what kind of document it is, and fills in its details, including the individual line items.
3. ### The program checks

    Recalculates totals and VAT, looks for duplicates, and checks the company in ARES and in the VAT payer register.
4. ### You confirm

    Review mainly the details marked as uncertain, or correct them directly in the field, and confirm saving from your computer or phone.
5. ### The data is in the register and in accounting

    You find the document in the register among documents of the same type, and its details are already in your accounting program.

## One photo at the till instead of evening retyping

### Before

- Receipts pile up in wallets, in cars and in mailboxes
- Invoice details are retyped by hand into a spreadsheet in the evening
- A typo in an amount is found only at year-end closing
- Nobody checks the supplier's reliability or its account

### With a helper

 Done

- You photograph the document as soon as you get it
- AI reads the details and you just confirm them
- The program catches a wrong total at once
- Supplier and account checked before payment

## Helps whether you or the whole team handle documents

Every company has documents. What differs is how many there are and how many people bring them in.

### Sole traders and tradespeople

You photograph receipts and invoices as they come in, for example right in the car after a purchase. The accountant then gets everything together and already read.

### Small businesses

Anyone who receives documents sends them on, and you see who they came from and what is still waiting for confirmation. An invoice does not stay in a colleague's mailbox.

### Medium-sized businesses

Supplier invoices arrive in several mailboxes and more people handle them. Each document type has its own register, the program checks duplicates and suppliers for all of them, and only what is truly uncertain goes for checking.

## No need to change your accounting program

Confirmed details go into the program you already work with, and you send documents by whichever channel is closest to you. The program checks the supplier against ARES and the VAT payer register. You choose the AI model that reads the documents in the admin, and it can be a different one from your other helpers.

## FAQ about invoice extraction

You will find more answers in the list of all questions.

 [All questions](https://otrock.cz/en/faq)

What is invoice extraction?

Extraction means you do not retype the details from an invoice or other document by hand. AI reads them from a photo, scan or PDF, the program recalculates the amounts, and they are saved to the register only once you confirm them.

What documents can extraction read?

Besides invoices and receipts, also delivery notes, contracts, reports and business cards. It recognizes the document type by itself, and for each type it is set which details are read and which register they are saved to.

What if AI reads a detail wrongly?

You see how confident AI is for each detail, and uncertain fields are sent for checking. You correct them directly in the field, and the program recalculates totals and VAT after the correction. Nothing is saved without your confirmation.

Do I need a scanner?

No, a phone photo sent by email or to Telegram is enough. Your phone can even handle a multi-page scan, and a finished PDF from your computer can be uploaded on the website.

Does it transfer data to our accounting program?

Yes. After you confirm, the details are entered into your accounting program, such as Pohoda, Money or Fakturoid, and they also stay in the document register. Nobody has to retype them, and the accountant receives data that has passed the program's checks.

Can colleagues also send documents?

Yes, the whole team can send documents, each from their own phone or email. The document shows who sent it, from where, and whether it has already been confirmed.

How much does invoice extraction cost?

It depends on the scope: which systems we connect it to, for example your accounting program, and where it runs. You will hear the specific price in the free consultation, once we have seen your documents.

In practice

 Live since August 2026## Trailer certificates from photos for Dva Kraje

A company that helps Polish entrepreneurs do business in the Czech Republic, among other things with vehicle registration.

For the company, we built a register of its clients' trailer registration certificates. AI reads the details from a photo of the certificate, staff check them, and the program then monitors vehicle inspection (STK) validity and sends a reminder in time.
