Retyping details from the invoices and receipts you receive is slow and error-prone. NaFakturu can recognise documents automatically with AI (OCR): just take a photo of the document or upload it, and the system pulls out all the important details by itself. This guide shows you how.
Tip: For the best results, take a good-quality photo or scan of the document. It should be straight, well lit and not folded. AI can cope with a slightly tilted picture, but a clean image greatly improves accuracy.
What you will need

- A document to scan: an invoice, receipt or other tax document as a photo (JPG, PNG) or PDF
How to scan
Open the expenses section
Sign in at nafakturu.cz and click “Náklady” (Expenses) in the main menu. You will see an overview of the documents and expenses you have received.
Upload the document
At the top of the page, you will find the “Načíst doklad” (Load document) button. Click it to open the upload dialog, then choose a photo or PDF from your computer. On a phone, you can take a picture of the document with the camera straight away.
AI recognises the details
Once the file is uploaded, AI starts analysing the document. Within a few seconds it usually recognises the supplier’s name, company ID (IČO) and VAT ID (DIČ), the document number, the issue and due dates, the individual items with prices and the total including VAT.
Check the recognised details
The system shows a form pre-filled with the recognised data. Go through all the details, especially the amounts, dates and supplier identification. If AI does not find the supplier among your contacts, it automatically looks up their details by IČO in ARES (Czech business register) and offers to create a new contact.
Confirm and save
When all the details are correct, click “Uložit” (Save). The expense is saved to your overview and you can come back to it at any time. The original scan stays attached to the record.
Important: AI recognition is very accurate, but not infallible. Always check the recognised details before saving, especially for documents with unusual formatting, handwritten receipts or poor-quality scans.
Frequently asked questions
Which file formats can I upload?
You can upload photos in JPG and PNG format and documents in PDF. The maximum file size is 10 MB.
Is there a limit on the number of scans?
The basic plan includes a limited number of AI scans per month. The PRO plan has a much higher limit. You will find the current limits in your account settings.
What if AI does not recognise the supplier?
If AI does not recognise the supplier’s IČO, you can enter it by hand. The system then tries to load the details from ARES. You can save the new supplier to your contacts right away. Find out more in the guide How to manage contacts.
