Účtenkovník for freelancers and small business
Same app, different questions. Invoices from email, VAT breakdown, registry-verified company IDs and accountant-ready export are Premium — the free plan covers the rest.
One receipt
Everything we read off it
You photograph this. Účtenkovník works out the rest — every line item, the VAT recap, and the fact that “PILS URQ 0.5” is Pilsner Urquell.
What's on the paper
- 1 The store Name and logo.
- 2 The specific branch Not just the chain — the shop you actually visited.
- 3 Company registration Verified against the official registry.
- 4 Items, quantities, prices Every line on its own, discounts included.
- 5 VAT breakdown Rates and amounts for the receipt and each line.
- 6 Date and time What your charts and warranty windows are built on.

Four ways to add one
How a receipt gets into Účtenkovník
On paper, in your inbox, or nowhere at all — it ends up in the same place.
Photograph it or upload it
A paper receipt, a PDF invoice, or a screenshot from another app.
Read the guide-
PDFs and invoices
Store invoices, PDFs from your inbox, and scanned documents.
Forward them by email Premium
You get your own address to forward online-store paperwork to.
Read the guide-
Emails without attachments
Including order confirmations that arrive as plain text with no attachment.
Let your AI assistant do it
An MCP-capable assistant can add a receipt for you.
Type it in
When there's no document but you still want the expense counted.
Every route lands in the same archive
Processing is identical whichever way it arrived. A forwarded receipt looks exactly like one you photographed.
One product, many names
We don't transcribe a receipt. We read it.
Every store writes product names its own way. Until someone matches them up, prices can't be compared — and that matching is the work Účtenkovník does for you.

-
It counts everywhere
The converted amount flows into your charts and exports, not just the receipt.

What the data tells you
-
What got more expensive?
Product price history
Watch what your materials are costing you over time.
Go down to a single product: price history, average price, highest and lowest purchase — filterable by period or tag.
-
Where does the money go?
Spending over time
Week, month, year — where the money goes.
Track total spending over any period and how it moves. You see immediately which month jumped, and why.
-
What did that holiday really cost?
By tag
What a specific job actually cost.
What you don't have to do by hand
-
Recurring expenses
Office rent, software, insurance — without re-entering them.
Set a cadence from daily to yearly. Účtenkovník creates a copy each period, so the fixed costs you never get a receipt for still show up in your numbers.
- Backfill the history Set up a recurrence and fill in past periods too.
-
Data export Premium
Hand your accountant a CSV or XLSX.
-
Web app
The same account in your desktop browser.
Zespr is our web app — sign in with the same account you use on your phone and work with your receipts on a big screen.
-
AI assistant access (MCP)
Ask your assistant what a job cost — or have it fix a document.
Connect Účtenkovník to any MCP-capable assistant and just ask: how much did I spend on coffee last year, what got more expensive this month. It can add a receipt, correct line items, and manage tags too. Included in the free plan.
