Inside the app
Ready for your country
Poland
NIP and REGON, “Faktura VAT” wording, numbering like FV/1/10/2026, the small-business exemption note, the split-payment (MPP) note suggested from 15 000 zł — and KSeF built in.
Germany and Austria
USt-IdNr. and Steuernummer (UID-Nr. in Austria), German invoice wording, numbering like RE-2026-001 and the Kleinunternehmer note of each country.
Netherlands, Sweden and France
Btw-id and KvK-nummer, momsregistreringsnummer and organisationsnummer with “Godkänd för F-skatt”, N° TVA and SIRET with the 40 € recovery-fee line — each with its own VAT wording and numbering.
United Kingdom and Ireland
VAT number with company number (UK) or CRO number (Ireland), English invoice wording, “Not registered for VAT” when you charge none, in pounds or euros.
The invoice language does not depend on the app language: use the app in Polish and invoice a German customer in German — or the other way round.
Polish KSeF built in
In Poland invoices between businesses go through KSeF, the national e-invoicing system. UZYTAK Faktura sends them there itself — you only need your own KSeF token.
Your own token
Generate a KSeF token in the Ministry of Finance’s Aplikacja Podatnika and paste it into the app. It is stored encrypted on your phone.
Send with one tap
The app builds the e-invoice (XML) from your invoice and sends it to KSeF directly, without any server in between.
KSeF number and QR on the PDF
After acceptance the KSeF number and the verification QR code are printed on the PDF you send to the customer.
UPO and XML kept
The official receipt (UPO) and the XML stay with the invoice — and go into the month ZIP for your accountant.
Invoices for private customers (B2C) may be issued outside KSeF. In this version invoices are sent to KSeF in złoty (PLN) only.
Everything a small business invoice needs
Customers and items remembered
Type a customer or an item once — next time pick it from the list, with address, tax ID and price.
VAT done right
VAT per rate with a correct summary table. Not a VAT payer? The small-business exemption note is printed instead.
Reverse charge and MPP
Reverse charge with the right wording in the invoice language. In Poland the app suggests the split-payment (MPP) note from 15 000 zł.
Quote → invoice
Send a quote first; when the customer agrees, turn it into an invoice with one tap.
Paid and unpaid
Mark invoices paid and see per month how much has been invoiced and how much is still unpaid.
Send anywhere
Share the PDF by email, WhatsApp or any app on your phone — or print it.
A PDF your customer and accountant understand
Every invoice and quote becomes a clean A4 PDF on your phone:
- seller and buyer with the tax IDs of their country
- items with quantity, unit, net price and VAT rate
- a VAT summary per rate and the amount due
- bank account, payment terms and your own footer
- in Poland: KSeF number and verification QR code
PRO The month ZIP for the accountant — all PDFs, an Excel/CSV register and the KSeF XML and UPO — is part of Pro.
How it works
Set up once
Enter your business details, pick your country template and, in Poland, add your KSeF token.
Write the invoice
Pick the customer and the items — or turn a quote into an invoice. The totals and VAT are counted for you.
Send the PDF
Share it by email or WhatsApp; in Poland send it to KSeF as well. At the end of the month send your accountant the ZIP.
What the app does not do — yet
- It is not tax advice: check with your accountant what your invoices must contain.
- No XRechnung or ZUGFeRD files. A PDF invoice is still allowed in Germany for private customers, for Kleinunternehmer and, depending on turnover, between businesses until the end of 2026 or 2027.
- No sending to the Italian SdI — in Italy use it for quotes and pro forma invoices.
- No Spanish VeriFactu, no Peppol and no French e-invoicing platforms.
- No ROT/RUT deduction on Swedish invoices yet.
- KSeF invoices in złoty (PLN) only in this version.
We would rather say it plainly than sell you something that does not fit.

Questions and answers
Is UZYTAK Faktura really free?
Yes. You can issue 3 invoices a month and unlimited quotes for free, with every invoicing feature and KSeF sending. Free PDFs carry a small “UZYTAK Faktura · uzytak.com” line. Pro is an optional one-time purchase.
Is Pro a subscription?
No. Pro is one payment in Google Play: €14.99, or the price Google Play shows in your currency. You pay once and keep it, with updates.
How does KSeF sending work?
You generate a KSeF token in the Ministry of Finance’s Aplikacja Podatnika and paste it into the app. The app sends the invoice to KSeF directly, prints the KSeF number and the verification QR code on the PDF and keeps the UPO and the XML.
Where is my data stored?
Only on your phone. There is no account and no cloud. Invoices leave the phone only when you share a PDF yourself or send an invoice to KSeF.
Which countries does it support?
There are templates for Poland, Germany, Austria, the Netherlands, Sweden, France, the United Kingdom and Ireland, with the right tax ID names, VAT wording and numbering. The invoice language can differ from the app language.
Can I make XRechnung or ZUGFeRD invoices?
Not in this version. In Germany a PDF invoice is still allowed for private customers, for Kleinunternehmer and, depending on turnover, between businesses until the end of 2026 or 2027.
I don’t charge VAT. Does it work for me?
Yes. Turn off VAT in your profile and the app prints the small-business exemption note for your country instead of VAT.
Which phones are supported?
Android 8 or newer.
