Three questions, three clear answers

Is this for me?
Yes, if you invoice businesses and do not want large accounting software for it: trades, agencies, consulting, freelancers.
What does it cost?
€0 up to 30 invoices a month, no payment details. App Plus costs €7 a month and keeps your invoices in your account.
Will my invoice be accepted?
Every invoice is checked before it is issued with the KoSIT validator, the official checking program for e-invoices in Germany.

Which deadline applies to you?

For most small businesses it is 1 January 2028. You must already be able to receive e-invoices today.

Two tools that cost nothing

Check a received invoice

You see the e-invoice as a perfectly normal invoice, learn whether it is valid and can save it as a PDF.

Drag the invoice here or choose itXML or PDF, at most 5 MB. The file is processed in memory only and never stored.

Create one invoice

Only an invoice now and then? Fill in the form, we calculate, check and create the file. No account, nothing is stored.

Why not my accounting software?

Honestly: if your accounting software already writes e-invoices and you are happy with it, stay with it. Fakturnaut is for everyone else.

Fakturnaut fits if you …

write invoices in Word or Excel today
leave the bookkeeping to your tax adviser and only want to write invoices
write few invoices a month and do not want to pay for it
want to read and check the e-invoices you receive

Stay with your software if you …

already do bookkeeping, banking and tax in one place
already issue valid XRechnung or ZUGFeRD invoices there

Not sure your invoices are valid? Check one of them here for free.

Frequently asked questions

I am a small business under § 19 UStG. Do I need this?

You do not have to issue e-invoices, but you must receive them. You can read and check the e-invoices you receive with us for free.

What is the difference between ZUGFeRD and XRechnung?

Both follow the European standard EN 16931. ZUGFeRD is a PDF that you and your customer read as usual, with the invoice data inside. XRechnung contains the data only. Fakturnaut creates both.

What happens after 30 invoices a month?

You switch to App Plus in the app for €7 a month. App Plus has no monthly limit.

What happens to my data when I cancel?

You can download the complete export at any time. Before we delete anything, we tell you by e-mail.
