How to start with e-invoicing

Your billing system keeps producing the invoices and credit notes it produces today. Aivatar turns them into checked e-invoices in ZUGFeRD or XRechnung format. You approve, you download, and everything stays archived for 10 years.

Setup in three steps

Once, about five minutes. After that everything is ready for every further batch.

Company profile and logo — Address, VAT ID or tax number, IBAN and contact details. Every e-invoice is issued from these, and your logo sits at the top of the PDF. It is required before the first upload.
Look at the example — An ordinary invoice next to the e-invoice it becomes, so you know beforehand what you get. It costs nothing.
Upload your first documents — That completes the setup. You do not have to connect a mailbox.

From document to e-invoice

The routine you have from then on. Nothing is sent without your approval.

Convert documents — Click "Convert documents" and pick or drop your files: PDF, XML, Word, Excel or a photo. Several invoices in one PDF are split automatically. Credit notes, corrected invoices and self-billed credit notes are recognised.
Automatic checking — Every document is read, rebuilt as an e-invoice and recalculated against the totals printed on the original. Official validation follows.
Approve — One click approves every document that passed every check. Documents marked "Check" you open one by one: correct a value and have it checked again, or confirm that the values are right.
Download and send — Download all approved e-invoices as a ZIP and send them to your customers the way you do today.

What it costs

Every size includes every feature plus help getting started by email and, if needed, a short online call. What counts is every invoice or credit note we convert, check and archive for you, up to 10 pages, whatever file format it arrives in. Checking e-invoices you receive costs nothing.

Good to know

Do I have to change my billing system? — No. You carry on exactly as before and only upload the finished documents.
Do I need a mailbox? — No. A mailbox can be connected optionally, if e-invoices sent to you should be collected automatically.
What happens if a document is read wrongly? — Then the recalculated totals do not match the original, and the document is marked "Check" with the exact reason. It is never approved automatically.
When does e-invoicing become mandatory? — Every German company has had to be able to receive e-invoices since 1 January 2025. Issuing them is mandatory from 1 January 2027 above 800,000 EUR of prior-year revenue, and from 1 January 2028 for everyone else. This is not tax advice.
