Services by audience
Public-sector clients require XRechnung, and your own systems do not produce it.
Three packages with a fixed scope and a starting price calculated from the estimated hours. Owner-managed, based in Hanau, Germany.
How to read the prices
Every amount is a starting price ("from"), calculated from the estimated hours. The large figure is the final price including 19% VAT, the net amount is shown below it.
Only the written quote after a short exchange is binding. It is valid for 14 days.

Funding
Your project may be eligible for funding — subject to review by the funding body. Whether a programme is open and fits your project is decided by the funding body alone.
Preparation
None of this has to be finished. It only helps to keep the questions short.
1
The Leitweg-ID of your public-sector client.
2
The program your invoices come from today.
3
The steps that are still done by hand.
Evidence
The services come from the same workshop as our own products. Their pages show what has been built — the products themselves are launching soon.
