The EUR 800,000 test, applied to your entity Applies the prior-calendar-year turnover test in Sec. 14 UStG to decide whether your first mandatory issuing date is 2027-01-01 or 2028-01-01, and names the reason.
Days of buffer between go-live and the mandate Subtracts the date your XRechnung or ZUGFeRD issuing setup goes live from your binding date, so a late project shows as a negative number instead of a feeling.
Days overdue on the receiving duty Counts the days since 2025-01-01, when every domestic German business had to be able to receive a structured e-invoice, whatever its turnover.
Invoices actually in scope per year Removes the share of small invoices at or under EUR 250 from your annual German B2B volume, so the migration is sized on the invoices the mandate really touches.
What a year of rejected PDFs costs Multiplies in-scope invoices by your rework minutes and loaded hourly cost to price a year of correcting and re-issuing invoices a buyer refuses.
The 8-year archive year Applies the Sec. 147 AO retention period, shortened from ten to eight years on 2025-01-01, counting from the end of the year the invoice arose.

2027-01-01 or 2028-01-01, the go-live buffer you have left, and the 8-year archive year
A German tax adviser's statutory time fee is EUR 35 to EUR 107.50 per half hour (Sec. 13 StBVV), so EUR 70 to EUR 215 for one scoping hour on these dates.
It applies the German Sec. 14 UStG e-invoicing rules to one entity and returns seven things: your first mandatory issuing date, days left to it, the buffer between your go-live date and that date, days since the 2025-01-01 receiving duty began, invoices in scope per year, the cost of a year of rejected-invoice rework, and the archive year.
Who is it for?
Finance-ops, AP and AR leads at non-German groups that sell into Germany through a German GmbH, UG, AG or registered branch, and who read their rules in English. It is also used by shared-service centres that run several German entities and need each one's date separately rather than one blanket answer.
Why will a free chatbot or a timeline blog not do?
They answer for Germany, not for your entity. They quote 2025, 2027 or 2028 as if one date applied to everyone, and they skip the three switches that decide it: the EUR 800,000 prior-calendar-year turnover test, the small-business exemption from issuing, and the case where you have no German establishment at all.
What is free and what does the paid version add?
Every calculation is free, in the popup and on the web page, with no key and no limit. The paid licence adds two things on a different axis: exporting the worked schedule as a .csv row you keep per entity, and a browser reminder set on your go-live date and your binding date.
What would this cost me otherwise?
A German tax adviser bills a statutory time fee of EUR 35 to EUR 107.50 per half hour under Sec. 13 StBVV, so EUR 70 to EUR 215 for a single scoping hour on these dates, per entity, repeated every time your turnover or your project plan moves. The licence is 60 US dollars once.
