What slows you down today and how Jupiter ERP helps

Today: It is unclear how the small business rule must appear on the invoice.
With Jupiter ERP: Choose §19 UStG as your tax type in the first steps. New line items start at 0% VAT. Invoices and credit notes without VAT include the § 19 note. You can turn the note off and place the sentence in a text template.
Today: Software costs money before the first customer has paid.

Guides
Write your first invoice, step by step
The first invoice needs company details, a customer contact, and a number range. This page lists the statutory minimum, the steps in Jupiter ERP, Free and trial limits, and how ZUGFeRD sits in the PDF. It is orientation, not advice on your case.
Learn moreRequired invoice details (§14 UStG)
§ 14 (4) of the German VAT Act lists the details of a regular invoice. Small businesses under § 19 follow the shorter list in § 34a of the VAT Implementing Regulation. This page compares both lists, shows a fictional example, and explains what Jupiter ERP fills from master data. It is orientation, not advice on your case.
Learn moreE-invoicing rules for founders
Since 2025 an e-invoice is a structured file, not a plain PDF. Receiving and issuing follow different deadlines. Small businesses have special issuing rules under § 34a UStDV. This page follows § 14, § 27 (38) UStG, and the finance ministry FAQ. It is orientation, not advice on your case.
Learn moreSmall-business scheme (§19 UStG) in bookkeeping
Under Germany’s small-business VAT scheme (Kleinunternehmer, §19 UStG) you generally charge no VAT and may not deduct input VAT. Expenses and reports are treated gross. Jupiter ERP applies the taxation type to invoices, EÜR views, and depreciation once you set it in accounting settings.
