Invoices that are simply right
Professional invoices in minutes – with the right rules for your business.
Number sequences, mandatory details and statuses are handled automatically – recurring invoices and reminders run almost on their own.
Invoicing
Create a professional invoice as PDF in minutes. Gewerber knows the small-business rule (§19 UStG) and common VAT logic – including reverse charge – and applies it automatically. Templates come in German, English, Russian and Turkish. Recurring invoices, e-mail reminders and payment recording are already included, too.

To your first invoice in three steps
Check your small-business status
In your business profile you decide whether you invoice under §19 UStG. Gewerber derives all tax wording from it.
Add your line items
Client, service, amount – based on a template in your language. Gewerber assigns the invoice number automatically.
Send the PDF & track status
Send the finished PDF, record payments and keep an eye on open amounts all the way to reminders.
What's inside
§19 UStG without guesswork
You state once whether you use the Kleinunternehmer rule. From then on Gewerber creates your invoices without VAT – including the legally required notice. The reverse-charge note for cross-border work is applied correctly too.
Sequential numbers & clean PDFs
Gewerber issues sequential invoice numbers per business and year – GoBD-friendly, gap-free, with a freely chosen prefix. The result is a professional PDF based on your template, in German, English, Russian or Turkish.
Statuses & open amounts always visible
Every invoice moves through clear states: from draft and sent to paid – including partial payments and overdue marking. Your open receivables are visible at a glance.
Recurring & follow-up reminders
For retainer work you create recurring invoices once – Gewerber keeps issuing them automatically. If a payment is late, send email reminders straight from the invoice.
Invoicing
Invoicing is part of Gewerber's open core (MIT) – payment processing is excluded and follows as a separate module.
Frequently asked questions
How does Gewerber implement the Kleinunternehmer rule (§19 UStG)?
You store your status once in the business profile. Invoices then carry no VAT breakdown but the prescribed small-business notice – so you never invoice incorrectly by accident.
How are invoice numbers assigned?
Automatically and sequentially, per business and year. You can adjust prefix and format; issued numbers stay protected, so no gaps or duplicates can occur.
Can I send reminders by email?
Yes. You create a reminder directly from the open invoice and send it by email – dispatch is scheduled and logged.
Which statuses does an invoice have – and where do I see open ones?
From draft via sent and partially paid to paid, overdue or cancelled. The overview always shows which amounts are still open.
Can I invoice the same client regularly?
Yes, that's what recurring invoices are for: create once, pick an interval – Gewerber issues the next invoice automatically when it falls due.
