The main answers before
you take a closer look.

Yes. The shared editor supports text, images, tables and placeholders. Organize templates by document type, set a default template and customize your line-item columns.
Yes. There are line-item and document discounts, optional items, and partial and cumulative invoices. Amounts already invoiced and payments actually received are shown separately. Manage payments, due dates and reminders in outstanding invoices.
Email features use IMAP for receiving and SMTP for sending. Enter the connection details in settings.
AI processing is designed for a local Ollama server. Speech is processed using Android’s local speech recognition. Supported hardware and an offline speech model are required; requests can also be typed.
Enter a net purchase price and a percentage markup in the catalog. A €100 purchase price with a 25% markup gives a €125 net selling price. Alternatively, set your selling price directly. Existing invoice line items retain their prices.
Business address, tax details, bank details, payment terms and numbering formats for each document type. Combine prefixes, dates and sequential numbers. Email templates also use the shared template editor.
Document finalization, archived original files, signed change logs, integrity checks and audit exports provide technical foundations. Full compliance with German GoBD requirements also depends on actual business procedures, retention and backups; no such certification is claimed here.
Yes. The live demo opens the actual application with fictional Werkraum sample data. Work freely with customers, projects and documents. The shared demo resets daily at 04:00 German time. Please do not enter real data.
