RechnungAPP

Invoicing shaped for tradespeople, not for accountants

Case study. This system is private — its architecture is described here, but it is not linked and no real data or media from it appears.

An invoicing tool aimed at Handwerker — the people who need a correct, sendable invoice from a van, not a general ledger.

Scope is deliberately three surfaces: a landing page, a login, and a dashboard. The core is PDF generation — the document is the product, so it is rendered properly rather than printed from HTML and hoped for.

Dormant. No live application URL is published from here.
