FinanzFlux is a German-language accounting platform built specifically for e-commerce self-employed and small business owners. It covers the full accounting workflow: income-surplus accounting (EÜR), VAT pre-returns (UStVA), transaction management, and document handling with automatic receipt recognition. Unlike generic accounting tools, FinanzFlux is designed around the real workflows of online sellers — connecting transactions, matching receipts automatically, and generating the reports that German tax law requires. No accounting knowledge needed.
