Case Studies
Automation, integrations, accounting systems, and open-source engineering.
Payout evidence belongs with the voucher
A scheduled n8n workflow matches payout PDFs to Lexware card vouchers, handles ambiguity explicitly, and records every attachment result.
Accounting automation that refuses to guess
A fail-closed n8n system reconciles daily SumUp activity before it creates or verifies the matching Lexware revenue documents.
From supplier PDF to an idempotent Lexware invoice
An n8n workflow reads Hamberger supplier PDFs from Google Drive, preserves printed 7% and 19% tax buckets, creates the right Lexware document once, and attaches the source PDF.
