An invoicing tool that knows the whole thread
In cashwerk the invoice is not an end point but a link in the chain: deal, quote, project, tracked time, invoice, payment. Every document knows where its numbers come from.
Most invoicing tools do exactly one thing: a PDF. cashwerk attaches the invoice to the thread. Line items come from the quote or from tracked hours – with a guard against double billing –, the customer from the CRM, the costing from the product & service catalogue. Change something on the project later and you see the deviation in the cockpit instead of in a spreadsheet next to it.
GoBD compliance is built into the architecture: configurable number sequences without gaps, booked documents are immutable, corrections run as cancellation or credit note linked to the original, and invoices are produced as PDF/A-3. Tax rates, the small-business rule and tax-exempt cases are on file; reverse charge under § 13b is set up once as a rule. So the invoice is not just pretty but right.
Invoices, cancellations and payments are unlimited on every plan, including the free plan for one user. Reports and exports come with Starter, and so does the DATEV posting batch. E-invoicing and dunning belong to the Business plan, as do the Lexware and sevDesk connections.
