Write invoices, simply & quickly.

For German companies, complying with GoBD guidelines is not optional but mandatory. cashwerk was built from the ground up for the German market and meets all requirements for proper digital bookkeeping: immutable invoice numbers from configurable number ranges, complete archiving in PDF/A format, and full audit trails that make every change traceable. Unlike international tools where GoBD compliance is bolted on afterward, it is a core part of the architecture at cashwerk.

A standout feature is native support for XRechnung and ZUGFeRD. Since November 2020, public-sector clients in Germany must accept electronic invoices in XRechnung format—and e-invoicing in B2B is increasingly standard from 2025 onward. cashwerk generates both formats directly from the invoice screen, without extra software or third-party integration. That saves cost and ensures your invoices meet current legal requirements.

The workflow starts where sales leaves off: from a quotation in the sales pipeline, you create an invoice with one click. All line items, customer data, tax rates, and discounts are taken over automatically. Time tracking connects seamlessly—recorded project hours can be used directly as invoice lines. This end-to-end chain from deal to quotation to invoice eliminates duplicate data entry and keeps errors to a minimum.

Payment management gives you transparency over all open items. You record incoming payments, track the status of each invoice, and always see your current liquidity. Automatic PDF generation stores invoices and cancellations in the integrated Drive so all business documents are archived centrally and stored in a GDPR-compliant way. For sending, use the built-in email function—directly from the invoice view.

For seamless collaboration with your tax advisor, cashwerk offers DATEV export of your invoice data. With one click you generate DATEV-compatible files that your tax office can process directly. Through the full REST API and native n8n nodes, invoicing processes can be automated: pre-built workflow templates like 'Won Deal → Generate Invoice' or daily invoice summaries by email save valuable time. Thanks to smooth integration with accounting tools like sevDesk or Lexware, your financial data flows into preliminary bookkeeping without media breaks.
