Billomat

Billomat is a purpose-built invoicing and accounting tool for the German market, and for agencies and freelancers operating in Germany, its combination of GoBD compliance and DATEV integration addresses two of the most important requirements in German financial software. While international tools like Wave or FreshBooks may offer broader feature sets, they typically lack the compliance certifications and tax advisor workflows that German agencies need.

The DATEV export capability is a major time-saver for agencies working with German tax advisors. Instead of manually preparing and sending bookkeeping data, Billomat generates export files that tax advisors can import directly into DATEV, eliminating a tedious monthly process. Automatic bank reconciliation matches incoming payments to invoices, reducing the manual effort of tracking who has paid and who hasn't. Recurring invoices handle retainer clients automatically, and payment reminders chase overdue invoices without agency staff needing to send awkward emails.

Compared to sevDesk or lexoffice, Billomat focuses more narrowly on invoicing and bookkeeping rather than trying to be a full accounting suite. This makes it simpler to use but means agencies needing expense tracking, payroll, or financial reporting will need additional tools. For agencies whose primary finance pain point is invoice creation, GoBD-compliant archiving, and DATEV sync, Billomat delivers a focused solution that does those things well.
