Overview
BillingEngine is a web-based invoicing program from Hamburg, Germany. It covers quotes, invoices, recurring invoices, multi-level dunning and receipts. Invoices are compliant with ZUGFeRD and XRechnung (EN 16931), and archiving follows the German GoBD rules. Every account also gets its own inbox that reads incoming supplier e-invoices, with no limit, even on the free plan. Other features include stopwatch time tracking that turns timed tasks into invoice items, AI receipt capture, asset depreciation, invoices in six languages and 32 currencies. A tax adviser can get read-only access, and data exports to DATEV, CSV, XLS, XML and PDF. It suits German freelancers, sole traders and teams of up to about ten people who mainly need compliant e-invoicing. Pricing is a flat monthly fee, not per user. The Free plan allows 3 invoices, quotes and receipts per month for one user. Basic costs 7.50 euros a month for 30 of each and two users, and Premium costs 15 euros a month for unlimited documents and five users. Annual billing saves 20 percent. Integration options are limited to a documented REST API, an MCP server and DATEV export. There is no bank connection and no add-on catalogue. That is the main limitation: there is no bank reconciliation or full bookkeeping, and there is only one invoice design and no mobile app. Larger teams or businesses that need DATEVconnect or broader accounting will outgrow it.
