BillingEngine is built around e-invoicing from the start. Every invoice is created as an e-invoice (ZUGFeRD and XRechnung, EN 16931), and every plan, including the free one, includes your own inbox for incoming e-invoices without a volume limit. Your tax advisor gets read-only access and can collect the DATEV data set themselves. Beyond the app, BillingEngine offers free tools that need no account (e-invoice validator, viewer, generator and Leitweg-ID checker), a documented REST API and an MCP server for AI assistants. Invoices can be written in six languages and 32 currencies, and all documents are archived in a GoBD-compliant way.
It is a focused, affordable tool for people who mainly need correct invoices. You get compliant e-invoices and an inbox for incoming ones on a permanently free plan, and the paid plans start at EUR 7.50 per month. There is no lock-in: all data can be exported at any time as DATEV, CSV, XLS, XML or PDF. If you want the full range of a large accounting suite, a bigger competitor may fit better. If you want simple invoicing that is ready for the e-invoicing mandate, BillingEngine is a good choice.
Freelancers, sole traders and small businesses in Germany, including small-business owners (Kleinunternehmer) and tradespeople, who write a moderate number of invoices and want them to be compliant without learning about XML formats. A second group is tax advisors, who work with their clients' data, and developers who connect invoicing to their own tools through the API.
BillingEngine was founded to offer small businesses a simple invoicing solution, something its founders could not find on the German market at the time. It launched in 2014 and has been developed continuously with its users and a small team. Since e-invoicing became mandatory for receiving invoices in Germany in 2025, e-invoices have moved to the center of the product. Today more than 2,500 active users rely on it. BillingEngine is developed by DesignBits in Hamburg.
