What It Is

GreenBill is a digital receipt and e-invoicing solution for offline POS systems, positioned much like adding a “digital invoice printer” to an existing checkout setup. It emphasizes that merchants do not need to replace their current POS system: paper receipts can be converted into digital receipts, and customers can generate e-invoices by themselves from the digital receipt, reducing the amount of invoice-information entry required from store staff.

Core Features and Integrations

Based on the information shown on the site, GreenBill covers digital receipts, merchant receipt archiving, smart search, automatic email sending, hospitality/entertainment receipts, ZUGFeRD-format e-invoices, digital signature workflows, real-time customer feedback, tipping, and the ability to display image, video, or link-based ads on digital receipts and customer-facing displays. It can also pass POS data to other applications and be integrated into an existing customer app. For payments, the page explicitly mentions support for digital payment methods such as PayPal and Alipay.

Pricing and Trial

Pricing is relatively clear but incomplete: Basic costs 290 euros/year and includes up to 120,000 receipts per year, with annual billing that can be canceled; Pro costs 490 euros/year. The page also shows an annual/monthly billing toggle and an entry point for hardware information, but the captured content does not provide monthly prices, the full differences between Pro and Basic, or hardware fees. New customers can receive free months, but it is not clear whether there is a standard free trial or a permanently free plan.

Pros and Cons

The main strength is its clear focus: it targets the post-checkout workflow with e-invoicing, receipt archiving, payment extensions, and customer engagement, which has practical value for restaurants, hotels, and ticketing scenarios. It also showcases case studies such as Dorint Hotels, PLENUM, and Kunsthalle München. The limitation is that the website does not disclose common enterprise procurement details such as security and compliance, permission management, deployment model, or API documentation. The exact boundaries of its claim to “work with any POS system” also need to be confirmed with sales.

Who It’s For and Access from China

GreenBill is better suited to offline merchants in Germany and Europe, especially businesses that need ZUGFeRD e-invoicing, digital receipts, hotel signature workflows, or hospitality/entertainment receipts. For Chinese merchants, the value of German e-invoicing compliance and compatibility with the local POS ecosystem is limited; domestic options such as Youzan, Weimob, Keruyun, 2Dfire, and Hualala may be better starting points for comparison. The text does not disclose network accessibility from China or subscription payment availability, so these need to be tested directly.
