When merchants choose a POS system, they’re not simply purchasing a device. They’re investing in a solution that will support daily operations, process every transaction, and play a central role in customer service. That’s why many businesses across Austria, Germany, and Switzerland continue to place significant value on local solution providers who understand the specific needs of their market.
Primasello: The Power of Trusted Local Solutions Built on Global Technology
The best point-of-sale systems aren’t the ones with the most features. They’re the ones that disappear into the background, allowing businesses to serve customers quickly and confidently.
That’s the philosophy behind Primasello, a modern cash register and payment solution designed specifically for small and medium-sized businesses. Combining intuitive software, integrated payment capabilities, cloud services, and compliance with local fiscal regulations, primasello delivers everything merchants need in one seamless platform
Built for businesses, not IT departments
Many traditional cash register systems still require complex installation, external programming tools, or multiple software providers. primasello takes the opposite approach. Its platform is designed to be intuitive enough for independent retailers, cafés, bakeries, restaurants, and service businesses, while remaining compliant with fiscal requirements in Germany (TSE), Austria (RKSV), and Switzerland. Updates, configuration, and cloud services are all handled through a modern Android ecosystem.
Rather than asking businesses to piece together hardware, software, payments, and support from multiple vendors, the solution arrives as a cohesive package: The familiar Primasello brand, software experience, onboarding, and support are combined with the reliability and performance of SUNMI devices such as the D3 Mini and D3 Desktop.
