Foreword
Retail is undergoing a profound transformation. Today, customers expect a shopping experience that seamlessly integrates brick-and-mortar and digital offerings. For retailers, this means meeting various demands simultaneously: compliant cash register processes, reliable payment processing, cross-channel inventory management, flexible hardware, and a back office that centrally provides and efficiently utilizes data. Smartstore addresses this environment with a POS system that functions not only as a cash register but as part of a fully connected commerce platform.
Smartstore POS consistently, technically robustly, and compliantly represents the entire sales process. The solution merges traditional in-store procedures with modern e-commerce structures, creating unified management of all relevant business areas. Whether a single location, a chain of stores, or mobile sales concepts: Smartstore consolidates data, inventories, and transactions within a centralized infrastructure. This reduces sources of errors, simplifies work processes, and enhances decision-making foundations.
Of particular note is the system's technical openness. Smartstore is open source and supports cash register systems from the internationally operating manufacturer Sunmi, known for robust and high-performance POS hardware. Simultaneously, the solution remains flexible enough to incorporate devices from other manufacturers if needed. This also applies to payment integration: With over 100 connected payment providers worldwide, a wide range of options for different markets and requirements is available.
Another crucial aspect is tax compliance. In Germany, Smartstore partners with Fiskaly, a leading provider of TSE management. This ensures the system meets the requirements of the KassenSichV and ensures the proper, audit-proof recording of all transactions. As a result, retailers gain the confidence that Smartstore operates reliably even in sensitive areas like fiscalization and receipt archiving.
Smartstore POS is therefore much more than just another cash register software. It is a globally deployable, comprehensive ecosystem that represents the entire sales process across channels. The nine points presented below detail how Smartstore systematically addresses these requirements and the specific benefits for retail.
1. Core Promise: One POS for All Sales – In-Store and Online

Smartstore provides the POS system as a central solution for all sales processes – both in brick-and-mortar stores and digital channels like online shops, marketplaces, or social commerce environments. The platform aims to support retailers from a single software solution without parallel systems or isolated data structures.
The result is a unified system for in-store sales, online shop, and back office. It is suitable for companies starting with one location as well as for retailers planning growth, additional stores, or further sales channels. Smartstore scales with business requirements while remaining technologically flexible.
The central message: Smartstore unites all sales channels in one solution, creating the foundation for more efficient processes and sustainable growth. Companies can organize their processes more tightly, seamlessly integrate online commerce, and structure their back office much more efficiently. This facilitates the use of existing resources and supports long-term expansion.
