Headless commerce is already well known in online retail. But what is a headless POS?
Headless is an architecture model that is already standard for complex structures. The backend, with more independent and long-lasting functionalities, is decoupled from the frontend. All data such as item data, sales data, inventory data, etc. is available in the backend. The backend serves as data and process management and receives and processes requests from the frontend via so-called "services".
The frontend is the user interface, i.e. what the cashier or employee sees on the display. This can be, for example, an app on a smartphone, a tablet, a handheld device or the app on the stationary cash register. On the one hand, the app requests data from the backend (e.g., stocks, prices, and other data on specific items) and also performs the checkout function.
1. the frontend can be adapted much faster to changing market events. A new design, additional functionalities is all no problem. The frontend and the backend can scale independently. So for individual requirements, all systems no longer have to be turned upside down.
2. any number of frontends can access the backend. The frontend can run platform-independently on any device. The advantage: The devices are usually already available. You don't need extra hardware. This saves costs.
3. performant applications are more important today than ever before. The frontend does not store any data. All required data is supplied from the backend. The frontend can therefore run at very high performance. For example, the checkout process can be completed quickly - avoiding long waiting times for the customer.
4. the frontend can access different data sources. Whether it's the POS backend, ERP, CRM, eCommerce backend, or PIM, the frontend talks to all connected data sources.
The big advantage is that the app can be installed on a smartphone, tablet or other device. Cashiering, access to inventory or sales data, or back-office functions can thus take place from any location.
Headless architectures are also very well suited for integrating microservices. Microservices are, as the name suggests, small. They are also independent and are there to perform a specific task. This makes maintenance and expansion very easy. If there is a better alternative for a microservice, it can be replaced without any problems.
