The InStore POS application: Built for the modern store associate
  • One responsive POS experience across devices: From fixed workstations to tablets and handhelds, without separate applications or codebases. 
  • Productized but not prescriptive: Start with core POS capabilities out of the box, while tailoring the store associate experience to your brand and way of selling. 
  • Differentiate where it matters: Extend or replace specific experiences, such as the selling cart, while keeping core capabilities like Payments and everyday store operations. 
  • Get to value faster: Start with a working application, validate experiences with store colleagues earlier and evolve without rebuilding your POS from scratch.

Flexible POS technology for today’s multitasking store associates 

The traditional picture of retail checkout — a customer standing at a fixed counter while an associate operates a workstation — is only one part of today’s store experience. 

Associates are increasingly moving around the sales floor, using data and digital tools to support customers wherever the interaction happens. They might check inventory at another location, look up a loyalty profile during a conversation, process a return for an online purchase, help a customer place an order for an item that isn’t available in-store, or complete a transaction on a tablet or handheld device.

In other words, the associate is no longer necessarily tied to a register. The technology in their hands shouldn’t be either.

That shift creates a challenge for POS systems. Traditional packaged POS applications can be highly capable, but they have often been designed around fixed workstations and predefined workflows. At the other end of the spectrum, building a highly customized POS experience from the ground up can give retailers enormous flexibility, but it also requires significant development, testing, maintenance and operational effort.

The new productized InStore POS application is hosted and maintained by commercetools, with core InStore capabilities available out of the box. 

Retailers don’t have to start by assembling and maintaining every part of a POS application themselves. It’s designed to sit between those two extremes: A ready-to-use POS application with core capabilities available out of the box, while giving retailers the flexibility to adapt the associate experience to the way they actually sell.

One POS experience, wherever the associate works

The InStore POS application is browser-based and responsive, so the same interface can adapt from a desktop workstation to a tablet or handheld device from a single codebase. There’s no separate mobile application to build, download, install and maintain.

This gives retailers more flexibility in how and where associates work:

  • Fixed workstation: Complete transactions at a traditional register.
  • Handheld: Help customers on the sales floor with use cases such as queue busting and flexible fulfillment.
  • Tablet: Browse products together with customers and support consultative selling.

The device becomes a choice based on the job, rather than a constraint of the POS.

The experience can also be tailored to the retailer. With API-first theming, retailers can adapt elements such as colors, typography, component styling and responsive layouts to reflect their brand and how their associates work – workstation by workstation.

Under the hood, the application runs on modern browsers and has been tested with the Blink and WebKit rendering engines used by popular desktop and mobile browsers. As a Progressive Web App, it combines the accessibility of a browser-based application with an experience designed to withstand internet connection outages, regardless of the device.

This also simplifies the technology landscape for store operations and IT teams. As retailers create different types of stores, from kiosks to experiential retail, they can use the same application across different store formats and devices without introducing separate applications or complex configurations.

The result is less dependence on a particular operating system, workstation or device, and more freedom to choose the hardware that fits the store’s operating model.

A responsive POS application that adapts to how you sell 

Consider the out-of-the-box InStore POS Cart. Designed for fast, everyday selling, associates can quickly scan merchandise-present items into a take-with cart, then hand the transaction over to the core Payments capabilities to take the tender and issue the receipt.

The cart can also combine merchandise-present items with order items that may be out of stock, giving associates flexibility to serve customers in a single transaction. And it’s not just about selling. The InStore POS application also supports the everyday store operations that keep things running:

  • Find past transactions when customers need help with a previous purchase.
  • Reprint receipts when a printer jams or a customer needs a gift receipt.
  • Manage cash movements securely between repositories.

These aren’t necessarily the “sexy” parts of the experience retailers want to differentiate, but they need to work nonetheless. 

When your selling experience needs to be different

Now consider a more consultative selling approach. An associate and customer might browse products together, select colors and materials, configure options and decide whether the finished item should be delivered or collected.

In this case, a rapid take-with cart may not be the right experience — and that’s okay. With the InStore POS application, retailers can extend or replace the out-of-the-box cart with a consultative selling experience tailored to their sales process, while continuing to use the same POS application.

The retailer can keep the capabilities that don’t need to change, such as Payments and the everyday operational workflows, and customize the part of the experience that matters most to its customers and associates.

Faster to start, easier to evolve

For retailers, the value of a productized InStore POS application is that the starting point is already a working application, while the architecture leaves room to differentiate where it matters. That can help teams move faster from an idea to a proof of concept, get store-colleague feedback earlier, and learn from real usage before committing to a large-scale custom build.

Instead, retailers can start with the core capabilities they need, adapt the associate experience around their specific operating model, and continue evolving it over time.

The InStore POS application provides a productized foundation for everyday store operations, while its composable approach gives retailers room to create the experiences that make their stores different.
