It’s a matter of life and death for an omnichannel business to operate flexibly, regardless of where the location is. Solution providers have recognized this demand and innovated their software to be a native app that can be accessed anywhere. The trendsetter for this transition is POS (point-of-sale) systems. Today, let us introduce you to the seven best POS apps compatible with multiple mobile devices, tailored explicitly for UK retailers.
The Omnichannel Retail Landscape in the UK
Before jumping straight to the list, we should understand why POS apps are needed in the UK.
In 2022, the UK recorded 85.01 million active mobile devices. This number may lead to the assumption that more people will use their phones for online shopping. However, a survey by Retail Economics UK revealed that consumers still prefer the traditional approach, with 61% of surveyors showing love for in-store shopping. Compared to 39% of online shopping advocates, the gap indicates a strong demand for a seamless omnichannel experience, which applies to both buyers and sellers.
In the past, if POS software had functioned smoothly in brick-and-mortar locations, it would have fulfilled its purpose. However, as we just implied above, a system that exists only in one place has become outdated. Retailers want to manage their store operations from anywhere. A rigid POS system restricts them from remote control. As a result, business owners have shifted to using cloud POS apps.
A flexible POS system simplifies the management process and supports creating a satisfying shopping journey. Since sales reps can get in touch with potential customers immediately without waiting in a long queue, they can increase the chance of a successful deal.

The usual POS software will inevitably be upgraded to a more portable alternative that can be installed on mobiles and tablets. We list below the most popular POS apps in the UK that can support your omnichannel operations.

Square
With its robust omnichannel software and POS hardware ecosystem, Square is a go-to choice for thousands of UK businesses. Unlike ConnectPOS, Square’s POS app does not support Windows users, but you can download the system from the App Store and Google Play.
A notable difference between Square and other providers is their pricing model. You can access every fundamental POS feature for free, though Square charges a processing fee per transaction, which means you must use the Square payment gateway.
Despite the transaction-based pricing, Square is widely used thanks to practical features such as Click-and-Collect and contactless payments.
Lightspeed
Lightspeed, along with Square, can be the most famous POS app for UK companies. With nearly 20 years of experience serving big and small businesses, Lightspeed has transformed into a huge omnichannel system that can support the retail, restaurant, and golf industries.
You can easily download the Lightspeed app for iOS and Android from the marketplace. With a refined interface, users experience a seamless shopping journey from anywhere in the store. With a starting price of $69/month, you can receive great support from:
- Multi-outlet addition and management
- No Internet selling
- Stock transfers
- Hierarchy permission
- Performance reports
Epos Now
Popular among SMEs, Epos Now is a strong option for UK retailers looking for a straightforward POS app. Available on iOS and Android, Epos Now operates in 74 countries and covers the essential features retailers need:
- Real-time synchronization
- Order history
- Stocktake and inventory management
- Sales analysis
- Buy online, pick up in-store

Unlike most providers, Epos Now offers a one-time payment option at $139, which includes POS software, hardware such as a receipt printer and cash drawer, and installation. Additional personalisation and customer support are available at extra cost.
Touch Bistro
Touch Bistro is a POS app designed specifically for restaurants and cafes, where every workflow moves quickly and customers prefer to order and pay at the table. Serving around 29,000 restaurants worldwide, Touch Bistro delivers a consistent experience across all devices.
Starting at $69/month, the platform includes:
- Customer-facing display
- Table management
- Reservations
- Online ordering
- Gift cards and customer loyalty
- Front-of-house and back-of-house communication
Zettle
Zettle is widely known as a payment gateway but also offers a full omnichannel POS solution. With features including inventory management, a customizable checkout process, and sales reporting, Zettle provides a complete in-store experience. The brand also offers its own POS hardware, including a card terminal.
The POS app is free to download from the App Store and Google Play, though Zettle must be used as the payment gateway. This makes it a practical choice for UK retailers, as Zettle is one of the most widely used mobile card readers and payment processors in the country.
SumUp
SumUp offers both omnichannel software and in-store hardware, making it a practical option for service businesses such as barbers, cafes, and restaurants that are building out their multi-touchpoint setup. The app is available for iOS and Android and covers menu management, tips, product suggestions, and reporting.
Pricing (UK):
- Pay-as-you-go: £0/month — 1.69% transaction fee per card payment
- Payments Plus: £19/month — reduced transaction fee of 0.99% for domestic cards
- POS Plus: £39/month (excl. VAT) — advanced hospitality and retail functionality
Transaction fees apply across all plans. POS Plus is suited for businesses needing more advanced stock and floor management tools.
To sum up,
UK retailers have various POS app options, which may get you lost in the way. With this article, we hope you can find a suitable choice for your omnichannel business. Keep in mind some important factors when choosing your dream app.
Each system in this list handles day-to-day retail operations well at a certain scale. Most will serve you reliably when you’re running a single location with a straightforward product catalogue.
The point where many stores outgrow a standard setup tends to follow recognisable patterns:
- Opening a second or third location and needing centralised stock visibility
- Selling both in-store and online at the same time
- Requiring real-time inventory sync across multiple warehouses or fulfilment points
- Needing to assign role-based permissions as the team grows
When any of those milestones hit, the gap between a general-purpose tool and a system built for multi-channel retail becomes more visible – and that’s the right moment to re-evaluate your stack. Chat with us to see how ConnectPOS fits into your next stage of growth.
