Choosing the right POS system for your coffee shop isn't just about processing payments anymore, it's about managing inventory, tracking your best-selling flat whites, handling loyalty programmes, and keeping queues moving during the morning rush. Get it wrong, and you're stuck with clunky software that slows you down when you need speed most.
We've tested and compared three popular options that coffee shop owners are considering in 2026: Toast, SumUp, and Shopify POS. Each has its strengths, but they're suited to very different types of operations. Let's break down which one makes sense for your setup.
Toast POS: The Heavy-Hitter for Food-Forward Coffee Shops
Toast has built a solid reputation in the hospitality world, and for good reason. If your coffee shop serves more than just drinks, think pastries, sandwiches, brunch plates, Toast is designed with you in mind.
What Makes Toast Stand Out
Toast's biggest strength is its offline mode. When your Wi-Fi drops during a Saturday morning rush, Toast keeps running. You can still take orders, process card payments, and keep the queue moving. Everything syncs automatically once you're back online.
The kitchen display system (KDS) is brilliant if you've got a proper food operation. Orders flow straight from the till to the kitchen screen, cutting down on miscommunication and keeping your baristas and kitchen staff coordinated. It's a game-changer if you're doing breakfast and lunch service alongside your coffee menu.
Toast also offers the Toast TakeOut app, which handles online ordering directly without relying on third-party delivery apps. You keep more margin, and customers can order ahead for collection. The built-in loyalty programme (£50/month extra) integrates seamlessly, letting you reward your regulars without faffing about with separate systems.
The Downsides
Toast isn't cheap. The software fees add up quickly, especially once you factor in the loyalty programme, online ordering, and any add-ons. Hardware costs are higher too, you're looking at a proper investment upfront.
It's also quite feature-heavy, which is brilliant if you need those features but can feel like overkill for a simple grab-and-go coffee spot. If you're just slinging espressos and pre-packaged pastries, you might be paying for functionality you'll never use.
Pros:
- Offline mode keeps you running during internet outages
- Kitchen display system for food operations
- Toast TakeOut app for direct online ordering
- Strong loyalty programme integration
- Built specifically for hospitality
Cons:
- Higher pricing than competitors
- Can be overkill for drink-only coffee shops
- Steeper learning curve for staff
- Locked into Toast's payment processing
Best For
Larger coffee shops with steady foot traffic and a proper food menu. If you're doing made-to-order breakfast and lunch alongside your espresso bar, Toast makes sense.
SumUp POS: The Budget-Friendly Option for Independents
SumUp has carved out a niche as the affordable, no-nonsense option for small businesses. It's particularly popular with independent coffee shops that want to keep costs down without sacrificing essential features.
What Makes SumUp Appealing
The pricing is refreshingly straightforward. SumUp doesn't lock you into monthly subscriptions for basic features, you pay a flat card transaction fee (1.69% for chip and PIN) and that's largely it. The hardware is affordable too, with card readers starting around £29 and the SumUp POS Lite system available for under £200.
Setup is dead simple. You can be taking payments within hours, not days. The interface is intuitive enough that new staff can learn it during a single shift, which is brilliant when you've got high turnover or seasonal workers.
SumUp's inventory management handles the basics well, tracking stock levels, setting low-stock alerts, and managing modifiers for your drinks menu. It won't blow your mind, but it does what most small coffee shops actually need.
The Limitations
SumUp is light on hospitality-specific features. There's no proper kitchen display system, the loyalty programme options are basic, and you don't get the depth of reporting that Toast or some other systems offer. If you're planning to scale or add complexity, you might outgrow SumUp fairly quickly.
The offline mode is limited compared to Toast. You can take contactless payments offline, but the functionality is more restricted. If reliable internet is a concern in your location, this matters.
Pros:
- Very affordable, low upfront costs and no hefty monthly fees
- Simple to set up and train staff
- Transparent pricing (no hidden costs)
- Good enough for basic coffee shop operations
- Own your hardware outright
Cons:
- Limited hospitality-specific features
- Basic reporting and analytics
- No proper kitchen display system
- Less robust offline mode
- May outgrow it as you scale
Best For
Independent coffee shops, pop-ups, or cafés just starting out. If you're keeping things simple with drinks and pre-packaged food, SumUp gives you what you need without the bloat.
Shopify POS: The Omnichannel Play
Shopify POS is a bit different from the other two. It's really designed for retailers who also want to sell online, but it's found a home with coffee shops that sell retail products, bags of beans, brewing equipment, merch, or gift boxes.
What Makes Shopify POS Different
The unified inventory is Shopify's superpower. Sell a bag of beans in-store, and your online stock updates automatically. Customer buys a KeepCup from your website? It's deducted from your physical inventory. For coffee shops with a retail element, this integration is seamless in a way that most POS systems struggle to match.
The customer profiles are detailed. Shopify tracks purchase history across online and in-store, letting you see exactly what your regulars buy and when. This makes targeted marketing and personalised service much easier.
If you're already using Shopify for your online shop, adding Shopify POS is a no-brainer, everything lives in one ecosystem. You're not juggling multiple platforms or trying to sync data between systems.
The Trade-Offs
Shopify POS feels more retail-focused than hospitality-focused. It doesn't have the food service features that Toast offers, and you won't find a proper KDS or table management. If you're running a busy café with table service and a full menu, Shopify might feel clunky.
The pricing can get expensive once you add apps and integrations. The basic Shopify plan starts at £25/month, but most coffee shops need the POS Pro add-on (£79/month per location) to unlock features like staff permissions and advanced reporting.
Pros:
- Seamless online and in-store inventory sync
- Perfect if you're already using Shopify online
- Detailed customer profiles across channels
- Strong retail product management
- Easy to add e-commerce functionality
Cons:
- More retail-focused than hospitality-focused
- No kitchen display system or table management
- Costs add up with necessary add-ons
- Overkill if you're not selling products online
- Transaction fees unless you use Shopify Payments
Best For
Coffee shops with a strong retail component, selling bags of beans, equipment, or merch both online and in-store. If omnichannel retail is part of your model, Shopify makes perfect sense.

Other Options Worth Considering
While Toast, SumUp, and Shopify POS are solid choices, they're not your only options. Square POS remains hugely popular with coffee shops for its free software tier and customer-facing displays. It's a middle-ground option that's more feature-rich than SumUp but more affordable than Toast.
Epos Now is another strong contender, especially for UK coffee shops. It offers proper hospitality features, integrates with delivery platforms, and their support is UK-based. The pricing sits somewhere between SumUp and Toast, and you get more hospitality-specific functionality than Shopify. If you want a system built for cafés and restaurants with solid inventory management and reporting, Epos Now is definitely worth exploring: we've seen plenty of independent coffee shops thrive with it.
So Which One Should You Choose?
Here's our take based on different coffee shop scenarios:
Choose Toast if: You're running a proper food operation alongside your coffee. If you're doing brunch, lunch service, or made-to-order food, Toast's kitchen display system and offline reliability make it worth the investment. It's built for hospitality, and it shows.
Choose SumUp if: You're keeping things simple: espresso drinks and pre-packaged pastries: and you want to keep costs down. It's perfect for new coffee shops, pop-ups, or independents who don't need bells and whistles. You'll be up and running quickly without breaking the bank.
Choose Shopify POS if: You're selling retail products (beans, equipment, merch) both in your shop and online, and you need that inventory synced seamlessly. The omnichannel capabilities are unmatched, but only if that's actually part of your business model.
The honest truth? There's no single "best" POS system for all coffee shops. The right choice depends on your specific setup, how much food you serve, whether you're selling products online, and your budget. Take demos of a few systems (including Epos Now if you're UK-based), bring your team into the decision, and pick the one that fits your workflow: not the one with the flashiest marketing.
Your POS system should make your life easier, not add complexity. Choose wisely, and your morning rushes will run a whole lot smoother.
