Your point-of-sale system is doing more than just taking payments. It's tracking your inventory, generating sales reports, managing staff permissions, and potentially syncing with your online store and accounting software. Choosing the wrong one means paying for features you don't use, missing features you need, or discovering mid-growth that you've outgrown it.
The good news is that the POS market for small retail has matured significantly. Several solid options exist across different price points and use cases, and the right choice mostly comes down to your business size, transaction volume, and which integrations actually matter to your operation. This breakdown covers the top contenders honestly – what they cost, what they do well, and where they fall short.
Before comparing specific systems, it helps to know what features genuinely matter for a small retail environment versus what's marketing padding.
The non-negotiables for a retail shop are reliable payment processing (card, contactless, and ideally mobile pay), basic inventory tracking, receipt generation, and sales reporting. If you have more than one staff member, role-based permissions matter too – you want to control who can process refunds or access your end-of-day totals. Everything beyond those basics – loyalty programmes, online store sync, purchase order management, advanced analytics – is genuinely useful at certain scales but not universally necessary.
Hardware costs are a real factor that comparison articles often underplay. Most POS systems charge separately for the hardware (card readers, tablets, receipt printers, barcode scanners, cash drawers) on top of the monthly software fee. A system that looks cheap at $29/month can cost $800–$1,200 upfront in hardware if you're setting up a full counter. Always calculate the total first-year cost, not just the monthly subscription.
Before diving into each option, here's a quick orientation on where each system sits:
Square for Retail is the easiest to get started with, has the most generous free tier, and works well for single-location shops with straightforward inventory needs. Transaction fees are slightly higher than some competitors, which matters at volume.
Shopify POS is the strongest option if you already sell or plan to sell online. The in-person and online inventory sync is genuinely seamless, but the software cost is higher and it pushes you toward Shopify Payments to avoid extra fees.
Lightspeed Retail is the most feature-rich of the three for retail specifically – advanced inventory, purchase orders, supplier management – but it's priced accordingly and is best suited to shops with more complex stock management needs.
Clover offers the most flexible hardware ecosystem and works well across different retail setups, but the pricing model is opaque and varies significantly depending on which reseller or bank you go through.
Zettle by PayPal is a lean, low-cost option that suits very small operations – market stalls, pop-ups, boutiques with simple inventory – where simplicity matters more than advanced features.
Square for Retail is built specifically for retail businesses and sits within Square's broader ecosystem. The free plan covers most basics – unlimited products, basic inventory tracking, sales reports, and one integrated card reader included. You pay per transaction rather than a monthly fee, which makes it genuinely low-risk to start with. The paid retail plan starts at around $60 per month per location and adds features like cost-of-goods tracking, purchase orders, and vendor management.
The hardware is clean and purpose-built. The Square Register (a dual-screen countertop setup) runs around $700. The Square Terminal (a standalone device with built-in receipt printer) is around $300 and works well for smaller counter setups. Third-party accessories like cash drawers and barcode scanners work with the ecosystem too.
Transaction fees run at 2.6% + 10¢ for in-person card payments on the free plan, dropping slightly on paid plans. At lower transaction volumes this is fine. At higher volumes – say, $30,000+ per month – the cumulative cost of those fees starts to add up compared to systems with flat monthly pricing and lower per-transaction rates.
Best for: First-time retail shop owners, single-location boutiques, and businesses that want a low upfront commitment with room to grow. Also a strong choice if you want to eventually add online selling, as Square's e-commerce integration is solid.
Key limitations: Transaction fees are higher than some alternatives at scale. Advanced inventory features like matrix inventory (tracking colour/size variants) require the paid plan. Customer support can be slow on the free tier.
Shopify POS makes the most sense if your retail business is already selling online through Shopify, or if you plan to. The integration between online and in-person inventory is genuinely one of the best in the market – stock levels update in real time across both channels, and your customer data, order history, and product catalogue live in one place. That removes a lot of the manual reconciliation headache that retailers with both a physical and online presence typically deal with.
The pricing structure requires some attention. Shopify POS Lite is included with all Shopify plans, which start at $39/month. Shopify POS Pro – which adds features like staff management, unlimited registers, in-store analytics, and smart inventory – costs an additional $89/month per location on top of your Shopify plan. So a mid-tier Shopify plan plus POS Pro at one location runs around $128–$178/month before hardware costs.
Transaction fees are 2.4–2.9% for in-person payments if you use Shopify Payments. If you use a third-party payment processor instead, Shopify charges an additional 0.5–2% on top of that processor's fees, which adds up fast. For most small retailers, Shopify Payments is the practical choice if you're using Shopify POS.
Best for: Retailers who already sell on Shopify or are building a business with both physical and online channels from the start. It's less compelling for brick-and-mortar-only shops, where you'd be paying for Shopify's e-commerce infrastructure whether you use it or not.
Key limitations: The cost climbs quickly once you add POS Pro and factor in transaction fees. Not the most cost-efficient option for low-volume or online-only adjacent businesses.
Lightspeed is the most retail-focused system in this comparison. It was built from the ground up for retailers with complex inventory needs – think multi-location shops, stores with large product catalogues, businesses that order from multiple suppliers, or retailers who need matrix inventory (managing the same product across multiple variants like size, colour, and material). The inventory management is genuinely more capable than Square or Shopify at that level of complexity.
Pricing reflects that capability. Lightspeed Retail starts at around $89/month on annual billing for a single register, rising to $149/month and beyond for plans that include advanced reporting, loyalty features, and e-commerce. Hardware is purchased separately. The transaction fee structure depends on the plan – lower-tier plans use Lightspeed Payments at around 2.6% + 10¢ in-person, which is comparable to Square.
The trade-off is that Lightspeed is more complex to set up and learn than Square or Shopify POS. The feature depth that makes it powerful for established retailers also creates more configuration work upfront. It's probably not the right first POS for someone opening their first shop.
Best for: Established retail shops with large or complex product catalogues, multiple locations, or active wholesale purchasing from suppliers. Particularly well-suited to specialty retailers – outdoor gear, fashion boutiques, bike shops – where variant and supplier management matters.
Key limitations: Higher monthly cost. Steeper learning curve. Overkill for simple, single-location shops with limited SKUs.
Clover is a hardware-forward POS platform that runs on its own proprietary devices. The hardware lineup is well-designed and covers a range of retail setups – from the compact Clover Go card reader to the full Clover Station Solo (a countertop system with a 14-inch screen, receipt printer, and cash drawer built in). The software is app-based, and many features are available through Clover's app marketplace, which gives it meaningful flexibility.
The catch with Clover is the pricing complexity. Clover's software plans and hardware are often sold through banks and payment processors (including First Data/Fiserv, which owns Clover) rather than directly, and pricing varies significantly depending on where you buy. A Clover Station can cost anywhere from $500 to $1,600 depending on the bundle and provider, and monthly software fees typically run $55–$115/month for retail plans. Processing rates also vary by provider. This makes it harder to give a definitive cost comparison without knowing who you're buying through.
Best for: Retail shops that want purpose-built, durable hardware with a broad ecosystem of add-on apps. Works well for businesses that have a banking relationship with a Clover-affiliated provider and can negotiate terms directly.
Key limitations: Pricing opacity is a real issue. Hardware is tied to the platform – if you switch POS providers later, you can't reuse Clover hardware. Always read the contract terms carefully, as some Clover resellers lock you into long-term processing agreements.
Zettle is the leanest option in this group. It's designed for straightforward payment acceptance and basic inventory tracking rather than full retail management. The card reader costs around $29 (with a first-reader promotion often lower), and the software is free – you pay only a flat transaction fee of 1.75% per in-person card payment. There are no monthly fees, no contracts, and no minimum transaction volume requirements.
For a very small retail operation – a single-operator boutique, a pop-up shop, a market trader with a small product range – Zettle's simplicity and low cost are genuine advantages. The reporting is basic, the inventory management is limited to simple product lists, and there's no advanced multi-location support, but for businesses that don't need those features, paying nothing per month and 1.75% per transaction is a strong deal.
Best for: Solo operators, market stalls, pop-up retailers, and small shops with simple product ranges where low overhead matters more than advanced features.
Key limitations: Limited inventory management. No purchase orders, vendor management, or variant tracking. Not suitable for businesses that need to scale or manage complex stock.
The decision tree is simpler than it might look after reading through the options above.
If you're opening your first shop and want to minimise upfront risk and cost, start with Square for Retail on the free plan. It handles most basic retail needs without a monthly commitment, and you can upgrade when you genuinely outgrow it. If you already have or plan to build an online store, Shopify POS is worth the higher cost specifically because the inventory and customer data sync is seamless. If your shop has a large product catalogue, multiple suppliers, or complex variant tracking needs, Lightspeed is worth the premium. If you're a micro-retailer or pop-up operator and volume and simplicity are everything, Zettle's flat fee structure is hard to beat. And if Clover is being offered through your bank as part of a merchant services package, just make sure to read the contract carefully before signing.
Signing up for a long-term hardware or processing contract without reading the terms. Clover and some other systems tie hardware to specific payment processors and may include early termination fees. A system that seems cheap because the hardware is subsidised can cost significantly more over a multi-year term through locked-in processing rates.
Choosing based on free trial experience alone. POS systems typically look good during trials when you're using sample data. The real test is how they handle your actual product catalogue, your staff, and a busy Saturday afternoon. Ask for a longer trial period, and if possible, speak to other retailers in your sector who use the system.
Underestimating hardware costs. The monthly software fee is rarely the whole story. Factor in the card reader, tablet or screen, receipt printer, cash drawer, and barcode scanner – all of which add up fast. Get a hardware quote before committing.
Picking a system you'll immediately outgrow. If you know you're planning to add a second location, launch an online store, or scale inventory significantly in the next 12 months, choose a system that handles that now rather than migrating later.
Do I need to buy hardware from the POS provider? Not always. Square and Lightspeed work with some third-party hardware. Clover requires its own proprietary devices. Shopify POS works with Shopify-compatible card readers and most generic receipt printers and cash drawers. Check hardware compatibility before purchasing anything separately.
What's the cheapest POS option for a very small shop? Zettle has no monthly fee and a flat 1.75% per transaction. Square's free plan is also competitive for simple retail at 2.6% + 10¢ per in-person transaction. For very low transaction volumes, Zettle is usually cheaper. As volume grows, the gap narrows.
Can I switch POS systems later if I change my mind? Yes, but it comes with real friction – migrating product catalogues, customer data, and transaction history takes time, and some systems make data export harder than others. Choosing a system with solid data export options from the start reduces the pain of switching later.
Do these systems handle VAT or sales tax automatically? Yes. All five systems support tax configuration for both US sales tax and UK/EU VAT. You set the rates and apply them to products, and the system handles the maths at checkout and in reports. Always verify your tax settings are correctly configured before you go live.
For most small retail shops in 2026, Square for Retail is the safest starting point – low upfront cost, solid feature set on the free tier, and a clear upgrade path as your business grows. Shopify POS earns its higher price specifically if you're running a multi-channel retail business.
Lightspeed is the right choice when your inventory complexity outgrows what Square can handle. Zettle is the right call when you need to keep overheads as low as possible. And Clover is a reasonable option if you go in with your eyes open about the contract terms.
The best POS system is the one that matches your actual volume, your actual complexity, and your actual budget today – with enough room to grow without forcing a painful migration in 12 months.
