Point of Sale Systems Compared for Small Shops
Your point of sale system does far more than take payments. It holds your product list, tracks stock, records every sale and often decides how easily you can sell online too. This guide compares the main point of sale systems small shops look at, shows you which questions really separate them, and gives you a scoring template so you can choose with confidence.
Key takeaways
- Choose a point of sale system based on how you sell: in store only, in store plus online, or with table service or appointments.
- Square, Shopify POS, Clover, Lightspeed and SumUp each take a different approach to hardware, payments and software plans.
- Compare the total cost: card processing, software subscriptions, hardware and add-ons, not just the headline rate.
- Check whether you are tied to one payment processor and how easily you can export your data if you leave.
- Run a short trial with real products and staff before you switch on a busy day.
Mid-March is a natural time to review your till. Spring trade is picking up, you may be hiring seasonal staff, and if your current system has frustrated you all winter, switching before the busy months is far easier than switching during them. This guide is not a ranking. There is no single best system, only the one that fits how your shop works.
Features, plans and pricing change often, so treat everything here as a starting point and check each provider's current features, pricing and privacy policy before you sign up.
What a point of sale system does for a small shop
A modern point of sale (POS) system usually combines several jobs in one place:
- Taking payments: card, contactless, mobile wallets and sometimes cash drawer management.
- Product catalog: names, prices, variants such as size and color, and barcodes.
- Inventory: stock levels, low stock alerts and purchase orders.
- Reporting: daily sales, best sellers, slow movers and staff performance.
- Customers: receipts by email, customer profiles and sometimes loyalty programs.
- Staff: logins, permissions and sometimes time clocks.
- Online selling: a connected web shop or integration with one, sharing the same stock.
Most systems cover the basics. The real differences show up in inventory depth, online selling, hardware choice and how you pay for the whole package.
The main systems compared
Here is a plain-language overview of five systems small shops often consider. Each has many plans and options, and availability differs between the US, UK and Europe, so confirm what is offered in your country.
Square
Square is known for an easy start: you can begin with a phone or tablet and a card reader, then add more hardware later. It offers point of sale apps for different business types, such as retail, restaurants and appointments, and it can connect to an online store. It suits shops that want to get going quickly with little setup. Square also offers QR code ordering features for food businesses.
Shopify POS
Shopify POS is built around the Shopify ecommerce platform. Its strength is selling in person and online from one product list and one stock count. If your web shop already runs on Shopify, or online sales are a big part of your plans, it is a natural option to look at.
Clover
Clover focuses on all-in-one countertop and handheld hardware, with an app market for extra features. It is often sold through banks and payment providers, so the plan, pricing and support you get can depend on who sells it to you. Read the contract carefully, including the term and any equipment terms.
Lightspeed
Lightspeed offers retail and hospitality versions aimed at businesses with larger or more complex catalogs. Retail shops with many variants, multiple suppliers or detailed purchasing needs often look at it for its inventory tools.
SumUp
SumUp is popular with very small businesses, market traders and mobile sellers in the UK and Europe, starting from simple card readers. It also offers point of sale options for shops and cafes. It suits businesses that want a light, low-commitment setup.
Pro tip
If you run a cafe or restaurant, also look at systems built for hospitality. Toast is designed for restaurants, and Sunday focuses on QR code ordering and paying at the table. Retail-first systems can work for food, but table service features differ a lot.
Costs to compare before you choose
The headline card rate is only one part of what you pay. To compare fairly, list every cost for each system:
- Card processing fees: often a percentage plus sometimes a fixed amount per transaction. Rates may differ for in-person, online and keyed-in payments.
- Software subscription: many systems have a free or basic tier and paid plans with more features. Check what is included at each level.
- Hardware: card readers, terminals, tablet stands, receipt printers, cash drawers, scanners and label printers.
- Add-ons: loyalty, advanced inventory, staff scheduling, extra locations or extra registers can each cost more.
- Contract terms: monthly vs fixed term, early cancellation fees and equipment leases.
Common mistake
Signing a multi-year equipment lease or processing contract without reading the cancellation terms. Leasing hardware can cost much more over time than buying it outright, and leaving early can be expensive. Ask for every fee in writing, and check whether you can use your own processor.
Also check payment processor lock-in. Some systems only work with their own payment processing, while others let you choose. Being locked in is not always bad, since it can make setup simpler, but it means you cannot shop around for processing rates without switching your whole system.
How to choose: a step-by-step process
- Describe how you sell. In store only, in store and online, at markets and events, or with table service. Note your number of products and variants.
- List must-have features. For example: variant inventory, purchase orders, online store sync, staff permissions, gift cards or loyalty.
- Shortlist two or three systems. Drop any that do not support your country, your business type or a must-have feature.
- Estimate your monthly cost. Use your typical monthly card sales, the provider's published rates for your country, the plan you need and the hardware.
- Check data and exit. Can you export products, customers and sales history? What does it take to leave?
- Trial with real use. Use a free trial or demo. Add 20 real products, ring up test sales, run an end-of-day report and ask a team member to try it.
- Plan the switch. Pick a quiet day, import products, test hardware and keep your old system available for a few days if possible.
A POS scoring template
Copy this into a spreadsheet. Score each must-have from 1 to 5 after your trial, and add your estimated costs. The figures below are made-up examples for illustration only.
| System | Inventory score (1 to 5) | Online sync score (1 to 5) | Ease for staff (1 to 5) | Est. monthly cost (example) | Hardware upfront (example) | Data export? |
|---|---|---|---|---|---|---|
| Option A | 3 | 5 | 4 | $210 | $600 | Yes, CSV |
| Option B | 5 | 3 | 3 | $260 | $900 | Yes, CSV |
| Option C | 2 | 2 | 5 | $140 | $150 | Partial |
Weight the scores by what matters most to you. A shop that sells mostly online will care about sync; a shop with hundreds of variants will care about inventory.
Hypothetical example
Imagine Tom and Aisha, who run a small homeware shop with a growing web store. Their current till does not share stock with their website, so they keep overselling items online. They shortlist two systems with strong online sync, trial both for a week with 30 real products, and find one handles their candle variants and supplier reorders far better. They switch on a quiet Monday in early April, after the spring display change, and keep their old reports exported as a backup.
Policies, receipts and compliance basics
Your POS is also where customer-facing policies show up, so set them up on purpose.
- Returns and refunds: make sure your system can process refunds and exchanges cleanly. In the UK and EU, consumers usually have 14 days to cancel most online purchases. In the US there is no general federal right to return, so your store policy applies, and some states require the policy to be posted. Print or link your policy on receipts.
- Sales tax and VAT: set up tax rates correctly for your location and products, and check them with your accountant.
- Customer data: if you collect emails at checkout, be clear about what you will send. In the UK and EU, PECR and GDPR consent rules apply to marketing emails; in the US, CAN-SPAM requires a clear unsubscribe option and a valid physical postal address in commercial emails.
- Staff access: give each person their own login and limit refunds and discounts to trusted roles.
This is general information, not legal or tax advice. Rules vary by country and state, so check official sources or ask a qualified professional about your setup.
Your POS selection checklist
- Write down how you sell and how many products and variants you have
- List your must-have features
- Shortlist two or three systems available in your country
- Collect current processing rates, plan prices and hardware costs
- Read contract terms, lease terms and cancellation fees
- Confirm you can export products, customers and sales history
- Trial with real products, real staff and an end-of-day report
- Set up returns policy, tax rates and staff permissions
- Switch on a quiet day and keep a backup of old data
Frequently asked questions
Can I switch POS systems without losing my data?
Usually you can export products and customers as spreadsheet files and import them into the new system. Sales history is harder to move, so export reports from your old system and keep them for your records before you cancel.
Do I need a POS system if I only sell at markets?
A simple card reader with a phone app may be enough at first. If you want stock tracking, sales reports or an online shop later, choose a provider that lets you grow into a fuller system.
Is it better to buy or lease POS hardware?
Buying often costs less over time, while leasing spreads the cost. Compare the total you would pay over the full lease term with the purchase price, and check what happens if you want to leave early.
