How to Choose a POS System: Square vs Shopify POS vs Clover vs Lightspeed
Your point of sale system does far more than take payments. It tracks stock, records sales, stores customer details and connects to your accounting. Choosing the wrong one can lock you into fees and workarounds for years. Here is how four popular options compare, and how to decide which fits your business.
Key takeaways
- Start with how you sell: counter service, table service, online plus in-store or appointments.
- Compare the total cost: payment processing, software plans, hardware and add-ons, not just the headline rate.
- Square, Shopify POS, Clover and Lightspeed each have different strengths and lock-in trade-offs.
- Features, prices and availability change often and vary by country, so confirm current details directly with each provider.
A point of sale (POS) system is the combination of software and hardware you use to ring up sales and take payments. Modern systems run on tablets, phones or dedicated terminals and sync to the cloud, so you can check sales and stock from anywhere.
Because the POS sits at the center of daily operations, switching later is painful. Product data, customer records and staff habits all need to move. It pays to spend a few hours choosing carefully now. This comparison describes four widely used options in general terms. Plans, fees and features change frequently, and not every product is offered in every country, so treat this as a starting point and verify the details on each provider's website before you commit.
Step 1: Define what you need
Different businesses need very different things from a POS. Write down your answers to these questions before you look at any product:
- How do you sell? Quick counter sales, table service, appointments, events, or a mix of in-store and online?
- How complex is your stock? A few dozen items, or thousands of products with sizes, colors and suppliers?
- How many locations and staff? Will you need permissions, shift tracking or multi-store reporting?
- What must it connect to? Accounting software, an online store, a booking system, a loyalty program or delivery apps?
- What is your sales volume? This determines how much processing fees matter and whether custom rates are possible.
Common mistake
Choosing on the card processing rate alone. A low rate is attractive, but monthly software fees, add-on modules, hardware costs and contract terms can outweigh a small difference in processing. Model your total monthly cost using your own sales figures before deciding.
The four systems at a glance
Here is a general picture of how each system is typically positioned. All four are established, widely used platforms, and each can work well for the right business.
Square
Square, owned by Block, is known for its quick setup and its approach of letting very small sellers start with basic software and a simple card reader. It offers versions aimed at retail, restaurants and appointment-based businesses, plus online store tools. It tends to suit new businesses, market sellers, cafes and service providers who want to start quickly. Payment processing is generally handled by Square itself, so you use its rates rather than shopping around.
Shopify POS
Shopify POS is the in-person selling side of the Shopify e-commerce platform. Its main strength is a single system for products, stock and customers across an online store and physical locations. It suits retailers who sell significantly online, or plan to, and want their shop and website kept in sync. It is less focused on table-service restaurants.
Clover
Clover is owned by Fiserv, one of the large payment processing companies. It is known for its range of dedicated hardware, from countertop stations to handheld devices, and an app market for extra features. Clover is often sold through banks and resellers, so pricing and contract terms can vary depending on who you buy from. Read the agreement carefully.
Lightspeed
Lightspeed offers separate products for retail and hospitality, with an emphasis on advanced inventory, multi-location management and reporting. It tends to suit established retailers with large or complex catalogs, and restaurants and bars that need detailed floor and menu management. It is usually priced as a monthly subscription and may be more than a very small business needs.
| System | Often a good fit for | Key strength | Things to check |
|---|---|---|---|
| Square | New and small businesses, cafes, services | Fast setup, low entry cost | Processing rates, costs of paid add-ons as you grow |
| Shopify POS | Retailers selling online and in store | Unified online and in-store stock | Plan levels, payment options in your country |
| Clover | Shops and restaurants wanting dedicated hardware | Hardware range and app market | Reseller contract terms, hardware ownership |
| Lightspeed | Larger catalogs, multi-location, hospitality | Advanced inventory and reporting | Subscription cost, setup and training time |
Pro tip
Ask other business owners in your industry and area what they use and what they would change. A local cafe owner or shop owner can tell you about real support response times, hidden fees and the features they actually use, which no feature list will show.
Understand the real costs
POS pricing usually combines several elements. Make sure you understand each one before comparing options.
- Payment processing fees: usually a percentage of each sale, sometimes plus a fixed amount, with different rates for in-person, online and manually keyed payments.
- Software subscription: a monthly fee per location or per register, with higher tiers unlocking more features.
- Hardware: card readers, terminals, tablets, receipt printers, cash drawers and barcode scanners, bought outright, financed or leased.
- Add-ons: loyalty, advanced reporting, staff scheduling, online ordering and integrations can each carry extra fees.
- Contract terms: length of commitment, cancellation fees and what happens to leased hardware if you leave.
Example
Suppose a small gift shop takes most of its sales in person and wants to launch a simple online store. It lists its monthly card sales, average transaction size and the share it expects online. For each system, the owner adds up processing fees on those sales, the software plan she would need for inventory and an online store, and the cost of a terminal, a receipt printer and a barcode scanner spread over three years. The system with the lowest headline rate turns out not to be the cheapest once the needed software tier is included.
Features worth comparing
Once you have a shortlist, compare the features that matter for your type of business. Ignore the long lists of extras you will never use.
For retailers
- Inventory tracking with variants such as size and color
- Low-stock alerts and purchase orders to suppliers
- Barcode scanning and label printing
- Sync with an online store
- Customer profiles, loyalty and gift cards
For restaurants and cafes
- Table and floor plan management
- Kitchen display or printer integration
- Menu modifiers, courses and split bills
- Tips handling and staff tip reporting
- Online ordering and delivery app connections
For every business
- Offline mode, so you can keep taking payments if the internet drops
- Integration with your accounting software
- Staff accounts with permissions
- Clear reports on sales, margins and best sellers
- Easy data export, so you are not trapped if you switch later
Signs of a good fit
- It handles your main way of selling without workarounds
- Your total monthly cost is clear and predictable
- Staff can learn the basics in an hour
Red flags
- Long contracts with steep cancellation fees
- Hardware that only works with one processor and cannot be reused
- No easy way to export products and customer data
Questions to ask before you sign
Whether you talk to a sales representative, a reseller or a support chat, these questions quickly reveal how a provider will treat you after the sale. Write the answers down so you can compare them side by side.
- What exactly will I pay each month at my sales volume, including every add-on I need?
- Can processing rates or subscription prices change during the contract, and how much notice do I get?
- Who owns the hardware, and can it be used with another system if I leave?
- How quickly are funds from card sales deposited into my bank account, and is faster access an extra charge?
- What happens to my data if I cancel, and in what format can I export it?
- How are chargebacks and disputed payments handled, and are there fees?
- What support is included, and is phone support available during my trading hours?
- How long does a typical setup take for a business like mine?
Vague or evasive answers to any of these are a warning sign. A provider confident in its terms will usually put them in writing without hesitation.
How to make the final decision
- Shortlist two or three systems. Use your needs list to rule out those that clearly do not fit your industry or size.
- Calculate total monthly cost. Use your actual sales volume and the plan tier you would really need.
- Test before committing. Use free trials or demos, enter a few real products and run a mock sale with a staff member.
- Check support. Find out how support works, its hours and whether it is available in your time zone and language.
- Read the contract. Look for length, cancellation fees, hardware ownership and rate change clauses.
- Plan the switch. Schedule setup for a quiet period, import products, train staff and keep the old system available briefly as a backup.

Frequently asked questions
Which POS system is best for a small business?
There is no single best system. A new cafe or market seller may value quick setup and low entry costs, while a multi-store retailer may need advanced inventory. Match the system to how you sell and what you need it to connect to.
Can I use my own payment processor?
It depends on the system and your country. Some POS providers require you to use their own payment processing, while others allow third-party processors. Ask directly, because it affects your fees and flexibility.
Should I buy or lease POS hardware?
Buying usually costs less over time and keeps you flexible if you switch systems. Leasing spreads the cost but can be expensive and may tie you to a contract. Check whether the hardware works only with one provider.
How hard is it to switch POS systems later?
It is manageable but takes planning. Product lists, customer data and sales history need to be exported and imported, and staff need retraining. Choosing a system with good export tools from the start makes any future move easier.
