Deep-Dive Reviews: Each System Explained

1. Square POS — Best Overall for Small Business

Square has dominated the small business POS space since 2009 for good reason: it removes every barrier to entry. There’s no monthly software fee on the base plan, no long-term contract, and the free card reader ships to your door within days. For most small businesses just getting started — or those that simply want something that works without surprises — Square is the default right answer.

What we love:

Free POS software for retail, restaurants, and appointments — three separate apps, all included
No contracts — cancel anytime, no penalties
500+ third-party integrations (accounting, loyalty, payroll, delivery)
Excellent offline mode — keeps processing even when your internet drops
Built-in free online store with every account

What to watch out for:

Account holds: Square is a payment aggregator, not a dedicated merchant account. High-volume spikes or certain industries can trigger automatic fund holds. This is the #1 complaint from Square users. If you process large individual transactions frequently, consider a dedicated merchant account instead.
Flat-rate pricing becomes expensive at high volume — at $20K/month, you’d save $150–$300/month by switching to interchange-plus
Customer support is chat/email only on free plan — phone support requires Plus plan ($29/mo)

Hardware lineup: Square Reader ($49), Square Stand ($149), Square Terminal ($299), Square Register ($799). All hardware is owned outright — no lease traps.

2. Shopify POS — Best for Online + Physical Selling

If you have — or plan to have — any online sales, Shopify POS is in a class of its own. Its unified inventory system means you never oversell a product, and your customers get one consistent experience whether they shop online or in your store. The POS software itself is free, but it requires a Shopify subscription starting at $39/month.

What we love:

True omnichannel: one inventory pool, one customer database, one reporting dashboard
Best-in-class online store builder included
No transaction fees if you use Shopify Payments
Excellent staff management and permissions
Strong loyalty and discount engine

What to watch out for:

Requires a Shopify subscription — not truly free
If you use a third-party payment processor, Shopify charges 0.5%–2% transaction fee
Less ideal for restaurants (Toast or Square for Restaurants is better)
Advanced POS features require Shopify POS Pro ($89/mo per location)

Best for: Any business selling both online and in-person. Boutiques, apparel, specialty food retail, health and beauty.

3. Clover POS — Good Hardware, Serious Contract Risk

Clover hardware is genuinely beautiful — the Flex, Station Duo, and Mini are among the most professional-looking POS setups available. And if you buy directly from Clover.com at published rates, it’s a competitive option for established businesses. The problem is how Clover is often sold.

Clover is distributed through hundreds of bank resellers and independent sales organizations (ISOs), and these resellers frequently bundle Clover hardware with processing contracts of 2–3 years with early termination fees of $500–$2,000+. Merchants who signed through their bank often discover the actual processing rate is far higher than the “2.3%+10¢” advertised on Clover’s website.

⚠️ Clover Contract Warning: Before signing any Clover agreement, confirm: (1) Are you buying from Clover.com directly? (2) What is your actual processing rate in writing? (3) Is there a contract term and what’s the ETF? Hundreds of merchants have reported $3,000–$12,000 exit costs from contracts they didn’t fully understand.

Who should consider Clover: Established businesses buying hardware directly from Clover.com, comfortable with their published pricing, who want premium-looking hardware for a customer-facing environment.

Who should avoid Clover: Anyone being offered Clover through their bank, a third-party sales rep, or any channel that isn’t Clover.com directly.

4. Toast POS — Best for Restaurants (Not General Small Business)

Toast is built exclusively for food service, and it shows. The kitchen display system, table mapping, tip management, online ordering, and delivery integrations are best-in-class. For a full-service restaurant, QSR, or food truck, Toast has no equal.

However — if you’re not in food service, Toast is not for you. The software doesn’t handle retail inventory, and the hardware is restaurant-grade (meaning durable but overkill for non-restaurant use). The starter plan is free, but most restaurants end up on the $69–$165/month Point of Sale plan, and hardware kits run $627–$1,024+.

Best for: Full-service restaurants, QSR/fast casual, bars, food trucks, bakeries, cafes with table service.

Not for: Retail, service businesses, pop-ups, anyone not in food service.

5. Lightspeed POS — Best for Established Retailers with Complex Inventory

Lightspeed Retail is the most powerful inventory management system in the POS space. If your business handles hundreds of SKUs, product variants (size/color/style), purchase orders, vendor management, or multiple locations, Lightspeed handles it all with precision that Square simply can’t match.

The tradeoff is cost: plans start at $89/month, and the full-featured plan with analytics runs $269/month. For a startup or low-volume retailer, that’s hard to justify. But for an established boutique, bike shop, or sporting goods store processing $50K+/month, Lightspeed’s analytics and inventory tools can pay for themselves.

Best for: Established retailers, specialty stores, bike/ski shops, wine shops, businesses with complex inventory or multi-location needs.

6. Helcim — Best for High-Volume Businesses ($10K+/mo)

Helcim uses interchange-plus pricing — the wholesale cost of card processing plus a small markup — instead of the flat-rate model used by Square, Shopify, and others. At low volumes, the difference is minimal. At $10,000/month and above, interchange-plus typically saves $100–$200/month.

There’s no monthly fee, no contracts, and Helcim’s fee automatically decreases as your volume grows (a feature called “Helcim Fee Saver”). The POS software is functional but not as polished as Square or Shopify. Hardware is limited to a single card reader ($109) and smart terminal ($329).

Best for: Established businesses processing $10K+/month who want to minimize processing costs. Service businesses with predictable, recurring revenue. Businesses comfortable with a simpler POS interface in exchange for lower rates.

7. PayPal Zettle — Best for Occasional/Pop-Up Sellers

PayPal Zettle is the simplest POS option available. If you already have a PayPal account, setup takes about 10 minutes. The card reader is $29. The processing rate (2.29%+9¢) is actually slightly lower than Square’s. For someone selling at a farmer’s market, craft fair, or occasional pop-up, it’s the easiest on-ramp.

The critical limitation: PayPal Zettle has no offline mode. If your internet drops, you cannot accept card payments. For any permanent retail location, this is a dealbreaker.

Best for: Pop-ups, markets, seasonal sellers, businesses that already live in the PayPal ecosystem.

Not for: Any location where internet reliability matters.

Real Monthly Cost: What You’ll Actually Pay

Advertised rates never tell the full story. Here’s what you’ll realistically pay per month at three volume levels, including software, processing, and typical hardware amortization:

POS System	At $5K/mo volume	At $10K/mo volume	At $20K/mo volume
Square (free plan)	~$140	~$270	~$530
Shopify POS (Basic)	~$160	~$280	~$540
Helcim	~$115	~$210	~$390
Lightspeed (Core)	~$230	~$360	~$620
Toast (Starter)	~$145	~$275	~$535

Estimates include software fees + processing fees at typical card mix. Does not include hardware, which is a one-time cost. Actual interchange costs vary by card type.

Who Should NOT Use Each System

Square: High-volume businesses ($20K+/mo) paying premium flat-rate fees; businesses prone to account holds (CBD, firearms, adult products, high-ticket items)
Shopify POS: Businesses with no online component and tight budgets (the subscription adds up); restaurant operators (use Toast or Square for Restaurants instead)
Clover: Anyone who can’t verify they’re getting published rates; businesses that might need to exit quickly; startups with unpredictable volume
Toast: Any non-restaurant business — full stop
Lightspeed: New or low-volume businesses where the $89–$269/mo fee isn’t justified by features
Helcim: Very low-volume sellers (under $5K/mo) where flat-rate simplicity is more valuable than marginal savings
PayPal Zettle: Any permanent location where internet reliability isn’t guaranteed; businesses that need robust reporting or inventory management

Frequently Asked Questions

What is the best POS system for a small business just starting out?

Square is the best POS system for most small businesses just starting out. It has no monthly software fee, no contract, works for retail, restaurants, and services, and includes a free online store. The free card reader gets you accepting payments within 24 hours.

How much does a POS system cost for a small business?

POS system costs vary widely. Software can be free (Square, Helcim) to $269/month (Lightspeed). Hardware runs $49–$1,149 one-time. Processing fees are typically 2.3%–2.6% per transaction for flat-rate systems, or interchange-plus rates (averaging 1.7%–2.0%) for volume-based pricing. A typical small business processing $10K/month pays $200–$360 total per month in all-in POS costs.

Is Square still the best POS in 2026?

Square remains the best all-around POS for most small businesses in 2026, especially for startups and businesses processing under $10,000/month. Its combination of free software, no contract, and broad feature set is unmatched at the price point. However, established businesses with higher volume increasingly find Helcim’s interchange-plus pricing saves them $100–$300/month.

What POS system has the lowest processing fees?

Helcim typically has the lowest effective processing fees for businesses doing $10,000+/month, thanks to interchange-plus pricing that averages around 1.9% all-in. For lower volumes, flat-rate systems like Square (2.6%+10¢) and PayPal Zettle (2.29%+9¢) are simpler and competitively priced. Clover advertises 2.3%+10¢ directly, but rates through resellers are often significantly higher.

Can I use a POS system without a monthly fee?

Yes. Square, Helcim, and PayPal Zettle all offer POS software with no monthly fee. You only pay processing fees when you make a sale. Square’s free plan is the most feature-rich free POS available, including inventory management, employee management, and a free online store.

What is the best POS system for a restaurant?

Toast is the best POS system for full-service restaurants in 2026. Its kitchen display system, table management, online ordering, and tip handling are purpose-built for food service. For simpler restaurant setups (cafes, food trucks, QSR), Square for Restaurants offers a free plan that handles the basics well without Toast’s higher hardware and software costs.

What should I look for when choosing a POS system?

The five most important factors when choosing a POS system are: (1) Contract terms — avoid long-term commitments until you’re confident in the system; (2) Total cost — software + processing fees + hardware, not just the advertised rate; (3) Industry fit — restaurant, retail, and service businesses have different needs; (4) Integration ecosystem — can it connect to your accounting software, loyalty program, and e-commerce platform?; (5) Support quality — what happens when something breaks during your busiest hour?

How to Choose the Right POS System (Step-by-Step)

Step 1: Define your business type

Retail, restaurant, service, and online businesses have different POS requirements. Restaurant operators need table mapping and kitchen displays. Retailers need inventory variants and purchase orders. Service businesses need appointment booking and invoicing. Start here before comparing features.

Step 2: Estimate your monthly processing volume

Your monthly card processing volume determines whether flat-rate or interchange-plus pricing makes more sense. Under $5,000/month: flat-rate (Square, Zettle) is simpler. Over $10,000/month: interchange-plus (Helcim) typically saves money.

Step 3: Evaluate contract terms before anything else

Before you fall in love with hardware or features, read the contract. Are you locked in for 1, 2, or 3 years? What’s the early termination fee? For most small businesses, month-to-month flexibility is worth prioritizing — especially in the first year.

Step 4: Calculate total monthly cost

Add software fee + (volume × processing rate) + hardware amortization. This gives you the true monthly cost to compare apples-to-apples. A “free” POS with a 2.7% rate costs more than a $29/mo POS with a 2.2% rate once you’re doing $5,000+/month.

Step 5: Test before committing

Square, Shopify POS, and Helcim all offer free trials or free accounts. Download the app, enter your products, and run a test transaction with a card reader before committing to hardware or a plan. The “right” POS is the one your team can actually use without friction.
