The point-of-sale market for small businesses looks nothing like it did when this guide first ran. Two of the four systems we originally recommended are gone as standalone products: ShopKeep was bought by Lightspeed, and Intuit discontinued QuickBooks Desktop Point of Sale entirely. Meanwhile free-to-start POS software became the norm, card readers got smarter, and a few platforms pulled ahead for specific business types. This is the updated 2026 guide to the best POS software for a small business, with current pricing, honest limitations, and clear picks by what you sell.
Key takeaways
- Square is the default free starting point. No monthly fee to begin, hardware you can buy for a few dollars, and it works for both retail and restaurants.
- Match the tool to what you sell. Toast for restaurants, Shopify POS for online-plus-in-person, Lightspeed for inventory-heavy retail, Clover for flexible hardware.
- Two old favorites are gone. ShopKeep is now part of Lightspeed, and QuickBooks Desktop Point of Sale was discontinued, with Intuit pointing users to Shopify.
- Processing rates matter more than the subscription. At real volume, the percentage per swipe costs far more than the monthly software fee, so compare rates carefully.
- Watch reseller pricing on some systems. Clover in particular is sold through many resellers, and the same hardware can carry very different rates.
What changed in small-business POS since 2015
The biggest shift is consolidation. ShopKeep, one of our original picks, was acquired by Lightspeed in a deal worth around $440 million in 2020, and the ShopKeep brand was folded into Lightspeed Retail. Intuit went further and discontinued QuickBooks Desktop Point of Sale outright, ending sales and steering existing users toward Shopify POS as the recommended replacement. If you are still running either of those, you are on borrowed time and should plan a migration.
The commercial model changed too. In 2015, a paid monthly plan per register was standard. Today the entry tier is usually free, and the vendors make their money on payment processing instead. That makes the processing rate, not the subscription, the number that decides your real cost. Square, Block’s flagship product, popularized this, and most competitors followed.
The best small-business POS systems in 2026
These five cover the great majority of small retail and restaurant needs. Prices below are current list prices for the entry tiers; processing rates are in-person, card-present.
| System | Best for | Starting price | In-person processing |
|---|---|---|---|
| Square | All-around retail & quick-serve | Free; Plus $49/mo per location | 2.6% + 15¢ (free plan) |
| Toast | Restaurants & food service | $0 starter; paid plans by quote | Quoted per business |
| Shopify POS | Online + in-person retail | Basic $39/mo; POS Pro +$89/mo per location | Varies by plan |
| Lightspeed Retail | Inventory-heavy retail | Basic $89/mo | 1.5% card-present (Lightspeed Payments) |
| Clover | Flexible hardware, mixed use | Varies by plan & reseller | Varies by reseller |
Square
Square is still the easiest place for a small business to start. The core software is free, you only pay processing when you take a payment, and you can begin with a reader that costs a few dollars or scale up to a full counter setup. It handles retail and quick-serve well, includes inventory and reporting, and connects to accounting tools like QuickBooks and Xero. Paid plans add features: Square Plus runs $49 per month per location and Premium $149, with processing dropping slightly as you move up, from 2.6% + 15¢ on the free plan to 2.4% + 15¢ on Premium.
Strengths: no barrier to start, transparent pricing, cheap hardware, and one ecosystem for payments, payroll, and lending. Limitations: deep, industry-specific features are lighter than specialists like Toast for restaurants, and processing costs add up once you are doing real volume.
Toast
Toast is the system to beat for restaurants. It is built around food service, with strong kitchen display, online ordering, tipping, and menu management, and hardware designed for a busy kitchen environment. It offers a $0 starter option, with higher tiers quoted per business, and it works as a payment facilitator rather than processing cards itself. For a cafe, bar, or full-service restaurant, its depth in the areas that matter usually outweighs a more general tool.
Strengths: restaurant-specific features no generalist matches, durable hardware, and a free entry point. Limitations: it is only for food service, pricing above the starter tier is quote-based rather than transparent, and contract and hardware terms deserve a close read.
Shopify POS
Shopify POS is the right pick if you sell both online and in person, and it is now the path Intuit recommends to former QuickBooks POS users. Your in-store sales and your online store share one inventory and one customer record, which removes the reconciliation headache of running separate systems. Shopify POS Lite is included with every Shopify plan, which starts at $39 per month for Basic, and POS Pro adds full retail features for $89 per month per location.
Strengths: genuinely unified online and in-person selling, strong inventory across channels, and a large app ecosystem. Limitations: you are committing to the Shopify platform, POS Pro is an added cost per location, and it is weaker for restaurants than Toast or Square.
Lightspeed Retail
Lightspeed is aimed at retailers whose complexity lives in inventory: many SKUs, variants, purchase orders, and supplier management. It absorbed ShopKeep and folded those small-business customers into a more capable retail platform. Pricing starts at $89 per month for the Basic plan with one register, rising to $149 and $289 for more advanced tiers, and Lightspeed Payments offers a card-present rate around 1.5%, which is low if you qualify.
Strengths: best-in-class inventory and purchasing tools, built-in eCommerce, and a competitive processing rate. Limitations: a higher starting price than Square, more system than a simple shop needs, and extra registers and locations cost more.
Clover
Clover, owned by Fiserv, is a flexible hardware-first system with a wide range of countertop and handheld devices and an app marketplace for adding functions. It suits businesses that want dedicated hardware and a mix of retail and service use. The catch is how it is sold: Clover comes through many banks and resellers, and the same device can carry very different software plans and processing rates. Buy it, but compare quotes carefully and read the terms.
Strengths: strong hardware lineup, an app marketplace, and broad availability. Limitations: pricing and processing vary widely by reseller, some plans lock you to a specific processor, and total cost is harder to pin down up front.
What happened to the old picks
Two of the four systems from the original version of this guide no longer stand on their own. ShopKeep was acquired by Lightspeed and its customers were migrated into Lightspeed Retail, so new buyers should look at Lightspeed directly. QuickBooks Point of Sale, which was a costly desktop product with license tiers running well over a thousand dollars, was discontinued by Intuit, which now directs users to Shopify POS. Square and Shopify, the other two originals, both remain strong and appear above with current pricing.
How to choose
Start with what you sell. If you run a restaurant or cafe, Toast is the natural first look, with Square for Restaurants as the lighter, free alternative. If you sell online and in person, Shopify POS keeps both sides in sync. If your business is inventory-heavy retail, Lightspeed earns its higher price. If you just want to start selling with minimal cost and complexity, Square is hard to beat. Then compare processing rates at your expected volume, because a slightly higher percentage per transaction can outweigh any monthly-fee saving once sales grow. Finally, watch for contracts and hardware lock-in, especially on quote-based or reseller-sold systems.
Frequently asked questions
What is the cheapest POS system for a small business? Square, because the software is free and you only pay per transaction. Toast also has a $0 starter option for restaurants. Cheapest to start is not always cheapest overall, so weigh the processing rate against your volume.
Is QuickBooks Point of Sale still available? No. Intuit discontinued QuickBooks Desktop Point of Sale, ended sales, and now recommends Shopify POS as the replacement. If you still use it, plan a migration.
What happened to ShopKeep? Lightspeed acquired ShopKeep in 2020 and merged it into Lightspeed Retail. The ShopKeep name is retired, so new buyers should evaluate Lightspeed directly.
What is the best POS for a restaurant? Toast, for its depth in food service. Square for Restaurants is a strong free alternative for smaller or simpler operations that do not need everything Toast offers.
Does the monthly fee or the processing rate matter more? At low volume the monthly fee dominates, but as sales grow the processing percentage becomes the larger cost. Estimate your monthly card volume and compare total cost, not just the subscription.
The verdict
The small-business POS market matured, and the honest answer now depends on what you sell. Square remains the best default: free to start, easy to run, and capable enough for most retail and quick-serve shops. Toast owns restaurants, Shopify POS owns online-plus-in-person, and Lightspeed owns inventory-heavy retail, while Clover offers hardware flexibility if you shop the reseller quotes carefully. Whatever you choose, compare processing rates at your real volume and read the contract terms before you commit, because those two details decide your true cost long after the setup is done.
