Best POS and Inventory Management Software in 2026: 8 Tools Compared

#1

Square

Best for: Small businesses that want a capable POS with no monthly software fee

Visit squareup.com

Square is the default starting point for a reason: the POS software costs nothing. The Free plan covers the POS app, item library with inventory tracking, invoicing, bookings, and checking and savings accounts, and you only pay when you take a payment. Paid tiers (Plus, Premium) add advanced POS features, lower processing fees, loyalty, and marketing; Pro is custom-quoted for businesses processing over $250,000 a year. Hardware ranges from a $59 reader to full registers, with installment plans available.

The math to watch is processing, not software. At low volume the free software wins easily; as volume grows, the paid tiers' lower processing fees can pay for themselves, and high-volume sellers should get the Pro quote. Restaurant-specific depth (kitchen display at $20 to $30 per device per month, kiosk at $30 to $50) is where the bill grows, so restaurants comparing against Toast should price the full stack, not just the base plan.

Shopify POS

Best for: Retailers selling both online and in person on one inventory

Visit shopify.com

Shopify POS exists for one customer: the retailer whose online store and physical store must share the same inventory. POS Lite comes with Shopify plans and covers the essentials; POS Pro adds the retail-grade features (smart inventory management, staff roles, advanced reporting) at a per-location fee. The pitch is unified commerce: sell in store, online, on social and at pop-ups with one back office, one customer record and one set of analytics, with hardware from handheld readers to full counter setups.

The catch is the stack. You need a Shopify subscription underneath, and POS Pro bills per location, so a five-store chain pays five times the add-on. Shopify runs switch incentives (free hardware and discounted subscriptions for annual POS Pro), so never pay list without asking about current offers. If your business is online-first with a store attached, this is the natural pick. If you have no online store, compare the total against Square Free first.

Lightspeed

Best for: Retailers with complex, multi-location inventory operations

Visit lightspeedhq.com

Lightspeed is the inventory-first POS. Where Square and Shopify start from payments and add inventory, Lightspeed starts from the stockroom: purchase orders, vendor management, multi-location transfers, matrix inventory for sizes and colors, and automated reordering, with the POS and ecommerce riding on top. It serves retail, restaurant and golf verticals, with industry-specific builds (a bike shop POS that understands service orders, a garden center POS with advanced tracking) rather than one generic register.

That depth is the reason to choose it and the reason to pause. Businesses with 10,000 SKUs across locations get real value; a single boutique does not need it and will pay in complexity. Pricing is quote-only, so get the per-location monthly fee, the payments rate and the onboarding cost in writing. Lightspeed also offers funding inside the POS for eligible businesses, which is unusual and worth knowing about if cash flow is tight.

#4

Toast

Best for: Restaurants that want a system built only for restaurants

Visit pos.toasttab.com

Toast is the restaurant industry's POS the way Square is retail's default. Everything is built for the floor: table management, coursing, kitchen display systems, handhelds for tableside ordering, online ordering with delivery integrations, payroll, scheduling and gift cards with zero load fees. The company states 180,000 locations on the platform, and its own comparison page puts entry-level software at $69 per month with $0-per-month options on the pay-as-you-go plan (software and processing fees still apply; an $85 monthly inactivity fee may apply).

The honest catch is the total bill. Toast's own site prices the software; the hardware (Toast Flex terminals, Go handhelds), the xtraCHEF inventory add-on and the processing fees are separate lines. Restaurants should get the complete quote: software tier, hardware package, xtraCHEF, and the processing rate. Toast IQ (AI analytics) is now included at no extra cost, which is a genuine differentiator for operators who want menu and labor insights without a data analyst.

#5

Clover

Best for: Businesses that want flexible hardware and a deep app market

Visit clover.com

Clover (from Fiserv) is the hardware-flexibility pick. The device range covers countertop (Station Duo), portable (Flex) and pocket (Mini) form factors, with kitchen display and self-order kiosk options, and the app market lets a business add exactly the features its vertical needs: online ordering, loyalty, employee management, gift cards. It is genuinely strong in both restaurants and retail, which few systems manage.

The buying experience is the catch. Clover sells through banks and independent resellers, and the reseller sets the pricing, contract length and sometimes the support experience. Two businesses can buy the "same" Clover system on very different terms, and early termination fees are the complaint that recurs in reviews. Get the full fee schedule, the contract length and the termination terms in writing from your specific reseller before signing, and confirm who provides support: the reseller or Clover directly.

#6

SpotOn

Best for: Restaurants that want online ordering, marketing and labor tools bundled with the POS

Visit spoton.com

SpotOn built its name as the restaurant POS that bundles what Toast sells as add-ons. The Core Bundle wraps the POS with commission-free online ordering, automated marketing, reservations, labor management (SpotOn Teamwork: scheduling, tip distribution, payroll integration) and AI-powered P&L analysis (Profit Assist). The vendor states software plans start at $0 per month with competitive processing rates, and publishes G2 badges rating it the top restaurant POS across recent quarters.

For an independent restaurant, the bundle math is the selling point: one monthly package instead of five separate subscriptions for ordering, marketing, scheduling and reporting. The counterpoint is the same as any bundle: price the Core Bundle against Toast's software plus only the add-ons you would actually buy, because an unused bundle feature is still a cost. Ask for the processing rate in writing; that is where the real money moves.

#7

Epos Now

Best for: Retail and hospitality businesses that want to buy the complete hardware and software bundle upfront

Visit eposnow.com

Epos Now takes the opposite approach from the free-software vendors: buy the system. The homepage advertises the complete POS system (terminal, printer, card machine, software) from $399 one-time plus $84 per month, with frequent promotions discounting the hardware further. It covers retail (clothing, grocery, gift shops) and hospitality (pubs, restaurants, cafes) with inventory management, real-time reporting, staff management and hundreds of integrations for payments, accounting and delivery apps.

This model suits businesses that prefer owning the hardware and knowing the monthly number. The tradeoff is the upfront check and the fact that the headline promo price moves constantly ("lowest price ever" banners with countdown timers are a permanent fixture). Get the current offer in writing with the hardware list, and ask what the monthly fee covers versus which integrations cost extra. For a new shop that wants one purchase and one support number, the bundle is genuinely simple to evaluate.

#8

Zettle by PayPal

Best for: Mobile, market and pop-up sellers already in the PayPal ecosystem

Visit zettle.com

Zettle (formerly iZettle, owned by PayPal) is the mobile seller's POS. The pitch is simplicity: a card reader, the POS app, and your phone become a complete checkout with product library, basic inventory tracking and sales reports, and money flows into the PayPal ecosystem you may already use for online sales. For markets, pop-ups, food trucks and services sold on the go, that is often all the POS a business needs.

It is not an inventory management system in the Lightspeed sense: multi-location stock, purchase orders and deep reporting are beyond its brief. Pricing is region-specific (the homepage opens a country selector), so check your country's Zettle site for the reader price and the per-transaction fee before comparing. If you already process through PayPal and sell mostly on the move, Zettle keeps everything in one place. If you run a stocked store, start with the systems above.
