Best POS Systems for Retail Stores in 2026: Checkout, Inventory and Barcode Scanning

The best POS system for retail is the one that keeps the till, the stockroom and any online store counting the same stock. Lightspeed and Shopify are built around that idea for retailers who sell in more than one place, Square POS is the card-reader-first choice for a single shop, and Open Source POS and Odoo are the self-hostable options with barcode, tax and inventory features.

Very few tools in Enlisted's catalogue are built for retail alone: Square, Lightspeed and Clover also serve restaurants and services, and the open-source options are general business software. The list below groups them by job: hardware-and-payments packages, online-plus-store selling, open source, phone-based apps for small shops, and inventory tools that sit behind a till.

How we picked

Enlisted kept tools whose descriptions name retail shops, stores or stock control, or whose point of sale lists checkout, inventory and receipts as core jobs. Each listing shows its licence, whether it can be self-hosted, its pricing model and, for open source, GitHub activity, all from the directory. Descriptions are drawn from vendor sites and documentation rather than from running the products. Two tools, Brightpearl and Zoho Inventory, are not registers at all; they are included because inventory is usually the second half of a retail decision. See how Enlisted ranks tools.

What should a retail store check before choosing a POS?

Retail decisions tend to turn on stock, not on the checkout screen. These are the points worth confirming on a vendor's own pages.

• Whether the till and the online store share stock. Shopify's POS page says inventory updates with every sale and stays in sync across locations, online and in person. Lightspeed lists inventory visibility across locations and channels. Odoo describes click-and-collect for online orders. A standalone register needs a connector or a second system for this.
• How items get scanned and labelled. Odoo says it syncs with barcode scanners and scales. TinyPOS reads barcodes and QR codes with the phone camera, KitaTracker scans barcodes for lookup and checkout, and Open Source POS generates barcodes. If products arrive without barcodes, a label tool such as UPCgen creates UPC and EAN codes with valid check digits.
• Purchasing and suppliers. Lightspeed's retail page mentions ordering stock for any location and wholesale ordering from brands. Open Source POS keeps supplier records, and Zoho Inventory handles purchase orders. Ask whether stock received is posted automatically.
• Tax rules. Open Source POS describes multi-tier taxation including VAT and GST, and Kassenmeister covers German TSE and GoBD requirements. If your country has fiscal-printer or reporting rules, check that the vendor supports them before comparing features.
• Who takes the card payment. Square, Zettle and Clover sell card hardware with their software. TinyPOS records payment types but says it does not process payments itself, and Open Source POS's own site does not mention card processing. Decide up front how cards will reach your bank.

Best retail POS systems with payments and hardware in one package

These are hosted, closed-source products that sell card hardware alongside the software. Square POS is the only one in this group with a free plan.

1. Square POS: best for a single shop that wants a free plan and card readers

Square Point of Sale is register software and card-payment hardware that Square groups by business type, with a retail setup that includes inventory tracking. Beyond taking payments it covers managing orders, scheduling and paying staff, invoices, an online store and cash-flow views, and the hardware range runs from handheld devices and terminals to registers, stands, kiosks and card readers.

A free plan, a free trial and paid tiers are listed. If you later want a website, Square Online connects web selling to the same payments and hardware. The vendor's own Square listing describes the wider payments business.

• Best for: an independent shop that wants to start on a free plan and add hardware as it grows.
• Watch out for: Enlisted's data gives little detail on purchase orders or multi-location stock transfers, so check those if you run more than one store.

2. Lightspeed: best for multi-store retailers that care about inventory

Lightspeed is point-of-sale and commerce software for retailers, restaurants and golf courses, and its retail customers range from apparel and electronics to liquor, pet and sporting goods stores. The retail suite lists point of sale, payments, ecommerce, wholesale, inventory management, marketing, analytics, scanners and hardware, and an API.

The retail page puts stock first: visibility across locations and warehouses, transfers between locations, and ordering stock for any location from one place. It says it connects with accounting software, ERP systems and marketing tools. The Lightspeed listing has the rest.

• Best for: retailers with several stores or an online channel who need stock visibility across all of them.
• Watch out for: it is closed source with no free plan or free trial listed, and Enlisted's listing does not describe offline behaviour, so ask how the till copes when the connection drops.

3. Clover: best for shops that want terminals and software from one vendor

Clover is a point-of-sale and payments system for small businesses that combines hardware terminals with software for taking orders, accepting payments and running daily operations. It is organised into food and beverage, retail and services versions, and its listed hardware includes the Mini, Flex, Station Duo and a self-service kiosk.

For retail, Enlisted's listing describes in-person payments rather than a detailed feature list, so ask Clover for the retail inventory and reporting specifics. Clover belongs to the payments company Fiserv, and the Clover listing shows its pricing model.

• Best for: shops that want one vendor for countertop devices, software and payments.
• Watch out for: the vendor pages Enlisted summarises say more about hardware and payments than about retail stock control, and there is no free plan.

4. Zettle: best for small shops and market stalls that want a card reader first

Zettle is the card reader and point-of-sale system from PayPal, made for small businesses that sell face to face. It accepts card, contactless and mobile payments, organises inventory and analyses sales from one system, and pairs readers and terminals with the software.

PayPal runs country-specific Zettle sites for the United States, the United Kingdom, Sweden, Norway, Denmark, Finland, France, Germany, the Netherlands, Spain, Italy, Mexico and Brazil, each with local register and reader options. Enlisted lists pricing as per transaction rather than a monthly plan. See the Zettle listing.

• Best for: small shops, markets and pop-up sellers who mainly need to take card payments and track a modest catalogue.
• Watch out for: it is built around in-person selling, so it is not an online-store platform, and available hardware depends on your country site.

Best when the online store comes first

5. Shopify: best for retailers selling online and in the shop

Shopify is a hosted commerce platform for building online stores that also sells in person with point of sale. Selling channels include the online store, in-person POS, the Shop app, social platforms and marketplaces, and the platform covers checkout, payments and taxes, orders and inventory, shipping and workflow automation.

On its POS page Shopify describes countertop or mobile hardware, staff permissions and selling at pop-ups and markets, with one inventory across locations. It lists a free trial but no free plan. For comparisons beyond retail, read the Shopify alternatives guide and the best ecommerce platforms roundup.

• Best for: retailers whose online store is the main channel and who want the shop counter to draw from the same stock.
• Watch out for: it is closed source with no self-hosted option, and the POS page does not mention offline selling, so ask about that.

Best open-source and self-hosted retail systems

All three are free software you can run yourself, but they differ a lot in scope. The ecommerce category and ERP category list more.

6. Open Source POS: best self-hosted register for a small shop

Open Source POS is a web-based point of sale written in PHP that stores its data in MySQL or MariaDB. It covers stock for items and kits, VAT, GST and multi-tier taxation, a sale register with transaction logging, quotations and invoicing, expenses, cash-up, printed and emailed receipts, barcode generation, customer and supplier databases, gift cards, rewards and reports, with multi-user permissions.

On licensing, the project's homepage points to MIT terms plus a rule that its footer signature must remain visible, and its wiki lists supported receipt printers and barcode scanners. The code is on GitHub; see the listing for recent activity.

• Best for: a single small shop with someone able to run a PHP and MySQL server.
• Watch out for: the site does not describe card processing or offline selling, so settle how you would take cards and what happens when the connection drops.

7. Odoo: best open-source suite when inventory and ecommerce go with the till

Odoo is a bundle of open-source business apps that run in the browser, including point of sale, inventory, ecommerce and accounting, usable alone or together as an ERP. Odoo's shop POS page describes syncing with barcode scanners and scales, loyalty programs with points, rewards and gift cards, multi-store support, printing invoices on the fly and letting customers order online and pick up in store. It also says payments made offline sync when you reconnect.

Self-hosting is possible, a hosted service is sold too, and one app is free; the Odoo listing has the details.

• Best for: retailers who want inventory, ecommerce and accounting in the same system as the register.
• Watch out for: GitHub lists the licence as Other, so read the terms, and paid hosted plans are priced per user.

8. ERPNext: best free ERP whose POS posts straight to stock and accounts

ERPNext is a free, open-source ERP built on the Frappe framework, covering accounting, inventory, orders, manufacturing, assets and projects. Its POS documentation says it integrates retail transactions with inventory and accounting, updates stock levels in real time, supports several payment methods and loyalty programs, and includes built-in reporting.

It is GPL-3.0 licensed and free to self-host, with a paid hosted option through Frappe Cloud. See the ERPNext listing.

• Best for: a retailer who already wants a full ERP and accounting system behind the till.
• Watch out for: the POS documentation page does not mention offline use or barcode scanning, so confirm both, and an ERP is a heavy tool if you only need a register.

Best lightweight apps for small shops

9. TinyPOS: best offline-first app for kiosks and small shops

TinyPOS turns a phone or tablet into a simple point of sale for kiosks, market stalls, pop-up shops, coffee carts and independent retailers. Its core selling, inventory, checkout, receipt and reporting features run on the device without a required account or a constant connection, on iPhone, iPad and Android.

Products can be added by hand or scanned with the camera, inventory tracks stock and low-stock items, and receipts can be shared or printed on compatible Bluetooth thermal printers. The developer's TinyPOS page says it does not process payments itself; it records cash, card or transfer sales. See the TinyPOS listing.

• Best for: very small shops and solo sellers who want a simple, offline-capable register.
• Watch out for: you need a separate way to take card payments, and it is not designed for multi-store retail.

10. KitaTracker: best iPhone and iPad app for shops replacing paper notebooks

KitaTracker is an iPhone and iPad app that combines checkout and stock records for small local businesses, with a Philippines focus noted in its description. It records transactions, scans barcodes, deducts stock automatically after each sale, alerts on low and out-of-stock items and shows profit reports.

At checkout it supports percentage or fixed discounts and cash, card, e-wallet, bank transfer or credit payments, tracks partial payments and unpaid customer balances, and prints receipts on Bluetooth thermal printers. Product variants, loyalty points and an online storefront link are also listed.

• Best for: owners of small local shops who currently run on paper notebooks or spreadsheets.
• Watch out for: it is Apple-only, closed source and focused on small Philippine businesses. See the KitaTracker listing.

Best when stock control is the harder problem

Some retailers find the register easy and the stockroom hard. These two sit behind a till rather than replace one.

11. Brightpearl: best retail operating system for multichannel sellers

Brightpearl is a retail operating system for retailers and wholesalers that centralises inventory forecasting and purchasing, order management, shipping, warehouse management, CRM, retail accounting and analytics. It lists integrations with Shopify, Magento, BigCommerce, Amazon, eBay and Walmart on the sales side, and Square, Stripe, Xero, QuickBooks and Sage among payment and accounting tools.

• Best for: multichannel brands and wholesalers replacing spreadsheets and disconnected apps.
• Watch out for: Enlisted's listing does not list a point of sale among its modules, and pricing is by contacting sales. See the Brightpearl listing.

12. Zoho Inventory: best for adding purchase orders and multichannel stock to a small shop

Zoho Inventory is online inventory and order management software for small businesses and online sellers. It handles purchase orders, multi-warehouse stock with transfers and bin locations, serial and batch tracking, barcode generation and scanning, and multichannel sales orders with invoicing and returns.

• Best for: small retailers outgrowing spreadsheets who need purchasing and stock across channels.
• Watch out for: it is not a register, so you pair it with a POS. A free plan is listed alongside paid tiers, so compare them on the Zoho Inventory listing.

For a deeper look at this layer, see the guide to inventory management software for retail, and for staff rosters the guide to scheduling software for retail.

Retail POS for larger or specialised setups

Three more listings suit narrower cases. Kassenmeister is German-language point-of-sale software with TSE and GoBD compliance for supermarkets, bakeries, butchers, hardware stores, kiosks and fashion shops, with scale support. Priority Software is an ERP vendor for mid-sized businesses with a retail line that covers POS, kiosks and mobile back office. Commerce Layer is a headless commerce API with a POS that uses the same API as online channels, so it needs developers. Enterprise suites such as Manhattan Associates are sold through sales teams.

Which retail POS should you choose?

Shortlist two or three, then check the live pricing section below, which shows plan prices where vendors publish them. Ask each vendor how stock is counted across channels, what the card hardware and processing cost, and what the register does when the connection drops.
