Best POS Systems for Small Business in 2026: Shops, Cafes and Service Businesses

The best POS system for small business depends on what you sell and how you take payment. Square POS is the broadest starting point, with a free plan and setups for food and beverage, retail, beauty and service businesses. Zettle and SumUp are card-reader-first options for market traders and small shops, and Odoo and Open Source POS suit owners who want to run the software on their own server.

"Small business" covers a florist, a cafe and a barber, and their tills have little in common. So the list below is grouped by type of business: simple shops, cafes and food stalls, service businesses, phone-based apps for the smallest sellers, businesses that also sell online, and open-source options. Tools aimed at a single trade have their own guides, linked at the end.

How we picked

Enlisted looked for tools whose own descriptions name small businesses, shops, cafes or service businesses, and kept those where checkout is a core job. Every listing shows the licence, whether it can be self-hosted, its pricing model and, for open source, recent GitHub activity, taken from the directory. Descriptions are based on vendor sites and documentation rather than on using the products. Several well-known names, such as Toast, are covered in the narrower restaurant POS guide instead of here. See how Enlisted ranks tools.

What should a small business check before choosing a POS?

Five questions settle most small-business decisions, and each can be answered from a vendor's own pages.

Pricing models also differ: a monthly plan, a free plan with paid tiers, per-transaction charges, or free open-source software where you pay for hosting. The live pricing section below this guide lists published plans, so use it alongside the processing terms each vendor publishes.

Best for a simple shop: card reader first

These three are hosted, closed-source products built around taking in-person card payments.

1. Square POS: best all-round starting point with a free plan

Square Point of Sale is the register and payments product from Square, used by physical businesses to take payments and track sales. Square tailors it to food and beverage, retail, beauty and personal care, and a broad range of service businesses, and the software side covers orders, inventory, appointments, invoices, an online store, staff schedules and pay, and cash-flow reporting.

Square sells the matching devices: handhelds, terminals, registers, stands, kiosks and readers for contactless, chip and magstripe cards. A free plan and a free trial are listed, with paid tiers above them. See the Square POS listing.

• Best for: a small business of almost any kind that wants one vendor for payments, orders and basic staff tools.
• Watch out for: closed source with no self-hosted option, and the free plan is the entry level of a tiered range, so check what the tier you need includes.

2. Zettle: best for market stalls and pop-ups that pay per transaction

Zettle is PayPal's card reader and till for small businesses that sell in person. Owners accept card, contactless and mobile payments, organise inventory and review sales analytics from one system, and Enlisted lists its use cases as small shops, market stalls and pop-up sellers.

Its pricing is listed as per transaction rather than a monthly plan, and PayPal runs country-specific sites for the United States, the United Kingdom, several European countries, Mexico and Brazil. See the Zettle listing.

• Best for: very small sellers who prefer to pay as they take payments instead of committing to a plan.
• Watch out for: there is no free plan listed and it is closed source; hardware and options vary by country site.

3. SumUp: best for small merchants who want a reader and a simple register

SumUp is a payments company that sells card readers and point-of-sale tools to small merchants. Businesses use the readers with a companion app or a register to take card and contactless payments in shops, at markets and on the move, and Enlisted lists market traders, mobile businesses and small shops moving off cash-only sales as its use cases.

SumUp's own site pairs food and beverage, retail and service businesses with its POS, which it says supports payments, employee management, appointment scheduling and sales tracking.

• Best for: small merchants, from coffee shops to barbers, who want a reader first and add a register later.
• Watch out for: plans, fees and country availability are published by SumUp and not summarised in Enlisted's listing, so confirm them for your country. See the SumUp listing.

Best for cafes and food businesses

4. Clover: best for cafes that want counter and kitchen hardware

Clover is a point-of-sale and payments platform from Fiserv that sells hardware and software together. Its food and beverage version lists online order management, top-selling item reports, staff scheduling and payroll, and tools for turning first-time guests into repeat customers.

Devices include the compact countertop Mini, Flex, Station Duo, a kitchen display and a self-service kiosk, so a cafe can start with one terminal and add a kitchen screen. Retail and service versions exist, and the vendor also has pages for healthcare businesses. See the Clover listing.

• Best for: cafes and counters that expect to grow into kitchen displays or kiosks.
• Watch out for: you buy into Clover's own hardware, and there is no free plan or self-hosted version.

5. Taplo: best for shops and food businesses that want marketing in the same login

Taplo is a business management platform that combines checkout, ordering, SMS and email marketing, loyalty, staff time tracking and reporting. Its checkout side lists tap-to-pay, booking and appointments, a kitchen display, retail checkout, QR ordering, self-service kiosks and online ordering with pickup and delivery. It runs on devices a business already owns and says it works offline.

Marketing and operations tools include SMS campaigns, loyalty, gift cards, reviews, a waitlist, predictive inventory and tip tracking. The vendor says it has no contract and no proprietary hardware. See the Taplo listing.

• Best for: cafes, coffee shops and small shops that want sales, texting and staff hours in one system.
• Watch out for: it is broad, so a business that only needs a till may not use most of it. Closed source, hosted only and no free plan.

6. Canhanf: best for simple counter invoicing at a cafe or small shop

Canhanf is a commercial invoice and order management product designed for cafes and small retail businesses. Its site presents it as a way to speed up checkout and keep stock records in step with what is sold, by creating invoices and orders at the counter.

• Best for: a cafe or small shop that wants counter invoices and stock records without a larger system.
• Watch out for: Enlisted holds little detail beyond that description and lists no pricing, so ask the vendor for specifics. See the Canhanf listing.

Which of these suit service businesses?

Barbers, salons and similar businesses need appointments more than inventory. Square lists appointment scheduling and invoices, SumUp's POS lists appointment scheduling, and Taplo lists booking and appointments. Clover has a services version. If bookings are the main job and payment is secondary, a dedicated tool may serve you better, and the guides to booking software for small business and free scheduling software cover that.

Best phone and tablet apps for the smallest sellers

7. TinyPOS: best for solo sellers who want offline checkout

TinyPOS is an offline-first point-of-sale app for iPhone, iPad and Android aimed at kiosks, market stalls, pop-up shops, coffee carts and independent retailers. Selling, inventory, receipts and reports run on the device without a required account or constant connection, and the camera reads barcodes and QR codes.

The developer's TinyPOS page says it records cash, card or transfer payments for tracking but does not process them. A free tier is listed. See the TinyPOS listing.

• Best for: solo sellers and tiny shops who want a free, simple app with end-of-day totals.
• Watch out for: you must arrange card processing separately.

8. KitaTracker: best iPhone and iPad app for local shops and canteens

KitaTracker is a checkout and stock app for iPhone and iPad, with a Philippines focus noted in its description. Its listing names cafes, bakeries, restaurants, salons, laundry shops, clinics, pharmacies and school canteens, and it can track partial payments and unpaid customer balances, which suits shops that sell on credit.

It scans barcodes, deducts stock after each sale, alerts on low stock and prints receipts and kitchen order tickets on Bluetooth thermal printers. The listing shows a free tier.

• Best for: small local businesses that sell on credit or run on paper notebooks.
• Watch out for: Apple devices only, and written with Philippine businesses in mind. See the KitaTracker listing.

Best when you also sell online or plan to grow

9. Shopify: best for small businesses that also run an online store

Shopify is a hosted commerce platform for online stores that also covers in-person selling with point of sale. On its POS page it describes countertop or mobile hardware, staff permissions and selling at pop-ups and markets, with inventory shared across locations and channels. A free trial is offered, but no free plan.

• Best for: small businesses whose online store matters as much as the shop.
• Watch out for: closed source, and its plans suit stores more than a till-only business. See Shopify alternatives if you are comparing platforms.

10. Lightspeed: best for retail or hospitality businesses growing past one location

Lightspeed sells point-of-sale and commerce software for retail, restaurants and golf courses, covering payments, inventory, ecommerce and reporting. Its retail suite lists multi-location inventory, wholesale, an API and scanner hardware, and its restaurant line adds tableside ordering, a kitchen display and reservations.

• Best for: a small business that already runs a few locations and wants stock visibility across them.
• Watch out for: no free plan or trial is listed, and it is closed source. See the Lightspeed listing.

Best open-source and self-hosted options

11. Odoo: best open-source suite for owners who want an ERP behind the till

Odoo is a set of open-source business apps in the browser, including point of sale, inventory, accounting, invoicing and eCommerce, which can run alone or together as an ERP. Odoo's shop POS page describes barcode scanners and scales, loyalty programs and gift cards, multi-store use and offline payments that sync when you reconnect.

You can host it yourself or pay for hosting, and one app is free. The listing marks the licence as Other, so read it on GitHub before you rely on it. See the Odoo listing.

• Best for: owners who want sales, stock and accounts in one system and can host it or pay for hosting.
• Watch out for: it is a large suite, and hosted plans are priced per user.

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

Open Source POS is a web-based point of sale written in PHP on MySQL or MariaDB. It covers stock, a sale register with transaction logging, quotations and invoicing, taxes including VAT and GST, cash-up, receipts, customer and supplier records, gift cards and reports, with multi-user permissions.

Its homepage cites MIT terms with a requirement to keep the footer signature in place. See the listing for recent GitHub activity.

• Best for: a technical owner running one small shop who wants to control the code and the data.
• Watch out for: the site does not describe card payments or offline use, and you maintain the server.

Which POS should your small business choose?

Shortlist two, check the live pricing section below for plan prices, and ask each vendor in writing how card payments are charged, what hardware you must buy and what works offline. If you only run a restaurant, the restaurant POS guide goes deeper, and there is a separate guide for food trucks.
