Free POS Software 2026: 7 Certified Tools Tested

Looking for free certified POS software? I tested 7 solutions for micro-businesses, retail shops and restaurants. Discover their limitations and recommendations.

TL;DR

Yes, genuinely free and certified POS software exists in 2026. For starting a small business, café or food truck, Square POS is unbeatable for its simplicity and complete ecosystem. For a retail shop needing solid inventory management without paying, Hiboutik is a gem, even if its interface is less modern. Just know that "free" usually means you pay through transaction fees on each sale. Always read the fine print before committing.

What Is a Certified POS System?

Before diving into the comparison, one critical point: the law. Since January 1, 2018, if you're VAT-registered and record customer payments in POS software, that software must be certified. This is the famous anti-VAT fraud law.

The goal is straightforward: prevent hidden revenue. Your software must guarantee data immutability, security, retention and archiving of transaction data. During an audit, you must be able to present a compliance certificate provided by the software publisher. There are two recognized certifications in France: NF525 and LNE (National Metrology and Testing Laboratory). Failing to comply exposes you to a €7,500 fine per non-compliant system, with 60 days to get into compliance.

I'm stressing this because I've seen too many founders—especially friends launching their first shop—tempted by "homemade" solutions on spreadsheets or obscure apps. It's a terrible idea. For a sole trader just starting out, administrative rigor is key to avoiding nasty surprises. Certification isn't optional—it's a legal requirement.

The Best Free POS Software in 2026

I've selected 7 solutions offering free plans. I analyzed them from the perspective of a freelancer or micro-business wanting to launch without blowing the budget. For each tool, I highlight strengths but especially limitations, because that's where hidden future costs hide.

Square POS

Best for: Freelancers, cafés, small shops, food trucks, and anyone wanting an ultra-simple solution to start.

Strengths: Square is the king of simplicity. Sign-up takes minutes and you can start accepting payments via smartphone almost immediately. Its ecosystem is the major strength: you can buy their sleek and efficient card reader, create a small online store, manage gift cards... Everything is integrated. The app is intuitive and works perfectly on tablet.

Limitations: The free plan excels at payment processing, but advanced features like multi-location inventory management or team management are paid. Main cost stays transaction fees: 1.65% on each card payment. Not the lowest on the market, but it's transparent.

Indicative pricing: Free software. 1.65% per card transaction. Hardware extra.

Hiboutik

Best for: Retail shops (clothing boutiques, gourmet groceries) needing solid inventory management from day one.

Strengths: Hiboutik is a pleasant surprise. It's French software offering an incredibly complete free version. You get inventory management, customer tracking (mini-CRM), products with variants, and of course NF525 certification. It runs on any device with a web browser, leaving you choice of hardware.

Limitations: Its user interface is... functional. You sense the tool is a few years old—less polished than Square. Customer support is reserved for paid subscribers, so free users rely on documentation. Integrations (e-commerce, accounting) are in paid plans.

Indicative pricing: Free software. Premium subscriptions from €29/month for more features.

SumUp Caisse

Best for: Restaurateurs and bar owners seeking a solution designed for their industry.

Strengths: SumUp acquired Tiller, a restaurant standard. Their offering is highly industry-specific: table management, kitchen order sending, bill splitting... The hardware ecosystem is well-designed, with mobile payment terminals that integrate seamlessly.

Limitations: Let's be clear: the truly free offering is a loss leader. It's very basic and forces you to use their hardware. To get genuinely useful restaurant features, you jump to paid plans that are quite expensive. It's more a free trial than a true long-term free solution.

Indicative pricing: "Caisse Lite" free offer with SumUp terminal purchase. Paid subscriptions for advanced features (from €39/month).

Zettle Go by PayPal

Best for: Mobile sellers, market stands, pop-up shops.

Strengths: Simplicity again. If you already have a PayPal account, it's even faster. The app is very lightweight and easy to master. Perfect for occasional or mobile transactions. Integration with PayPal's world is a bonus for fund management.

Limitations: The most basic in this selection. Inventory management is minimal, reports are simple. Don't expect it to manage a shop with hundreds of SKUs. It's a payment tool, not business management software.

Indicative pricing: Free software. 1.75% transaction fee per card payment.

Loyverse

Best for: Tiny operations (cafés, beauty salons) wanting loyalty features without paying.

Strengths: Loyverse stands out with its integrated, free loyalty program—rare for this. It also manages employees and works on any smartphone or tablet, reducing initial hardware costs. The interface is fairly pleasant.

Limitations: This is crucial: certification. Loyverse isn't NF525 or LNE certified. They provide an individual compliance certificate, but compliance responsibility falls on you. It's a risk I don't recommend taking. Use only if you're not VAT-registered—otherwise, avoid.

Indicative pricing: Free software. Paid add-ons for integrations or advanced management.

Stripe Terminal

Best for: Tech companies, businesses with strong web integration, and developers wanting custom solutions.

Strengths: Stripe is fundamentally a payment platform. Its strength is its incredibly powerful and flexible API. With Stripe Terminal, you can embed physical payments directly into your own app or workflow. It's the market's most customizable solution. If you're already managing customers via a custom CRM or tool like HubSpot, you can create a fully integrated payment experience.

Limitations: It's absolutely not an out-of-the-box solution. Don't expect to download an app and start selling in 5 minutes. You need either development skills or a partner app connecting to Stripe Terminal. It's a tool for building, not a finished product.

Indicative pricing: No monthly fees. Transaction fees (e.g., 1.5% + €0.25) + hardware cost. Tool page: /stripe.

Shopify POS

Best for: Any merchant with or planning a Shopify online store.

Strengths: Perfect synchronization. The omnichannel dream. A store sale updates your website stock in real-time, and vice-versa. Customer records are unified. Management happens from the same interface as your site. If your business is both physical and digital, it's far and away the most integrated and powerful solution.

Limitations: It's not truly free. The "POS Lite" feature is included in all Shopify plans, the cheapest at €36/month. Entry cost isn't zero. You're also locked into the Shopify ecosystem (payments, themes, apps).

Indicative pricing: Included in Shopify plans (from €36/month). Tool page: /shopify.

How to Choose Your Free POS Software?

Choosing a tool, especially "free" ones, commits you for a while. Migrating from one POS to another is real hassle. Here are the criteria I use advising clients.

1. Legal compliance: Non-negotiable. The tool must be NF525 or LNE certified, period. Ask for the certificate before even testing.
2. Real cost: Free software finances itself through transaction fees. Compare percentages, but also look at fixed per-transaction fees. Consider hardware cost: card reader, cash drawer, printer... Does the software mandate a brand or are you free?
3. Management features: Payment processing is just the visible part. Can the tool manage your inventory properly? Does it have CRM functions to track customers? For deeper dive, read our guide on the best CRM for SMBs and freelancers. Are activity reports exploitable to run your business?
4. Ecosystem and integrations: Your POS doesn't live alone. Does it integrate with your e-commerce solution like Wix or Webflow? Can you easily export data to your accounting software? Good integration with tools like Pennylane or Qonto saves hours monthly. This is crucial—see our Pennylane vs Qonto comparison.

Our Recommendation: Which Tool for Which Profile?

After all this testing, here's my verdict. There's no "best" tool in absolute terms, just the best for your needs.

For the freelancer or mobile seller (markets, pop-ups): Go with Square POS or Zettle Go. Your priority is simplicity, fast setup and reliable payment terminal. No need for complex features—just solid payment processing. Perfect for starting.

For the small retail shop or café launching: You can hesitate between Square POS for its disarming ease and Hiboutik for its free functional depth. My advice: if inventory management with variants matters, invest time mastering Hiboutik. If you prefer a more modern, all-in-one tool, Square feels better daily.

For the restaurateur: The free offer is a mirage in restaurants. Needs are too specific (floor plan, split bills, etc.). SumUp Caisse is a good entry point but budget for quickly moving to a paid plan. Don't start with a non-specialized tool or you'll regret it.

For the omnichannel merchant (physical shop + e-commerce): If your site runs on Shopify, the decision is made: take Shopify POS. Integration is a major competitive advantage. If you're on another platform, Square offers a good alternative with sync tools.

For the company with specific needs: If you have a developer team and want to embed physical payments in a custom app, Stripe Terminal is for you. It's a technology block, not finished software, but its power is unmatched. It's a bit like the difference between ERP and CRM—you need to know what you're building.

Remember that your POS choice directly impacts your invoicing and accounting. Think about it from the start.
