Image from Openverse (CC BY)Since the 2018 anti-fraud VAT law in France, any company making cash sales to individuals must use a certified inalterable POS software. Free POS software has become a natural response for small businesses, micro-entrepreneurs and new retailers wanting to comply with legal requirements without engaging initial investment.
This comparison analyzes the seven most relevant solutions for retail, restaurants and itinerant activities in 2026.
Why a dedicated checkout system
Maintaining a manual cash register or using a spreadsheet exposes you to several legal and operational risks in 2026: NF525 non-compliance, non-standardized receipt, fragile traceability in case of tax audit. A retailer audited without a certified system risks up to 7,500 € fine per establishment and per non-compliant register.
A modern POS platform brings three concrete operational benefits:
- Automated regulatory compliance: compliant receipt with mandatory mentions, sealed inalterable archiving, event journal, daily Z report.
- Real-time commercial steering: revenue per day, per product, per employee, inventory tracking and reorder alerts.
- Ecosystem integration: export to accounting, synchronization with payment terminal, link with dedicated inventory management software for multi-reference brands.
The benefit also extends to invoicing: a well-integrated POS system can automatically generate compliant invoices for occasional B2B sales, without double entry.

Hiboutik: the all-in-one free cloud POS
Hiboutik is in 2026 the most complete free POS software solution available in France. Published by a French company since 2014, its economic model relies on optional premium features (from 14 € per month) while the core application remains totally free, without advertising or arbitrary limitation.
Free features include:
- Unlimited number of products, services and categories.
- Unlimited number of terminals and users.
- Inventory management with reorder alerts.
- Customer file with purchase history and loyalty by points.
- Multi-payment modes (cash, card, check, restaurant ticket, mixed).
- Daily, monthly and annual Z report.
- Certified NF525 compliance.
- Web app compatible with tablet, smartphone and PC.
The Premium version adds multi-store management, native mobile app, and certain advanced accounting integrations. For 90% of retailers and small businesses, the free version covers all common needs.
Sumup and Zettle: free POS software coupled with terminal
Sumup and Zettle by PayPal have popularized a particular model: POS software is fully free, funded by commissions on card payments processed via their physical terminal. This approach is particularly suited to itinerant retail, home services, markets and occasional activities.
Sumup POS offers:
- Mobile and tablet app for iOS and Android.
- Unlimited product catalog with photos.
- Customer management and loyalty program.
- Issuance of B2B invoices with legal mentions.
- Analytical dashboard.
- Certified NF525 compliance.
These solutions are particularly relevant for self-employed profiles in sales activity or for small retailers with low monthly volume wanting to avoid any fixed subscription.
Cashpad and sector-specific solutions
Cashpad has built its reputation on the restaurant market, with a free version limited to one terminal and a Premium version (from 49 € per month). For retailers exceeding the small business framework, Lightspeed Retail or Tactill remain the paid references. At this engagement level, integration with a system for piloting multi-site deployment projects or an accounting platform adapted to growing small businesses becomes a coherence criterion.
How to choose your checkout software
Five criteria orient the decision:
1. Activity type (sedentary retail, itinerant, restaurant, services) Sedentary retail with inventory: Hiboutik. Itinerant activity: Sumup or Zettle. Restaurant: Cashpad or L’Addition.
2. Transaction volume and number of terminals Single terminal: free Hiboutik or Cashpad version. Multiple terminals: Premium Hiboutik or Tactill. Multi-store: Lightspeed Retail.
3. Accepted payment modes If retail accepts mainly cash and check: pure POS software (Hiboutik) suffices. If majority of payments are by card: a coupled Sumup or Zettle system can be more economical.
4. Legal compliance and sector Imperatively verify NF525 certification in the version used.
5. Integration with accounting and management Compliant accounting export is now standard on all cited solutions. Direct synchronization with accounting software is rather present in Premium versions.
