Prices gathered on 29 September 2026 from the vendors' official pages, excl. VAT where the vendor says so (most often billed annually) — to be confirmed on each vendor's website. Excel is not in the table: free and familiar, but with no mobile, no traceability and no reliable multi-user support (see our inventory management in Excel guide).

The 9 tools in detail
GSE-Web — French SaaS dedicated to inventory management for logistics SMBs (5 to 50 people). Native mobile app with barcode scanning, offline mode, location management, batches, expiry dates, stock movement notes and picking. Support provided directly by the maker.
Strengths Field features from €199/year excl. VAT: mobile + offline, batch traceability, human support in French.
Limitations No built-in accounting (export to your accountant), no payroll and no CRM; less advanced e-commerce catalog than a general-purpose ERP.
Ideal for: Industrial and logistics SMBs, local authorities and vocational schools that want to master field stock without a gas-factory setup.

Odoo — very comprehensive modular ERP, available as an open-source Community edition or a paid Enterprise edition (stock, sales, purchasing, accounting, CRM…). Powerful and extensible, with a large ecosystem of apps and integrators.
Strengths Enormous functional coverage, rich Inventory module, active community.
Limitations Implementation is not included in the subscription: Odoo sells it as packs of hours (Success Packs); according to the vendor, companies with more than 50 employees generally work with a partner.
Ideal for: SMBs that want a unified ERP and are willing to invest time in it.

Sage — historical reference for management and accounting in France. Inventory management exists as a module within a finance/accounting-oriented suite.
Strengths Robust accounting, compliance, a network of resellers and accountants familiar with the tool.
Limitations Sage 50 and Sage 100: limited mobility and field scanning (the mobile software offered as an add-on to Sage 100, Sage Sales Management, is aimed at travelling sales staff); accounting rather than logistics logic.
Ideal for: SMBs whose center of gravity is accounting and commercial management.

Zoho Inventory — inventory management SaaS geared toward e-commerce and multichannel, integrated into the Zoho suite (Books, CRM, etc.).
Strengths E-commerce integrations (including Shopify), mobile app with barcode scanning, free plan.

Ideal for: e-merchants and SMBs selling across several online channels.
See Zoho Inventory →
Sellsy — French CRM + invoicing + commercial management suite (TeamSystem group), with an optional Stock module.
Strengths Good sales/invoicing/follow-up coupling, polished interface, French-language support.
Limitations Stock is an optional module; batches, expiry dates, bin locations and scanning rely on the partner app Stockpit, billed separately.
Ideal for: commercial SMBs and service providers that mainly drive sales and invoicing.
See Sellsy →
Henrri — free French invoicing software (Rivalis group), with simple item management.
Strengths Free, immediate onboarding, e-invoices through an approved partner platform, ideal for getting started.
Limitations No inventory management and no native mobile app: Henrri is invoicing software.
Ideal for: micro-businesses and freelancers whose need is invoicing, not logistics.
See Henrri →
Monstock — French WMS and supply chain management solution, with an advanced mobile app and scanning.
Strengths Advanced warehouse management, strong mobility, suited to complex, multi-site flows.

Cegid — French maker of management suites (retail, ERP, accounting, payroll). Inventory management is part of a broad, structured offering.
Strengths Complete and proven solution, strong retail presence, compliance and longevity.
Limitations Cegid XRP and Cegid Retail ERPs on quote; the built-in WMS is part of Cegid XRP Ultimate, aimed at mid-caps and large companies.
Ideal for: larger SMBs and networks, notably in retail.

Before comparing prices, clarify your real need. Six criteria settle most choices:
- The core need — field stock, accounting, sales or e-commerce? A tool that is excellent outside its domain remains a bad choice.
- Mobility — do your teams count and scan from a smartphone? This is the point that separates logistics software from desktop software.
- Traceability — batches, expiry dates, serial numbers: essential in food, pharma or aerospace, secondary elsewhere.
- Real total cost — beyond the displayed price: modules, additional users, integrator, maintenance.
- Deployment speed — a few days for a dedicated tool, several weeks to months for an ERP.
- French-language support — a contact who understands your business is worth more than a knowledge base in English.
