Context: Two different giants
Odoo = open-source, modular, flexible mid-market player, 7M+ global users. SAP Business One = closed-source, stable ERP for SMBs with 10-500 employees, 70,000+ global clients, a leader for manufacturers with international standards. The choice depends on 9 key factors.
Scoring across 9 dimensions (1-10)
1. Total Cost of Ownership (5 years) — Odoo 9, SAP B1 5. Odoo Community = free; Enterprise ~€15-20/user. SAP B1 = license €25-45k + implementation €40-120k + B1i integration €8-15k.
2. Flexibility & Customisation — Odoo 9, SAP B1 6. Odoo allows Python/XML modifications directly in the code. SAP B1 = more rigid SDK, requires a certified partner.
3. Manufacturing & MRP — Odoo 7, SAP B1 8. Odoo MRP is solid for discrete manufacturing, but SAP B1 + Boyum Add-on = more mature for complex processes + advanced planning.
4. Retail & Multi-store POS — Odoo 8, SAP B1 6. Odoo features native POS + eCommerce + offline sync. SAP B1 requires LS Retail or specialized local partners for advanced POS.
5. E-commerce & Marketplaces — Odoo 7, SAP B1 5. Odoo has a native website builder + eCommerce. SAP B1 = third-party connector or custom build. Both require a Smart Layer for serious marketplace sync (Amazon, eMAG, etc.).
6. Localisation & Tax Authority Compliance — Odoo 8, SAP B1 7. Odoo Accounting RO = e-Factura, D300, D394, VAT split, implemented by the community + RO partners. SAP B1 = certified RO localization, but updates for ANAF (the Romanian tax authority) can be slower (dependent on SAP + local partner).
7. Ecosystem & Integrations — Odoo 8, SAP B1 7. Odoo Apps Store = 30,000+ modules. SAP B1 = smaller but enterprise-grade marketplace (EDI, banking, BI).
8. Support & Stability — Odoo 6, SAP B1 9. SAP = global SLA, 99.9% uptime, exhaustive documentation. Odoo = partner-dependent; Community = no official support.
9. Upgrades & Longevity — Odoo 6, SAP B1 9. SAP B1 = 10+ year guaranteed roadmap, predictable annual upgrades. Odoo = 12-month release cycle, Community migration = hidden costs.
Decision Tree
Choose Odoo if: you have 20-150 employees, want flexibility, have internal IT resources or a good partner, want native e-commerce, have a limited budget (Community) or are mid-market (Enterprise), and perform discrete manufacturing or FMCG distribution.
Choose SAP B1 if: you have 50-300 employees, perform complex or multi-factory manufacturing, need guaranteed stability, plan international expansion, have an €80-200k ERP budget, and already have an SAP infrastructure.
Neither is sufficient alone if: you sell to major retailers (Carrefour, Kaufland, Lidl, Metro) → both require mature native EDI. Odoo does not generate native EDIFACT; SAP B1 requires B1i + custom mapping per retailer. See EDIconnect Azuvio.
Conclusion
Odoo wins on cost and flexibility. SAP B1 wins on stability and complex manufacturing. For mid-market companies selling omnichannel, both require a Smart Layer for OMS, EDI, AI, and compliance. See also Odoo vs Dynamics 365 BC.
