Migration · SAP → Odoo
Migrate from SAP Business One / SAP S/4HANA Cloud to Odoo
Mid-market manufacturers and distributors leave SAP B1 when the partner-channel support cost and per-seat license tax exceeds the value they're getting. Odoo handles the same operational scope, MRP, multi-warehouse, multi-entity, at 50-70% lower TCO. Typical migration: 16-24 weeks at $40K-$140K.
Why teams leave SAP
- SAP Business One license renewal hikes of 8-15% with no negotiation room
- SAP partner-channel fees and addon-tax on every customization
- Slow performance on multi-warehouse with 500K+ SKU master
- Crystal Reports licensing per seat with limited customization flexibility
- S/4HANA Cloud's two-system landscape adds complexity small teams can't absorb
- Difficulty hiring SAP B1 talent vs. relative ease of Odoo + Python developers
Octura's 6-phase migration playbook
- 01
1. Discovery + license audit
Week 1-3
Inventory SAP B1 module footprint (Production, Procurement, Inventory, Finance, etc.), customizations, add-ons (Beas, Boyum, Coresuite), and integrations. Calculate net license + maintenance cost being retired.
- 02
2. BOM + master-data profiling
Week 3-6
Export item master, BOM hierarchies, work centers, routings, customer/vendor master, COA. Profile data quality, SAP B1 deployments typically accumulate 10-20% duplicate items and BOM versions that need rationalization.
- 03
3. Mapping + script build
Week 5-12
Map SAP B1 records to Odoo. BOM hierarchies need careful flattening, SAP B1 supports phantom BOMs but in different syntax. Build transformation scripts including handling for User-Defined Fields (UDFs) and User-Defined Tables (UDTs).
- 04
4. Odoo configuration
Week 10-18
Configure Odoo MRP, Inventory, Accounting against the mapped model. Rebuild SAP B1 add-on functionality natively in Odoo where possible (Beas for shop floor → Odoo Work Center tablets, Boyum for usability → Odoo native UI).
- 05
5. Dry runs + UAT
Week 16-22
Two full dry runs into sandbox. Operations UAT focuses on shop floor flows, picking, BOM consumption. Finance UAT reconciles against SAP B1 trial balance for 3 historical periods.
- 06
6. Cutover + hypercare
Week 22-24
Single weekend cutover for single-plant deployments; phased cutover by plant for multi-plant. 60 days hypercare with shop-floor presence in first 2 weeks.
Data we migrate
- Chart of accounts and tax structures
- Customers, vendors, items, BOM, routings, work centers
- User-Defined Fields and User-Defined Tables (where Odoo equivalents exist)
- 3+ years of historical transactions
- Open SOs, POs, MOs, transfers, and inventory positions
- Crystal Reports → translated to Odoo Studio reports or QWeb PDFs
- Lot/serial traceability history (where present)
- Custom add-on functionality → rebuilt as native Odoo features or modules
Risks & how we mitigate
- BOM versioning and effective datingSAP B1 BOM revisions sometimes have effective-dating not in Odoo. We rebuild this as Odoo ECO (engineering change order) workflow with version history preserved.
- Add-on dependencies (Beas, Boyum, Coresuite)Each add-on inventoried during discovery with a documented Odoo replacement plan. Most add-on functionality is now native in Odoo 19; the rest gets built as custom modules.
- Crystal Reports libraryWe migrate top-20 most-used Crystal Reports to Odoo QWeb / Studio. The long tail gets retired during the project.
- S/4HANA Cloud two-system landscapeFor S/4HANA migrations specifically, the two-system landscape (Test + Production) maps to Odoo's branch-staging model (Odoo.sh). We maintain the same deployment discipline post-migration.
16-24 weeks for single-plant SAP B1 deployments. Multi-plant or heavy add-on dependencies extend to 28-36 weeks. S/4HANA Cloud migrations typically take 24-32 weeks given the larger functional surface.
$40K-$140K for migration + Odoo configuration. Multi-plant manufacturing $150K+. Odoo license cost typically drops 50-70% versus SAP B1, paying back the migration in 12-18 months across the customer base.

Book a migration consultSAP → Odoo migration FAQ
Can Odoo handle the same manufacturing complexity as SAP B1?
For mid-market manufacturers (50-500 employees, 1-4 plants), yes. Odoo MRP supports multi-level BOMs, routings, work centers, quality, maintenance, and subcontracting on one database. Where SAP B1 still wins: complex APS scheduling (advanced planning) at very tight constraints, and process-industry recipe management at refinery scale.
What happens to our SAP B1 partner contract?
We coordinate the transition with your SAP partner. Standard practice: 90 days notice to the SAP partner, freeze their work on new features, finalize support handover documentation, then transition fully to Octura at migration cutover.
How do you handle Crystal Reports we depend on?
We migrate the top-20 most-used Crystal Reports to Odoo QWeb (for PDFs) or Studio reports (for ad-hoc) before cutover. The long tail of reports nobody actually uses gets retired during the migration discovery phase.
Can we keep our SAP B1 add-ons during transition?
Only during the parallel-run period (typically 4-6 weeks). At cutover, all SAP B1 add-ons stop being authoritative; Odoo equivalents take over. We've never had to keep SAP B1 add-ons running post-cutover.
What's the typical TCO comparison?
A 100-user SAP B1 deployment with 2 plants and 4 add-ons runs $180K-$280K/year all-in. Equivalent Odoo deployment (Custom tier + Octura hosting + support) runs $80K-$140K/year. Migration cost pays back in 12-18 months.
