Why in 2026 and 2027 migrating from SAP to Odoo is no longer a brave choice, but a strategic one
If you run an Italian SME, you probably know this situation well: your SAP system works, but every customization costs thousands of euros, every update takes weeks of consulting, and the annual fee keeps growing. Meanwhile, the market demands that you be more agile, faster, more digital.
In 2026 the scenario has changed. Mainstream maintenance for SAP ERP 6.0 (ECC) ends on 31 December 2027 for installations on Enhancement Packages 6, 7 and 8; after that date SAP offers paid extended maintenance until 2030 (source: SAP) and pushes customers toward S/4HANA, which is a migration project in its own right. It is in this context that migrating from SAP to Odoo establishes itself as the concrete alternative — no longer just for startups, but for structured companies with complex processes.
In this guide we analyze the costs, timelines, risks and benefits of this transition.
SAP vs Odoo in 2026: the comparison SMEs need to know
License costs and 5-year TCO
The first factor that drives Italian SMEs to consider an alternative to SAP is the total cost of ownership (TCO). The licensing models are very different:
- SAP Business One: perpetual license with an annual maintenance fee, or subscription, plus the partner's costs for implementation and customizations.
- SAP S/4HANA Cloud: subscription, usually with demanding implementation projects.
- Odoo Enterprise: per-user subscription with public prices (Odoo pricing); the Community edition is free.
The comparison has to be made on the 5-year TCO, adding up licenses, implementation, maintenance, customizations and version upgrades: that is where the differences become clear. During the assessment we calculate it on your real figures.
Flexibility and customization
Odoo is an open source ERP with thousands of modules available between the official App Store and the OCA community. This means that every business process — from Italian accounting with electronic invoicing to warehouse management with lot traceability — can be configured or extended without depending on a single vendor.
Customizations also follow a different logic: in SAP they go through ABAP development, in Odoo through Python modules kept separate from the standard code, which remain upgradable from one version to the next.
Italian regulatory compliance
A frequent doubt: "Does Odoo handle Italian tax regulations?". The answer is yes. Recent Odoo versions, from 18 (released in October 2024) onwards, natively include:
- Electronic invoicing compliant with the Interchange System (SdI)
- Bank receipts (Ri.Ba.) and transport documents (DDT)
- Withholding tax management
- Italian chart of accounts, general journal and balance sheet
For VAT registers and periodic VAT settlement, the open source modules of the Italian community are added (OCA l10n-italy), also available for Odoo 18.
Once the "why" of the migration is clear, the "how" remains — starting with which edition of Odoo to choose, Community or Enterprise, a decision that affects costs for years.
When it makes sense to migrate from SAP to Odoo (and when it doesn't)
Migration is recommended if:
- The overall cost of SAP grows faster than the value it delivers — licenses, maintenance and partner work erode margins rather than creating them.
- The company is an SME with standard or moderately customized processes — the context where Odoo offers the best features/cost ratio.
- Processes require frequent customizations — Odoo's open architecture makes every change faster and less expensive.
- The company is evaluating the move to S/4HANA — if you have to face a migration anyway, evaluating Odoo as the destination is due diligence.
- You need integration with e-commerce, CRM or digital tools — Odoo natively integrates these modules, eliminating costly middleware.
Migration may not be advisable if:
- The company has hundreds of ERP users and highly verticalized SAP processes (e.g. SAP PP for complex manufacturing with integrated MES).
- There are deep integrations with specific SAP solutions (SuccessFactors, Ariba) that are hard to replace.
- The sector requires specific certifications tied to the use of SAP (rare, but present in some regulated fields).
How a SAP → Odoo migration works: the 6 phases
A well-planned SAP to Odoo migration follows a structured process. Here is how we operate at Globalist Technology, based on direct experience with Italian SMEs:
Phase 1: Assessment and process mapping (2-3 weeks)
We analyze the existing SAP installation: active modules, ABAP customizations, Z reports, integrations with external systems, data volumes. We map each process onto Odoo to identify functional gaps and define the migration strategy.
Output: gap analysis document with cost estimate and detailed timeline.
Phase 2: Designing the Odoo solution (2-4 weeks)
We define the target Odoo architecture: standard modules, specific configurations, any custom developments. In this phase the critical choices are made: cloud or on-premise hosting, data migration strategy (big bang vs. parallel), training plan.
Phase 3: Data migration (3-6 weeks)
The most delicate phase. The data from SAP — customer and supplier master data, chart of accounts, price lists, bills of materials, order history — is extracted, cleaned and transformed into the Odoo format. We use custom ETL scripts and Odoo's native import framework.
The migration is also the opportunity to clean up obsolete, duplicated or inconsistent master data, improving overall data quality.
Phase 4: Configuration and development (4-8 weeks)
We configure Odoo according to the specifications defined in phase 2. Custom developments follow Odoo best practices (separate modules, automated tests, technical documentation) to ensure future upgradability.
Phase 5: Testing and UAT (2-4 weeks)
Functional tests on every process, end-to-end integration tests and User Acceptance Testing with key users. Every anomaly is tracked and resolved before go-live.
Phase 6: Go-live and post-migration support (1 week + 3 months)
Go-live typically happens over the weekend to minimize operational impact. It is followed by 3 months of intensive support with a guaranteed SLA to quickly resolve any critical issue.
Typical total timeline: 3-6 months, depending on the scope.
The 5 mistakes to avoid in a SAP to Odoo migration
Experience has taught us that problems in migrations almost always arise from planning, not from technology. Here are the most common mistakes:
- Replicating SAP in Odoo: the worst possible mistake. Odoo has its own logic and its own strengths. Trying to reproduce SAP flows exactly means losing Odoo's advantages and multiplying custom development costs. You have to rethink processes, not translate them.
- Underestimating data migration: "it's just data to move" is a phrase we have heard too often. It is often the item that takes more time and budget than expected: plan it carefully.
- Ignoring user training: an ERP is only as effective as the people who use it. Plan at least 2-3 days of training per user, with role-specific sessions.
- Choosing the wrong partner: a partner who knows Odoo but not SAP won't be able to manage the migration effectively. You need expertise in both systems and, ideally, specific experience in your sector.
- Not planning the transition period: always plan a parallel-run period of at least 1 month for critical processes (accounting, inventory). It costs more in terms of effort, but it eliminates the risk of operational disruptions.
Odoo as a growth platform: beyond the traditional ERP
A strategic advantage of Odoo that often emerges after the migration is its nature as an integrated platform. While SAP requires separate (and costly) solutions for CRM, e-commerce, HR, marketing automation, Odoo offers everything in a single ecosystem:
- CRM and sales pipeline integrated with accounting and inventory
- B2B and B2C e-commerce with automatic synchronization of catalog, prices and availability
- Marketing automation with email marketing, segmentation and lead tracking
- Document management with digital signature and approval workflows
- Business Intelligence with customizable dashboards and real-time reports
- IoT and Industry 4.0: connection with sensors and machinery for production monitoring, predictive maintenance and automated quality control
For Italian SMEs facing digital transformation, Odoo represents a platform that can grow with the company without requiring costly integrations or system changes.
The role of open source ERP in the future of SMEs
Interest in open source ERP is driven by three factors:
- Data sovereignty: with an open source ERP like Odoo, the company has full control of the code and the data. It is not bound by a vendor lock-in that can impose price increases or unilateral platform changes.
- Speed of innovation: Odoo releases a major version every year with hundreds of new features. The SAP innovation cycle is slower and often reserved for S/4HANA customers.
- Community and ecosystem: with over 13 million users (Odoo figure, November 2024) and a global community of developers, Odoo benefits from an ecosystem that accelerates innovation and ensures long-term support.
How much does a SAP to Odoo migration really cost?
Transparency on costs is essential. Here is a realistic estimate for an Italian SME with 20-50 users:
- Assessment and gap analysis: 1,500 - 3,000 €
- Implementation and configuration: 10,000 - 30,000 €
- Data migration: 5,000 - 10,000 €
- Custom developments: 5,000 - 15,000 € (variable depending on complexity)
- Training: 1,500 - 4,000 €
- Post go-live support (3 months): 500 - 1,000 €
Total range: 23,500 - 63,000 €, with an average of 30,000-38,000 € for a manufacturing company with 30 users and medium complexity.
Every migration is different: these figures are averages built up over years of experience and are meant to give an order of magnitude. A precise estimate is only possible after analyzing your SAP installation and your processes.
