Estimate the budget for your Odoo migration – from version upgrades to switching from legacy ERP or isolated tools, including data migration and training.
In brief
The investment frame is EUR 8,925 – 105,692 excl. VAT. Source system and module count change the scope inside this frame.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.
Concrete project profiles with assumptions and indicative budgets—useful for internal alignment alongside the calculator.
The upfront cost can be spread over 72 months. Terms are on the software financing page.
FAQ
The Odoo migration cost calculator gives EUR 8,925 – 105,692 excl.
VAT as its non-binding overall range. Source system, module count, data quality, version gap and customisation determine the concrete result.
Odoo versions receive updates for only about three years – older installations run without security patches and block server and Python upgrades.
The more versions you skip, the more expensive migrating custom modules becomes: a planned upgrade every 2–3 versions is the cheapest strategy.
Custom-module migration is included within EUR 8,925 – 105,692 excl.
VAT. It often pays to check whether standard features or community modules now cover the purpose, because every retired custom module also lowers future upgrade costs.
Discuss your Odoo migration
We audit your Odoo installation or legacy ERP and create a migration roadmap.
After the audit (modules, customisations, data quality) comes a test migration on a staging environment: data is transferred, custom modules adapted and core processes rehearsed.
Only after business sign-off does the production switch happen – usually over a weekend.
Master data, open items and documents can be transferred; for historical bookings, compliance requirements often make the combination of migrating open periods plus an audit-proof archive of the old system the most economical path.
We clarify this in the audit with your tax advisor.
A version upgrade with a few modules takes 6–10 weeks.
Switching from another ERP with data migration, custom modules and training takes 3–6 months – depending on module count and the business units' testing capacity.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
