FAQ
Odoo migration costs
Migration budget
What does an Odoo migration cost?
Upgrading an older Odoo version with a few modules starts at around EUR 15,000–25,000 excl. VAT. Switching from another ERP or from isolated tools to Odoo runs EUR 25,000–70,000 depending on module count and customisation. The calculator narrows the range by source system, modules and customisation level.
Why are old Odoo versions a cost risk?
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.
What does migrating custom modules cost?
Custom modules must be adapted to the new Odoo API at every version jump – included in the calculator from about EUR 9,500. It often pays to check whether standard features or community modules now cover the purpose: 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.
Process & technology
How does an Odoo migration run?
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.
Can accounting data and documents be fully migrated?
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.
How long does an Odoo migration take?
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.
Typical pricing models (overview)
| 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. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
