How the Odoo Migration cost calculator calculates your range

The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.

  1. 1. Capture inputs

    The calculator records the visible project, volume, complexity and operating parameters selected on this page.

  2. 2. Add fixed components

    Fixed base modules and selected add-ons are added without mixing them with recurring charges.

  3. 3. Apply multipliers

    Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.

  4. 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. 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. 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.

Included

  • Inputs shown in the calculator
  • Calculator-specific base values and factors
  • Displayed one-off and recurring result components

Not included

  • Requirements not selected in the calculator
  • Unknown data migration and third-party licence costs
  • Taxes, legal advice and a binding delivery commitment

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.

FAQ

Odoo migration costs

Migration budget

What does an Odoo migration cost?

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.

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-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.

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)

Comparison: typical pricing models for software and IT projects
ModelWhen it fitsBudget & flexibilityTypical 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 & MaterialDiscovery, 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 packageOngoing 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.
