Month one: understand the operating model
The first stage maps how work moves through finance, sales, purchasing, inventory, field service, or manufacturing. The output should be a prioritised scope and a record of decisions, assumptions, dependencies, and exclusions.
Month two: configure and test the core flow
Configuration should follow the agreed process rather than reproduce every workaround. Teams review realistic scenarios, identify gaps, and decide which exceptions need a control, an integration, or a documented manual step.
Month three: prepare the people and data
Data cleansing, import templates, permissions, training, reporting, and cutover planning become the centre of gravity. A system can be configured correctly and still fail if the information and operating habits are not ready.
After go-live: stabilise before expanding
The first weeks are for resolving real usage issues, clarifying ownership, and measuring whether the new process is working. Additional modules and customisations should follow evidence, not the original wish list.
Common questions
How long does an Odoo implementation take?
It depends on scope, data quality and how many processes go live together. A focused core rollout is measured in months rather than years, and the scope and timeline should be agreed before work starts.
What happens in the first month?
The first stage maps how work moves through finance, sales, purchasing, inventory, field service or manufacturing, and produces a prioritised scope and a record of decisions and assumptions.
Why does data preparation matter so much?
A system can be configured correctly and still fail if the information going into it is poor. Data cleansing, import templates, permissions and cutover planning are delivery tasks, not admin.
When should we add more modules or customisation?
After go-live, once the first release is stable and the results are measured. Additional modules and customisation should follow evidence, not assumptions.
