Odoo SaaS vs guided ERP project: two very different ways to implement

Not all ways of using Odoo are the same.

This article explains the real differences between self-implementing Odoo as SaaS and undertaking an ERP project with guidance.

Editorial note

Choosing the implementation model is as important as choosing the software.

SaaS Model

What is Odoo SaaS

Odoo SaaS is the model in which the infrastructure and technical operation are managed directly by Odoo. You can contract access to the software from their website.

This model includes:

  • Immediate access to the platform
  • Hosting managed by Odoo S.A.
  • Automatic updates
  • Basic support included

The company activates modules, configures options, and starts using the system on its own.

Self-service

The SaaS model is designed so that the company configures and manages Odoo without intermediaries, or with occasional help from Odoo directly.

Reality

What self-implementation entails

Self-implementing Odoo means that the company takes on:

Defining its own processes in the system
Configuring modules and fields
Training users internally
Resolving doubts and problems on its own

A change project

An ERP project is not just installing software. It is redesigning how the company manages its operations.

Guided project

What is an ERP project (with guidance)

An ERP project is an implementation process that includes:

  • 1Analysis of the company's current operations
  • 2Definition of processes in the system
  • 3Assisted configuration of modules and workflows
  • 4Data migration or loading
  • 5Tailored training for each team
  • 6Guidance during the go-live phase

The goal is for the ERP to reflect how the company actually works.

When each model works

SaaS

Can work when...

  • Operations are very simple and standard
  • Basic functionalities are sufficient
  • You have a clear scope
  • You are willing to learn incrementally
  • Cost is the absolute priority
ERP Project

Is necessary when...

  • You want to redefine and improve operations
  • You are open to functional advice
  • There are specific business rules
  • There is a committed go-live date
  • The ERP will be critical for the business
Hidden costs

The hidden costs of SaaS without a project

SaaS seems more economical because it does not include services. But that does not mean the work disappears.

It simply becomes the company's responsibility:

Internal time

Hours the team spends learning, testing, configuring

Process errors

Incorrect configurations that affect operations

Rework

Redoing what was misconfigured once detected

Lost opportunities

Not using functionalities that would have added value

The real cost

The total cost is not what you pay per month. It is what you pay + what you invest + what you lose.

And that, in a SaaS without guidance, is usually much more than expected.

Decision

Checklist for deciding

Answer honestly before choosing the model:

Does anyone in my company know how to define ERP processes?

Do we have time to learn the system on our own?

Can we assume the risk of configuration errors?

Are our processes really that simple?

What happens if something fails and we have no one to turn to?

Practical rule:

  • If you hesitate on more than 2 questions, consider a guided project
  • If your answer is “no” to most, SaaS will end up being expensive

Total freedom

Community allows you to choose the implementation model without depending on licenses or on Odoo S.A.'s infrastructure.

Context

What role does Community play in all this

Odoo Community is the free and open version of Odoo. It is not tied to the official SaaS model from Odoo S.A.

This means that:

  • You can use it on any infrastructure
  • You can hire guidance without paying a license
  • You can combine OCA modules with custom developments
  • Project control remains with the company

Choosing how to implement is as important as choosing the software. Do not let the initial price be your only criterion.

A well-implemented ERP is a tool that grows with you. A poorly implemented one is a problem that scales.
