Why ERP projects often fail

70% of ERP projects exceed their initial budget. The cause is rarely technical — it's almost always a methodology problem. Poorly scoped requirements, rushed data migration, untrained users: the failure points are well known and avoidable.

A well-run Odoo integration follows five precise steps. Here is the method Advences applies to every project.

Step 1 — Requirements scoping (2 to 4 weeks)

Before opening Odoo, we map your current processes: purchasing, sales, production, accounting, HR. The goal is to identify what stays standard and what requires custom development.

The deliverable: a functional specification and a firm quote. No budget surprises mid-project.

• Business workshops with your operational teams
• Identification of third-party integrations (e-commerce, EDI, banking APIs)
• Module prioritisation (phase 1 vs phase 2)
• Data migration plan validation

Step 2 — Configuration and custom development (4 to 8 weeks)

Odoo covers 80% of needs out of the box. The remaining 20% is what makes the difference between a generic tool and an ERP tailored to your business. This step combines module configuration and bespoke development.

• Configuration of accounting rules, taxes, journals
• Sales, purchasing and inventory flow setup
• Custom development (modules, reports, connectors)
• Unit testing and functional acceptance testing

Step 3 — Data migration (2 to 3 weeks)

Data migration is the most underestimated part of an Odoo project. Contacts, products, invoicing history, stock levels — each dataset requires precise mapping and rigorous validation.

Advences delivers a full migration report: match rate, missing data, anomalies detected and corrected before go-live.

Step 4 — User training (1 to 2 weeks)

An unadopted ERP is a failed ERP. Training isn't a box to tick at the end of the project — it's the condition for ROI.

• Role-based training sessions (sales, finance, logistics, management)
• Hands-on sessions using your real data
• Personalised user documentation
• Super-users identified and trained for internal support

Step 5 — Go-live and post-launch support (4 weeks)

Go-live isn't the end of the project — it's the start of real operations. The first weeks in production always reveal adjustments: untested flows, edge cases, user questions.

Advences provides dedicated support for 4 weeks after go-live: functional helpline, rapid fixes, configuration adjustments.
