Odoo has an official methodology called Odoo Implementation Methodology (OIM) used by official Odoo partners to ensure successful, structured deployments.

Here’s an overview:

1. Analysis Phase

Understand business processes and gather requirements.

Interviews with key users (production, sales, accounting…).

Document current (As-Is) and desired (To-Be) processes.

Define project scope (modules, users, branches).

Timeframe: ~2 weeks

2. Design Phase

Translate requirements into system configurations.

Choose modules.

Design needed customizations (fields, reports, workflows).

Define interdepartmental connections and permissions.

Timeframe: ~2 weeks

3. Configuration Phase

Set up the system (Cloud or On-Premise).

Configure accounts, taxes, inventory, BoMs, users.

Import data (customers, vendors, products, opening balances).

Conduct initial process testing.

Timeframe: ~4 weeks

4. Testing Phase

Validate system functionality with real scenarios (sales, production, purchasing, accounting).

Involve actual users.

Fix issues or adjustments.

Timeframe: ~2 weeks

5. Training Phase

Train staff based on roles (cashier, accountant, production staff…).

Prepare simple internal user manuals.

Conduct live support sessions post-training.

Timeframe: ~2 weeks

6. Go-Live Phase

Transition from old system to Odoo.

Freeze legacy data.

Enter opening balances (stock, accounts...).

Activate system (gradually or all at once).

Daily monitoring by the implementation team.

Timeframe: ~1 week

7. Post-Go-Live Support

Ongoing support to resolve real-world issues.

Daily support tickets.

Periodic reviews.

Evaluation session after 30 days.

Timeframe: 1–4 weeks (depending on company size)
