Which Odoo modules should I start with?

Never start with everything at once. Pick three modules that solve your biggest pain, go live with those, then expand. The most common starting point is Sales plus CRM, often with Inventory for trade and manufacturing, and optionally Accounting. Manufacturing, Project and HR belong in a later phase.

Odoo has 80+ modules. But never start with everything at once. Our rule: pick three modules that solve your biggest pain, go live with those, then expand.

The three most common starter modules

1. Sales + CRM

Almost every client starts here. Pipeline management, quotes, order confirmation, automatic follow-up. Immediate value, sales cycles get shorter and no one has to dig through a spreadsheet anymore.

2. Inventory

Essential for manufacturing and trading companies. Multi-warehouse, barcodes, automatic reordering, real-time stock value. Often connected to Sales.

3. Accounting

Optional in phase 1. Some clients keep their existing accounting (Exact, Twinfield) and connect it to Odoo. Others move to Odoo Accounting for maximum integration. See also: Can you connect Odoo to Exact or Twinfield?

What belongs in a Phase 2

  • Manufacturing (MRP), once production gets more complex, or when you need BOMs and work orders.
  • Project, for project-driven organisations (construction, services, IT).
  • HR + Timesheets, connect only once the basics run well.
  • eCommerce, Odoo’s webshop is capable, but if your shop already runs on Shopify or Magento, leave it there.

What a Phase 3 might be

  • Marketing Automation, automatic email campaigns, lead scoring.
  • Helpdesk, if you have a support team tracking tickets.
  • Subscription, for SaaS and subscription models.

The mistake we see often

Clients trying to implement everything at once. It takes too long, the team gets overloaded, and the go-live keeps slipping until everyone has had enough. Do it step by step.
