How many modules does Odoo actually have?

Odoo S.A. publishes 80+ official apps in the standard catalog. On top of that, the Odoo App Store has 40,000+ community modules — most are free, some paid (typically USD 200–800 one-time or USD 25–100/month). The 12 modules covered here are the most-deployed in mid-market implementations and cover the operational core of most businesses.

Do modules cost extra on the Enterprise plan?

No — Enterprise Standard and Custom plans include all 80+ official apps in the per-user license fee. There's no per-module pricing. Community edition includes a smaller subset of standard apps (CRM, Sales, Inventory, basic Accounting, HR, Project, …); modules like full Accounting, Manufacturing, Studio, and Field Service are Enterprise-only.

Which modules require the Enterprise edition?

On Community, you get the operational core (CRM, Sales, Inventory, Purchase, basic Accounting, HR, Project, Calendar, Contacts, eCommerce, Website, Marketing). Enterprise adds: full Accounting (with statutory reporting and bank sync), full Manufacturing (MRP II + Quality + PLM + Maintenance), Studio (no-code customization), Field Service, Subscriptions, Marketing Automation, Helpdesk, Sign, Documents, and others. Most partner-led mid-market deployments use Enterprise.

Can I use just one or two modules and ignore the rest?

Yes. Odoo's modular architecture means you can install only what you use. A common starting point is just Accounting + CRM for a 5-person business. The license cost is the same per user regardless of how many modules you install — you don't pay more by activating more modules. The constraint is configuration and training time, not licensing.

How does Odoo's app catalog compare to competitors?

Odoo's 80+ included apps is meaningfully broader than NetSuite (~30 modules at base), SAP B1 (~15 at base, more via add-ons), or Microsoft Dynamics BC (~20 at base). The trade-off is depth — NetSuite's Financials, SAP B1's Manufacturing, and Microsoft's Power Platform are individually deeper at the high end. For SMEs and mid-market, Odoo's breadth typically wins. For multi-billion-dollar enterprises, SAP S/4HANA or Oracle Fusion are usually a better fit.

Starter bundle for discrete or process manufacturers. Add Project for engineering-to-order, add CRM for B2B sales-led businesses.

Choosing what to install first

How do I decide which modules to install first?

Start with the modules where you have the biggest current pain or the most fragmented tooling. For most SMEs that's Accounting + CRM + Inventory (the "operational core"). For manufacturers it's Manufacturing + Inventory + Purchase. For services firms it's Project + Timesheets + Sales. Add modules in phases — don't try to install all 12 at once or you'll dilute training and adoption.
Can I add modules later without re-implementing?

Yes — that's the core promise of Odoo's modular architecture. New modules install into the same database, share the same master data (customers, products, employees), and integrate with the modules already in place. Adding a module 6 or 12 months post go-live is a focused configuration + training engagement, typically 2–6 weeks depending on the module.
Are there modules that don't play well together?

Almost none — Odoo's modules are designed by Odoo S.A. to integrate. The exceptions are usually when you install conflicting third-party apps from the Odoo App Store, or when you customize one module in a way that breaks another's expectations. Stick to official modules and your partner's recommended third-party apps and you won't hit conflicts.
