Best Odoo Apps: The 5 Everyone Needs (Plus 93,761 More)
Odoo ships with 100+ built-in apps. The marketplace adds 93,761 more. Most teams pick the same 5 to start. Here's how to choose the rest without drowning in options.
What You Get Built-In vs. Marketplace
Odoo's architecture is different from piecing together 10 SaaS tools. Everything shares one database. One user directory. One sync cycle.
Built-in apps, the ones Odoo includes, are free. CRM, Sales, Accounting, Inventory, Projects, Email Marketing, HR, Payroll, eCommerce, Helpdesk. All of them. No licensing per app.
Marketplace apps are third-party add-ons. Some are free. Many cost €50-€500/month depending on scope. Examples: custom dashboards, specialized connectors (WooCommerce, Amazon, Shopify), compliance modules (DATEV export for Germany, eInvoicing), and workflow automations.
Your pricing model is simple: €24.90/user/month (Odoo Standard) or €44.90/user/month (Odoo Custom with Studio access). All 100+ built-in apps included. Marketplace add-ons cost separately.
The core difference: built-in = always included. Marketplace = pay as you add.
The Core 5 Apps: What 7M+ Odoo Users Start With
1. CRM Lead tracking, sales pipeline, automation. Your first view into customer relationships. Every pipeline stage is customizable. Automation rules (auto-assign, auto-follow-up) reduce manual work.
2. Sales Quotations, orders, invoicing. Connected to CRM—when a lead becomes an opportunity, Sales takes over. No re-keying. Approval workflows built in.
3. Accounting/Invoicing Bank reconciliation, vendor bills, financial reports. Real-time P&L. Multi-currency support. Integrates with your bank (SEPA, SWIFT).
4. Inventory Real-time stock, multi-warehouse, automated reordering. Stock movements sync with Sales (order placed = stock reduced instantly). Barcode scanning included.
5. Project Management Tasks, timelines, Gantt charts, resource planning. Link projects to sales orders for time-to-bill tracking. Timesheets automate payroll.
These five handle 80% of what a growing team needs. Everything else—eCommerce, Manufacturing, Field Service, HR, Payroll—are add-ons you activate when you need them.
Free vs. Paid: What Costs Extra
Odoo Community Edition (100% open-source, self-hosted) is free. All 100+ built-in apps included. No seat limit.
Odoo Enterprise SaaS (hosted by Odoo) costs €24.90/user/month for Standard, €44.90/user/month for Custom. Includes infrastructure, daily backups, 24/7 monitoring, and automatic upgrades. This is all built-in apps.
Marketplace apps stack on top. Example costs from live listings:
- Webkul Multi-Vendor Marketplace: €296/month (one-time or annual)
- Specialized reporting dashboards: €50–€200/month
- WooCommerce/Amazon connectors: €50–€100/month
- Custom workflows and automations: quote-based
Ksolves (a major Odoo partner) offers apps like Dashboard Ninja with AI, Access Manager, and integration connectors—but prices are custom, not published. This signals enterprise/complex deals.
Budget tip: Start with the free built-in 5. Add marketplace apps only when a specific pain point appears. Most SMEs stay under €500/month total (€24.90/user/month + 2–3 marketplace add-ons).
App Store Quality Varies Widely
Reddit users have noted that 90–95% of apps in the Odoo store suffer from performance or quality issues. Stick to official Odoo apps, Odoo partner apps, and established third-party vendors (Ksolves, Webkul). Review ratings before installing anything new.
Beyond Core 5: Apps by Role
eCommerce teams add Website (online store builder), eCommerce (product catalog, cart), Shopper Loyalty, and connectors (Amazon, WooCommerce, Shopify). Multi-channel selling from one backend.
Manufacturing adds Manufacturing (production orders, bills of materials), MRP (inventory planning), and Shop Floor Control. Track raw materials → finished goods in real time.
Retail/Restaurant adds Point of Sale (POS terminals, payment processing), Barcode Scanner, and Loyalty programs.
Services/Consulting focuses on Projects, Timesheets, Contracts, and eSignature. Bill by the hour or by milestone.
HR-heavy teams layer Recruitment, Employees, Time Off, Payroll, Appraisals, and Timesheets. Payroll integrates with accounting—pay someone, their cost automatically hits the P&L.
Compliance-heavy regions (Germany, Spain, France) need localization apps: DATEV export (Germany), eInvoicing (Spain), CICA compliance (France). These are marketplace apps, not built-in.
