Odoo is an all-in-one business management software — an ERP (Enterprise Resource Planning) platform that replaces dozens of separate tools with a single, integrated system. From accounting and inventory to CRM and HR, Odoo connects every department in your company through one database.
What Exactly Is Odoo?
Odoo (formerly known as OpenERP) is an open-source ERP software developed by the Belgian company Odoo S.A. It was founded in 2005 and has grown into one of the most widely used ERP platforms globally, with over 12 million users across 150+ countries.
The name "Odoo" reflects the platform's modular, open nature — you start with the modules you need and expand as your business grows. Unlike monolithic ERP systems like SAP ECC, Odoo lets you activate only the applications relevant to your business and pay accordingly.
In the DACH region (Germany, Austria, Switzerland), Odoo has seen rapid adoption among SMEs and mid-market companies as a cost-effective alternative to SAP Business One or Microsoft Business Central.
What Is Odoo Used For?
Odoo covers virtually every business function through its modular app structure. Here are the most commonly used modules:
| Module | What It Does | Who Uses It |
|---|---|---|
| Accounting & Finance | Invoicing, bookkeeping, bank reconciliation, tax reporting | Finance teams, accountants |
| Inventory | Stock management, warehousing, barcode scanning, lots & serials | Warehouse managers, logistics |
| Sales & CRM | Sales pipeline, quotations, customer management, forecasting | Sales teams |
| Manufacturing | Bills of materials, production orders, work centers, quality control | Production managers |
| Purchase | Purchase orders, vendor management, RFQ, landed costs | Procurement teams |
| Human Resources | Employee records, attendance, leave management, payroll | HR departments |
| eCommerce | Online shop integrated with inventory and accounting | Online retailers |
| Project | Task management, timesheets, Gantt charts, billing by project | Service companies |
Odoo Community vs. Enterprise
Odoo comes in two editions:
- Community Edition — Free and open-source. Great for small businesses with technical resources. Missing some key features like full accounting, eCommerce, and advanced manufacturing.
- Enterprise Edition — Paid subscription. Includes the full app library, studio (no-code customization), Odoo.sh hosting, mobile apps, and official support from Odoo S.A.
Most growing businesses in the DACH region opt for Enterprise once they need DATEV integration, multi-company setups, or advanced reporting. The subscription pricing is per user per month — see our full Odoo pricing guide for details.

Talk to an Expert →How Does Odoo Work?
Odoo is built on a modular architecture. All modules share a single database, which means data flows seamlessly between departments — no manual exports or duplicate data entry.
For example: when a salesperson confirms a quotation in the CRM, it automatically creates a delivery order in Inventory, triggers a purchase order if stock is low, and generates an invoice in Accounting — all without any manual intervention.
Technically, Odoo runs on:
- Backend: Python (server), PostgreSQL (database)
- Frontend: OWL framework (JavaScript), custom web client
- Deployment: On-premise, Odoo.sh (cloud), or third-party hosting
Who Uses Odoo?
Odoo's sweet spot is small to mid-sized companies (10–500 employees), but it scales to larger enterprises too. Common sectors using Odoo in the DACH region include:
- Manufacturing and industry (Mittelstand)
- Wholesale and distribution
- Retail and eCommerce
- Professional services and consulting
- Construction and project-based businesses

Is Odoo Right for Your Business?
Odoo is a strong fit if:
- You want to replace multiple disconnected tools (Excel, separate accounting software, CRM, etc.) with one system
- Your business is growing and you need a scalable platform
- You want customization flexibility without paying for SAP-level implementation costs
- You're open to cloud or hybrid deployment in the EU
Odoo may not be the best fit if you need industry-specific certifications (e.g., FDA compliance for pharma), already have heavy SAP investments, or require offline-first functionality in manufacturing.
