Odoo is a modular enterprise resource planning (ERP) platform that bundles a large suite of business applications (CRM, Sales, Accounting, Inventory, Manufacturing, HR, eCommerce, Website, and more) into a single system. It is designed around a unified data model so departments can share workflows, reporting, and automations across apps.

Key Features

  • Large catalog of installable business apps (CRM, Sales, Accounting/Invoicing, Inventory/WMS, MRP, Purchase, HR, Project, Helpdesk, Website/eCommerce)
  • Single database and integrated workflows across modules (e.g., sales → invoicing → delivery → accounting)
  • Highly extensible server framework with custom modules, views, and business logic
  • Built-in access control and multi-company support for managing multiple entities
  • Web client with responsive UI, dashboarding, and reporting across business data
  • Internationalization support (multi-language) and localization packages for many countries

Use Cases

  • Replace disconnected tools with one ERP for sales, invoicing, purchasing, inventory, and accounting
  • Run end-to-end operations for SMBs (quotations, orders, stock, manufacturing, shipping)
  • Build custom line-of-business apps on top of Odoo’s modular framework

Limitations and Considerations

  • Some advanced features and apps are only available in Odoo Enterprise; the GitHub repo is the Community edition codebase
  • Upgrades between major versions can require migration work, especially with custom modules

Odoo is a broad, integrated business platform that can scale from small companies to complex multi-company setups. Its modular architecture allows starting with a few apps and expanding into a full ERP as needs grow.

Use Cases

  • Electronics/mechanical labs tracking parts, reels/bins, and BOMs for prototypes
  • Small manufacturers managing builds, stock consumption, and component traceability

InvenTree is well-suited for organizations that need accurate parts data, stock control, and BOM-driven production processes. Its web UI plus API and barcode-centric workflows make it practical for both day-to-day inventory operations and lightweight manufacturing execution.
