If you’ve ever wondered, “What are the modules in Odoo?”, the answer is straightforward: they are individual applications within the Odoo ecosystem designed to handle specific business functions. For example, there’s a module for Odoo Inventory, another for Sales, HR, Accounting, and so on.
These modules can be installed individually or combined, offering a modular approach to ERP. Businesses can start small with free modules such as CRM or invoicing, then expand with premium add-ons like advanced HR or multi-warehouse inventory management.

A common question is, “Do big companies use Odoo?” The answer is yes. While Odoo is popular among SMEs, many large enterprises also leverage it.

For UK businesses, this proves that Odoo can handle both small and large-scale operations effectively.
Another frequent question: “Are Odoo modules free?” Some are, while others are paid. The Odoo Community Edition offers free modules like CRM, Sales, and basic Inventory.

Odoo pricing generally starts at £20 per user/month, with additional costs for hosting and third-party modules available on the Odoo Apps marketplace.
Choosing the right modules is only half the journey. Implementation, customisation, and ongoing support matter just as much. Working with an Odoo official partner ensures you receive certified expertise, UK-specific customisations, and long-term support to make the most of your investment.
Odoo Modules are a powerful way for UK businesses to simplify operations, integrate processes, and drive growth. From Odoo Inventory for manufacturers to HR and marketing automation for service-based companies, the right selection of modules can transform day-to-day operations. While some modules are free, advanced capabilities come at a cost under Odoo pricing plans. Importantly, partnering with an Odoo official partner ensures smoother implementation and customisation tailored to UK business needs.
In summary, whether you are in retail, manufacturing, or services, adopting the right Odoo Modules could be the competitive edge your business needs in 2025 and beyond.
