What Our Odoo Developers in the UK Build
Standard Odoo covers a great deal, but most growing businesses eventually need something that is not in the box. Our team works on the full Odoo stack, from Python business logic and PostgreSQL data models to the OWL front-end framework used in recent Odoo versions. Typical work includes:
- Custom modules: new apps or extensions for processes Odoo does not cover, such as hire and rental workflows, job costing rules, commission calculations or industry-specific approvals.
- Integrations and APIs: connections between Odoo and e-commerce platforms, marketplaces, payment providers, payroll software, carriers and in-house systems using Odoo’s external API, webhooks or scheduled data exchanges.
- Reports and documents: branded invoices, delivery notes and quotations built with QWeb templates, plus management reports and dashboards that pull data from several apps.
- Automation: scheduled actions, server actions and automated rules that remove repetitive manual steps, for example creating purchase orders from low stock or sending reminders before contracts expire.
- Website and portal features: custom website pages, eCommerce behaviour and customer or supplier portal screens.
- User interface improvements: new views, widgets and fields that make everyday screens faster for your staff.
Where a requirement can be met with configuration or Odoo customisation through Odoo Studio instead of code, we will tell you. Less custom code means lower maintenance costs.
Our Odoo Development Process
Good Odoo development is as much about process as it is about code. Every development project follows the same steps:
- Requirement specification: we document what the feature must do, who uses it and how success will be tested, and confirm that no standard Odoo app already solves the problem.
- Technical design: our developers decide which Odoo models to extend, how data is stored and how the change will behave in future upgrades, then share an estimate based on that design.
- Development in version control: code is written as separate Odoo modules in a Git repository, never by editing Odoo’s core files.
- Code review and testing: a second developer reviews each change, and automated and manual tests run in a staging database that mirrors your live system.
- User acceptance: your key users test the feature with realistic data and approve it before deployment.
- Deployment and documentation: we release the module to production at an agreed time and provide technical notes and user instructions, so the solution is not a black box.
Development Standards That Protect Your Upgrades
The biggest risk with custom Odoo code is that it becomes expensive to maintain when Odoo releases a new version. We reduce that risk with a few firm rules:
- Inherit, do not overwrite: we extend Odoo’s models and views through inheritance, so standard functionality and security fixes keep working.
- Follow Odoo’s coding guidelines: consistent structure, naming and manifest files make modules easier for any Odoo developer to understand.
- Respect access rights: every new model has access rules and record rules, so users only see the data their role allows.
- Think about performance: we avoid unnecessary database queries in loops and test with realistic data volumes.
- Keep modules small and focused: one purpose per module makes testing, upgrading and removing features simpler.
When it is time to move to a newer Odoo release, our Odoo migration services in the UK port your custom modules and data together.
Odoo Development for UK Requirements
UK companies often need Odoo to work with local systems and rules. Our development services cover requirements such as:
- VAT and Making Tax Digital: Odoo Enterprise’s UK localisation handles VAT returns to HMRC; we build custom VAT and management reports where your accountant needs a different view of the figures.
- Payroll and HR links: integrations or journal imports from UK payroll software, so salary costs land in the right accounts.
- Banking and payments: bank statement imports, payment file exports and connections to the payment providers you already use.
- Shipping: connectors for carriers where no standard Odoo integration exists, with labels and tracking numbers generated from delivery orders.
- Marketplaces and online stores: syncing products, stock and orders between Odoo and the channels you sell through.
- GBP and multi-currency: reports and documents that show pounds sterling alongside foreign currencies for overseas customers and suppliers.
What Affects the Cost of Odoo Development
We estimate each piece of development from its technical design rather than using fixed packages. The main factors are:
- the complexity of the business logic and how many Odoo apps the change touches;
- the number of integrations and how well documented the other systems’ APIs are;
- the amount of data involved and any performance requirements;
- testing, documentation and training needs;
- your hosting platform: custom Python modules run on Odoo.sh or your own servers, but cannot be installed on Odoo Online.

A professional developer makes sure your ERP development, customisation and integrations are accurate and efficient, and that your system can grow with your business.
Yes. With professional Odoo integration, it can be connected to CRM systems, eCommerce stores, accounting tools and other third-party applications.
Odoo reduces costs, improves productivity, enhances reporting and centralises operations, giving you long-term performance and scalability.
Custom modules need to be updated for each new Odoo version. We build them as separate modules that follow Odoo’s coding guidelines and never change Odoo’s core, which keeps upgrades manageable. Our migration team upgrades custom code and data together.
No. Odoo Online does not allow custom Python modules; it supports configuration and Odoo Studio only. For custom development, we recommend Odoo.sh or your own servers.
Yes. We start with a review of your existing modules, report on code quality, security and upgrade risks, and then agree a plan to fix, improve or replace them.
The cost depends on the complexity of the feature, the number of apps and integrations involved, data volumes, and testing and documentation needs. We estimate every change from a technical design and send a scoped proposal before work starts.
