What we do
Odoo Customisation Services for UK Businesses
From a single new field to a complete custom module, our developers tailor Odoo to your processes, terminology and KPIs while keeping the system easy to maintain.
Workflow customisation
We tailor Odoo apps to your internal workflows and KPIs: approval steps, automated actions, updated dashboards and features that remove manual work.
Module customisation
We adapt existing apps such as Accounting, CRM, HR and Inventory to your needs, with module enhancements, workflow changes and performance optimisation.
Custom module development
When standard Odoo does not cover a process, we build a complete custom Odoo module designed for accuracy and speed. See also our Odoo development services.
Reports and dashboards
Real-time, data-rich reports and dashboards for finance, sales, operations and management, built on live Odoo data.
Third-party integrations
We connect Odoo with online stores, payment gateways, CRM, marketing and shipping platforms through our Odoo integration services, removing data silos.
Interface improvements
Cleaner forms, responsive layouts and mobile-friendly screens that make Odoo easier to use and reduce training time.
The right level of change
Configuration, Odoo Studio or Custom Code: Choosing the Right Level
Not every change needs a developer. Good Odoo customisation starts by choosing the lightest option that meets the requirement.
No code
Configuration
Many needs are met through Odoo’s own settings, such as pricelists, routes, approval rules, taxes and email templates. No code is involved, so upgrades are unaffected.
Enterprise
Odoo Studio
Included in Odoo Enterprise, Studio lets us add fields, adjust forms and list views, build simple reports and set up automated actions without writing code.
Python & XML
Custom modules
For complex business logic, integrations or performance-critical features, our developers write modules that extend Odoo cleanly rather than editing its core.
For each requirement we explain the options and their effect on future upgrades, so you can decide with the full picture.
Common requests
Popular Odoo Customisations for UK Businesses
Some requests come up again and again in UK projects. These are typical examples of our Odoo customization services in the United Kingdom.
Need something different? Most custom Odoo modules start as one of these and grow from there.
Branded documents
Quotations, invoices, delivery notes and statements with your branding, VAT number, company registration details and bank information.
Approval workflows
Purchase, expense and discount approvals based on amount, department or supplier.
Management reporting
Margin, cash-flow and KPI dashboards built on live Odoo data in GBP and other currencies.
Sector-specific fields
Job references for construction, batch and expiry data for food and pharmaceuticals, or contract terms for service businesses.
Customer and supplier portals
Self-service access to orders, invoices, delivery tracking and support tickets.
Automations
Scheduled reminders, automatic reordering and rules that update records when key events happen.
How we work
Our Odoo Customisation Process
Every customisation follows the same controlled steps, so changes are agreed before they are built and tested before they reach your live system.
A small change can take a few hours, while a larger custom module can take a few weeks. We agree the timeline in your proposal.
Odoo support in the UK →01
Process analysis
We review your current processes in detail, identify gaps and areas for improvement, and define the most appropriate approach.
02
Scope and estimate
For each requirement we choose configuration, Studio or custom code, then send you a scoped proposal with timeline and cost.
03
Development in staging
Changes are built in a staging database, never directly in your live system, with demos so your team can give feedback early.
04
Testing and assurance
Every change goes through functional, performance and quality testing to confirm it is reliable before release.
05
Deployment and support
We release changes at an agreed time and provide continuous Odoo support, so your system keeps running reliably.
Built to last
Keeping Your Customisations Upgrade-Safe
Odoo releases a new major version every year, so customisations must be built to last. Our development standards keep the cost of future upgrades under control and make it easier for any developer to maintain your system.
Moving to a newer Odoo version? Our Odoo migration services in the UK move your custom modules and data together.

Inheritance, not core edits
We extend standard Odoo through inheritance instead of changing its core code.
02
Separate, documented modules
All custom work lives in separate, documented modules kept under version control.
03
Staging first
Each change is tested in a staging database before it reaches your live system.
04
Review before every upgrade
We review custom modules before each upgrade and remove any that newer Odoo versions make unnecessary.
Budget and hosting
What Affects the Cost of Odoo Customisation?
We quote each customisation project on its scope rather than from a fixed price list, and we tell you up front if a cheaper option will do the job.
The main cost factors
- the number and complexity of the changes requested;
- whether the work can be done with configuration or Studio, or needs custom code;
- integration with other systems and any data migration;
- your Odoo edition, version and hosting;
- testing, documentation and training requirements.
For a detailed figure, ask us for an estimate. Our Odoo price guide explains what drives a wider Odoo budget.
Read the Odoo price guide →Your edition and hosting matter
- Odoo Online: configuration and Odoo Studio changes, but no custom code modules.
- Odoo.sh: custom modules with staging environments and automated backups.
- Your own servers or UK cloud: full control over custom code, infrastructure and data residency.
- Odoo Community: custom modules are possible, but Studio is not available.
If you need custom modules and you are on Odoo Online, we can help you move to Odoo.sh or an on-premise installation.
