Odoo Customization & Custom Module Development
Odoo customization services from Reldanor adapt Odoo to the parts of your business that standard apps do not cover — new fields and screens, approval rules, automated actions, custom reports and full custom modules. Reldanor always starts with configuration and Odoo Studio, and writes custom code only where it adds clear value.
Every customization is documented and built to survive future Odoo version upgrades.
Who this service is for
Odoo customization makes sense when a specific process gives your company an advantage or is required by your customers, regulators or industry — and standard Odoo cannot handle it through configuration alone. Typical requests include:
- Industry-specific fields, documents and approval steps
- Custom quotation, invoice, delivery or job documents
- Automated actions that replace manual follow-ups
- Dashboards and reports for management
- New models and screens for processes Odoo does not cover
What's included
Requirement analysis
Each request is checked against standard Odoo first, so you only pay for development that is necessary.

Our process
Requirement workshop
Reldanor documents the business rule, users involved and expected result. Your preparation: bring examples of the documents or screens you need.
Solution choice
The requirement is solved with configuration, Odoo Studio or a custom module — with effort explained. Your preparation: approve the approach.

The customization is built and reviewed in a development environment.
Testing
Your key users test on staging with real scenarios. Your preparation: reserve time for testing and feedback.
Release
The change is deployed to production and documented.
How we scope your project
Customization effort depends on whether the requirement can be met with Odoo Studio or needs a custom module, how many existing apps it touches, the number of documents or reports involved and the testing required.
Reldanor estimates each customization separately after a short requirement workshop.
Every project is scoped individually — contact us for a free consultation.
Limitations and when you need something else
Customization is powerful but should be used carefully:
Frequently asked questions
What is the difference between Odoo Studio and a custom module?
Odoo Studio is a no-code tool for adding fields, views, reports and simple automations, and it works on Odoo Online. A custom module is Python and XML code that can add new logic and models; it requires Odoo.sh or on-premise hosting.
Will customizations break when we upgrade Odoo?
Customizations need to be ported to each new version. Reldanor builds them following Odoo guidelines and keeps them documented so upgrades are predictable.
Can you change a customization made by another partner?
Yes. Reldanor reviews the existing code first, then fixes, extends or replaces it.
Who owns the custom code?
The custom modules developed for your company are delivered to your repository and are yours to keep.
Do you use third-party modules?
Only when a reviewed, maintained module is clearly the better option, and only with your approval. Standard Odoo is always the first choice.
