As an official Odoo Silver Partner with certified Odoo consultants, we customize Odoo Community and Enterprise on Odoo Online, Odoo.sh or your own servers, for companies in the UK, Saudi Arabia and other markets. [Book a free consultation](https://ozonlayer.com/contact-us/) [See our case studies](https://ozonlayer.com/case-studies/) Studio & code No-code and custom modules CE & EE Community and Enterprise Silver Official Odoo partner Scope What we customize - Forms, lists and Kanban views - Fields and data structure - PDF reports and documents - Workflows, approvals and automation rules - Dashboards and spreadsheets - Access rights, portal and website forms Configuration and Studio work on Odoo Online; custom modules need Odoo.sh or your own servers. What we customize ## What Do Odoo Customization Services Include? Odoo customization services **change how Odoo looks and behaves for your users**, without rebuilding what the standard apps already do. Most work falls into six areas. Screens ### Forms, lists and views New fields, reordered tabs and buttons, Kanban stages and list columns, so each screen shows what your team needs. Documents ### Reports and documents Branded quotations, invoices, delivery slips and certificates, built in the Studio report editor or as QWeb templates. Workflow ### Workflows and approvals Statuses, approval steps and limits that match how your company signs off orders, purchases and expenses. Automate ### Automation rules Rules that send emails, schedule activities or update records when a condition is met, so routine steps happen on their own. Insight ### Dashboards and spreadsheets Spreadsheet dashboards with pivot tables, charts and global filters on live Odoo data. Access ### Access rights and portal User groups and access rights for each role, plus portal pages and website forms for customers and suppliers. How we work ## How Does an Odoo Customization Project Work? Every request follows six steps, so **changes reach your live database only after your key users have approved them**. Small changes move through the steps quickly; larger packages are delivered in phases, one department at a time. [Odoo development services →](https://ozonlayer.com/odoo-development-services/) ![Six-step Odoo customization process: requirements and fit-gap, choose the approach, build on a test copy, user testing and sign-off, deploy and train, review at each upgrade](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-customization-process-6-steps.webp) 01 ### Requirements and fit-gap We map the process, collect examples of the screens and documents you use, and check what standard Odoo already covers. 02 ### Choose the approach Each change is matched to configuration, Odoo Studio or a custom module, and you receive a written estimate. 03 ### Build on a test copy Changes are made on a copy of your database first, never directly on live data. 04 ### User testing and sign-off Your key users test every change with real examples and approve it before it goes live. 05 ### Deploy and train Approved changes are moved to your live database, documented and explained to the people who use them. 06 ### Review at each upgrade Customizations are checked and adjusted when you move to a new Odoo version. See [Odoo support](https://ozonlayer.com/odoo-support-services/). No-code or code ## What Can Odoo Studio Do, and When Do You Need Code? **Odoo Studio covers many customizations without code**; a custom module is needed when Odoo must do something new. We recommend an approach for each change and explain the trade-offs in cost and upkeep. ![Comparison of configuration, Odoo Studio and custom modules: only custom modules need code and add new business logic, configuration and Studio work on Odoo Online, and Studio needs Odoo Enterprise](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-configuration-studio-custom-module-comparison.webp) ### Studio: fields and views Add fields, reorder buttons and tabs, change list columns and Kanban stages, and hide what users do not need. ### Studio: automation rules Send emails, schedule activities, update records or, in Odoo 20, start activity plans when a condition is met. ### Studio: PDF reports Adjust quotation, invoice and delivery slip layouts in the report editor, with your branding and extra fields. ### Studio: approval rules Require a manager’s approval before an action, such as confirming an order, can run. ### Code: new business logic Complex calculations, new data models and changes to standard behaviour need a custom module. ### Code: Community and integrations Odoo Community does not include Studio, and integrations with other systems need code. See [Odoo integration services](https://ozonlayer.com/odoo-integration-services/). Latest release ## What Does Odoo 20 Add for Customization? Odoo 20 was released in September 2026, and **Studio can now do more without code**. Highlights from the official release notes: - **Report editor:** a new interface that warns when an element is shared across PDF reports, Many2many fields in PDF reports, and report translations in one block; - **Forms and lists:** drag buttons, smart buttons and tabs to reorder them, customize Kanban stages from the form view, and set list column widths; - **Automation:** automation rules can trigger activity plans, and automated actions can trigger AI agents and send Sign requests; - **Spreadsheets:** print settings, pivot table styles and domain filters, default global filters and new chart types; - **Access rights:** record rules are removed and a domain is set on each access right, so custom security needs reviewing when you upgrade. Some features depend on your edition; see the [official Odoo 20 release notes](https://www.odoo.com/odoo-20-release-notes). Moving an older database to Odoo 20? Your customizations are checked and adjusted as part of the upgrade.

Feature names come from the official Odoo 20 release notes. Upgrade-safe ## How We Keep Odoo Customizations Upgrade-Safe Every customization has to keep working when Odoo changes. **Four rules keep upgrades predictable.** ![Example customization register checked for Odoo 20: a branded quotation layout built as a Studio report, a purchase approval rule, an overdue invoice automation rule and a branch stock transfer custom module](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-customization-register-upgrade-check.webp) Standard ### Standard first A change is made only when standard Odoo cannot meet the requirement, so there is less to maintain. Simplest ### Simplest tool Configuration before Studio, and Studio before code, because each step adds upkeep. Register ### One list of changes Every customization is recorded with what it does, where it lives and who asked for it. Upgrade ### Tested at each upgrade The list is checked on a copy of the upgraded database before you move to a new Odoo version. Before you start ## How Should You Prepare an Odoo Customization Request? A clear list of changes **gives you a more accurate estimate and a faster start**. Not sure what to change first? Our consultants can review your processes and recommend priorities. [Odoo consulting services →](https://ozonlayer.com/odoo-consulting-services/) 01 ### List the changes Write down each change you need and why, and mark which are essential and which can wait. 02 ### Share examples Add the forms, documents, spreadsheets or screenshots you use today, and the result you expect. 03 ### Name key users Choose a key user in each department who can explain the process and test the changes. 04 ### Confirm version and hosting Tell us your Odoo version, edition (Community or Enterprise) and hosting: Odoo Online, Odoo.sh or your own servers. 05 ### Agree what stays standard Decide where your team can adopt Odoo’s standard way of working instead of changing it. Timeline and cost ## How Much Does Odoo Customization Cost? **It depends on scope.** A new field, report layout or automation rule is usually a short piece of work; a package of workflow changes or a custom module takes longer and is often delivered in phases. ### What affects cost and timeline - the number of changes and the apps they touch; - whether Studio is enough or code is needed; - the number of reports and document layouts; - your Odoo version, edition and hosting; - the testing and training needed; - how the changes will be maintained at future upgrades. Odoo Enterprise subscriptions, which include Studio, are billed separately from customization work. [Request a customization estimate →](https://ozonlayer.com/contact-us/) ### Typical request sizes These examples are indicative; your estimate confirms scope after the requirements step: - **Quick change:** a new field, a list or form adjustment, or a branded report layout; - **Workflow package:** approval steps, automation rules and a dashboard for one department; - **Larger customization:** changes across several apps, including custom modules, delivered in phases. You receive a written estimate before any work starts. Case studies ## Odoo Customization Projects We Have Delivered Examples from different industries.

Our team replies to every enquiry with a straight answer on scope, timeline and budget. [Ask a customization expert](https://ozonlayer.com/contact-us/) **What are Odoo customization services?** Odoo customization services adapt Odoo ERP to the way a company works: fields and screens, reports and documents, workflows, approvals, automation rules, dashboards and access rights. OzonLayer uses standard configuration and Odoo Studio first, and builds custom modules where code is needed. **What is the difference between configuration, customization and development in Odoo?** Configuration uses the settings the standard apps already provide. Customization changes how Odoo looks and behaves for your users, often with Odoo Studio. Development builds new functionality in code, such as custom modules and integrations. Most projects use a mix of all three. **Can Odoo be customized without coding?** Yes. Odoo Studio, part of Odoo Enterprise, lets you add fields, change views, edit PDF reports, create automation rules and add approval rules without code. Changes that need new business logic, or databases on Odoo Community, need a custom module. **Can we customize Odoo Online?** Yes, with configuration and Odoo Studio. Odoo Online does not allow custom Python modules, so customizations that need code run on Odoo.sh or on your own servers. **Will customization affect future Odoo upgrades?** Every customization has to be checked when you upgrade. Configuration and Studio changes usually need less work than custom modules, which must be upgraded for each new version. Keeping a list of every customization and testing it on a copy of the upgraded database makes upgrades predictable. **How much does Odoo customization cost?** Cost depends on the number of changes, the apps they touch, whether Studio is enough or code is needed, and the reports, testing and training involved. You receive a written estimate after the requirements step. Odoo Enterprise subscriptions are billed separately. **How long does Odoo customization take?** A new field, report layout or automation rule is usually a short piece of work, while a package of workflow changes or a custom module takes longer and is often delivered in phases. We confirm the timeline in the estimate, including time for testing by your team. **Can you customize Odoo reports and invoices?** Yes. Quotations, invoices, delivery slips and other PDF documents can be changed in the Studio report editor or built as QWeb templates in a custom module. Odoo 20 adds a new report editor and lets you add Many2many fields to PDF reports. **Can you add approval steps to Odoo?** Yes. Studio approval rules can require a manager to approve an action, such as confirming an order, before it runs. Larger approval flows can use the Approvals app or a custom module, and Odoo 20 adds expense limits per job position. **What does Odoo 20 change for customization?** Odoo 20 adds a new Studio report editor, drag-and-drop ordering of buttons and tabs on forms, Kanban stage customization from the form view, list column widths and automation rules that trigger activity plans. Record rules are replaced by domains on access rights, so custom security should be reviewed when upgrading. **Do you customize Odoo Community and Odoo Enterprise?** Yes, both. Odoo Studio is part of Odoo Enterprise, so on Odoo Community the same changes are made in custom modules. We confirm your edition and hosting before recommending an approach. Official Odoo Silver Partner ## Make Odoo fit the way your company works Tell us which screens, documents and workflows you want to change, and which Odoo version and hosting you use. We will review your list and send you a written estimate with the recommended approach.
