Custom Odoo modules
Odoo customization for exactly what your business needs.
When standard Odoo almost fits, we build the missing piece as a clean add-on module, so you keep the parts that work and can still upgrade later.

What we build
The missing piece, built as an add-on.
- Workflows and approvals. Multi-step approvals, delegation, and automatic actions tied to your rules.
- Industry modules. HRMS extensions, property and tenancy management, project-based billing.
- Dashboards and reports. Management dashboards, statutory and custom PDF reports, scheduled exports.
- Portals. Customer, vendor and employee self-service on Odoo's portal.
- Third-party apps. Integrations with payment gateways, banks, couriers and other systems. For systems beyond Odoo, see Custom Software Solutions.
How we keep modules upgrade-safe
Custom code is where Odoo projects get expensive later. We extend Odoo through its inheritance system instead of editing core files, keep each feature in its own module, and write tests for the logic that matters. When a new Odoo version arrives, the work to move forward is visible and bounded.
How a module project runs
- A short written specification with screens and rules, agreed before coding
- Development in short cycles, each reviewed on a test system
- Hand-over with source code, documentation and a short training session
When modules are part of a wider rollout, they follow our implementation methodology.
Before writing code
Configure, customize or integrate?
Custom code is the most expensive way to change Odoo, so we look for the simplest option that meets the need. Each requirement gets one of three answers.
Configure standard Odoo
Many needs are met with settings: approval rules, extra fields, automated actions, email templates and report layouts. No code means nothing extra to maintain at upgrade time.
Best for: fields, simple rules, layouts and notifications.
Build a custom module
When the logic is specific to your business, such as a commission formula, a tenancy contract or a multi-level approval with delegation, we write an add-on module that extends Odoo without changing its core.
Best for: business rules, new documents and industry processes.
Integrate another system
When the data lives elsewhere, such as a bank, a payment gateway, a courier or an online store, a connector moves it in and out of Odoo automatically, with a log of every sync.
Best for: payments, shipping, marketplaces and older systems.
What a module specification contains
Before development starts, you receive a short written specification to approve. It keeps cost and scope clear, and later becomes the module’s documentation.
- The problem. What the team does today and why standard Odoo doesn’t cover it.
- Screens and fields. Sketches of the forms, lists and reports the module adds.
- Rules. Calculations, approvals, access rights and what happens in edge cases.
- Acceptance tests. The scenarios your team will run to confirm it works.
You own the code
The modules we build for you are yours. You get the full source code in your own repository or on your server, along with its documentation. You aren’t tied to us: any experienced Odoo developer can read, maintain and extend it. Most clients keep us on for upgrades and new features because we already know the code, not because they have to.
Mistakes we design out
- Editing Odoo’s core files. Changes made directly in core code are lost or broken at the next update. Ours live in separate modules.
- One giant module. Bundling every feature together makes each later change risky. We keep features in small, separate modules.
- Duplicating standard features. Rebuilding something Odoo already does creates two ways of working. We check standard apps and the Odoo App Store first.
- Untested data changes. Modules that change existing records are run on a copy of your database before production.
- No documentation. Every module ships with its specification, setup notes and source code, so any Odoo developer can maintain it.
Odoo versions and hosting
We build for Odoo Community and Enterprise, on Odoo.sh or your own servers. Odoo Online, the hosted SaaS version, doesn’t accept custom Python modules, so if you need one we’ll explain the move to Odoo.sh or your own server first. For the differences between editions, read Odoo Community vs Enterprise.
Modules that are part of a wider rollout follow our ten-stage implementation process. After hand-over, an Odoo support plan keeps them working through version upgrades.
Questions clients ask
Common questions.
Will custom modules block future Odoo upgrades?
Not if they're built as proper add-ons. Upgrades still need testing and some adjustment, and we estimate that effort for you before each version move.
Can you change a module another vendor wrote?
Yes. We review the existing code first, then quote the change and any clean-up it needs.
Do we own the code?
Yes. Custom modules built for you are handed over with source code.
How are custom Odoo modules priced?
Custom modules are quoted per module or as development sprints. You get a written proposal with the scope and price before any work starts.
Can you connect Odoo to our other systems?
Yes. We connect Odoo to payment gateways, couriers, marketplaces, banks and your own software through REST or XML-RPC APIs, so each record is entered once and stays in step everywhere.
