Custom Odoo development

Custom Odoo Development and Customization Services

GetOdooAi provides custom Odoo development services for businesses whose processes don't fit standard Odoo. We build new modules, extend existing apps, design custom screens, set up approval workflows and portals, and connect Ai to your daily operations. All code follows Odoo's module standards, lives in Git, is tested in staging before it reaches your live system, and is written so future Odoo upgrades stay affordable.

Before you build

Do you need custom Odoo development?

Custom code is the most expensive way to change Odoo, so we only recommend it when the cheaper options won't do the job:

On every project we try configuration first, Studio second and custom code last. You only pay developers for the parts that really need it.

New to Odoo? Custom development usually comes after the core setup, which our Odoo implementation services cover.

Capabilities

What we build in Odoo

Custom Odoo modules

New data models and business logic for processes Odoo doesn't cover out of the box, such as equipment rental, job costing, commission rules, subscription billing variations or industry-specific compliance records.

Custom screens and interfaces

Kanban boards, Gantt views, dashboards, POS screens and form widgets built with OWL, Odoo's own JavaScript framework, so they look and behave like the rest of Odoo.

Approval workflows

Multi-level approvals for purchase orders, expenses, discounts and credit limits, with rules based on amount, department, product or customer.

Customer and vendor portals

Secure pages where customers sign quotes, track orders, raise tickets and pay invoices, and where vendors confirm POs and upload documents.

Reports and documents

Invoices with complex tax layouts, regulatory reports, packing slips, labels and scheduled Excel or PDF exports for management.

Workflow automation and Ai

Background jobs that sync data, send alerts and complete routine steps, plus Ai features such as reading vendor bills, classifying tickets, drafting replies and scoring leads. On Odoo 20 we build on its new Ai agents where they fit. See Odoo Ai and workflow automation.
Built to last

How we keep custom Odoo code upgrade-safe

The biggest hidden cost of Odoo customisation is paying to rebuild it at every upgrade. We write code to keep that cost low:

We never edit Odoo's core code

Every change is a separate module that extends Odoo, so standard updates don't overwrite it.

Every change is version-controlled and reviewed

Code lives in Git, and a senior developer reviews every change before it's merged.

Nothing reaches your live system untested

Changes go to a staging copy of your database first, where you test them.

Queries are built for scale

Database queries are indexed and tested against realistic data volumes, so screens stay fast as records grow.

Everything is documented

You get technical documentation and user guides, so you're never locked in to us.

When the next version comes out, our Odoo migration services cover moving your custom modules forward.

Process

How a custom development project works

  1. 1

    Scoping call

    We learn what you need and check whether configuration or Studio can do it first.
  2. 2

    Written specification

    Screens, fields, rules and edge cases described in plain language, with a fixed price and timeline.
  3. 3

    Build in staging

    Weekly demos so you can steer before anything is finished.
  4. 4

    User testing

    Your team tests with real scenarios and signs off.
  5. 5

    Deployment and support

    Released to production at a quiet time, with a warranty period for fixes.
Engagement models

Pricing for custom Odoo development services

Per project

Fixed-price projects

For a clearly defined module or feature, we quote a fixed price after the written specification.

Monthly

Dedicated Odoo developer

For ongoing work or a long list of changes, hire a dedicated Odoo developer who works as part of your team on a monthly basis.

Custom Odoo development FAQ

Still unsure? Talk it through with a senior Odoo architect.

Custom modules always need updating for a new major version, but modules built as clean extensions, as ours are, need far less work than code that edits Odoo's core. We can quote the upgrade work when you're ready.
