Custom Odoo module development
When standard functionality is not enough, we do not configure workarounds — we develop. Python/XML modules, OWL views, QWeb reports, automations and APIs on Odoo, with a dedicated team under documented processes and code that is 100% yours.
What is Custom Odoo development?
Custom Odoo development is building what standard configuration cannot solve: your own Python modules, models and views (including OWL components), QWeb reports, process automations and integrations via XML-RPC or REST.
See in detail
Here is the key difference: most Odoo partners are configuration consultancies — great at parameterizing standard modules, but when serious development is needed, they subcontract it. iTechDev is the software factory. Odoo is Python on PostgreSQL, exactly the stack we already master across hundreds of projects. Founded in 2018 (Monterrey, Guadalajara + Texas, 100+ projects delivered), we assign you a dedicated team that works under documented, auditable processes, with code review, tests and documentation — and hands you code that is 100% yours. We do not lock you to the consultancy: we extend Odoo respecting its core so it survives version upgrades.
Customize vs configure: where development starts (and where it does not)
Half of what many sell as "custom development" already ships out of the box. We separate it honestly so you do not pay for configuration.
This is not development — we do not charge it as such
- CFDI 4.0 for income, expense, payment and transfer
- Payment complement (REP)
- DIOT and electronic accounting
- Carta Porte 3.1 for road transport (type T)
- POS global invoicing and self-invoicing
Here we do come in as the software factory
- Retailer or automotive addendas (one per customer)
- Stamped payroll (ships in no Odoo edition)
- A connector to a PAC outside the integrated ones
- Multimodal Carta Porte (sea, air, rail)
- Industry-specific logic and custom reports
- Integrations with legacy systems with no standard API
Which one applies is closed by the technical analysis: we do not quote development blind.

Legal entity in the U.S. (iTech Corp, Texas), contracts under U.S. law, same CST time zone and USMCA.
ERP with CFDI 4.0 invoicing
We implement Odoo with integrated SAT stamping (PAC), client portal and reconciliation — a full operation, not just software.
When you need it
What it includes
Custom modules in Python
Models, business logic and inheritance of standard models following Odoo conventions, without patching the core, so they survive version upgrades.
Views and UI with OWL
Forms, lists, kanban and frontend components built with the OWL framework, so your users work on interfaces shaped to their real flow.
Custom QWeb reports
PDF reports and QWeb templates (invoices, orders, fiscal or customer formats) with the exact design and data your operation needs.
Automations and workflows
Automated actions, scheduled actions (cron), validations, approval flows and business logic that removes manual steps.
XML-RPC / REST integrations
Connecting Odoo with banking, e-commerce, CRM and legacy systems via XML-RPC or REST controllers, with documented data contracts.
Legacy module refactoring
We rewrite custom modules with no documentation or tests —the ones that break with every upgrade— into clean inheritance-based development, with test coverage and core separation.
Code review, tests & QA with ARIA
Unit and regression tests, cross code review and QA backed by our internal ARIA platform, with technical documentation and code 100% yours.
How we work
1Requirement analysisDeliverablearchitecture and scope document
We review your Odoo instance (version, modules, existing custom code) and the problem to solve. We define the architecture: what to inherit, what new module, what to integrate.
2Technical designDeliverableapproved technical specification
Specification of models, views, reports and integration contracts, with the OCA vs. proprietary decision and a test plan, validated with your team before coding.
3Iterative developmentDeliverabledemonstrable functional increment per sprint
2-week sprints with mandatory code review, unit and regression tests and a functional demo on your instance each cycle.
4QA and regression testingDeliverabletest report and a module ready to deploy
We validate each module with the internal ARIA platform: unit, regression and compatibility tests against your standard and existing custom modules.
5Controlled deploymentDeliverablemodule in production without breaking the existing operation
Promotion to production in an agreed window, with a prior staging environment and a rollback plan.
6Documented delivery & handoffDeliverabledocumented repository and knowledge transfer, no black boxes, no vendor lock-in
Technical documentation, a repository with code 100% yours and post-deploy support.
Development always goes behind the analysis
We do not quote custom modules off the cuff. First the technical analysis: we review your instance, version, existing modules and the real problem, and hand you closed scope and a budget in writing. Development is quoted as closed scope —not an open bucket of hours— and the analysis is credited to the project if you move forward.
A badly-sized module gets paid for twice. We prefer a week of analysis to a budget that reopens mid-project.
Request the technical analysisWe wrote the stamping module ourselves
For our own operation on Odoo 19 Community we built the CFDI stamping connector in Python and audited it against the SAT's Anexo 20; we run it on our own instance. We do not yet claim it battle-tested in production at scale —when that is the case, we will say so—; what it does prove is that we actually do Odoo development, we do not subcontract it.

We show it to you in a demoWhat we do not promise
- Total immunity to upgrades: we extend through inheritance so it survives, not so it never has to be touched.
- That Community "invoices for free": stamping is development plus a maintenance contract for the module.
- An open bucket of hours: development ships as closed scope, quoted after the analysis.

Contact us →How are you different from a traditional Odoo partner?
Most Odoo partners are configuration consultancies: they parameterize standard modules, and when serious development is needed, they subcontract it. iTechDev is the software factory. Odoo runs on Python and PostgreSQL — exactly the stack we master across 100+ projects. We assign a dedicated team that develops under documented processes rather than improvising. That is why many partners hire us to reinforce their technical layer.
Do you respect the Odoo core and develop clean?
Yes. We do not patch the core or modify standard modules destructively: we extend through inheritance following Odoo conventions, in separate custom modules. The benefit? Your development survives version upgrades instead of breaking with every one. It all ships with tests, code review and documentation.
Do you use OCA modules or develop proprietary?
We decide without bias, based on your case. If a mature, maintained OCA (Odoo Community Association) module solves the requirement, we leverage and extend it instead of reinventing it. If none exists or it does not fit your operation, we build a custom module. What matters is the right solution, not ideology.
Does the client own the code?
Yes, 100%. All custom modules, views, reports and integrations are delivered in a documented repository, with tests, and are your property. No vendor lock-in: the code lives inside your Odoo instance and can be maintained by any competent team.
Can you reinforce my current Odoo partner without replacing them?
Yes, it is one of our most common scenarios. Your partner stays in charge of implementation, configuration and the functional relationship; we provide the development team that builds the modules, integrations and automations they do not do in-house. We work as the factory behind your partner, not against them.
Which Odoo versions do you develop on, Community or Enterprise?
Both. Custom development is built the same way on Community and Enterprise: Python modules, model inheritance, OWL views, QWeb reports and APIs work on both editions. When your case allows it, a frequent route is Community plus our custom modules as a lower license-cost alternative; we evaluate it without bias based on your operation, and we always develop respecting the core so it survives version upgrades.
