Custom Module Development

When standard Odoo hits a wall, custom modules break through

Odoo covers 80% of most businesses out of the box. The other 20% — the workflows that make your operation different — need custom code. We build modules that are tested, documented, and upgrade-safe.

When you need custom

Five signs standard Odoo isn't enough

Your approval chain doesn't fit standard flows

Example: Multi-level purchase approvals with dynamic routing based on cost centre, project code, and supplier category. Odoo's built-in approvals aren't this granular.

You need live carrier data inside Odoo

Example: Displaying real-time shipment status, ETA, and GPS coordinates from DHL, UPS, or a 3PL directly on the delivery order — not via a separate portal.

Your hardware talks to Odoo

Example: IoT sensors, weigh bridges, barcode scanners, or production line PLCs feeding data directly into inventory or manufacturing records.

Your reports require logic Odoo's engine can't express

Example: Multi-dimensional cost allocation, custom P&L segmentation by project and department, or consolidated group reporting across entities.

You're doing repetitive work that should be automatic

Example: Invoice matching against purchase orders with fuzzy line-item logic, automated vendor statement reconciliation, or rule-based lead routing.

What we've built

Custom modules delivered

GPS Fleet Tracking Module

Live GPS coordinates from a third-party telematics provider displayed on fleet vehicles in Odoo. Geofencing alerts and route history stored in PostgreSQL.

Custom Approval Workflow Engine

Multi-tier approval chains with dynamic assignment based on department, amount thresholds, and job title — bypassing the limitations of Odoo's standard approval module.

Multi-Warehouse Allocation Engine

Automatic purchase order allocation across 12 warehouses based on demand forecasts, stock levels, and pre-configured replenishment rules.

Automated Invoice Matching

Three-way matching of vendor invoices against POs and delivery notes using fuzzy line-item comparison. Reduced manual matching time by 80%.

IoT Sensor Integration

Real-time temperature and humidity readings from factory floor sensors fed into quality control records and triggering automated alerts on threshold breaches.

Carrier API Bridge

Unified connector for DHL, UPS, FedEx, and DPD — quote, book, label print, and tracking from a single Odoo delivery interface.

Our standards

Code you can still read in two years

Custom Odoo modules have a reputation for being fragile, undocumented, and upgrade-breaking. We set out to prove that wrong on every project.

  • OCA-compatible code style and structure
  • Unit and integration tests shipped with every module
  • Inline docstrings and README for every module
  • Upgrade-safe: no core Odoo patches, inheritance only
  • Peer code review before every merge
  • Migration scripts for data model changes

What we won't do: patch core Odoo source code. It makes upgrades a nightmare, creates security gaps, and means your system breaks whenever Odoo pushes a hotfix. We always use inheritance and extension points — that's what they're there for.

Spec your module
cost_allocation.py 
from odoo import models, fields, api

class ProjectCostLine(models.Model):
    _name = 'project.cost.line'
    _description = 'Project Cost Allocation'

    project_id = fields.Many2one(
        'project.project', required=True, index=True)
    analytic_account_id = fields.Many2one(
        'account.analytic.account')
    amount = fields.Monetary(currency_field='currency_id')
    currency_id = fields.Many2one(
        related='project_id.currency_id', store=True)

    allocated_pct = fields.Float(
        string='Allocation %', default=100.0)

    @api.depends('amount', 'allocated_pct')
    def _compute_allocated_amount(self):
        for rec in self:
            rec.allocated_amount = (
                rec.amount * rec.allocated_pct / 100
            )

    allocated_amount = fields.Monetary(
        compute='_compute_allocated_amount', store=True)
Delivery process

From spec to deployed documentation

01

Spec

We write a functional specification document covering data models, UI mockups, business rules, and edge cases. You sign off before we write code.

02

Review

Spec reviewed with your stakeholders and any Odoo technical constraints identified. Scope is locked. Changes after this point are change requests.

03

Dev

Two-week sprints with a demo at the end of each. You see working code, not status reports.

04

Test

Unit tests, integration tests, and UAT on a staging environment with your data. Test results included in the delivery package.

05

Deploy

Module deployed to production with a deployment runbook. Rollback procedure documented and tested.

06

Docs

Technical documentation, user guide, and test suite delivered as part of the project — not an afterthought.
