The Overview

The Challenge

The client was trapped in a high-cost licensing model. With 260 employees requiring basic access to submit leave and expense requests, the company was paying $6,500 per month in Odoo user fees. The vast majority of these users only needed access for 5 minutes a week, making the per-user license fee highly inefficient.

The Solution

We replaced the official Odoo portal for 90% of the staff with a custom-built mobile app. By developing a "Shadow Authentication" system, employees now interact with Odoo via a middleware API that uses a single administrative license. This allowed the company to cut their active Odoo users down to just the management team, dropping the monthly bill from $6,500 to just $750.

Annual Savings: $69,000 in Software Licensing Fees

System Architecture

A lean mobile layer that bridges 260 employees to Odoo at a fraction of the cost.

License-Free Access

Employees log in using their Company ID and a custom PIN, requiring zero Odoo "User" seats.

Automated Routing

Requests are injected directly into Odoo models, automatically linked to the correct employee record via the middleware gateway.

Manager Control

Managers continue to use the official Odoo portal to review and approve requests submitted from the mobile app.

Optimized for Speed

Designed for 30-second submissions — significantly faster than the standard Odoo web interface.

Process & Methodology

Week 1-2

Licensing ROI Analysis

Audited Odoo usage logs to identify "low-frequency" users and mapped the hr.employee data structure to understand the integration requirements.

Week 3-7

Middleware Development

Built the Express.js gateway on Vercel to handle secure request translation between the mobile app and Odoo using a single admin token.

Week 8-12

Employee Onboarding

Rolled out the app to all 260 employees and successfully deactivated 230+ Odoo Internal User accounts, locking in the savings.
