Odoo-Based HR Management System Testing

About project

Client

As a steadily growing software company relying on Odoo for our core operations, we built a custom, multi-module ERP system, combining recruitment, HR, project management, and finance, to streamline internal workflows and meet our scalability needs. Testing the new system was an essential part of rolling out the product and ensuring smooth and confident adoption.

Challenge

As our company’s needs were changing, the limitations of existing recruitment tools became increasingly visible. What started as an internal applicant tracking system quickly grew into a full Odoo-based ERP platform combining Recruitment, HR, Project Management, Payroll, and Finance modules, each deeply interconnected and dependent on accurate data flow. This expansion significantly increased the complexity of the system and introduced a wide range of integration risks, workflow inconsistencies, and logic defects that could directly impact our internal operations.

Because we use this ERP system every day for hiring, managing employees, tracking project work, and generating payroll and client invoices, even minor defects could produce immediate business consequences. Ensuring the stability, accuracy, and reliability of such a multifaceted environment required continuous, systematic testing and close coordination across modules, environments, and teams.

Key Challenges

• Complex cross-module data flow linking Recruitment, HR, Project, and Finance
• Timesheet synchronization failures affecting payroll and invoice calculations
• Business logic inconsistencies across currencies, contracts, and salary rules
• Unstable performance when working with large volumes of HR and candidate data
• Integration issues with external services (such as HubSpot)
• High risk of permission and role–based access mistakes across HR and finance
• Environment-specific defects across DEV, BUILD, RC, and PROD
• UI and workflow inconsistencies across browsers and user roles

Solutions

To stabilize and evolve our multi-module Odoo ERP system, we implemented a continuous QA strategy that combined structured, scenario-based testing with in-depth analysis of cross-module data flows. Our QA team collaborated closely with HR, finance, and project stakeholders to refine workflows, verify logic accuracy, and ensure that every update — whether in recruitment processes, employee records, project timesheets, payroll rules, or client invoicing — behaved consistently across modules and environments. 

This approach allowed us to detect critical issues early, optimize integration points, and maintain reliable performance in an ecosystem that is actively used internally and continuously expanded with new functionality.

Key Solutions

• Running multi-environment test cycles. Testers conducted validation in DEV, BUILD, RC, and PROD to catch configuration-dependent defects early and secure stable releases.
• Building end-to-end workflow checklists. The QA team created structured approaches for recruitment, onboarding, contracts, timesheets, payroll, and invoices to ensure consistency across the entire employee lifecycle.
• Strengthening cross-module integration checks. Testers verified that updates in Recruitment, HR, or Project modules were correctly represented in Finance, preventing calculation and reporting discrepancies.
• Stabilizing timesheet synchronization logic. We traced data exchanges across modules and environments to eliminate errors affecting payroll totals and client invoice accuracy.
• Validating complex financial and HR logic. The team tested multi-currency rules, salaries, contract types, leave balances, and formulas used in payroll and billing workflows.
• Expanding exploratory coverage. We identified hidden workflow defects, edge cases, and permission issues not captured by predefined test scenarios.
• Improving external integration reliability. We tested HubSpot API payloads, data mappings, and error handling to ensure complete and accurate candidate imports.
• Refining permission and role configurations. The QA team ensured sensitive HR and finance data remained protected while maintaining smooth workflows for managers and operational teams.

Results

Through continuous testing and close collaboration with our HR, finance, and project teams, we achieved a significant improvement in the stability and reliability of our internal Odoo-based ERP system. Critical workflow defects were discovered and eliminated, financial logic became more precise, and integrations across Recruitment, HR, Project, Payroll, and Finance modules now operate predictably even under changing requirements.

Since this platform supports our daily operations — from hiring and onboarding to salary processing and client invoicing — the impact was immediate. Teams can now benefit from faster processes, fewer disruptions, and greater confidence in the accuracy of every stage of the employee and project lifecycle.
