Hello everyone,

I'm currently exploring Odoo 18's HRMS suite, which includes modules like Expenses (hr_expense), Time Off (hr_holidays), Recruitment (hr_recruitment), Employees (hr), Fleet (fleet), Attendances (hr_attendance), Skills Management (hr_skills), Lunch (lunch), and Employee Contracts (hr_contract). While these modules offer robust functionality out-of-the-box, I'm interested in tailoring and extending them to create a more unique and efficient HRMS solution.

Could you share your insights on:

• Customization strategies or real-world examples where extending the default modules has significantly improved workflow efficiency.
• Ideas for integrating Odoo HR modules with other systems to achieve seamless data flow.
• Innovative features or enhancements that have set implementations apart from the standard Odoo experience.
• Best practices for managing and maintaining customizations through future Odoo upgrades.

Any advice, case studies, or success stories would be greatly appreciated. Thanks in advance for your support!
