Expense Claims and Leave Requests — Approved the Right Way

Bring structured governance to HR workflows. Prevent expense validation and leave approval without proper sign-off.

Real-World Control

What happens without HR approval enforcement?

“An expense claim for €2,800 is submitted and validated by a manager in a different department. No policy check. No amount-based escalation. No audit trail. HR Control ensures the right people review every claim — automatically.”

Draft expense with Request Approval button

Submit for approval on an expense claimWhen an expense exceeds the configured threshold, the workflow is triggered automatically on submission. The employee clicks Submit — the system routes it to the right approver based on amount and department.

Hard Enforcement

Validation is blocked — no exceptions

If a manager tries to approve an expense or leave that requires workflow approval without completing the process, Odoo raises an error. There is no bypass for regular users.

Invalid Operation dialog blocking expense or leave approval

Approval blocked — workflow required firstAttempting to validate an expense or approve a leave request that hasn't completed the workflow raises this error. The system enforces the policy with no workaround for regular users.

Frequently Asked Questions

Does it work for both expense claims and leave requests?

Yes. HR Control covers both hr.expense (expense reports) and hr.leave (leave requests). Each document type has its own independent approval rules.

Can approval rules vary by leave type?

Yes. You can configure different approval chains for annual leave, sick leave, unpaid leave, or any custom leave type defined in your Odoo instance.

What happens if the approving manager is on leave?

The SLA timer triggers automatic escalation after the configured deadline. Managers can also pre-configure delegation periods before going on leave.

Is any data migration required?

No. The module integrates with standard Odoo HR data structures. Install, configure your rules, and it applies to new requests immediately.
