Odoo 18 Expenses is free in the Community edition. An employee records an expense with its receipt, groups expenses into a report and submits it; the manager approves, an accountant posts the journal entry to the right account, and the employee is paid like any other payable. What costs extra is the receipt scanning, which is an Enterprise module bought with prepaid credits.
Without proper control, small employee expenses can add up quickly and become a financial mess. Odoo 18 makes it easy to track expenses in real-time, enforce approval policies, automate reimbursements, and maintain financial transparency — all without manual spreadsheets.
Submitting and Recording Expenses
Employees can submit expenses easily via:
- Uploading scanned receipts
- Filling out expense reports manually
- Using mobile app photo uploads (snap a receipt and submit!)
Expense entries can include:
- Description
- Category (travel, meals, accommodation, etc.)
- Amount
- Currency (with automatic conversion if needed)
No more lost receipts or delayed submissions!
Expense Approval Workflows
Odoo enables customized approval flows based on company policies:
- Single or multi-level approvals (e.g., Manager ➤ Finance Team)
- Automated notifications and reminders
- Reject or return expenses for corrections
- Track who approved what, with full audit trails
This ensures accountability and prevents unauthorized spending.
Managing Company Expenses and Corporate Cards
If your team uses company cards, Odoo can manage those expenses too:
- Tag expenses to specific corporate cards
- Match card transactions to receipts easily
- Monitor spending limits and compliance
This gives finance teams clear visibility into both reimbursable and corporate spending.
Handling Employee Reimbursements
Once expenses are approved, Odoo automates the reimbursement process:
- Batch reimbursements for payroll integration
- Separate reporting for reimbursed vs unreimbursed expenses
- Payment tracking linked directly to employee records
Fast reimbursements boost employee satisfaction and trust.
Integration with Accounting and Analytics
Approved expenses flow directly into Odoo Accounting, so your books stay accurate automatically:
- Assign expenses to analytic accounts, cost centers, or departments
- Automate journal entries and VAT handling (if applicable)
- Generate expense reports by category, employee, project, or team
Better insights = better financial control.
Mobile Expense Reporting
Odoo's mobile app makes expense management effortless for employees on the go:
- Snap photos of receipts and submit instantly

- Review and approve expenses from your phone
No need to wait until you're back at the office!

Questions we get asked
Is the Expenses app free in Odoo 18?
Yes. hr_expense is LGPL-3 and part of Odoo 18 Community, covering expense products with their own accounts and taxes, expense reports, the approval step, posting to accounting and paying the employee back. The module that reads a receipt automatically and fills in the expense is separate, Enterprise-licensed, and consumes purchased credits per document.
How does an employee submit an expense in Odoo 18?
Three ways: fill in the form and attach the receipt, drag a receipt in and let Odoo create the expense from it, or email the receipt to the expenses alias with the amount in the subject line. Individual expenses are then grouped into a report, and it is the report, not each line, that goes to the approver.
Who approves an expense report?
By default the employee's manager, together with anyone holding expense approver rights. The approver can approve it, refuse it with a reason, or send it back for changes, and every move is written into the report's chatter. Only after approval does an accountant post the journal entries, which is a deliberate second pair of eyes before money moves.
How is the employee actually reimbursed?
Once posted, the expense report sits as an amount payable to that employee, and you register a payment against it exactly as you would against a vendor bill, one at a time or in a batch. If you would rather pay it with the salary, Odoo Enterprise has a payroll bridge that adds the approved amount to the next payslip.
Can expenses be charged to a customer or a project?
Yes. An expense can carry an analytic distribution, pointing it at a project, a department or a cost centre, so the cost reaches the right analytic account for profitability reporting. With Sales installed, an expense product configured to be re-invoiced at cost or at a sales price adds itself to the customer's sales order once it is approved.
