Odoo 17 handles expenses with the Expenses app: an employee records a line, attaches the receipt and submits a report, a manager approves it, and Finance posts it so the amount owed sits in the books as a payable to that employee. It is part of Odoo Community and posts directly into accounting, with no export or re-keying in between.
Start by activating the module:
Apps → Install "Expenses"
This adds a new Expenses dashboard to both employees and finance users, fully integrated with Accounting and HR.
Submitting Expenses as an Employee
Employees can log business expenses via:
Expenses → My Expenses → Create
Each entry includes:
- 📌 Expense description
- 📅 Date of expense
- 📄 Product or category
- 💵 Total amount and currency
Employees can add multiple lines to a report and submit it for approval with one click.
Using Expense Categories and Projects
To ensure clarity in financial tracking, use structured expense categories:
- 🚗 Travel (flight, taxi, mileage)
- 🍽️ Meals and Entertainment
- 🏨 Accommodation
- 🔨️ Office Supplies
Each category can have its own GL account, approval flow, and tax settings.
You can also link expenses to specific projects, departments, or analytic accounts.
Expense Approval Workflows
Once submitted, expense reports move through a streamlined workflow:
- 📤 Employee submits expense
- 👤 Manager reviews and approves
- 📘 Finance validates and records to accounting
- 💸 Reimbursement is initiated (manual or automatic)
Each step is logged, and approvers are notified via email or in-app alerts.
Uploading Receipts and Documents
Receipts can be uploaded directly into each expense line via:
- 📁 Drag and drop on web
- 📷 Mobile photo upload
- 🧾 Scanned PDF or email forwarding (with OCR)
Receipts are stored securely, linked to reports, and viewable by auditors and managers.
Integration with Accounting and Payments
Approved expenses flow into your books automatically:
- 📚 Expense journals are updated with correct accounts
- 💼 Vendor bills or reimbursements can be generated
- 🏦 Payments can be made via bank or payroll
This reduces data duplication and simplifies reconciliation at month-end.
Expense Reports and Audits
Finance teams can run reports to track:
- 📊 Expense by employee, department, or project
- 📆 Pending vs. approved vs. reimbursed
- 🔍 Missing receipts or rejected items
Data can be exported for audits or synced with external accounting software.
Conclusion
Odoo 17 turns expense management from a chore into a breeze. With simple reporting, fast approvals, and seamless accounting integration, your team gets reimbursed faster — and your finance team gets clean, audit-ready records.

Questions we get asked
Is the Expenses app free in Odoo 17?
Yes. Expenses is LGPL-licensed and included in Odoo Community, with categories, the approval flow, receipt attachments and posting to journal entries. The part that is not free is digitisation: automatic reading of a photographed or emailed receipt is an Enterprise feature and consumes In-App Purchase credits per document scanned.
Can employees email receipts into Odoo?
Yes. There is an expense email alias, and a photo or PDF sent to it creates a draft expense with the attachment already in place. On Enterprise, the digitisation service reads the amount, date and vendor from the image and fills the fields; without it the employee types those in before submitting the report.
How does the reimbursement actually reach the employee?
Posting an approved report creates a journal entry that records the employee as a payable. It is then settled like any other supplier payment, from a bank journal, on its own or in a batch, or added to the next payslip where Payroll is used. Odoo keeps track of which reports are paid and which are still owed.
What is the difference between an expense paid by the employee and one on a company card?
It is a field on the expense. Paid by the employee creates a debt that Odoo will reimburse; paid by the company records the cost without creating one, which is what a corporate card or a direct company payment needs. Choosing the wrong one is the usual reason a reimbursement will not reconcile later.
Can an expense be billed back to a customer?
Yes. Link the expense to a customer's sales order and mark it re-invoiceable, and it appears on that order as a line waiting to be invoiced, either at cost or at a sales price set on the expense category. That is how travel on a client engagement reaches the invoice without being retyped.
