Hello Francis Oliver D. Cruz,

In Odoo Online 18.4+e Enterprise, the "Register Payment" button in the Expenses app has been replaced with the "Pay" button. This change aligns with the updated workflow for managing employee reimbursements. Here's a detailed explanation of the new process:

Updated Workflow for Reimbursing Employee Expenses

Submit Expense Report:

Once submitted the expense bill, these expenses await approval then approve expense report

Post Expense Report:

Click on the "Post Journal Entries" button to post the expenses to the accounting journal. After posting, a "Journal Entry" smart button appears, indicating the expenses have been recorded in the journal.

Register Payment:

Once the expenses are posted, the "Pay" button becomes available. Click on the "Pay" button to open the payment registration window.

Below I have attached screenshots provide a reference to better understand the process and where the "Pay" button appears after posting the expense.

 If you have any questions, feel free to reach out.

Hope this helps!!!

Thanks & Regards,
