If you are an approver or admin for expense claims, you will be able to use the Bulk Reimburse function to reimburse multiple claims at one time.
Go to Team Expense > Team Expense Claims > click on the Bulk Reimburse button.
There will be a pop-up containing all of the claims that have been approved and can be manually reimbursed.
You can search by employee or expense type, or use the expense type dropdown to filter records by expense type.
Use the checkbox on the left hand side to select the records that you would like to reimburse. To select all records, check the topmost checkbox.
Once you've selected the relevant records, click on the Reimburse button in the top right to reimburse them.
