Step 1:
Under Accounting on the left, click BILL.

Step 2: Click on the Review button or the Invoice number of the bill you would like to approve.

Step 3: Click APPROVE if the bill is correct or REJECT to send it back to the previous approver to make necessary changes.

NOTE: If the bill is rejected, a window will open. You will have to enter a reason for rejecting, which can be viewed by the employee. 

Step 4: Sign in the window that appears by holding the left mouse button if you are signing on a desktop computer or by using your finger if on a mobile device.  NOTE: Your signature will be saved for future approvals after you have completed this step once.

NOTE: The accountant can make any changes necessary prior to committing the bill  after it's been completely approved by clicking on the invoice number, making edits, then clicking SAVE.
