Your multi-month reimbursement request would show as pending until you are completely reimbursed. However, you will also see reimbursement approved each month.
For example, you submit your three-month gym membership of $120 ($40 each month) from 01/19 to 03/19. Your reimbursement request will show as “pending”. However, you will receive reimbursement of $40 each in January, February, and March. When you receive your last reimbursement in March, your reimbursement request will show as “completed”.
