If your accounts team is processing invoices and there are some queries that they may have and they want your property manager approves them, then the accounts team can send the invoice through to the PM for approval by clicking 'Send for PM Approved.'
Invoices that are pending PM approval will show under the 'Invoice pending for property manager's approval' status in the dashboard and the property manager will receive a daily summary email informing them that there are invoices awaiting their review.
