Have more than two signatories in the office to make sure you have two people to sign at any one time.
In the event that staff are evacuated, you may want to close accounts from the organisation's country office or head office. Ensure that there are the signatories to do so.
Decide whether each signatory is able to sign on their own or jointly with one or more others.
Consider limits on the amount of any one payment, especially when there is only one signatory. You may need to strike a balance between delays and the need for tight controls. Possibly one signatory for payments up to a limit which will cover all day-to-day expenses but two signatories for any larger payments.
Remember to cancel signatory rights immediately if a signatory stops working for your organisation. Remember that signatories go on holiday. Case study
