A Volunteer Treasurer's responsibilities can vary depending on the size and nature of the charity, but ultimately your job is to work with the financial team to develop a budget and monitor and evaluate financial progress. Although this may be a paid position at larger charities, smaller organisations often seek out volunteers to spend a few hours or days a week to help guide their financial decisions and act as a voice of expertise. As Volunteer Treasurer, you'll be expected to bring a certain level of experience and know-how to the role to ensure the financial success of the organisation.
