What is the title of the officer responsible for maintaining financial records within an organization?

The title of the officer responsible for maintaining financial records within an organization is "Treasurer." This role is crucial as the Treasurer oversees the financial health of the organization, including budgeting, managing expenditures, and ensuring accurate financial reporting. The Treasurer typically maintains financial records, prepares financial statements, and may be involved in fundraising activities.

The other roles mentioned, such as Secretary, President, and Chairperson, each have distinct responsibilities associated with governance and organizational management but do not specifically focus on financial record-keeping. The Secretary generally manages documentation and meeting minutes, the President leads the organization and represents it in external affairs, and the Chairperson often presides over meetings and ensures productive discussions. Hence, the Treasurer's role is uniquely aligned with overseeing financial matters, making it the correct answer.
