The finance division aims to support student achievement by enhancing the district's fiscal responsibility, supporting school operations, and strengthening community relations. Finance oversees three key funds – the general fund, capital projects, and special funds, including state and federal grants and student activity accounts. Other finance responsibilities include collaborating with internal divisions and schools to effectively manage the annual budget, accounting, audits, financial reporting to state and federal bodies, funds and debt management, payroll, benefits, procurement, and accounts payable.

The finance department at City Schools of Decatur manages three major funds of the district – the general fund, capital projects, and special funds (state and federal grants, as well as student activity accounts).  The finance department is responsible for the annual budget, accounting, auditing, financial reporting to state and federal agencies, cash management including any debt, payroll, benefits, purchasing, and accounts payables.  Many of these functions are interdependent with schools and departments, so teamwork among principals and administrators is paramount.

All Financial presentations to the Board of Education are housed in Simbli.
