The Office of the State Auditor collaborated with representatives of small cities and townships to develop and distribute the Small City and Town Accounting System (CTAS). The program is designed to maintain accounting records and assist in bookkeeping tasks. CTAS also facilitates the submission of financial records to the Office of the State Auditor.
