Lists must be made, records kept, and reports filed, and they all have to be accurate. Make an annual financial report. Pay all bills authorized by the club. Checks are signed by the treasurer and the president in some clubs. Get a receipt for every club item paid, and give a receipt to anyone who gives you money for the club.
Receipts are evidence of how the funds have been handled.
Receipts also can help answer questions about the club's income and expenses. Have specific authorization from the club before spending its money. Ask for an annual audit of the books. The treasurer's report at each meeting can be brief, but it should give the balance at the beginning and end of period for which the report covers. You will want to include the income and the expenditures.
