DO NOT make cash transactions. Blank checks should never be signed by any of those authorized to sign checks. Signing blank checks can lead to the same problems individuals encounter by signing blank checks for personal accounts. It is a good practice to identify the purpose for each check, or its budget line item, on the memo line. No bills should be paid unless authorized by the membership.
Most bylaws provide for spending only a nominal amount.
Check local unit bylaws for the correct procedure to follow. Those items still must be ratified by the membership. The treasurer must balance the bank statement immediately when it is received. As an added safeguard, if a unit finds bonding too costly, mail the bank statement to another officer. That person would review it on a regular basis to be sure funds are being directed into approved areas.
