I have seen this work in another group, a service group. The board holds a monthly meeting and presents requests to the finance committee and most the time they approve the expenditure at that meeting and report at the general meeting or table the issue to research (like requests for after proms run $1,ooo, so they talk to the person making the request etc.) and then report back to the board then the group. We are lucky enough to have two retired accountants aboard and the other member is a business owner, they treat our account as if it was their money.
Our PTO meets 6 times a year. This I like.
But our finance Committee only meets once for the proposed budget. One member in our Finance Committee has asked to meet every month. Our By-laws state that any descision over $100 must have a Finance Committee Meeting to Ok. For 2003-2004 yr. the executive board was going to have a meeting every month any way. by having a Finance Meeting instead is this good or asking for trouble.
