If you check out local banks versus branches of national banks, you will probably find better deals for your new checking account. Don't just pick the bank closest to you if you can find a better deal a couple of miles away as you will find that you're only going to need to go to the bank once or twice a month in the beginning. Most of the money will come in at you monthly meetings. To begin with, order a small sized checkbook as that is the least expensive, the kind that is commonly used for household accounts. Make all deposits into the account and pay all checks out of the account.
Some groups have a tendency to use the cash that comes in to pay small expenses.
Record keeping will be much easier when the trail of income and expenses is clean. It is always a good idea to set up your accounting in Quickbooks or Quicken. Then, the next treasurer can receive a disk with the history of the group's finances on it instead of reams of paper. Quicken and Quickbooks also make clear accounting records for the treasure to present to the group at the monthly meeting. A copy can be printed out for the president to review or an assistant treasurer.
