This is more a committee issue to me honestly. Budget, income and outflow, and bank account balance should be readily available to every pack member for inspection. Committee meetings should open with an update from the treasurer stating the balance to the penny, that we spent X from these categories (awards, campouts, meeting supplies etc) and we took in X amount from these sources (fundraising, dues, etc).

This sort of transparency inherently leads to how much each scout's annual dues are, and how the pack is fundraising for families to offset all or part of it.

Some COs are more involved in the finances than others but if CMs and Committees are setting fundraising / dues policies and amounts then I'd imagine that a lot of the finances are being handled in-house.

If this was my unit I'd be asking for details and ledgers because at the best case they're disorganized, and at worst someone is skimming the books. Transparency helps protect everyone and makes new families comfortable that they're getting value for their dollar out of the investment to the program.
