First, unify expenses and invoices, and make copies of reimbursement accounts. The invoice is set in the fixed account page of the account book.
Second, don't reflect waste in the ledger, that is to say, you can combine the expenses of communication and classmates going out to eat into the expenses of making banners and boards, and would rather make the expenses of boards much higher than usual, and don't want some money similar to communication expenses. You have to think about this for yourself according to the specific situation. Don't go too far.
Third, it is necessary to explain the reasons for all the expenses. In layman's terms, the activity can't be done without spending the money.
Fourth, sponsors' fees are vague. If the school knows how much money it has sponsored, it should be cautious. If it doesn't know, it should try to compress this part of the accounts and strive for more activity funds for the club.
That's basically it. The rest should be considered according to your own situation.
