The treasurer must give a monthly report to the management or executive committee on the income and expenses of the organisation for that month. All the books should be up-to-date for the reportback, for example, the petty cash book and the monthly cash book. The treasurer should have all the cash slips, bank statements, cheque book stubs, invoices, petty cash vouchers, receipts and so on, at the meeting in case there are questions from the committee.
