I look after 3 small Parish Council and we put all payments on the Agenda (Salaries are consolidated as per Finacial regs) . These listed payments are approved at the meeting and a resolution is passed. In practical terms yes there is a S/O that has already been paid and a couple of odd DD that have already been paid by the time of the meeting. However, all other payments are made after the meeting. Also, all invoices/payment vouchers are taken to each meeting for the members to review before making the payment.
Nice and transparent and to be fair the payments have never been questioned. After all it's all in the file for the auditor anyway so no issues sharing with members.
