According to relevant information, my query display is unnecessary. Maintenance fund receipts do not need to be changed into invoices. Do you have a receipt? The maintenance fund is a public maintenance fund, which is collected and managed by the real estate management department. It is charged by government departments, but it also belongs to all owners. The public part of the house needs maintenance and can be used with the consent of the owners and the owners' committee. After use, the property management department will pay the fee.
