For example, each household has paid 2,500 yuan in overhaul fund, and there are 600 households with a total amount of 1.5 million yuan. A few years later, the elevator in Building 2 broke down and it cost 270,000 yuan to fix it. The elevator company will issue a maintenance invoice of 270,000 yuan to the developer (or property management company). At this time, the overhaul fund of this community will have a surplus of 6.5438+0.23 million yuan. You only have a receipt of 2500 yuan in your hand, so it is impossible to issue you an invoice.
