Business loans do not require maintenance fund invoices.

Commercial loans are loans used to supplement the working capital of industrial and commercial enterprises. They are generally short-term loans, usually 9 months and no more than one year at most, but there are also a small number of medium and long-term loans. This type of loan is the main component of commercial bank loans, generally accounting for more than one-third of total loans.

The house maintenance fund actually includes a special fund for house public facilities and a house maintenance fund. The special fund for housing public facilities, referred to as the special fund, is used for projects such as the renewal and renovation of the most used parts of the property, public facilities and equipment, and may not be misappropriated for other purposes.
