Working capital loan is a short-term loan, which aims to meet the short-term capital needs of borrowers in the process of production and operation, such as purchasing raw materials, paying employees' wages and accounts payable. It is usually used for daily business activities and liquidity support, not for purchasing fixed assets or making long-term investments. If you plan to buy sanitation vehicles, you need to apply for a fixed asset loan from the bank. Fixed assets loan is a kind of loan specially used to buy long-term assets, such as machinery and equipment, real estate or vehicles. You need to submit relevant documents and certificates for purchasing sanitation vehicles to the bank, such as purchase contracts, invoices, vehicle certificates, etc. The bank will examine and approve the loan according to your credit status, repayment ability and loan purpose, and determine the loan amount and loan term.
