Leasing requires an agreement. The first step towards setting up an agreement will be made by:
租賃需要一個契約。達成一個契約的第一步就是由以下四方決定：
a) the supplier: he wishes to sell his product and sees in leasing the means of achieving this with more certainly and speed.
供貨商：供貨商希望能賣出貨物，把國際租賃看成是穩妥、快速達成目的的一種方法。
b) the lessee: he wants to buy certain equipment and sees in leasing the means to do this with few financial pressures.
租賃人：他想買某種設備，把租賃視為在很小的金融壓力達到目的的手段。
c) the bank of lessee: where it considers leasing to be the most advantageous possibility, it will advise the customer accordingly, and put him into contact with a leasing company.
租賃方的銀行：當租賃方的銀行認為租賃是最佳方法時，會通知顧客，幫助他與租賃公司達成協定。
d) the leasing company: it knows the requirements of its customers and keeps in close contact with them.
租賃公司：租賃公司了解客戶的需要並與其保持密切的聯繫。
A leasing company will need to examine the solvency of any future lessee, the reliability of the supplier and the risk on the leased product. The lessee will be asked to fill in a leasing application. The leasing company will also need to know whether the leased product will help the lessee to increase his cash flow,
etc.
租賃公司需要察看未來租賃人的清償能力、供貨商的信譽和被租賃貨物的風險。租賃人要求填寫一張租賃申請。此外，租賃公司還要了解是否被租賃的貨物會增加租賃人的現金流量。 In the process of investigating the lessee, the leasing company will have to find out whether its customer will be able to make the contractual rental payments. Besides analyzing his actual financial situation, it will also make some estimates about his future position. The lessee will, therefore, be asked to
submit his balance sheet and his profit and his profit and loss accounts for the past three years, in addition to his budget plans for the years to come.
在調查租賃人的過程中，租賃公司要調查出是否客戶能按契約規定付清租金。不僅要分析客戶目前的財務狀況，租賃公司還要預計期未來的情況。因此租賃人除了要提供今後若年的預算計畫，還要提供過去三年的資產負債表和損益賬目清單。
If the customer agrees to the leasing conditions offered to him, lessor and lessee will sign the leasing agreement which is done by way of sending back a signed copy of the offer.
如果客戶同意租賃公司提出的租賃條件，出租人和租賃人通過寄回已簽字承諾複印件的方式簽訂租賃契約。
