Abstract:
The present invention relates to an on-line calculation method of sales allowance, sales allowance calculation system and a recording medium thereof, and more specifically to an on-line calculation method of sales allowance for reflecting actual sales distributors who are granted sales allowances as well as new actual sales of subordinate distributors, and for estimating sales allowances using a conversion factor, a sales allowance calculation system and a recording medium having the on-line calculation method recorded thereon. According to the present invention, as distributors are paid sales allowances accrued by their sales, they are more encouraged to get involved in direct repurchases or sales activities so as to get more sales allowances; in this manner, income levels of the distributors will increase, and so will the value of sales allowance as a household financial asset, and the distributors then grow reliance/affection on/for the company. The company in turn benefits from an increase in sales and an increase in the number of distributors, and can always grant to the distributors allowances based on a fixed rate according to sales, irrespective of the enlarged organization, increased revenue, etc. due to an increased number of distributors and can thus avoid overpayment so as to maintain financial stability of the company.
