Abstract

PROBLEM TO BE SOLVED: To determine a proper delivery price according to the kind of an article and the rank of a customer by inputting data on the customer, and finding and displaying the delivery piece corresponding to the article based on the customer data. SOLUTION: Coordinate information on a position on a display which is pressed with a touch pen is inputted and the PDA outputs drawing data at the position by deciding the selected data according to the coordinate information. In this case, the delivery price corresponding to the customer data of past dealings is displayed. Further, the deduction rate is calculated from a discount delivery price and an amount of money which can be reduced is calculated from the possible deduction rate and displayed. Further, the discount amount is calculated from the reduced delivery price after the delivery price corresponding to the customer data is reduced is calculated and displayed. Consequently, a proper price corresponding to the customer data such as past dealt amount and a proper price at which no loss due to a discount more than the possible amount of discount can be determined.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a business information terminal device such as a PDA (Personal Digital Assistant) used for sales business.

[0002]

2. Description of the Related Art Due to the spread of PDAs, for example, in sales operations where customers go to customers and conduct transactions, various digital information such as customer data, product data, schedules, address books, and calendars are stored in PDAs and then go out. Sometimes it is easy to retrieve a variety of information from a PDA. The salesman extracts necessary information by designating items from various information.

[0003]

By the way, in commercial transactions, it is customary to provide products at a lower price to customers with a large transaction value than customers with a small transaction value. However, if you have a large number of customers, even if you carry a PDA that stores a variety of information as described above, how much the customer's past transaction value was in front of the customer, If the data such as whether the transaction value is higher or lower than other customers is taken out from the PDA and the payment price is presented, the business negotiation will not go smoothly.

Further, even if the data of the transaction amount of the customer is found, since the profit ratio differs depending on the type of the product, for example, a snack confectionery in a bag and a confectionery for gifts, a delivery value that does not cause loss is immediately presented. Doing so is difficult, especially for unskilled salesmen.

[0005] Also, as in sales promotion products, what percentage of the purchase price
In the case of a product that has such a margin, the same profit as the profit obtained at the original payment price can be obtained even if the payment price is reduced by the margin. However, since this percentage is a percentage based on the cost, if the delivery price higher than the cost is discounted by the same percentage, the profit obtained by the original delivery price decreases because the discount amount exceeds the margin. As described above, when the price must be determined in consideration of a large number of factors, it is almost impossible for even a skilled salesman to immediately present an appropriate price.

The present invention has been made to solve such a problem, and displays a delivery price according to customer data from customer data such as past transaction amounts, and also provides a discounted delivery price. Calculate and display the discount rate from the discount rate or the discount rate that can be discounted from the discount rate that can be discounted, and calculate and display the discount price from the discount payment price obtained by discounting the payment price according to customer data. To provide a business support information terminal device that supports the determination of an appropriate payment price according to customer data such as past transaction amounts, and an appropriate payment price that does not cause a loss due to a discount that is more than the amount that can be discounted. With the goal.

[0007]

According to a first aspect of the present invention, there is provided a business support information terminal device which stores information relating to a business performed at a customer. And means for obtaining a payment price based on customer data in accordance with the product, and means for displaying the payment price.

In the first invention, for example, customer data such as a rank corresponding to the past transaction value of the customer is input,
Based on the customer's data, you can select from a plurality of delivery prices set according to the type of product, or multiply the cost by a coefficient according to the customer's data to calculate the delivery price according to the product. Ask and display this payment. Therefore, the user can determine an appropriate delivery price according to the type of the product and the rank of the customer regardless of the skill level of the business.

A business support information terminal device according to a second aspect of the present invention, in addition to the first aspect, means for inputting the cost of the commodity, means for inputting a discount rate from the cost that can be discounted, and the discount rate Means for displaying a discount price from the payment price, means for calculating a discount rate from the payment price based on the input discount price, and displaying the calculation result of the means. And means for performing the operation.

[0010] In the second invention, for example, like a promotional product,
A percentage is obtained from the purchase price as a margin, and the discount rate at which the same profit as before the discount can be obtained even if the discount is obtained from the payment price obtained based on the customer's data, that is, the discount rate from the cost is known. In the case of a product, the discount price is displayed, and the discount rate of the discount price obtained by discounting the price determined based on the customer data is calculated and displayed. Therefore, by comparing both discount rates, the user can determine an appropriate delivery price that does not reduce the profit obtained at the initial delivery price, regardless of the skill level of the business.

According to a third aspect of the present invention, in addition to the second aspect, the business support information terminal apparatus further comprises means for calculating a discountable amount from the discount rate, means for displaying the calculation result of the means, Means for inputting a discount payment price reduced from the price, means for calculating a discount amount from the order based on the input price based on the input discount price, and means for displaying a calculation result of the means. It is characterized by the following.

[0012] In the third invention, from the discount rate from the cost,
An amount that can be discounted is calculated and displayed, and a discount amount from the order at the original payment price is calculated and displayed based on the discount price obtained by discounting the payment price obtained based on the customer data. Therefore, by comparing both discount amounts, it is possible to determine an appropriate delivery price that does not reduce the profit obtained by the initial delivery price, regardless of the skill level of the business.

According to a fourth aspect of the present invention, there is provided the business support information terminal device according to any of the first to third aspects, further comprising means for inputting a selling price when the customer sells, and the customer's selling price based on the input selling price. It is characterized by comprising means for calculating gross profit and means for displaying the calculation result of the means.

In the fourth invention, when a customer inputs a selling price when selling a product, the gross profit of the customer is calculated and displayed. Therefore, regardless of the skill level of the business,
We can do business that can make proposals, and smooth business negotiations with customers.
