Abstract

PROBLEM TO BE SOLVED: To make discount management including tax calculation more complete by providing an arithmetic means which divides the discount amount of a set article proportionally into unit articles constituting the set article and makes tax calculations by the unit articles according to the proportionally divided discount amounts when the set article is registered. SOLUTION: When set PLU registration is done, the substantial discount amount by the set selling is divided proportionally according to the ratio of the unit prices of constituent PLUs. The ratio of the unit prices of the respective constituent PLUs is calculated from a specific arithmetic expression. Then the substantial dedication amount is divided proportionally at the unit price ratio of the constituent PLUs and the deduction amounts by the constituent PLUs are found by using the specific arithmetic expression. Then a sale amount considering the discount of the constituent PLUs is formed from a specific arithmetic expression. The sale amount of the PLU considering the discount which is thus found is calculated as a subtotal to be taxed, so the discount amount by set setting can be reduced from the subtotal to be taxed according to the unit price ratio of the constituent PLUs, so that an accurate tax calculation can be made.

FIG. 5C shows that the set PLU code is 101.
The data example in the case of is shown.

Normally, when sold with set PLU registration,
There are many commercial transactions in which the price is lower than when the constituent PLUs are bought individually. That is, there is a discount when buying in bulk.

To explain in this embodiment, the set product unit price of the set PLU registration is P1 (data is p1) in the setting table temporary storage memory (51), and the set product name is N1.

The configuration PLU is a product code of C2 to C5 in the setting table temporary storage memory (51), and the unit price when sold individually is P2 to P5 (data is stored in the setting table temporary storage memory (51), respectively). p2 to p5). That is, the discount amount when selling a set (d)
Is a value represented by d = p2 + p3 + p4 + p5-p1 Expression 1

When calculating the case of FIG. 5C, the discount amount d = 1000 + 4000 + 5000 + 6000-14
400 = 1600.

By the way, the tax calculation when these products are sold is calculated based on each tax rate by obtaining the taxable subtotal for each tax type in one transaction.

This embodiment has the subtotal memory for taxation and the tax amount memory (52) in FIG. 5B.

Every time a product is registered in the taxable subtotal item 5F, a target subtotal is selected from the tax type of the product and the unit price of the product is added. For example, if the tax type of a product is tax type A, T × BLA (data is t × b
and the unit price of the product at the time of registration.

T × bla = commodity unit price (pn) Expression 2 Also, the tax amount item 5F is a taxable subtotal item 5 at the end of one transaction.
From F, the tax rate is obtained with the tax rate read from the tax rate setting table (41). For tax type A, it is 10%.
In the case of the external tax system, the tax amount of the tax type A (ta × a) = t × bla * 0.1...

FIG. 5D shows PLU product codes 1, 3,
An example of data when 5 and 6 are registered is shown.

The tax calculation when registering with the set PLU, that is, the calculation for the taxable amount, allows the tax type to be set in the set PLU even if the tax type is different for each constituent PLU. The method of adding the set unit price to the taxable amount according to the tax type (hereinafter referred to as method 1) or the constituent PLU
A method of adding the unit price of a single item to the taxable amount according to each tax type (hereinafter referred to as method 2) has been adopted.

In the method 1, in the case of a combination in which the constituent PLUs have different tax types, the combinations are not correctly classified according to the tax types.

Further, the method 2 has a disadvantage that even if the classification and addition can be performed according to the tax type for each constituent PLU, the calculation for subtracting the discount amount from the taxable amount is not performed and the tax calculation is not performed accurately.

The present invention proposes a method for solving this. When the set PLU registration is performed, a means is provided for prorating the real discount amount by the set sale according to the unit price ratio of the constituent PLU.

The unit price ratio of each component PLU is obtained by the following equation.

The unit price ratio of the constituent PLUn = the unit price of the constituent PLUn / the sum of all the unit prices of the constituent PLUs Next, the real discount amount is divided by the unit price ratio of the constituent PLUn, and the discount amount for each constituent PLU is calculated by the following equation. Ask.

Amount of discount rate of PLUn = Amount of discount *
Unit price ratio of constituent PLUn Subsequently, the sales amount in consideration of the discount of constituent PLU is calculated by the following formula.

The sales amount of the constituent PLUn = the unit price of the constituent PLUn−the discount percentage of the constituent PLUn The sales amount of the PLU in consideration of the discount obtained in this way is calculated as a taxable subtotal. Discounts can be made from subtotals according to the unit price ratio of the constituent PLUs, and accurate tax calculations can be made.

The following arithmetic expression is obtained in the embodiment of the setting table temporary storage memory (51).

Unit price ratio (rn) of configuration PLUn = pn / (p1 + p2 + p3 + p4) (where n = 1 to 4) Equation 4 Discount ratio amount (dn) = d * rn (where n = 1 to 4) of configuration PLUn (5) The value (dn) obtained at this time is stored in the discount rate memory Dn.

The sales amount (pdn) of the constituent PLUn = pn−dn Equation 6 In the calculation for the taxable subtotal, assuming that the tax type of the constituent PLUn is A, t × bla = t × bla + pdn Equation 7 Becomes

Setting Table Temporary Storage Memory Input Example (5
An example of calculation of the configuration PLU1 based on 3) will be described.

From equation 1, set discount (d) = 1000 + 4000 + 5000
+ 6000-14400 = 1600 From Equation 4, the unit price ratio (r1) of the configuration PLU1 1000 / (1000
+ 4000 + 5000 + 6000) = 0.0625 According to Expression 5, the discount ratio of the configuration PLU1 = 1600 * 0.0625
= 100 From the formula 6, the sales price of the constituent PLU1 = 1000−100 = 900.

The amount calculated for the taxable subtotal of the tax type A of the PLU 1 is 900.

The taxable subtotal memory and tax amount memory data example (54) is PLU01, PLU03, PLU05, PL
An example of data in the taxable subtotal memory and the tax amount memory when U06 is registered is shown.
