An electronic commerce system suggesting private sale price and its commerce method {An electronic commerce system suggesting private sale price and its commerce method}

The present invention relates to an electronic commerce system capable of purchasing goods or services by paying a desired transaction price that a consumer intends to pay without disclosing a discounted sales price, and a transaction method according thereto.

In addition, the present invention relates to an e-commerce system capable of price differentiation capable of selling a sale price of one product or service at various prices without consumer resistance, and a transaction method according thereto.

In addition, it relates to an e-commerce system and a transaction method that enables a supplier-centered consumer-centered P2P service by reducing intermediary and distribution stages.

In addition, the present invention sets the transaction price condition for each individual of the seller in advance and makes it impossible to modify or delete it, so that the automatic transaction is performed without the intervention of an intermediary according to the predetermined condition, through which transaction cost and management cost due to the digitalization of the system. It relates to an e-commerce system and a transaction method that can contribute to maximizing efficiency through reduction of

The present invention is an e-commerce system that proposes a transaction price desired by an individual and a transaction method according thereto. The present invention is an e-commerce system in which the seller does not disclose the sale price in order to conduct a transaction at a high transaction price, and a transaction method according thereto. There are precedent data.

In Patent Publication 10-2001-0016321, the seller seals and inputs the desired sales price, and receives the desired purchase price from the consumer without being exposed in the product information that can be viewed by the consumer. At this time, the desired sales price entered by the seller and the desired purchase price entered by the consumer are compared, and if the consumer's desired purchase price is greater than the seller's desired sales price, a single advertisement is arranged in a row on the ad slot machine to immediately indicate that the purchase is possible.

Patent Publication 10-2017-0030913 issuing a ticket for purchasing a predetermined number of products after receiving a payment for the purchase of a ticket, providing product information that can be purchased with the ticket to a purchaser terminal, and selecting a product from the purchaser terminal. In the case where the number of selected products is selected more than the number of products that can be purchased with the ticket, the invention is published in which the purchaser terminal selects as many as the number of products that can be purchased with the ticket before delivery.

As e-commerce through the Internet becomes more common, sellers supply goods or services at discounted sales prices compared to general sales prices when a large amount of sales is secured, such as reverse auction method or joint purchase method, in order to present more competitive sales prices. In the case of distribution channels such as Gmarket and Naver Shopping, in order to encourage purchases in their own distribution channels, discount coupons are provided that are not related to sellers to induce consumers to revisit. However, such exposure of discount prices makes consumers hesitate to purchase goods or services beyond the price discounted at once through price learning, and as a result, sellers can sell at discounted prices by reducing their profits for additional sales. There will be only. As such discount competition heats up, sellers' profits continue to decrease, and eventually, sellers or producers are forced out of the market because they do not secure adequate profits. Therefore, in order to maximize customer satisfaction through the development and supply of various products or services, it is essential to secure appropriate profits for producers or sellers.

In addition, as e-commerce through the Internet has become more common, consumers are making purchases without price resistance at various prices through various distribution channels despite the same products and services. Such purchasing behavior occurs due to the difference between the consumer's ability to search for information and the amount of information, that is, information asymmetry. Therefore, in order to achieve a transaction without price resistance from consumers, the desired transaction price according to the asymmetry of information is identified, and through this, the individual consumer presents the desired transaction price, and when the transaction is made through acceptance, price discrimination and consumer satisfaction are simultaneously achieved without price resistance. Can be achieved. For example, an LG Electronics agency sells the latest laptops with a sale price of 1.5 million won through distribution channels such as Gmarket and Naver Shopping, including their offline agencies. Even though they are the same product, consumers who access through distribution channels have different purchase prices. You will buy a laptop. Offline agencies are sold for 1.5 million won as an advantage of being able to view and check products, and at Gmarket, they are sold for 1.4 million won in limited quantities and for a limited period. Naver Shopping can purchase for 1.35 million won using a 10% discount coupon provided by a distributor. have. Even though the product is the same, a difference of up to 150,000 won occurs in purchase depending on the value that the consumer prefers, such as the amount of information on the consumer's price, access route, and shopping time constraints. According to the priority, products are purchased at three different prices. However, the asymmetry of information about the purchase price of consumers is quickly resolved, and similar consumption behaviors in the future converge to the cheapest distribution channels, which is the main reason for deteriorating sellers' profitability.

In addition, even in an e-commerce environment through the Internet, since there are intermediaries or various stages of distribution between sellers and consumers, sellers and consumers are directly connected to the distribution stage through automated P2P transactions such as blockchain smart contracts. There is a need to introduce an e-commerce system that maximizes reduction and efficiency.

Therefore, for example, in the consumer user interface, if you enter 700,000 won to 750,000 won, 760,000 won to 900,000 won, or 1,000,000 won as the desired transaction price of Samsung Electronics Galaxy X and there is a stock quantity, the consumer Can be purchased.

Therefore, if 690,000 won is entered as the desired transaction price entered through the desired transaction price input unit, or 710,000 won is entered, but there is no stock in the first discount price range (25% to 30%) of 700,000 won to 750,000 won. Is the case that there is no inventory quantity corresponding to the consumer's desired transaction price.

And when there is no inventory corresponding to the total discount price of 700,000 won to 750,000 won in the first discount price section (25% to 30%) and 760,000 won to 900,000 won in the second discount price section (10% to 24%) Is the case that there is no inventory quantity of the above goods or services that meet the discount conditions.

As shown in FIG. 3, the seller may limit the discount sales period of the sales product.
