Description

System based procurement service downsizing by using network-based e-procurement service

The present invention relates to a network-based purchase service system for reducing the purchase business.

More specifically, the purchase request of the goods carried out by the company's purchasing department can be directly processed by the buyer who needs the goods online using the purchasing system, and the purchase of the purchasing department by computerizing the approval of payment for the purchase of the goods. The present invention relates to a network-based procurement service system for reducing procurement work.

In general, all purchasing requests and new product searches performed by members of each department in the company's purchasing method are made through the purchasing department. That is, in the commerce between companies, the number of items and the size of transactions of goods purchased between companies were large, so the commerce was carried out with a separate department related to purchase.

In particular, among the items purchased by the purchasing departments of the companies mentioned above, items corresponding to MRO (Maintenance, Repair, Operation), which are consumable materials of the company, have various types of goods and are ignored in importance in comparison with raw and subsidiary materials in purchasing between companies. Although the proportion of consumable materials in the total purchase cost of the enterprise is not small, the purchasing department of the enterprise receives the purchase requests for these materials in batches, makes purchase orders, receives the goods and distributes them to each department.

According to NAPM, a US purchasing research firm, repetitive procurement operations performed by each company's purchasing department account for about 70% of the total purchasing department's work.

1 is a flowchart illustrating a method of purchasing goods performed by a general company as described above.

As shown, the purchaser of a particular department who wants to purchase an item first fills out an item to purchase, a required number, and so on, and prepares a purchase application (S10). At this time, the buyer should contact the purchasing department to check the price range of the item they want to purchase. In other words, the buyer must first contact the purchasing department to obtain information about a particular product.

After completing the purchase application, the buyer performs a payment settlement procedure for the item to be purchased (S20). At this time, in order to approve the payment of the purchased item, the purchaser performs the approval process through a predetermined purchase rule according to the item or the amount, and if there is a separate approval system, after filling out all items to be purchased, the approval process ( The chain must be prepared by the applicant.

After that, the purchasing department collects the purchase application for which the payment approval is completed, classifies documents by supplier (S30), and selects a supplier to purchase the goods in consideration of the contract relationship previously made (S40).

After selecting a supplier, the purchasing department prepares a purchase order in which items, numbers, payments, and delivery conditions are entered, and delivers a facsimile, phone, document, etc. to the supplier to perform a purchase order (S50).

The supplier then accepts the purchase order via facsimile, phone, or document, checks whether the order can be responded, confirms the receipt by phone or fax, and delivers the item to the corporate purchasing department. (S60).

In addition, the purchasing department that receives the goods from the supplier distributes them to the buyer who requests the purchase of the goods and ends the purchase business (S70).

However, the purchase of goods performed by a conventional company as described above, by collecting the individual purchase application from the purchasing department at the same time, so that the purchasing department is always involved when placing a purchase order using a telephone or a facsimile. There is an inconvenience in that the daily purchasing process of the purchasing department is heavy because it is necessary to always check the latest status about the progress after that, and to purchase the goods through a strategically concluded supplier in the purchasing department. Instead of selecting suppliers immediately, it is difficult to achieve a company-wide purchase cost reduction.

In addition, since the purchase system is not fully established online, each department in the enterprise always asks the purchase department to check the price of a specific item to be purchased and who is a suitable supplier. After that, buyers of each department have to check with the purchasing department where the purchase process is currently in progress, so the work of the purchasing department becomes heavy, and the buyers of each department check the approval, ordering, arrival, etc. There is a problem that can not be efficient work.

In addition, after the purchaser of each department who wants to purchase a specific item executes a purchase request, it is required to document and approve the approval procedure according to the approved amount of the item according to the predetermined purchase approval standard. The procedure required for approval, such as finding and approving a higher payer who should be in charge of approval, or having an approval system inside, is required, and it takes too much time. Because of the high probability of making mistakes, there is a problem that the approval must be restarted from the beginning when a mistake occurs and the approval is rejected.

In addition, whenever a purchasing department places a purchase order with a specific supplier, the purchasing department must be involved and always check by telephone or facsimile. Due to the need to respond offline, such as facsimile, a lot of time and money were required for business consultation with the supplier, and a lot of working time of the purchasing department also occurred.

An object of the present invention is to solve the above-mentioned problems, the purchase request of the goods carried out by the company's purchasing department is processed by the members of the department that needs the goods directly on-line using the purchasing system at the same time It is to provide a network-based procurement service system to reduce procurement work so that the purchasing department can concentrate on the selection of a strategic supplier, which is the original task, by pursuing computerization of cost approval. .

Another object of the present invention is to provide a network-based system for reducing purchasing activities, which enables buyers of specific departments who request the purchase of goods using a purchasing system to directly check and confirm the payment approval result and order processing status of the goods online. To provide a purchasing service system.

Still another object of the present invention is to prevent inconvenience caused by existing facsimile or telephone purchases through the use of a network-based purchasing system, and to immediately respond to orders through electronic documented orders or quotation requests. The present invention provides a network-based procurement service system for reducing procurement work that can be performed to enhance the work efficiency of companies and suppliers.
