Supply Chain Relationships in B2B

B2B private e-marketplace provides a company with high supply chain power and high capabilities for online interactions

A public e-marketplace provides a business with high buying and selling capabilities, but results in low supply chain power

Using an intermediary results in low supply chain power and buying/selling capabilities

25

Supply chain relationships in B2B

Supply chain process consists of a number of interrelated subprocesses and roles

acquisition of materials from suppliers

processing of a product or service

packaging it and moving it to distributors and retailers

purchase of a product by the end consumer

26

Benefits of B2B

27

Benefits of B2B (continued)

Reduces marketing and sales costs (for sellers)Reduces inventory levels and costsEnables customized online catalogs with different prices for different customersIncreases production flexibility, permitting just-in-time deliveryReduces procurement costs (for buyers)Facilitates mass customizationProvides for efficient customer serviceIncreases opportunities for collaboration

Major benefits of direct sales are:Lower order-processing costs and less paperworkA faster ordering cycleFewer errors in ordering and product configurationLower search costs of products for buyers Lower search costs of finding buyers for sellersSellers can advertise and communicate onlineLower logistics costs Ability to offer different catalogs and prices to different customers

35

Selling via Auctions

Using auctions on the sell side

Revenue generation

Cost savings

Increased page views

Member acquisition and retention

36

Selling via Auctions (cont.)

Selling from the company’s own siteThe company will have to pay for infrastructure and operate and maintain the auction site

If then company already has an electronic marketplace for selling from e-catalogs, the additional cost may not be too high

37

Using intermediaries

An intermediary may conduct private auctions for a seller, either from the intermediary’s or the seller’s site

A company may choose to conduct auctions in a public marketplace, using a third-party hosting company

38

Benefits of using intermediaries

no additional resources are requiredauction set up to show the branding (company name) of the merchant rather than the intermediary’s nameintermediary does the work of:

controlling data on Web traffic, page views, and member registrationsetting all the auction parameters (transaction fee structure, user interface, and reports)integrating the information flow and logistics

39

One-from-Many: Buy-Side Marketplaces and E-Procurement

Buy-side e-marketplace: A corporate-based acquisition site that uses reverse auctions, negotiations, group purchasing, or any other e-procurement method

40

Procurement methods

Buy from manufacturers, wholesalers, or retailers from their catalogs, and possibly by negotiation

Buy from the catalog of an intermediary that aggregates sellers’ catalogs or buy at industrial malls

Buy from an internal buyer’s catalog in which company-approved vendors’ catalogs, including agreed upon prices, are aggregated

41

E-Procurement

e-procurement: The electronic acquisition of goods and services for organizations

42

E-Procurement

Conduct bidding or tendering (a reverse auction) in a system where suppliers compete against each other

Buy at private or public auction sites in which the organization participates as one of the buyers

Join a group-purchasing system that aggregates participants’ demand, creating a large volume

Collaborate with suppliers to share information about sales and inventory, so as to reduce inventory and stock-outs and enhance just-in-time delivery

43

Inefficiencies in traditional procurement management

Procurement managementThe coordination of all the activities relating to purchasing goods and services needed to accomplish the mission of an organization

Maverick buyingUnplanned purchases of items needed quickly, often at non-pre-negotiated, higher prices

44

Benefits of e-procurement

Increasing the productivity of purchasing agents

Lowering purchase prices through product standardization and consolidation of purchases

Improving information flow and management

45

Benefits of E-Procurement (cont.)

Minimizing the purchases made from noncontract vendors. Improving the payment process

Establishing efficient, collaborative supplier relations

Ensuring delivery on time, every time

Reducing the skill requirements and training needs of purchasing agents

Reducing the number of suppliers

Streamlining the purchasing process, making it simple and fast

46

Benefits of E-Procurement (cont.)

Reducing the administrative processing cost per orderImproved sourcingIntegrating the procurement process with budgetary control in an efficient and effective wayMinimizing human errors in the buying or shipping processMonitoring and regulating buying behavior

47

Implementing E-Procurement

Implementing e-procurement—major e-procurement implementation issues

Fitting e-procurement into the company EC strategyReviewing and changing the procurement process itselfProviding interfaces between e-procurement with integrated enterprisewide information systems such as ERP or supply chain management (SCM)

48

Implementing E-Procurement (cont.)

Coordinating the buyer’s information system with that of the sellers; sellers have many potential buyers

Consolidating the number of regular suppliers to a minimum and assuring integration with their information systems, and if possible with their business processes

49

Buy-Side E-Marketplaces: Reverse Auctions

One of the major methods of e-procurement is through reverse auctions (tendering or bidding model)

request for quote (RFQ): The “invitation” to participate in a tendering (bidding) system

The reverse auction method is the most common model for large MRO purchases as it provides considerable savings

50

Reverse Auctions (cont.)

Conducting reverse auctionsThousands of companies use the reverse auction model

They may be administered from a company’s Web site or from an intermediary’s site

The bidding process may last a day or more

Bidders may bid only once, but bidders can usually view the lowest bid and rebid several times

51

Reverse Auction: The Process

52

Other E-Procurement Methods

Internal marketplace: The aggregated catalogs of all approved suppliers combined into a single internal electronic catalog

53

Benefits of internal marketplaces

corporate buyers quickly find what they want, check availability and delivery times, and complete an electronic requisition form

reduce number of regular suppliers

easy financial controls

54

Other E-Procurement Methods (cont.)

Industrial mallsDistributors that aggregate products from hundreds or thousands of suppliers in one place

Horizontal—carrying MRO (nonproduction) materials for use in a variety of industries

Vertical—carrying products used by one industry but at various segments of the supply chain

55

Other E-Procurement Methods (cont.)

E-auctionssellers are increasingly motivated to sell surpluses and even regular products via auctions

e-auctions provide an opportunity to buyers to find inexpensive or unique items fairly quickly

56

Other E-Procurement Methods (cont.)

Group purchasing: The aggregation of orders from several buyers into volume purchases so that better prices can be negotiated

57

Exhibit 5.8 The Group Purchasing Process

58

Other E-Procurement Methods (cont.)

Internal aggregation—companywide orders are aggregated using the Web and replenished automatically

External aggregation—provide SMEs with better prices, selection, and services by aggregating demand online and then either negotiating with suppliers or conducting reverse auctions

59

Other E-Procurement Methods (cont.)

Purchasing direct goodsE-purchasing direct goods allows buyers to:

get them faster

reduce the unit cost

reduce inventories

avoid shortages of materials

expedite their own production processes

60

Other E-Procurement Methods (cont.)

Electronic barteringBartering exchange: An intermediary that links parties in a barter; a company submits its surplus to the exchange and receives points of credit, which can be used to buy the items that the company needs from other exchange participants

61

Infrastructure for B2B

Major infrastructures needed for B2B marketplaces

Telecommunications networks and protocols

Server(s) for hosting the databases and the applications

Software for various activities for executing the sell-side activities, buy-side activities, PRM, and building a storefront

Security for hardware and software

62

Other E-Procurement Methods (cont.)

IntegrationIntegration with existing internal infrastructure and applications

EC applications of any kind need to be connected to the existing internal information systems

Integration with business partnersEC can be integrated more easily with internal systems than with external ones

63

Managerial Issues

1. Can we justify the cost of B2B applications?

2. Which vendor(s) should we select?

3. Which B2B model(s) should we use?

4. Should we restructure our procurement system?

64

Managerial Issues (cont.)

5. What restructuring will be required for the shift to e-procurement?

6. What integration would be useful?

7. What are the ethical issues in B2B?

8. Will there be massive disintermediation?
