How is the process implemented in B2C?
Determine transaction parameters with product
catalogs and shopping carts
  • Product Catalogs
  • Countless product catalogs exist Microsoft, IBM,
    Open Market, and many smaller players
  • ASP options exist iCat, Yahoo!
  • Razorfish tends to build product catalogs from
    scratch, so as to not limit the user experience
  • Shopping Carts
  • These combine multiple line items into a single
    purchase
  • Amazon.com has extended this idea with 1-Click
    ordering
  • Some sites offer a wish list of potential
    purchases or a collection of favorite items into
    a kit that reminds the user to reorder at set
    intervals

How is the process implemented in B2C?
Establish a secure connection using Secure
Sockets Layer (SSL)
Internet
Internet
SSL
Buyer
Seller
Payment Service Provider
1) The seller sends its certificate to the
buyers browser.
2) The buyer authenticates the seller using the
certificate and generates a session key.
3) The buyer encrypts the session key using the
sellers public key.
4) The seller decrypts the session key using its
private key.
5) SSL established. The seller and buyer send
secure data like credit card information using
the session key.

connections to acquiring banks and offer
value-added services to the merchant e.g. tax
calculation, warehouse integration.
The PSP approves or declines the credit card
transaction.

actions within a database transaction. If any one
of these actions fails, the entire transaction is
rolled back.

How is the process implemented in B2B?
Cost and Reliability are the primary determinants
of which package deal to select
B2B Old Days
Electronic Data Exchange (EDI)
Value-Added Network (VAN)
Cost Potentially enormous costs
Cost High setup and recurring costs Reliability
Traditional outsourcing benefits (reliability,
support, faster time to market, value-add)
B2B Future
Extensible Markup Language (XML)
Virtual Private Network (VPN)
Cost Much cheaper to implement, and more
flexible than EDI
Cost Cheaper than VANs Reliability Relatively
new technology
20
How is the process implemented in B2B?
Payment is made through Purchase Orders or ACHs
Purchase Orders (PO) and Automated Clearing House
(ACH) transactions are more common than credit
card transactions.
Purchase Orders require the trading partners to
set up the relationship beforehand. Settlement
goes through traditional channels.
ACH carries fixed transaction fees, which become
very cost efficient with larger transaction
amounts. However, refused charges and settlement
can take 48 hours, so terms need to be set up
beforehand.
