The advantages of electronic data interchange are no longer limited to large companies, because even small firms can exchange and process data such as orders, invoices, and payments using:

A. groupware.
B. an extranet.
C. spreadsheet software.
D. integrated software suites

B. An extranet

Explanation:

An extranet is private network that uses internet access to share part of its business information or operations to customers, distributors and so on. It grants access to customers, distributors, vendors and so on to the network without granting them access to the entire organization's network. So data such as invoices, orders made by third parties can be done on the organization's network without giving them full access to the entire network with the help of extranet.
