Role of accounting in organizationsEdit

Accounting Management for ISPs

As the businesses, Internet service providers (ISPs) want generate revenue from providing service. Thus for ISPs, the accounting department, which manages the profit, is the functional group for companies.

Billing, collecting revenue and some supporting services are the core function of accounting management. For example, the accounting management group needs to track the usage to know who should be billed, or implement technical restrictions to enable only those who have paid use the services.


To achieve the billing management, usage statistics for users should be gathered. Using the statistics the users can be billed and usage quota (e.g. link utilization) can be enforced. Remote Authentication Dial In User Service (RADIUS), Terminal Access Controller Access-Control System (TACACS) and Diameter Protocol are examples of protocols commonly used for accounting. [2]

Accounting Management for non-ISPs

Though the non-ISP companies cannot make profit from the network and related services, the enterprise usually has the IT department which could be traded as an accounting management group.

Their jobs contain:

- measure cost effectiveness of technology to contain costs and prevent outsourcing;

- apportion costs amongst departments as their need or company’s policy;

- verify the charges from ISPs.
