As wireless network service providers and wireless portals start offering wireless data content services to end users, the problem of billing and customer service becomes rather huge. Existing billing algorithms that network providers use are relatively simple and rely on getting batch tapes and online feeds from network carriers and generating bills from these sources. The format, fields and contents of these feeds are constantly changing fast - there are no standards presently. Then there are the content providers who need to be compensated for the content. no standard formula for paying the content providers exists. Therefore, there is a new and niche business space for wireless and web billing software providers. The functionality and issues that these billing and customer service providers must address are: 

• Cater to non-standardized information formats
• Measurement of content traffic - different metrics are being used
• Allow for wireless advertising revenue accounting
• Rapid subscriber changes - adds, moves and deletions
• Class of Service (CoS) measurement
