Telecom Billing and Reconciliation Services
All major telcos provide billing details in some electronic form. With this data, automated comparisons can be done to you company's internal database to ensure accuracy in billing. Even if you do not have a database of your own circuits, you can still verify your being billed the correct rate and for the correct options.
Simple Custom Solutions
Enterprise systems that do everything possible within your field are too large, clumsy and require too much development time. Instead, create small discrete software that can collaborate seamlessly with the technology that the end users are currently using without requiring armies of programmers.
Create small applications that do not involve great investment in development and leverage your existing business software. One to three programmers should be able to turn out a small application in about three to six months. By writing small applications that don't take long to develop and that collaborate with existing technologies, you can recoup the costs of that development many times over.
