Bill - This service is used along with the Usage service. It generates Bill for a particular based on Usage Scheme. For e.g. if user sid's bill has to be seen for May and 2012. This service will list all the charging transactions and calculate the bill for May and tell the total usage and price. The calculation is done based on the Price which is given during scheme creation, the unit of charging and corresponding usage. AppTab currently just maintains the data and does calculation. How the Bill is rendered and the interface with Payment Gateway is left with the app developers.

Usage - Usage is part of AppTab which a rating, metering, charging and billing engine. This service allows app developers to specify the rate for a particular usage parameter e.g. Level - Storage - space, Bandwidth, Time, Feature, Level of game, OneTime - Which can be used for one time charging e.g. for charging for downloads and License for traditional license based charging. It provides methods for first creating the scheme for charging which specifies the unit of charging and the associated price. Subsequently a chargeXXX call has to be made for charging. e.g. If a app developers wants to charge on Storage. He can use the method createStorageCharge and specify that for 10 KB/MB/GB TB the price is 10 USD Once the scheme is created. The app developers can call the chargeStorage call whenever storage is utilized. e.g. 5MB. Using the Bill service the app developers can find out what is the monthly bill for a particular user based on his utilization

License - This service provides traditional License engine. This can be useful to app developers who want to sell their applications on license keys and want to use a license manager on the cloud. It allows to create a license for a particular app. Once the license scheme is created.
