Can someone please list the maintenance costs of an application?
How can anyone other than the developer know this? Maintenance cost is a function of the complexity of the app and the number of support people required, multiplied by the number of customers who need help. Almost impossible to guess in advance.
The price for your app can also only be determined by you as a function of the devlopment cost, the number of users, and the time period in which you hope to recover your costs. You also need to pitch it not too far above the competition unless you are certain that it's a killer app that will sweep the board.
