We have a somewhat specific app/module that is requested by an enterprise so we don't know how much to charge, we are able to calculate the stimate of resources & time used, but being developers we have never charged (we are paid by hour normally).
- So we have 1 product only sold to 1 enterprise, how much should be the profit based in that we can stimate the total production cost? 10% 50% 100% 300%?, also can you take care if the module/app is somewhat easy do develop versus a not easy task?
