If you are a client of a software house, e.g. like us, you probably happen to have some difficulties with accepting implementation costs of programming commissions. IT company, that will provide you with development services, seems to demand truck loads of money for small modifications. Do you know why you have such an impression? Because everything that they make is some kind of magic - the nature of problems, that are solved there is often unclear and requires specialised knowledge to be able to understand and accept it. That’s why I would like to break the spell of the most frustrating topics in software house - client line.
