It depends on client requirements. If our client has a sharp technical background and confidence to run the app as an admin, we appreciate it much. But you know, a lot of people are not that technical to run or maintain an app because it needs deep skills and knowledge. Many customers have not enough time to maintain an app smoothly and without any malfunctioning. We have some packages where we offer upkeeps for our clients. There you can easily find the costs and axioms. Mostly, m-commerce apps need maintenance support to update regularly. Moreover, we have round clock support for our clients so you can ask anything, anytime.
