There is a buzz word = turn-key ap. That is an app that installs and runs and they you have a pack of youtube/? videos for all install problems that you can use to prune support calls, along with remote access ap that you send to client on the basis that you as dev or your employee are so good at this stuff that once on his desktop you can solve all problems a lot faster than chatting on the phone. The first aspect - turn key = sell and never see them again apart from the annual fee = it must have seen-all/solved-all installation bugaboos, and eveyt ime you get a new one = fixed. Unless you reach turn-key, you are a boat with a leak, double sales = 2 boats = 2 leaks and you need more people on the pumps. You need a boat with no leaks at all - as if that was ever possible, so you get as close to that as possible so you waste less time on support = more in the bank.
