but can you do it all at once for one app? also can you have a membership? these weren’t answered

This is great, but here all my questions, as a novice in this: I was hoping to have all these features in one app. So I can connect with them on different levels. Like chat with them and sell product, put out news/articles, and financial planing to my designers. All in one APP see your features? is all one or can i have everything in one? -Chat – Messenger (12 screen) • E-Commerce (24 screen) • Finance (15 screen) • Multi – Media (16 screen) • News – Article (16 screen) • Social (16 screen) I We are a PR/Online products firm and I would like for my clients to have access to financial statement. But customers to be able to go in and buy and read and chat with us. Is it possible to have some account have acess to everything and some people have no access? or memebership programs? That are different?

Great UI and UX. All of our team like it. But I can to confirm it that do you provide after sale service. Because we have to apply it on the app of our paintball for 200 dollars which is a sub app of our main app for the business.
