Build a website and web & mobile application

I would like a website where a user can signup for a company account and where they can select which modules they are interested in. Each module carries a user fee to be paid, thus each user can have different modules selected Each client must have their own database ie upon signup the Master DB copies the structure to new client in the format [login to view URL] – this is the first client record which a table in Master DB exist to keep track which email belongs to which client. Each client can by default have their own rate/user per pricing category and module – each category can be increased. Each user in the client will pay same price per module. Module pricing can be different per client although this can only be set by Probis Plus administrators The following Components forms part of this deal • Website • Web application (Chrome, Edge, Safari and other browsers) • Mobile App (not all functionality requires to exist • Language will be in English NB – source code will belong to Probis Plus exclusively and for every payment done, a complete up to date backup including source code, databases and all other information to be included.
