Well, I have a point-of-sale software that needs to start taking online ordering. The model i want to integrate is this: server gets prices from software (at each site);server displays prices to web user;web user places order based on these prices;server sends order to pos software. Keep in mind the software is run at several locations, the web user needs to pick which location his order goes to
