Hi Folks. I'm new to ecomm and CRMs and I'm working on setting up a store. I'm planning to offer a writing-related business service. I'm trying to figure out if there's a back-end portal-type system that would allow my writers to login and upload their work, then I'd receive a notification their work was uploaded, then they'd receive a notification that i'd approved it, then they could text and/or email the customer for their review – all within the portal system. I don't know if this exists or not. Does anyone know if there's a portal or CRM system that offers this sort of functionality? Could this type of system be custom built by a developer? Any/all help is appreciated.
