Well, i feel a bit silly even asking this…
What is the name for a business that provides small businesses with customer services.
For example a 2 person company develops a reasonably popular app. They don't have the time to provide good customer service so they employ an external company to provide this for them.
What service would this be? I've searched; outsourced customer service, external customer service, and business support service so far but I'm not sure.
