How do you sell to clients?

Hey guys I'm back,

I had a post here a few days ago talking about my agent marketplace app/website

I'm wondering how you all manage your agents once you have sold them. Do you set it up for the client, then dish it off to them? Or do you set it up for them and run it independently on your side? I'm sure there are many different ways, but any input helps!

Also, if you are interested in this project, send me a message!

Thanks.
