manually onboarding your early b2b customers is sooooo worth the time.
you get to explain the product in the context of their actual business, help them get something working, and see exactly where they get confused. a question you answer on a call might explain why ten other people signed up and never came back.
the customer gets someone who understands what they're trying to do and is invested in making it work. that feels pretty different from being sent a help article after paying. you're building a relationship they can come back to when something breaks or their needs change.
and you're learning how to sell it better, too. you hear the words they use, what finally makes it click, and which parts they actually care about. all of that should make its way back into the product.
