Not every customer has the same problem, the same opinion, or the same reason to buy from you.
But if they’re your customer, they’re yours to keep. Or to lose.
You lose a customer by taking their money, and moving on to the next customer. You lose a customer not through actively annoying them, but through neglect.
You keep a customer by listening. By seeking their feedback. By understanding them. And then by acting. By making your product or your service better for them based on their needs.
If you can keep that feedback loop frequent and efficient, it’s hard to go wrong.
Just don’t stop seeking feedback, and don’t start thinking you know better than your customer. They’re usually right.
