If you do it yourself, what happens if you are the problem? And don’t say that you are never the problem because even the nicest, most personable person in the world has people that don’t like him.
Customer service is the activity of making sure a customer is happy with what they are getting. It is how customers are retained, accounts are grown and careers are made. Believing that you can handle the customer service and the workload is a fool’s errand. Everything may turn out fine most times but occasionally there will be that person that you just can’t get along with and you have no idea they aren’t happy.
Make sure you think about customer service in what you do. Give every client an outside escalation point that they can call when they feel shorted. Not for nothing – it’s great marketing because how many of your competitors are doing it?
