After working with a customer for about a week on an annoying PayDotCom issue we finally got it resolved. He sent me a nice email that really made my week-

Jason,

Thank you so much for all your help on this matter. You have gone above
and beyond call of duty. I will be sure to talk your delivery system up

Being a small company we can’t afford thousands of dollars worth of advertising, so it feels good when we make a customer happy when they come to us with problems. After all, word-of-mouth advertising is the best kind, and aside from talking to your customers and working out their issues you don’t even spend a penny on it.
