I suggest you don't say that at all because it's ungrammatical. If the phrase is used at all, it should be "What is it regarding, please?" But it sounds stilted and unnatural.
"Good morning/afternoon. How may I help you?"
"Good morning/afternoon. What can I do for you?"
"Good morning/afternoon. How can I be of assistance?"
"Hello. Can I help you?"
