Definition
Customer service is the support provided to customers before, during, and after purchase. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.
In the room
How the word shows up in a real conversation.
A mentor asks, “What is your Customer service?” The useful answer is concrete: support provided to customers before, during, and after purchase. A slide title is not an answer.
Common mistake
Using Customer service as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
