Doing business

OPEN

Think of the word stores use when they're ready to welcome customers at the start of the day.

The clue "Doing business" hints at a store or shop being active and ready for customers. In everyday language, when a business is "open," it means it’s operating and available for transactions. The answer plays on the double meaning of "open"—both literally (doors unlocked) and figuratively (conducting business). It’s a straightforward definition with no hidden wordplay, just a common phrase tied to commerce.
