Depends on the business. If it's cupcakes, I say go for it...ASAP!
I'm involved in what was a small brick and mortar cupcake operation. We started about 18 months ago and have been growing ever since. Last Saturday night we sold 996 cupcakes at $3.50 each. Not a bad night
We're about to open a 2nd location, new production facility and delivery business. I don't think we're all that small anymore.
