A brief of idea
While the barriers to entry for a retail shop can be very high, one way to keep costs down and limit your time investment while you keep your full-time job, is to set up a weekend popup shop as a side business idea. More of whatever it is you’re selling—donuts, clothing, antique baseball cards, or anything else—will stay in your pockets instead of going to pay for operating expenses such as rent or utilities by choosing to pursue retail as a side business idea with a short-term rental.
