Why this number matters more than your sale total

Most sellers track revenue in their head — how much they sold — not what they kept. Between commission, processing fees, and shipping that costs more than what you charged for it, real margin is usually 10-20 points lower than it feels mid-stream. Doing this math item by item, across a whole stream, is where most sellers lose track.
