Start on one, expand later

Selling everywhere on day one splits your focus, inventory, and data across channels that each need mastering, so you end up mediocre on all of them. Pick one, get it working, then expand on clear signals.

New sellers list on Amazon, Etsy, eBay, and a store at once, thinking wider reach means more sales, then run out of stock when one listing pops and never learn which channel actually fit. Depth on one channel beats presence on five: you learn what sells and at what margin, and build one repeatable acquisition motion. Add channel #2 only when the first is stable and a real readiness signal appears, with inventory sync and consistent pricing in place first.
