Marketplace & direct-to-consumer

E-Commerce Seller

Inventory is a bet you make with your own money.

Typical pay

$0-$150k+, extremely variable

How you get in

None — product and margin discipline

Outlook

Crowded; brand and differentiation are what survive

E-commerce sellers source and sell products online through marketplaces or their own storefronts. The barrier to entry is near zero and the failure rate is high — cash tied up in inventory that will not sell is how most of it ends.
