How Whatnot Works, and What It Actually Costs
Whatnot is a live auction app. Sellers run a video stream, hold items up to the camera, and buyers bid in real time in a chat beside the video. When the timer on an item ends, the highest bidder has bought it, payment is taken inside the app, and the seller ships it. That is the whole mechanic, and it is genuinely different from a listing marketplace, where you photograph something, write it up, and wait.
This page covers how a show actually runs, what the platform takes, and where the format helps you and where it does not.
How a show runs
A seller schedules a show, and buyers who follow them get a notification when it starts. During the stream the seller works through items one at a time. Each item gets a starting price and a short countdown, usually measured in seconds rather than days, and every new bid extends the clock slightly so the auction cannot be won by sniping in the final instant.
Buyers ask questions in the chat while an item is being shown, and the seller answers by moving the item rather than typing: turning it over, holding a mark to the lens, pointing a light at a stone. That exchange is the actual product. It is why the format works for goods whose condition carries the value and why it adds nothing for goods that are identical to every other unit of themselves.
Shipping is arranged through the app. Multiple wins from the same seller in the same show are usually combined into one parcel, which is one of the format's quiet advantages over buying four things from four listings.
What Whatnot charges the seller
Two separate charges, and comparisons often quote only the first.
| What | Rate |
|---|---|
| Commission, most categories | 8% |
| Payment processing | 2.9% + $0.30, charged on the total order including shipping and tax |
Read from Whatnot's own published seller fees page on 27 August 2026. The processing charge is the one that surprises people, because it applies to the whole order value rather than the item price, so shipping you collected from the buyer is also charged.
On a $100 item with $10 shipping, the seller pays $8.00 commission plus $3.49 processing, so $11.49 in total. On a $1,000 item the same math gives roughly $109.
What the format is good at, honestly
Goods that photograph badly and demonstrate well. A stone that has to move in the light, a flaw that needs context, a card whose corners a buyer wants to see from an angle. These sell for more when they can be shown and questioned.
Selling volume in one sitting. A seller can move fifty items in ninety minutes. A listing marketplace would take fifty separate photographs, descriptions and dispatches.
Building repeat buyers. People come back to a person rather than a search result, which is the part sellers underestimate before they try it.
What it is not good at
Standardized goods. If an item is identical to every other one, there is nothing to demonstrate, and a search-based marketplace where buyers compare on price serves it better.
Anything you are not ready to answer for. The format rewards being able to show the thing. A seller who is evasive under a direct question is exposed on camera in a way a listing never exposes them.
Selling while you sleep. Listings work without you. A live show does not exist unless you are running it.
Where ShopBidz comes in
ShopBidz runs the same format, and the rate is the plain difference: 8.8 percent from the seller, card processing included, with buyers paying 30 cents per charge.
Against Whatnot's 8 percent plus 2.9 percent on the whole order, that is a real gap. On a $100 sale with no shipping it is $11.20 against $8.80. On the $1,000 sale it is roughly $109 against $88.
The honest cost is audience. Whatnot has years of buyers and a scale ShopBidz does not have, and a higher rate on a sale that happens beats a lower rate on one that does not. If you already have a following on Whatnot, the fee is not the argument for moving. If you are starting cold on either, you are choosing between two audiences you do not yet have, and then the rate is most of the decision.
Most sellers who take live selling seriously end up running more than one channel, for the same reason they always have: no marketplace lets you control its fees, its policies or its algorithm.
