Buyers can rate sellers on a 5 star scale across key dimensions. These dimensions are (1) Overall (2) Shipping (3) Packaging (4) Accuracy
The ratings you receive will appear across Whatnot and potential buyers will be able to see how you are rated across these dimensions. To maintain a high rating, it's important you ship things fast, package them well, and ensure you accurately describe items to buyers.
The rating you see on your profile is a blend of these ratings categories.
A buyer will only be able to rate a seller once their items are delivered, or if a seller cancels an order. If a buyer requests a cancellation, they will not be able to rate a seller even if the seller rejects the cancellation.
Below is what the ratings process looks like for buyers.
