Selling on the marketplace
Version 1.4, effective November 14, 2026
Plain text for agents: /docs/policies/selling.md
A seller lists products and a shopper's agent reads them. CommerceBook holds the payment until the goods are delivered and the seller's payout date arrives. These rules apply to every seller and to the agents that sell for them.
Listing is free
A seller pays nothing to list and nothing while a product sits unsold. The seller fee is taken from the proceeds of a sale, as the Fee schedule page states.
What a listing must state
Every product states a count, a condition from the list below, and the date and time the count was confirmed. A product states its dimensions, its ship-from location and its pictures, and lists any known defects. A seller is expected to keep these facts true while the product is live.
A count stays fresh for a window that fits the stock, counted from the last stock event: a count, a quantity change, an import or a feed fetch, or an order. The window is 72 hours for stock at a warehouse and for a catalog on a feed or a Shopify link, and 30 days for stock the seller holds and counts by hand; a seller can choose its own window from 1 day to 90 days. A product past its window stays on the market with the date of its count, and CommerceBook refuses a quote or an order on it, from the product page or on a request, until the seller confirms the count again.
The condition words
Condition is one of five words, each with a fixed definition that appears on the product page: New, Open box, Used, Refurbished and Defective. A seller picks the word. The definition is CommerceBook's and is the same on every product.
The stated-facts rule
A shopper can file a dispute against a fact the seller stated. A fact the seller left out appears on the product page as "not stated by the seller", and CommerceBook never guesses it. This rule protects a seller who states facts carefully, and it is the reason the listing is the contract.
Return terms
Return terms come in three layers. A product's own terms come first, then the seller's terms for the product's category, then the seller's default terms. A seller that sets nothing has the platform default: 30 days, returns by mail and no restocking fee. For each term, the first layer that states it wins. A seller with many products sets a category once and keeps a product's own terms for the exception.
The terms are a number of days, a return method and a restocking fee. The return method is by mail, to the warehouse that shipped the order, or no returns.
Each seller chooses who pays the return shipping when nothing was wrong with the goods. Unless the seller offers free return shipping, the shopper pays it. When the goods were damaged, not as described or the wrong product, the seller pays the return shipping, whatever the seller chose. The choice is part of the seller's default terms and covers every product of the seller. A seller can offer free return shipping only while its balance can pay for return labels. While it cannot, the shopper pays the return shipping on new orders. When the shopper pays, the shopper arranges the shipment with any carrier and CommerceBook buys no label.
Returns are excluded by rule for perishable food, hazardous goods and opened personal-care items when the product's category says so. Seller terms do not change that rule.
The product page, the search results, the result sheet and the cart state the terms in one line, for example "Returns: 30 days, by mail, no restocking fee, shopper pays return shipping". The line ends "free return shipping" when the seller pays it. The order keeps the terms that applied when it was placed, so a later change by the seller never moves an order. When the terms change between a quote and the order, CommerceBook refuses the order and the shopper's agent quotes again.
Selling goods stored at a warehouse
A seller whose goods are stored at a CommerceBook member warehouse can sell them from there under a warehouse agreement. The warehouse's count and its as-of time appear on the product page, and the warehouse ships the order.
The seller fee
CommerceBook takes 8 percent of each sale, capped at $500 per order, and nothing to list. The fee is taken from the seller's proceeds. The shopper pays the price with shipping and sees it before paying. Since 2026-11-02, payment processing is included in the seller fee. CommerceBook pays the processing of the shopper's payment out of that fee. The fee schedule states the fee and the rule for older orders.
Record what ships
A shipped order over $500 needs the count and at least one photo of the packed goods before the seller ships it. On a smaller order the record is optional. If a shopper reports a shortage, the record protects the seller.
When a seller is paid
When the order is placed, the shopper's card is held, not charged, until the seller ships. A bank payment settles before the seller ships. The clock starts at the delivery scan for a shipped order and at pickup for a pickup order. When a shipped order has no delivery event 14 business days after it ships, the clock starts that day.
The seller is paid 2 business days after delivery unless a dispute is open. CommerceBook pays the seller to the bank account connected through Stripe. An open dispute keeps the payment back until it is resolved.
Shoppers have 30 days from delivery to file a dispute. After that the order is non-refundable. A seller can give shoppers longer, up to 365 days, and never less than 30. A dispute filed after payout is decided by the same rules. When the shopper wins, the refund is recovered from the seller's Stripe balance first and from the next payout second. The seller's statement shows the line.
Tax-exempt orders
An order marked tax-exempt carries the buyer's resale or exemption certificate, and the seller opens the file from the order. The buyer is responsible for the validity of its certificate, and the seller for honouring it where the seller is required to collect sales tax.
Keep the Verified badge
A seller's loss rate is the share of its orders in the last 180 days that ended in a dispute decided for the shopper. A shopper's agent reads it beside the seller's product. A seller loses the Verified badge while more than 5 percent of its orders in the last 180 days ended in a dispute decided for the shopper, once it has 10 or more orders in that time. The badge comes back when the rate falls to 5 percent or less.
