Flex is a programme for Sellers to store, list and sell pre-verified items with StockX. This programme is open to all L2+ Sellers in selected regions who have agreed to the Flex Terms of Service. Buyers will see these items listed as Xpress Ship or with a rocket icon next to the product on the StockX website or app.

Sellers in Flex can send eligible items to StockX’s Verification Centres and authorised warehouses, where they are verified and securely held in inventory. As soon as a Flex Ask matches with a Buyer and an order is placed, StockX will despatch the item from Flex inventory, directly to the Buyer. To learn more about Xpress Ship, visit our article here.

To get started, navigate to StockX Pro and open the Flex Inbound Lists tab. To move your items into Flex, click on the green button at the top that says "Send Items to Flex". This button also appears under Flex in the Inventory Tab.

If you click on the search area, you'll see a suggested list of SKUs. You won't be able to select some of them because they're not eligible for Flex. Those that you are able to select are eligible.

Click an eligible item and you'll see a list of sizes. You can select the sizes you want to send, up to a maximum of 16 pairs of trainers per box. Please attach the correct shipping label to the box that corresponds to the manifest you created. This is essential to avoid intake issues.

The table below displays the fees for each eligible Seller level, as well as the discounts for meeting certain criteria. The item days-in-storage count begins as soon as the item is available for listing on StockX via Flex. Flex Sellers will receive an Inventory Storage Invoice on the 1st of each month, with the fees charged on the 15th of each month.

Brands in the following categories can be sold on Flex. Bear in mind that some bulky items such as rugs, chairs and other types of furniture may not be eligible:

Flex items are subject to our proprietary, multi-step verification process from our team of Verification Experts. With Flex, when you send your item to StockX, we verify and add it to our inventory. When the pre-verified item is sold, we ship it to the Buyer straightaway.

There is a $5/item fee for Sellers in the US, €5/item for Sellers in Europe, £5/item fee for Sellers in the UK and $40 HKD/item for Sellers in Hong Kong to return an item out of Flex inventory. StockX will send your item back to the shipping address in your account.

If your item or items are sold, you will receive your payout, subject to any and all applicable fees and taxes. Since your items are already verified once they sell, you'll get paid the day we process your order with Scheduled Payouts. Read more about Scheduled Payouts here. StockX cannot guarantee that any of your items will be sold.

The average order value (AOV) of the goods over the most recent 30-day period on the StockX platform, plus 10%.

If the AOV is not available for such a 30-day period, StockX will use alternative calculations that most accurately reflect market valuation.
