Stock Gap Fulfilment: How Online Retailers Stop Losing Sales to Sell-Outs

How online retailers recover full-price sales lost to sell-outs by routing out-of-stock orders to verified supplier stock, without buying more inventory.

Stock gap fulfilment for online retailers

Every online retailer knows the feeling: a customer finds the exact product they want, picks their size, and it is sold out. That sale usually walks to a competitor. Across a full assortment, sell-outs quietly cost retailers a large share of full-price revenue.

Stock gap fulfilment fixes this without buying more inventory.

What stock gap fulfilment is

When a size or product sells out on your site, the listing stays live. If a customer orders it, the order is routed to a verified supplier or the brand itself, who holds the same item and ships it directly to your customer. You keep the sale, the customer and the margin.

Why sell-outs are so costly

Full-price sales are lost, not discounted ones. Sell-outs hit your best-selling items first.
Customers switch sites and may not come back.
Buying deeper is risky, because over-buying creates markdowns later.

How it works in practice

You share your catalog and stock levels.
Stock held by verified suppliers and brands is matched to your out-of-stock items, size by size.
When a customer orders a sold-out size, the order routes to the matched stock.
The supplier ships direct to your customer, and tracking flows back to you.
You settle after your customer has paid.

What to look for in a partner

Verified, authentic supply from official channels.
Exact product matching at size and colour level.
Reliable, tracked shipping in your customer's market.
Brand rules respected, so the brand is comfortable with the setup.
