The cost of waiting

Your customers are already reselling you.

Most of that demand replaces a first-hand purchase you’ll never make — on marketplaces that keep the buyer, the data and the margin. Running resale yourself is how you take all three back.

2/3 of resale purchases replace a first-hand sale
46% won't buy new if they can find it secondhand
70% of secondhand buyers are new to the brand

How it works · recommerce

Trade-in, end to end.

You take the item back, grade it, and resell it. Zelph runs the workflow and the channels — your 3PL handles the items.
