Auto-sort collections. Upsell smarter. Sell more.

QSortby keeps every collection in the order you choose: best-selling, trending, newest, most profitable, or your own formula, based on the last hour or the last month, and re-sorted on your schedule. Sold-out products move to the end and come back when restocked. Goes with keeps products that sell together side by side, and pairings can take turns. Each shopper group can get its own order, with every position explained. The same ranking fills cart, bought-together, popup, and checkout offers.
