SellBox is a repricing and monitoring platform built so marketplace sellers can win the buy box without eroding profit. It tracks competitor prices, stock and seller ratings around the clock, factors in category commission and shipping cost, and never lets a pricing rule drop a product below its defined margin floor. It holds the buy box at the highest price that stays above that floor, raises the price back when a competitor runs out of stock and alerts within minutes when the buy box is lost.

Hey Product Hunt! 👋 We built SellBox after watching Trendyol sellers lose the buybox to competitors who simply raced prices to the bottom — and lost money doing it. Most repricing tools only optimize for "lowest price wins." But on Trendyol, winning the buybox at a price that erodes your margin isn't a win. So we built SellBox to calculate true net profit — commission, shipping costs, and tax all included — before it ever suggests a price change. It tracks competitor prices and stock around the clock, alerts you the second you lose the buybox, and helps you win it back without a race to the bottom. Would love your feedback — especially if you sell on Trendyol or any marketplace with similar buybox dynamics!
