While you sleep, competitors cut their price and take the buy box. SellBox watches competitor prices 24/7 and alerts you the instant you lose it.
Grab your API key from your seller panel and connect in 5 minutes. No downloads, no setup, no developer required.
A pre-sale optimization platform built for marketplace sellers, starting with Trendyol. No updates to manage — even when the marketplace algorithm changes, you stay current automatically.
The instant a competitor changes price, you update too. Never let the buy box slip — keep the orders coming. Backed by AI-powered repricing that doesn't just copy the competitor, it recommends the most profitable strategy.
Commission, shipping, returns — see your true net profit before you set a price. Never sell at a loss again.
The moment a competitor runs out of stock, raise your price. Automatically move into the strongest position in the market.
Your entire store on one screen. Orders, profit, buy box rate — everything at a glance.
AI answers customer questions on the marketplace in seconds. Your response-time rating never drops, and you don't have to lift a finger.
Manage every return request from one panel. See which products get returned most often and factor return costs into your profit calculation.
"Before SellBox, I had no idea which of my products were losing money. In the first week I raised my margin by 5% — just by pricing correctly. Now I see the net profit of every product before I even list it."
"When a competitor sold out, the system automatically raised my price. I had a record profit day. There's no way I could have caught that manually — SellBox handles it now."
"AI answers customer questions, buy box tracking runs itself. I just focus on shipping. My monthly revenue doubled in the first three months."
Before SellBox, SAFA Books was getting just 4 orders a month. Prices were updated manually and competitor moves went unnoticed. With SellBox, they started holding the buy box consistently, cut the products that were dragging down margin, and grew order volume 50x.

The buy box is the system that decides which seller gets to show the "Add to Cart" button on a product page. Even when dozens of sellers list the same item, the vast majority of orders go to whoever holds the buy box. Price alone doesn't decide it — seller rating, shipping speed, and operational status matter too. SellBox analyzes all of these factors together so you can win the buy box while protecting your margin.
The buy box algorithm doesn't just look at price. Seller rating (staying above 9.0 is critical), operational status, shipping speed, and return rate all factor in. SellBox tracks every one of these signals and alerts you the instant you lose the buy box.
Rule-based repricers just copy the competitor — they cut price, win the buy box, and erode your margin along the way. SellBox uses real AI to analyze commission, shipping, and competitive dynamics together, recommending the price that wins the buy box and leaves you the highest possible profit.
No. Price wars erode your margin — your competitors do the same thing and everyone loses. SellBox calculates the highest price that can still win the buy box without dropping below the minimum margin you set. You stay in the buy box and stay profitable.
Yes. SellBox continuously monitors your competitors' price changes. The moment a competitor drops their price to win the buy box, or runs out of stock and opens up an opportunity for you, you get an alert. No manual tracking required.
Real net profit on a marketplace is complicated: commission (which varies by category), platform service fees, weight-based shipping cost, and tax all come out of the sale price. SellBox's profit calculator works out every one of these line items automatically, showing you exactly which products are actually profitable and which are quietly losing you money.
Our users typically see an increase in their buy box rate within the first week. With SellBox, sellers have grown order volume by up to 20x within three months.
