The Buy Box is the "Add to basket" position on an Amazon product page. When several sellers offer the same product, Amazon awards that button to one of them, and the overwhelming majority of sales on that listing go to whoever holds it. If you do not have the Buy Box, you are effectively invisible, no matter how good your listing is.
This report tells you how often your mapped products actually held it. It is one of the four views on the Analytics screen, and like the rest of Analytics it is available on Growth and above.
This is the one thing to understand before you read anything else on this page.
Buy Box results are recorded on each price sync of a mapped product. Every time the app checks a product's price on Amazon, it also records whether you held the Buy Box at that moment. The report is built from those stored readings.
Three consequences follow, and all three surprise people:
History has to build up. The app cannot ask Amazon what your Buy Box status was last Tuesday, because Amazon does not offer that. It can only record what it sees, when it looks. A store that has just installed the app has no history yet, and the report will legitimately say "No Buy Box data yet". Nothing is broken. Come back in a few days.
Your plan's sync interval sets the resolution. Each sync is one data point per product. The more often your plan syncs, the finer grained the picture. On the Free plan, syncing every 24 hours, you get roughly one reading per product per day, enough to see a trend but not enough to catch a competitor who undercuts you for a few hours each evening. The paid plans sync every 6 hours, and Full can buy a faster tier as an add-on. See Plans and billing.
Only mapped products appear. A product has to be linked to an ASIN on the Product Mapping page for the app to be checking it at all.
Choose the window the report covers: 7 days, 30 days (the default), 90 days, 12 months, or all time. Selecting a longer period than you have history for is harmless. It simply shows you everything you have.
Use 7 days when you have just made a pricing change and want to see whether it worked. Use 30 or 90 days to judge whether a product is genuinely competitive rather than having a good week.
Overall win rate is the headline percentage: across every reading taken in the period, on every mapped product, the share where you held the Buy Box.
The data-point count sits alongside it, and it is there to keep you honest. A 100% win rate from 4 readings is not a fact about your business, it is a small sample. A 68% win rate from 3,000 readings is worth acting on. Always read the win rate and the count together.
The daily trend plots the win rate over the period, so you can see direction rather than a single number. This is where a competitor arriving, or a repricer change taking effect, actually becomes visible.
Below that, each mapped product carries a badge:
A low win rate is a diagnosis, not a verdict. Work through it in this order.
Check for No offer rows first. If a chunk of your catalogue is showing No offer, your win rate is being dragged down by products that are not even competing. Fix availability and suppression before you touch a single price.
Then look at price. Amazon weighs several factors, but on most listings, against most competitors, price is what moves it. If you are consistently Not winning on a product where you are in stock and shipping promptly, you are very likely priced above the competing offer.
Then decide whether the Buy Box is worth what it would cost you. Winning it on a product whose margin is already thin can mean selling more units for less profit than you make today. Open the Margin report alongside this one before you cut a price. A product that is Not winning but comfortably profitable may be exactly where you want it.
If you want the Buy Box on a product and you are prepared to price for it, that is what the Repricer is for. It checks the competing offers and adjusts your Amazon price within a floor and a ceiling that you set, so you compete without being dragged below a price you are willing to sell at. Crucially, when you already hold the Buy Box, it holds your price rather than cutting it further.
The Repricer is available on Growth and above, and it only reprices products you have published through Product Sync.
After you turn it on or change its rules, come back to this report in a few days and read the daily trend. That is the honest measure of whether it is working.
Note
The Buy Box percentage tile on the Dashboard is a snapshot of your most recent readings. This report is the history. If the two disagree, the Dashboard is telling you about now and the report is telling you about the period you selected.
Export CSV downloads the report as it stands for the selected period, so you can chart the trend yourself or cross-reference it against your own sales data.
