Competitive intelligence built for solo eBay sellers
A rival can undercut your Buy It Now price or sell through their last unit between one morning and the next. Shelfhawk checks the eBay listings you compete with for price and stock through eBay’s official API — once or twice a day, depending on your plan — and emails you a plain-English briefing of what moved.
Three jobs Shelfhawk takes off your plate.
Every price change on a tracked eBay listing is logged with the old price, the new price and the difference, and lands in your next briefing. Turn on an instant alert for the few listings that matter most.
When a rival sells their last unit or the listing ends, the next scheduled check flags it — that is your window to win the sale, and it shows up in your alerts and your next briefing.
Enter what a unit costs you and every rival price shows the margin you’d keep if you matched it — green for healthy, amber for thin, red for a loss — before you touch your own price.
What shows up in your daily briefing
Price, stock and margin, in one plain-English email.
A condensed sample with fictional rivals. Your briefing arrives at the time you choose and covers what changed since the last one — every entry tone-tagged so you see the threat level before you read the detail.
Sample briefing · eBay
A 9.7% undercut on a Buy It Now listing you compete with. Match it and you’d keep a 12% margin at the cost you entered — thin, so worth a second look.
The second rival to cut on this item since your last briefing. Both prices are in the listing’s history so you can see the trend.
The last check found the listing gone. While it’s down, buyers have one fewer option — make sure your own listing is live and in stock.
Amber — thin. At the cost you entered, matching keeps you in profit, but only just. Shelfhawk never recommends a price below your cost.
