FlipSumo

In the world of reselling, speed is everything. The best deals on Facebook Marketplace, Craigslist, OfferUp, and eBay are gone within minutes, often snapped up before most buyers even see the listing. FlipSumo was built to solve exactly that problem.

FlipSumo is a real-time marketplace alert platform that monitors your favorite buying platforms simultaneously and notifies you the moment a matching listing goes live, typically within 60 seconds of it being posted. That's hours faster than Facebook's own built-in notifications, which routinely lag 2 to 6 hours behind. With FlipSumo, you're messaging sellers while your competition is still scrolling.

• Set It Once, Source Continuously

Instead of spending hours manually checking multiple apps and websites, you simply set up a watchlist with your keywords, price range, location radius, and preferred platforms, and FlipSumo does the hunting for you. Add negative keywords and price caps to filter out the noise, and over time your deal feed gets sharper and more relevant. Whether you're flipping sneakers, electronics, furniture, vehicles, or anything in between, FlipSumo keeps your pipeline full without the manual grind.

*Works Where You Already Are

FlipSumo pushes alerts directly into Discord, Telegram, SMS, or email, wherever you already spend your time. No new interface to learn, no extra app to check. Just instant notifications landing in your existing workflow so you can act fast without breaking your rhythm.

• Built for Every Level of Reseller

FlipSumo's flexible, slot-based pricing means you only pay for what you use and can scale up or down as your sourcing needs change. The Basic plan scans every 5 minutes at $5/month per watchlist slot, already faster than many competitors' 10-minute tiers. The Premium plan bumps that up to 1-minute scan intervals for $9/month per slot, giving you the fastest possible edge in high-turnover niches like electronics and sneakers.

• Total Market Visibility FlipSumo monitors Facebook Marketplace, Craigslist, OfferUp, eBay, Kijiji, Gumtree, Nextdoor, and more, with new platforms being added regularly. Running multiple watchlists at the same time means you have eyes across your entire market at once, giving you a real advantage over local dealers and independent buyers who are only checking one platform.
