SellerEngine
SellerEngine makes software and services for Amazon sellers.
SellerEngine makes software and services for Amazon sellers. Its main products are Sellery, a real-time, rule-based Amazon repricer, BuyBoxBuddy, an algorithmic repricer aimed at winning the Buy Box, and Profit Bandit, a scouting app for web and mobile that scans barcodes or analyzes batches of products to estimate Amazon profit. Sellery reacts to competitor price changes as they happen, calculates a dynamic minimum price from cost of goods, shipping and fees, and supports rules based on Buy Box ownership, sales velocity for private label items and aged FBA inventory. SellerEngine also offers Amazon consulting services and publishes an Amazon news blog. All of its tools are for Amazon only. They do not work with eBay.

FAQ
Sellery charges 1% of your gross monthly sales, with a minimum of $50 per month and a maximum of $2,000 per month. SellerEngine says there are no contracts, commitments or hidden fees. A seller with $10,000 in monthly sales would pay about $100. You can start with a free two-week trial before any charges apply.
Yes. SellerEngine offers a free two-week trial of Sellery, its real-time Amazon repricer, with sign-up links on the Sellery product page. Profit Bandit is available through the Apple App Store and Google Play, where trial and subscription terms are shown in the store listing. Check the BuyBoxBuddy page for its own trial terms.
Log in to Sellery, open the Subscription tab and choose Cancel My Sellery Account. SellerEngine says this is the only authorized way to cancel. If you cancel before the end of a billing period, you are still billed for the full period, and your data may be deleted. Profit Bandit subscriptions bought in an app store are cancelled in your Apple or Google account.
No. Sellery, BuyBoxBuddy and Profit Bandit are all built for Amazon. They reprice Amazon listings, target the Amazon Buy Box and estimate Amazon profit when scouting products. SellerEngine does not list eBay support. eBay sellers who need repricing or sourcing tools must use separate software designed for eBay.
Sellery is a rule-based repricer where you set strategies, such as undercutting or matching competitors, acting differently when you own the Buy Box, or using sales velocity. BuyBoxBuddy is an algorithmic repricer with simpler settings that aims to increase Buy Box ownership and includes analytics. Both are Amazon-only and come from SellerEngine.
SellerEngine has a support site at support.sellerengine.com with help articles and videos for Sellery and Profit Bandit, plus a Sellery support form on its website. The company also offers consultations with Amazon experts and a Contact Us page. Its blog and monthly newsletter cover Amazon policy changes.
Other Amazon repricers include RepricerExpress, Aura, Informed Repricer, Seller Snap, BQool and Feedvisor. For product scouting, alternatives to Profit Bandit include the Amazon Seller app, Scoutify from InventoryLab and SellerAmp SAS. RepricerExpress prices by SKU count rather than a share of sales, which some high-volume sellers prefer.
