Free eBay Reseller Tools
These free tools are for eBay resellers who buy items to flip — at thrift stores, estate sales, garage sales, or online — and want a fast way to check whether an item is worth the risk before they buy it.
Each tool answers a different question. FlipCheck checks demand and competition using real eBay sold data. The eBay Profit Calculator estimates your profit after fees and shipping. The eBay Buy or Pass Checklist walks through the sourcing decision step by step so nothing gets missed.
If you are new to reselling, start with FlipCheck. It checks sold comps and competition first, so you know whether an item sells at all before spending time calculating profit on it.
