Part Signal: eBay Active & Sold Counter

A clean manual counter for active and sold listings, price ranges, STR, and work sessions.

Comp Count Pro is a manual research and workflow tool built for counting eBay active and sold listings. Add multiple items, select the item you are currently researching, and use the A and S buttons or keyboard shortcuts to update Active and Sold counts while browsing eBay. The extension automatically calculates sell-through rate and lets you record a price range for each item. A built-in work-session timer records your start time, pauses, breaks, end time, and total time worked. Your items and counts are able to be saved, and completed research can be exported in a simple format that opens in notepad. Comp Count Pro does not automatically scrape or count listings; it helps organize and speed up accurate manual research.
