A no-nonsense breakdown of the best tools for eBay resellers — from finding stock to tracking profit. Includes free and paid options for every stage of the reselling process.
Reselling on eBay is more competitive than ever. The sellers making consistent profit aren't just finding better stock — they're using better tools. Here's a breakdown of the best tools at every stage of the reselling process.
The best resellers source from auctions, not retail arbitrage. Auction lots regularly sell for 10–30% of their market value — but you need to find them fast before anyone else does.
Arbitrage AI is built specifically for this. It scans auction houses for lots ending soon, gives each one an AI score for resale potential, and shows you the eBay median sell price alongside a calculated max bid. It's the only pre-purchase intelligence tool on the market.

Other sourcing options:
The biggest mistake new resellers make is guessing. Before you buy anything, you need to know what it actually sells for — not what people are asking for it.
eBay completed listings — filter by "Sold items" on eBay to see actual sale prices, not just asking prices. This is the gold standard for pricing research.
Arbitrage AI price intel — automatically pulls eBay median sold prices for any lot title and compares across platforms including Depop, Vinted and Etsy so you know where to list for maximum return.
WhatNotSold — useful for checking sneaker and streetwear prices specifically.
The faster you list, the faster you get paid. These tools speed up the process:
Most resellers have no idea if they're profitable after fees, postage, packaging and time. Proper tracking changes that.
Arbitrage AI profit tracker — log every won lot, record sell price, and see your real P&L after all fees and expenses. Also flags your "death pile" — items that haven't sold in 30+ days that are tying up your capital.
A spreadsheet — free, flexible, but time-consuming. Worth starting with before investing in paid tools.
Seller Hub (eBay) — eBay's free dashboard shows revenue and basic metrics, but doesn't account for sourcing costs.
Once you're turning over more than a few hundred pounds a month, you need to track this properly.
For most eBay resellers starting out, you don't need ten different tools. This covers everything:
| Stage | Tool | Cost | |-------|------|------| | Find stock | Arbitrage AI | £9.99/mo | | Price research | Arbitrage AI + eBay sold | Included | | List items | eBay Seller Hub | Free | | Track profit | Arbitrage AI | Included | | Tax records | CSV export | Included |
One subscription covers sourcing, pricing and profit tracking — which is exactly why we built it that way.
