7 Best Reselling Tools for UK Sellers in 2026

Profit Prophet

Free (3 scans/day) • Pro: £10.99/month (unlimited scans)

Point your camera at any item and get instant eBay sold prices, profit margins, and competition data. The AI identifies the item, pulls recently sold listings, and tells you what it's realistically worth. Generates eBay listings in seconds. Built in the UK, defaults to eBay UK pricing in pounds.

What makes it different: unlimited scans on Pro (most competitors cap you at 30-75/month), AI chat to ask follow-up questions about items, and built-in local sourcing to find charity shops and car boots near you.

Best for: car boot sellers, charity shop flippers, anyone who scans more than 30 items a month.

eBay

Free (selling fees apply)

The eBay app is still the single most important tool in a UK reseller's kit. The sold listings filter (Search → Filter → Sold Items) shows you real transaction prices for the last 90 days. If you're not checking this before pricing, you're guessing.

The app also handles listing creation, shipping labels (via Packlink or Evri integration), and messaging buyers. It's clunky, but it's where the money is.

Best for: everyone. This is non-negotiable.

Google Lens

Free

Point your camera at something and Google tells you what it is. It won't give you sold prices or profit margins, but it's the fastest way to identify an unknown item for free. Useful when you've found something you can't quite place - a piece of pottery, an unusual gadget, a vintage toy.

The limitation: it identifies but doesn't price. You'll still need to manually search eBay sold listings afterward. An AI scanner like Profit Prophet combines both steps into one.

Best for: identification only, when you don't have a pricing tool handy.

Royal Mail Click & Drop / Evri (formerly Hermes)

Pay per parcel

Royal Mail's Click & Drop lets you print shipping labels from home. Evri is usually cheaper for parcels under 2kg. Most UK resellers use both depending on the item size and weight. eBay's integrated shipping through Packlink often gives competitive rates too.

Tip: weigh and measure your items before listing so you can factor shipping into your pricing. A £5 profit disappears fast when postage costs £4.50.

Best for: every UK reseller shipping items.

Profit Prophet inventory / Google Sheets

Included in Profit Prophet / Free

Track what you bought, what you paid, what you sold it for, and your profit per item. Profit Prophet has a built-in inventory system with tags, profit tracking, and sale confirmation. If you prefer a spreadsheet, Google Sheets works fine - just make sure you track purchase price, selling price, platform fees, and shipping costs per item.

The resellers who know their numbers make money. The ones who don't think they're making money until they add up the fees.

Best for: anyone selling more than a few items a month.

Facebook Marketplace

Free (no selling fees for local collection)

For items that are too heavy or bulky to post, Facebook Marketplace is ideal. No selling fees, instant local audience, and you can list in under a minute. Furniture, large electronics, and bulky sports equipment all do well here.

The downside is dealing with no-shows and lowballers. Price 10-15% above what you'll accept and expect to negotiate.

Best for: large items, local-only sales, zero-fee selling.

Vinted

Free to list (buyer pays fees)

Vinted has exploded in the UK. If you're sourcing clothing, shoes, or accessories, it's worth listing there alongside eBay. The buyer pays the fees, so your margins are better than eBay for clothing. The audience is huge and actively looking for secondhand fashion.

Best for: clothing resellers, fashion flippers.
