Everything you need to run your reselling business

Built for resellers who are serious about profit

ResellIQ isn't a generic inventory tool with a reseller skin on top. Every feature was designed around the actual workflow of someone buying, tracking, listing, and selling across multiple platforms — because that's exactly how we built it.

The problem

Reselling is a real business. Most tools don't treat it like one.

The average active reseller uses a notes app, a spreadsheet, their email inbox, a calculator, and a browser tab of eBay sold listings — and somehow tries to hold the whole business together in their head. Something always falls through.

Inventory

Every item. Every stage. One place.

Most resellers juggle a notes app for purchases, a spreadsheet for prices, and their memory for everything else. That's fine when you're moving five items a week. When you're running a real business — buying at Whatnot auctions, sourcing charity shops, flipping on four platforms simultaneously — it falls apart fast.

ResellIQ gives every item a home the moment you buy it. Log a purchase in under a minute: name, price paid, condition, photos. The item tracks itself from Ordered → In Transit → Arrived → Listed → Sold, with profit calculated at every step. Nothing slips through.

  • Full lifecycle tracking from purchase to final sale
  • Real-time profit calculation at every status
  • Photo management with drag-to-reorder
  • Filter, search, and sort across your full catalogue
  • Works for clothing, sneakers, Pokémon cards, and more

AI Scanner

One photo. Full listing.

Photographing an item is step one of listing it. But then you're manually typing the brand, guessing the condition grade, picking a category, comparing active listings to price it. For one item that's fine. For a haul of 30 it's an hour of admin you didn't sign up for.

Point your camera at any clothing item and ResellIQ's AI — powered by GPT-4o vision — returns the brand, exact style name, condition grade, colour, material, size, and a suggested resale price range based on live eBay active listings. All in under 10 seconds. Everything lands directly in your add-item form ready to review and save.

  • Identifies brand from partial logos, labels, and garment cut
  • Grades condition honestly — new with tags to fair
  • Compares live eBay active listings for the exact item
  • Detects style, material, and key features automatically
  • Flags authenticity concerns where visible

AI Descriptions

Platform-perfect listing copy in one click.

Writing a listing description is one of those tasks that sounds quick but eats 10 minutes per item. And the description that works on eBay — keyword-dense, spec-heavy — is completely wrong for Depop, where punchy vibes sell, or Vinted, where honest and conversational wins.

ResellIQ generates four separate, platform-optimised descriptions in a single click: eBay copy that ranks in search and converts detail-oriented buyers; Vinted copy that builds trust through honesty; Depop copy that stops the scroll with the right aesthetic energy; Poshmark copy that sells the lifestyle, not just the garment. Preview each one, copy, or drop it straight into your description field.

  • eBay: SEO-keyword-rich with spec bullet points
  • Vinted: conversational, transparent, community-toned
  • Depop: punchy Gen-Z aesthetic, under 55 words
  • Poshmark: aspirational, styling-led, lifestyle-focused
  • Available on both add-item and edit-item forms

Market Data

Price it right the first time.

Pricing by gut feel means you'll either leave money on the table or overprice and sit on stock for weeks. The honest way to price secondhand items is checking what similar items are actively listed for right now.

ResellIQ pulls live eBay active listings for every item you add, strips outliers, and gives you a low/average/high range of what the market currently looks like. The AI scanner enriches this with model-specific data — so you're not just looking at 'Nike hoodie' prices, you're looking at active listings for that exact colourway and model. Refresh any item's market price at any time.

  • Live eBay active listing prices integrated into every item scan
  • Low / average / high range from current market listings
  • Outlier trimming for accurate averages
  • Refresh market price for any existing item
  • UK/GB marketplace data by default

Email Action Cards

Your inbox becomes a control panel.

Every sale on eBay, every Whatnot order confirmation, every dispatch notification — it all lands in your email and gets ignored until something goes wrong. Manually reconciling email confirmations with your inventory is the kind of soul-destroying admin that makes people quit reselling.

Connect your Gmail and ResellIQ reads your reseller emails automatically. New eBay order? Action card created. Item ready to dispatch? Card appears. Sale confirmed? Profit logged. You act directly from the card — mark arrived, mark dispatched, add tracking — without ever opening a spreadsheet or digging through threads.

  • Gmail OAuth integration — read-only, privacy-safe
  • Auto-detects eBay, Whatnot, Etsy, and Depop emails
  • Action cards for: new orders, dispatch prompts, sale confirmations
  • One-click actions: mark arrived, add tracking, confirm sale
  • Full email thread accessible from each card

Expenses

See your actual profit, not just your revenue.

Every reseller knows their sell price. Almost none of them know their true margin. Packaging, postage labels, platform fees, mileage to the charity shop, a new rail, a steamer — it all adds up and it all erodes your profit in ways that are invisible if you're not tracking.

ResellIQ's expense tracker lets you log every business cost — one-off or recurring — and attributes them to your overall profitability. The analytics dashboard then shows your real net profit against total revenue, so you know whether that Whatnot haul actually made you money after fees and packaging.

  • Log any expense: packaging, fees, travel, equipment
  • Tag expenses by category for visibility
  • Recurring expense support for subscriptions and overheads
  • Net profit calculation across your full business
  • Cash flow timeline view month by month

Analytics

Know what's actually working.

Busy and profitable are not the same thing. You can be moving 20 items a week and still be losing money if your sourcing is wrong, your fees are eating your margin, or you're holding stock too long. Without data you're flying blind.

The ResellIQ analytics dashboard shows you profit over time, ROI by sourcing platform, average days to sell by category, your best and worst performing item types, and cash flow trends. It answers the questions that actually drive a reselling business: what should I buy more of, where should I source, which platform should I focus on.

  • Profit and revenue charts over any time period
  • ROI breakdown by source platform
  • Average sell time by category
  • Best-performing brands and item types
  • Month-on-month cash flow comparison

Pokémon Deal Scanner

Find underpriced cards before anyone else.

Pokémon card arbitrage is a real business — but it requires scanning hundreds of live listings, comparing each against current market prices, calculating fees and shipping, and acting fast. Doing that manually is a full-time job. Most resellers either guess or miss deals entirely.

ResellIQ's Pokémon scanner monitors live eBay listings in real time, cross-references every card against current active listing prices, strips out raw deals that won't grade, and surfaces only the listings where the margin genuinely makes sense. You see buy price, market value, estimated profit, confidence score, and ROI — then buy directly from the card.

  • Monitors thousands of live eBay listings continuously
  • Live eBay price comparison per card
  • Min margin and min profit thresholds you control
  • Confidence scoring based on listing volume
  • Stream companion for live Whatnot buying decisions

Why we built it

We resell too

ResellIQ was built out of the frustration of running an actual reselling business. We know what it's like to buy a haul on Whatnot at midnight, not know if you got a good deal until you check eBay prices the next morning, then spend an hour manually logging everything into a spreadsheet you'll probably forget to update.

We know the feeling of a sale arriving in your inbox that you have no record of. We've underpriced items because we didn't check active prices. We've lost track of what we paid for something. We've written the same listing description five times across five platforms with slightly different wording each time.

ResellIQ exists because none of the tools we tried were built for this specific workflow. They were either too generic, too expensive, too complex to set up, or missing the one thing that would have made them actually useful — like live market data, or an AI that understands what a Carhartt WIP jacket is worth.

Every feature in ResellIQ is the direct answer to a specific problem we ran into. The AI scanner exists because photographing and typing item details is the most boring part of the job. The email action cards exist because we missed a dispatch deadline. The Pokémon deal scanner exists because manually checking prices on a live Whatnot stream is impossible.

We built the tool we wished we had. We'd love you to use it.
