About ResellAIO
The inventory and profit-tracking platform built by resellers, for resellers.
Why ResellAIO exists
ResellAIO started the way most reselling operations do: with a spreadsheet. Tracking sneakers, streetwear, and collectibles across eBay, StockX, Grailed, and Depop meant copying numbers between tabs, recalculating fees by hand for every platform, and never being quite sure whether a flip actually made money after fees, shipping, and currency conversion.
We built ResellAIO to answer one question accurately and automatically: is your reselling actually profitable? Every feature — fee-aware profit tracking, StockX market data, multi-currency support, expense tracking, aged-stock alerts — exists in service of that question.
The product is priced the way we wished tools were priced when we were starting out: one flat monthly rate, every feature included, no per-item or size-based tiers that punish you for growing.
How we work
ResellAIO is built and maintained by founder Alex Caceres, based in Victoria, Australia. We write the guides, fee calculators, and comparison pages on this site ourselves, and we keep them honest: fee rates are checked against each platform's published pricing, competitor comparisons credit competitors where they're genuinely stronger, and we don't publish ratings or user numbers we can't back up.
How we verify fee data: every rate quoted on our calculators — eBay final value fees, Grailed's tiered commission, Depop's payment processing, StockX seller-level fees — is verified against the platform's official pricing pages, or against multiple independent sources when a platform blocks automated access to its fee pages. We re-check rates quarterly and whenever a platform announces a pricing change, and each calculator carries the date its rates were last confirmed. Rates last verified: July 29, 2026. If you spot a rate that has changed before we have, email us and we'll fix it.
Our fee calculators and guides are free and useful whether or not you ever sign up.
Multi-currency support (USD, EUR, GBP, CAD, AUD, JPY) because reselling doesn't stop at one border.
Meet the founder
Alex started reselling the same way most people do: flipping sneakers and streetwear on the side, tracking everything in a spreadsheet, and slowly realising the spreadsheet was lying to him. Fees were estimated instead of calculated, shipping costs went missing, and "profitable" flips turned out to be break-even once every cost was counted. ResellAIO is the tool he built to fix that for his own operation first — selling across eBay, StockX, Grailed, and Depop from Australia, where multi-currency math makes sloppy tracking even more expensive.
Alex builds the product, maintains the fee-calculation engine, and writes the guides and calculators on this site. When a marketplace changes its fee structure — like Grailed's move to tiered commissions or eBay's 2025 rate increase — he's the one updating both the calculator logic and the documentation, which is why they never disagree with each other.
