GrailCheck

Know what you keep before you sell a card. A card's sale price isn't your profit. GrailCheck shows trading card and sports card sellers their estimated profit after selling fees, shipping and what they paid, then tracks every buy and sale in one place. PROFIT AFTER FEES Enter a sale price and pick where you're selling. GrailCheck estimates the platform fee for eBay, TCGplayer, Whatnot, Mercari or Facebook sellers, adds buyer-paid shipping, subtracts your shipping cost and card cost, and shows your net profit and ROI. You can enter your actual fees instead when you have them. SCAN A CARD TO START Snap a photo to help fill in card details, then review them. Where available, view TCGplayer market prices and eBay asking-price medians. Open eBay to view sold listings. INVENTORY THAT KNOWS YOUR COST Track each card's cost, condition, photos, notes and sales, including partial sales and returns. Bought a lot? Split its cost across the cards in it. Your inventory is stored on your device. PROFIT TOTALS AND SOURCE ROI See your cost basis, revenue, cost of goods and net profit at a glance. With Basic or Pro, open full reports: aging inventory, tax year, monthly P&L, profit by platform, and ROI by where you bought, whether that's card shows, garage sales, online or trades. SHARE A DEAL RECEIPT Share an image of your estimated profit breakdown. Your first Deal Receipt is free; Basic or Pro lets you share more. TAX-TIME RECORDS Log expenses and mileage, see a Schedule C-style estimate and compare it against your 1099-K. With Basic or Pro, export CSV files to share with your tax professional, including a sales CSV for this year, last year or a custom date range, with one row per sale and return showing date, item, platform, sale price, fees, shipping, cost basis and net profit. These are planning estimates, not tax advice. PLANS GrailCheck is free to start with up to 15 inventory items, 3 AI card scans a month and a monthly allowance of AI listing drafts. The fee calculator, summary totals and your first Deal Receipt are free. Basic adds unlimited inventory, tax and CSV exports, full reports and unlimited Deal Receipts. Pro includes everything in Basic plus expanded AI scans and listing drafts, and comes with a 1-week free trial for eligible new subscribers. Basic is billed monthly and Pro monthly or annually, as auto-renewing subscriptions. The App Store shows prices and any free-trial eligibility before you buy. Fee and profit figures are estimates. Actual marketplace fees depend on your account and sale. GrailCheck isn't affiliated with eBay, TCGplayer, Whatnot, Mercari or Facebook.
