About My Card Inventory
My Card Inventory is a collection tracker for sports and trading card collectors. It can read your purchase and sale emails and turn them into a running inventory with real cost basis and profit. You can also use it to scan cards, clean up photos for listing, track where every card is stored, list cards straight to eBay and Shopify, and see analytics on your collection so that you can spend your time collecting instead of cataloging.
Collectors buy and sell cards across a variety of marketplaces, and keeping up with all of it means manually updating a spreadsheet or app every time. It's a lot of work, and it's the first thing to fall behind.
My Card Inventory aims to streamline that process as much as possible, so you can focus on building your collection instead of cataloging it.
What it does for you
Forward a receipt and this part happens on its own.
- Reads the card, the price, the shipping, the fees and the tax out of the email, and splits the shared costs across the cards in an order, so each one carries what it actually cost you rather than its sticker price.
- Recognizes a repeat of a receipt you already forwarded, so the same order doesn't land twice.
- Matches a “you sold it” email against the cards you own, records the sale price and fees, and moves it into realized profit. A multi-card order is recorded as one sale, not several.
- Puts every imported card in a review queue first. You approve what enters your inventory; nothing is added behind your back.
What else you can do with it
The rest is yours to drive. None of it needs an email, and all of it works on cards you typed in or imported from a spreadsheet.
- Add cards by hand or upload a spreadsheet, with photos, notes and your own tags.
- Scan a card with your phone to fill in its details, then clean up the photo with the built-in background remover.
- Group by set, player, sport, or anything you invent.
- Record where each card physically lives, which bin and which slot, and find it again when it's time to ship.
- List a card straight to eBay or Shopify, with the title, item specifics, photos and description built for you. You always set the price and approve the listing before anything goes live.
- Bulk-list a whole pile at once from a batch of photos.
- Log sales, trades and expenses, and watch cost basis and realized profit follow.
- Set each marketplace's fees once, so the profit on a sale is the real number.
- See your whole portfolio at a glance, and use the free calculators for net profit, where to sell, and grading ROI.
- Export everything, any time. It's your collection and your data.
What makes it different
- Versus a spreadsheet: a spreadsheet needs you to type in every card, price and sale by hand. Here the receipts do that, shipping and fees get split across the cards in an order, and profit and loss stay current as you buy and sell.
- Versus a price guide: price-index apps tell you what the market is doing. My Card Inventory tracks your cards, what you actually paid, and what you actually made, so the numbers are yours rather than an average.
- Versus a scanning app: scanning gets a card into a list, but you still enter what you paid and what you sold it for. Reading the receipt captures both sides for you.
- Priced around the free part:the collection itself is free for as long as you want it, including photos, groups, storage locations, sale logging and your portfolio. You pay only for the automations that save the most time, like reading your receipts for you and listing straight to eBay and Shopify. It's month to month, and you can export or delete everything any time.
Who it's for
- Collectors who buy across eBay, Fanatics Collect, COMC, CollX and more and lose track of it all.
- Part-time flippers who need a real cost basis and honest profit on every card.
- Set and player-collection builders who want one organized, searchable home for everything.
- Anyone who wants to know where a card physically is when it's time to ship it.
Who's behind it
My Card Inventory started as a personal project, when I couldn't find any apps to help me scale my card business and manage my buying and selling. It started with the same problem that many collectors probably have: cards coming in from too many places, and a spreadsheet that was always a few purchases behind. The goal is a tool that keeps up on its own, treats your data as yours, and stays honest about what it does and doesn't do.
