About
The operating system for your collection and your business.
CollectibleIQ exists because the serious hobbyist is a dealer and a collector at the same time. Some of what you own is inventory, bought to flip, and some is your personal collection, bought to keep. Every other tool forces you to track those in two disconnected places and reconcile them in your head.
We run the whole loop, own it, list it, sell it, track the money, in one place. Connect eBay and list what you own in seconds, sold items sync back on their own, and every sale is reconciled against fees and taxes down to the penny. Inventory is the business, your collection is the passion, and a clean wall between them keeps your margins and your taxes honest.
Cards are the first category because they are the hardest, with the most demanding identity and structured data. Everything after them is downhill, and each new category reuses the same engine. It's software for people who want the truth about whether they're actually making money.
Company
A small, independent team.
We ship often, read every piece of user feedback, and reserve roughly half our roadmap for what early users tell us to build next. Contact us at hello@collectibleiq.com.
Data sources
Where our numbers come from.
Trust in a financial tool starts with sourcing. Every number in CollectibleIQ traces back to one of four inputs, and we don't guess or estimate when we don't have the data.
Topps official odds sheets
Every pack odds number, every parallel print run, and every SKU availability note in our interactive checklists comes directly from the manufacturer's published odds sheet — never inferred or crowdsourced.
Beckett enrichment
Card-level metadata — rookie flags, subset classifications, player disambiguation — is cross-referenced against Beckett's checklist data and normalized into our canonical catalog.
Your connected eBay account
Once you connect eBay, your listings, sales, and purchases flow in and sold items sync back automatically. We parse gross sale price, final value fee, payment processing, promoted listing fees, shipping labels, and refunds, the complete fee stack that determines your real P&L.
Your own costs
Purchase price, shipping in, sales tax, and fees are added by you at entry or via import. Cost basis is never guessed, it's what you actually paid, tracked to the penny in integer cents.

FAQ
Common questions.
The answers below are the same ones we'd give in an email. If something isn't covered, reach out directly.
What is CollectibleIQ?
CollectibleIQ is the seller operating system for people who own collectibles as both a business and a passion. You connect eBay, list what you own in seconds, and sold items sync back automatically. It tracks cost basis, calculates real P&L after every fee, and generates tax-ready reports. It holds your inventory (what you sell) and your personal collection (what you keep) in one place, with a clean wall between them. Cards are the first category, with more coming.
How does CollectibleIQ calculate P&L?
Cost basis is purchase price plus shipping in, sales tax, grading fees, platform fees, payment fees, and any consignment fees or adjustments. Net proceeds is sale amount minus final value fee, payment processing, and shipping out. Profit is net proceeds minus cost basis, and ROI is profit divided by cost basis. Every value is computed as integer cents — never floating-point — so your numbers are accurate to the penny.
Is CollectibleIQ free?
Yes. The free tier gives you unlimited items in your collection, unlimited import, and full books, with up to 10 active eBay listings at a time. Paid plans start at $19 per month and raise the active-listing limit as you sell more. Every new signup gets a 30-day trial of a paid plan with no credit card required. See the pricing page for the full ladder.
Where does the checklist data come from?
Every checklist is sourced directly from the manufacturer's official odds sheet and checklist PDF — Topps for Chrome and flagship products — then enriched with Beckett's player and subset data. Serial numbers, pack odds, and SKU availability (Hobby vs Jumbo vs Mega vs Value) are verified against the published odds sheet on release day. We do not crowdsource checklists.
Which sports does CollectibleIQ support?
The tracker supports any sport or category — baseball, football, basketball, hockey, soccer, racing, Pokemon, and non-card items like wax, memorabilia, and equipment. Our interactive public checklists currently focus on Topps Chrome Football with additional Topps releases rolling out through 2026.
How does CollectibleIQ handle grading costs?
Grading fees are a transaction type in the financial engine. When you submit a card to PSA, BGS, CGC, or SGC, you log a grading transaction with the service cost, shipping to the grader, and return shipping. Those costs roll into the card's cost basis automatically, so when it sells the P&L reflects the full out-of-pocket spend.
How does CollectibleIQ help with 1099-K reconciliation?
eBay issues a 1099-K for gross sales above the federal threshold. CollectibleIQ's 1099-K reconciliation report compares what eBay reported as gross proceeds against your actual taxable income after fees, shipping, and refunds. The gap between the 1099-K number and your Schedule D number is usually thousands of dollars for active sellers — we show you that gap line by line.
Who built CollectibleIQ?
CollectibleIQ is built by a small independent team. We started it because the serious hobbyist is a dealer and a collector at the same time, and every tool forces them to pick one. Marketplace tools ignore the collection, collection apps ignore the business, and nobody runs the whole loop or shows the real P&L a seller sees after the marketplace takes its cut.
