Built for the hobby

Everything a card investor needs.

Stop juggling spreadsheets, eBay tabs and gut feelings. CardVault turns the whole grind into one fast, data-driven workflow.

Find the steals

Vault Scores surface underpriced rookies and breakout candidates before the market catches on — with a Steal Score that rewards digging deeper than everyone else.

Real-time sync

Connect eBay and your listings, sales, returns and cancellations flow in automatically — zero manual data entry, ever.

Ship in seconds

When a card sells it lands in your Ship Queue with the buyer, address and deadline. Pick a package, buy & print the label, done.

Know your numbers

True net profit, ROI, margins, inventory age and sell-through — live and retroactive — so you never guess how you're really doing.

Vault Scores

Proprietary Buy, Momentum, Opportunity, Undervalue and Risk scores for every player and card, with the reasoning behind each one.

One portfolio

Every card, every marketplace, every gain and loss in one place — with target sell prices and appreciation tracked over time.

Spot opportunity

See the steal before everyone else.

CardVault watches sold comps, search trends and population reports so you don't have to. The cards others miss surface right at the top of your morning brief.

Hidden gems, surfaced daily

Buried, high-upside cards that reward the people who actually dig — not just whoever grabs the first listing.

The reasoning, every time

Each flag comes with the supporting data, comparable players, a confidence score and an upside estimate.

Automate the grind

It sells. We handle the rest.

The moment a card sells, CardVault ingests the sale — fees, cost to ship, net return — and drops it into your Ship Queue ready to go out the door.

No manual entry

Real-time ingestion of listings and sales. Spend your time sourcing, not typing.

Buy & print labels

Pick envelope, mailer or box; the marketplace charges postage and prints. Tracking syncs back automatically.

Tax-ready, always

Income statements and exports that make tax time a breeze — not a panic.
