Know exactly what your card collection is really costing you.

Card Vault tracks what you paid, what you sold, and what you actually made — even when the numbers come from breaks, bulk lots, or one card at a time. Every cost and every sale, in one place.

Spreadsheets don't understand breaks and bulk lots.

When you buy into a break or a bulk lot, what did any one card actually cost you? When you bundle a sale, what did any one card actually sell for? Most collectors either guess or stop tracking it altogether.

Card Vault splits the cost and the revenue the right way — evenly across a break, proportionally across a sale — so the numbers are always real.

How it works

1
Log what you buy
A single card, a live break, a box break, or a bulk lot — whatever you actually pay for.
2
Costs split automatically
A break's cost splits evenly across the cards you pull. A bulk lot follows the same rule.
3
Log what you sell
One card at a time, or several bundled together for one price.
4
See the real picture
True cost, true profit or loss — per card, and across your whole collection.
Dashboard
Total spent, total sales, net profit/loss, and a profit-by-sport chart at a glance.
Collection
Every card you own, searchable and filterable by sport.
Breaks
Live and box breaks — cost splits evenly across whatever you pull.
Batches
Bulk buys and bundled sales — cost and revenue split fairly across every card.
Sales
Every card you've sold, with real profit or loss, searchable by date.

Seller Mode

Build a live quote for an in-person deal. Pick cards from your collection, set a price or a markup % for each, then negotiate with a slider — the total and your margin update as you go. Confirm, and it's recorded as a real sale at the exact price you agreed, not a guess split after the fact.

Select a few cards from your collection right at the table.
2
Set a price or a markup %
Per card, or bump the whole deal up or down as you negotiate — the total updates live.
3
Confirm & it's logged
