Inventory, quantity and order safety in the marketplace
Cards with an accepted offer are held so they can't be sold twice, a paid sale elsewhere always wins, and quantities, budgets and orders stay correct even when many people act at once.

Overview
When a seller accepts an offer, the cards are held in SlabIQ inventory so stores, the kiosk and other offers can't take them, while they stay listed elsewhere. If the card sells and is paid for on another marketplace first, that sale wins: the hold is released and both sides are told. When the buyer approves, the sale is recorded once and every other listing is lowered or ended. Two sellers can't spend the same buyer budget at the same moment, and each offer can become only one purchase.
Completed work
- Inventory holds on accepted offers through the shared inventory ledger
- A paid sale on another marketplace releases the hold and wins
- Approved purchases recorded as one sale that updates every listing
- Cancellations and returns restock safely, never more than was sold
- Budget and quantity limits enforced when many sellers act at once; one purchase per offer
- Exact catalog identity on every line; uncertain cards are never priced
