Collectibles inventory changes constantly, and value often sits in individual items. TWICE uses single-item tracking so each card, comic, figure, or signed piece carries its own record: condition, grading, provenance, purchase cost, asking price, and sales history. You always know exactly what you have, where it is, and what it’s worth without relying on manual spreadsheets.

You can run trade-in or buyback programs where you pay cash or store credit, track full collection purchases, or operate consignment with configurable commission rates and payout schedules. All models live in the same system so your sourcing remains structured and auditable.
