Frequently asked questions

How does TWICE handle unique, one-of-a-kind collectibles?

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.

Can TWICE support trade-ins, buybacks, and consignment for collectibles?

Yes. TWICE is built to handle multiple sourcing models for collectibles. 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.

Does TWICE connect my in-store and online collectibles sales?

Yes. TWICE centralizes inventory for your shop, warehouse, pop-up booths at shows, and online channels. When an item sells in-store or at an event, stock updates in real time across your online store and connected marketplaces, helping you avoid double-selling a one-of-a-kind collectible.

How does TWICE support grading, authenticity, and provenance?

TWICE provides customizable fields and workflows for recording grading company, grade, serial numbers, signatures, and provenance details. You can attach certificates of authenticity, slab photos, and documentation directly to each item. This data then flows into your product pages, building trust with buyers and supporting higher sell-through at target prices.

Can I keep my existing website or marketplace presence and still use TWICE?

Absolutely. You can keep your current website and marketplace accounts while using TWICE as the operational engine behind your collectibles resale. Connect via integrations or use TWICE as your primary catalog and order management layer. TWICE handles inventory, pricing, and order workflows so your front-end channels stay consistent and up to date.
