Frequently asked questions

How does TWICE handle unique, high-value jewelry items?

TWICE is built for one-of-a-kind inventory. Each piece — from a simple gold band to a certified diamond or luxury watch — gets its own record with condition, specs, photos, certificates, ownership history, purchase price, and sale data. You always know where it is, what it’s worth, and whether it’s ready to list or already reserved, without relying on manual notes or spreadsheets.

Can TWICE support both consignment and buyback/trade-in models for jewelry?

Yes. TWICE is designed for multiple intake models. You can track consignor agreements, split rates, settlement cycles, and unsold returns alongside buyback and trade-in flows where you own the inventory outright. All models run in the same system, so sourcing pre-owned jewelry stays structured, auditable, and easy to scale.

How does TWICE help with authentication and certifications?

TWICE doesn’t replace your gemologists or watchmakers — it gives them structure. The platform lets your team record metal purity, gemstone details, serial numbers, hallmarks, and grading notes using standardized fields. You can upload lab reports (e.g., GIA certificates), appraisals, and service records directly to each item, then surface that information clearly on the product page to build buyer trust.

Can TWICE connect our in-store jewelry operations with online resale channels?

Yes. TWICE centralizes inventory across showrooms, backrooms, warehouses, pop-ups, and your online store. Every sale updates stock in real time, so a one-of-one ring or watch can’t be sold twice. In-store POS flows and online checkout stay synced through one backend, giving you a single source of truth for availability and pricing.

How does TWICE support pricing for used jewelry with changing market values?

With TWICE, you can combine expert appraisals with pricing rules. Capture your team’s valuation inputs at intake, then apply automated rules based on brand, metal type, gemstone category, condition, or age of listing. You can also run bulk price updates when metal spot prices or demand shifts, ensuring your catalog remains competitive while protecting margins.
