Frequently asked questions

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

Every pair of sunglasses in TWICE is tracked as a unique item with its own record. You can store lens and frame condition, brand, model, size, intake source, costs, photos, and authentication notes. Real-time stock updates prevent double-selling, and item histories let you see where each pair came from, how it was priced, and how quickly it sold.

Can TWICE support sunglasses trade-in, buy-back, and consignment models?

Yes. TWICE is designed to handle multiple sourcing models in a single system. You can run trade-in flows that issue instant credit, buy-back programs where you purchase sunglasses outright, and consignment setups that track owner shares and payouts. All financials are tied to item records, making settlements and margin calculations straightforward.

How does TWICE support grading and authenticity for used sunglasses?

TWICE lets you define standardized grading criteria for sunglasses, including lens wear, frame condition, hinge stability, and overall grade. You can capture close-up photos, record serial numbers or model codes, attach receipts or certificates, and log internal authentication checks. This structured data flows directly into your listings, improving buyer trust and reducing returns.

Can I connect my existing eyewear website or retail system to TWICE?

Absolutely. Many businesses keep their existing e‑commerce site or POS as the customer-facing layer while using TWICE as the resale engine behind it. You can connect via integrations, embed resale components, or link to a dedicated secondhand store powered by TWICE. Inventory, orders, and item lifecycles remain centralized in one place.

What about multi-location optical stores or franchises?

TWICE centralizes used-sunglasses inventory across multiple stores, pop-ups, and warehouses. You can route trade-ins to specific processing hubs, see what’s available in each location, and reallocate high-demand brands or styles quickly. All channels pull from the same source of truth, so staff know exactly what can be sold where, and reporting rolls up at the network level.
