If you curate pre-owned sunglasses from local sellers, online deals, or estate lots, TWICE helps you keep every pair traceable without spreadsheets. Standardize your intake, grading, and pricing, and sell across your website and marketplaces from one clean backend — so you can focus on finding inventory that moves.
Turn returns, overstock, and customer trade-ins into a profitable resale channel. TWICE lets you run structured buy-back programs, manage secondhand inventory alongside new stock, and keep availability synced across locations. Track margins, payouts, and performance so used sunglasses become a reliable revenue stream, not a side project.
For high-end and collectible sunglasses, authenticity and condition are everything. TWICE supports detailed item histories, authentication data, and nuanced pricing rules for premium brands. Give your team the tools to manage one-of-a-kind pieces confidently while giving buyers transparent, trustworthy product information.
Owned resale and trade-in programs help brands increase customer lifetime value while hitting circularity goals. TWICE provides the operating system for branded secondhand: structured take-back flows, lifecycle tracking per frame, automated credit issuance, and performance reporting across resale channels — all without building custom infrastructure.
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.
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.
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.
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.
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.
