Frequently asked questions

How does TWICE handle IMEI tracking and unique devices?

Used phone inventory is highly granular — every device has its own IMEI, specs, and condition. TWICE uses single‑item tracking so each phone carries its own data: IMEI/serial, model, storage, carrier status, grade, battery health, intake source, cost, and sales history. You always know which devices are available, where they are, and which channel they’re listed on, without relying on spreadsheets.

Can TWICE support trade‑ins, buybacks, and consignment for phones?

Yes. TWICE is built to handle multiple sourcing models. You can run consumer trade‑ins in store or online, manage buyback programs where you purchase devices outright, or track consignor agreements and payouts. All intake types live in the same system with clear cost, margin, and payout visibility per device.

Does TWICE connect online phone sales with my physical locations?

Yes. TWICE centralizes inventory across your online store, repair shops, retail locations, and warehouses. Every sale or trade‑in updates stock in real time, preventing the same IMEI from being sold twice. In‑store POS flows and online checkout stay in sync through one recommerce‑focused backend.

How does TWICE help standardize grading and pricing for used phones?

TWICE lets you define grading schemas based on the criteria that matter for phones: cosmetic wear, battery health, display condition, carrier status, and functionality. Your team captures this data through guided fields at intake, and you can apply pricing rules by brand, model, storage, and grade to keep valuations consistent — while still allowing manual adjustments for special cases or market changes.

Can I keep my existing website and use TWICE just for resale operations?

Absolutely. Many partners keep their current marketing or retail site and use TWICE as the dedicated engine for used phones. You can link out to your TWICE‑powered store, embed components, or connect via integrations depending on your stack. TWICE handles device intake, inventory, orders, and lifecycle tracking, while your existing site remains the customer‑facing front.
