How to resell used phones (every major brand).

All-brand phone resale is the broadest scope an operator can take on. Each brand routes to different marketplaces, prices against different competitors, and serves different buyer segments. Multi-brand operators capture volume; brand-specialists capture margin.

This playbook references the per-brand T7 guides (iPhone, Samsung, Android long tail) for brand-specific detail. The all-brand shared workflow is: brand-aware sourcing, multi-channel routing, per-brand pricing tracking.

US used phone market: approximately $22-$26B/year across all brands. iPhone ~55%; Samsung ~20%; Pixel + OnePlus + Motorola + Sony ~25%.

The five highest-leverage channels for phones inventory. Ranked by long-term margin and ease-of-access for a small operator.

• Your own buyback storefront. Best long-term channel — captures all brands from local trade-ins.
• Carrier returns wholesale. Multi-brand mixed lots from AT&T / T-Mobile / Verizon.
• Brand-specific trade-in returns. Apple, Samsung, Google all run trade-in programs that off-load to wholesalers.
• B-Stock auction lots. Mixed-brand returns from retail (Best Buy, Walmart, Target).
• Enterprise ITAD refresh. Corporate fleets — usually Samsung Knox-managed or Google-managed Android.

Four pricing rules that work for phones resale at small scale. Each is calibrated against real marketplace data, not aspirational margins.

• Route per brand: iPhone → Swappa + Back Market. Samsung → eBay + Back Market. Pixel → Swappa + /r/Pixel. Motorola → Amazon Renewed. Budget Android → Mercari.
• Per-brand inventory turn target: iPhone 7-14 days; Samsung 14-21 days; Pixel 7-14 days; Motorola 14-30 days; Budget Android 30-45 days.
• Per-brand margin tracking: track each brand separately. Top-margin brand subsidizes the lower ones; without tracking, you can't see which to optimize.

Per-device packaging and insurance guidance. Skipping insurance on a $500+ device once is the lesson most resellers only need once.

• Brand-specific packaging. iPhone (glass back): padded box. Samsung (curved screen): edge protection. Pixel + Motorola: standard. Foldables: specialty packaging.
• Insurance thresholds. Premium tier ($400+): declared-value insurance. Budget tier: standard carrier insurance.
• Signature confirmation. For all phones over $300 resale.

The top return reasons for phones resale, with operator-grade responses. Pre-empting these in your listing reduces returns by ~30%.

• Brand-specific top returns. iPhone: Activation Lock + battery health. Samsung: Knox status + S-Pen function. Pixel: bootloader + fingerprint. Motorola: charging port wear. Pre-empt all with proper documentation.

Generic across device class — the buyback business is a working-capital business with consistent tax structure regardless of what you resell.

• LLC or S-Corp. Most small operators run an LLC for the first 12-24 months, then convert to S-Corp once income exceeds ~$60K/year for the payroll-tax savings.
• Sales tax. Buyback (paying the seller) doesn’t trigger sales tax. Resale (selling the refurbished device) does — register for sales tax in the states you’re selling into.
• Inventory accounting. Use specific-identification (track each device’s buy + sell price) for the first 50-200 devices. Convert to FIFO once volume makes specific-identification impractical.
• Secondhand dealer license. Some US states (CA, NV, WA) require a secondhand-dealer license for resellers accepting devices from individuals. Check your state — most license applications take 2-4 weeks and cost $100-$300/year.
