Never overpay for a phone again.

Every phone in front of you is either profit or a lesson. Know which one before your money leaves your pocket: daily marketplace comps, estimated take-home after fees, and the max price you should pay for the exact device spec.

Estimated fees use Andover's default conservative all-in selling-cost profile off the final retail price, including marketplace and payment-processing assumptions. Exact fee tiers, shipping and expenses are configurable in Pro. Listings may sit above your max buy price. That is the point: it is your ceiling, not a promise.

latest data update

Data points are stored pricing fields. Observations are cleaned daily price records. Every number traces to a real spec, source and timestamp.

Three steps. No spreadsheets.

From “what's it worth?” to a confident buy.

1

Match the exact device

Model, storage, condition and lock status, so you compare like for like, not vibes.

2

Compare buy, sell, fees and net

Lowest verified buy, highest sell, and your estimated net after marketplace fees.

3

Buy only when the math works

Skip the devices that won't clear your margin. Commit when the number is real.

ARBITRAGE FINDER

Pro finds the flips for you.

Every morning, Pro ranks buy-low, sell-high opportunities across the market, nets out fees, and scores each with the Andover Market Signal (AMS), our confidence rating that the deal holds. You wake up to a ranked list.

Real deals from the latest snapshot, net of estimated fees and shipping. Pro shows every qualified opportunity, ranked. Verify live availability before buying.

Built for the counter, the couch, and the warehouse.

Different operations, same question: what is this phone actually worth to me?

🛠

Repair shops and buyback counters

Your staff plugs the device into the calculator and quotes a buyback on the spot. No more calling the owner on their day off to ask what they can pay.

📱

Solo flippers

Price the marketplace deal before you commit. Know your ceiling, your exit path, and your estimated take-home in the parking lot, not after the sale.

📦

Wholesalers and volume buyers

Set target margins across whole lots, watch depreciation on what you hold, and route inventory to the exit that pays.

WHY NOW

Resale is exploding. Guesswork isn't keeping up.

Recommerce is heading toward a trillion-dollar global market. The resellers who win it will price on data, not gut feel. Andover is the pricing intelligence layer built for exactly that.
