Device condition grading guide for buyback merchants

Grading is where a buyback business makes or loses money. Grade a device too generously and you overpay at intake and lose again at resale. Grade too harshly and sellers walk away feeling cheated. The whole trade-in relationship rests on a grade that is consistent, defensible, and tied to something you can point at. This guide lays out a clean four-grade system, what each grade means in practice, and how a questionnaire-based grade keeps grading honest across every staff member and every device.

Why grading discipline matters

A grade is a promise about resale value. When you quote a customer, you are really saying “this device is worth X to me after I resell it, minus my margin.” If your grading drifts — one staff member calls a scuffed phone “good,” another calls it “fair” — your buy prices become inconsistent, your resale expectations get out of sync with reality, and disputes multiply.

A shared rubric fixes that. When everyone grades against the same four buckets with the same criteria, quotes are consistent, margins are predictable, and a customer who disagrees can be shown exactly why their device landed where it did. Grading feeds directly into pricing, so it is worth reading alongside buyback pricing strategy and margins.

The four grades

The platform uses four condition grades, in descending order of value:

like-new — Looks and works as if barely used. No visible screen or body flaws, fully functional.
good — Light, normal wear. Fully functional with only minor cosmetic marks.
fair — Visible cosmetic damage such as dents or notable wear, but still working.
broken — Does not power on, has a cracked screen, or has functional faults.

Keeping it to four grades is deliberate. Fewer, clearly separated buckets are easier to apply consistently than a ten-point scale where the difference between a 6 and a 7 is a matter of mood.

What each grade means for screen, body, and function

The grade is driven by three dimensions — screen, body, and function — plus whether the device powers on at all. The logic is simple and worth internalizing:

Power and function come first. If the device does not power on, the screen is cracked, or there are functional issues, it is broken regardless of how clean the body looks.
Body damage caps the grade. A working device with a dented or notably worn body is fair, even if the screen is flawless.
Flawless screen and flawless body is the top grade. When both the screen and body are flawless and the device works, it is like-new.
Everything else in between is good. A working device with minor wear that is neither dented nor flawless lands in good.

A grading rubric

Use this as the shared reference for staff intake:

Grade	Screen	Body	Function	Powers on
like-new	Flawless, no scratches	Flawless, no marks	All features work	Yes
good	Minor marks, no cracks	Light normal wear	All features work	Yes
fair	Wear or scuffs, not cracked	Dents or notable wear	Works, may have minor quirks	Yes
broken	Cracked or non-functional	Any	Functional faults present	No, or with faults

The rubric intentionally resolves top-down: check power and function, then screen cracks, then body damage, then cosmetic wear. The first failing criterion sets the ceiling. A pristine-looking phone that will not boot is broken, full stop — and pricing it as anything else is a loss waiting to happen.

How questionnaire-based grading works

Free-form hand-grading is slow and inconsistent. The platform standardizes it with a short condition questionnaire. The customer (online) or your staff (at the counter) answers a few plain questions — does it power on, is the screen flawless or cracked, is the body clean or dented, are there any functional faults — and those answers map deterministically to one of the four grades above.

Because the same answers always produce the same grade, everyone works from the same rules instead of a personal opinion. That does two things:

It standardizes intake. New staff grade like experienced staff because the questionnaire applies the same criteria every time — no photo analysis or guesswork involved.
It creates a record. The condition answers and the resulting grade are attached to the order.

Quoting from the questionnaire is unlimited and never draws on your AI quota. See features for the full platform lineup.

Why a consistent questionnaire cuts disputes

Most trade-in disputes come down to “you graded my device unfairly.” When the grade is just a staff opinion, that argument has nowhere to go. When the grade comes from a fixed set of condition answers and a consistent rubric, it does.

The answers are attached to the order. If a device arrives worse than described, the recorded condition answers and grade explain exactly why the refund differs from the estimate.
The estimate sets expectations honestly. Customers who answer the condition questions accurately up front get a value that reflects reality, so there is less gap between the quote and the final refund. This matters most in the net trade-in model, where value is confirmed only after inspection.
Consistency removes the “other shop said X” argument. When your grading is defensible and repeatable, you are the shop with the honest, documented process.

Lower disputes mean fewer chargebacks, fewer returns, and less staff time spent arguing over condition — all of which protect the margin you set at intake.

Edge cases and how to grade them

The four-grade system is deliberately simple, but real devices bring judgment calls. A few common ones and how the top-down rubric resolves them:

Flawless body, dead battery that still powers on via cable. If a core function like holding a charge is impaired, treat it as a functional issue — that pushes it toward broken, or fair at best if it is a cheap fix you will handle.
Pristine screen, cracked back glass. Back-glass damage is body damage. A working device with a cracked back is fair, not good, because the body dimension caps the grade.
Perfect condition, but activation-locked. Cosmetics do not matter if you cannot reset and resell the device. An account-locked phone is effectively unsellable until unlocked, regardless of how it looks — verify lock status before grading value into it. See avoiding stolen phones and IMEI blacklists.
Light scuffs plus a hairline screen scratch you can feel. A scratch that catches a fingernail but is not a crack keeps the device out of like-new and into good.

The rule that resolves nearly all of these: the first failing dimension sets the ceiling, checked in order of power/function, then screen cracks, then body damage, then cosmetic wear.

Calibrating your team

A rubric on paper is only as good as the shared understanding behind it. When you onboard staff, grade ten real devices together and talk through each call before trusting anyone to grade solo. Revisit the calibration periodically — grading standards drift, especially when the pressure is on to close an acquisition. The questionnaire is a useful anchor here: when a staff member’s instinct diverges from the grade the condition answers produce, that gap is a coaching moment, not just a data point. Over time the goal is that any two people on your team, handed the same device, land on the same grade — which is exactly what makes your buy prices consistent and your quotes defensible.

Grading in the wider workflow

Grading does not stand alone. It sits between intake and pricing in the buyback loop:

Identify the device and capture the IMEI — see avoiding stolen phones and IMEI blacklists.
Grade the condition with the rubric and the condition questionnaire.
Pull the market price for that model and grade, then apply your margin.
Verify the device is clean, pay, and record the acquisition.
Refurbish if needed and resell — the AI listing writer turns the graded device into a ready-to-publish listing.

Grading and resale value

The reason grading discipline pays off is that the grade travels all the way to the resale listing. A device you graded honestly at intake is a device you can describe accurately when you resell it, which means fewer returns and fewer unhappy buyers on the other side of the transaction. When the AI listing writer turns a graded device into a resale listing, it is working from the same condition data your staff confirmed — so the story you tell a buyer matches the story you told the seller. That internal consistency is quietly one of the most valuable things a shared grading system buys you: the grade is not just a number you use to set a buy price and then discard, it is the through-line from acquisition to resale. Undermine it with a generous intake grade and you inherit the mismatch at the far end, when a buyer receives a device that does not match its description.
