Trade-in & buyback device diagnostics that protect payout margin

Trade-in device testing is how you stop paying full grade for a phone that fails on audio, cameras, or locks after the customer has left. Check Up is diagnostics-first software for trade-in / buyback shops and shops that buy used phones — Instant Diagnostics, Mobile App Diagnostics, grading, PDF reports, and (on Premium) IMEI blacklist plus carrier lock.

The cost of a bad buy

Trade-in margin dies in predictable ways:

  • Function fails you didn’t catch — dead mic, cracked rear camera that still “looks fine,” flaky sensors
  • Locks and accounts — iCloud/FMiP/MDM and similar signals when available at intake
  • Blacklist / carrier-lock risk — paying out before you know the device’s status
  • Inconsistent grading — Grade B on Monday isn’t Grade B on Saturday if every tech grades from memory

Larger buyback platforms exist for high-volume programs. Many shops need something simpler: fast, consistent diagnostics, clear reports, and a price that makes sense before the next payout window.

Workflow: station → grade → document → optional secured data erasure

  1. Agent / station — Bring the device to the Check Up agent/station workflow

  2. Instant Diagnostics — Internal + interactive diagnostics for iOS and Android

  3. Mobile App Diagnostics — Display, cameras, audio, sensors, controls, connectivity

  4. Device info / locks when available — Specs, SIM, battery, lock-related status (iCloud/FMiP/MDM and similar); service history available so you know what’s been replaced (iOS)

  5. IMEI blacklist & carrier lock (Premium) — 55 blacklist/mo; carrier lock check included to sample (add-on packs if you need more)

  6. Grade — Apply grading profiles so payout language stays consistent

  7. PDF reports & labels — Hand the next person a record, not a verbal “looked OK”

  8. Optional secured data erasure — for a clean handoff when the device leaves the bench

Device history stays in your workspace (1 month Free · 6 months Premium).

Blacklist & carrier lock on Premium

A carrier (or network/SIM) lock check shows whether a device is locked to a carrier or unlocked. If it’s locked, shops need to know which carrier, whether that carrier fits the buyer (you don’t want to be stuck with a phone locked to a carrier that doesn’t matter to the customer), how lock status changes device pricing, and whether there are financial obligations on the device — separate from IMEI blacklist status.

Free is for proving diagnostics.

Premium adds:

  • 55 IMEI blacklist checks per month
  • Carrier lock check included to sample (add-on packs if you need more)

Use Free while you validate Instant Diagnostics and Mobile App Diagnostics on trade-in intake. Upgrade when buying devices is part of the job and you need risk checks before cash out.

Start Free for diagnostics — upgrade when you’re buying.

Deep dive: IMEI blacklist check for business · Carrier lock vs blacklist

Built for trade-in & buyback desks

Check Up is for:

  • Trade-in / buyback shops that need functional testing before payout
  • Shops that buy used phones and want grading + PDF documentation
  • Repair shops that also run a trade-in counter and need one diagnostics station

Check Up is diagnostics-first — not a full buyback POS or inventory commerce suite. If you need station diagnostics, grading, reports, and clear Free → Premium pricing, you’re in the right place.

Pricing — Free vs Premium

Free — $0 / €0 / £0

  • 5 device checks / mo · Multiple stations (workspace-wide limits) · 1 month history

Premium — US $25 / EU €21.90 / UK £19.90

  • 250 device checks / mo
  • 55 IMEI blacklist · Carrier lock check included to sample (add-on packs if you need more)
  • Multiple stations (workspace-wide limits) · 6 months history · users & roles

Upgrade when: you’re out of checks, trade-in volume needs blacklist/locks, you need separate logins/permissions (users & roles), or longer history.

Grading + reports that survive a dispute

Payout arguments often start with “you said it was fine.” Trade-in desks that export PDF reports and labels and apply grading profiles have a record: what failed on Mobile App Diagnostics, what device info showed, what grade was assigned, and — on Premium — whether blacklist or carrier lock was checked within plan limits.

Build the habit:

  • Same Instant Diagnostics path every unit
  • Same Mobile App categories every unit
  • Grade from a written profile, not from shift mood
  • Label the bag/bin so the next person doesn’t re-guess

For the full grading framework, see How to grade a used phone for trade-in. For station cabling and flow, see USB agent diagnostics station setup.

Free → Premium for buy desks

Start Free when you need to prove diagnostics this week without a purchase order. Upgrade to Premium when:

  • You’re buying enough phones that 5 checks/mo isn’t enough
  • You need IMEI blacklist (55) or a carrier lock sample before payout
  • You need separate logins and permissions → Premium users & roles (Free already supports multiple stations; limits are workspace-wide)
  • You want 6 months history

Questions, answered

Frequently asked questions

How does Check Up reduce trade-in payout risk?

By running Instant Diagnostics and Mobile App Diagnostics before you pay out, documenting grades with PDF reports/labels, and — on Premium — running IMEI blacklist and carrier-lock checks within plan limits.

What’s included on Free for trade-in desks?

Free includes 5 device checks/mo, multiple stations (workspace-wide limits), and 1 month history for diagnostics, grading, and reports. Blacklist (55/mo) and a carrier lock sample are on Premium (add-on packs if you need more).

What kind of wipe does Check Up support?

Secured data erasure for a clean handoff — when the device leaves the bench and your process requires a clean handoff.

How does Check Up compare to larger buyback platforms?

Larger suites often bundle commerce, inventory, and enterprise workflows. Check Up leads on diagnostics-first freemium clarity and published Premium pricing for repair & trade-in shops. See also Check Up vs NSYS.

Can I grade trade-in phones consistently?

Yes — use grading profiles so each grade means the same thing across shifts, then export PDF reports and labels, device history reports.

Is Check Up a full buyback POS?

No. Diagnostics-first — not a full POS.
