Turn repaired devices into certified resale inventory.
Synapse gives repair shops a repeatable way to inspect, certify, and resell used iPhones — so a finished repair becomes a listing buyers can verify.
- Test before you list
- Verifiable certificates
- Technician seats included
A good repair still needs proof before it sells
Fixing the device is half the job. Confirming everything else still works — and proving it to a buyer — is what turns a repair into resale-ready inventory.
Listing without verification
- A repair confirms one fix, not the whole device
- No record that cameras, sensors, and audio still pass
- Buyers take your word on overall condition
- Returns when an unrelated fault shows up later
- No shared standard as more techs handle resale
Listing with a certified check
- A full 50-point inspection checks the whole device
- Pass and fail counts are recorded on a certificate
- Buyers verify the result themselves, no login
- Documented results reduce post-sale surprises
- Every tech runs the same check before listing
A repair-to-resale workflow you can repeat
Finish the repair, run the inspection, certify the result, and list with proof attached.
Inspection before listing
Plug in the device and run a full check after the repair — confirm the fix held and that everything else still passes before it goes up for sale.

Display, touch, cameras, speakers, microphones, sensors, Face ID or Touch ID, haptics, buttons, battery health, and connectivity — measured on-device.
See the inspectionA certificate for resale
Each check issues a tamper-evident certificate with model, iOS, capacity, pass and fail counts, inspection date, and result — non-PII facts only.
Explore certificatesProof buyers can verify
Buyers scan a reference and confirm the certificate with no account. A refunded purchase invalidates it, so the proof you attach stays honest.
How verification worksSeats for your bench
Every plan includes technician seats with owner, admin, and member roles, so multiple techs can certify resale inventory under one shared standard.
How teams workPay for the volume you do
Start small and grow. Checks draw from one shared team pool that refills each period, so your resale side scales with your repair volume.

Questions, answered
Common questions for teams like yours.
How does Synapse fit a repair shop that also resells?
After a repair, run the 50-point inspection from the Synapse iOS app to confirm the whole device passes, then issue a certificate. The finished repair becomes resale inventory with buyer-verifiable proof attached.
Does the inspection cover more than the part I repaired?
Yes. The 50-point inspection checks the whole device — display, touch, cameras, audio, sensors, Face ID or Touch ID, buttons, battery health, and connectivity — so you catch unrelated faults before you list.
Can multiple technicians certify devices?
Yes. Every plan includes technician seats with owner, admin, and member roles. Owners and admins invite techs by email up to the seat limit, and everyone runs the same inspection.
What does a buyer see when they verify a certificate?
Non-PII device facts only: model, iOS, capacity, pass and fail counts, inspection date, validity, and result. Verification needs no login, and a refunded purchase invalidates the certificate.
