A focused NSYS alternative for iPhone resellers.
Synapse is built for resellers and refurbishers who want buyer-verifiable certificates and a simple team workflow — focused on used iPhones rather than a broad wholesale platform.
- 50-point on-device inspection
- Buyer-verifiable certificates
- Shared team credits
Focused on the resale workflow.
Broader wholesale platforms cover wide inventory catalogs and enterprise grading. Synapse is focused on one thing — inspecting a refurbished iPhone and giving the buyer a certificate they can verify.
Capabilities that matter for resale
| Capability | Synapse | Broad wholesale platforms |
|---|---|---|
| Full iPhone hardware inspection | 50-point, measured on-device | Varies by provider |
| Buyer-verifiable certificate | Server-issued, tamper-evident | Not always buyer-facing |
| Public buyer verification | Scannable, no login required | Not always buyer-facing |
| Shared team credit pool | One pool across every seat | Varies by provider |
| Role-based access | Owner, admin, and member roles | Varies by provider |
| Built for refurbished-iPhone resale | Yes | Often enterprise-oriented |
| Transparent pricing | Public monthly plans | Often quote-based |
| Certificate invalidation after refund | Yes | May require a separate workflow |
Competitor capabilities vary by provider and plan. This table reflects how Synapse is built and where it is intentionally focused, not a claim about any specific product.
Signs Synapse is the right fit
If any of these sound like your operation, the certificate is built for you.
You resell iPhones, not a full warehouse catalog
Your focus is used iPhones. Synapse is built around that one device family, with an inspection tuned to it rather than a broad multi-category platform.
Buyers want proof, not just a grade
A grade is an internal label. A verifiable certificate is something your buyer can confirm independently before they pay.
Technicians grade inconsistently
A fixed 50-point inspection gives every technician the same checklist, so grades match across the bench.
You want public certificate verification
Buyers confirm a result from a scannable reference — no account, no login, no back-and-forth.
You want simple monthly team pricing
One subscription, one shared credit pool, seats for your whole team. No per-quote negotiation.
You want a reseller-focused workflow
Synapse is built around resale: inspect, certify, and hand the buyer proof at the point of sale.
The certificate is the difference.
A wholesale platform tracks your inventory. A Synapse certificate lets your buyer verify a device before they pay.
From internal grade to buyer-facing proof
- Every certificate is server-issued and tamper-evident, so the result can’t be quietly edited after the fact.
- Buyers verify it from a scannable reference, with no login and no access to private data.
- A refunded purchase invalidates the certificate, keeping proof tied to a real sale.

NSYS alternative, answered
How Synapse compares for iPhone resellers.
Is Synapse an NSYS alternative?
Synapse is a focused alternative for resellers and refurbishers who want a 50-point iPhone inspection and a buyer-verifiable certificate, with team seats and a shared monthly credit pool. It centers on used-iPhone inspection and buyer trust rather than a broad wholesale catalog, so whether it fits depends on the workflow you need.
What does Synapse focus on?
Synapse focuses on refurbished-iPhone inspection and the certificate that comes out of it. The 50-point check runs on-device, and the result becomes a tamper-evident certificate your buyer can verify from a scannable reference — built around the moment a device changes hands.
Does Synapse cover a full wholesale ERP or grading platform?
No. Some teams run broad wholesale operations — multi-category inventory, large-scale grading, and order management — and those workflows may need additional systems. Synapse is deliberately focused on iPhone inspection and buyer-verifiable certificates, not a full enterprise ERP.
Can buyers verify a Synapse certificate without an account?
Yes. Every certificate is publicly verifiable through a scannable reference with no login. It shows non-PII device facts only — model, iOS version, capacity, pass and fail counts, inspection date, validity, and result.
How does team pricing work?
Synapse uses public monthly plans — Starter, Growth, and Scale — each with a set number of technician seats and certified checks that refill into one shared team pool every period. There is no quote process; you can see the plans and start when you are ready.
