Seller Case Studies

Real before-and-after results from sellers who made the switch.

Case Study 01 — Wholesale

From $8K to $40K/Month in 90 Days

A wholesale Amazon seller was losing 2–3 selling days per week waiting for their old prep center to process shipments. After switching to PSF, same-day and 24-hour processing unlocked consistent inventory flow. Combined with zero Amazon rejections and real-time PrepCorex tracking, the seller scaled their catalog from 12 ASINs to 47 within 3 months — growing monthly revenue 5x.

Case Study 02 — Private Label

Zero-Defect Launch — 500 Units, Day One

A private label brand launching their first product needed full QC inspection, insert placement, and launch-ready processing — all before their PPC campaign went live. PSF received 500 units from their Chinese manufacturer, performed full quality control, inserted branded cards, applied FNSKUs, and dispatched to Amazon FBA within 36 hours. The launch went live on time. No defects reached customers. First review: 5 stars.

Case Study 03 — Returns Recovery

$12,000 Recovered from Removal Orders

A high-volume FBA seller had accumulated 800+ units in removal orders they had written off as losses. PSF received, inspected, and categorized every unit. 73% were found to be fully sellable with new packaging and FNSKU re-application. The rest were routed through liquidation channels. Total cash recovery: over $12,000 from inventory the seller had already written off.

When They Switch to PSF

Real numbers. Real sellers. Real growth. See what happens when your prep center stops being a bottleneck and starts being a competitive advantage.

What Sellers Are Saying

From wholesale to private label to online arbitrage — real words from real sellers.

PSF turned our logistics nightmare into our competitive advantage. Same-day prep means we never miss a selling window. We've scaled from $8K to $40K/month since switching.

The PrepCorex dashboard alone is worth it. I can see exactly where every unit is, 24/7. No more spreadsheet chaos. No more chasing my prep center for updates. Complete peace of mind.

We switched from a cheaper prep center and immediately saw fewer rejections, faster check-ins, and happier customers. The price difference paid for itself in the first month.

As an OA seller, my suppliers ship directly to PSF. They sort, inspect, and get everything into Amazon within 48 hours. My IPI score has never been better. Absolutely game-changing.

I was nervous about expanding to Walmart WFS. PSF knew exactly what Walmart needed — labels, pallets, everything. My first WFS shipment was accepted with zero issues. Huge relief.

Our DTC brand needed branded unboxing — tissue paper, thank-you cards, the works. PSF handles it all without us having to explain twice. Our customer reviews mention the packaging constantly.

Case study FAQs

How to read these stories against your own numbers.

Are these guarantees?

No. Results depend on your SKUs, freight, and channel mix. Case snapshots show patterns we repeatedly deliver when workflows match the problem.

Can you share a relevant reference?

On the audit call we can discuss similar volume/channel profiles and the operating plan we would use for you.

Do you publish fake “0 sellers / 1 hour” counters?

No. We use honest metrics — turnaround targets, channel coverage, and NJ positioning — not broken Elementor counters.
