Our Story
We didn't learn logistics from a textbook. We learned it from late nights fixing shipment errors, fighting suspended listings, and missing holiday deadlines.
ThirdPartyPrep was founded by two partners who spent over a decade as eCommerce resellers, scaling their business to 8 figures in sales across every major marketplace — Amazon, Walmart, eBay, Shopify, and more.
We've dealt with every headache a seller can face: mislabeled FBA shipments that got stranded at Amazon warehouses, inventory discrepancies that cost us thousands, 3PLs that promised the world and delivered late shipments and zero communication. We lived the chaos.
After years of struggling to find a fulfillment partner who actually understood our business, we realized the partner we were looking for didn't exist. So we built it ourselves.
ThirdPartyPrep isn't just another warehouse with a website. It's the fulfillment company we wish we had when we were scaling our own operations — one that speaks your language, understands marketplace compliance inside and out, and treats your products like we're the ones selling them.
We built this company on a simple belief: entrepreneurs should spend their time building great products and growing their brand, not worrying about whether their orders shipped on time. You sell it. We handle the rest.
Every decision we make starts with one question: does this make life easier for the seller?
Amazon, Walmart, eBay — we know the compliance rules, the prep requirements, and the pitfalls.
We don't disappear after onboarding. Your dedicated account manager picks up the phone.
99.8% accuracy because we've been on the other side — we know what a wrong shipment costs you.
How It Works
Scroll to watch how we handle every step of your fulfillment.
Ship us your products — pallets, cases, or individual units. We unload, inspect, count, and store everything in our warehouse system.
When an order comes in, we pull the right products, assemble the box, and prep it for packing. Custom kitting and bundling handled here.
Your products are placed inside with protective materials, branded inserts, and any custom packaging you need. Quality checked before sealing.
Box is taped, labeled, and handed to the carrier. Real-time tracking flows back to your dashboard and your customer's inbox. Done.
