PrepVia: Best Overall Amazon FBA Prep Center, and the Tools Behind It

By Bernardo Campelo, Founder of PrepVia

Short answer: we call PrepVia the best overall Amazon FBA prep center because it is strongest on the three things that decide how fast your inventory goes live and how much work you do to get it there: speed, software and logistics. This post shows the tools and the numbers behind that claim, with dates, and the two places where PrepVia is weaker. Disclosure: I founded PrepVia, so check everything below instead of taking my word for it.

The criteria come from our guide, How to Choose the Best Amazon FBA Prep Center, which applies the same six criteria to ten prep centers.

The Software: What the PrepVia App Does

Most prep centers run on email threads and spreadsheets. PrepVia runs on its own app and its own Amazon integration, so the work a seller usually does by hand happens in the system.

• Amazon SP-API integration, built in-house. PrepVia is an Amazon SP-API authorized partner. The integration creates inbound plans, picks placement options, sends box content, books Amazon partnered freight and reads receiving status back from Amazon.
• Shipments without spreadsheets. After a one-time setup, a shipment is created and dispatched through our own Amazon integration, with no FNSKU spreadsheets or manual box counts.
• AI shipment creation and inventory import. Describe the shipment you need and the app builds it; add products with AI instead of typing them in.
• Bulk inbound creation. Create inbounds by SKU or by pack configuration, with a manual option when you need it.
• Real-time tracking. Expected versus received units, discrepancy alerts and a status timeline for every shipment.
• Pre-Fulfillment Requests. Define the outbound plan while you create the inbound, so eligible shipments move as soon as the freight lands.
• Billing and accounting. Daily storage visibility, invoices and QuickBooks sync.
• Shopify. The PrepVia app is listed on the Shopify App Store for direct-to-consumer orders.
• One account per brand. Agencies and aggregators see each client on its own.

The full feature list is on the PrepVia app page, and the app comes free with every account.

The Floor: Equipment and Throughput

• Up to 13,200 labels/hour on the automated labeling line, 99.9% scan-verified.
• A multipack line at about 120 packs per minute.
• Peak week on our dock: 18,080 units in 15 shipments, measured in our app and verified on September 23, 2026.

Speed: Guaranteed End to End, and Measured

• Standard prep window: 24 to 36 hours.
• FastLane 35H: 35 hours from check-in at our dock to Amazon FBA delivered status, or the prep is free. The terms are on the SLA guarantee page.
• Median 30.2 hours from shipment created to carrier pickup, measured in our app and verified on September 23, 2026.

Most prep centers quote a prep SLA, where the clock starts when they begin work. FastLane's clock starts when your freight checks in and stops when Amazon marks it delivered, so queue time, shipment creation and transit all sit inside it.

Logistics: Built for Freight Landing in South Florida

• Our dock is at 8507 NW 72nd St, Miami, FL 33166, in the Doral and Medley corridor, near PortMiami, Port Everglades and Miami International Airport.
• 5,500 sq ft with 3 dock doors. Containers come in floor-loaded or palletized.
• Freight leaves for Amazon by partnered LTL, FTL or small parcel. FastLane 35H: 35 hours end to end, from check-in at PrepVia to Amazon FBA delivered status, or the prep is free.
• Discrepancies are reported within 24 hours of arrival, with photos.
• Florida does not tax prep services, so there is no sales tax on prep.

Where PrepVia Is Weaker

• Pricing is not published. We quote each account on a free 15-minute call.
• A short public record. PrepVia was founded in 2025 and has 7 reviews on Clutch so far.
• Not offered: cold storage, an FDA-registered facility, EDI and ASN transactions, and lot-level recall tracking.

If those matter more to you than speed and software, another prep center in our comparison may fit you better.
