PrepVia is a prep center and 3PL in Miami for ecommerce brands that sell on more than one channel.
One inventory feeds your Amazon FBA shipments, your Shopify and eBay orders through the PrepVia app, and the Walmart, TikTok Shop, Etsy and WooCommerce orders you create in the app. The app runs on PrepVia's own Amazon SP-API integration: when you register an FBA inbound, it checks each item's eligibility and creates the FBA draft from the eligible ones. The best month on this dock moved 63,600 units, Fastical volume included; the peak week, 18,080 units in 15 shipments. For pallets, containers or case packs, the wholesale FBA prep at volume page is the better fit, and the 3PL for Amazon sellers page covers every segment.

What changes when a brand sells on more than one channel from one inventory?
Four things change on the dock. None of them should change the count.
One stock, different rules per channel
Amazon wants an FNSKU label on each unit and, for some products, a poly bag with a suffocation warning. Walmart WFS has its own carton labels, and TikTok Shop has its own checklist. The units come from the same stock, so the split happens on the dock, per SKU and per channel.
Cartons and parcels from the same shelf
FBA shipments leave in cartons. Shopify, eBay, Etsy and WooCommerce orders leave one parcel at a time. Both draw from the same inventory in Miami, and the PrepVia app shows what is at PrepVia and what is at Amazon.
Not every channel connects
Amazon, Shopify and eBay connect to the PrepVia app. Walmart, TikTok Shop, Etsy and WooCommerce orders are created in the app, by form or spreadsheet, with the label you upload. We say which is which before you connect anything.
A launch can empty the FBA stock
A promotion on one channel can use up the units the next FBA shipment needs, unless the stock at Amazon, on the way and at PrepVia sits side by side, per SKU.
The full workflow, channel by channel: multichannel prep for Amazon, Walmart and TikTok Shop.

How does a brand's stock move through PrepVia?
Through the same screens of the PrepVia app, from the supplier to Amazon and to your customers.
Step 1
Send to PrepVia
Choose where the stock goes next: Amazon FBA, storage for FBM, your Shopify or eBay orders, or another marketplace. Add the products from your inventory, a spreadsheet or the supplier's invoice.
Step 2
Shipment tracking
Expected against received units for each product, and a warehouse receipt in PDF once the inbound closes.
Step 3
Send to Amazon
Pick the units and write the prep notes. PrepVia builds the FBA shipment through the SP-API, picks the placement and books the freight, and you follow it until Amazon receives it.
Step 4
Orders
Shopify and eBay orders with your linked products come into the app. For Walmart, TikTok Shop, Etsy and WooCommerce, you create the order in Orders and upload the label.
No typing the supplier's invoice: with AI document reading, the AI reads it into a list of SKUs and quantities that you check before saving.

How does PrepVia protect packaging and brand standards?
The unboxing is the brand. Four controls keep it the same on every unit.
Prep notes on every request
Each FBA request carries your prep notes: a poly bag with a suffocation warning, an expiration date, an insert. Prep that follows your own instructions is a service of its own.
Counted at receiving
The PrepVia app shows expected against received units for each product, and a warehouse receipt in PDF once the shipment closes. A short count is on record before the units are prepped.
Kits, inserts and your boxes on the same dock
Multi-packs, bundles, inserts and branded boxes are built where the units are prepped. The kit gets its own barcode before it ships.
Labels checked by scan
Every FNSKU and box label is scanned to verify it before the carton closes.

How does a launch or a seasonal SKU get to Amazon fast?
Four steps, from the FBA draft to the stock that waits in Miami. The guarantee has a remedy; the median on this page is a measurement.
Step 1
The FBA draft before the units arrive
When you register the inbound for Amazon FBA in Send to PrepVia, the app checks each item's Amazon eligibility and creates the FBA draft from the eligible ones, so prep starts when the units land.
Step 2
Prep in 24-36 hours
Check-in, prep and closed cartons inside 24-36 hours on eligible workflows. FastLane 35H: 35 hours end to end, from check-in at PrepVia to Amazon FBA delivered status, or the prep is free.
Step 3
Freight to Amazon
SPD, LTL or FTL, booked on Amazon's partnered carriers when Amazon offers them for the placement.
Step 4
Drip-feed the rest
Launch stock that should wait stays at PrepVia, billed daily on the space it uses. Replenishment shipments go out on your schedule, not on a monthly peak.
The guarantee: FastLane 35H. At eligible fulfillment centers in Alabama, North Carolina and Georgia, FastLane Extended is 35 hours plus one day end to end or the prep is free. Eligibility, measurement and the remedy are written on the SLA guarantee page.
