24-36 hours prep · FastLane 35H or the prep is free · Net-30 terms

Amazon SPN Certified · 5,500 sq ft, 3 dock doors · English, Spanish, Portuguese

PrepVia is the Amazon 3PL for wholesalers, brands, aggregators and agencies moving 1,000 to 40,000 units a month into FBA: pallets, case packs, containers and multi-account operations on one dock in Miami. Amazon inbound is the core product, not an add-on behind a DTC minimum. The best month on this dock moved 63,600 units; the peak week, 18,080 units in 15 shipments. If you ship fewer than 500 units a month, the Amazon FBA prep center page is the better fit.

What is a 3PL for Amazon sellers?

A 3PL for Amazon sellers is a third-party logistics warehouse that takes inventory from your supplier, your container or your own stock, makes it Amazon-compliant, and moves it into FBA. It receives freight, counts cartons, labels units and cases, builds pallets, creates the shipment in Seller Central, books the carrier, stores what should wait, and reports each step. Fulfillment by Amazon then stores and ships to the customer.

A prep center covers the middle of that list: labels, bags, boxes. The difference shows up at the first pallet, the first container, the first case pack that needs a carton label, and the first month with three accounts on the same dock. Those are the jobs a 3PL is organized around.

PrepVia runs both workflows in one building in Miami: the Amazon FBA prep center for parcel volume and the 3PL workflow on this page for pallets, containers, wholesale case packs and multi-account operations, with the same 24-36 hours prep window and the same FastLane 35H guarantee.

When does an Amazon seller need a 3PL?

Four signs, each one measured on our own dock.

You ship pallets, not parcels

Most of the freight that leaves this dock is LTL or FTL on Amazon partnered carriers. A prep center built around UPS boxes slows down at the first pallet.

You send case quantities and master cartons

Wholesale and distributor inventory arrives in case packs that need carton labels, pallet labels and a packing list that matches what Amazon receives. That is 3PL work, not label work.

Your inventory arrives in a container

Container receiving from $400 per container, with counts against the packing list on the dock. Floor-loaded containers are quoted by carton count before the truck arrives.

You run more than one account or brand

Aggregators and agencies need one dock, one workflow and one invoice per brand. The PrepVia app keeps each account separate while the floor runs as one operation.

How does PrepVia handle 3PL and FBA prep work in one dock?

Receiving to Amazon receiving status, with the count carried through every step.

Receiving with real counts

Every carton is counted against the packing list and the BOL, not booked as said-to-contain. Discrepancies are reported with evidence within 24 hours of arrival.

Case pack, carton and pallet labeling

Case pack labels, FBA box labels, pallet labels and FNSKU labels at up to 13,200 labels per hour, scan-verified with 2D barcodes.

Prep and compliance

Poly bagging, shrink wrap, bubble wrap, suffocation warnings, expiration labeling and Amazon packaging rules applied per ASIN, so a label error does not become an inbound defect fee.

Kitting and bundling at volume

Multi-packs from 2 to 24 units and custom kits built on the same dock, with the kit's own barcode applied and the Amazon prep requirement checked before it ships.

Shipment creation through our own API

PrepVia creates the Amazon shipment through its own SP-API integration, chooses the placement option, books Amazon partnered freight and produces the BOL. No copy and paste in Seller Central.

LTL, FTL and SPD on Amazon partnered carriers

Freight is bought on Amazon's partnered program at Amazon's negotiated rates and billed to your seller account. Under Amazon's terms you stay the shipper of record, and a carton lost on the way is claimed under the FBA reimbursement policy for shipments to Amazon. Departure and receiving status are visible in the app.

Storage billed by the day

Inventory can wait at PrepVia and drip-feed into Amazon on your schedule. Storage is billed daily, not on the peak of the month.

Removals and returns receiving

Removal orders and returns are received, inspected and put back into a sellable shipment or held, with the count reported per SKU.

Accountability

How does PrepVia prove custody of your inventory?

The question a wholesale buyer asks is not the price of a label. It is who takes responsibility when Amazon receives fewer units than the packing list said. PrepVia answers with four records instead of an apology.

Receiving count. Cartons and units counted against the packing list and the BOL on the dock, with discrepancies reported within 24 hours.
Scan-verified labels. Every FNSKU and box label is verified by 2D barcode scan before the carton closes, which is where the 99.9% accuracy figure comes from.
Box content and BOL. Box content information goes to Amazon through the API, and the bill of lading and proof of delivery are stored with the shipment.
Amazon partnered carrier. Freight moves at Amazon's negotiated rates, billed to your seller account, and on small parcel the tracking a reimbursement claim needs is recorded in the shipment automatically.

How the paper trail works when a shipment is short: BOL, POD and the FBA paper trail.

Measured, not promised

What do the production numbers say?

Measured in the PrepVia app and verified on September 23, 2026. Fastical volume as reported by the founder.

Measure	Verified September 23, 2026
Best month on the dock	63,600 units
Peak week	18,080 units in 15 shipments
Median hours, shipment created to carrier pickup	30.2
Fastical, one client, in one year	350,000 units
Fastical, in one month	32,000 units

Median hours are counted from the moment the shipment is created in the app to the carrier pickup scan. Fastical volume is reported by the founder; the rest is measured in the app.

Where each option fits

PrepVia vs a national 3PL network vs Amazon AWD

Three different products. A national network is the right call for a DTC-first brand that needs inventory in several regions; AWD is right for standard-size goods you never need to touch again. This is what PrepVia is for.

Question	PrepVia, Miami	National 3PL network	Amazon AWD
Core product	Amazon FBA inbound, first	DTC fulfillment, with FBA prep as an add-on or a minimum	Amazon storage feeding FBA
Check-in guarantee	35 hours or the prep is free (FastLane 35H)	Turnaround targets, rarely with a penalty	Amazon controls timing
Where your inventory sits	One dock in Miami, visible in the app	Split across a network by their allocation rules	Inside Amazon's network
Freight to Amazon	Amazon partnered LTL, FTL and SPD, booked by our API	Own carriers or partnered, depends on the site	Amazon moves it
Payment terms	Net-30, no credit check	Prepay, card on file or deposit	Charged to the seller account
Container receiving	from $400 per container	Quoted per site	By dock appointment, closed boxes only; Amazon writes a floor-load rule only for its West Coast Palletizable region, where it palletizes imports
Best fit	Wholesalers, brands, aggregators and agencies shipping into FBA from the Southeast or through Miami ports	Brands whose main channel is DTC across regions	Standard-size goods you never need to touch again

Integrations

Which channels and integrations does PrepVia support?

Amazon, natively. PrepVia is an Amazon SP-API authorized partner. The app creates inbound plans, chooses the placement option, submits box content, books partnered freight and polls receiving status through the API. You approve; nobody retypes anything in Seller Central.

Other channels. Walmart WFS prep and TikTok Shop prep run on the same dock with the channel's own label and packaging rules. Shopify connects through the PrepVia app for order and inventory data. eBay, Etsy and wholesale outbound are handled as B2B shipments with pallet labels and a packing list.

What is not offered. EDI and ASN transactions to retailers, and lot-level recall tracking inside a WMS. If your program needs them, we will tell you before you ship a carton.

Questions a 3PL buyer asks

What is the difference between a 3PL and a prep center for Amazon sellers?

A prep center labels and bags units and hands them to a carrier. A 3PL for Amazon sellers also receives freight and containers, counts cartons against the packing list, builds pallets, books partnered freight, stores inventory and reports on every step. PrepVia runs both on the same dock in Miami: the prep center workflow for parcel volume and the 3PL workflow for pallets, containers and multi-account operations.

Does PrepVia count every carton or book inventory as said-to-contain?

Every carton is counted against the packing list and the BOL at receiving. Discrepancies are reported with photos within 24 hours of arrival. Amazon then receives what left our dock, and the two counts can be reconciled line by line in the PrepVia app.

What happens if the 35-hour check-in guarantee is missed?

The prep is free for that shipment. FastLane 35H measures the time from PrepVia check-in to Amazon delivered status on eligible workflows: shipments up to 40,000 units to eligible fulfillment centers in Florida, North Carolina, Georgia and Alabama, created before arrival with 3 days of notice. The full terms are on the SLA guarantee page.

Do you use Amazon partnered carriers, and why does it matter?

Yes. LTL, FTL and small parcel shipments are booked on Amazon's partnered carrier program through our own API integration, at Amazon's negotiated rates billed to your seller account. Under Amazon's partnered carrier terms you remain the shipper of record and keep title and risk of loss, and Amazon is the payer of record. A carton lost on the way is claimed under Amazon's FBA reimbursement policy for shipments to Amazon, which asks for proof of ownership and proof of delivery. On small parcel, the partnered program records the tracking in the shipment; with your own carrier you must enter the tracking ID before Amazon can reimburse.

How is storage billed?

By the day, on the space actually used, at the rate published on the pricing page. There is no charge on the peak inventory level of the month, so drip-feeding Amazon from PrepVia does not cost more than sending everything at once.

Do you support EDI, retailer routing guides or Vendor Central?

No. PrepVia does not run EDI or ASN transactions today. What we do for wholesale accounts is case pack labeling, master cartons, pallet building, LTL and FTL to Amazon, and box content information through the Amazon API. If your program requires EDI to a retailer, we say so up front instead of learning it on the dock.

Can you handle hazmat, batteries and expiration-dated products?

Expiration-dated products are labeled with the expiration date and shipped inside Amazon's window. Products with lithium batteries or other dangerous goods need Amazon's hazmat approval on the listing before they can enter an FBA shipment; PrepVia checks the listing status before receiving so the units do not sit in review at the warehouse. Lot-level recall tracking inside a WMS is not a service we offer today.

Is there sales tax on prep, and does Florida inventory create nexus?

PrepVia does not charge sales tax on prep and fulfillment services in Florida, and no resale certificate is needed for that. Whether inventory stored in Florida creates a sales tax obligation for your company is a separate question that depends on your registrations and on marketplace facilitator rules; we point you to your accountant rather than answer it on a services page.

How do I request a rate card or get an RFP answered?

Send the SKU count, monthly units, cartons or pallets per inbound and your channels through the contact page or by email, and you receive a rate card for your volume level and a sample invoice. Company facts for an RFP (address, hours, certification, SLA definition, payment terms, published prices) are on the PrepVia facts page.
