3PL for Amazon Aggregators: One Dock, Many Brands
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 3PL for Amazon aggregators: portfolios of 3 to 30 brands, each with its own Seller Central account. Every brand gets its own account in the PrepVia app, its own report and its own invoice. The floor runs as one operation: one dock in Miami, one team, one workflow. The best month on this dock moved 63,600 units; the peak week, 18,080 units in 15 shipments, across every account. This page covers the portfolio workflow; the 3PL prep center for Amazon sellers page covers every segment.

What does an aggregator need from a 3PL that a single brand does not?
Six requirements that show up in every aggregator RFP, and how each one is met on the floor.
One Seller Central account per brand
Each acquired brand keeps its own Seller Central account, its own FNSKUs and its own inbound history. The 3PL has to work inside every account without mixing them.
A report per brand
The portfolio team reads receiving, prep and shipment status per brand, not one blended number. Each brand P&L needs its own line for logistics.
One invoice per brand
Prep, storage and freight are billed per brand account. The cost of goods for each brand stays clean for the next valuation or exit.
An SOP per brand
Prep rules, expiration rules and packaging differ from brand to brand. The SOP lives in the brand account, not in one operator's memory.
Removals and relabeling at every acquisition
An acquired brand often arrives as a removal order from the seller's old account. Units are received, inspected and relabeled to the new FNSKU before re-inbound.
Inventory transfer when a brand is sold
When a brand leaves the portfolio, its inventory is counted and relabeled if the FNSKU changes. It ships or is handed over with a receiving report.
Brands that ship case packs and pallets have their own page: wholesale FBA prep at volume.
How does PrepVia keep accounts separate on one floor?
The PrepVia app holds one account per brand. Each account has its own Amazon connection, its own inventory, its own shipments and its own invoice. The founder and the team operate every account from the same floor. The workflow does not change from brand to brand.
Cartons are received into the brand account on its packing list. A carton that belongs to one brand cannot be placed in a shipment for another. The app shows only the account's own SKUs when a shipment is built.
Box content, BOL and receiving status are stored per shipment inside the account. Your portfolio team can open any brand and see the same records the operator sees.
| What stays separate | How |
|---|---|
| Amazon connection | One Seller Central connection per PrepVia account, authorized from the brand account itself. Shipments are created through our own SP-API integration inside that account. |
| Inventory and SKUs | Received into the brand account against its own packing list. When a shipment is built, the app shows only that account's SKUs. |
| Shipments, BOL and receiving status | Stored per shipment inside the account. Box content goes to Amazon through the API and receiving status is polled until Amazon closes the shipment. |
| Invoice | One invoice per brand account: prep per unit, storage by the day, freight as booked on Amazon's partnered program. |
| Prep SOP | Prep rules, expiration rules and packaging notes per SKU, stored in the account. Whoever is on the line that day applies them. |
| Visibility | Your portfolio team opens any brand account and sees the same records the operator sees: counts, labels, shipments, invoices. |
How do removals, returns and relabeling work when you acquire a brand?
The inventory of an acquired brand usually sits in the seller's old account. Four steps move it to yours.
Removal order to PrepVia
Create the removal order to the PrepVia address from the brand account. Cartons arrive with the removal order ID and are counted against it.
Inspection per unit
Units are inspected and sorted: sellable, damaged, wrong item. The count per SKU and per condition goes into the account.
FNSKU relabel when the SKU changes account
When a listing moves to a new Seller Central account, the FNSKU changes. Old labels are removed or covered and the new FNSKU is scan-verified.
Re-inbound
Sellable units go back into an FBA shipment created through the API in the new account, on Amazon partnered freight.
Customer returns follow the same inspection step. Removal order fees, timelines and the disposition options are in the Amazon removal orders guide.
How does onboarding a new brand work?
Same day, no setup fee, and a test shipment before the volume moves.
Connect the account
Same day. The brand's Seller Central account is connected to its own PrepVia account. There is no setup fee.
Load the SOP
Prep rules, expiration rules and packaging notes per SKU go into the account before the first carton arrives.
Test shipment
Send 200 to 500 units first. You see the receiving report, the labels, the shipment in Seller Central and the invoice.
Move the volume
Then move the brand's inbound flow. The next brand in the portfolio follows the same four steps.

What is measured?
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.
What does the portfolio team get when a shipment is short?
Four records per brand account, instead of an email chain across brands.
- Receiving count. Cartons and units counted against the packing list and the BOL on the dock. Discrepancies are reported with photos within 24 hours of arrival.
- Scan-verified labels. Every FNSKU and box label is verified by 2D barcode scan before the carton closes. That scan is where the 99.9% accuracy figure comes from.
- Box content and BOL. Box content goes to Amazon through the API. The bill of lading and the proof of delivery are stored with the shipment.
- Amazon partnered carrier. Freight moves under Amazon's carrier program. A carton lost after pickup is an Amazon reimbursement case, not a dispute with a trucker.

Can we export our data without asking support?
Do you use Amazon partnered carriers, and does that matter for reimbursement?
What are the contract terms, and how do we exit with a brand?
Do you run EDI or retailer routing guides?
Send the brand list, the SKU count per brand and the monthly units. The rate card comes back with a sample invoice.
