FBA handles your customer's doorstep. Everything before it — supplier freight, inspection, prep, reserve stock, replenishment timing, returns, and the orders you sell off-Amazon — is yours to run. ProShip3PL is that layer: a Miami 3PL where one inventory pool feeds FBA on demand and ships Shopify, eBay and FBM orders on the side.
Amazon's fulfillment network is superb at one thing: getting a sold unit to a buyer fast. It is indifferent to everything upstream. It won't inspect your factory's work, won't hold your overflow economically, won't time your replenishments, and treats returned units as a disposal problem rather than an asset.
Growing sellers discover this the expensive way: a container that has nowhere to go, capacity limits that cap a Q4, removal orders binned because nobody could receive them, and a Shopify store that needs its own separate stock. Each gap gets patched with another vendor — until the patchwork itself is the problem.
The 3PL model closes those gaps in one place. Your inventory lives on our racks in Medley, FL as a single pool. From it, FBA gets fed exactly what velocity demands; direct orders ship to buyers same-day; removals return, get graded and re-enter the pool. One dock, one system of record, one phone number.
| Upstream gap | How the 3PL layer fills it |
|---|---|
| Supplier freight has no destination | Our dock receives parcel through full container, counted same day |
| Nobody checks factory quality | Arrival inspection with photos — before Amazon sees a unit |
| Overflow has nowhere economical to sit | Reserve racks, billed only for space actually used |
| Replenishment timing is guesswork | Trigger-based shipments, 24–48h from signal to carrier |
| Returns die in removal orders | Graded, recovered, relabeled, re-pooled |
| Off-Amazon orders need their own stock | Same pool ships Shopify, eBay, Etsy, Walmart, FBM |
Supplier cartons, pallets and containers checked in against POs with same-day discrepancy and damage reporting.
The full prep stack — covered in depth on our prep services page — feeding shipments that check in clean.
Bin and pallet storage for stock Amazon shouldn't hold yet — the buffer that beats capacity limits and storage-fee math.
Standing triggers or on-demand calls move reserve stock into Amazon in sales-sized batches, 24–48h from signal to carrier.
Removal orders graded unit by unit; the sellable share relabeled and recovered instead of written off.
Shopify, eBay, Etsy, Walmart and FBM orders picked, packed and shipped from the same pool that feeds FBA.
| Your situation | Prep service is enough | You need the 3PL layer |
|---|---|---|
| Inventory flow | Straight line: supplier → prep → FBA | Stock must wait, split, or return somewhere |
| Channels | Amazon only | Amazon + Shopify/eBay/Walmart/FBM |
| Buying pattern | Order what FBA can absorb now | Container-sized buys, seasonal positions |
| Returns volume | Low enough to ignore | High enough that recovery is real money |
| Amazon capacity limits | Rarely bind you | Regularly cap your inbound |
Both run on the same floor here, so the answer can change with your business — start with prep, and the fuller layer is one conversation away, not a vendor migration.
Your production run or wholesale buy arrives — counted, inspected, reported, racked as reserve.
Replenishment triggers fire as stock sells; prepped batches flow into Amazon in tune with velocity.
Shopify, eBay and FBM orders pick from the same pool and reach buyers without touching FBA.
Removals come home, get graded, and sellable units rejoin the pool for the next cycle.
Everything around FBA that Amazon doesn't do for you: receiving supplier freight, quality inspection, prep and labeling, holding reserve inventory, replenishing FBA on schedule, recovering removal orders, and shipping the orders you sell outside Amazon. FBA covers the last mile to the customer; a 3PL covers everything before and beside it.
Prep alone fits sellers whose whole business is a straight line: supplier to Amazon. You need the fuller 3PL layer when inventory has to wait somewhere (capacity limits, seasonal buys, container arrivals), when you sell on more channels than Amazon, or when returns and removals are big enough to be worth recovering rather than writing off.
Yes — that's the core 3PL advantage. Your stock sits on our racks as one pool: part flows into FBA as replenishment, part ships direct to buyers from Shopify, eBay, Etsy, Walmart or FBM orders. No more guessing how to split a production run between channels months in advance.
You set the trigger — a reorder point in Seller Central, a weekly cadence, or an email saying "send 500 of SKU X." We pick the units from reserve, prep anything not yet prepped, build the shipment with box-content data, and hand it to the carrier — usually within 24–48 hours of the trigger.
Yes. Removal orders arrive at our dock, each unit is inspected and graded — sellable, repairable, or dispose — and you get a report. Sellable stock is relabeled and returned to FBA or folded into your reserve pool; the rest is held or disposed of on your instruction. Recovered units are pure margin you'd otherwise lose.
That's one of the most valuable plays: when FBA inventory strands or runs out, you flip listings to FBM and we ship those orders from your reserve stock the same or next business day. Sales continue while the FBA pipeline recovers — instead of your listing going dark and losing rank.
You get receiving confirmations with counts, discrepancy and damage reports with photos, and stock updates as inventory moves between reserve, prep and outbound. You always know what's on our racks versus what's inside Amazon — ask us to walk you through the reporting flow on a call.
Yes. You work with a named contact who knows your SKUs and standing instructions — reachable by phone, email and WhatsApp. Operational questions get answered by someone who can walk to your pallets, not by a ticket queue.
Most clients do. A typical path: start with prep on one shipment, add reserve storage when the first container lands, add replenishment when Amazon capacity tightens, add FBM and multi-channel when the brand grows. Services are per-unit and modular — you're never paying for the full stack before you need it.
