Some freight has no business sitting on a rack — it's already prepped, already labeled, already late. ProShip3PL cross-docks Amazon-bound loads through our Medley, FL facility: unloaded, counted, condition-walked and label-sampled on the dock floor, then reloaded toward Amazon the same day or the next. Verification without the warehousing detour, for freight where the calendar is the whole point.
Plenty of Amazon-bound freight arrives finished. A factory that labels well, a seller who prepped upstream, a load that's pure replenishment for a starving listing — for these, racking the goods adds days and touches without adding safety. The put-away/pick cycle is pure friction when the destination was never in question.
What flow-through must never skip is the checkpoint itself. Freight that crosses our dock still gets counted against its paperwork, walked for transit damage, and sampled for label accuracy — because a bad load moving fast just fails faster at Amazon. The 2026 reality sharpens this: Amazon no longer fixes prep or labeling on arrival, so the last set of eyes before the FC is the only set.
Our position does half the work. Medley sits minutes from MIA's air cargo aprons and under an hour from PortMiami's drayage lanes, with Amazon's MIA1 facility about twelve minutes away — geography that makes a morning arrival and an evening outbound a routine day, not a heroic one.
| Question about the load | Cross-dock answer |
|---|---|
| Is all of it going to Amazon now? | Yes → flow through; No → split, balance goes to storage |
| Is it already prepped & labeled? | Verified by sampling; failures divert to the prep line |
| What gets checked on the floor? | Piece count vs paperwork, damage walk, label scan sample |
| How long does it stay? | Hours on a booked slot; next business day otherwise |
| What leaves the dock? | Amazon-compliant pallets or SPD cartons, on the first outbound leg |
Release-day stock with a calendar attached — verified and moving toward Amazon the day it lands, because the launch won't reschedule.
Freight racing a listing that's about to go dark — every rack-night skipped is a sales-day saved.
Goods finished upstream — bags, FNSKUs, cartons all done — needing only a US verification touch and a compliant handoff.
Mixed loads split by destination shipment on the dock floor — no put-away, just sorted lanes feeding separate outbound movements.
MIA freight cleared in the morning can be verified here midday and staged outbound by evening — the fastest lane we run.
The now-quantity crosses the dock immediately; the wait-quantity racks as reserve — one delivery, two speeds, your split.
Truck hits the booked window; floor space, crew and often the outbound leg are already assigned.
Piece count against paperwork, damage walk with photos, sample scans of FNSKU and carton labels.
Freight sorted by destination; exceptions divert to prep; pallets rebuilt to Amazon inbound rules where needed.
Clean freight stages outbound and leaves on the first available movement — same day on schedule, next day at worst.
Then it never touches a rack. We verify by sampling, rebuild pallets where required, and put it on the first outbound leg — a checkpoint measured in hours, not a warehouse stay.
Book the Wednesday morning slot now. Verification runs at arrival, the load stages outbound the same afternoon, and the peak window stays yours.
Use our dock as the seam: the forwarder delivers on normal commercial terms, and the freight leaves through the standard Amazon inbound flow with the appointment handled on our side.
That's cross-docking in one sentence. Count, condition, labels — verified in hours, reported the same day, and the load keeps moving unless something is actually wrong.
Cross-docking is flow-through handling: freight comes off an inbound truck, gets verified on the dock floor, and reloads onto an outbound movement toward Amazon without ever being put away into racking. It exists for goods that are already sale-ready — pre-prepped, pre-labeled, correctly cartoned — where the only jobs left are verification, sortation and a compliant handoff to Amazon's inbound network.
The target is same day for freight that arrives on a booked morning slot with paperwork in order, and next business day for afternoon arrivals or loads that need re-sorting. What actually sets the pace is carrier pickup availability and, for LTL, the Amazon appointment — we stage the freight outbound-ready and hand it off on the first available movement.
Speed doesn't mean blind. Every cross-dock load gets a carton or pallet count against its paperwork, a condition walk for transit damage, and a sample scan of FNSKU and carton labels to confirm they're present and readable. What we skip is unit-by-unit opening and full prep — that's the trade that buys the speed, and it only works because the freight was finished before it shipped.
Cross-dock wins when all the freight is going to Amazon now: a launch with a date, replenishment for a listing that's nearly out of stock, seasonal goods already late, or a factory-prepped load that just needs a US handoff. Storage wins when quantities exceed what Amazon should receive at once, or when you want a reserve to draw down over time — that model lives on our inventory storage page.
Yes — that's the ideal cross-dock cargo. If your factory or previous 3PL already applied FNSKU labels, poly bags and carton labels, we verify by sampling rather than redoing the work, rebuild pallets where Amazon's inbound rules require it, and move the load onward. If sampling reveals a labeling problem, the affected portion diverts to the prep line and the clean balance keeps moving.
Both. Palletized loads flow dock-to-dock with counts and a condition walk, then move out as LTL. Carton-level freight — air shipments, parcel batches, LCL boxes — gets sorted by destination shipment on the floor and leaves as small parcel delivery or gets consolidated onto outbound pallets, whichever the shipment plan calls for.
The load splits. Freight that passes keeps its same-day or next-day pace; the exception portion — damaged cartons, unreadable labels, a count that doesn't match — is photographed, reported to you immediately, and either fixed on the prep line or held for your decision. A problem in one tenth of the load shouldn't cost the other nine tenths their schedule.
For same-day flow-through, yes — a booked morning arrival is what lets us have floor space, a crew and often the outbound leg arranged before the truck arrives. Send the carrier, piece count and paperwork the day before. Unbooked freight still cross-docks, but it joins the queue and usually rides the next-day pace instead.
Yes, and hybrid flows are common: the quantity Amazon should receive now crosses the dock immediately, while the balance racks as reserve for later replenishment. You decide the split when you book the load — or after our dock counts confirm what actually arrived — and each portion follows its own path from the same delivery.
Send the form with the shape of the load — pallets or cartons, piece count, how it arrives, whether it's already prepped, and the deadline you're working against. Flow-through pricing comes back within one business day, per pallet or per carton, with no setup fee and no minimum.
Tell us what's coming — pallets or cartons, arrival date, prep status, and the deadline behind it all. Flow-through pricing and a confirmed dock plan come back within one business day.
