Stockouts kill rank; overstock pays Amazon rent. The replenishment operation lives between those failures: a written trigger per SKU, shipments sized to weeks of cover, and a warehouse that turns each trigger into a carrier hand-off inside 24–48 hours — from Medley, twelve minutes from Amazon MIA1. Your listings run lean because the response loop is short enough to allow it.
Every seller has felt both failure modes. The stockout: a bestseller goes dark for nine days, the rank you spent months building bleeds away, and the relaunch spend exceeds whatever the missed sales cost. The overcorrection: next time you ship six months of units, and the settlement report spends a year reminding you where they're sitting.
Both are symptoms of one flaw — a reaction loop too long for the decision it serves. If restocking FBA means calling a factory, you must guess far ahead, and far-ahead guesses are big and wrong. Shrink the loop to two days and the guesses shrink with it.
That two-day loop is the service. Your restock stock sits ready in our building — the racking economics live on our inventory storage page — and a trigger you define starts the motion: pick, complete any remaining prep, case-pack with box content information, book, load. The carrier has it inside 24–48 hours, and Amazon MIA1 is a twelve-minute drive from the dock.
The craft is in the sizing and the calendar: shipments matched to sell-through, reorder points that respect Amazon's check-in delays, and a cadence that tightens before Q4 and relaxes after — all written down, so restocking stops being an act of memory.
| Replenishment lever | How it's set |
|---|---|
| Trigger | Reorder point per SKU, fixed cadence, or your manual call — documented either way |
| Shipment size | Target weeks of cover against current velocity, revised as velocity moves |
| Response time | 24–48 hours from trigger to carrier hand-off |
| Seasonal cadence | Front-load before peak, tighten during, unwind after |
| Multi-SKU logic | Near-trigger SKUs ride along, resetting several clocks per pickup |
Per-SKU trigger levels built from your velocity plus realistic check-in delay — reviewed when sales pace shifts, not set once and forgotten.
Weeks-of-cover targets translated into unit counts and cartons — enough to protect rank, little enough to keep Amazon's meter quiet.
Pick from reserve, close out prep, case-pack with box content data, book the carrier — the 24–48 hour window covers all of it.
SKUs approaching their trigger join the outbound shipment, so one pickup services several listings instead of one.
Front-loading before receiving slows, tightened triggers through the season, and hand-off dates tracked against Amazon's holiday cutoffs.
Where you hand us reorder points, we prompt you as levels approach them — the restock decision becomes a reply, not a monitoring shift.
A reorder point crosses, a cadence date arrives, or your email lands — the shipment plan opens the same day.
Units come off reserve racking; any labeling or bagging still owed gets closed out on the bench.
Case-packed cartons with box content information, shipment created in your account's flow, carrier booked.
Boxes leave the dock — with MIA1 twelve minutes away, the transit leg is the shortest part of the story.
The fix is structural, not motivational: a written reorder point that accounts for check-in delay, and a warehouse that answers it in two days instead of when someone gets around to it.
Big shipments are what long reaction loops force. Shorten the loop through our dock and the same safety comes from frequency, at a fraction of the parked inventory.
Both are calendar failures. We front-load while receiving is fast, tighten triggers through the season, and taper the last shipments so the New Year doesn't inherit a mountain.
If the system is your memory, it fails when you rest. Written triggers plus our level alerts mean the loop keeps turning while you're off the grid.
Anything unambiguous. Some clients set a reorder point per SKU — when FBA sellable units cross it, we build the next shipment. Others run a fixed weekly or biweekly cadence, and a few just email a SKU list when their dashboard turns yellow. The trigger style matters less than having one written down; drift starts when replenishment depends on someone remembering.
Trigger to carrier hand-off runs 24–48 hours. The speed comes from preparation, not heroics: reserve units are already received and inspected, most SKUs are pre-prepped, and the shipment plan template for your account exists before the trigger fires. What remains on the day is pick, finish prep, case-pack, book and load.
Match the shipment to sell-through, not to what fits on a pallet. The working question is weeks of cover: if a SKU sells 300 a week and lead time to being sellable in FBA is two weeks, a shipment far below 600 flirts with a stockout while one triple that just pre-pays Amazon storage. You set the target cover; we size and adjust the shipments as your velocity moves.
By shortening the reaction loop. When restocking means a supplier PO, your correction horizon is months and you over-order to be safe. When restocking means a trigger to a warehouse twelve minutes from Amazon MIA1, the horizon is days — so FBA can run lean and mistakes in either direction cost little. Small, frequent, boring shipments are the whole trick.
Earlier, then faster. Ahead of the season we front-load FBA while Amazon's receiving is still quick, because check-in times stretch badly as peak builds. Once the season runs, triggers tighten — weekly SKUs go twice-weekly, reorder points rise to cover receiving delay, and we watch hand-off dates against Amazon's holiday inbound cutoffs. In January the cadence relaxes again so leftover stock doesn't pile up inside the network.
The account stays yours, so Seller Central visibility is yours — but you choose how automatic the loop gets. Hands-on clients send us each trigger themselves. Others hand us agreed reorder points per SKU and we prompt them when a level is crossed, so the decision is a one-word confirmation instead of a monitoring chore.
Yes, and it usually should. When one SKU trips its trigger we check what else is within a week or two of tripping and propose topping those up in the same shipment — one carrier pickup, one check-in, several stockout clocks reset. Case-packing and box content information keep multi-SKU shipments clean on Amazon's receiving end.
Your choice, and it's a real trade. Prepping at intake makes the outbound day pure pick-and-ship — fastest possible trigger response. Prepping at replenishment keeps units in their original state, which preserves options if you might redirect stock to another channel or change the labeling. Many accounts split it: stable SKUs pre-prepped, undecided ones prepped on the way out.
On bins and pallet racking in our Medley warehouse, billed monthly on space used — the economics, formats and capacity-limit logic of holding stock outside Amazon are covered on our inventory storage page. This page is about the motion; that one is about the parking. The two run on the same floor, which is why the loop is fast.
Send the form with your SKU count, current weekly velocity on your main sellers, and how you'd like to trigger — reorder points, fixed cadence, or manual. Within one business day you'll get per-unit pricing and a proposed replenishment rhythm; from there your first inbound to us starts the loop. No setup fees and no monthly minimums.
Tell us your SKU count, rough weekly velocity, and how you'd like triggers to work. Within one business day you'll have per-unit pricing and a proposed cadence — and your listings stop depending on anyone's memory.
