Executive TLDR

FBA limits and changing seller rules can choke growth if you rely on Amazon for everything.
Keep one clean inventory pool, use a central Midwest hub, and blend FBA for top movers with 3PL and SFP for the rest.
Improve acceptance with tight prep and labeling, right size packaging, and accurate ASNs so units flow in without refusals.
Reduce storage pressure by aging out slow movers, kitting smart, and sending only what sells in the next 30 to 45 days.
Measure a few numbers daily, inbounds accepted on first try, aged units, sell through, and billable weight.

What FBA limits really do

FBA storage and restock caps are guardrails, not a wall. They push you to send leaner, faster turning inventory and penalize aging product. If you send sloppy inbounds or park long tail units in FBA, you pay more and move less. The fix is a simple plan. Keep one inventory pool in your control, feed FBA with the winners, and ship the rest through a fast 3PL path.

The better inventory model

One pool, many paths
Keep inventory centralized in the Midwest for national ground reach in 1 to 3 days. Route orders by promise and cost. Use:

FBA for proven top movers that sell through quickly.
Seller Fulfilled Prime or MFN via a 3PL for the long tail and bundles. See 3PL fulfillment and ecommerce fulfillment services.
Periodic feeds to FBA driven by real sell through, not guesses.

This avoids duplicated safety stock and keeps storage fees predictable.

Get accepted on the first try

Most FBA pain starts before the truck leaves your dock. Tighten the inputs.

FNSKU discipline
One scannable code per sellable unit. Lock label placement templates for units, inners, cartons, and pallets.
Prep and packaging rules
Define by family, for example poly bag with warning, bubble sleeve, or carton. Use a short pack matrix so staff never guesses. For help, see FBA prep services and pick and pack services.
Accurate ASNs
Carton contents match what the system expects. Book dock times and target a 1 to 3 day dock to stock on your side so replenishments move fast. Learn more under warehousing and storage solutions.
Right size packaging
Use a simple mailer and box matrix to control DIM weight and reduce damages. Tie label creation to the final scan, then print.
Clean data where everyone can see it
Dimensions, weights, hazard flags, and pack rules live in one product master. Keep it visible through real-time information.

Move slow product without burning margin

FBA limits sting when units sit. Make them move or keep them out of FBA.

Send only near term demand
Replenish winners for the next 30 to 45 days. Hold the rest at your 3PL hub and feed as sales prove out.
Age out slow movers
Pull back aging ASINs before fees climb. Clear with light promos from your own site or other channels handled by your 3PL.
Smart kitting
Turn singles into kits or variety packs outside FBA to improve sell through, then send proven kits in. See kitting assembly services.
FEFO for consumables
Capture lot and expiry at receiving and pick FEFO so dated product moves first. Review health and wellness fulfillment services.

Ship fast and cheap even off Amazon

If you route more orders MFN through a 3PL, keep speed and cost tight.

Central U.S. hub
A Cincinnati location reaches most buyers in 1 to 3 days by ground.
Same day handling
Clear one cut off daily. Batch single line orders, cluster pick multi line, and add a second scan at pack for look alike SKUs.
Rate shop every label
Blend nationals with regionals for dense lanes. Protect margin with discounted shipping rates.

FAQ

Should I move everything to FBA
No. Keep FBA for fast movers. Route the tail through MFN or SFP with a strong 3PL so storage fees and limits do not cap growth.

How much inventory should I send to FBA
Aim for 30 to 45 days of real demand, then replenish based on sell through. Keep the reserve at your 3PL.

How do I reduce refusals
Lock FNSKU maps, label placement, and prep rules. Send accurate ASNs and book dock times. Run a small pilot before peak.

Can I still hit Prime level speed off Amazon
Yes. A central Midwest hub with clean pick and pack and rate shopping gets most orders there in 1 to 3 days by ground.

What accuracy should we target
99.7 percent or better. Separate look alikes and add a second scan at pack.
