What our inventory management service covers
Restock and inbound planning
Restock quantities and timing set from forecast, lead times and FBA capacity limits, with inbound shipments created and tracked to check-in.
AWD and 3PL coordination
Upstream storage through Amazon Warehousing and Distribution or your 3PL planned so FBA stays topped up without excess storage costs.
Fee control
Low-inventory-level fees, aged-inventory surcharges, storage and inbound placement fees monitored and reduced through better stock levels and shipment choices.
Stranded inventory and reimbursements
Stranded, suppressed and unfulfillable units fixed or removed, and claims filed for lost or damaged FBA units.
Planned with ads and deals
Ad budgets, deals and launches planned against stock, so we do not spend to drive sales on products about to run out.
Common inventory problems, and what we change
| What it costs | What we do | |
|---|---|---|
| Stock-outs | Lost sales, lost ranking and wasted ad spend | Forecast demand, set reorder points and buffer stock |
| Too much stock | Storage fees, aged-inventory surcharges and tied-up cash | Slow inbound, run targeted deals, plan removals |
| Too little stock at FBA | Low-inventory-level fees and slower delivery | Keep enough weeks of cover at FBA, top up from AWD or 3PL |
| Capacity limits | Shipments cannot be sent when needed | Plan inbound by month and prioritise best sellers |
| Stranded or lost units | Inventory that cannot sell or is never reimbursed | Fix listings, remove units and file claims |

Why inventory is a growth problem, not just an operations one
On Amazon, running out of stock does more than lose a few days of sales. Organic ranking slips, ads stop serving and competitors take the traffic, and it can take weeks to recover. Holding too much stock costs money too, through storage fees, aged-inventory surcharges and cash tied up in slow products. Good inventory management keeps products in stock with the least cash and fees, which is why we run it alongside ads and listings.
FBA fees that reward good planning
Amazon now charges for both extremes. Low stock at FBA relative to demand can trigger low-inventory-level fees, while stock that sits too long attracts aged-inventory surcharges and higher storage costs, and inbound placement fees depend on how shipments are sent. We track these fees by product, set target weeks of cover and choose shipment options that balance fees with speed.
Capacity limits, AWD and 3PLs
FBA capacity limits cap how much you can send in, so inbound has to be planned by month and prioritised for best sellers. Many brands keep upstream stock in Amazon Warehousing and Distribution or a 3PL and top up FBA from there. We plan transfers, watch capacity and keep the fastest-moving products covered first.
Planned with ads, deals and launches
Inventory plans fail when they ignore marketing. A big Prime Day push, a new product launch or a jump in PPC budget all change demand. Because the same team runs ads and inventory, budgets are raised only when stock can support them and paused before a product runs out. Consumable brands also need stock for Subscribe and Save deliveries. We manage $3M+ in monthly ad spend across our clients. Results depend on product, margin and category, and we share a plan after reviewing your account.
Stranded inventory and reimbursements
Units can get stranded when a listing breaks, become unfulfillable after damage or go missing in Amazon’s network. We fix the listing issues, plan removals or liquidations where they make sense and file reimbursement claims for lost and damaged units. See our Amazon reimbursement services.

Frequently asked questions
Is there an Amazon agency that handles inventory planning?
Yes. CommerceKind manages FBA inventory for brands: demand forecasts, restock and inbound planning within capacity limits, AWD or 3PL coordination, fee control, stranded inventory fixes and reimbursements, planned together with your ads, deals and launches.
How do I stop running out of stock on Amazon FBA?
Forecast demand by product including seasonality, ads and deals, set reorder points from your supplier lead times, keep buffer stock upstream in AWD or a 3PL and plan inbound shipments around FBA capacity limits.
What is the Amazon low-inventory-level fee?
It is a fee Amazon can charge on some FBA products when stock at Amazon is low compared with recent sales. Keeping enough weeks of cover at FBA usually avoids it. We track it by product.
What is Amazon Warehousing and Distribution (AWD)?
AWD is Amazon’s upstream storage service that holds bulk inventory and can replenish FBA automatically. It can lower storage costs and help with capacity limits for some brands. We compare it with your 3PL.
How do FBA capacity limits work?
Amazon sets limits on how much inventory you can send to FBA over a period, based on factors such as sales and inventory performance. We plan inbound by month so best sellers stay in stock within those limits.
Can you reduce our FBA storage and aged-inventory fees?
Usually, yes. We right-size inbound quantities, move slow stock with targeted deals, plan removals where needed and keep weeks of cover in a healthy range.
Do you also run our ads and listings?
Yes. We run Amazon PPC, listings and account management alongside inventory, so ad budgets match stock and launches have enough inventory.
Can my agency white-label inventory management?
Yes. Agencies can offer inventory management under their own brand through our white-label Amazon inventory management service, with an NDA and non-solicit first.
