Amazon Inventory Management

Amazon Inventory Management That Prevents Stockouts and Storage Fees

Stockouts don’t just cost you the sales you missed — they cost you the organic rank you spent months and ad dollars earning, and getting it back is more expensive than never losing it. Overstock costs you the other way, in long-term storage fees, capital tied up in slow SKUs, and a restock limit that shrinks right before Q4.

Comprehensive Execution

What’s included in our amazon inventory management services

Sellarank manages the line between the two with forecasting built on your actual velocity, seasonality and lead times.

01

SKU-level forecasts built from sales velocity, seasonality, promotional calendar and planned ad spend — not a flat 30-day average.

Restock and reorder planning

02

Reorder points and quantities calculated against supplier lead times, freight transit and Amazon receiving times, so POs go out before the shortfall, not after.

IPI and capacity management

03

Ongoing IPI monitoring and the levers that move it — sell-through, stranded inventory, excess and in-stock rate — to keep your storage capacity where you need it.

Stranded and aged inventory recovery

04

Identifying stranded, unfulfillable and aged stock, then relisting, removing or liquidating it before the surcharges compound.

Shipment and FBA plan management

05

Shipment creation, box and pallet planning, labelling requirements and tracking through to receipt, plus follow-up on lost or short-received units.

Multi-channel and 3PL coordination

06

Allocation across FBA, FBM and 3PL, so one channel’s demand spike doesn’t strand another.

Target Fit

Who our amazon inventory management services is for

Built specifically for serious marketplace operators and growing consumer brands that need predictable execution without the agency overhead.

Seasonal brands — Q4 and category-peak planning where a stockout is a year’s damage.

Long lead-time importers — 60–120 day supply chains that need forecasting, not reaction.

Fast-growing SKUs — velocity that outruns last month’s plan.

Sellers hitting restock limits — IPI recovery before capacity bites.

Multi-SKU catalogues — allocation logic across dozens or hundreds of ASINs.

Brands with capital tied up in slow stock — liquidation and rationalisation plans.

The Sellarank Standard

Why brands choose Sellarank for amazon inventory management services

We do not sell black-box promises or inflated projections. We sell disciplined decision quality, unit-level profitability, and operator accountability.

01

Forecasts that include your ad plan

Most forecasting ignores marketing. If you’re about to scale PPC on a SKU, the demand curve changes — we model that.

02

We treat rank as inventory value

The real cost of a stockout is the organic position you lose. That’s factored into every reorder decision.

03

Fee-aware planning

Size tiers, storage utilisation surcharges, aged inventory and removal costs are all part of the maths.

04

Month to month

No lock-in.

Amazon Inventory Management Services FAQs

Common questions regarding amazon inventory management services, pricing, SLAs, and operating deliverables.

How do I stop running out of stock on Amazon?

By reordering against a forecast that accounts for sales velocity, seasonality, promotions, planned ad spend and total lead time — including supplier production, freight and Amazon’s receiving time, which sellers routinely underestimate.

What is an IPI score and why does it matter?

Your Inventory Performance Index is Amazon’s rating of how efficiently you use FBA storage, driven by sell-through, stranded inventory, excess inventory and in-stock rate. A low IPI can trigger restock limits and storage overage fees — usually at the worst possible time of year.

How long does it take to recover organic rank after a stockout?

It varies by category and length of the outage, but recovery commonly takes several weeks and often requires paid spend to rebuild velocity. It is materially more expensive than preventing the stockout.

Can you reduce my FBA storage fees?

Yes — through aged inventory removal, better sell-through planning, right-sizing shipment quantities and, where relevant, packaging changes that move a product into a lower size tier.

Do you manage the physical shipments too?

We manage shipment creation, planning, labelling requirements and tracking, and coordinate directly with your existing 3PL or freight forwarder. We do not run our own prep centre or warehouse — we work alongside the logistics partner you already use, and can recommend one if you do not have a partner yet.

How much does inventory management cost?

It’s included in full account management, or available standalone from $1,295/month.
