Do you need admin access to our Seller Central account?

We work with a dedicated user under your account with only the permissions the work requires: inventory, shipments, and cases. You keep ownership and can revoke access at any time.

Do you place the purchase orders with our suppliers?

We build and recommend the buy plan, and we coordinate with suppliers on lead times and production. Whether we place the PO ourselves or you approve and place it is your call, and both are common.

What if we sell on Amazon and elsewhere?

That is the normal case. Allocation across FBA, Shopify, Walmart WFS, and TikTok Shop is planned together, because a unit committed to one channel is a unit the others cannot sell.

How fast can you take over?

Onboarding runs about two weeks. The first week is access, data, and reconciling what your current inventory position actually is. The second is setting reorder points and taking the shipment cadence live.

Is our account and business data secure with you?

Each operator has their own named user on your account with only the permissions the work needs, never a shared login and never your password. Access is logged, reviewed when someone changes accounts, and revoked the day they come off the engagement or leave. We do not retain personally identifiable information, and we do not share your data with any other client. The full set of controls, including our incident response commitments, is published on our security page.

A fixed monthly fee, quoted against your channel count, active SKU count, inbound volume, supplier count, and the coverage you need. There is no commission on purchase orders, no percentage of recovered reimbursements, and no software licence on top. The pricing page sets out exactly how the number is built and what is inside it.

The problem

What this actually feels like.

FBA punishes the same three mistakes over and over. You send too little of the SKU that is selling and burn a week of velocity getting it back in stock. You send too much of the one that is not, and pay long-term storage on it through Q4. And somewhere in the middle, a shipment gets received short, a unit gets destroyed in a fulfillment center, and nobody files the claim because nobody owns filing claims.

The dashboards tell you this after the fact. Restock limits move without warning. IPI drops and suddenly the storage you were counting on is gone. Meanwhile the person nominally running FBA is also running your ads, your listings, and your customer service, so FBA gets whatever is left of a Thursday.

None of this is hard. It is just relentless, and it does not fit around another job.

What we own

Off your plate, not just advised on.

Replenishment and shipment plans

We set reorder points per ASIN against real sell-through, build the shipment plans, split them across the fulfillment centers Amazon assigns, and book the freight. You approve the buy; we handle everything after it.

Restock limits and IPI

We track your restock limits and Inventory Performance Index weekly, flag which SKUs are dragging the score, and clear excess before it turns into long-term storage fees rather than after.

Removals and aged stock

Aged inventory gets a decision, not a shrug. We run removal orders, liquidation, or a return-to-3PL depending on what the unit economics say, and we tell you which one we picked and why.

Reimbursements and discrepancies

Every inbound shipment gets reconciled against what Amazon actually received. Lost, damaged, and short-received units get claimed inside the filing window, with the case documentation attached.

Multi-channel coordination

If you also sell on Shopify, Walmart, or TikTok Shop, allocation across those channels is part of the same plan. FBA does not get to hoard the units that another channel needs.

Inside your account

Every area we touch, and the access it needs.

Handing over standing access to your selling account is a real decision. This is the whole list, area by area, with the permission level each one needs and why it is not more.

Manage Inventory, Add a Product, and Upload Inventory

Edit access

Replenishment settings and quantities have to be written, not just read. Editing is confined to inventory attributes; we do not write listing copy, images, or A+ content.

Maintain replenishment and restock attributes per ASIN so the restock recommendation reflects the real reorder point.
Correct quantity, condition, and fulfillment-channel settings when a SKU is mis-set.
Bulk-update inventory attributes through flat files where a change spans hundreds of SKUs.
Switch SKUs between fulfilled-by-Amazon and merchant-fulfilled when the unit economics change.

Manage FBA Inventory and Shipments, and the shipping queue

Edit access

Building a shipment plan is a write action end to end: creating the plan, accepting the fulfillment center split, generating labels, and confirming the carrier.

Build shipment plans against the buy plan, sized to restock limits rather than to what is in the warehouse.
Accept and work with the fulfillment center split Amazon assigns, including splitting a purchase order across destinations.
Generate box and shipment labels, set box content, and pass prep and labelling requirements to the warehouse.
Book the freight, schedule the delivery appointment, and track the shipment through to receipt.
Reconcile received units against shipped units and open the discrepancy where they differ.

Inventory Planning, inventory performance, and restock limits

Edit access

Removal orders and excess-inventory actions are write actions, and they are time-sensitive. Waiting for a client to click through a removal is how aged stock turns into a long-term storage bill.

Track restock limits and the Inventory Performance Index weekly, and identify which ASINs are dragging the score.
Flag aged and excess inventory before the long-term storage date rather than after it.
Create removal, liquidation, and return-to-warehouse orders on the disposal decision agreed with you.
Manage Amazon Warehousing and Distribution positions and transfers into fulfillment centers where you use it.

Manage Your Cases

Edit access

A claim has to be filed, evidenced, and argued, which means opening and replying to cases. This is the single largest source of money recovered in a typical engagement.

File claims for units lost, damaged, or destroyed inside the fulfillment network, inside the filing window.
File inbound discrepancy claims where a shipment was received short, with the shipping evidence attached.
Work fee and dimension disputes where a SKU is being billed at the wrong size tier.
Track every open case to resolution and report which are outstanding and what they are worth.

Shipping settings, shipping policies, and carrier pickup

Edit access

Handling times and ship-from settings drive the delivery promise, and a stale setting quietly costs conversion. These are configuration changes, so they need write access.

Maintain handling times and ship-from locations so the delivery promise matches what the warehouse can actually do.
Configure shipping templates and regional rates for merchant-fulfilled SKUs.
Set up and adjust carrier pickup for merchant-fulfilled volume.
Keep estimated ship dates honest when a supplier or warehouse slips.

Inventory, fulfillment, and business reports

View access

Reporting is read-only by nature. Everything the forecast needs, sell-through by SKU, received quantities, returns, and fee detail, is available in reports without touching customer records.

Pull sell-through and velocity per ASIN per marketplace as the input to the demand forecast.
Reconcile inbound receipts, returns, and adjustments against our own records.
Track storage, removal, and long-term storage fees per SKU so disposal decisions have real numbers behind them.
Report weeks of cover, stockout risk, and excess position back to you every week.

What we do not ask for

We do not ask for access to customer-identifying order data. SKU-level demand comes from inventory and business reports, which carry the product and quantity fields we need without the buyer attached.
We do not write or edit listing copy, images, A+ content, or brand stories. That is a content service and we are not one.
We do not set or change prices, and we do not run repricing. Where a pricing decision affects the buy plan, we tell you and you decide.
We do not create or manage deals, coupons, or promotions. We plan the stock behind a promotion you have decided to run.
We do not manage advertising campaigns or budgets.
We do not need banking, tax, or user-permission administration on your account, and we will decline it if offered.

How access is granted, logged, and revoked is set out in full on our security page.

What you get out of it

The outcomes this is bought for.

Fewer stockouts on the SKUs that actually sell

Reorder points are set per ASIN against real sell-through and a lead time with its real variability, then reviewed weekly. The failure mode we are designed against is being out of stock on your best seller while sitting on eight weeks of cover on a slow one.

Less capital sitting in inventory that is not moving

Excess is identified against cover, not against a feeling, and aged stock gets a decision before the long-term storage date rather than after it. That is cash back rather than a fee paid.

Money recovered that would otherwise be written off

Every inbound shipment is reconciled against what was actually received, and lost, damaged, and short-received units are claimed inside the filing window with the evidence attached. Most brands lose this money simply because nobody owns filing the claim.

Storage and fee exposure that goes down rather than up

Restock limits and the Inventory Performance Index are tracked weekly, so the score is managed before it costs you storage rather than explained afterwards.

Problems worked overnight instead of queued

Three shifts cover your suppliers’ working day, the overlap, and yours. A shipment stuck at receiving does not wait until someone in your timezone wakes up.

One inventory position across every channel you sell on

If you also sell on Shopify, Walmart, or TikTok Shop, allocation is decided once, centrally. FBA does not get to hoard units another channel has already sold.

A plan you can see, and an operator who owns it

One named person is accountable for the account. You get a weekly written review of what moved, what we did, and what is at risk, not a dashboard you have to interpret yourself.

Month one

What you see in the first thirty days.

A full inventory position by ASIN: what is healthy, what is about to stock out, what is aged and costing you storage.
Reorder points and safety stock set per ASIN instead of per gut feel, with the assumptions written down.
A reimbursement sweep on the trailing claim window, with every filed case listed and tracked.
A weekly shipment cadence you can see, so you stop finding out about a stockout from a customer.

How access works

Yours to grant, and yours to take back.

You grant access. We never ask for your password.

Each of our operators works under their own named user on your account, created by you, with only the permissions the agreed scope needs. We will not accept a shared login, and we will not accept credentials sent over email or chat.

Permissions are set to the work, not to convenience.

We ask for edit access only where the task is a write action, and view access everywhere else. If a permission is offered that the scope does not need, we decline it. The table above is the whole list.

Every action is attributable.

Because access is per person rather than shared, the account history shows which operator did what. We keep our own access logs alongside it.

You can revoke at any time, and we hand back cleanly.

Access is yours to withdraw without notice to us. When an engagement ends we also revoke from our side, close the operator accounts, hand back the working documents, and delete the operational records we hold.

Expertise

Why we are the ones holding the keys.

Running Amazon supply chain operations for e-commerce brands since 2020, as Ecom Store LLC, a registered Wyoming limited liability company.
Our operators have run FBA accounts directly rather than advised on them. Every account is owned end to end by one of them.
Operators complete Amazon Seller University coursework on FBA inventory management, inbound shipment creation, and account health as part of onboarding.
FBA policy changes are tracked in internal documentation that is reviewed and reissued to the operations team, because the rules that generate chargebacks change more often than the ones that do not.
We operate under Amazon's Data Protection Policy for all Selling Partner data we are given access to, with the controls published in full on our security page.

The company behind this service, our credentials, and what the brands we run operations for say about the work are set out on our testimonials page.

Proof

We publish the engagements where the numbers are ours to share, including a 3PL invoice audit that recovered $6,047 and a fulfillment error recovery across a Canadian warehouse. The same reconciliation discipline is what catches Amazon receiving discrepancies.
