MobyShelf

The winners run out. The losers never do.

That sentence is the whole problem with inventory. Your best sellers stock out on a Friday and you lose the rank you spent months building; your worst buy sits in a warehouse for eleven months paying rent. MobyShelf watches both ends — and tells you a specific number of units and a specific date, while there is still time to do something about it.

Why it exists

Stock is the only asset that costs you money while you own it

Cash in a bank account sits still. Cash in the form of inventory is quietly billed for storage, and loses value the longer it stays.

Today

Counting from memory

  • ×A spreadsheet that was accurate on Tuesday and has since become a work of historical fiction.
  • ×Units in your garage, at the prep centre and at Amazon — and only one of those three reports back.
  • ×A best seller goes out of stock on Friday evening; you find out on Monday from a dip in sales.
  • ×Dead stock reaches the long-term storage surcharge and you pay rent on a decision made ten months ago.
  • ×Stranded and unfulfillable units sit invisibly with inventory attached and no live offer.
With MobyShelf

Counting from the ledger

  • ✓One ledger per SKU across every location, updated as units move rather than as somebody remembers.
  • ✓Available, inbound, reserved, at prep and unfulfillable counted separately, because they are not the same thing.
  • ✓Restock forecasts from your actual sell-through and your actual supplier lead time.
  • ✓Ageing buckets show what is heading toward a surcharge months out, while a markdown still recovers something.
  • ✓Stranded, suppressed and unfulfillable units arrive as a worklist instead of a discovery.
What it does

Everything you own, in one place, honestly counted

Inventory software fails in one of two ways: it tells you a number that is wrong, or it tells you a number too late. Both are addressed here.

01

One ledger, every location

Your shelf, the prep centre, a 3PL, FBA and everything in transit between them. Available, reserved, inbound and unfulfillable are counted as separate states, because a reserved unit is not a unit you can sell.

02

Restock forecasts you can act on

Sell-through per SKU, your supplier lead time and the safety stock you are comfortable with, resolved into days of cover and a reorder date. Not a vague warning — a number of units and a deadline.

03

Ageing before it costs you

Units bucketed by days on hand, with alerts that fire while a markdown, a bundle or a removal still makes financial sense. By the time a surcharge lands, the decision has already been made for you.

04

Shipment plans and box contents

Build FBA shipments from listed units, handle split warehouse assignments, record what actually went into each box and produce the 2D box-content labels.

05

Stranded stock clean-up

Suppressed listings, stranded inventory, unfulfillable units and pending removals gathered into one list with a suggested action against each — relist, remove, or dispose.

06

No oversells, anywhere

One stock pool feeds every channel you sell on. When MobyChannel is switched on, a unit sold on one marketplace cannot be sold again on another.

How it works

From count to reorder, without a spreadsheet

The point of this section is that after the first setup, MobyShelf should be telling you things rather than waiting to be asked.

01

Bring your stock in

Connect FBA, add your own locations and import a count. Units already listed through MobyLister arrive with their cost and source attached.

One-time setup
02

Let velocity build

Sell-through is measured per SKU, per marketplace. You supply lead time and the safety stock level you can live with.

Sell-through data
03

Act on the date

Restock and ageing alerts arrive with a unit count and a deadline attached, in time to do something rather than to explain something.

Alerts with numbers
04

Ship and update

Build the shipment and watch the ledger move the units from your shelf to inbound to available.

The number that drives the decision

“Days of cover” beats “units in stock” every time

A unit count means nothing on its own. The same count set against your supplier’s lead time and how fast the SKU actually sells tells you how long you have to place an order — and that is a decision rather than a statistic. MobyShelf leads with the second number.

  • Cover is calculated from recent velocity per SKU, not from a flat monthly average that hides a seasonal spike.
  • Inbound units count toward cover, so you are not warned twice about a shipment already on its way.
  • Ageing is tracked from the date a unit was received, which is the date the storage clock actually starts.
  • Every alert names the SKU, the quantity and the date — the three things you need to place an order.
“
Every unit you own is either earning rent or paying it.

MobyShelf exists to keep the first group well stocked and the second group short-lived.

Getting it

Buy MobyShelf on its own, or as part of a plan

Most sellers reach for this at the point where they can no longer hold their stock position in their head — usually somewhere around a thousand units.

Bizimle konuşun 214 214 MOBY
Does it track stock outside Amazon?

Yes. Your own shelf, a prep centre, a 3PL and units in transit are all locations you can define, each with its own count. FBA is simply one of the locations rather than the whole picture, which matters as soon as you hold buffer stock outside Amazon.

How does it know my sell-through rate?

From your actual order history per SKU and per marketplace, weighted toward recent weeks so a seasonal change shows up while it is still happening. You can override the forecast for a SKU you know is about to behave unusually.

What lead time should I enter?

The real one, door to door: supplier dispatch, transit, prep and Amazon check-in. Sellers who enter only the supplier’s quoted lead time are the ones who stock out anyway, because the last two steps are where the days actually go.

Will it stop me overselling across channels?

When MobyChannel is switched on, yes — one stock pool serves every channel and a unit sold in one place is decremented everywhere. Without MobyChannel, MobyShelf still gives you a single true count, but the channels themselves are not linked.

Can it build FBA shipments?

Yes, including split shipments across warehouses, box content records and the 2D box-content labels. The ledger moves units from your shelf to inbound to available as the shipment progresses.

What does it do about stranded inventory?

It surfaces it. Stranded units, suppressed listings and unfulfillable stock appear in a worklist with the reason attached and a suggested action — relist, remove or dispose. The value here is that they stop being invisible.

Does the stock item limit on my plan include units or SKUs?

Stock items, meaning distinct items you are tracking, not the number of units of each. A thousand items on Minnow is a genuinely large catalogue for a solo seller; the number of units behind them is unmetered.

Can I import my existing counts?

Yes, from a spreadsheet. It is worth doing a physical count at the same time — the most common surprise in the first week is not a software problem, it is that the old number was already wrong.
