Built by a 12-year Fortune 500 supply chain manager

Your inventory.
Finally simple.

InventorySimpl gives Amazon sellers the same clarity a Fortune 500 supply chain team runs on, without the Fortune 500 headcount. First up: the Smart Inventory Planner.

Every unit sitting in a warehouse past its time is cash you can't spend. Every empty shelf is a sale you'll never get back.

OVERSTOCK

Money tied up in units that already passed their reorder point, quietly shrinking the cash you have to work with.

STOCKOUT

A best-seller runs dry during a peak week, and the sales you would have made simply never happen.

The first InventorySimpl tool

Meet the Smart Inventory Planner.

A simple spreadsheet that flags exactly when your Amazon stock is running low, or piling up and quietly draining your cash. Set it up once. Check it in ten minutes a week.

Min/Max thresholds by SKU

Set the floor and ceiling for every product you sell, based on your own lead times.

Reorder point calculator

The sheet does the math on when to place your next order, so you don't have to.

Days-of-inventory countdown

See at a glance how many days of stock are left at your current sales pace.

Cash-impact view

Understand how much cash is tied up in excess stock versus at risk from a stockout.

3-minute setup video

A short walkthrough shows you exactly where to plug in your numbers, start to finish.

Just Excel

A simple Excel worksheet you already know how to open. No new software to learn.

How it works

Three steps. No complex setup, no new software.

01 / Enter

Plug in what's on hand

Type in your current stock per SKU. No integrations, no logins, no waiting on an API to sync.

02 / See

Read your thresholds at a glance

Color-coded flags show what's above max, below min, or right where it should be, before it becomes a problem.

03 / Act

Reorder with a number, not a guess

Know exactly when to place the next order and how much to order, backed by your own sales pace.

Pricing

One-time purchase. Yours to keep.

Beyond the tool

When you need a person, not a spreadsheet.

Some problems need judgment, not just a threshold. These are the same skills I used running supply chains for a Fortune 500 company, available directly to you.

Questions sellers ask before buying

Do I need any special software?

No. The Smart Inventory Planner is a simple Excel worksheet. If you have Excel, you already have everything you need.

I'm not a spreadsheet person, is this too complicated?

You type numbers into cells. The sheet does the rest. The setup video walks through it in under five minutes.

Does this replace Jungle Scout or Sellerboard?

No, and it's not trying to. This is a focused tool for one job: knowing your min and max stock levels and what they mean for your cash. Keep your other tools for the rest.

Is this a subscription?

No. It's a one-time purchase. You own the sheet and can duplicate it as many times as you need.
