Never Out of Stock: My Simple Inventory System
Most inventory tools overcomplicate things. I built a simple google sheet that tells me exactly how long my stock will last—no fluff, just what matters.

I hate stockouts.
If you sell on Amazon or Shopify, you know what I mean. No stock = no sales. No sales = no ranking. No ranking = disaster.
I run two brands primarily on Amazon: Eggboards and Third Wheel. I manage five different products. Staying in stock is EVERYTHING... ask me how I know 😭
So, I built my own system to plan new productions and replenish inventory to Amazon FBA—without stress.
The software problem 😤
I tried all the tools.
They looked great on paper: AI-powered forecasting, seamless integrations, automated reordering.
In reality? Complicated, expensive, and unreliable.
Every tool I used promised it would “predict” when I’d run out. Every tool failed.
I still had to double-check everything myself. And when I didn’t? Stockouts happened.
So I ditched them.
The simple fix: A spreadsheet 📊
Nothing fancy. Just a small but mighty spreadsheet. 💪
It tells me exactly how long my inventory will last. Updates in minutes. Works with 1, 5, or thousands of products.
For large catalogs, you may want to change it into a more concise layout, but the core idea stays the same.
The best part? —you can tweak it to fit your business perfectly! ⚡📊
For example: last year, I switched my warehouse from Ship Hero to Flexport.
Took me 10 minutes to update my sheet. No downtime, no extra costs. Total control.
Updating it takes under 4 minutes ⏳
And I don’t even do it myself.
I outsourced it to my Virtual Assistant.
In the video below, I update the spreadsheet in 3 minutes and 25 seconds.
Once updated, I instantly see insights and next steps to avoid stockouts.
No waiting for software to process. No surprises. Just data I can trust.
How you can apply this 🚀
You can download the spreadsheet for free.
Use it to manage your Amazon inventory with zero stress.
Whether you have 1 product or 10,000, you’ll always know exactly how long your stock will last.
No fancy software. No unnecessary costs. Just a simple, reliable system that works.
