The Shopify inventory stack I wish I had when I started — and what I'd never go back to

Spent the first year of my Shopify store managing reorders in a Google Sheet.

Column A: product. Column B: quantity on hand. Column C: "probably need to order soon?" Column D: a date I'd copy-paste from an email thread with my supplier.

It worked until it didn't. A stockout on my bestseller during Q4 cost me more than I made that month.

Here's what I learned the hard way — and what I'd tell any merchant who's still running this system:

The real problem with spreadsheet inventory isn't accuracy. It's latency.

A spreadsheet tells you what was true when you last updated it. Shopify is updating your inventory in real time — every sale, every return. Your sheet isn't.

By the time you catch a low-stock situation, you've already lost sales you'll never see. The customer didn't wait. They bought from someone else.

The second problem: the gap between "I need to reorder" and "the PO is sent."

Even if you catch it in time, there's still a full manual process between knowing you need to reorder and actually having a purchase order in your supplier's inbox:

1. Open a new spreadsheet or Word doc

2. List the SKUs, quantities, prices

3. Export to PDF

4. Email it to the supplier

5. Pray they respond with a confirmation

6. When inventory arrives, manually update Shopify

That's 6 steps that all live outside Shopify. Every single time.

What the workflow looks like when it's actually connected:

Sales velocity flags a product as low-stock → you review and approve the reorder quantity → a PDF purchase order is generated automatically → supplier gets it by email in one click → when stock arrives, you mark it received → Shopify inventory updates.

That's the loop EZStock closes. Every step lives inside your Shopify admin. No spreadsheet. No copy-paste. No separate supplier email chain.

If you're a product-based Shopify merchant and you're still doing this manually — I genuinely want to hear what your current setup looks like.
