Shopify Purchase Orders: Why You Need Them and How to Set Them Up

Shopify doesn't have purchase orders. That's a problem.


A purchase order is a document you send to a supplier saying "I want to buy X units of Y at Z price, delivered by this date." It's the foundation of inventory management.


Shopify has no PO system. When you need to restock, you email your supplier, maybe attach a spreadsheet, and hope you both remember the details. There's no way to track what you ordered, when it's arriving, what it cost, or whether you received everything.


For a store doing $10K/month in sales, this might be manageable. At $50K+, it's chaos.

What purchase orders actually do


1. Track what you ordered


A PO records exactly what you ordered from which supplier: items, quantities, prices, expected delivery date. No more "did I order the red ones or the blue ones?"


2. Know what's coming


Open POs show you what inventory is in transit. This helps you make better decisions: "I have 5 units left, but 50 are arriving Thursday. I don't need to rush-order."


3. Verify deliveries


When a shipment arrives, you check it against the PO. Did you receive everything? Were the quantities right? Any damaged items? This catches supplier errors before they become your problem.


4. Track costs


POs record what you paid. Over time, this builds a cost history: "Last order was $12/unit, this time they want $14. Time to negotiate or find a new supplier."


5. Create an audit trail


Every purchase is documented. Your accountant loves this. Tax season is easier. Inventory valuations are accurate.
