Shopify Inventory Management: The Complete Guide for 2026

Shopify's inventory tools are basic. Here's how to fix that.#

If you're running a Shopify store with more than a handful of products, you've probably hit the wall. Shopify tracks quantities. That's about it. No purchase orders, no demand forecasting, no real alerts, no supplier management.

This guide covers everything you need to know about managing inventory as a Shopify seller in 2026 — what Shopify does, what it doesn't, and how to fill the gaps.

What Shopify gives you (and where it stops)#

What works

• Quantity tracking per location — Shopify shows how many units you have at each location
• Auto-decrement on sale — when someone buys, stock goes down automatically
• Transfers between locations — move inventory from Warehouse A to Store B
• Inventory history — basic log of quantity changes

What's missing

• Purchase orders — Shopify has no way to track what you've ordered from suppliers, when it ships, or what it costs. You're doing this via email, spreadsheets, or not at all.
• Reorder points — no automatic "hey, you're running low on this" alerts. There's a low stock report you have to manually check.
• Demand forecasting — Shopify shows what sold last month. It doesn't predict what will sell next month. No seasonal adjustments, no velocity tracking.
• Cost tracking — the "cost per item" field exists but Shopify doesn't calculate margins, COGS, or profitability per product.
• Supplier management — just a "vendor" text field on each product. No contact info, lead times, price lists.
• Barcode scanning for warehouse work — Shopify POS can scan barcodes for checkout, but there's no scanning for receiving shipments, doing physical counts, or picking orders.

If you're under 50 SKUs, Shopify's built-in tools work fine. At 100+, the gaps become painful. At 500+, they become expensive.

The Stocky situation#

Shopify used to offer Stocky — a free inventory management app with purchase orders, demand forecasting, and stock reports. It was the answer to most of these gaps.

Stocky was removed from the Shopify App Store on February 2, 2026, and shuts down completely on August 31, 2026.

If you're still using Stocky, you need a replacement before August. If you never used Stocky, you need to know that the features it provided — POs, forecasting, receiving workflows — aren't available anywhere in native Shopify anymore.

Multi-location inventory on Shopify#

Shopify supports multiple locations (up to 10 on Basic, more on higher plans). Each product variant has a separate quantity per location. This is powerful but adds complexity:

• Which location fulfills which order? Shopify can auto-assign based on proximity or priority rules, but you need to keep stock accurate at every location.
• Transfers — moving stock between locations is supported but basic. No transfer tracking, no in-transit status, no receiving confirmation.
• POS locations — if you have retail stores using Shopify POS, they share the same inventory pool as your online store. A sale in-store reduces online availability instantly.

The multi-location problem

The more locations you have, the harder it gets to know:

• Where should I restock first?
• Which location is overstocked?
• What's in transit between locations?
• What's my total inventory across all locations?

Shopify shows you the numbers but doesn't help you make decisions. That's where third-party tools come in.

How to set up reorder points#

Shopify doesn't have reorder points natively. But you can set them up manually or with an app:

Manual approach

1. For each product, note the daily sales rate (check Analytics > Reports > Sales by product)
2. Multiply by supplier lead time (days to receive new stock)
3. Add safety stock (buffer for unexpected demand)
4. Formula: Reorder Point = (Daily Sales × Lead Time) + Safety Stock
5. Check your inventory weekly against these numbers

This works at 20 products. At 200, it's unsustainable.

With inventory software

Tools like InventoryQuick calculate reorder points automatically using your actual sales data. When stock hits the threshold, you get an email or SMS alert. Some tools also generate purchase orders with one click when you hit a reorder point.

Purchase orders for Shopify sellers#

Shopify has zero PO functionality. When you need to reorder from a supplier, your options are:

1. Email the supplier — no tracking, no receiving confirmation, easy to forget
2. Spreadsheet — better than email, but manual and error-prone
3. Third-party app — tools like InventoryQuick, Prediko, or inFlow add full PO workflows

What a good PO workflow looks like

1. You see an item is running low (alert or report)
2. Create a PO with supplier, items, quantities, and expected cost
3. Send PO to supplier (email or PDF)
4. When shipment arrives, mark items as received
5. Stock automatically updates in Shopify
6. Cost and receiving history tracked for audit

This is table stakes for any business ordering regularly from suppliers. The fact that Shopify doesn't have it natively is their biggest inventory gap.

Demand forecasting#

Forecasting means predicting how much of each product you'll need in the future based on historical sales patterns. This helps you:

• Order the right amount — not too much (dead stock), not too little (stockouts)
• Plan for seasonal spikes — holiday season, summer slowdown, back-to-school
• Optimize cash flow — don't tie up money in inventory you won't sell for months

Shopify provides historical sales data but no forecasting tools. After Stocky's removal, there's no native forecasting at all.

ML-powered forecasting

Some inventory tools use machine learning to analyze your sales patterns and predict future demand. InventoryQuick uses ML models trained on the sales history you record in InventoryQuick to forecast stockouts before they happen and recommend optimal reorder quantities.

Barcode scanning for Shopify inventory#

Shopify POS supports barcode scanning for checkout (selling to customers). But for warehouse operations — receiving shipments, doing physical counts, picking orders — there's no native scanning.

What you need

• Receiving: Scan each item as it arrives to verify the shipment matches your PO
• Counting: Walk the warehouse with a scanner instead of manually counting and typing
• Picking: Scan items as you pack orders to prevent shipping errors
• Lookup: Scan a barcode to instantly see stock level, location, and price

InventoryQuick includes barcode scanning from any phone camera — no special hardware needed. Scan to look up items, adjust stock, or check items in and out.

Choosing an inventory management app for Shopify#

When evaluating tools, look for:

1. Real-time Shopify sync — stock changes should flow both directions without delay
2. Variant support — each size/color combination needs independent tracking
3. Purchase orders — the #1 missing feature from Shopify
4. Alerts — email or SMS when stock hits your reorder point
5. Mobile app — for warehouse scanning and on-the-go stock checks
6. Affordable pricing — you shouldn't pay $200+/mo for features Shopify should include

Price comparison

Getting started#

1. Audit your current situation — How many SKUs? How many locations? How often do you stockout? How do you reorder?
2. Identify your biggest pain point — Is it stockouts? Manual POs? No forecasting? Multi-location chaos?
3. Try a tool — Most offer free trials. InventoryQuick has a 7-day free trial; Shopify sync is built (new store connections are paused), so you can start by importing your catalogue via CSV.
4. Start with one improvement — Don't try to fix everything at once. Set up reorder alerts first, then POs, then forecasting.
