A customer orders five cosmetic jars from your Shopify store. Meanwhile, another customer is considering the same product, and your warehouse team is preparing existing orders.
How do you know how many jars are still available to sell?
Without accurate inventory records, businesses risk accepting orders they cannot fulfill. They may also reorder products unnecessarily or overlook stock that needs replenishment.
Shopify inventory tracking helps merchants monitor product quantities, manage stock across locations, and keep inventory records connected to store activity.
However, enabling the feature is only the beginning. Reliable inventory management also requires accurate product data and consistent stock procedures.
This guide explains how to set up inventory tracking in Shopify, understand inventory quantities, and apply practical management practices.
What Is Shopify Inventory Tracking?
Shopify inventory tracking is a built-in feature that records inventory quantities for products and their variants.
When tracking is enabled, Shopify can update available inventory as customers place orders through supported store workflows.
For example, suppose your store has 100 glass bottles available.
A customer places an order for 10 bottles. Those units are no longer available for new orders, even though they may still be physically present in your warehouse until fulfillment.
As a result, Shopify helps distinguish stock that exists from stock that can still be sold.
However, inventory accuracy also depends on recording deliveries, returns, damage, and other stock movements correctly.
How to Set Up Shopify Inventory Tracking
Before enabling tracking, confirm that your product records and warehouse quantities are accurate.
Step 1: Open Your Shopify Products
Sign in to your Shopify admin.
Next, open Products and select the product you want to manage.
If the product has multiple variants, select the specific variant.
For example, a 250 ml glass bottle with a black cap may have different inventory from the same bottle with a white cap.
Therefore, each stocked variation should have its own identifiable record.
Step 2: Enable Inventory Tracking
Find the Inventory section on the product or variant page.
Enable the option to track inventory quantities. Depending on the interface, this may appear as Track quantity or an inventory tracking setting.
Next, review the product’s out-of-stock behavior.
For ordinary stocked products, avoid enabling continued sales after inventory reaches zero unless your business can reliably fulfill those orders.
Step 3: Enter Your Starting Inventory
Enter the appropriate inventory quantity for the product.
For example:
| Product Variant | Starting Available Quantity |
|---|---|
| Glass Bottle 250 ml — Black Cap | 150 |
| Glass Bottle 250 ml — White Cap | 100 |
| Cosmetic Jar 100 ml | 250 |
Before saving, verify these figures against your warehouse records.
Incorrect starting quantities can affect every subsequent inventory decision.
Step 4: Save and Verify
Save your changes.
Then, open Products → Inventory to review the quantities.
Check that the correct product variants and locations appear.
If you manage several locations, confirm that inventory is assigned to the intended location.
Understanding Shopify Inventory Quantities
Shopify uses different inventory states to explain where stock stands in the selling and fulfillment process.
| Inventory State | Meaning |
|---|---|
| On hand | Total inventory physically held at a location |
| Available | Inventory available for sale |
| Committed | Inventory allocated to orders or other commitments |
| Unavailable | Inventory held back from sale |
| Incoming | Inventory expected from incoming shipments or transfers |
These quantities are related, but they are not interchangeable.
For example, a warehouse may have 100 units on hand.
Of those units, 20 are committed to orders and 5 are unavailable because they require inspection.
Therefore:
Available = On Hand − Committed − Unavailable
100 − 20 − 5 = 75 units available
Incoming stock is not included in this calculation until it is received into inventory.
Understanding these differences helps prevent incorrect stock adjustments.
How to Update Inventory Quantities in Shopify
Inventory changes for several reasons.
Businesses receive supplier deliveries, fulfill orders, discover damaged products, and correct physical counting errors.
To update inventory, open Products → Inventory.
Find the relevant product or variant, then select its quantity.
Depending on the adjustment, you can set an exact quantity or change the existing balance.
For example, suppose your inventory record shows 80 units, but a physical count confirms only 77.
You may need to correct the quantity and investigate the three-unit difference.
However, avoid making unexplained adjustments.
Shopify records inventory adjustment activity, which can help businesses investigate changes later.
Managing Inventory Across Multiple Locations
Some businesses operate more than one warehouse or retail store.
For example, an ecommerce company may store packaging products in two warehouses.
Shopify supports inventory management by location, allowing merchants to track where products are stocked.
Consider this example:
| Location | Available Stock |
|---|---|
| Warehouse A | 120 |
| Warehouse B | 80 |
| Total | 200 |
Although the total available stock is 200 units, fulfillment depends on location settings and order routing.
Therefore, a product being available somewhere in the business doesn’t automatically mean every location can fulfill an order.
Review your location configuration and fulfillment settings before relying on combined stock totals.
When transferring products between locations, use the appropriate inventory transfer workflow rather than treating the movement as an unrelated stock adjustment.
How to Prevent Overselling on Shopify
Overselling occurs when a business accepts orders for more units than it can supply.
Several practices can reduce this risk.
First, enable inventory tracking for products with limited quantities.
Next, review the Continue selling when out of stock setting.
If customers should not order unavailable products, keep that option disabled.
Additionally, update inventory promptly when products are damaged, lost, or removed from sale.
For businesses using multiple sales channels, verify that inventory synchronization is working correctly.
Shopify tracking alone does not guarantee synchronization with every external marketplace or inventory system.
Shopify Inventory Tracking Best Practices
Use Consistent SKU Codes
A Stock Keeping Unit (SKU) identifies a specific product or variation.
For example:
- BOT-250-BLK: 250 ml bottle with black cap
- BOT-250-WHT: 250 ml bottle with white cap
Consistent SKUs make inventory records easier to review.
They also reduce confusion when employees process orders or update stock.
Perform Regular Physical Stock Counts
Inventory records may differ from actual warehouse quantities.
Therefore, schedule physical counts based on product value, sales activity, and operational risk.
Fast-selling products may require more frequent checks.
Meanwhile, slower-moving products can follow a different counting schedule.
Investigate discrepancies before making corrections whenever possible.
Review Low-Stock Products
Monitor products approaching their replenishment thresholds.
For example, a business selling 10 units daily may need to reorder before available stock reaches zero.
However, reorder decisions should also consider supplier lead times and incoming deliveries.
Separate Damaged Stock
Damaged products should not remain available for ordinary customer orders.
Use appropriate unavailable inventory states when products require inspection or cannot be sold.
This improves the reliability of available inventory quantities.
Monitor Inventory Changes
Review unusual inventory adjustments and investigate unexpected reductions.
For example, repeated corrections to the same SKU may indicate picking errors, inconsistent receiving procedures, or inaccurate product identification.
Addressing the cause is more useful than repeatedly correcting the quantity.
Can You Manage Shopify Inventory in Bulk?
Yes. Shopify supports bulk inventory management.
For example, merchants can use bulk editing
