Inventory management for your store

Keep an accurate count of each product and variant so you can identify differences before making another adjustment. Use the appropriate stock location when your store manages more than one location.

Organize products, variants and stock

• Product: the item you sell, such as a T-shirt.
• Variant: a specific combination of its options, such as a blue T-shirt in size M. Check each combination separately.
• SKU: the reference used to identify a product or variant in your operation. Use a consistent system when picking orders or investigating differences.

A count of 12 T-shirts is not enough if you sell several sizes: record each variant separately. For stock held in several places, review multiple stock locations before adjusting a particular warehouse.

Choose an update method

Need	Method	Check before applying
Correct a few quantities after a count	Inventory list	Selected variant and location.
Increase or decrease several variants by the same quantity	Inventory bulk actions	Selected products and operation.
Update many quantities by location	Inventory CSV	A recent export, location columns and UTF-8 encoding.
Coordinate stock with an external system	API or integration	Which system owns stock and how duplicate adjustments are avoided.

The inventory CSV updates stock quantities. To create products or change other catalogue data, use product import.

Keep a regular stock routine

1. Count physical units by variant and location. Use a reference time to distinguish sales made after the count.
2. Compare the count with the panel and check history before correcting a difference. A pending order may already have reduced available stock.
3. Apply each adjustment once. If an ERP or integration manages stock, confirm which system should record the change.
4. Review a sample of variants after updating, especially after a bulk import.
5. Review low-stock thresholds and notifications before the next replenishment.

Example: a pending order and its payment

If a variant has 10 units and an order for 2 units moves to Pending, its stock becomes 8. When that same order moves to Paid, stock stays at 8: do not manually deduct the units a second time. The existing stock-state rules are:

• New to Pending: stock decreases.
• Pending to Paid: no further stock change.
• Pending to Abandoned: stock returns to inventory.
• Pending/Paid to Canceled: stock returns to inventory.

Investigate a difference before adjusting

Check the variant, location, stock history and order states first. Then review manual adjustments, imports and updates from external integrations. Finding the cause first helps avoid another duplicate correction.

Use the inventory screen

Open Products > Inventory to review product or variant, SKU, stock and low-stock threshold. Import, Export and Save appear at the top; Save stays disabled while there are no changes.

The screenshot is from a real test store. This review inspected the interface without changing quantities, importing files or exercising order-state stock transitions.

Update quantities with the inventory CSV

Export a recent file from Inventory, identify the relevant variant and location columns, and update the stock quantities. Save the file as UTF-8 CSV before importing. This stock-specific file does not create new products or change product names or SKUs; use the product-import workflow for catalogue changes.

Keep a copy of the export, apply the update once, and inspect a sample of variants afterwards. See the related product, location and CSV guides below for the appropriate workflow.
