  • How to keep tabs on inventory levels in Shopify’s backend, ensuring you always have sufficient stock.

How to Add Quantity On Shopify Back End (To Keep Track Of Inventory)

Stock shortages are a big problem for ecommerce businesses, with research warning that:

  • 73% of consumers feel less loyal to retailers after experiencing product unavailability
  • 59% feel less confidence to keep shopping with a retailer if they experience continual stockouts

So it pays to keep close tabs on your stock levels.

Of course, Shopify already tracks product inventory automatically. But there might be times when you need to manually change those figures to give an accurate reflection of your real-world stock levels.

There are a couple different ways you can do this through Shopify’s backend…

Adding Quantity to Products in the Shopify Admin

Adding quantity to products in the Shopify Admin.

Follow these steps to change inventory quality via your Shopify admin dashboard:

  • Click Products.
  • From the expanded menu, choose Inventory.
  • Use the up and down arrows to alter stock level, or enter a number in the box.
  • Don’t forget to save your changes!

Adding Quantity With a Barcode Scanner

If you’ve got a barcode scanner, you can use it to scan product barcodes and manage your inventory via mobile or tablet.

There are actually two ways you can manage stock levels using your barcode scanner:

Increase Inventory Quantity By One

This approach couldn’t be easier:

  • Navigate to Products within the Shopify app.
  • Select Inventory scanner.
  • If relevant, choose your inventory location.
  • Scan the product barcode.
  • Save your changes.

Adjust Quantity By a Specific Amount

Sometimes, inventory management is a little more complex than just adding one item to your stock levels.

Follow these steps to adjust your product quantity by any other amount than +1:

  • Navigate to Products within the Shopify app.
  • Select Inventory scanner.
  • If relevant, choose your inventory location.
  • Scan the product barcode.
  • Tap the product in question.
  • Enter the increased or decreased volume level in the Adjust field. For instance, if you want to decrease inventory quantity by 10, you’d enter “-10.”
  • Tap Done.
  • Save your changes.

Adding Quantity With an Inventory Import

If you don’t fancy doing all the tinkering within Shopify’s backend, you can make the changes within a CSV instead.

First, you’ll need to download your current inventory levels, as follows:

  • Go to Products > Inventory.
  • Click Export.
  • Select the rows you wish to export.
  • Specific whether you’re downloading from one or multiple locations (if relevant).
  • Click Export inventory.

The next step is to trawl through the CSV file, manually altering stock levels as required.

Note: If the CSV contains location columns for which you don’t want to change the inventory, delete the columns (including the headings) for those locations.

If you need some help identifying the relevant product, read Shopify’s explanation of the inventory CSV file format.

Having updated your stock levels, it’s time to upload the CSV to update and overwrite inventory quantities in Shopify’s backend. Here’s how:

  • Navigate to Products > Inventory.
  • Click Import.
  • Select the relevant CSV.
  • Click Import inventory.
  • Verify the information you’re importing.
  • Click Start import.

How To Display and Promote Limited Quantity On Shopify to Capture More Sales

Our first two methods for adding quantity on Shopify are about user experience and inventory management, respectively.

But our third and final method is all about leveraging product scarcity to boost Shopify conversion rates.

Promoting limited-quantity products is a highly effective way to drive immediate action from would-be customers.

Because they’re more likely to convert here and now if your stock levels are running low.

Of course, people browsing your Shopify store can’t take a peek at your backend. If you’re low on stock, you need to tell them.

Here’s how to do it without code using the Shopify Dawn theme (N.B. other themes may also support this feature):

  • Visit Shopify Admin > Themes.
  • Click Customize for the theme you’re working on.
  • Navigate to the product page.
  • Under the Product information section, add the Inventory status block.
Inventory status block.

Here’s the Inventory status block, with options for inventory threshold:

Inventory status block with options.

Bear in mind that if you don’t check the Show inventory count box, it’ll just display a “Low stock” message.

But that’s not all you can do.

To really drive home product scarcity, try wrapping the message in a product badge, like in this example:

Product badge showing quantity.

Adding a badge really makes the low-stock message stand out on the product page, which means visitors are more likely to notice it — and, hopefully, take action.

How Does Shopify Handle Out-of-Stock Products?

Shopify considers a product to be out of stock when the inventory level reaches zero (or below).

By default, Shopify doesn’t let customers buy out-of-stock items until inventory returns to a positive level.

However, you can allow purchasing on these items from within the Inventory section by enabling the setting Continue selling when out of stock.

Inventory section setting - Continue selling when out of stock.

Use this approach when:

  • You want customers to be able to pre-order the product.
  • Shopify’s data doesn’t represent your real-world inventory levels.
  • You know stock is incoming and you want to keep selling before it turns up.
  • You’d rather sell first and order extra stock later.
