WooCommerce: View Stock History @ Product Admin

When questions such as “How do you save the product stock inventory history?” pop up in our private Bloomer Armada slack channel for WooCommerce developers, I can’t really do without thinking of coding it myself!

This neat customization saves the stock quantity of a simple product or a variable product variation before there is a stock change, due to a manual stock quantity edit or a customer order.

Please bear in mind that if you have hundreds of stock movements per product this may slow down your backend and/or database, so the snippet may need some sort of optimization or limitation (“last 10 movements”).

So, let’s see how it works. Enjoy!

The snippet below works also for variable products (as well as simple ones). The new “Stock History” meta box will show at the bottom of the Edit Product page, and if the product is variable it will give a stock movements report for each variation. Each line corresponds to a stock quantity edit, whether this is due to a manual action by the store manager or a customer order. The last line always returns the current stock value.

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.

    Is this putting a lot of stress on wordpress?

    1. Only if you have thousands of products and a lot of stock changes, in which case this needs to be recoded and maybe use custom DB tables
