WooCommerce Attribute Stock supercharges your stock by allowing you to share inventories between multiple products/variations, or deduct different amounts of stock for each purchase of a product, variation, or attribute.
Easily track and manage shared product stock, variable stock, linked stock, product addons, product combos, parts, measurements, ingredients, and much more!
First, a short message and friendly warning <3
Since Attribute Stock was released in early 2020, when no other plugins offered this level of stock control, several competing plugins have popped up over time, as one would expect. They range from offering a subset of features from Attribute Stock to shameless clones of our plugin (looking at you “Shared Attribute Stock“).
Please don’t be fooled by some of these plugins, especially from WooCommerce.com. These are not official WooCommerce plugins. They are developed by 3rd parties and are often of poor quality. The only requirement by WooCommerce.com is to pass their automated testing suite, but this doesn’t ensure quality control or prevent against errors, poor UI/UX, or unhelpful support.
We continue to stand by the quality, performance and extensive feature-set of Attribute Stock, while offering it at a fraction of the cost of competing plugins. We are a small independent developer and we make plugins because it’s what we love doing. When you contact us for support, you’re speaking directly to the people who make the plugin, not a support agent or company representative.
With that said, we’d like to say a huge thank you to everyone for your kind words, invaluable feedback and amazing support over the years!!! <3
Why would I need this?
Let’s say you have an online store that sells custom printed t-shirts, with each t-shirt print listed as a product on your site. Simple enough, right?
Not exactly… Since WooCommerce can only track stock at the product level, there’s no way to keep track of the total number of blank t-shirts you have in stock between each of your products.
Your stock levels would quickly go out of sync and your customers would be able to purchase 10 different prints even if you only have one t-shirt left in stock!
How does attribute stock fix this?
By adding stock to global product attributes, you can effortlessly share one or more inventories between any number of products or variations that have these attributes.
Shared stock levels are accurately tracked, available stock is displayed to customers, and over-purchasing is prevented.
This example barely scratches the surface of what’s possible. Make sure to check out all of the features and examples below for more advanced use cases.
Attribute-based stock
Manage stock at the attribute level. Share stock between all products/variations with one or more assigned attributes.
Limit product stock
Display the effective product stock available to customers on the frontend and prevent over-purchasing.
Quantity multipliers
Deduct different quantities of attribute stock or product/variation stock per unit. Useful for measurements, weights, packs, lengths, etc.
Product filters
Add filters to your attribute stock to match only specific products, product types or product categories.
Stock management
Admin page for easy management of attribute stock items. Set SKUs, internal notes, low stock threshold, product filters, and more.
CSV import/export
Instantly export your attribute stock to CSV. Add or update stock in your favorite spreadsheet editor, then import your changes with a single click.
Stock reports
Keep track of your attribute stock with WooCommerce stock reports.
Low stock emails
Receive email notifications for low stock and out of stock attributes.
REST API
Manage your attribute stock from external software with our fully integrated WooCommerce REST API endpoint.
Highly compatible
Works well with many plugins, such as Variation Swatch plugins, POS systems, Subscriptions, Product Bundles, Waitlists, Cart Stock Reducer, WP-Lister, WPML, Polylang, and more.
Developer friendly
Almost anything that can’t already be configured can be added or changed with actions and filters.
* Please note that WordPress Multisite and multi-store synchronisation is not currently supported or planned.
Example #1 – Variable stock
You have a candy shop and sell candy in bags of 10, 25, and 100. Simply set your total stock at the product level and specify a Stock multiplier on each of your product variations (demo). The respective amount will be deducted from your total stock for each purchase. If you need to share variable stock across more than one product listing, you can use an attribute stock item instead (demo).
Example #2 – Multiple attributes
Often your stock will have more than one attribute, such as t-shirts with different sizes and colors. In this case it’s trivial to create an attribute stock item with rules to match any number or combination of attributes and attribute terms (demo).
Example #3 – Product bundles
Sometimes you’ll want to sell several simple products as well as a bundle of these products for a discount. Since attributes can be assigned at the product-level as well as the variation-level, you can easily create and manage stock that’s shared between a product and a variation of a different product (demo).
Example #4 – “Any” variations
Attribute stock doesn’t require you to specify each of your product variations explicitly, like you’d normally need to do when managing stock on variations. If you have product variations that share similar data like price and weight, you can simplify your product by grouping them into a single variation with Any selected for its attribute(s). Stock will be accurately handled for each attribute according to your attribute stock rules (demo).
