This module extends the functionality of the Product Availability module (technical name: website_sale_stock) so that for the eCommerce the Available quantity of a product is taken into account instead of the free quantity.
Note that in the past the eCommerce availability was based in Forecasted quantity. This isn't true anymore from version 15.0.
If a product is configured to prevent sales if not enough stock (see configuration section) and its page is accessed in the Website Shop, the availability messages will be based on the Available quantity instead of Free quantity. And also, the eCommerce won't allow you to buy more products than Available quantity (not Free quantity isn't taken into account).
Relation to Odoo 19.0 core
Core 19.0 website_sale_stock uses free_qty (on-hand minus reservations) for eCommerce availability. This module swaps in immediately_usable_qty (Available To Promise — includes incoming moves), which matters for businesses with ongoing inbound supply where incoming stock should be sellable before it arrives.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0In the online shop, product availability messages and purchase limits are based on the 'Available to promise' quantity instead of the 'Free to use' quantity, so customers see and can buy only what is truly available.
This module changes how the Odoo eCommerce shop calculates and shows product availability. Normally the shop uses the free quantity (on-hand stock minus reservations). With this module installed, the shop instead uses the 'Available to promise' quantity coming from the stock availability module.
What changes for users: - On product pages in the Website Shop, the availability message reflects the available-to-promise quantity. - When a customer adds products to the cart, the shop checks that quantity, so it will not let them buy more than what is available to promise. - The same rule applies during the online payment step, so the check stays consistent until checkout.
Where it appears: it works silently inside the existing Website Shop screens (product page, cart, payment). It adds no new menus, buttons or reports.
Which areas it touches: it extends product information (product.product and product.template), the sales order cart update (sale.order), and the website payment controller. The behaviour is activated only in the website context, so back-office stock figures and other sales channels are not affected.
No new configuration options, scheduled jobs or emails are added by this module.
