Hello everyone,

I'm working with Odoo 18 and I'm facing an issue with sales order confirmation. Currently, I can create and confirm a new sales order for a product even when its stock quantity is zero. Odoo allows me to move forward with the quotation, but this is causing problems with overselling.

I need a way to prevent a new sales order from being confirmed if a product on that order has no stock.

I've already tried to change the settings based on common solutions, but the options I'm seeing don't seem to be the ones I need.

• I looked in the Sales app under Configuration > Settings, but the only options I see are related to shipping policies ("send products as soon as possible" and "send all products at once").
• I also tried to find a setting in the Inventory app under Configuration > Settings, but I couldn't find a "Picking Policy" field with options like "As soon as possible" or "When all products are ready." The options I'm seeing are different.

Could someone please guide me on where to find the correct configuration to achieve this? Is there a specific setting, a module, or a customization needed to block sales orders with zero-stock products?

Thank you for your help.
