Hi Ahmad safi,

W.r.t your query, I have gone through it and tried to replicate it. Few recommendations which I would like to suggest you which might cater to your needs are as follows:-

1)In Odoo, Accounting Invoices are a part of Sales Order

2)As you sell products through Accounting Invoices hence, it would not contain anything related to Delivery Order of the Product.

3) Due to this no stock level would be maintained based on your Invoices by default. For your requirement customization would be required to enable that functionality.

Hope it helps

Your stock will be reduced at the Sales Order level. For your purposes it seems like you may want to change your invoicing behavior from "Invoice ordered quantities" to "Invoice delivered quantities". This can be performed from the Sales>Configuration>Settings>Products menu. Note that each individual product will have this setting as an attribute, so if you have already created products prior to changing this setting you will need to modify them manually on the product page.

Can you include more information on how you would like your workflow to operate if the above solution is insufficient?

Cheers,

Joseph Wright
