Associate MULTIPLE SERIAL NUMBERS with a single inventory item?

GOAL: Associate MULTIPLE SERIAL NUMBERS with a single inventory item


  1. We have a single TYPE of Widget. The widget has a QTY of 10. 
  2. Each WIDGET has a different serial #. Thus we have 10 serial #'s since we have a QTY of 10. 
  3. We sell that widget to 10 customers.  (Because we have a QTY of 10 in stock)
  4. Each widget we sell decreases the QTY by 1. We need to associate the item we sold with a customer invoice. So we know WHICH customer we sold WHICH WIDGET to with WHICH Serial #.


Is there a way to handle this natively within Odoo? The only solution I see right now is to create a separate inventory item for every item we sell. So, instead of having 1 inventory item with a QTY of 10 we would have 10 inventory items with a QTY of 1. 

This is bad for two reasons:
1) Reporting - It's not easy to see which customers we sold this widget to in a single view.
2) It's messy. It would be better to have a single inventory item with multiple serial #'s associated with it then many different inventory items with a single serial #. 

Let me know your thoughts on this and how others are handling this!

What you are asking is how Odoo works out of the box.

Single inventory item:

Buy and receive 10 units:

(Click the SPLIT button until you can enter the 3 serial numbers identifying what you received.)

What do you have in stock now?

What are the serial numbers that you have in stock now?

Sell and deliver a Datacard:

Trace the specific serial number from receipt to deliver:


Where (which step) can't you get it to work this way?

I think I must have totally missed this. I am trying your steps now. Thank you VERY much. Will respond to confirm after I have tested.
