Using one customer for everything
Recording every order against two customers instead of creating a partner per buyer.
How it works
With this on, every cash-on-delivery order is recorded against one customer and every online-payment order against another. No partner is created for any buyer.
The upside
Your Odoo customer list stays clean, processing is faster, and you do not accumulate thousands of partners who bought once.
The cost
You lose per-customer balances, individual statements, and the buyer's details on the invoice.
How to choose
If you sell retail at volume and offer no credit terms, the pooled customer suits you. If you track balances or sell to businesses, leave it off.
Decide before going live
Changing this later does not rewrite old orders. You end up with part of your history on individual customers and part on the pooled one — a hard state to fix.
Open Configuration
The setting is on the Customer tab.
