Customer payments for intercompany orders
When you post an intercompany customer invoice, the system creates a customer transaction. The customer transaction is open until it's paid. Then, the system creates a vendor transaction that matches the customer transaction when you update the corresponding intercompany purchase order invoice. The vendor transaction is open until it's settled. You can have the system create and post an accounts receivable payment journal automatically when you post the accounts payable payment journal.
To do so, follow these steps:
Go to Sales and marketing > Customers > All customers.
Select your customer account.
On the Action Pane, select the General tab and then select Intercompany.
Select the Sales order policies tab.
In the Payment journal field, select the accounts receivable payment journal that the intercompany vendor payments are registered to.
If you want the system to post your journal automatically, turn on the Post journal automatically field by selecting it.
