Create a Advance Billing Credit Memo for remaining 10% and close the sales order. That way Advance Billing is sorted out. Tax is taken care as long as include Advance Billing in Tax setup.
Pay the customer by Misc. AP Payment by entering a clearing account
Adjust the Advance billing credit invoice by entering same clearing account as entered in AP Payment.
No need to create a supplier. Add as Misc. Payment in Payment Entry.
Write-off and Adjustment option under AR to adjust the advance billing credit memo.
Sort of a connection to the original question. Customer decided not to have part of an order so raise RMA to return goods to stock so part of the transaction is credit Goods shipped not invoice. But by doing so we ended up with a credit in Goods shipped not invoice which needs to be manually clear out.
Can somebody help? How can I make it not do that?
thanks
