Matching Deposits/payment between old Brought Forward Sales Ledger Account & Vehicle Debtors on Navigator.
Post receipts against the correct stock number and make as Cash, also use the same reference that was transferred over into Sales Ledger. This will make it easier to allocate down and match in nominal linking.
Post an Invoice/credit note to oppose what you can see in the sale ledger so if minus is showing you will need to post an invoice. The nominal code that you need to use if for the till.
So use 126.96.36.199 New & 188.8.131.52 Used and if by chance one is a demo use 184.108.40.206
You will need to post a Zero Receipt to allow you to Allocate down the Sales Ledger Account.
Go into nominal linking for the tills and allocate down
The end result should be that the Sale Ledger account should be cleared down to Zero or just have a Deposit sitting that were none returnable
