AR Account

AR Account is the General Ledger Account where the amounts due from the customer will be recorded if an invoice or credit memo is generated from the estimate.  The AR Account drop box lists all active accounts with an account type of "Accounts Receivable".  

At least one General Ledger account with account type of  "Accounts Receivable" is required to use Invoice/Credit Memo. 

After you select a Customer, the customer's default AR Account will appear in this field.
