Hi I need assistance please:

In the previous fiscal year we generated an invoice for USD (in a foreign currency) $1080.04.  The client paid the amount via a wire transfer and the invoice in Accounts Receivable has the PAID on it.  However, the Accountant said the deposit wasn't posted to the GL.  I didn't think that was even possible!~

He now wants us to do an adjusting entry of:
US Cash Account    1080.04
Accounts Receivable                         1080.04

However, we don't have an Accountants version of Sage so we can't post into a  Linked Account.  I don't want to unlink the accounts because it is a foreign currency and will likely create a data inconsistency.

Could someone advise how best to hand this?  I appreciate you assistance:)  Thanks, Carol
