Create a credit memo

Hi All,

I have an invoice which a user created for $114.50 which was made of $104.90 as the line and $10.41 as the Tax.

The user then went and created a receipt for $105.60 which was made of $104.09 as the line and $1.51 as the Tax

Now the remaining $8.90 needs to be credited as the customer is not going to pay this amount. The problem is in the invoice details the balance $8.90 is showing as Tax which needs to be credited. How can this be done by creating a credit memo.

Screen shot is attached.

Waiting for some answers

Thanks

Jay
