I work with a construction company that charges a whole months invoices to the vendor and also returns items for vendor credit.  At the end of the month, we pay that vendor with our credit card.  Now, when I take a credit card payment to post and apply the invoices paid, it works well.  But, when I have vendor credits, it does not work.  For instance, I paid the vendor the month amount due of 24K, I have 29K in invoices and 5K in vendor credits, I can't get it to tie back to the 24K.  It adds the vendor credits back into the total even though when applying invoices, the vendor credits state "vendor credit".  Is there any way to make this work besides going to every invoice and marking it paid?
