When invoice number and vendor name are entered, notify if there are existing payments. Allow additional payments if balance is non-zero. Require change to invoice line items and/or additional charges before allowing payment on zero-balance invoice.

No alert per se, but the existing invoice opens to be modified instead of creating duplicate.
