invoice does not reflect payment

SUGGESTED

Hi, I am on 2018 and realized Sage is not supporting this anymore.  I was wondering if anyone would be able to HELP me.  I am generating invoices and KNOW there are payments however, the invoice does not reflect payment and the balance.  -_-

I have regenerate the bill since sometimes it will capture it after that fact.  However I am coming across more and more matters which does not capture the payment.  I do a data validation and rerun....not changes.  Could anyone help???  Thanks in advance
