In running preliminary end of month reports, by trial balance is out of balance and my A/R report does not match the GL.  
 
I have found that it all relates back to an out of balance we incurred when attempting to post sales.  The Trial balance is out of balance by the amount of the AR posted less the amounts posted to Finished Goods, Sales NonTaxable, and Shipping Income.
 
The difference between the AR Aging Report and the AR in the GL is off by the entire amount of the Sales Invoice.
 
What can I do to get rid of these one sided entries that are incorrect?  I would need step-to-step instructions.
 
Thanks for any help.  I'm at a stand still on my EOM procedures until I can get these problems straightened out.
