The information about no ability to return to lower versions should have been communicated BEFORE we upgraded and it was NOT.  Believe me, I called in for guidance before we made this change.  At NO time was I provided information that you have a serious issue with shipping manager. 

Additionally, your new prepayment feature is only half-done.  There is no way to move an online payment or an existing account credit to prepayment.  That is ridiculous.  Now I have the deposits that were taken manually against the sales order done correctly and the deposits paid online or via account credit are done as an AR transaction. Great, now we have a mixed bag so we are very exposed to making a large financial error in our customer accounts.  Fix this mess - you have customers paying huge amounts for this service.  What do you have, one IT tech????
