Client notification of e-file acceptance from IRS

I thought cruise control was a waste of money the first time a buddy of mine had it in his car back in the early '70s. It is sometimes difficult to recognize the utility of something until you have used it. I know that UltraTax has the function for which the original poster inquired. It saved time and worries for me. The function required very little set up, and thereafter without requiring me to take any further action, it emailed the client their return had been accepted, emailing me a copy as well. By UltraTax automatically sending it, I did not have to retrieve acknowledgments, print and mail an acceptance letter, or create an email and send  a PDF. Further, if the return was rejected by the IRS, I as the return preparer got an email notification, again without having to take the extra step of retrieving acknowledgements. Typically for a reject, notice was received in an hour or two and I could quickly address the matter and resubmit the return promptly. As for clients having trust issues, I gather you don't send your clients any acknowledgement that their return has been accepted by the IRS. I for one on the other hand, choose to close the loop: client sends 8879, we receive it and process, the IRS accepts and client is notified. Every tax software has strengths and weaknesses. I for one would like to see an enhancement to Lacerte to add this functionality.
