I agree, it looks very unprofessional.  I'm not taping anything, just folding and refolding to get the address to set correctly.  I agree that this should not be a problem for Quick Books to fix.  People will be migrating to ACH's soon and then we won't need the checks nor the envelopes soon. I'd rather not go to ACH. I am old school and like calculating the time it will take the checks to arrive and have those check numbers ready if anyone calls about payment.  Please fix this soon Quick Books!!
