Echoing other comments on this post, I too received the "you are requested...." email.  I ignored it.  Yesterday I received a phone call from SecurityMetrics asking me to signup for PCI compliance.  I explained to the caller that I do not take credit card payments; some of my clients pay by card and INTUIT receives card information and payment and then deposits cash into my account.  The SecurityMetrics sales person insisted that I need it.  I ended the call and made a call to QuickBooks Support.  They verified that as my account is not setup for ME to accept card payments I DO NOT need to be PCI compliant.  I have seen elsewhere that if there is an issue, QuickBooks customers should contact QuickBooks and ask them to put  a note on their account record stating they do not need to be PCI compliant and ask them to include notification number ATTN-10602 in the record.
