Have been negotiating an LOI for the past 60 days. We're finally in agreement except for customer interviews, which the seller is refusing to because he fears they will disrupt the business and is not willing to take on that risk prior to closing.   
I know they're  important because: (i) they confirm clients are happy, committed to the company - the steady sales confirm this and (ii) provide potential growth ideas - we have somewhat identified those already. To those of you out there who have completed an acquisition, how useful / important did you find them?
