we decided to do it in house, since ACS was part of suite success package. I thought they will be a helping hand since I am tied up with many other applications beside Netsuite because my team manages all the enterprise application. I was catching their mistakes and showing them what to do, since I have to do all the work what is point in having them. I can use that money to hire coders for scripting if needed. Thank god last year I declined an offer to join NS as ACS Solution architect.
