title: Distributing free ios apps privately to multiple customers (b2b?)
body: <p>I have been researching a lot about this issue, but I only get more and more confused...</p>
  
  <p>Basically, what I need to do is to distribute a free ios app, but I don't want it to be available to everyone, but just to some of my customers (5 or 6 companies). I have been looking into the B2B option, but I have some questions:</p>
  
  <ul>
  <li><p>The purchasing company must enroll in the Volume Purchase Program... will this be free for them?</p></li>
  <li><p>Can I distribute the same app to more than one company? </p></li>
  <li><p>How exactly can I perfom the distribution? Can I just publish my .ipa through one of my servers? Or do I need to go with a MDM? I have read that it is actually the purchasing company who has to get and manage the MDM?</p></li>
  <li><p>According to Apple : "Even though custom B2B apps can be free, you must have a Paid Applications contract for your app to be visible on the Custom B2B App Store."... what does that mean?</p></li>
  <li><p>Maybe there is another better option for me than the B2B program?</p></li>
  </ul>
  
  <p>Sorry for asking so many questions, and many thanks in advance!!</p>
