Does Payflow Link support recurring billing with CiviCRM?
Last I looked into it PayflowLink supported it - but the code integration was not written for CiviCRM.

However, that code was written quite a while ago and I believe that paypal has moved on &amp; now prefers a different interaction with them is used. That might mean adding recurring would create more work. However, I would note that it only changes the nature of the 'development gap' - the short answer is that extra work is required to get recurring payments to work with Payflow Link. If you want to do that work, or commission it then I can help give development advice on it - but you might want to look at whether you are better off using a processor with existing recurring support (e.g. IATS, Stripe, Authorize.net, eway etc). 

Note that if you do look into IATS you should use this link http://home.iatspayments.com/civicrm-referral - if  you are referring yourself you can put the referrer $ to CiviCRM core team I believe
