+1 on this... I&#x27;d say do a 30-day trial period, then around day 25 ask for billing information...  If you have tracking&#x2F;analytics in place you know how many users are returning once signing up, and you have a better indication of conversion after use.<p>If you&#x27;re going to have a free tier, I&#x27;d say limit it to N service integrations (3-5), but definitely make your core users paying close to the start.<p>If I had a need for something like this day to day, I&#x27;d definitely pay... Actually, I&#x27;d suffer for a while, then try it, then suffer again, then pay... but that&#x27;s me and I&#x27;m kind of cheap&#x2F;frugal.  Most people will start paying once they see and feel the value.<p>Also, it&#x27;s much easier to field requests from a few hundred paying users than thousands of non-paying ones.  It&#x27;s very hard to do conversion from free after the fact... many businesses have failed, burned, burned out, and left their best (paying) users in a lurch following this model.
