The PAYPAL Feature should be a MUST on Pay-As-You-Go Pricing. It is DOWNRIGHT DISGUSTING to omit this feature which is widely available on forms all over the internet. Why hold your client HOSTAGE to such a simple feature especially when they are paying customers. That's giving BAD WORD OF MOUTH to an otherwise decent product. Initially your PAYING customers may only have a few applicants per month which do not justify paying a full $39 a month, however, down the road, they may have many more applicants which could justify it. So there is no need to get GREEDY. Think of your customers so they can think about you and your product and TELL THE WORLD ABOUT IT, especially when they are PAYING CUSTOMERS.
Thank you for contacting us. We take questions of pricing very seriously and have considered carefully the impact of our policies on our users. Unfortunately, given the amount of development and support effort that goes into the connector options, we're unable to offer the connectors (including PayPal) to non Professional-level users.
We've floated other ideas in the past (such as a-la-carte pricing for features and a more expensive pay-as-you-go plan) but our research showed little user interest. Please feel free to add your suggestion to our UserVoice page (http://formassembly.uservoice.com/).
If you'd like to discuss this further, I'd be happy to forward you on.
