We've been so happy with Jotform, not only as our form building software, but also their affiliate program. It pays much higher than other form building affiliate programs and their affiliate team is really responsive on the few occasions we've had questions. In fact, we were the top referrers for another form building company but switched to Jotform after really terrible experiences with payouts and customer service. Couldn't be happier with Jotform! We average sending over about 100 signups a month and it's not a hard sell in the least because Jotform has both a free and an affordable program perfect for the small business we work with.
