I currently use Wufoo to implement forms for over 20 Website Clients. I have over 40 forms in use currently ranging from basic contact forms to complex custom ordering forms. We choose to start using Wufoo back in February 2012 after searching for a solution that allowed us to incorporate PayPal Payment with customized order forms. We need to collect very specific user information for a particular client's educational workshops and Wufoo offered us the best solution. We also use the custom reports to provide clients with monthly and annual sales reports which they love. We have used Wufoo to create simple contact forms, surveys, event RSVP, livestock show entry forms w/payment, farm market order forms w/payment, daycare employment applications, education workshop registrations w/payment, and more. I have had a few technical questions and I received direct email responses and dialog with the same support staff person to resolve or answer my question.
Overall, Wufoo have been a huge benefit to our business as it provides us a way to create customized solutions for clients in an easy package.
