Does your forms have unlimited fields?

I use Wufoo currently but it's a pain because I have two separate forms I have to send clients because there is a 100 field limit on each form

Yes. Our forms support to have unlimited fields on the form. However, though it is possible the fields on the form would be loaded in the browser at a time when the form is opened which might slow down the performance of the form or sometimes freezes the browser. Also, when you setup conditions on these fields, the respective conditions will be triggered each time the field option is changed which might put an additional load to the browser. It is recommended to have the limited fields on the form to avoid such issues. 

Hope this information helps!
