GET THIS FORM BUILDER.
Cannot recommend this form build enough. I was able to build a form from scratch using push and get calls to and from Salesforce with custom and standard objects in a week where specialist Salesforce agencies and developers failed to in over 6 months. After that we have had lots of refining to get a really professional and polished product. Our only limitation is our own team - now we love it so much we are trying to think of all the new things we can streamline using this form builder.
Benny has been a huge help and his support hours are well worth investing in, though he is so passionate about the tool he very often helps for free if he can quickly.
I work in a highly regulated industry where data integrity is hugely important and this has helped us offer our customers an excellent service and improve our data quality. For the first version of our form alone it will save over 1,000 human hours p.a.
I highly recommend using this tool over any other, the interface is easy and intuitive, they are constantly making updates and improvements and it just works!
