Within my buisness I frequently have consultation with customers where I fill out their details and requirements on a paper form then add them as a contact to zoho books. I was wondering if there was a way of creating a digital version of this form that once submitted would create a contact and save all their requirements under their profile or as a lead? 

I have managed to create the form on zoho creator however the it now tells me a need to upgrade and I'm too sure it will work if i pay more.... please help!
