Caldera Forms is a free, simple form builder with a layout builder that enables you to create the format you want for your form. It is fully responsive and with form processors, it gives you flexibility to handle the form data how you need it.
The integration provides two integrations, one for estimates and another for client creation. Check out the videos below.
You’ll see that estimates are created and that the form entry integrates with Sprout Invoices! Same goes for the client creation form below.
