I made a form builder that works very well for e-commerce websites. Already made native BigCommerce but working on Shopify extension, though you can make it work easily with any of them by just embedding a code. There is a powerful upload field, built in SMS alerts, abandoned form recovery, and much more. Check out my [form builder – MightyForms](httpa://www.mightyforms.com) and let me know your thoughts. Thank you!
