Don’t buy the plugin if you’re interested in the file upload feature. It’s subpar. I couldn’t get the file uploads to show in the order, order email or the order in the customer account. No way to see if there is a file associated with the order. It does upload the file to your server but again, no way to figure out what order it’s associated with. I first tried the WooCommerce Checkout Manager plugin which was free (and I do like the uploaded file interface). It worked much better but it had a small issue with not being able to use the upload button within the customer account. I thought purchasing a different plugin would assure a better product, but sadly not with regard to the upload feature in the Flexible Checkout Fields plugin. However, this Flexible Checkout Fields plugin works great for changing the existing fields and adding in new areas.
Nevermind, it’s fighting against the quotes plugin I have installed.
