The form did what I needed it to do exactly and it was easy to connect my metafields to the form. I wanted some customization help in making the first dropdown field blank for a required selection and Giacomo made it easy, and gave me the tools to make that change when I needed to do it again.

Did exactly what we needed and the customer service was fantastic.

This application met my needs for creating the text fields I required. Agent Giacomo helped me do it quickly, with great patience and professionalism. A big thank you to him!

— DEBRICO

I chose this plugin to integrate the tax code as a necessary field during registration and within the user profile in Shopify because I need it to issue an invoice. It works perfectly, solving my problem and giving me full control over registration and login.

This app is fantastic and has helped me save an additional field I needed for customer registration. You can also add your own scripts to customize it however you like. Thanks to the developer!

Obwohl ich die AÖp deinstalliert habe, wurde eine Zahlung eingezogen. Ich finde keinen Kündigungs Button und per E-Mail erreiche ich auch niemanden. Ich bitte dringend darum, dass ich jkontaktiert werde und der "Vertrag" aufgehoben wird.

We have 50,000+ customers so it would only allow us to use the PRO PLAN. the pricing plan should be based on the amount of customers using the app and not the amount of customers that signed up prior to the installation of the application. The plan states "Store additional data up to 10,000 customers" Well what if I only want to store data for our VIP members that only consist of 100 customers?

— KewbzUK

New to the app but it's perfect for adding custom fields to the registration form. Plus support was really quick and helpful when I was trying to get some customizations going!

— Free Food for Millionaires!

We were looking for an app that could allow us to input customer fields in the customer registration page and this worked perfectly! We were using shopify 1.0 so the auto-placement didn't work for us, but the live chat staff replied us so quickly, taught us how to go about it and we eventually managed to input the fields in! :)

This Shopify app has significantly streamlined our customer data management process. We primarily use it to store important information such as customer birthdays in metafields, and it does so seamlessly. What really stands out is the exceptional support provided by the team behind the app. They are incredibly responsive and helpful whenever we need assistance. In short, I highly recommend this...

This plugin solves my big problem! I like it

— Songmont

A must-have for Shopify! User-friendly interface with a multitude of customization options, it was also really easy to implement with the tool that helps you check if the code implemented is correct.

— Goof Store

an absolute 10/10 app! This took care of exactly what I needed to get done. The support also went beyond my expectations. Extremely helpful on all levels from the support and they will be sure to get you right!

— TXF Light Source

L'app funziona molto bene e soddisfa i requisiti richiesti per questo tipo di applicazione. Noi la utilizziamo per aggiungere dei dati di registrazione del cliente al nostro sito quale ad esempio la data di compleanno
