Customer Auto-Registration in Simply Forms lets you automatically create a Shopify customer profile when a guest submits a form.
By mapping form fields such as name, email, phone and address to Shopify customer fields, Simply Forms can associate the submitted information with a Shopify customer instead of keeping it only within the form submission.
How Does Customer Auto-Registration Work?
Simply Forms lets you create custom fields with your own labels and field types. To use those fields for customer registration, you first map them to the corresponding Shopify customer properties. For example:
- First Name → Shopify Customer First Name
- Last Name → Shopify Customer Last Name
- Email Address → Shopify Customer Email
- Phone Number → Shopify Customer Phone
- Address → Shopify Customer default address

When a guest submits the form, Simply Forms can use the mapped information to create a Shopify customer profile automatically.
Why Automatically Register Customers from Forms?
Many forms collect customer information before the visitor has created a customer account.
For example, you might use auto-registration with:
- Contact forms
- B2B account applications
- Product registrations
- Service requests
- Customer surveys or feedback forms
Creating a Shopify customer from the submission lets you connect the form interaction with the customer’s profile and use that customer information in future interactions.
What Happens When the Customer Already Exists?
Customer Field Mapping also helps Simply Forms associate submissions with existing Shopify customers.
This means customer information collected through forms can remain connected to the customer rather than existing only as isolated form submissions.
Once a submission is associated with a customer, merchants can easily access the customer’s profile and related form submissions. As shown in the screenshot below, the submission detail page provides one-click access to the associated Shopify customer and all form submissions from that customer.

Customer Field Mapping Connects Forms with Shopify Customer Data
Customer Auto-Registration relies on Customer Field Mapping to tell Simply Forms which form fields represent Shopify customer information.
Without mapping, a custom field such as Your Email or Contact Number is simply a form field. Mapping tells Simply Forms that the field corresponds to the customer’s email address or phone number.
Customer Field Mapping also enables related features such as Customer Profile Autofill, which can automatically populate mapped fields for logged-in customers.
