Create a Custom Shopify Registration Form in Minutes with Primy

Why do you need a custom registration form for your Shopify store

Ever noticed how Shopify’s sign-up process barely asks for any customer details beyond an email? From what we’ve seen, it’s designed to get customers in quickly, but that convenience often comes at the cost of missing valuable data. And if you’re still using legacy accounts, it only asks for a password, too.

This low-friction flow might seem helpful at first, but it leaves many store owners blind to crucial details that could make all the difference for personalized marketing and premium customer service.

Here’s why adding custom fields can really help:

• Personalisation – Being able to greet shoppers by name in order to update, cart recovery, or loyalty campaigns creates a warmer experience.
• Segmentation – Adding tags like “wholesale” or “VIP” right at sign-up means customers flow automatically into targeted email or SMS campaigns.
• Compliance – Having a simple consent checkbox keeps you aligned with CASL, GDPR, and anti-spam laws from day one.
• SMS marketing – Want to grow SMS subscribers? A phone number field with proper opt-in gets you ready for SMS platforms like Postscript or Attentive.
• Customer service insight – Extra details like company name or birthday can speed up support queries or help with special offers.

Why Shopify Forms Falls Short for Custom Registration

We get why many merchants start with Shopify Forms—it’s free, built-in, and simple. You can drop a pop-up or inline form onto a page and collect basic details like name, phone, or birthday.

But once your needs grow, this simplicity quickly feels limiting. Here’s what we’ve seen as common frustrations:

• Limited to 25 fields and single-step forms. Great for quick signups, but forget about longer forms like wholesale applications or onboarding quizzes.
• No multilingual support. Want to serve customers in multiple languages? Shopify Forms won’t sync with Translate & Adapt.
• No conditional logic. Merchants tell us it’s frustrating that you can’t hide or show fields based on customer responses.
• Locked styling. Because of the Shadow DOM setup, customizing the form design to match your brand is anything but easy.

We’ve talked to many brands who ended up switching because Shopify Forms simply didn’t let them collect the data they needed. That’s why we built Primy—to give you the freedom to design forms your way.

Building a custom register form with Primy Form Builder

At Primy, we’ve worked with enough stores to know exactly where default forms cause friction. That’s why our Form Builder↗ focuses on flexibility without adding complexity. Beyond offering features that give you unlimited possibilities for customization, you’ll also benefit from built-in spam protection to prevent unwanted signups—learn more about how we help prevent Shopify form spam →↗.

Here’s what you can easily do with Primy:

• Add any field you need: From dropdowns to date pickers, checkboxes to text fields, the options are there.
• Match your theme: Use built-in styling controls to make forms look like part of your store—no coding required.
• Conditional logic built-in: Want to show extra fields only for wholesale customers? Easy.
• See submissions alongside customers: Form responses live inside your Primy dashboard and sync with Shopify Customer records.
• Integrate with your tools: Want to push contacts to Mailchimp or other tools? That’s built-in too.

Setup your way:

• Use a drag-and-drop builder to build from scratch or AI-powered suggestions to start quickly.

Display your way:

• Inline forms embedded on your store without touching Liquid.
• Pop-ups are triggered by behavior, like exit intent or time on page.

With Primy Form Builder↗, we make sure you spend less time setting things up and more time collecting meaningful customer data.

Connecting your form to Shopify Customers

We built Primy Form Builder↗ to keep your Shopify Customer records as the single source of truth. You can decide how each form submission interacts with your store:

• Create a customer silently—great when you don’t want to prompt account creation yet.
• Create and invite the customer—perfect for stores using Shopify’s new accounts.
• Create with a password field—ideal for classic account flows.

We also made sure you can update existing customers without duplicates. And because we know tagging is crucial for segmenting lists, you can auto-assign tags based on form responses, like tagging VIP registrations automatically.

Receiving email notifications for new registrations

No one wants to keep checking the Shopify Admin. That’s why Primy↗ helps you stay informed effortlessly. That’s why Primy sends real-time email notifications for every signup.

Here’s what you get:

• Send notifications to multiple team members.
• Customize subject lines and content with dynamic tags.
• Automatically include all form responses.
• No Zapier or code required.

Sending an automated welcome email to new customers

With Primy↗, we also made it easy to welcome new customers instantly, without needing Klaviyo or Mailchimp.

Just toggle on the built-in welcome email:

• Customize the subject and body with customer details.
• Use dynamic tags to show personalized info.
• Match the style to your brand using the rich text editor.
• Skip the hassle of third-party tools—it’s all inside Primy.

We hear from brands that this small step improves the first impression and encourages faster engagement post-signup.

Summary and next steps

We’ve seen it across hundreds of Shopify stores: default forms are easy to start with, but quickly become a bottleneck for growth.

Primy Form Builder↗ exists because we wanted to solve these common frustrations—giving merchants a no-code, flexible way to capture the customer details that matter most.
