Customize Your Shopify Subscription Widget Like a Pro with Loop
Your Shopify subscription widget is more than just a feature, it’s a direct extension of your brand and often the first point of interaction for customers considering a subscription.
Think about it: this tiny box on your product page is responsible for turning one-time buyers into loyal subscribers. Shouldn’t it look and feel exactly how you want it?
That’s why we built Loop’s Custom Widget feature to give you full control over how your subscription widget looks, feels, and functions.
In this post, we’ll walk you through:
- Why customizing your subscription widget matters
- What you can do with Loop’s Custom Widget
- How to configure it step-by-step
- Pro tips to get the most out of your widget setup
Let’s dive in.
Why Your Shopify Subscription Widget Matters
Your subscription widget is the exact point when just browsing turns into actually buying - and hopefully, subscribing. However, it is also the point when many brands fail.
If a subscription widget is wonky, off-brand, or confusing, it can undermine trust. And trust is a big contributor to lost sales and churn before a customer even begins.
Here’s a few reasons why your widget warrants extra love:
- It’s the decision point - this is where customers decide to subscribe (or not). Clarity of choice and attractive design = more conversions.
- It reflects your brand – if it does not align with your store look and feel, it seems like an afterthought.
- It affects retention – when customers understand the terms (when they will receive deliveries, subscription benefits, cancellation policy), they are more likely to stay around.
In short: design matters. UX matters. And Loop gives you the power to make your widget truly yours.
Introducing Loop’s Custom Widget (Growth Plan)
The Custom Widget is available for all merchants on Loop’s GROWTH plan or above.
Loop lets you fully design a functional and cohesive subscription experience that aligns with your brand’s principles and aesthetic. No cookie-cutter look. No compromises.
Want rounded corners? A dark theme? Custom hover states? Custom copy like “Join the Refill Crew” instead of “Subscribe & Save”?
It’s all possible with Loop’s custom widget builder.
Where to Find the Custom Widget
You’ll find the Custom Widget builder in the Loop app:
Loop App → Subscription Widget → Custom Widget

Before you start customising, make sure you’ve completed these three prerequisites:
- Set up Selling Plans in Loop
- Map Products to those Selling Plans
- Install the Widget on your Shopify theme
Without these steps, your widget won’t appear on your storefront.
How to Configure the Custom Widget (Step-by-Step)
Setting up your custom widget is super simple. Here’s how to do it:
Step 1: Access the Custom Widget
Navigate to:
Loop App → Subscription Widget → Custom Widget
This is your main customization hub.
Step 2: Activate It on Your Theme
Choose the Shopify theme where you want the widget to appear. Click “Activate”.

Step 3: Customize the CSS
Use the built-in editor to make changes to the widget’s CSS. Tweak:
- Fonts and font sizes
- Button styles
- Colors and gradients
- Padding, margins, layout structure
- Hover states and animations
You can go light-touch or get deep into your brand’s identity—it’s all up to you.

Step 4: Save and Preview
Once you’re done editing, hit Save. Your changes will instantly reflect on your live product pages.
You can go back and adjust things anytime, no need to reinstall or redeploy.
