Print-on-demand (POD) products are no longer limited to standard designs. Today's customers expect to personalize what they buy—whether that's adding a name to a tumbler, uploading a photo for a phone case, choosing a font for a poster, or creating a one-of-a-kind gift.
While Shopify makes it easy to launch a POD business, its built-in product options are designed primarily for simple variants like size and color. If you want customers to upload artwork, enter custom text, choose colors, or preview their personalized products before purchasing, you'll need additional product customization options.
In this guide, you'll learn how to add product customization to print-on-demand products on Shopify using both Shopify's native functionality and a more flexible no-code solution. We'll also show several real-world POD customization examples that you can build for your own store.
Key Takeaways
- Product customization allows customers to personalize POD products before checkout.
- Shopify's native functionality can collect basic customization details through line item properties.
- Product options apps support advanced customization features such as file uploads, image uploads, live previews, conditional logic, and add-on pricing.
- For most POD stores, Easify Custom Product Options is the simplest way to add all of these capabilities — it offers a Free Forever plan, so you can start customizing products at no cost.
What is Product Customization for Print-on-Demand Products?
Product customization allows customers to personalize a product before it is produced. Instead of purchasing a standard design, shoppers can modify different aspects of a product to create something unique.
For print-on-demand businesses, product customization commonly includes:
- Custom names
- Initials or monograms
- Personalized messages
- Image uploads
- Logo uploads
- Artwork uploads
- Font selection
- Color selection
- Image swatches
- Custom sizes or dimensions
For example:
- A customer buying a custom tumbler may add their name and choose a font.
- Someone ordering a phone case may upload a family photo.
- A business purchasing branded apparel may upload a company logo for printing.
- A customer ordering a personalized poster may upload artwork and enter a custom quote.
Rather than collecting this information through emails after an order is placed, merchants can display customization fields directly on the product page. This creates a smoother shopping experience while ensuring production teams receive everything they need to fulfill the order accurately.
How to Add Product Customization to Print-on-Demand Products on Shopify
There are two common ways to add product customization to Shopify.
The first uses Shopify's built-in functionality and is suitable for simple personalization. The second uses a dedicated product options app, making it easier to create more advanced customization experiences without editing your theme.
Method 1: Using Shopify's Native Features
If your products only require simple personalization - such as customer names, engraving text, or short messages - you can use Shopify's built-in line item properties.
This approach requires a small amount of theme customization but doesn't require installing an app.
Step 1: Open Your Theme Editor
From your Shopify admin, navigate to: Online Store → Themes → Edit code
This opens your theme files where you'll add the customization field.
Step 2: Select the Default Product Template
Locate the product template used by your theme.
Depending on your theme, this may be Default Product. Choose the template where you want the customization field to appear.
Step 3: Add a Custom Liquid Block
Inside the product template, add a Custom Liquid block.
This allows you to insert your own HTML and Liquid code without modifying other parts of the product page.
Step 4: Insert the Customization Field Code
Paste the following code into your Custom Liquid block.
<div class="personalization">
<label class="title">Personalization</label>
<div class="input-wrapper">
<input
type="text"
id="personalization-input"
maxlength="12"
placeholder="ZOE"
>
<span class="counter">
<span id="char-count">0</span>/12
</span>
</div>
<p class="note">Maximum number of characters: 12</p>
</div>
<style>
.personalization {
max-width: 500px;
font-family: Arial, sans-serif;
}
.personalization .title {
display: block;
font-weight: bold;
font-size: 18px;
margin-bottom: 10px;
color: #222;
}
.personalization .input-wrapper {
position: relative;
}
.personalization input {
width: 100%;
height: 44px;
padding: 0 70px 0 12px;
border: 1px solid #ddd;
box-sizing: border-box;
font-size: 16px;
}
.personalization input:focus {
outline: none;
border-color: #999;
}
.personalization .counter {
position: absolute;
right: 12px;
top: 50%;
transform: translateY(-50%);
color: #999;
font-size: 14px;
}
.personalization .note {
margin-top: 8px;
font-size: 14px;
color: #666;
font-style: italic;
}
</style>
<script>
document.addEventListener("DOMContentLoaded", function () {
const input = document.getElementById("personalization-input");
const count = document.getElementById("char-count");
if (input) {
input.addEventListener("input", function () {
count.textContent = this.value.length;
});
}
});
</script>
This creates a basic text field where customers can enter personalization before adding the product to their cart.
Because the field uses Shopify's line item properties, the submitted information will automatically be attached to the order.
Step 5: Save Your Changes
Save and preview your storefront.
It's a good idea to place a test order to verify that:
- The field appears correctly.
- Customers can submit personalization.
- The information is displayed inside the Shopify order.
Method 2: Using Easify Custom Product Options
If your print-on-demand products require more than a simple text field, Easify Custom Product Options provides a no-code way to create advanced product customization experiences.
Step 1: Install Easify Custom Product Options
First, install the app from the Shopify App Store and finish the basic setup to start creating custom product options.
Step 2: Create an Option Set
Open Easify Custom Product Options and create a new Option Set.
An Option Set acts as a container for all of the customization fields you want customers to complete before purchasing.
Step 3: Add Product Customization Fields
Next, add the customization fields your products require.
Some of the most common options include:
- Text Box
- Text Area
- File Upload
- Image Upload
- Dropdown Menu
- Color Swatches
- Image Swatches
- Font Selector
If you're primarily collecting names, monograms, engraving text, or gift messages, you may also find our guide How to Add a Personalization Option to a Shopify Product helpful, as it covers these common personalization fields in greater detail.
Step 3: Assign the Option Set to Your Products
Once you've finished creating your customization fields, assign the Option Set to the products or collections where it should appear.
Step 4: Save and Preview
Save your changes and preview the product page.
