The checkout page is one of the most crucial parts of any WooCommerce store. It’s the final step before conversion, where customers provide key details like billing, shipping, and payment. But what if you need to collect extra information beyond the default fields? Whether it’s a delivery date, gift message, VAT number, or custom note, WooCommerce allows you to enhance your checkout form with custom fields.

Adding custom fields to the WooCommerce checkout page can help personalize the experience, collect essential data, and optimize your order management process. In this blog, we’ll explore the importance of custom checkout fields, the different types of fields you can add, and how to easily implement them using plugins—no coding required.

Why Add Custom Fields to WooCommerce Checkout?

The default WooCommerce checkout only includes standard fields like name, address, email, and phone. However, many businesses need additional fields to meet specific needs. Here’s why adding custom checkout fields can make a big difference:

1. Personalized Experience

You can collect custom information like gift messages, preferred delivery times, or personalization instructions for products.

2. Enhanced Order Fulfillment

Gathering information such as delivery notes, PO numbers, or business IDs streamlines fulfillment for B2B stores and niche industries.

3. Better Customer Insights

Custom questions (e.g., “How did you hear about us?”) help you learn more about customer behavior and acquisition channels.

4. Legal or Regulatory Compliance

In some countries, you may need to collect tax IDs, consent fields, or business registration numbers.

5. Support for Product-Specific Needs

If certain products require extra information (e.g., t-shirt sizes, engraving text), you can apply custom fields conditionally.

What Types of Custom Fields Can You Add?

There’s a wide range of custom field types you can incorporate into your WooCommerce checkout form, including:

  • Text fields – Ideal for single-line input like nicknames or notes

  • Text areas – For longer messages or special instructions

  • Checkboxes – Useful for terms and conditions, opt-ins, or optional add-ons

  • Radio buttons – Allow users to select from multiple options

  • Select dropdowns – Offer predefined options (e.g., delivery time slots)

  • Date pickers – Let customers choose a delivery or event date

  • File uploads – Customers can upload logos, ID proofs, or design assets

  • Hidden fields – Store data without showing it to users (e.g., tracking sources)

Ways to Add Custom Fields to WooCommerce Checkout

1. Use a Custom Checkout Field Plugin

The easiest and most flexible way to add custom fields is by using a dedicated plugin. No coding, quick setup, and full control over placement, conditions, and field types.

Top Plugin: WooCommerce Checkout Field Editor by WPExperts

Key Features:

  • Add, edit, or remove fields on billing, shipping, or additional sections

  • Supports multiple field types

  • Display fields conditionally based on products, categories, or user roles

  • Set required/optional fields

  • Show custom fields in order details, emails, and admin

  • Drag-and-drop field sorting

  • Support for multi-step checkouts

2. Add Code to Functions.php

For developers or users comfortable with PHP, it’s possible to add fields manually using hooks like woocommerce_checkout_fields, woocommerce_after_order_notes, and woocommerce_admin_order_data_after_billing_address. However, this approach is time-consuming and not beginner-friendly.

How to Add Custom Checkout Fields (Step-by-Step)

Let’s walk through how to add a custom field using a plugin like Checkout Field Editor for WooCommerce.

Step 1: Install the Plugin

Install and activate the plugin via Plugins > Add New by searching for “Checkout Field Editor”.

Step 2: Go to the Field Editor

Navigate to WooCommerce > Checkout Form in your dashboard. You’ll see sections for Billing, Shipping, and Additional fields.

Step 3: Add a New Field

Click “Add Field” and choose the field type (e.g., text, select, checkbox). Configure the field label, name (key), default value, and whether it’s required.

Step 4: Set Field Placement and Conditions

Choose where the field should appear (before/after specific existing fields). Optionally, apply conditions—such as only displaying the field when a specific product is in the cart or when the user has a particular role.

Step 5: Save and Test

Save changes, then test the checkout page as a customer. Ensure the field displays correctly, data is collected, and it appears in the order details.

Example Use Cases for Custom Fields

1. Gift Message

Field Type: Textarea
Label: “Add a gift message to your order”
Usage: Collect personal notes to include in packaging.

2. Preferred Delivery Date

Field Type: Date Picker
Label: “Choose your preferred delivery date”
Usage: Allow customers to select when they want the order delivered.

3. Company VAT Number

Field Type: Text
Label: “VAT ID (for business customers)”
Condition: Show only when billing country = EU

4. Special Instructions

Field Type: Textarea
Label: “Special delivery instructions”
Usage: Useful for food delivery, furniture, or special care items.

5. File Upload

Field Type: File
Label: “Upload your design/logo”
Usage: Custom printing businesses, logo orders, ID verification.

Displaying Custom Fields in Admin and Emails

Once the custom fields are submitted, store admins need access to this data for processing. Good checkout field plugins ensure:

  • The data is stored in the order meta

  • Custom fields appear in WooCommerce > Orders

  • Admins can edit or update field values

  • Fields are included in the New Order emails

  • Customers see them in the Order Confirmation Email

This visibility helps reduce confusion and ensures everyone is on the same page.

Additional Features to Consider

If you want to go beyond basic custom fields, consider plugins that support:

  • Multi-step checkout flows – Break checkout into logical steps like Shipping > Billing > Review

  • Conditional logic – Show/hide fields based on user selections or cart contents

  • Field pricing – Charge extra for certain options (e.g., “Add Gift Wrapping – $2”)

  • Field validation – Enforce rules like email format, number limits, or text length

  • Repeater fields – Let customers enter multiple values (e.g., multiple team members’ names)

  • Translation support – Display field labels and descriptions in multiple languages

Best Practices When Adding Checkout Fields

  • Don’t overdo it – Only ask for necessary information to avoid cart abandonment

  • Label clearly – Use simple, user-friendly language

  • Use conditional logic – Keep the form clean by showing fields only when needed

  • Test thoroughly – Try different devices, payment gateways, and field combinations

  • Store and show data – Ensure custom field data is visible in admin, customer emails, and order review

Conclusion

Adding custom fields to your WooCommerce checkout is one of the most effective ways to personalize the customer experience and collect important data. Whether you run a B2B store, a gifting business, or a custom service shop, custom fields can help you tailor your checkout to your business model.

Thanks to powerful plugins like WooCommerce Checkout Field Editor, you can implement these changes quickly, without needing to code. By providing a smarter, more flexible checkout process, you’ll not only boost customer satisfaction—but also improve efficiency and reduce fulfillment errors.
