WooCommerce is a powerful eCommerce platform, but it does not always provide everything you need to collect detailed customer information or offer product customization. This is where custom fields become essential.
By adding custom fields, you can allow customers to personalize products, request specific services, or provide additional details during checkout. This improves user experience and helps you run your store more efficiently.
In this guide, we will cover two key areas:
- Adding WooCommerce Custom Fields to Products (Product Addons)
- Adding custom fields to the checkout page
1. Adding WooCommerce Custom Fields to Products (Product Addons)
To add custom fields to product pages, we will use the official extension:
Product Addons and Custom Fields Manager for WooCommerce
This plugin allows you to create advanced product options and personalization fields with ease.
Why Use Product Add-Ons
Product add-ons help you:
- Offer personalized products
- Upsell additional options
- Increase average order value
- Improve customer experience
For example:
- A bakery asking for custom cake text

- A gift store offering wrapping options

This keeps your product page clean and improves usability.

This improves user experience and keeps checkout clean.
