Custom fields allow you to collect extra data like country-specific tax IDs, notes on how to fulfill orders, or any other information from your customers at checkout. You can add as many custom fields as you want to the standard one-page checkout in your Store.
The information that your customers submit using custom checkout fields appears in the order details and in admin order notifications. It can also appear in invoices and or in your Store's customer notifications. You can make filling out the fields mandatory or voluntary for your customers.
Note
Custom checkout fields let you collect information for the whole order. To gather information for individual items, like custom sizing, see Product Options (Third Party Store).
Available Field Types
You can add the following custom field types to checkout:
Text fields (single-line or paragraph)
Radio buttons
Drop-downs
Date and time pickers
Selection buttons
Checkboxes
It’s up to you to choose which field type best suits the data that you want to collect. For example, you can use date and time pickers for calendars, text fields for delivery instructions or gift messages, and selection buttons for customer feedback surveys.
Add Custom Fields to Checkout
One-page checkout in your Store includes entering an email address, shipping address, and pickup details, as well as choosing shipping methods, pickup methods, and payment options.
