Is this possible ?
Hello @LitteDear !
When it comes to adding notes to the checkout, it is not something that can be done as there is very limited customization on the checkout, and anything beyond that is only possible on the Shopify Plus Plan.
Why are you looking to add a notes section to the checkout? An alternative for you might be to have it added to your cart page, where customers will be able to add the notes before they checkout. It would look something like this:
I have a full guide on how to enable cart notes for you here. As you will see at the top of the guide, if you’re using a free Shopify theme such as the Simple theme, then our support would be able to help you enable this using 15 minutes of your Design Time.
If the above option does not suit you, please tell me a little bit more about your business and your products, that way I might be able to help you find a better alternative!
Let me know if you have any other questions.
Thanks! -Lana
