Hi @fondashci,
Could you first explain what you mean by custom fields? Are these fields you’ve added in some form with an extension?
On the default address fields, those can be changed at anytime by the customer in their My Account page but they don’t update any past orders just in case the details on those past orders are correct.
If you head into a previously placed order you can edit the billing and shipping address fields and use the “Load billing address” or “Load shipping address” link. This will update that info from their saved address.

Hi and thank you for your reply
yes the custom fields are from a plugin
and yes i know that someone can change on my account
the thing is that my customers as we are a small charity they register ones per each year, but in the mean time i added some extra fields details that i want to collect from them.
so i added the plugin with the extra fields and if new customer sign up yes i can see them. But i cant wait until next year for my past customers in order to see the new fields.
So i need something that when i add an extra filed and the customer fill the details needed i would like to see that on any past order on the admin site.
and i try the load billing address but at least in my case dint work.
Hi @fondashci,
Ahh ok, I’ve got it now.
So adding the custom field to your checkout process is just one part of the puzzle here. Now that the field collects data and saves it, you’ll have to customize the areas where you want to retrieve it and show it. So this would be on the individual orders screen, in the My Account area, etc…
That will definitely take some custom work but can be done.
