I can think of a way that you may consider doing, Marie_FMI.

Updating your customer's address or company name will automatically update all the previous transactions. Thus, I'll send this feedback to our product engineers so that they can take a look at with this

Alternatively, let's keep the old billing or shipping address of your customer or vendor. 

Before updating your customer's address, you can enter the old one in the Notes field of the Customer Information page.

This way, you'll be able to keep the old address and update a new one.

Iv'e added a sample screenshot below:

The updated customer's address will only generate for the future invoices.

If you have any follow-up questions, just post it right away. I'll be here to help you out.

Thank you for your response, however when updating an address in the customer information it changes all orders, past and present. I really need to keep all of my past orders showing the address that was used at the time the order was sent.

It's nice to hear from you again, Marie_FMI.

I can think another way that you might consider doing. You can enter your customer's new address in the Notes field instead of the old one.

You can take a look at the screenshots below.

You'll have to manually copy the new address from the Notes field and paste it in the Bill To or Ship To field. This way, you'll have an updated address when creating a new transaction. 

Click the Pencil icon for the Notes.

Copy the new address of your customer from the Notes.

Paste it in the Bill To or Ship To field.

Let me know how it works for you. Have a good one.
