Building New on 7.1 Trial Period

First time SquareSpace user. I'm building a new 7.1 site as my client has 7.0 and we want something totally new so we might as well go to 7.1. I have a design save and the trial expires in a few days. I'll be out of town and not have time to work on it until the following week. His 7.0 is paid through July. Will the design in progress automatically be saved to his account and allow me to work on it when I return? Or do we need to purchase it separately?

It can reside in the same account but it would need to be activated separately, however, you can request more time (and you will get it) by using the link in the expiration warning email that comes from Squarespace.
