You can pause your store at a reduced rate of $14/month. Also known as the "dormant" plan, this disables your checkout so that you cannot receive orders, however allows you to maintain an active site and account so that you can login and work on your store during that time if you wish to do so.
Alternatively, you can fully close your store and then reactivate it later when you're ready (you will not be charged during this time). In this case, your data will be stored for 90 days so as long as you reactivate the store within that time frame, all of your store details will still be as you left them.
Instructions for both pausing and closing your store can be found here, Let me know if you have any questions!
