You can move onto our Paused plan, which is offered at a reduced rate of $14/month. This plan disables your checkout so that you're not able to make sales, however allows you maintain a live website and continue to access your admin when you want to. You can stay on this plan for any amount of time that you like.
The other option would be to fully cancel your store, in which case you would not pay any monthly fee but would not have access to your admin at all. In this case, your store's information would be stored for up to 90 days - as long as you reactivate your store within that timeframe, all of your data would be there waiting for you.
