Business and personal account question

Hi, I have Ring doorbell and to store the recordings in cloud, I have subscribed to the Ring $30 per year plan. It is paid for by my personal credit card. I have created a Ring account for my wife (say abc@gmail.com) and given her full access to doorbell. It is working out great. Now, my wife wants to install an indoor camera at her salon overlooking the parking lot using the same account (abc@gmail.com). She wants the recordings to be stored in cloud but paid for by her business credit card since it is a business related expense. She also wants to give me full access to the camera. Is it possible to add a $30/year plan to her Ring account (abc@gmail.com)? Then add the camera to her account and then give me full access to camera? Would this in any way, disturb the current setup with doorbell? Thanks, Arun
