The PCA is the main account holder and controls everything within the Single Serve Merch account associated with your organization. All user roles and permissions for all stores are managed from this account. Once store admins are established, they manage the individual store users.
A few steps to consider during initial set-up:
Complete your company account information along with your logo
Add your Stripe account [Admin Stripe Account] to the PCA which will be added as the default Stripe account.
Company Users -individuals from your organization who will be supporting this endeavor either designing, adding products, or managing the stores. Permissions are defined under a few different roles.
Note: An additional PCA can be added which offer two users with full control over the account.
