If you need to disconnect your Stripe account from your SiteSwan account, you can easily do that by following these steps...
Step 1 - From your dashboard, click on "Account"
Step 2 - Click on "Disconnect from Stripe" from the "Collect Online Payments" window.
Step 3- Click "OK" to confirm that you want to disconnect from Stripe.
A "Disconnect successful message will appear" which means you can now connect a new Stripe account if you need to...
Note: If the "Disconnect from Stripe" button is grayed-out that means that you have active or past due clients in your account. You would need to first cancel any active or past due Client Billing subscriptions for all websites in your account before disconnecting from Stripe.
