Hi @ValerieMay ,
Thank you for getting in touch. Shopify Payments is a payment gateway you can use to accept payments from customers. You can link your bank account to Shopify Payments and you will receive payouts from your orders within a few days.
You can disable Shopify Payments at any time, but you’ll need to use an alternative gateway if you still want to accept payments from customers for their orders. Can you tell me more about why you might want to make a change?
