What appears on your customer bank statement would depend on the payment provider you use. For example, if you use Shopify Payments, then you’ll have the option to set up the statement description so it shows your business name. Every Shopify charge will appear as SP * YOURSTORENAME - You can manage this by going to Settings/Payment Providers/Manage. If you are using a third-party payment provider then you will want to reach out to them directly as they will be able to provide an answer on what appears on your customers bank statement.
