Sophia here from Shopify. Welcome to the Shopify Community!
I'd be happy to take a look at your shipping and payment settings. Is there anything in particular you're concerned about? If you'd like the Community to review the checkout process and the shipping options available to customers, please share your store URL here so that everyone can have a look. It'd be great to know which country the business is operating from and which payment provider(s) you have enabled as well.
Looking forward to chatting with you!
