Checkout options: tips, terms and customer details

In Business → Store Configuration:

• Checkout Contact Method — whether customers must give an email, a phone number, either, or just their name.
• Enable Tips — let customers add a tip.
• Terms and Conditions — require customers to accept your terms.
• Collect Marketing Preferences — show email/SMS sign-up options on your storefront.

Choose contact requirements that match how you actually communicate. An order without a usable email cannot receive an email notification; having a phone number does not by itself enable customer SMS or marketing consent.

Save and walk through checkout as a customer to review the fields, terms and tip choices. Turning on Collect Marketing Preferences offers sign-up choices; it does not automatically opt every customer into campaigns.
