Sidekick: Customize Checkout Form Fields

Help me customize the form fields on my Shopify checkout page:

Store name: [YOUR STORE NAME]
Business type: [PHYSICAL PRODUCTS / DIGITAL / SERVICES / SUBSCRIPTION]
Required custom info: [LIST ANY SPECIAL INFORMATION YOU NEED TO COLLECT]
Fields to remove: [LIST ANY UNNECESSARY DEFAULT FIELDS]

Customize the checkout fields as follows:


  
    Remove unnecessary fields - Hide or remove fields that are not needed for my business, such as [COMPANY NAME / APARTMENT LINE / PHONE NUMBER]. Walk me through which fields Shopify allows to be hidden versus which are required.
  
  Add custom fields - Add the following custom fields to the checkout:
    
      [CUSTOM FIELD 1 NAME] - Type: [TEXT / DROPDOWN / CHECKBOX] - Required: [YES/NO]
      [CUSTOM FIELD 2 NAME] - Type: [TEXT / DROPDOWN / CHECKBOX] - Required: [YES/NO]
Explain where in the checkout flow each field should appear.
    
  
  
    Field ordering - Rearrange fields so that email comes first (for abandoned cart recovery), followed by shipping address, then any custom fields. Place the phone number field last and mark it as optional.
  
  
    Smart defaults - Enable browser autofill compatibility for all standard address fields. Pre-fill the country field based on the customer IP geolocation.
  
  
    Conditional fields - Show certain fields only when relevant. For example, only show the company name field when a “Business purchase” checkbox is selected. Only show a delivery instructions field when a non-express shipping method is chosen.
  
  
    Validation rules - Add proper validation for phone numbers (format check), postal codes (country-specific format), and any custom fields. Show inline error messages directly below the invalid field.
  
  Field labels and placeholders - Use clear, conversational labels. Replace generic labels like “Address 1” with “Street address” and “Address 2” with “Apartment, suite, etc. (optional).”
