1. Instant Field Checks

Instant field checks catch errors as they happen. They speed up checkout and cut frustration.

How to improve your store:

  1. Address Autocompletion: Use Google Autocomplete. Cuts input time by 20% and lowers mobile errors.
  2. Credit Card Validation: Check card numbers upfront. Prevents later headaches.
  3. Email Verification: Check emails as they’re entered. Block disposable domains to stop fake orders.
  4. Phone Number Formatting: Verify against country codes. Prompt if digit count is off.

Shopify Functions let you create custom rules:

Rule Action
Cart total > $1,000 Warn new customers
Item quantity over limit Block order

Use JavaScript or Rust (faster) to implement these checks.

Remember: Always back up front-end checks with server-side validation for sensitive data.

2. Clear Error Messages

Clear error messages guide customers through checkout issues. They cut frustration and improve shopping.

How to craft effective messages:

  1. Be specific: Say exactly what’s wrong.
  2. Offer solutions: Tell users how to fix it.
  3. Use simple language: Skip the jargon.
  4. Stay positive: Frame messages constructively.
  5. Add visual cues: Use colors and icons to highlight errors.

Real-world examples:

Poor Message Better Message
"Nope" "Username taken. Choose another."
"Error 404" "Page not found. It may have moved or been deleted."
"Invalid input" "Enter phone as (XXX) XXX-XXXX"

Dropbox nails it: "Include an ‘@’ in the email. ‘username’ is missing an ‘@’."

MailChimp saves time: They tell you if a username doesn’t exist before you try to log in.

3. Address Checking

Address checking ensures correct shipping details. It’s crucial for deliveries and happy customers.

Why it matters:

  • Fewer failed deliveries
  • Lower shipping costs
  • Better customer experience

How to do it:

  1. Real-time validation: Use an Address Verification System (AVS).
  2. Offer suggestions: Provide options for incomplete addresses.
  3. Check against postal databases: Cross-reference with official records.
  4. Allow manual override: Let customers use their address if needed.
  5. Flag PO boxes: If you don’t ship to them, catch them early.

Real-world examples:

Oatly! Address Validator app 98% fewer manual checks

EasyPost claims to boost deliverability by up to 82%.

4. Phone Number Formatting

Phone formatting ensures correct contact info. It’s key for order processing and communication.

How to do it:

  1. Use regex: Validate for numbers only.
  2. Strip non-numbers: Remove everything but digits and ‘+’.
  3. Set limits: Max 20 characters for phone numbers.
  4. Standardize: Consider E.164 format for international numbers.
  5. Real-time checks: Validate as users type or move fields.

Company examples:

"Looks like there’s a number missing from the phone." – Greta, Shopify
