Help
Context-sensitive help is available — inline help text near complex inputs, help links, or a chat-launch path.
What it requires
WCAG 2.0 SC 3.3.5 (AAA) requires that complex form steps offer help. A tax-ID input might need explanatory text ("Your VAT number from your invoice"); a phone-number field might need format guidance.
Implementation: inline `<small>` help text, an `aria-describedby` link to a help paragraph, or a "?" icon that opens a tooltip.
Common Shopify failure
Custom B2B order form asking for "Tax ID" with no format guidance. Address form requesting "ZIP/postcode" without locale-specific formatting hints.
How to fix it
AccessComply's form-fix agent attaches inline help text via `aria-describedby` for fields whose names match a known-complex pattern (tax-id, vat, ein, ssn, etc).
