Billing Vat Validator

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its badge, button, input, label dependencies and any missing npm packages, and installs them straight into your project.

Prefer not to use the CLI? Copy the source from the Code toggle above into src/components/blocks/billing/billing147.tsx instead.

Usage

The file also exports billing147Demo, the exact props behind the preview above. Spread it to get a working section in one line, then replace it with your own data.

import { Billing147, billing147Demo } from "@/components/blocks/billing/billing147";

export default function Page() {
  return <Billing147 {...billing147Demo} />;
}

Props

Types

interface VatCountryOption {
  code: string;
  name: string;
}

Behavior notes

• Validation only runs when the Validate button is clicked, not on every keystroke; typing in the input or switching country resets the result back to idle.
• Format checking uses a small built-in COUNTRY_DIGIT_PATTERNS map for DE, FR, IE, NL, ES, and IT; any other country code falls back to a generic 5-12 character alphanumeric pattern.
• A failed format check shows 'Not a valid format' immediately. A passing format check shows a brief 'Checking with VIES...' state for 900ms before flipping to valid, simulating a remote lookup with no real network call.
• The reverse-charge note only appears once state is 'valid' and the selected country differs from baseCountryCode.
• Country selection uses a chip-style radiogroup instead of a native select, since the UI kit has no Select primitive.
