Saudi VAT Pro — ZATCA Phase 2 E-Invoicing

saudivat.pro automates ZATCA Phase 2 e-invoicing for Saudi Arabian businesses — WooCommerce stores, Shopify merchants, and custom integrations via REST API.

Every paid order becomes a ZATCA-compliant invoice. Every refund becomes a credit note. No developers required.

The Platform

→ Sign up free at saudivat.pro

Saudi VAT Pro handles the complexity of ZATCA Phase 2 compliance so you don't have to:

• CSID onboarding — generate your Cryptographic Stamp Identifier in 5 minutes with the free CSID wizard
• B2B clearance — standard invoices cleared with ZATCA in real time before delivery
• B2C reporting — simplified invoices reported within 24 hours
• Credit notes — refunds automatically generate ZATCA-compliant credit notes
• Issue dashboard — plain-language explanations of every ZATCA rejection, with suggested fixes
• Retry & repair — re-submit failed invoices without touching code

Supported platforms

AI Agents & Model Context Protocol

The Saudi VAT Pro MCP server lets MCP-compatible AI assistants create and manage ZATCA invoices through the Saudi VAT Pro API.

{
  "mcpServers": {
    "saudi-vat-pro": {
      "command": "npx",
      "args": ["saudi-vat-pro-mcp"],
      "env": {
        "SAUDI_VAT_PRO_API_KEY": "svp_live_YOUR_KEY_HERE"
      }
    }
  }
}

Available tools cover invoice listing and details, standard and simplified invoice creation, idempotent credit notes, failed-invoice retries and explanations, merchant details, dashboard summaries, and ZATCA certificate readiness.

The server gives agents explicit ZATCA safeguards:

• Standard B2B invoices require buyer name, city, and a valid 15-digit VAT number
• VAT categories, rates, VATEX exemption reasons, and line discounts are validated before submission
• Sandbox and production environments are clearly distinguished
• Credit-note retries require an idempotency key to prevent duplicate refunds
• Every result exposes its actual lifecycle status instead of assuming clearance or reporting succeeded

import { encodeTlvPhaseOne, decodeTlv, validateQr } from './zatca-qr-helpers/index.js';

// Generate a Phase 1 QR code
const base64 = encodeTlvPhaseOne({
  sellerName: 'Riyadh Gadgets Trading Co.',
  vatNumber:  '310000000000006',
  timestamp:  '2024-01-15T10:30:00Z',
  invoiceTotal: '1725.00',
  vatAmount:    '225.00',
});

// Decode any QR string
const parsed = decodeTlv(base64);
parsed.fields.forEach(f => console.log(f.tag, f.label, f.rawValue));

// Validate
const { valid, errors } = validateQr(base64);
