I need to bring my existing Laravel application in line with ZATCA Phase 2. The system already handles inventory, so your work must plug directly into that module while adding full e-invoicing capability. Key objectives • Generate invoices in the exact format ZATCA mandates, complete with QR code, hash, digital signature and any other Phase 2 fields. • Guarantee electronic invoicing compliance, including automatic clearance/reporting through the official APIs. • Integrate new logic with my current inventory management workflow so quantities, prices and item data flow into each invoice without breaking existing business rules. • Connect the app to any additional ZATCA services required for Phase 2, handling authentication, error responses and status tracking. Deliverables will be a merge-ready pull request with all new classes, migrations and tests, plus a concise setup guide so I can replicate the configuration in staging and production. If you have hands-on experience with Laravel, PHP-FPM, RESTful integrations and, ideally, previous work on Saudi e-invoicing, let’s talk details and timelines.
