Trusted Digital Transformation Partner
Multi-Country E-Invoicing Platform
Tax administrations worldwide are rapidly mandating e-invoicing — requiring businesses to submit structured, digitally-signed invoices to government portals in real time, before a transaction is recognized. ROSTAN's Global E-Invoicing Solution is a cloud-based, API-first platform that makes your business compliant across India (GST/IRP), UAE (FTA), Saudi Arabia (ZATCA/Fatoorah), Malaysia (MyInvois/LHDN), and the EU (Peppol/EN16931) from a single integration point.
Unlike point solutions that cover only one jurisdiction, ROSTAN's multi-country routing engine applies the correct tax schema, digital signature, clearance model, and submission protocol for each country automatically. Your ERP team integrates once; compliance across every market is handled behind the scenes — with real-time dashboards, IRN/QR code write-back, and audit-ready storage included.

End-to-End Workflow — From ERP to Tax Authority
ROSTAN's intelligent workflow engine ingests invoice data from any source system, validates it against jurisdiction-specific schemas, routes it to the correct national tax authority portal, obtains the IRN and digital signature, then writes the compliant invoice back to your ERP — all in under 3 seconds per invoice. The same pipeline supports India's IRP/GSTN, Saudi Arabia's ZATCA clearance model, UAE's FTA, Malaysia's MyInvois, and European Peppol — without changing your ERP setup.
Frequently Asked Questions
Which businesses are mandated to use e-invoicing under GST in India?
As of 2024, e-invoicing is mandatory for all B2B taxpayers with annual aggregate turnover of Rs. 5 crore or more. The mandate rolled out progressively: Rs. 500 Cr+ (Oct 2020), Rs. 100 Cr+ (Jan 2021), Rs. 50 Cr+ (Apr 2021), Rs. 20 Cr+ (Apr 2022), Rs. 10 Cr+ (Oct 2022), Rs. 5 Cr+ (Aug 2023). Further expansion to smaller taxpayers is expected. Exporters and SEZ units are also covered. B2C, banking, insurance, and passenger transport entities are currently exempt.
Which countries and e-invoicing mandates does ROSTAN support?
ROSTAN supports five major jurisdictions:
- India: GST e-invoicing via GSTN IRP - IRN, QR code, e-way bill
- Saudi Arabia: ZATCA Fatoorah Phase 1 & 2 - clearance model, UBL XML, cryptographic stamp
- UAE: FTA VAT e-invoicing - PINT AE standard, XML UBL
- Malaysia: LHDN MyInvois - effective mid-2024 for large taxpayers
- Europe: Peppol EN16931 - applicable across 34 countries
Additional coverage (Turkey, Egypt, Vietnam, Indonesia) is on the 2025 roadmap.
How long does implementation take and what is required from our IT team?
For standard ERPs (SAP, Oracle, Tally), implementation takes 2-4 weeks using pre-built connectors - no custom development required. For custom ERP systems via REST API, your team sends a JSON payload; ROSTAN returns the IRN, signed XML, and QR code. API documentation with Postman collections and sandbox credentials is provided from Day 1. Typical IT effort is 3-5 developer days. ROSTAN assigns a dedicated implementation engineer throughout onboarding.
What happens if the IRP or government portal is down?
ROSTAN maintains simultaneous connections to multiple GSPs and all active IRPs in failover mode. If one portal is unavailable, requests are automatically re-routed with no action from your team. During total downtime (e.g., maintenance windows), ROSTAN queues invoices and submits them automatically on restoration. The platform maintains a 99.9% uptime SLA with real-time alerts via webhook, email, and SMS.
How is invoice data security and confidentiality handled?
Enterprise-grade security at every layer:
- In transit: TLS 1.3 encryption; mTLS for ERP-to-ROSTAN communication
- At rest: AES-256 encryption for all stored invoice data
- Access control: Role-based access (RBAC), MFA for admin accounts, full audit log
- Infrastructure: ISO 27001-aligned cloud; SOC 2 Type II audit in progress
- Data residency: India-region data stored on Indian data centers per DPDP Act 2023
Can ROSTAN handle high invoice volumes and seasonal peaks?
Yes. The platform handles 1 lakh+ invoices per day per client with auto-scaling for month-end and festive season bursts. Key features: horizontal auto-scaling, bulk processing API (500+ invoices/call), dedicated per-client queues, and real-time throughput dashboards. Enterprise clients above 5 lakh invoices/month receive a dedicated infrastructure cluster with guaranteed processing SLAs.
