Who needs to generate e-invoices under GST in India?

All businesses with aggregate annual turnover of ₹5 crore and above must generate e-invoices under GST. The threshold has been progressively lowered by CBIC. Check the latest GSTN notification for current limits.

Which IRP portals does ROSTAN support for e-invoicing?

ROSTAN supports all 4 government-approved IRP portals: NIC IRP (e-invoice1.nic.in), IRIS IRP, ClearTax IRP, and Masters India IRP. You can switch between portals without any changes to your ERP.

How long does IRN generation take with ROSTAN?

IRN is generated in under 3 seconds under normal load. ROSTAN's system processes 1 lakh+ invoices per day with 99.9% uptime SLA and real-time monitoring dashboard.

Can ROSTAN integrate GST e-invoicing with Oracle EBS?

Yes. ROSTAN has pre-built Oracle EBS connectors that integrate with the AR Invoice module. The connector sends invoice data to ROSTAN's API and writes back the IRN, QR code, and e-way bill number to EBS automatically — without any manual steps.

Is e-way bill generation included in ROSTAN's e-invoicing solution?

Yes. E-way bill can be generated in the same API call as IRN generation, or separately. All required fields are auto-populated from your ERP invoice data. This eliminates the need for a separate e-way bill integration.

What happens if the IRP portal is down?

ROSTAN's system has a failover queue — invoices are held and auto-retried when the portal recovers. Businesses can issue invoices with a time-stamp exception during genuine IRP downtime as per GSTN guidelines.

Does ROSTAN support bulk IRN generation for high-volume businesses?

Yes. ROSTAN's e-invoicing platform handles 1 lakh+ (100,000+) invoices per day. Bulk IRN generation is supported via REST API with concurrent processing, making it suitable for manufacturing, retail, and logistics businesses with high invoice volumes.

What is the cost of ROSTAN's GST e-invoicing software?

Pricing is based on your invoice volume, ERP system, and number of GSTINs. ROSTAN provides a tailored quote after a free assessment. Contact our team at info@rostantechnologies.com or call us for a customised pricing proposal.
