Trusted Digital Transformation Partner
GST e-invoicing in India requires invoices above the applicable turnover threshold to be reported to an Invoice Registration Portal (IRP), which returns an Invoice Reference Number (IRN) and a signed QR code before the invoice is legally valid. In practice the hard part is not the portal — it is the ERP. Most failures we see are master-data problems surfacing as portal rejections: a missing or wrong HSN code, a tax setup that does not match the transaction, or a payload the IRP will not accept. ROSTAN integrates IRN and e-way bill generation directly into Oracle EBS and Fusion Receivables, so compliance is produced from the same invoice the business already raises.
Mandatory for Businesses with
₹5 Crore+ Annual Turnover
GST E-Invoicing (Electronic Invoicing) under India's GSTN system requires businesses to generate a unique Invoice Reference Number (IRN) from a government-approved IRP portal before sending invoices to customers.
ROSTAN's solution automates the entire workflow — from ERP invoice creation to IRN generation, QR code embedding, e-way bill creation, and audit reporting — all in under 3 seconds.
