E-Invoicing under GST is mandatory for businesses with turnover above ₹5 crore (₹2 crore from FY 2026 onwards). Every B2B invoice must be uploaded to the Invoice Registration Portal (IRP) which generates an IRN (Invoice Reference Number) and QR code. FilingLab registers your business on the IRP, integrates with your billing software (Tally, Zoho, ERP), and trains your team.
Everything required for E-Invoicing Setup (IRP). Government statutory fees (MCA stamp duty, trademark filing fee, etc.) are charged at actual cost and shown separately before payment.
IRP portal registration
API integration with Tally / Zoho / SAP / ERP

Failure / cancellation handling
Keep these documents ready before starting. Our team will guide you through secure upload to our portal.
Pro Tip

E-invoicing meets the legal mandate for businesses above the ₹5 crore turnover limit, avoiding invalid invoices and ITC denial to buyers.
IRP-reported invoices flow automatically into GSTR-1 and the e-way bill system, cutting duplicate data entry and errors.
Each invoice gets a unique IRN and signed QR code from the IRP, making it legally valid and instantly verifiable.
We connect your billing or ERP software to the IRP via API so invoices register in real time at generation.
Authenticated e-invoices populate the buyer's GSTR-2B reliably, accelerating their input tax credit and strengthening B2B relationships.
