MANUAL COMPLIANCE RISKS

Manual e-Invoicing Is Costing You More Than Time

Traditional portal uploads slow down dispatch, increase rejection rates, and expose your enterprise to compliance notices.

Manual Uploads Waste Hours

Manual login to government portals and re-keying invoice data eats hours every week and leads to costly data-entry mistakes.

IRP Rejections & Mismatched Data

A single incorrect HSN code, mismatched GSTIN, or Place of Supply error triggers immediate portal rejection and payment delays.

30-Day Reporting Rule Risk

For businesses with AATO ≥ ₹10 Cr, missing the 30-day reporting window means the document can never receive a valid IRN.

Disconnected Billing & Accounting

Managing e-invoices in a separate utility forces painful double data entry and reconciliation nightmares during GSTR-1 filing.

The T7 ERP Promise

One platform that prepares, validates, submits to IRP, and auto-embeds IRN & QR in under 5 seconds.

GST REGULATORY GUIDE

Understanding GST E-Invoicing Rules & Thresholds in India

Essential compliance guidelines issued by CBIC and GSTN for Indian taxpayers.

Turnover Threshold

Mandatory for GST-registered businesses whose aggregate annual turnover (AATO) exceeds ₹5 crore in any preceding financial year (effective 1 August 2023).

Covered Transactions

Applies to B2B sales invoices, export invoices, debit notes, and credit notes. B2C invoices are currently excluded from mandatory IRP IRN generation.

30-Day Reporting Window

Businesses with AATO ≥ ₹10 crore must report invoices to the IRP within 30 days of invoice date; older documents are rejected for IRN generation.

24-Hour Cancellation Limit

An e-invoice can only be cancelled on the IRP within 24 hours of generation. Post 24 hours, modifications must occur via a credit or debit note.

Mandatory IRN & QR Code

Every valid e-invoice must carry a unique 64-character IRN and a digitally signed QR code. Without these, the document is legally invalid under GST law.

e-Way Bill Linkage

When moving goods above ₹50,000, Part A and Part B of the e-Way Bill can be pre-filled and generated simultaneously alongside the e-invoice.

FREQUENTLY ASKED QUESTIONS

Questions About GST E-Invoicing Software

Everything you need to know about IRN generation, rules, and T7 ERP features.

An e-invoice (electronic invoice) is a standard B2B sales document whose data is submitted to an Invoice Registration Portal (IRP) for authentication under GST law. Once verified, the IRP returns a 64-character Invoice Reference Number (IRN) and a digitally signed QR code. Under GST regulations, invoices without a valid IRN and QR code are not considered legally valid B2B tax invoices.
E-invoicing is mandatory for GST-registered taxpayers whose Aggregate Annual Turnover (AATO) in any preceding financial year exceeds the government-notified threshold (currently ₹5 crore, effective 1 August 2023). It applies to B2B sales invoices, export invoices, debit notes, and credit notes.
In T7 ERP, you create your sales invoice as usual. Upon clicking 'Generate E-Invoice', T7 ERP validates your invoice data locally, converts it to the government-prescribed JSON format, and transmits it via secure API to the IRP. The returned IRN and digitally signed QR code are automatically attached to your invoice print copy.
An IRN (Invoice Reference Number) is a unique 64-character alphanumeric hash generated by the IRP using a SHA-256 algorithm based on the supplier GSTIN, financial year, document type, and invoice number.
The digitally signed QR code contains key invoice attributes: GSTIN of supplier and recipient, invoice number, invoice date, total invoice value, number of line items, HSN code of the main item, unique IRN, and digital signature of the IRP.
Yes. T7 ERP includes a dedicated bulk generation mode. You can select hundreds of eligible sales invoices from your register and submit them in a single batch. T7 ERP processes each invoice independently, displaying a real-time success/failure report.
Yes. An e-invoice can be cancelled on the IRP within 24 hours of IRN generation, provided no linked e-Way Bill is active. After 24 hours, the IRP blocks cancellation, and any correction must be executed by issuing a credit or debit note in T7 ERP.
Taxpayers with an AATO of ₹10 crore or more must report their B2B invoices, credit notes, and debit notes to the IRP within 30 days of the invoice date. Documents older than 30 days are rejected by the IRP.
Yes. T7 ERP provides a unified workflow. When generating an e-invoice for goods movement exceeding ₹50,000, you can supply vehicle/transporter details to generate both the e-invoice and linked e-Way Bill simultaneously.
T7 ERP features auto-queue and retry logic. If the IRP portal is unreachable due to maintenance or downtime, T7 ERP queues the invoice locally and automatically retries at intervals, notifying your team once the IRN is received.
T7 ERP performs pre-submission validation before sending data to the IRP. If a field fails validation (e.g., invalid GSTIN format or missing Place of Supply), T7 ERP highlights the error inline in plain language so you can fix it before calling the API.
Yes. T7 ERP allows you to configure multiple GSTINs and business locations under one master company profile, enabling branch-wise e-invoicing and consolidated multi-GSTIN reporting.
All data transmission between T7 ERP and the GST/GSP network uses TLS 1.2+ encryption. T7 ERP enforces role-based access control, encrypted data storage, and complete statutory audit logging.
Yes. You can schedule a free walkthrough demo with our compliance team using your own sample invoices, HSN codes, and GSTIN parameters.
