Question 1

What is a GST e-Invoice and how is it different from a regular invoice?

Accepted Answer

A GST e-Invoice is a tax invoice that has been registered with the government's Invoice Registration Portal (IRP), after which it receives a unique IRN (Invoice Reference Number) and a digitally signed QR code. Unlike a regular invoice that exists only in your system, an e-Invoice is validated and authenticated by the government in real time, making it the authoritative record for B2B transactions and ITC claims.

Question 2

Who is required to generate e-Invoices under GST?

Accepted Answer

e-Invoicing is currently mandatory for all GST-registered businesses whose aggregate annual turnover exceeds ₹5 crore in any preceding financial year. This applies to Tax Invoices, Credit Notes, and Debit Notes issued for B2B, B2G, export, and SEZ supplies. Businesses below the threshold are not required to generate e-Invoices but can opt in voluntarily.

Question 3

How does LEDGERS generate e-Invoices - what is the exact process?

Accepted Answer

When you create a B2B tax invoice in LEDGERS, the system validates all mandatory fields against the GSTN schema - including GSTIN, HSN codes, tax amounts, and place of supply. Once validated, LEDGERS submits the invoice data directly to the IRP via a secure API connection. The IRP returns the IRN and digitally signed QR code, which LEDGERS automatically embeds on the invoice PDF. The entire process completes in seconds with no manual portal login.

Question 4

What is an IRN and why does every e-Invoice require one?

Accepted Answer

An IRN (Invoice Reference Number) is a unique 64-character alphanumeric hash generated by the IRP for each registered e-Invoice. It is computed from the supplier's GSTIN, financial year, and invoice number - ensuring it is globally unique within the GST system. Without a valid IRN, an invoice is not considered a legally compliant e-Invoice, and the buyer cannot claim Input Tax Credit (ITC) on it.

Question 5

What happens if the IRP rejects my e-Invoice submission?

Accepted Answer

IRP rejection usually occurs due to schema validation errors - such as an inactive or incorrect GSTIN, missing HSN codes, tax amount mismatches, or incorrect place of supply. LEDGERS pre-validates all invoice data before submission to catch these errors early. If the IRP still rejects, LEDGERS displays the exact rejection code and field causing the error, lets you correct it instantly, and resubmit without losing any data.

Question 6

Can I cancel an e-Invoice after it has been registered with the IRP?

Accepted Answer

Yes, but only within 24 hours of the original registration time. During this window, you can cancel the e-Invoice directly from LEDGERS with a single click, and the cancellation is communicated to the IRP. After 24 hours, the IRN cannot be cancelled - you must issue a Credit Note instead to reverse or adjust the transaction. LEDGERS handles both flows and links the Credit Note to the original e-Invoice automatically.

Question 7

Does LEDGERS support bulk e-Invoice generation?

Accepted Answer

Yes. LEDGERS supports bulk e-Invoice generation via Excel template upload and through API integration for ERP-connected businesses. You can upload hundreds of invoice records, validate them against the GSTN schema in one pass, and register all compliant invoices with the IRP in a single batch. Failed records are listed separately with correction hints, so you can fix and resubmit without affecting the rest of the batch.

Question 8

Can I generate e-Invoices from my mobile device?

Accepted Answer

Yes. LEDGERS is fully accessible on mobile browsers and the LEDGERS mobile app (Android and iOS). You can create a B2B invoice, trigger IRP registration, and share the IRN-stamped invoice with your customer - all from your phone. This is especially useful for field teams or businesses that invoice at the point of delivery.

Question 9

Can I generate an e-Way Bill along with the e-Invoice?

Accepted Answer

Yes. LEDGERS allows you to simultaneously generate an e-Way Bill alongside the e-Invoice whenever the consignment value exceeds ₹50,000 and the goods are being transported. Both the e-Invoice and e-Way Bill share the same invoice data, so there is no duplication of entry. They are linked by the IRN and can be tracked together from a single unified workflow in LEDGERS.

Question 10

How quickly can I activate e-Invoicing on LEDGERS?

Accepted Answer

Activation takes under five minutes. Go to Settings in LEDGERS, navigate to e-Invoice configuration, verify your GSTIN eligibility, and enable e-Invoicing for your organization. LEDGERS connects to the IRP sandbox for testing before going live. Once activated, every new B2B invoice you create will automatically go through the IRP registration flow - no additional steps needed.
