Frequently Asked Questions

What is an IRN in a purchase invoice?

IRN stands for Invoice Reference Number. It is a unique 64-character hash generated by the Government's Invoice Registration Portal (IRP) for every electronic invoice under the GST system.

Why is reconciling IRN with GSTR-2A and GSTR-2B necessary?

Reconciliation ensures that the invoices in your internal purchase register match the data uploaded by your suppliers to the GST portal. This process is legally required to accurately claim Input Tax Credit (ITC) and prevent tax liabilities.

Can I automatically extract IRN data from a PDF invoice into a spreadsheet?

Yes, by using PDF editing software that includes OCR (Optical Character Recognition) technology, you can convert static images or scanned PDFs into editable text, allowing you to copy or export the IRN directly into spreadsheet cells.

What spreadsheet formulas are best for GST reconciliation?

VLOOKUP, XLOOKUP, and INDEX/MATCH are the most effective formulas for GST reconciliation. They allow you to search for specific invoice numbers or IRNs from your purchase register and find the corresponding match in your downloaded GSTR-2B data.
