# Overview

> Learn how to automate GSTR-2A reconciliation with purchase ledgers using the GST Analytics API.

## What is GSTR-2A

GSTR-2A is a dynamic tax return form that auto-populates based on the e-Invoices generated by suppliers as well as the data reported by them on an ongoing basis. It reflects the inward supplies (purchases) of a GST-registered business, providing details on all purchases made from registered suppliers within a particular period. Unlike GSTR-2B, GSTR-2A is constantly updated as and when suppliers upload their returns, making it a real-time reflection of the purchases.

## What is GSTR-2A Reconciliation?

GSTR-2A Reconciliation refers to the process of matching a business's internal purchase records with the data available in the GSTR-2A form. The purpose of this process is to identify any mismatches or discrepancies between the business's reported purchases and the data uploaded by suppliers.

### Why GSTR-2A Reconciliation is important?

Since GSTR-2A provides real-time visibility into purchases, especially through e-Invoices, businesses can track and verify transactions as soon as the suppliers generate e-Invoices. This allows them to validate and correct any discrepancies before the official GSTR-1 filings, making GSTR-2A a critical tool for continuous monitoring.
