Published: June 23, 2026 · Author: Artha365

Introduction to GSTR-2B Reconciliation

Reconciling GSTR-2B with your purchase register is a critical step in ensuring you claim the correct Input Tax Credit (ITC) without facing notices from the GST department. Artha365’s GSTFlow Engine automates this process locally on your machine, ensuring complete data privacy.

Step 1: Download GSTR-2B JSON

First, log in to the GST Portal and navigate to Services > Returns > Returns Dashboard. Select the financial year and return period, then click on the ‘Download’ button under GSTR-2B to get the JSON file.

Step 2: Import your Purchase Register

Open Artha365 and go to the GSTFlow module. Click on ‘Import Purchase Register’. You can upload your data using our standard Excel template or connect directly to Tally/Zoho if you have configured the integration.

Pro Tip: Ensure that your supplier GSTINs in your purchase register exactly match the GSTINs in the GSTR-2B file to avoid mismatch errors.

Step 3: Run the Reconciliation Engine

Upload the downloaded GSTR-2B JSON file into Artha365. Click ‘Run Reconciliation’. The engine will instantly compare the records and categorize them into:

Matched: Perfect match between your books and portal.
Mismatch: Differences in invoice value, tax amount, or date.
Missing in Portal: Invoices in your books but not uploaded by the supplier.
Missing in Books: Invoices on the portal but not accounted for in your books.

Step 4: Take Action

You can directly email suppliers with missing or mismatched invoices using the automated communication feature in Artha365.
