TallyPrime GSTR-2B & 2A Integration - Auto ITC Reconciliation
The TallyPrime GSTR-2B / 2A reconciliation connector fetches monthly GSTR-2B and 2A statements from the GST portal and matches every vendor invoice against your TallyPrime purchase register. Missing invoices, wrong GSTINs, and rate mismatches are flagged with drill-down to the offending voucher — the manual ITC reconciliation exercise every Indian finance team runs 3-5 days per month collapses into an overnight batch. Zero manual data entry between the ERP and the connected app.
Auto-reconcile GSTR-2B and 2A vendor invoices with TallyPrime purchase register — catch missing ITC, wrong GSTINs, and rate mismatches before filing.
Month-end reconciliation time saved per GSTIN
Invoice-level match accuracy after tolerance tuning
Portal polling frequency during filing window
ITC leakage prevention with pre-filing mismatch flagging
What this connector does
GSTR-2B and 2A input tax credit reconciliation is the highest-friction monthly compliance activity for every Indian business that claims ITC. The manual workflow — download the JSON, open in Excel, match line-by-line against the Tally purchase register, chase every mismatch — consumes 3 to 5 full days per GSTIN per month, and it happens under the pressure of the 20th-of-month GSTR-3B deadline. This connector automates the entire cycle end-to-end. GSTR-2B is fetched from the GST portal via the Connected GST API path the moment it publishes for a return period. GSTR-2A is polled every 6 hours during the filing window because 2A is dynamic — new supplier filings keep landing until the 11th. Every fetched invoice is matched against the Tally purchase register using invoice number, GSTIN, and amount, with configurable tolerance for split invoices and partial supplies. Mismatches are categorised (missing on portal / missing in books / rate diff / GSTIN diff / cancelled supplier) with a drill-down link to the offending voucher.
The vendor follow-up cycle is one of the most painful parts of ITC reconciliation, and this connector makes it painless. When an invoice is missing from GSTR-2B but present in Tally, the vendor is auto-queued for a WhatsApp follow-up using pre-approved DLT templates. When a supplier GSTIN gets cancelled between invoice date and reconciliation, the connector flags the ITC reversal need with the exact voucher list. Cancelled buyer GSTINs — the classic ITC-reversal trap — are caught pre-filing, not after the tax notice arrives.
Multi-GSTIN group setups are directly supported. Each GSTIN has its own mismatch queue, its own dashboard, and its own audit trail — statutory boundaries stay clean — but the finance controller has one consolidated view across every group entity. Runs in India region end-to-end, with GST portal and inference calls staying inside ap-south-1 for DPDP Act 2023 alignment.

Built for teams that need reliable automation
The TallyPrime <-> GSTR-2B / 2A ITC Reconciliationconnector fits into finance, ops, and revenue teams that have outgrown copy-paste — the ones whose month-end close should not depend on a spreadsheet, whose ledger accuracy should not depend on human vigilance, and whose sales velocity should not stall behind an accountant's inbox.

Finance Controller
Owns monthly GSTR-3B filing and needs ITC reconciliation completed before the 15th of every month across every group GSTIN.
Chief Accountant
Handles the vendor follow-up cycle when supplier invoices are missing from GSTR-2B and needs WhatsApp reminder templates that work at scale.
CA Firm Partner
Manages multiple client Tallies and needs a single dashboard to run parallel reconciliations across every client GSTIN in the practice.

Frequently Asked Questions
Tally Connected GST handles GSTR-1 upload and GSTR-3B download natively. It does NOT reconcile GSTR-2B or 2A against your purchase register, which is where the real month-end pain lives. This connector layers that reconciliation on top of the Connected GST rail — it uses the same GSTN API path but adds the matching engine, categorisation logic, and vendor follow-up workflow that Tally does not ship.
The mismatch is queued with a "missing in books" label along with the vendor GSTIN, invoice number, and the amount. The accountant reviews and either approves it (creating the voucher in Tally in one click) or dismisses it as a genuine non-purchase entry. Every action is written to the audit log.
Yes. GSTR-2A is dynamic and updates through the month as suppliers file their GSTR-1. The connector polls every 6 hours during the filing window and re-runs the delta against your purchase register — so if a supplier files their GSTR-1 on the 12th, you see the update on your dashboard within hours, not at the end of the month.
Yes. Multi-GSTIN group setups are directly supported. Each GSTIN gets its own reconciliation queue, dashboard, and audit trail. Filings for group entities remain isolated for statutory purposes, but the finance controller has one aggregate view across all GSTINs.
