The Problem

Why is GSTR-2B reconciliation so frustrating?

GSTR-2B is the auto-drafted ITC statement the GST portal generates from supplier filings. Matching it against your purchase register by hand is slow, error-prone, and gets harder with every new GSTIN you take on.

Mismatches hide in plain sight

GSTIN typos, invoice number variations, and rounding differences slip past manual checks until a notice arrives. Spotting them by eye across thousands of line items is nearly impossible.

3-5 days, every single month

Firms managing dozens of GSTINs lose entire staff-weeks to line-by-line spreadsheet matching, every single filing cycle, without fail.

ITC denied after the fact

Vendors who short-file or stop filing put your client's Input Tax Credit at risk and manual checks rarely catch it before the return is already filed.

Every new GSTIN multiplies the chaos

Firms managing multiple GSTINs and clients end up juggling a fresh spreadsheet for every entity, every period, with no single view of overall risk.

No early warning on vendor risk

You only find out a vendor has a poor compliance history after ITC has already been reversed, when it's too late to follow up or adjust.

Notices arrive without context

Mismatches surface as GST department notices months after filing, forcing a scramble to reconstruct reconciliation that should have happened upfront.

GSTR-2B AI fixes all 6 of these - automatically.

Frequently Asked Questions

Common questions about GST reconciliation.

  1. GSTR-2B AI is a GST reconciliation platform built by Fullestop that lets CA firms and finance teams auto-match purchase registers against GSTR-2B, flag ITC risk, and manage unlimited GSTINs. It reduces manual spreadsheet work and helps you catch mismatches before they turn into notices all from a simple dashboard.

  2. Yes, a Free plan is available with no credit card required 1 GSTIN, up to 500 invoices a month, and core mismatch detection. Paid plans unlock unlimited GSTINs, ITC risk scoring, and vendor follow-ups, with a 7-day free trial on every paid tier.

  3. GSTR-2B is a static, auto-drafted ITC statement generated by the GST portal from your suppliers' GSTR-1 filings. Reconciling it against your purchase register ensures you claim only eligible ITC and avoid notices or audits.

  4. GSTR-2B AI compares every invoice in your purchase register against the GSTR-2B statement GSTIN, invoice number, taxable value, and tax amount. It handles common data entry variations and rounding differences, reaching 99.8% matching accuracy versus the typical 85 90% from manual checks.

  5. ITC risk identification scores every vendor on filing behaviour short-filing, non-filing, and past reversals to flag Input Tax Credit at risk before you submit GSTR-3B. Without it, these risks are usually only discovered after the credit has already been reversed.

  6. Yes. GSTR-2B AI can reconcile multiple tax periods and multiple GSTINs at once. You can review every mismatch before exporting reports, which saves hours of manual line-by-line checking every filing cycle.

  7. Yes. GSTR-2B AI accepts Excel/CSV purchase registers, Tally and major ERP exports, and the official GSTR-2B JSON from the GST portal. There's nothing to install in your existing accounting system.

  8. GSTR-2B AI offers a Free plan plus Starter, Professional, and Enterprise paid tiers. Whether you're a solo consultant or a CA firm managing hundreds of GSTINs, there's a plan that scales with your client volume.

  9. GSTR-2B AI combines three things most tools don't: AI-driven ITC risk scoring with vendor compliance trends, automated vendor follow-ups built into the dashboard, and a genuinely unlimited multi-GSTIN workspace all in one platform at 99.8% matching accuracy.

  10. Yes. GSTR-2B AI imports the GSTR-2B JSON directly so you don't have to download and re-upload files by hand, and refreshes reconciliation as soon as the portal updates the statement on the 14th of each month.

  11. Every vendor gets a score built from filing consistency, the invoice match rate against GSTR-2B, and any history of short-filing or ITC reversal. The score updates automatically every reconciliation cycle no manual tracking needed.

  12. Reconciling GSTR-2B requires six core checks: validating every GSTIN, matching invoice numbers and amounts, flagging rounding differences, scoring vendor filing risk, following up on pending invoices, and exporting an audit-ready report before GSTR-3B. GSTR-2B AI handles all six automatically from a single dashboard.

  13. GSTR-2B AI's Free plan is one of the most complete free GST reconciliation tools available in 2026 unlike tools that gate mismatch detection behind a paywall, it includes GSTIN validation, basic reconciliation reports, and GSTR-2B JSON import at no cost, no credit card required.

  14. GST reconciliation follows the same matching logic as general bookkeeping comparing two records for accuracy but it has GST-specific challenges: GSTIN validity, vendor filing status, ITC eligibility rules, and monthly statement refreshes. GSTR-2B AI is built specifically for these constraints, not adapted from a generic accounting tool.
