The Problem

Are you still doing GSTR-2B recon in Excel?

Every month, thousands of CAs waste hours on VLOOKUP-based reconciliation — error-prone, exhausting, and unscalable as client count grows.

  • 😤
    Manual VLOOKUP errors cost clients lakhsA single wrong cell match causes ITC overclaim — leading to notices, interest, and penalties
  • ⏳
    2–4 hours per GSTIN, every single monthMultiply that by 50 clients and you're losing 200+ hours a month to reconciliation alone
  • 🚨
    No clear ITC-at-risk visibilityIt's nearly impossible to quickly see how much ITC is at risk because vendors haven't filed GSTR-1 yet
  • 🔒
    Client data uploaded to unknown serversMost online tools require you to upload sensitive financial data — a serious privacy and confidentiality risk

FAQ

Questions & answers

Download GSTR-2B from the GST portal and export it as Excel (.xlsx or .xls). The tool supports the standard portal export format. After upload, you simply map which column corresponds to which field — the mapper auto-suggests based on your column headers.
Completely safe. All reconciliation logic runs in your browser using JavaScript — no data is ever transmitted to any server. Your client's invoice data, GSTIN, and amounts never leave your device. This makes it fully safe for professional CA use.
You can use any Excel format — the column mapper lets you tell the tool which column is Supplier GSTIN, Invoice Number, etc. We also provide a downloadable template you can share with clients for standardised input going forward.
Fuzzy matching normalises invoice numbers by removing slashes, dashes, spaces, and converting to uppercase before comparison. This means INV/25/001, INV-25-001, and INV25001 all match correctly — preventing false mismatches due to minor formatting differences between buyer and seller systems.
Yes — each reconciliation run processes one GSTIN's data. With a paid subscription, you can run as many reconciliations as needed — one per client, every month, with no additional charge.
Payment is processed securely via Razorpay. Once payment is confirmed, access is activated on your registered email immediately. If you face a payment issue where your card was charged but access was not granted, email auditdesk.hq@gmail.com with your Razorpay payment ID and we will investigate and resolve it. Please note that we do not offer automatic refunds — all sales are subject to our Terms of Service. For genuine technical issues, we will work to resolve them first.
