What it does

More depth than a spreadsheet can give you

A focused tool that does GST reconciliation thoroughly — built around the real work, from cleaning your data to confirming every rupee of ITC.

Hover or tap any card to see exactly what it does.

Pre-Check data-quality audit

Before matching, it cleans and checks your books — missing GSTINs, duplicates, tax that doesn’t add up and more — so problems are caught and fixed up front.

Pre-Check data-quality audit

Before matching, it cleans and checks your books — missing GSTINs, duplicates, tax that doesn’t add up and more — so problems are caught and fixed up front.

What Pre-Check looks for
  • Missing or invalid GSTINs — with a built-in validity check
  • Duplicate invoices
  • Tax higher than the taxable value
  • CGST and SGST that don’t match
  • IGST mixed with CGST and SGST on one line
  • Wrong tax type for the state — local vs inter-state
  • Blank or unreadable invoice numbers
  • A column-mapping report — how your file was read

Fix issues before they ever reach your return.

Depth — 20 outcomes, not just match / no-match

Every invoice is sorted into 20 clear outcomes — tax, date, GSTIN and amount differences, ITC, reverse charge, imports, ISD, duplicates and more — so you act only where it matters.

  • Pending ITC resolved
  • Not in Books / Not in Portal
  • Date, GSTIN & amount mismatches
  • ITC not available / reverse charge
  • Type mismatch / amendments
  • Imports / ISD / non-GST notes
  • Invalid GSTIN / self GSTIN / duplicate
  • Outside period / self-netting

Smart matching, including grouped invoices

Matches exactly, allows for small rounding differences, and can even match a group of invoices to a single portal entry — and the other way round.

How matching works
  • Exact invoice-to-invoice match
  • Allows small rounding differences (your tolerance)
  • Matches a group of invoices to one portal entry — and the reverse
  • Cleans up messy invoice numbers first

Catches matches a simple lookup misses.

Previous-period carry-forward

Invoices often reach the portal a month or two after you book them. GST ReconPro checks your earlier period too, so genuine matches aren’t wrongly flagged.

Previous-period carry-forward

Invoices often reach the portal a month or two after you book them. GST ReconPro checks your earlier period too, so genuine matches aren’t wrongly flagged.

Why it matters
  • Checks your earlier-period books for late-arriving invoices
  • Stops genuine matches being flagged “Not in Books”
  • Helps you claim ITC in the right period
  • Optional — switch it on when you need it

ITC claimed in the right month.

Pending ITC, watched to Section 16(4)

See every invoice you’ve booked that isn’t in GSTR-2B yet, how long it’s been waiting, and its Section 16(4) deadline — so you claim the credit before it lapses.

Pending ITC, watched to Section 16(4)

See every invoice you’ve booked that isn’t in GSTR-2B yet, how long it’s been waiting, and its Section 16(4) deadline — so you claim the credit before it lapses.

Why it matters
  • A running register of credit still to come, per client
  • Flags each invoice Open, At Risk or Lapsed against the 30-Nov deadline
  • When the supplier finally uploads, it’s matched automatically
  • Shows ITC recovered vs lost to late-filing suppliers, by financial year

Never lose ITC to a missed deadline.

How it works

From files to a clean report in three steps

1

Import

Load your books — straight from Tally, or an Excel export from BUSY, Marg, Zoho or any system — and the GSTR-2B / 2A file from the GST portal.

2

Pre-Check

One click scans your books and lists any data issues — missing GSTINs, duplicates, tax that doesn’t add up — to clean up first.

3

Reconcile

Match every invoice and sort the results into clear categories automatically — matches, mismatches and exceptions.

4

Review & export

Drill into what needs attention, confirm your ITC, and export a clean, organised Excel report.

Security & privacy

Built for the data you’re trusted with

Client financial data deserves care. Here’s exactly how GST ReconPro handles it.

Encrypted end to end

Every transfer to our servers is encrypted (HTTPS/TLS), so your data travels privately — never in the open.

Nothing is stored — by design

Reconciliation runs in memory on secure servers in India (AWS Mumbai) and is gone within seconds. There’s no database and no account where your invoices could be kept — the design leaves nowhere to store them. Everything you save — clients, history, reports — stays on your own computer.

Most of your work stays offline

Prepare your files, run Pre-Check and review past reports entirely on your computer. Only the final matching step goes online.

FAQ

Questions, answered

Which accounting systems does it work with?

It imports directly from Tally, or from an Excel export of BUSY, Marg, Zoho Books or any other system. It adapts to your column names and layouts automatically (including multi-sheet files), so you’re not tied to one system.

Can it read my existing Excel format of the inward register?

Yes — there’s no fixed template to follow. GST ReconPro reads your inward (purchase / ITC) register in whatever Excel layout you already use. It automatically detects your column headings and structure — even files with multiple sheets or extra heading rows — so you don’t need to rename columns, rearrange anything, or convert your data into a prescribed format. Just load the file as it is and the app adapts to you.

What do I need to run a reconciliation?

Two things: your purchase / ITC register (from Tally, or an Excel file) and the GST portal file for the same period — GSTR-2B or GSTR-2A, downloaded straight from the portal. You don’t need to reformat anything; load the files as they are and the app reads them directly.

What does it check, and what do I get back?

It matches your books against the portal invoice by invoice and sorts every line into one of 20 clear outcomes — exact matches, tax or value differences, GSTIN mismatches, invoices missing from your books or from the portal, RCM and invoice-type mismatches, amendments, pending ITC and more. You get a colour-coded detailed Excel report grouped by outcome, a one-line-per-invoice consolidated report for filtering or pivoting, and a summary with the ITC movement for the period.

What if an amount is off by a rupee or two?

Small rounding differences won’t be flagged as mismatches. The app matches within a rupee tolerance you can set (₹5 by default), so genuine differences stand out while paise-level rounding is ignored.

Will it change or overwrite my Tally or books data?

No. The app only ever reads your books — from Tally or Excel — and never writes anything back. Your accounting data and original files are left exactly as they are; the only thing it creates is the Excel report you download.

Can I reconcile several periods — and what about invoices that arrive late?

Yes. Each reconciliation is saved to your history, so you can run month after month and see the full picture. When a supplier uploads an old invoice late, it’s carried forward and matched automatically in a later period instead of showing up as an unexplained portal entry — nothing slips through the cracks.

What is Pending ITC and Section 16(4) tracking?

Pending ITC is the credit you’ve booked but that hasn’t appeared in GSTR-2B yet. The app keeps a running register of these invoices, shows how long each has been waiting, and flags it Open, At Risk or Lapsed against its Section 16(4) deadline (30 November of the following year) — so you can chase or claim the credit before it’s lost for good.

Can I manage more than one client?

Yes. You can keep a roster of clients and switch between them from the top of the app. Each client carries its own reconciliation history and pending-ITC register, so files and results never get mixed up between clients.

Is my clients’ data safe?

Nothing is stored — by design. Reconciliation runs in memory on secure servers in India (AWS Mumbai) and is gone within seconds; there’s no database or account where your invoices could be kept, and everything you save stays on your own computer. The connection is private, and every app update is checked to be genuine before it installs.

Do I need to be online?

An internet connection is needed to activate your licence and to run a reconciliation (the matching runs on our secure servers in India). Preparing your files, running Pre-Check and reviewing past reports all work offline.

How is it licensed? Is there a trial?

Licensing is per user, bound to one computer. A free trial is available — 7 days and 10 reconciliations — with no payment required. Your licence keeps working across updates, with no re-activation.

How do updates work?

The app updates itself in place. Each update is automatically checked to be genuine before it installs, and your existing licence carries over — nothing to re-enter.

What are the system requirements?

A Windows 10 or 11 PC (64-bit) and an internet connection for activation and reconciliation. There’s nothing to install on a server and no database to maintain — it runs as a normal desktop app.

How do I get a licence or support?
