GST Reconciliation Software | GSTZen

Reconciliation

Match what the government portal shows against what your books say, and find the mismatches before they turn into blocked Input Tax Credit. GSTZen handles fuzzy invoice numbers, rounding differences, and invoices that arrive a month or two late.

What GSTZen compares

Reconciliation is not one report. GSTZen runs the comparisons that actually decide your credit and your liability, and keeps the results side by side so you can see where a difference started.

What you can do

GSTR-2B vs Purchase Register

Compare every purchase invoice in your books against GSTR-2B to see exactly which credits are available, missing, or mismatched.

Input Tax Credit Reconciliation

Track ITC claimed, ITC available, and the gap between them across periods, so nothing is claimed twice or left behind.

GSTR-1 vs GSTR-3B vs Books

Spot differences between what you reported outward, what you paid, and what your sales register shows — before a notice arrives.

Multi-Month Rollover Matching

Invoices filed by suppliers in a later period are matched back to the month you booked them, instead of showing up as false mismatches.

Supplier Follow-Up Reports

Generate a vendor-wise list of invoices your suppliers have not uploaded, ready to email out and chase.

How reconciliation runs

Four steps, whether you are matching two hundred invoices or two hundred thousand.

1

Bring in your books

Import the purchase and sales registers from Tally, Excel, or your own software.

2

Pull portal data

GSTR-2A, GSTR-2B and your filed returns are fetched straight from the GST portal.

3

Match

Exact matches settle automatically; near matches on invoice number, date or value are flagged for a look.

4

Resolve and report

Accept, correct or park each difference, then export vendor-wise reports to chase.

Where every invoice lands

Nothing is left as an unexplained difference. Each line falls into one bucket, and you can see exactly why.

  • Exact matchInvoice number, date, taxable value and tax all agree. Nothing for you to do.
  • Probable matchThe same invoice, written differently — extra prefixes, leading zeroes, slashes or spacing. Matched, and shown to you for confirmation.
  • Value mismatchMatched invoice, different figures. Rounding differences within tolerance are settled automatically; real gaps are flagged.
  • Missing in GSTR-2BIn your books but not filed by the supplier. This is the credit at risk, and the list you send out.
  • Missing in booksFiled against your GSTIN but never recorded by you. Either a booking you missed or an invoice that is not yours.
  • Matched in a later periodThe supplier filed late. GSTZen ties it back to the month you booked it instead of reporting it twice.
