How to Reconcile GSTR-2B

Reconciling a month takes a few minutes: you bring in the government's GSTR-2B for that return period, let Bizconnekt line it up against the bills you've already recorded, then work through the small number that don't match. This guide walks the whole thing end to end.

note

Availability depends on your plan and your role. GSTR-2B reconciliation is specific to businesses registered for GST in India.

If you're new to the idea, start with the Tax Compliance overview — it explains what reconciliation is and what each match state means.

Before you start​

You'll want two things in place:

  • Your purchase bills for the month, recorded in Bizconnekt. These are the "your side" of the comparison — the more complete they are, the cleaner the match. See Bills.
  • Your GSTR-2B for the return month, downloaded from the GST portal. This is the government's record of what your suppliers reported.

Step 1: Open Tax Compliance​

  1. Go to Finance from the sidebar.
  2. Click Tax Compliance.
  3. The reconciliation screen opens, organised by return month.

Step 2: Bring in your GSTR-2B for the month​

  1. Choose the return period you're reconciling — a single month, such as May 2026.
  2. Bring in that month's GSTR-2B.
  3. Bizconnekt reads every invoice in it and lists them for the month.

A few things worth knowing:

  • Reconcile one month at a time. Each return period is its own picture, matching the way GST returns work.
  • You can bring in more than once. If you download a fresh 2B later in the month (suppliers keep filing), bring it in again — Bizconnekt adds the new invoices to the same month rather than starting over.
  • Nothing is posted to your books by this. Bringing in a 2B only gives Bizconnekt something to compare against. Your bills and your accounts are untouched.

Step 3: Let Bizconnekt match, and read the result​

As soon as the 2B is in, Bizconnekt pairs each invoice against your recorded bills, matching on the supplier, the invoice number and the invoice value. You'll see a summary for the month — how many matched, how many didn't, and how many are waiting on one side or the other.

Read the summary top to bottom:

What you seeWhat it's telling you
MatchedYour bill and the 2B invoice agree. These need nothing from you.
MismatchSame supplier, same invoice — but the value differs. Bizconnekt shows both figures and the gap between them.
In your 2B, not in your billsThe supplier reported it; you haven't recorded it.
In your bills, not in your 2BYou recorded it; the supplier hasn't reported it (or reported it wrong).
Set asideLines you've parked, with your note on why.

A healthy month is mostly "matched" with a short list under everything else. That short list is your work.

Step 4: Work through the mismatches​

Deal with them by type — each has a clear next move.

A value that doesn't agree (mismatch)​

Bizconnekt shows your figure, the 2B figure and the difference. Decide which is correct:

  1. If your bill is wrong (a keying slip, a rounding, a missed charge), correct it in Bills. Reconcile again and it should pair up.
  2. If the supplier's filing is wrong, ask them to amend it. It'll clear once they refile and you bring in the updated 2B.

An invoice in your 2B you never recorded​

Your supplier reported a purchase you have no bill for:

  1. If it's a genuine purchase you missed, record the bill. Once it exists, it matches on the next run.
  2. If it isn't yours (wrong GSTIN at the supplier's end, or an error), query it with the supplier — don't record a bill for something you didn't buy.

A bill of yours that isn't in your 2B​

You have the bill, but the supplier hasn't reported it:

  1. Follow up with the supplier to file it (or correct how they filed it). Until they do, that credit isn't safe to claim.
  2. Keep the bill as it is — the fix is on the supplier's side, not yours.

Something you want to park​

For a duplicate, or anything you'll handle later, set the line aside and note why. It drops out of your active list but stays on record, so nothing is lost and you can come back to it.

Step 5: Confirm what's claimable​

Once the mismatches are handled, the invoices that are matched are the ones whose input tax credit you can claim with confidence. Your tax reports pull this together into the GST summary you file from — so a clean reconciliation this month means a claim you can stand behind.

Common issues​

Bills I know I recorded aren't matching​

  • Check the invoice number on your bill matches the supplier's exactly — a stray space, a prefix or a different format stops the pair.
  • Check the supplier's GSTIN on your bill is the right one.
  • Check the value — a small gap shows up as a mismatch rather than a match. Correct the bill and reconcile again.

The whole 2B shows as "not in your bills"​

  • Confirm you're looking at the right return month — a 2B brought in against the wrong period won't line up with that month's bills.
  • Confirm your bills for that month are actually recorded in Bizconnekt. Reconciliation can only match against bills that exist.

A supplier's invoice never appears in my 2B​

  • The supplier may not have filed for that period yet — 2B fills up as suppliers file. Bring in a fresh 2B later in the month.
  • If they've filed and it's still absent, they may have filed it under the wrong GSTIN or period. Follow up so they correct it.

The figures are close but flagged as a mismatch​

  • Reconciliation compares the full invoice value, tax included. A difference in tax, freight, a discount or rounding is enough to flag it. Check each part of the bill against the invoice to find where the gap is.
