    Read the matches

    Bills are matched on supplier GSTIN, bill number and tax. Tax may differ by up to ₹1 for rounding. Each row says what to do next.

Where 2B meets your return

GSTR-3B working: outward supplies taken from GSTR-1 and eligible ITC, split into IGST, CGST and SGST.GSTR-3B working: outward supplies taken from GSTR-1 and eligible ITC, split into IGST, CGST and SGST.

Why it matters now

ITC you claim should be ITC in your 2B

Input tax credit is claimed in GSTR-3B, and GSTR-2B is the statement of what your suppliers reported. If a supplier hasn't filed, used a wrong GSTIN or typed a different amount, the credit you expect isn't in your 2B. Finding that on the 19th leaves no time to call the supplier; matching early does.

  • Supplier by supplier: bills missing from 2B are grouped by supplier, so one call can clear several bills.
  • Bill number noise ignored: prefixes, slashes and leading zeros don't break a match; you are asked to check only when the numbers really differ.
  • Ready for your CA: download the result as Excel and share it, or let your CA work from their free seat.

Reading the result

What each result means and what to do

The tool sorts every bill into one of five results. Matching inside Moharbill, with IMS accept and reject actions, is planned for v1.1 on Pro and Business at no extra cost.

Five results

From matched to only in 2B

ResultWhat to do
MatchedGSTIN, bill number and tax agree (within ₹1). Nothing to do.
Tax differsSame bill, different tax. Check the bill and any credit note, and ask the supplier which figure is right.
Check numberSame supplier and tax, but the bill number looks different. Usually a typo; confirm and mark it.
Only in your booksThe supplier hasn't reported it, or used a wrong GSTIN. Ask them before you claim the credit.
Only in 2BA purchase bill wasn't entered, or it belongs to another GSTIN of yours. Enter it or check the branch.

GSTR-2B guide

A monthly 2B routine that fits before the 20th

Most mismatches are not fraud or error on your side. They are timing and typing: a supplier files late, enters your branch's GSTIN, or keys in ₹18,000 where the bill says ₹1,800. The earlier in the month you see them, the more of them a phone call can fix.

  1. After the 14th: download GSTR-2B for the previous month once it is generated on the portal.
  2. Same day: export your purchase register for that month and run both through the free 2B tool.
  3. Call suppliers: start with Only in your books rows, largest tax first. Ask them to report the bill or correct the GSTIN.
  4. Enter what's missing: for Only in 2B rows, enter the purchase bill or move it to the right GSTIN.
  5. Before GSTR-3B: share the result with your CA so the ITC in GSTR-3B is the credit you can support.
Whether to claim, defer or reverse a credit for a mismatched bill is a decision for you and your CA. The tool shows the differences; it does not decide the ITC. Check with CA

FAQ

GSTR-2B questions

More in the help centre.

What is GSTR-2B?

GSTR-2B is a monthly statement on the GST portal of the input tax credit available to you, built from what your suppliers report in their GSTR-1 and similar returns. It does not change once generated for a period, which makes it the right statement to match your purchase register against.

Is the GSTR-2B reconciliation tool really free?

Yes. The free GSTR-2B reconciliation tool needs no sign-up. The files are read and matched in your browser and are not sent to or stored by us.

Which files does it accept?

The 2B JSON from the GST portal (also zipped) or the B2B sheet of the 2B Excel, and a purchase register as Excel or CSV with supplier GSTIN, bill number, date, taxable value and tax.

How does it match bills?

On supplier GSTIN, bill number and total tax. Bill numbers are compared without spaces, slashes, prefixes or leading zeros, and tax may differ by up to ₹1 for rounding.

Does Moharbill handle IMS (Invoice Management System)?

Not yet. Accepting, rejecting or keeping supplier invoices pending in IMS is part of the in-app 2B matching planned for v1.1. Until then, take actions on the GST portal and use the free tool to check the resulting 2B.

Can my CA use it for clients?

Yes. The free tool works for any GSTIN's files, and in Moharbill your CA has a free seat in each client's firm to export the purchase register.
