GST reconciliation for modern finance

Parakh matches your purchase register against GSTR-2B, shows which input tax credit is at risk and why, and writes the follow-up email to every supplier who needs to fix their return.

Reads the files your team already exports. No templates, no reformatting.

Finance teams match thousands of invoices every month, but most of that time goes into just looking.

See a month reconciled, start to finish

Upload a register, match it against GSTR-2B, find the credit at risk and email the suppliers who owe it. Fifty-four seconds, on sample data.

Reconciliation

Match any register to the portal, as is

Upload the Excel your accounting system exports. Parakh finds the header row, maps the columns, sums multi-rate lines and remembers the layout for next month. GSTR-2B, GSTR-2A and GSTR-1 are all supported.

How matching works

5matching passes, from exact to same-PAN

Supplier follow-ups

Chase the suppliers who owe you credit

Every supplier gets one email listing each invoice they need to file or amend, with the ITC on hold, and a link to answer per invoice without signing up. Their replies, and next month's carry-forward, land on the invoice.

Follow-ups and vendor scores

A–Dcompliance grade for every supplier, every period

ITC protection

Know your credit before you file 3B

Parakh flags unpaid invoices past 180 days, blocked credit, reverse charge and IGST charged where CGST and SGST were due. Enter what you claimed in GSTR-3B and see the excess against 2B straight away.

ITC rules we check

13reason codes on every invoice

IMS and month-end close

Decide every invoice, then lock the month

Apply suggested IMS actions in one click, export the action list, and lock the period when you file. Every change is in the audit log, and invoices still open carry forward to next month on their own.

What other reconciliation tools leave to you

01 · Supplier replies

Suppliers answer in one click

Every follow-up carries a no-login link. The supplier marks each invoice filed, amended, to be filed in a month, or disputed, and the answer lands on the invoice.

02 · Credit clock

Never lose credit to a date

Section 16(4) lapse, Rule 37's 180 days and the IMS one-period limit for Pending, on every open invoice, with a Monday email of what is due.

03 · Payment advice

Pay what the portal supports

Release the value, hold only the GST that has not reached 2B. MSME suppliers are flagged against the 45-day rule of Section 43B(h).

04 · Year view

The whole year on one page

Books, 2B and 3B month by month for each client, ready for GSTR-9 Tables 8A to 8D, with what is still recoverable.

05 · Client links

Share without sharing a login

Send a client a read-only summary that expires in 7, 30 or 90 days. No notes, no team names, revocable any time.

06 · Month on month

See what changed since last month

Every period shows secured credit, risk and match rate against the previous one, and the exact characters that differ between invoice numbers.

What Parakh checks

The questions your auditor will ask

Is it in GSTR-2B?

Missing invoices grouped by supplier, with the credit on hold and a draft email to chase them.

Do the amounts agree?

Taxable value, total tax and each head compared to the paisa, within the tolerance you set.

Is the place of supply right?

IGST charged on an intra-state purchase, or CGST and SGST on an inter-state one, is flagged.

Has it been paid in 180 days?

Map a payment-date column and unpaid invoices past 180 days move to ITC at risk for reversal.

Is the credit even eligible?

Section 17(5) blocked credit and reverse charge supplies are separated from ITC you can claim.

Was it booked twice?

Duplicate lines in the register and invoices filed under another GSTIN of the same PAN are caught.

Questions

Do I need to give Parakh my GST portal login?

No. Download GSTR-2B (or 2A, or GSTR-1) as JSON from the GST portal and upload it. Parakh never asks for or stores portal credentials.

Our register looks nothing like a template. Will it work?

Yes. Parakh detects the header row even under title rows, maps columns by name (Tally, Busy, Zoho, SAP and hand-made sheets all work), and lets you correct anything before running. The layout is remembered for next month.

How is this different from the matching on the GST portal?

The portal compares exact invoice numbers. Parakh normalises formats, catches near-identical numbers, sums multi-rate lines, compares each tax head, applies the 180-day and blocked-credit rules, and carries open items across periods. It then drafts the supplier emails.

What happens to our data?

Uploaded files are deleted after 7 days. Results stay in your workspace until you delete them or your retention setting removes them. You can export everything at any time. See the privacy notice and data processing addendum.

Can our CA and our team both use it?

Yes. Invite people as admins, members (who reconcile and follow up) or viewers (read only). CA practices can keep every client GSTIN in one workspace.

Is the price inclusive of GST?

Prices are before 18% GST. You get a GST tax invoice for every payment, with CGST and SGST or IGST depending on your billing GSTIN.
