GST filing that doesn't leave credit on the table

GST compliance sounds simple until you're actually running it — outward supply returns, inward credit matching, e-invoicing thresholds, and a due date every month that doesn't move for anyone. Most founders don't lose sleep over the filing itself; they lose money on the reconciliation nobody does properly, where genuine input tax credit quietly goes unclaimed because a vendor's GSTR-2B doesn't match the books.

We file your GSTR-1 (outward supplies) and GSTR-3B (summary return with tax payment) every month, and — critically — reconcile your purchase register against GSTR-2B before we file, so credit mismatches are caught and chased down while they're still fixable, not discovered nine months later during a departmental audit.

Why reconciliation matters more than filing

Filing a return on time is table stakes. The real value is in the reconciliation — catching a vendor who hasn't filed, a credit note that was missed, or an invoice booked in the wrong period — before it becomes a demand notice with interest and penalty attached.

What you get

What's included

A single monthly engagement covers the full return cycle, not just the filing:

GSTR-1 filing

Outward supply return prepared and filed from your sales register every month.

GSTR-3B filing

Summary return with accurate tax liability computation and timely payment.

2B reconciliation

Purchase register matched against GSTR-2B to catch every eligible input credit.

Vendor follow-up

We flag non-filing vendors so credit isn't silently lost on your end.

E-invoicing support

IRN generation and e-invoice compliance if you're above the applicable threshold.

Annual return (GSTR-9)

Year-end annual return and reconciliation statement where applicable.

How it works

How we run your GST compliance

1. Books handover

You share sales and purchase data (or we pull it directly if we also run your bookkeeping) by the 5th of each month.

2. Reconciliation & review

We match your purchase register against GSTR-2B, flag mismatches, and confirm the liability with you before anything is filed.

3. Filing & payment

GSTR-1 and GSTR-3B are filed within the statutory window, with payment challans generated and shared for your records.

Typical timeline

Once onboarded, your monthly cycle runs on a fixed calendar — reconciliation by the 15th, filing well before the 20th deadline, every month without exception.

Answers

Frequently asked questions

What if my vendor hasn't filed their GST return?+
We flag it immediately during reconciliation — you can withhold payment or follow up before the credit is permanently lost in a later tax period.
Do you handle multiple GSTINs across states?+
Yes, we manage multi-state GST registrations under a single engagement with consolidated reporting.
What happens if a return is filed late?+
Late filing attracts late fees and interest on any tax due. We build in buffer days specifically to avoid this — our default calendar targets filing well ahead of the deadline.
Can you fix past reconciliation issues, not just going forward?+
Yes — we regularly do backlog reconciliation for new clients to recover missed credit from earlier periods, within the time limits the law allows.
