The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Kolathur permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Retteri — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
Kolathur is India's best-known ornamental fish hub, with breeding farms and aquarium shops clustered off Red Hills Road near Retteri junction, alongside hardware stores and construction material suppliers serving fast-growing residential pockets like Poombuhar Nagar. Many fish breeders and online sellers cross the Rs.40 lakh goods threshold without realising it, making first-time registration and e-commerce reporting the local GST pain point. GST compliance in a market like Kolathur rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Kolathur and nearby Villivakkam and Perambur on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Kolathur. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Kolathur always know exactly what the engagement costs them.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
At month end we remind you and collect sales invoices, purchase bills and credit notes in whatever format you maintain, including Excel, Tally exports or scanned copies.
We prepare invoice-wise outward supply details, validate GSTINs of your B2B customers, summarise B2C supplies and file GSTR-1 on the portal before the 11th.
We download your auto-drafted GSTR-2B, match it against purchase records, and claim only eligible input tax credit so that mismatches do not trigger scrutiny notices later.
We compute net tax payable after ITC set-off, share the working with you for approval, and generate the payment challan for any cash liability.
After your confirmation and tax payment, we file GSTR-3B before the 20th and send you both filed acknowledgements along with a one-page summary of the month.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.

Practical outcomes our clients measure us by.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Supplier defaults | Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit. | Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult. |
| Refund claims | RFD-01 filed with complete statements and annexures, tracked from ARN to bank credit, with any deficiency memo answered promptly. | Incomplete claims bounce back as deficiency memos while the refund sits unclaimed for months and working capital stays blocked. |
| Risk of notices | GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices. | Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice. |
| Annual return preparation | Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year. | Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| Portal credentials and data | Logins handled by a small engaged team under strict confidentiality, with credentials stored securely and never passed onward. | Passwords circulating on chats with freelancers and part-timers, and no accountability for who has accessed your business data. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Mr. Kannippan Arumugan v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 2943 of 2026, decided 30 January 2026 (C. Saravanan J.) · 2026-01-30
The taxpayer had reported tax of Rs 2,54,040.30 against an invoice instead of the correct Rs 1,31,280.30, and a demand followed. The Court quashed the assessment order dated 21 July 2025 and remitted the matter for fresh adjudication within six months, permitting the petitioner to rectify the inadvertent error subject to compliance with Circular No. 212/6/2024-GST, and directing the officer to verify with the recipient's jurisdiction whether excess credit had in fact been availed.
Why this matters: A clerical overstatement in GSTR-1 by a Chennai supplier can still be corrected long afterwards, provided the recipient has not taken the excess credit and the Circular 212 procedure is followed.
35th GST Council Meeting, New Delhi — 21 June 2019 · 2019-06-21
At the first meeting chaired by Finance Minister Nirmala Sitharaman, the Council decided to introduce an electronic invoicing system in a phase-wise manner for business-to-business transactions. The press release recorded that e-invoicing would help taxpayers with backward integration and automation of tax-relevant processes and would help authorities combat evasion, with Phase 1 proposed to be voluntary and rolled out from January 2020. This decision is the origin of the Invoice Registration Portal, the IRN and the QR code now mandatory for most mid-sized and large businesses.
Why this matters: Every later e-invoicing threshold reduction, down to the Rs 5 crore limit now applicable, traces back to this decision, so businesses crossing a threshold must set up e-invoicing from the first day of the next financial year.
GSTN Advisory, 2022 — Table 3.1.1 of Form GSTR-3B introduced by Notification No. 14/2022-Central Tax, dated 5 July 2022 · 2022
Table 3.1.1 was added to GSTR-3B so that supplies notified under Section 9(5), such as passenger transport, restaurant service supplied through an app, hotel accommodation and housekeeping, are reported separately. The e-commerce operator reports the value and pays the tax in row (i), while the underlying supplier reports the same value in row (ii) and pays nothing on it, so the turnover is not counted twice across the two returns.
How we apply it: Chennai restaurants and cab operators supplying through an app must still report those sales in Table 3.1.1(ii) even though the platform pays the tax.
