Complete GSTR-1 & GSTR-3B Monthly Filing in Guindy from Rs.749 — documentation, preparation, filing and acknowledgement, all managed by one accountable team. One call or WhatsApp message starts the process, and you get a same-working-day response.
We serve businesses on and around Developed Plots Industrial Estate — 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.
Guindy is Chennai's manufacturing and engineering heartland, from the SIDCO and Thiru Vi Ka industrial estates to IT parks such as Olympia Technology Park off Mount Poonamallee Road. Factories juggle job-work documentation, RCM on goods transport agency freight and 18 per cent interest exposure when GSTR-2B mismatches force ITC reversals, making monthly purchase reconciliation non-negotiable. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Guindy, Saidapet and Alandur on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
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.
Consistent, reconciled returns give the department's matching systems nothing to flag. Clients who move to us after years of self-filing typically see scrutiny queries and mismatch notices fall away within a few filing cycles.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
| 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. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Goodwill Industrial Canteen - AAR Tamil Nadu, Order No. TN/09/AAR/2018, dated 30 August 2018 · 2018-08-30
The applicant prepared food and served it in the canteens of client companies at their premises. It sought the rate applicable to this arrangement. The Authority held that the supply of food and beverages on the premises of an industrial undertaking was taxable at 18 percent up to 26 July 2018 and at 5 percent from 27 July 2018, when the restaurant service entry was amended to cover canteens at offices and factories, the concessional rate being available without input tax credit.
How we apply it: Chennai canteen contractors should bill factory and office canteens at 5 percent and forgo input tax credit on their purchases.
GSTN Advisory dated 7 June 2025 — barring of GST returns after three years (Finance Act, 2023; Notification No. 28/2023-Central Tax) · 2025-06-07
Implementing the Finance Act, 2023 amendments to Sections 37, 39, 44 and 52, notified by Notification No. 28/2023-Central Tax, GSTN advised that from the July 2025 tax period the portal blocks filing of GST returns once three years have passed from their due date. The bar covers GSTR-1, GSTR-1A, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. Taxpayers with old pending returns were urged to reconcile their records and file before the returns became permanently time-barred on the portal.
Why this matters: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
Circular No. 187/19/2022-GST · 2022-12-27
Where a resolution plan is approved by the adjudicating authority under the Insolvency and Bankruptcy Code and the government's claim is scaled down, the tax department cannot continue to pursue the original demand. The Board directed officers to give effect to the approved plan by issuing an intimation in FORM GST DRC-25 under Rule 161, reducing the demand in the recovery records to the amount admitted in the plan, and to close recovery proceedings for the balance.
Why this matters: If a Chennai company has come out of insolvency, insist on a DRC-25 intimation so that the old demand stops appearing in the recovery register and blocking registration or refunds.
