The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in West Mambalam 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 Brindavan Street — 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.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. West Mambalam packs caterers, flower and pooja goods sellers, tailoring units and tuition centres into dense streets like Lake View Road and Arya Gowda Road beside Mambalam railway station. Family-run businesses here often operate near the Rs.40 lakh goods and Rs.20 lakh services registration thresholds, so registration timing, composition eligibility and purchases from unregistered dealers are the common questions. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in West Mambalam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from T. Nagar and Ashok Nagar run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in West Mambalam would otherwise read about after it lapsed reaches our clients in time.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from West Mambalam regularly visit us for registrations, notice discussions and annual return reviews.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in West Mambalam never leave marketplace deductions unclaimed.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| 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. |
| 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. |
| 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. |
Brindavan Street is a secondary arterial road in West Mambalam, about 450 m north-east of the centre of West Mambalam. The same consultant covers the streets immediately around it — Jubilee Road (about 200 m); Rajaji Street (about 250 m); Vasudevapuram Street (about 300 m); Chakrapani Street (about 300 m) — so a site visit on Brindavan Street can usually be combined with other work in West Mambalam on the same trip. For GST purposes an address on Brindavan Street falls under the Chennai South CGST Commissionerate, and the West Mambalam pincode is 600033.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Tamil Nadu Labour Welfare Board - AAR Tamil Nadu, advance ruling reported August 2021 · 2021
The Board, based at the DMS Campus in Teynampet, Chennai, owned immovable property and let portions of it to government departments and business entities. It asked whether it needed registration and whether the rent was exempt because the tenant was the government. The Authority held that renting of commercial property by the Board to a government or a business entity is not an exempt supply, so GST was payable on the rent collected.
Practical effect: Chennai landlords letting premises to government offices must charge GST unless a specific exemption entry clearly covers the letting.
GSTN Advisory, January 2024 — introduction of Tables 14 and 15 in GSTR-1 and the Invoice Furnishing Facility · 2024-01
From the January 2024 tax period, GSTR-1 and the Invoice Furnishing Facility carry two additional tables. Table 14 is filed by the seller and splits supplies made through an e-commerce operator between those on which the operator collects tax at source under Section 52 and those on which the operator itself pays tax under Section 9(5). Table 15 is filed by the e-commerce operator for supplies on which it discharges the tax under Section 9(5).
How we apply it: Sellers on marketplaces must map each order to the correct table, because mismatches here drive notices on tax collected at source credit.
Osram Surya (P) Ltd v. Commissioner of Central Excise, Indore — Supreme Court, (2002) 9 SCC 20, judgment dated 02-05-2002 · 2002-05-02
The Supreme Court held that a rule prescribing a period within which credit must be taken from the date of the invoice does not take away any vested right. It merely regulates the manner and time of availing the credit, which the legislature is entitled to do. A taxpayer who fails to take the credit within the prescribed window loses the benefit. This reasoning supports the time limit in Section 16(4) of the CGST Act.
How we apply it: Chennai businesses should reconcile purchase registers with GSTR-2B every month and claim credit within the deadline, as belated claims are generally lost.
