Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
One WhatsApp message is how most of our client relationships began. Send yours today and have GSTR-1 & GSTR-3B Monthly Filing in Ambattur handled end to end from Rs.749 — fee confirmed in writing first, documents straight from your phone, acknowledgement the day we file.
We serve businesses on and around Sir Ivan Stedeford Hospital Road — 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. Ambattur hosts one of South India's largest small-scale industrial estates, where thousands of engineering, auto component, garment and fabrication units operate across the North and South phases off MTH Road and Ambattur-Red Hills Road. Job work movements between units demand disciplined ITC-04 and delivery challan records, while exporters and units crossing Rs.5 crore turnover must manage LUT filings and e-invoicing. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Ambattur follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Avadi and Padi 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.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Ambattur business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Ambattur business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
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 Ambattur would otherwise read about after it lapsed reaches our clients in time.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisories dated 11 April 2025 and 16 May 2025 — Table 3.2 of GSTR-3B · 2025-04-11
GSTN first advised that from the April 2025 period, auto-populated values in Table 3.2 of GSTR-3B, covering inter-state supplies to unregistered persons, composition taxpayers and UIN holders, would become non-editable, with corrections routed through GSTR-1A. After taxpayer representations, a 16 May 2025 advisory kept Table 3.2 editable for the time being. The locking was later subsumed in the broader hard-locking of GSTR-3B liability during 2025.
What to do about it: Report place-of-supply details correctly in GSTR-1 itself, since state-wise B2C figures in GSTR-3B are moving beyond manual correction.
Circular No. 123/42/2019-GST dated 11 November 2019 · 2019-11-11
CBIC explained the newly inserted rule 36(4). The restriction is not supplier-wise but is computed on a consolidated basis for all invoices not appearing in GSTR-2A. The amount of eligible credit is determined from GSTR-2A as on the due date for filing GSTR-1 by suppliers for that month. A taxpayer may therefore claim only twenty per cent more than the credit reflected in GSTR-2A, and the balance may be claimed in a later month once the supplier uploads the invoice.
What it means for you: This circular began the era of credit being tied to supplier filings, and monthly reconciliation of purchases with GSTR-2A or 2B is now unavoidable.
Union of India v. Bharti Airtel Ltd — Supreme Court, 2021 · 2021-10-28
Bharti Airtel sought to rectify its GSTR-3B for July-September 2017 to claim refund of about Rs 923 crore excess cash paid, blaming the non-operational GSTR-2A at the time. The Supreme Court set aside the Delhi High Court order permitting rectification, holding that returns can only be corrected in the period in which errors are noticed, as the law then stood, and that taxpayers must self-assess from their own books, not the portal.
Why this matters: File GSTR-3B accurately the first time — correct discovered errors in the current period per the prescribed mechanism rather than expecting retrospective revision of old returns.
