GSTR-1 & GSTR-3B Monthly Filing in Porur does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Ganesh Nagar — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Porur commands the junction of Mount Poonamallee Road and Arcot Road, the gateway to Chennai's western IT corridor, with the Sri Ramachandra medical campus, IT offices, construction firms and logistics yards nearby. IT and ITES exporters need LUT filings under RFD-11 each financial year and refunds through RFD-01, while contractors face Section 17(5) credit blocks and site-to-site e-way bills. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Porur follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Valasaravakkam and Ramapuram 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.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Porur are never held up by a compliance gap at the gate.
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.
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 Porur would otherwise read about after it lapsed reaches our clients in time.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.
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.
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.
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.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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.
Circular No. 209/3/2024-GST · 2024-06-26
Clarifying the new clause (ca) of Section 10(1) of the IGST Act, CBIC stated that when goods are supplied to an unregistered person and the billing address differs from the delivery address, the place of supply is the delivery address recorded on the invoice. This principally affects e-commerce transactions, where a buyer may bill in one State and ship to another, and determines whether the seller charges CGST-SGST or IGST.
Practical effect: E-commerce sellers must configure invoicing so tax type follows the delivery address, not the billing address, to avoid wrong-tax demands and refund complications.
Saro Enterprises - AAR Tamil Nadu (2018), upheld by AAAR Tamil Nadu, order dated 6 February 2019 · 2018
The applicant made polypropylene and recycled plastic trays used by farmers to raise paddy and vegetable seedlings, and argued that they were agricultural implements. The Authority held that the trays are other articles of plastic under heading 3926 90 99 and are taxable at 9 percent central tax and 9 percent State tax. Use in agriculture does not by itself bring a product within the exempt agricultural implements entry, and the material and the tariff description prevail over the end use.
Why this matters: Chennai suppliers to the farm sector cannot assume exemption merely because the buyer uses the product in agriculture.
GSTN rollout of Form GSTR-1A pursuant to Notification No. 12/2024-Central Tax, dated 10 July 2024 · 2024-07
Through Notification No. 12/2024-Central Tax and subsequent portal rollout, Form GSTR-1A was reintroduced. It lets a taxpayer amend or add records of the same tax period after filing GSTR-1 but before filing that period's GSTR-3B, so the corrected liability auto-populates into GSTR-3B. Amendments flow to the buyer's GSTR-2B of the next period, and the recipient GSTIN itself cannot be changed through GSTR-1A.
Practical effect: Use GSTR-1A to fix invoice errors in the same month instead of carrying mistakes forward, especially now that GSTR-3B figures are hard-locked.
