Businesses in Mandaveli looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Mandaveli is a dense middle-class trading strip along R.K. Mutt Road, where provision stores, sweet stalls, silk and readymade shops, banks and the MTC bus terminus serve Mylapore's southern flank, with the Mandaveli Market feeding daily vegetable trade. Most shops are family-run B2C businesses hovering near the Rs.40 lakh goods threshold, so registration timing, composition scheme choice and GSTR-3B late fees dominate consultations. We serve this belt — including Mylapore and Raja Annamalaipuram — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Mandaveli regularly visit us for registrations, notice discussions and annual return reviews.
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.
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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
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 Mandaveli always know exactly what the engagement costs them.
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.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Kasturi Avenue is a residential street in Mandaveli, about 1.2 km south-east of the centre of Mandaveli. The same consultant covers the streets immediately around it — Santhome High Road (about 350 m); Rohini Gardens (about 500 m); DGS Dhinakaran Road (about 650 m); South Canal Bank Road (about 750 m) — so a site visit on Kasturi Avenue can usually be combined with other work in Mandaveli on the same trip. For GST purposes an address on Kasturi Avenue falls under the Chennai North CGST Commissionerate, and the Mandaveli pincode is 600028.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
Practical effect: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
25th GST Council Meeting, New Delhi — 18 January 2018 (PIB Release ID 1517140) · 2018-01-18
The Council reduced the late fee for failure to furnish GSTR-1 covering supply details, GSTR-5 for non-resident taxable persons and GSTR-5A for OIDAR suppliers to Rs 50 per day, and to Rs 20 per day for nil filers. Late fee for failure to furnish GSTR-6 by an input service distributor was set at Rs 50 per day. This extended the nil-filer distinction created for GSTR-3B at the previous meeting across the rest of the return forms.
Practical effect: Catching up on old GSTR-1 filings in Chennai costs Rs 50 a day, or Rs 20 a day where the return is nil, subject to the caps notified later.
TVH Lumbini Square Owners Association - AAR Tamil Nadu, Order No. 25/ARA/2019, dated 21 June 2019 · 2019-06-21
A residents welfare association collected monthly maintenance contributions from its members. The Authority held that where the contribution per member exceeds Rs. 7,500 a month, GST is payable on the entire contribution and not merely on the amount above Rs. 7,500. The Madras High Court subsequently held, in Greenwood Owners Association, that only the excess over Rs. 7,500 is taxable, and associations now follow that judicial position.
How we apply it: Chennai apartment associations should apply the High Court position carefully and keep member-wise workings ready for departmental scrutiny.
