Complete GSTR-1 & GSTR-3B Monthly Filing in Medavakkam 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.
Share your number — a senior GST consultant calls you back within 30 minutes.
Businesses in Medavakkam looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Medavakkam's junction links Velachery, Tambaram, Sholinganallur and Mambakkam, making it one of south Chennai's fastest-selling apartment markets, ringed by builders, hardware and sanitaryware dealers, supermarkets and tuition centres along Medavakkam Main Road and the Sholinganallur route. Promoters using the 1 and 5 per cent residential rates must source at least 80 per cent of inputs from registered suppliers or pay tax on the shortfall under reverse charge. We serve this belt — including Pallikaranai and Madipakkam — 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.
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.
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.
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 Medavakkam are never held up by a compliance gap at the gate.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.
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.
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.
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.
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.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
GSTN Advisory, November 2024 — 30-day IRP reporting limit for AATO Rs 10 crore and above · 2024-11
GSTN advised that from 1 April 2025, taxpayers with annual aggregate turnover of Rs 10 crore and above cannot report e-invoices on the Invoice Registration Portals beyond 30 days from the document date. The restriction, earlier applicable only to very large taxpayers of Rs 100 crore and above, covers invoices, credit notes and debit notes. The IRP validation simply rejects documents older than 30 days, so late reporting becomes impossible.
How we apply it: Automate same-day or same-week IRN generation, because an invoice missed beyond 30 days cannot be e-invoiced at all and endangers the buyer's ITC.
LC Infra Projects (P) Ltd v. Union of India — Karnataka High Court, judgment dated 22 July 2019 · 2019-07-22
The department demanded interest for delayed payment of tax and attached the taxpayer's bank account without first issuing any show cause notice. The High Court held that issuance of a show cause notice is a mandatory pre-condition before recovery of interest, because the taxpayer must have an opportunity to dispute the period and the computation. The recovery action and the bank attachment were quashed, with liberty to the department to proceed afresh after proper notice.
Practical effect: Interest cannot be lifted from your bank account without warning — insist on a show cause notice and a chance to verify the calculation.
34th GST Council Meeting (video conferencing) — 19 March 2019 · 2019-03-19
The Council gave promoters a one-time option to continue paying tax at the old effective rates of eight or twelve per cent with input tax credit on ongoing projects, meaning buildings where both construction and actual booking had started before 1 April 2019 and which were not completed by 31 March 2019. The option had to be exercised once within a prescribed time frame, failing which the new rates applied automatically. Credit for projects moving across was to be transitioned pro rata.
Practical effect: Chennai builders who did not formally exercise the option in 2019 are on the one and five per cent no-credit rates, and any credit claimed since then is exposed to reversal.
