From first-time registration under the GSTN portal to monthly GSTR-1 and GSTR-3B filings, annual reconciliation and notice responses, MAM Biz Solutions handles every GST obligation so nothing falls through the cracks and no late fee lands on your desk.
Under the GST framework, late filing attracts interest at eighteen percent per annum on the unpaid tax liability, plus a late fee of fifty rupees per day per return. That clock starts running from the due date, not from the date you realise the return is overdue. For a business filing monthly across multiple GSTINs, a single missed cycle can compound into a significant penalty before anyone notices.
Beyond the financial hit, non-compliance blocks your ability to claim Input Tax Credit. Suppliers who fail to file GSTR-1 on time cause their buyers to lose ITC entitlement in GSTR-2B, a knock-on effect that can disrupt your working capital and strain vendor relationships. The GST department has also increased scrutiny notices under ASMT-10, DRC-01 and scrutiny of returns, and responding to these requires a detailed audit trail of every invoice, every credit and every reconciliation entry. Staying clean is far cheaper than catching up.
Whether you are filing for the first time or untangling a backlog of missed returns, our scope covers registration, monthly filings, annual returns, reconciliation and notice management.
We apply for your GSTIN through the GSTN portal, handle the business verification, upload documents and follow up until the registration certificate is in hand. Includes advice on the correct legal name, HSN/SAC code selection and the right registration type for your business model.
Outward supply details filed in GSTR-1 and the consolidated summary return in GSTR-3B, filed before the due date every month. We reconcile your sales data with the return before submission to catch mismatches before the department does.
The annual consolidation of all monthly and quarterly returns, reconciled with your audited financials and filed before the December deadline. Catches and corrects any discrepancies between GSTR-1 and GSTR-3B before they attract a scrutiny notice.
Input Tax Credit available in GSTR-2B is matched against your purchase register to identify unreconciled credits before they lapse. Prevents overpayment of output tax and protects your working capital from unnecessary cash outflow.
ASMT-10 scrutiny notices, DRC-01 demand notices and intimation letters from the GST department are responded to with a detailed written reply, supporting documents and any required amended returns, filed within the statutory response window.
Businesses operating across states carry a separate GSTIN for each state of registration. We manage filing calendars, due date tracking and reconciliation across all GSTINs so no registration slips into non-compliance while you focus on operations.
Return type depends on your registration category and turnover. The table below maps the most common situations to the applicable form and its due date.

Our process is designed to require the minimum possible effort from your team. You share data once; we handle everything from there.
We collect your GSTIN, credentials and purchase and sales registers in a shared folder. A dedicated filing specialist is assigned who stays with your account throughout.
Sales data is matched against GSTR-2B auto-populated credits. Any mismatch between your books and the department's portal data is flagged to you with a clear explanation before the return is filed.
GSTR-1 and GSTR-3B are prepared, cross-checked for arithmetic accuracy and HSN summary completeness, and reviewed by a senior CA before submission.
Returns are filed before the due date. You receive a filed acknowledgement and a copy of the filed return within twenty four hours of submission.
We monitor your GSTN portal for department notices, auto-populated liability in DRC-01A and any changes to your return status. Alerts are sent to you before deadlines arrive, not after they pass.
Our GST retainer covers the complete compliance calendar for your GSTIN. There are no add-on charges for reconciliation or notice responses that arise from returns we filed.
Share your GSTIN and business details and a GST specialist will call you within one working day with a clear plan, a fixed monthly fee and a start date.
