Monthly GSTR-1 & 3B Filing

Each month I need both GSTR-1 and GSTR-3B prepared and filed for my business. I will give you clean exports of sales and purchase invoices in Excel straight from my accounting software. Before anything is submitted, I want those figures matched against the auto-populated data on the GST portal for both outward and inward supplies so that any discrepancy is caught early. Once the reconciliation is clear, go ahead and complete the filing on the portal, generate the challan if tax is payable, and send me the acknowledgements. Tally, Busy, Zoho Books or similar tools are fine on your side as long as the final upload happens smoothly through the GST portal utilities. Deliverables each month • Reconciled working file showing any mismatches for sales and purchases • Filed GSTR-1 and GSTR-3B PDFs with ARN/acknowledgement numbers • Payment challan (if generated) and confirmation of successful submission I prefer to see draft figures within three working days of month-end so there is time to resolve issues before the statutory due date. Accuracy in reconciliation is critical; a clean match with the portal is my acceptance criteria.
