What’s included in our GST return filing service

  • Collection of sales and purchase data in any format: Excel, Tally, Zoho, photos of bills
  • GSTR-2B and Invoice Management System reconciliation, with a list of suppliers who have not uploaded invoices
  • Preparation and filing of GSTR-1, IFF and GSTR-1A where needed
  • Tax computation, ITC set-off and challan preparation
  • Filing of GSTR-3B and sharing of acknowledgements
  • Monthly summary of tax paid, ITC claimed and mismatches
  • Reminders on WhatsApp and email before each due date

Why monthly reconciliation matters

Since GSTR-3B is now auto-filled from GSTR-1 and ITC is limited to GSTR-2B, small errors carry forward and trigger DRC-01B or DRC-01C notices. Returns also cannot be filed after three years from their due date. Regular reconciliation is the cheapest way to stay notice-free.
