GSTR1 Calculator: The Complete Guide for E-commerce Sellers
Filing GSTR-1 as an e-commerce seller on Meesho, Amazon, or Flipkart can be overwhelming — hundreds of orders, multiple states, different tax rates, and a GST portal that expects a very specific format. Our GSTR-1 Calculator is built specifically to solve this problem.
Who Is This For?
This tool is built for Indian e-commerce sellers registered under GST who sell on:
Meesho — process Sales and Returns reports together for accurate Net Sales
Amazon — supports both B2C and B2B sales, transaction-wise reports, and ready-to-file reports
Flipkart — upload your Tax Report directly without any conversion or export steps
What Output Do You Get?
After processing, you get a downloadable Excel file with all the tables you need for GSTR-1:
Platform Summary — taxable value, CGST, SGST, IGST per platform
State-wise Summary (Table 7) — inter-state and intra-state breakdown by tax rate
Nil-Rated Summary (Table 8) — 0% GST sales, intra and inter-state
HSN-wise Summary (Table 12) — quantity, taxable value, and tax split by HSN code
Document Summary (Table 13) — invoice count, cancelled invoices, net issued per platform
Amazon B2B Sales — Now Supported
Many Amazon sellers receive both B2C (individual customer) and B2B (business buyer with GSTIN) orders. Our updated calculator now handles both types automatically from your Amazon tax report. No manual splitting, no extra files required.
Amazon & Flipkart Transaction-wise and Ready-to-File Reports
We now support both formats that Amazon and Flipkart provide — transaction-wise reports (detailed row-by-row) and ready-to-file reports (pre-summarised). Upload whichever format you have from your seller panel and our calculator will process it correctly.
Flipkart — Direct Upload, No Conversion Needed
Previously, Flipkart Tax Reports required extra steps to remove file protection before uploading. Our updated calculator can now read the original Flipkart file directly — just download from your seller panel and upload as-is. No Google Sheets, no copy-paste, no export needed.
Important Note for Meesho Sellers
Since Meesho Sales Reports do not provide specific Invoice Numbers, the Document Summary (Table 13) will only display the total count of issued and cancelled invoices. The Invoice Start and Invoice End columns will remain blank. All other sections — B2C, State Wise Summary, and HSN Summary — are fully generated.
Why Not Just Use a CA or Manual Calculation?
Cost: CA fees for monthly GST filing can run ₹500–₹2000/month. Our tool costs ₹99/month.
Speed: Manual state-wise calculation from hundreds of orders takes 1–2 days. Our tool does it in under 4 minutes.
Accuracy: Manual errors in state classification or HSN grouping can attract GST notices. Our engine applies consistent rules every time.
Privacy: Your sales data never leaves your device — all calculation happens in your browser.
Pricing
Monthly Report: ₹99 — generate GSTR-1 summary for any single month
Quarterly Report: ₹249 — upload 3 months of data and generate a combined quarterly GSTR-1 summary
Payment is processed securely via Razorpay. Your GSTR-1 summary generates and downloads automatically after payment confirmation.
⚠️ Disclaimer: This is an automated calculator tool. Always verify the generated data before filing on the GST portal. The developer is not liable for any penalties or issues arising from use of this tool. Data accuracy depends on the completeness and correctness of uploaded platform reports.
