Terms & Conditions

Welcome to gstr1calculator.in. By using our website and services, you agree to comply with and be bound by the following terms and conditions. Please read them carefully before using the tool.

1. Nature of Service

We provide an automated data processing tool for Indian e-commerce sellers on Meesho, Amazon, and Flipkart. This is a utility tool, not a professional tax consultancy or CA service. We do not provide legal or tax advice. The output generated is meant to assist you in preparing your GSTR-1 data — the final responsibility for filing lies with the user.

We also offer an optional invoice generation feature — you may generate either a Generic Invoice, or a B2B GST Invoice if you need to claim Input Tax Credit (ITC) on your purchase. Using this feature is entirely your choice; it is not required to use the calculator.

2. Accuracy & User Responsibility

While we strive for 100% precision in our calculations, the final responsibility for GST filing lies solely with the user.

Users are strictly advised to cross-check all summarized data (Tables 7, 8, 12, and 13) with their original marketplace reports before submitting them on the GST portal. Errors in the source report (e.g. incorrect HSN codes set by the marketplace) will reflect in the output.

If you choose to generate a B2B GST Invoice, you are solely responsible for the accuracy of the GSTIN, business name, and address you enter. We generate the invoice exactly as entered and do not independently verify these details against government records.

3. Limitation of Liability

The developer (Sanathoiba Singha) and gstr1calculator.in shall NOT be held liable for any GST notices, penalties, interest, or legal actions taken by tax authorities arising from the use of this tool, including any denial or reversal of Input Tax Credit (ITC) resulting from incorrect invoice details entered by the user. We are not responsible for any financial losses, direct or indirect, resulting from reliance on the tool's output.

4. Refund Policy

Since we provide a digital service, refunds will only be considered in cases of verified technical failure where the report was not generated at all due to a fault on our end. Refund requests must be submitted within 24 hours of purchase with your Transaction ID to [email protected]. No refunds are issued once the report has been successfully processed and delivered. Current pricing and full refund conditions (including Bulk Mode and invoice-related scenarios) are detailed in our Refund & Cancellation Policy.

5. Data & Privacy

Your uploaded marketplace files are transmitted to our Cloudflare Worker backend solely for processing after payment confirmation. This data is never stored, logged, or retained after the result is returned. If you choose to generate a B2B GST Invoice, limited invoice details (GSTIN, business name, address, invoice amount) are retained separately, as required for GST compliance under Section 36 of the CGST Act, 2017. Please review our full Privacy Policy for details.

6. Permitted Use

This tool is intended for use by GST-registered Indian businesses and their authorized representatives. You may not reverse-engineer, reproduce, or resell the tool or its outputs. Use of the tool for filing false or fraudulent GST returns is strictly prohibited and may be reported to relevant authorities.

7. Governing Law

These Terms shall be governed by and construed in accordance with the laws of India. Any disputes arising from the use of this service shall be subject to the jurisdiction of courts in Assam, India.

8. Acceptance

By using this tool, you explicitly agree to these terms and acknowledge that you are using this tool at your own risk. Continued use of the service after any updates to these Terms constitutes acceptance of the revised version.
