Yes! We offer a Developer Trial plan that's completely free with 300 requests per month, 15 requests per day, and 1 request per second rate limit. This allows you to test our API without any commitment. For higher usage, we have paid plans starting at ₹999/month.

Our data is sourced from official CBIC and GST Council notifications and is updated regularly to ensure accuracy and compliance with current tax regulations. We strive to stay in sync with the latest government notifications to keep our data fresh and relevant.

I typically respond to emails within 24-48 hours. For urgent technical issues, I aim to respond within 4 hours during business hours (IST).

Due to the digital nature of our services, we generally do not provide refunds for API usage that has already been consumed. However, we may consider refunds in exceptional circumstances like service unavailability, billing errors, or duplicate charges. Please see our Refund & Cancellation Policy for complete details.

Yes, you can cancel your subscription at any time through your account dashboard or by contacting us. Cancellation takes effect at the end of your current billing period, and no additional charges will be applied after cancellation.

We're actively developing a comprehensive GST-compliant invoicing platform. While I can't provide an exact launch date, it's expected to be available within the next 6 months.
