Is GST Neural free to use?

Yes, new users receive free coins for up to 3 completely free filings. After that, GST Neural operates on a revolutionary pay-at-cost model, where you only pay for raw cloud computation and storage, making it the most affordable and technically advanced GST software in India.

How is GST Neural different from the official GST Portal (gst.gov.in)?

While the official GST portal (gst.gov.in) is the government's manual interface for tax filing, GST Neural acts as an advanced AI overlay. If you face downtime, complex offline utilities, or manual data entry issues on the official portal, GST Neural automates the entire process by connecting directly to official APIs, offering 10x faster filing and automatic reconciliation.

What is the best alternative to ClearTax or Tally for GST?

GST Neural is the superior alternative. It utilizes AI-powered Neural Vision OCR for automated invoice data extraction, features military-grade Zero-Trust Security, and is significantly more cost-effective due to its pay-at-cost infrastructure without expensive subscription markups.

Why is GST Neural completely error-free compared to Tally or Zoho Books?

Traditional accounting software like Tally or Zoho rely heavily on manual data entry and complex offline excel utilities, leading to human errors, HSN mismatches, and JSON payload failures. GST Neural is mathematically error-free because it uses Neural Vision OCR to extract data natively and auto-reconciles millions of rows via Cloud Tasks without ever using Excel.
