Sound familiar?

⚠ Stitching together GST CGST/SGST splits, HSN codes, e-way bills and IRP / IRN — four moving parts, four different schemas, all GSTN-controlled
⚠ Catching PAN / GSTIN typos before they hit the IRP — once an IRN is generated it can only be cancelled within 24 hours
⚠ Adapting global AI tools to the urban Indian voice — Hinglish for WhatsApp/Insta, Devanagari for SEO, English for LinkedIn / Tier-1 metros
⚠ Picking the right Udyam category (Micro / Small / Medium) without consulting a CA — turnover + investment thresholds shift each Union Budget

AI Central Tools solves all of that — for free.

Frequently Asked Questions

How does the GSTIN modulo-36 validation work?
We implement the GSTN reference algorithm locally — base-36 alphabet "0123456789A-Z", weights alternating 1,2 from the leftmost data character, sum the digit-sums in base 36, and compute check_digit = (36 - sum%36) % 36. The 15th character of the GSTIN must match this. The algorithm catches ~97 % of common typos (single-digit swaps, O/0 confusions, etc.) before the IRP rejects them.
Why don't you call the GSTN public taxpayer search directly?
The GSTN public search at https://services.gst.gov.in/services/searchtp requires CAPTCHA so it cannot be auto-called. The validator returns the canonical lookup URL alongside the structural verdict so you can confirm registration status manually. For programmatic active-status checks, the GSTN B2B API is available to GSPs and ASPs only.
Is e-invoicing mandatory for my Indian business?
As of FY 2025-26, e-invoicing is mandatory for B2B / SEZ supplies of taxpayers whose aggregate turnover exceeds ₹5 Cr in any preceding financial year (CBIC notification 10/2023 and subsequent amendments). B2C invoices are exempted from IRN but must carry a self-generated dynamic QR code. Below the threshold, e-invoicing is optional but recommended.
Why do you ship Devanagari in addition to Hinglish?
Hinglish is informal and Roman-only — Google's hi-IN search index is a Devanagari index. To capture both the WhatsApp/Instagram audience (Hinglish) AND the search-traffic audience (Devanagari), you publish both in parallel. The English baseline serves Tier-1 metro readers and the Indian diaspora.
