Security is not just a feature—it's our foundation. WhiteBooks follows a security-first approach with regular audits, vulnerability assessments, and continuous improvements.

The problem

GST compliance wasn't designed for AI. We're rebuilding it so it is.

The gap was never your data. It's software that can't reason about it.

Indian compliance changed more in 2025 than in the previous five years combined. GST 2.0 collapsed five slabs into three. E-invoicing thresholds dropped to ₹5 crore AATO. IMS went live. Rule 37A tightened ITC. The 30-day IRN window arrived. Your software hasn't kept up.

Most GST tools still treat compliance as data entry. WhiteBooks treats it as an inference problem — match invoices, flag anomalies, predict notices, and file in one keystroke. Built on the only thing that should be doing this work: AI plus a GSP license direct from GSTN.

sap_s4hana · sap_ecc

SAP-native integration

Push invoices from SAP S/4HANA or ECC to GSTN in real time. Generate IRNs and e-way bills inside the SAP transaction. No middleware, no separate ETL, no CSV fallbacks.

6,000 inv/min · Rule 37A

ITC optimization, not just matching

Match 6,000+ invoices per minute against GSTR-2B. Surface every blocked credit, every Rule 37A risk, every vendor with a falling compliance score — before you file 3B.

aato_threshold · 30d_window

AATO-aware automation

WhiteBooks reads your AATO and applies the right e-invoicing threshold, the right 30-day IRN window, the right ISD rule. The software adapts to the law, not the other way around.

The only India compliance API written like a modern API should be.

REST, idempotent, retryable. Sandbox keys in 5 minutes. Production-grade SLAs. Direct GSTN-licensed pipe — no resold APIs.

AI that reconciles, predicts, and explains — not just a chatbot in the corner.

WhiteBooks uses purpose-built models for four jobs that humans have been doing manually since GST launched in 2017.

reconcile01

Invoice matching at scale

Match your purchase register against GSTR-2B, including fuzzy vendor names, rounding deltas, and split invoices that exact-match logic can miss.

detect02

Anomaly detection before filing

Scan return data for common validation issues before submission, so your team can resolve exceptions before filing.

predict03

Notice prediction

WhiteBooks reads your filing pattern and flags returns likely to trigger a Section 61 scrutiny notice — based on ITC mismatch trends, turnover variance, and HSN distribution anomalies.

explain04

Copilot for compliance

Ask "Why did my ITC drop ₹4.2L in October?" or "Which vendors are unfiled for September?" — get an answer drawn from your live data, with source rows linked. Built on the Anthropic API.

Frequently asked Questions.

Signup to Explore the Features of WhiteBooks — A GST Software - A licensed GSP

Is WhiteBooks a licensed GSP or a reseller?+
WhiteBooks is a directly licensed GST Suvidha Provider (GSP) under GSTN. The license is held by BVM IT Consulting Services India Private Limited, the parent entity. No intermediary, no resold infrastructure.
How is WhiteBooks different from ClearTax, Tally, or Zoho Books?+
WhiteBooks holds its own GSP license — most competitors resell GSP capacity. WhiteBooks has native SAP S/4HANA and Tally connectors built in-house, not third-party.
Can I migrate from ClearTax TaxCloud to WhiteBooks?+
Yes. ClearTax discontinued TaxCloud access for many CA firms in late 2025. WhiteBooks runs a guided migration that imports all prior-year GSTR records, working papers, and client masters. Most firms migrate in under 45 minutes.
Does WhiteBooks support the new GST 2.0 rates (5%, 18%, 40%)?+
Yes. WhiteBooks applied the GST 2.0 rate structure from September 22, 2025, in line with the 56th GST Council notifications. HSN-level rate mapping, post-sale discount handling (revised Section 15), and the new refund mechanisms are all live.
Is e-invoicing mandatory for my business?+
From 1st April 2026, e-invoicing is mandatory for any business with AATO above ₹5 crore in FY 2025–26. For businesses above ₹10 crore AATO, invoices must be reported to the IRP within 30 days of the invoice date — invoices reported later are invalid for ITC. WhiteBooks enforces this window automatically.
Where is my data stored?+
WhiteBooks applies technical and operational safeguards to protect customer data. Contact our team to request the current security documentation for your review.
Do you have a free trial?+
Yes — 14 days, full features, no card required. CA firms get an extended 30-day trial including white-glove migration support.
What's the typical onboarding time?+
Self-serve SMB: same day. CA firm with up to 100 clients: 1–2 days. Enterprise with SAP integration: 2–4 weeks including UAT.
