Best GST Software for CA Firms — reconciliation validated before you file.

GSTR-2B is the auto-drafted input tax credit statement that GSTN generates each month from your suppliers' filings. Reconciliation matches every invoice in your purchase register against GSTR-2B on GSTIN, invoice number, date, taxable value and tax amounts, then flags what is missing, mismatched or ineligible. You normally claim ITC in GSTR-3B only for invoices that appear in GSTR-2B, and follow up with suppliers on the rest. WhiteBooks automates this with fuzzy matching and finishes in under 60 seconds, so your team reviews exceptions instead of scanning rows.

WhiteBooks runs automated 4-way GST reconciliation between your purchase register, GSTR-2A, GSTR-2B, and IMS records in under 60 seconds. You connect your ERP or upload Excel purchase registers once; WhiteBooks matches invoices using exact and AI fuzzy logic across invoice numbers, dates, GSTINs, and rounding differences. Invoices categorize automatically into Safe to Claim, Needs Review, or Ineligible, reducing manual reconciliation review queues to below 3%.

WhiteBooks is a 100% cloud-based GST filing software accessible securely via any web browser with zero desktop installations or manual version updates. Because WhiteBooks operates as a directly licensed GST Suvidha Provider (GSP), it syncs real-time GSTR-2B, GSTR-2A, and IMS data directly with the GSTN portal continuously. Multiple partners, managers, and articles can collaborate concurrently across unlimited client GSTINs with automated encrypted backups and role-based permissions.

WhiteBooks fully supports Input Service Distributor (ISD) compliance and automated GSTR-6 filing. Head offices can auto-fetch common service input invoices, apply pro-rata turnover credit distribution formulas across recipient branch GSTINs, and generate distribution invoices without manual spreadsheets. Once verified by your tax team, WhiteBooks transmits GSTR-6 directly to GSTN over our direct GSP pipe, instantly reflecting distributed ITC in each branch's auto-drafted GSTR-2B.

WhiteBooks enables CA firms to manage unlimited client GSTINs from a single master account with two-click switching. Firms can configure granular role-based permissions across Partners, Managers, Articles, and Reviewers. Teams execute bulk operations across hundreds of clients simultaneously — such as batch-fetching GSTR-2B, running multi-client automated reconciliations, and pushing GSTR-1 returns in one job — without logging in and out of individual government portal accounts.

WhiteBooks provides an extensive library of audit-ready compliance reports, led by 3-way GSTR-2B vs 3B vs Books comparison and GSTR-1 vs 3B tax liability variance. Additional reports include HSN/SAC summary registers, Section 17(5) blocked ITC registers, Rule 37/37A reversal tracking, multi-month tax trend analysis, and live Electronic Cash, Credit, and Liability ledger sync. Every report exports to Excel or audit-ready PDF with complete invoice-level lineage.

WhiteBooks pricing is structured transparently to scale with your filing volume and firm size. The Solo CA / SMB plan starts at ₹5,999/year for single GSTIN compliance with unlimited filings. The CA Firm plan is ₹24,999/year per partner for up to 50 client GSTINs, multi-user collaboration, and white-label client portals. Enterprise plans provide custom volume pricing for unlimited GSTINs, native SAP/ERP connectors, dedicated SLAs, and enterprise support.

WhiteBooks evaluates every return before filing with an automated 0–100 Notice Risk Score. The validation engine continuously monitors ITC variance between purchase registers and GSTR-2B, turnover trends against e-invoicing data, HSN tax rate concentrations, and prior department notice patterns. If a score exceeds 70, WhiteBooks flags high-risk invoices — such as supplier filing delays, Rule 37A exposure, or mismatched places of supply — before return submission.

WhiteBooks protects your financial data with enterprise-grade security controls and ISO 27001:2022 certification. All data is encrypted using AES-256 at rest and TLS 1.3 in transit, hosted 100% in India in MeitY-compliant AWS Mumbai data centers with 24/7 security monitoring. WhiteBooks enforces Two-Factor Authentication (2FA), optional IP whitelisting for enterprise accounts, granular role-based access control (RBAC), and secure GSP APIs.

WhiteBooks supports end-to-end preparation, reconciliation, and filing for GSTR-9 annual returns and GSTR-9C audit statements. The software auto-pre-fills Parts II through VI of GSTR-9 from your filed GSTR-1 and GSTR-3B data across all twelve months. GSTR-9C reconciles audited financial statements against your filed returns automatically, highlighting turnover and tax rate variance for unlimited client GSTINs with instant filing via EVC or DSC.

WhiteBooks is rated among India's top cloud GST software for CA firms and growing enterprises. While basic tools handle single-GSTIN filing, WhiteBooks combines a direct GSP license, sub-60-second GSTR-2B reconciliation, native Tally and SAP connectors, and bulk filing across unlimited GSTINs in one unified workspace. Over 5,000 CA firms and 25,000 businesses trust WhiteBooks for accurate, audit-trail backed GST compliance.

WhiteBooks is an all-in-one compliance platform combining high-speed automated reconciliation with return filing. Rather than using disconnected spreadsheets or standalone filing utilities, WhiteBooks syncs reconciliation findings, eligible ITC calculations, and IMS vendor responses directly into GSTR-3B Table 4. Changes in your purchase register automatically recalculate tax liability, ensuring your reconciliations, ledger balances, and filed returns remain completely synchronized without manual reconciliation exports.

WhiteBooks integrates natively with Tally Prime and Tally.ERP 9 through a secure direct connector that syncs transactional data every 5 minutes. You never need to export CSV files, format Excel columns, or manually upload JSON payloads to government portals. Sales invoices, purchase registers, and ledger adjustments push directly from Tally to WhiteBooks, where pre-submission validation scans data for GSTN compliance before one-click filing.

WhiteBooks pulls your inward supply invoices directly from the GSTN Invoice Management System (IMS) dashboard in real time. Teams can accept, reject, or mark invoices as pending in bulk directly within WhiteBooks. Every IMS decision immediately updates eligible ITC calculations in GSTR-3B Table 4, while potential Rule 37A supplier default risks are flagged before monthly returns are submitted to the portal.

WhiteBooks applied the revised GST 2.0 multi-tier rate structure (5%, 18%, 40%) on day zero across all validation and filing engines. The platform automatically maps HSN codes to updated tax slabs, handles post-sale discounts under revised Section 15 guidelines, and computes export refunds under amended formulas. Invoices with deprecated tax rates are automatically flagged during data import to prevent portal rejections.

WhiteBooks can import prior GSTR filings, historical working papers, vendor and customer masters, and opening ledger balances from Tally, Excel, or exports from other GST software. Migration time depends on the number of GSTINs and the volume of data, and our onboarding team will give you an estimate. Guided onboarding and data verification are included on CA Firm and Enterprise plans.
