CA Firms: Multi-Client GST Compliance

25,000+ CAs and tax professionals file GST returns through WhiteBooks. The multi-client dashboard tracks 50–500 client GSTINs, shows deadlines, surfaces filing exceptions, and runs bulk reconciliation against GSTR-2B in minutes instead of days.

Multi-client dashboard

API for large practices

Firms with 500+ clients integrate WhiteBooks via API into their practice-management system. The GST API exposes the same surface used by the dashboard — multi-GSTIN, deadline data, GSTR-2B fetch, return filing — so you can build custom dashboards.

Client-facing portal

Each client can be given limited access to their own dashboard — see their filing status, download their GSTR-2B reconciliation, approve / reject return drafts before the CA files. Reduces the back-and-forth email / WhatsApp volume materially.

FAQs

Who uses WhiteBooks for Professional Services workflows?

CAs and tax consultants manage 50–500 clients with overlapping GST deadlines. Manually logging into 50 GSTN portals isn't viable. WhiteBooks handles this via OAuth 2.0 REST APIs, first-party SDKs in Java / Node / Python, and pre-built connectors for SAP / Oracle / Dynamics / Tally.

How long does integration take?

Typical timelines: 1–2 sprints for SaaS / fintech integrations on the raw REST API; 3–5 weeks for Tally-connector deployments; 4–8 weeks for SAP / Oracle full integrations.

Sandbox?

Yes — apisandbox.whitebooks.in/{product} mirrors the production schema with a sample GSTIN. Free.

Does it support KSA ZATCA?

Yes — WhiteBooks ships a dedicated KSA e-Invoice API for businesses with Saudi Arabia operations. See /api/ksa-e-invoice-api-for-developers.

Pricing?

Annual plans from Custom pricing (Starter, 1,000 IRN/month) → Custom enterprise pricing/year (Enterprise, unlimited). Free sandbox. See /about/pricing.
