Why we built TatvaBooks
Two decades of audits, GSTR-1 cycles and late-night reconciliations later, the Indian cloud accounting software we wished for didn't exist. So we built it.
Author profile
CA Anil Agarwal
Veteran Chartered Accountant. Co-founder of Tatva Fintech. Two decades of practice across audit, GST and indirect tax.
About
Anil is a Chartered Accountant in practice for over two decades. Across audit, GST and indirect tax, he has worked with everything from sole-proprietor traders to mid-sized manufacturing firms — and watched the Indian compliance landscape change from VAT-era paper returns to today's GSTN-integrated, IRP-stamped, AIS- aggregated regime.
His view on accounting software has been shaped by sitting on both sides of the table. As an auditor, he's seen the cost of bad books: GSTR-1 reconciliations that take three days, ITC that quietly lapses on Section 16(4), B2B invoices missing IRNs that buyers find out about on their 2B. As a CA in practice, he's watched articles spend hours fixing problems that shouldn't have been allowed to enter the books in the first place.
That conviction — that accounting software should refuse the wrong post, not catch it three days later — is the founding idea behind TatvaBooks.
What he writes about
Anil writes primarily for working CAs and the SMBs they serve. His pieces sit in two of the three TatvaBooks blog series:
- Working CA — operational pieces on how a monthly close should run, what the systematic causes of a GSTR-2B mismatch are, and where article time gets eaten.
- GST Live — notes from the ground on regulatory changes that matter to working practitioners — e-Invoice thresholds, ISD mandates, Section 128A amnesty.

On the product
Anil contributes the audit and indirect-tax discipline that shapes TatvaBooks's posting layer. The sale voucher validation — the screen that refuses to post a CGST+SGST sale to an interstate customer — is a direct expression of his view that the product should make wrong entries impossible at the point of entry. The audit trail discipline (immutable posted vouchers, paired cancellations, dated period locks) is the same.
