About Fastbooks
You run the business. Fastbooks prepares the accounts.
Fastbooks is AI-assisted, review-first accounting for Indian businesses. Bills, PDFs, bank activity, voice notes and typed instructions become structured, review-ready entries. The source stays visible. Uncertain details stay visible. Nothing changes your accounts until you approve it. Purchase, Sale, Receipt, Payment, Journal, GST, stock and reports all stay part of your normal workflow.

Behind Fastbooks
Nishant Sah
Proprietor, Fastbooks
Fastbooks is owned and operated by Nishant Sah as a sole proprietorship.
Positioning
Not a blind accounting replacement. A work-preparation layer.
Fastbooks is designed for business owners, accountants, GST practitioners and local operators who want less manual entry and cleaner review. It focuses on the work before final books: bill capture, bank-entry preparation, party/item hints, ledger suggestions and review-ready drafts.
- India-first small-business workflows.
- Review-first AI accounting drafts.
- Works alongside accountants and existing habits.
- Built for bills, bank rows, PDFs and voice-style inputs.
Why this exists
Most small businesses do not need more complexity.
They need to stop losing bills, chasing accountants for every small entry, and reconstructing bank/payment context at month end. Fastbooks is being built to make that first-mile accounting work simpler.
Trust stance
AI prepares. Humans approve.
Fastbooks should not promise automatic statutory correctness. The product direction is to prepare drafts and keep uncertain values visible so the owner, accountant or CA can approve, correct or reject.
