The problem

Running the business is your job.
Running its finances became one too.

Indian SME owners are part-time accountants by force — and everyone pays for it.

The compliance treadmill

GST returns, TDS deposits, advance-tax instalments, ITR, ROC filings — every month brings a new deadline, and every missed one brings interest and penalty.

हर महीने एक नई deadline।

The shoebox handoff

At year-end the CA receives a pile of bank statements, bills and half-entered books — then spends billable weeks reconstructing what happened instead of advising.

CA को मिलता है कच्चा-पक्का हिसाब।

Money left on the table

Regime choice, presumptive elections, deductions, depreciation timing, partner remuneration — legal tax-saving options expire quietly because nobody ran the numbers in time.

बचत के मौके चुपचाप निकल जाते हैं।
What Sarthi is

Seven roles. One engine. Every entity.

For each business you add — proprietorship, partnership, company or trust — Sarthi works the whole finance desk.

01

AI CFO

Schedule III P&L, Balance Sheet and Cash Flow from double-entry books that always reconcile — plus a portfolio dashboard across all your entities.

02

AI CA

Income-tax computation tailored to your legal structure — slabs, 87A rebate, surcharge with marginal relief, presumptive schemes, firm and company provisions.

03

AI Internal Auditor

Benford's Law screening, duplicate payments, cash-transaction red flags, GST return cross-checks, TDS deposit gaps — ranked findings, each flagged for CA review where needed.

04

AI Compliance Engine

An auto-built statutory calendar — GST, TDS, advance tax, ITR, tax audit, ROC — with penalty and interest calculators so you know exactly what a delay costs.

05

AI Tax Strategist

Legal tax-saving strategies as action cards: rupee impact, the section it relies on, the deadline, the risk level — plus a what-if simulator for big decisions.

06

AI Risk Engine

Risk scores, runway, a 13-week cash forecast, and idle-cash detection with after-tax, risk-tiered deployment options for surplus funds.

07

AI Business Optimiser

Working-capital opportunities, ratio and liquidity analysis, and plain-English narration of what the numbers mean and what to do next.

How it works

From raw books to a CA-ready pack, in four steps

1

Import your books

Bring in bank statements and books. Sarthi posts them into a proper double-entry ledger where debits always equal credits.

2

Statements + tax, built

Sarthi produces Schedule III financial statements and a full income-tax computation for your entity type — deterministic, rule-driven, FY-versioned.

3

Findings + strategies

Audit findings and legal tax-saving strategies arrive ranked — every one citing the section it relies on, with rupee impact and deadline.

4

One-click CA pack

Export a fully cross-referenced hand-off pack — Excel, PDF, JSON and print-ready HTML — that your CA reviews and signs.

No invented numbers: every rate and limit comes from a versioned knowledge base, tagged with its section and applicable financial year. हर आँकड़े के पीछे उसकी धारा।

Privacy first

Your books stay on your machine. Full stop.

Most tax portals ask you to upload your financial life to their cloud. Sarthi is built the other way around — local-first, by design.

  • AES-256 encrypted vaultYour entire dataset lives in one AES-256-GCM encrypted file on your own disk, locked by your passphrase.
  • Offline mode is the defaultThe deterministic rules engine needs no network at all. The optional AI layer is privacy-bounded — and entirely your choice.
  • No cloud upload, everThere is no Sarthi server holding your books. Nothing to breach, nothing to subpoena, nothing to leak.
  • Tamper-evident audit logEvery change to your books is chained with SHA-256 hashes — any edit to history is detected and shown on the dashboard.

One vault. Your disk. Your key.

./data/sarthi.vault  ·  AES-256-GCM

आपका डेटा, आपके कंप्यूटर पर — कहीं और नहीं।

vs. cloud tax portals: they hold your data on their servers, under their terms. Sarthi holds nothing — because it never sees it.

Sarthi prepares; your CA signs. सारथी तैयार करता है, हस्ताक्षर आपके CA के।

Sarthi is a preparation and decision-support tool — not a substitute for a qualified Chartered Accountant. It does the heavy lifting so your CA's time goes into judgment, review and sign-off, not data entry.

Every tax and audit output cites its section, states its assumptions, and flags low-confidence items for CA review. Everything it suggests is strictly legal tax planning — never evasion.

Section-cited outputs Stated assumptions CA-review flags Legal planning only
