Tier I / II / III progression

The audit progresses as evidence arrives. Tier I starts every engagement.

Tier I, Tier II, Tier III audit progression

Auditees rarely have all evidence ready on day one. CORAA acknowledges this by structuring the engagement as three evidence tiers. Tier I begins every audit with just the General Ledger, Trial Balance, and Chart of Accounts. Tier II adds the Party Master and prior-year audit report. Tier III adds the Bill Register and Fixed Asset Register. Each tier unlocks more working papers without forcing the audit to wait.

  • Tier I (Books-only): 14 working papers unlocked from books alone
  • Tier II (Evidence-anchored): party-wise ageing, MSMED Act bifurcation, Related Party Transactions
  • Tier III (Audit Judgement): Sec 32 depreciation, PPE roll-forward, bill-wise ageing, KAM for listed entities
  • CORAA flags exactly what evidence is missing when a higher-tier deliverable needs it
  • The auditor never waits, work begins with what the client provides today
Two paths, one ledger

The old way, and ours.

Two paths to the same audit conclusion. One leaves traces; the other doesn't.

Traditional

The old way

  • -Audit team waits for all evidence before starting fieldwork
  • -Two to three weeks lost while client gathers FA register, party master, prior-year report
  • -When evidence finally arrives, audit team rushes through testing
  • -Documentation suffers because everything happens at once
Time-to-fieldwork: typically 2-3 weeks after engagement letter. Quality drops under deadline pressure.
CORAA

On the Ledger

  • Audit begins on day one with Tier I evidence
  • Tier II unlocks party-level work when Party Master arrives
  • Tier III unlocks Bill Register and FA Register work when those arrive
  • Engagement Overview shows exactly which working papers are locked, unlocked, or pending
  • Sign-off blockers surface only when evidence for that specific blocker is missing
Time-to-first-Working-Paper: typically 1-2 hours after engagement letter. Quality preserved across the audit.
How it works

Three steps. Every trace logged.

Step 01

Begin at Tier I

Upload General Ledger, Trial Balance, and Chart of Accounts. CORAA unlocks 14 working papers immediately: Ledger Scrutiny, Schedule III BS / P&L / Cash Flow, Form 3CD Tier-I clauses, books-only GST / TDS / TCS checks, Materiality memo, Sampling.

Step 02

Advance to Tier II

Add Party Master with PAN, GSTIN, and MSME flags. Add prior-year audit report. CORAA unlocks AR/AP party-wise ageing (Note 21 + Note 8), MSMED Act bifurcation, Related Party Transactions per SA 550, Opening Balance Verification per SA 510.

Step 03

Advance to Tier III

Add Bill Register and Fixed Asset Register. Lock Materiality memo. Lock Sampling plan. CORAA unlocks PPE roll-forward per Schedule II, Form 3CD Clause 18 Sec 32 depreciation, bill-wise ageing, KAM for listed entities per SA 701, Opinion & Report seven-step UDIN sign-off.

Inside the module

What you actually get.

Tier I, the universal baseline

Every audit starts here. Three files cover it: GL with every voucher, TB with opening and closing per ledger, CoA with group hierarchy.

  • ›General Ledger: every voucher line
  • ›Trial Balance: opening, period movement, closing
  • ›Chart of Accounts: parent group, sub-group, ledger hierarchy
  • ›Unlocks 14 working papers immediately

Tier II, evidence-anchored

Once the Party Master is uploaded with PAN, GSTIN, and MSME flags, CORAA can do party-wise work that books alone cannot deliver.

  • ›Trade Payables MSME bifurcation (Note 23)
  • ›Party-wise AR/AP ageing
  • ›Related Party Transactions per SA 550
  • ›Sec 40A(2)(b) related-party payments (Form 3CD Clause 23)
  • ›Form 3CD Clause 44 GST-wise expense break-up
  • ›SA 510 Opening Balance Verification

Tier III, audit judgement

With the Fixed Asset Register and Bill Register loaded and materiality plus sampling locked, the audit reaches its final form.

  • ›PPE roll-forward by asset class (Note 11)
  • ›Capital Work-in-Progress ageing (Note 12)
  • ›Form 3CD Clause 18 Sec 32 depreciation
  • ›Bill-wise AR/AP ageing
  • ›Form 3CD Clause 17 Sec 50C property transfers
  • ›KAM identification for listed entities per SA 701

Engagement Overview

The Overview screen shows three columns side by side: Tier I unlocked items, Tier II evidence-anchored items, Tier III audit-judgement items. Each item is marked complete, in progress, or locked.

  • ›Visual progression across three tiers
  • ›Locked items show which evidence is missing
  • ›Auditor can request specific files from client with one click
Frequently asked

Answers, up front.

Indian audit clients deliver evidence in batches. Demanding everything before starting fieldwork delays the audit by two to three weeks while the client gathers prior-year reports and registers. Tiered progression starts the audit immediately with what is available and unlocks more as evidence arrives.
Fourteen working papers unlock from books alone: Trial Balance, Schedule III BS, P&L, Cash Flow, CARO Rule 11(e) ratios, Ledger Classification, Ledger Scrutiny, Transactional Scrutiny, Form 3CD entity clauses, Form 3CD Clause 11 books, Clause 21 disallowable expenses, Clause 26 Sec 43B, Clause 34 books-only TDS/TCS sectional totals, Materiality memo, Per-Working-Paper Sampling.
Tier III for any engagement requiring CARO 2020 reporting (most companies). Tier II for tiny entities exempt from CARO. Below Tier II, the auditor cannot complete the seven sign-off blockers required before UDIN issuance.
