Working papers anyone can re-perform.

Documentation that meets the experienced-auditor test by default.

SA 230 demands that an experienced auditor with no prior knowledge of the engagement can understand the procedures, evidence, and conclusions from the working papers alone. CORAA composes that file as the audit happens, every selection seeded and printed, every procedure timestamped, every conclusion linked back to the underlying evidence.

  • Every working paper auto-indexed with a permanent reference
  • Selection seeds printed on every sample so re-performance returns the same set
  • Edits captured with reviewer, timestamp, and the prior value
  • Final file locked after UDIN, immutable in the Engagement Log
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

  • -Folders of Excels and PDFs with inconsistent naming
  • -Reviewer cannot tell which version of a working paper supports the opinion
  • -Cross-references typed by hand, often broken by the time the file ships
  • -No record of what was changed, by whom, or why
  • -If NFRA or peer review pulls the file, days are spent reconstructing the trail
An audit file that cannot be re-performed is, by SA 230 definition, not documented at all.
CORAA

On the Ledger

  • Every working paper carries an index reference, the seed, and the evidence link
  • Reviewers see the current state plus the full edit history side by side
  • Cross-references between TB, lead, group, and sample resolve automatically
  • Every change records reviewer, timestamp, and the value it replaced
  • An NFRA-style re-performance returns the same numbers from the same inputs, every time
The file meets the experienced-auditor test before the partner opens it.
How it works

Three steps. Every trace logged.

Step 01

Step 1, Index from the Universal Audit Ledger

Every working paper is filed against a canonical index, A through Z plus 1 through 99. Lead schedules tie to financial statement captions, group schedules to leads, sample schedules to groups. The index is generated, not typed.

Step 02

Step 2, Timestamped evidence link

Each conclusion is anchored to the voucher, ledger entry, GST return row, 26AS row, or external confirmation that supports it. Click any conclusion in the working paper and the underlying evidence opens with its capture timestamp and source.

Step 03

Step 3, Seed-printed selection

Every sample selection prints the formula, the seed, and the resulting items. Anyone re-performing the audit with the same seed gets the same items. Required by SA 230's 'sufficient detail' clause and SA 530's reproducibility.

Step 04

Step 4, Edit log per working paper

Every change to a working paper, manual override, threshold tweak, conclusion update, captures who, when, and the prior value. Reviewer notes attach inline. Edits remain visible in the final file.

Step 05

Step 5, Lock at UDIN, immutable in Engagement Log

Once UDIN is issued the file moves to the Engagement Log and cannot be modified. Reproducible exports are available indefinitely, ready for NFRA inspection, peer review, or successor auditor inquiry under SA 510.

Inside the module

What you actually get.

Permanent index

Every working paper has a stable index reference that does not change across years. The same lead schedule carries the same identifier, audit after audit.

Reviewer overlay

Partners see the audit team's current version and the prior reviewer's annotations side by side. No more reconciling redlined PDFs.

Reproducible exports

Any working paper can be re-exported from the Engagement Log on demand. The export includes the seed, the inputs, the procedures, and the conclusion, exactly as it stood at UDIN.

Frequently asked

Answers, up front.

No. SA 230 is about evidence, indexing, and reproducibility, not template wording. Firms continue to use their own engagement letter, planning memo, and reporting templates. CORAA generates the evidence-bound working papers that sit inside that framework.
When the audit selects, for example, 47 journal entries for SA 240 testing from a population of 12,000, the working paper records the selection method (random, stratified, MUS), the seed (a number, typically a SHA-256 hash of engagement and procedure metadata), and the resulting list. A reviewer with the same seed and the same population gets the same 47 entries. NFRA's 2023 inspection findings specifically flagged audits where selection could not be reproduced.
The Engagement Log retains immutable working papers for the period required by your jurisdiction. In India, the ICAI's Standards on Quality Management require seven years from the audit report date. CORAA retains them for ten by default, configurable in the engagement settings.
Captured inline against the working paper they refer to. Comments are timestamped and attributed. Resolved comments remain visible in the audit trail; they are not deleted.
Clients see the findings their engagement raises and any open queries directed at them. The working paper file itself, and the audit trail behind it, is the firm's property and the firm controls access.
