SA 230 working papers built for file review.

Audit documentation software for Indian CA firms that need an audit file index, reviewer trail, evidence links, assembly discipline, and retention-ready working papers.

SA 230 asks whether an experienced auditor with no previous connection to the engagement can understand the nature, timing and extent of procedures, the results, the evidence obtained, and the conclusions reached from the file alone. CORAA composes that file as the audit happens: every selection is seeded and printed, every procedure is timestamped, every review note is attributable, and every conclusion links back to the underlying evidence.

  • Audit file index mapped to planning, risk assessment, execution, completion, reporting, and communications
  • Selection seeds printed on every sample so re-performance returns the same set
  • Reviewer notes, preparer sign-offs, timestamps, and prior values retained against the working paper
  • Final file assembly and lock trail retained 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 may fail the SA 230 experienced-auditor test.

On the Ledger

  • Every working paper carries an index reference, preparer/reviewer trail, seed, and evidence link
  • Reviewers see the current state plus the full edit history side by side
  • Cross-references between TB, lead, group, sample, finding, and report resolve automatically
  • Every change records reviewer, timestamp, prior value, and reason where required
  • A peer-review or NFRA-style re-performance returns the same numbers from the same inputs
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 mapped ledger data

Every working paper is filed against a canonical audit file index. Planning, risk assessment, controls, substantive testing, completion, reporting, communication, and closure records sit in predictable sections. Lead schedules tie to financial statement captions, group schedules to leads, and sample schedules to groups.

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. This supports SA 230's sufficient-detail discipline and makes SA 530 sample selection re-performable.

Step 04

Step 4, Edit log per working paper

Every change to a working paper, manual override, threshold tweak, conclusion update, or review clearance captures who changed it, when it changed, and what value it replaced. Reviewer notes attach inline and remain visible in the final file.

Step 05

Step 5, Assemble and lock the file

The final file assembly record shows what was included, when assembly was completed, and what changed after assembly. Reproducible exports stay available for peer review, NFRA inspection, firm monitoring, or successor auditor inquiry under SA 510.

Inside the module

What you actually get.

Audit file index

Every working paper has a stable index reference for planning, risk assessment, fieldwork, completion, reporting and communications. The same lead schedule carries the same identifier across years.

  • ›Acceptance, independence and planning papers
  • ›Risk assessment, materiality and sampling papers
  • ›Lead schedules, group schedules and sample schedules
  • ›Completion, reporting and communication papers

Reviewer overlay

Partners and managers see the audit team's current version, review notes, clearance status and prior reviewer annotations side by side. The review trail does not disappear when a note is marked resolved.

  • ›Prepared by and reviewed by fields
  • ›Date and time of performance and review
  • ›Open, cleared and reopened review notes
  • ›Reason trail for post-review changes

Reproducible exports

Any working paper can be re-exported from the Engagement Log on demand. The export includes the source population, selection method, seed, procedure, result, exception handling and conclusion exactly as retained.

Assembly and retention controls

The module supports the SA 230 file assembly discipline and the Indian seven-year retention floor by keeping the final file accessible, readable and protected from silent deletion or undocumented change.

  • ›Final assembly checklist
  • ›File lock and post-assembly change trail
  • ›Retention-ready export archive
  • ›Access log for sensitive working papers

Successor-auditor pack

Generate a SA 510-aligned handoff package for incoming auditors. It includes the opening-balance verification trail, prior-year significant matters, unresolved findings and outstanding follow-ups.

AI-use documentation

When AI assists with drafting, classification or exception summarisation, the file can retain the tool use, prompt or instruction class, source data, human review and final auditor conclusion.

Frequently asked

Answers, up front.

SA 230 audit documentation is the record of audit procedures performed, evidence obtained, significant matters, review, and conclusions reached. The practical test is whether an experienced auditor with no previous connection to the engagement can understand the work from the file alone.
A practical SA 230 audit file index should cover engagement acceptance, independence, planning, risk assessment, materiality, sampling, controls, substantive procedures, lead schedules, exceptions, completion, reporting, written representations, communications and file assembly. CORAA keeps these sections linked to the underlying evidence instead of leaving them as disconnected folders.
SA 230 expects the final audit file to be assembled on a timely basis, ordinarily not more than 60 days after the date of the auditor's report. That period is for administrative assembly, cross-referencing and completion checks. It is not a period for performing new audit procedures or reconstructing work after signing.
ICAI amended the SA 230 documentation retention period to seven years, aligned with SQC 1. Treat seven years as the floor: firm policy, litigation, NFRA inspection, peer review, contractual terms or sector-specific rules can justify retaining a file longer.
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, the seed and the resulting list. A reviewer with the same seed and the same population gets the same 47 entries. That makes re-performance possible.
NFRA and peer reviewers inspect the file, not the team's memory. CORAA helps by preserving what was tested, which population was used, how samples were selected, what evidence supported the conclusion, who reviewed the work, and what changed after review or assembly.
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.
A SA 510-aligned package generated with one click: the opening-balance verification trail, prior-year significant matters, and outstanding follow-ups — built for an incoming auditor to pick up the engagement without reconstructing context from scratch.
Yes. CORAA keeps the product workflow live in the Engagement Log and also supports exportable working papers. For a standalone starting point, use the site's Audit File Index — SA 230 Documentation Structure template in the templates library.
No. AI-written text is only useful when it accurately reflects work actually performed and links to evidence. The file still needs source data, procedure details, results, exceptions, review and auditor conclusion. CORAA treats AI as assisted drafting over evidence, not as a replacement for audit judgment.
