## Timely Preparation vs. Assembly of Final Audit File
Two related but distinct timing requirements govern audit documentation:
---
### 1. Timely Preparation (SA 230)
- The auditor must prepare audit documentation on a timely basis — during or immediately after the audit work is performed.
- Documentation prepared after the audit is inherently less accurate than documentation prepared at the time the work is performed.
- Timely documentation enhances audit quality and facilitates effective review of evidence and conclusions before the audit report is finalised.
---
### 2. Assembly of the Final Audit File (SQC 1)
- After the audit report is issued, the auditor must assemble the final audit file.
- Time limit: ordinarily not more than 60 days after the date of the auditor's report.
- This is an administrative process only — it does NOT involve performing new audit procedures or drawing new conclusions.
- Changes made during the assembly process must be administrative in nature only.
> Critical distinction: "Timely preparation" (SA 230) = documentation done during the audit. "Assembly of final file" (SQC 1) = administrative compilation up to 60 days after the report date. These are two separate, non-interchangeable requirements.

### 3. Retention of Audit Documentation (SQC 1)
- Retention period: ordinarily not shorter than 7 years from the date of the auditor's report — or, if later, the date of the group auditor's report.
- Firms must establish policies and procedures for retention of engagement documentation.
---
### 4. Format of Audit Documentation
- Audit documentation may be recorded on paper or electronic or other media.
- An audit file is one or more folders or storage media in physical or electronic form.
- There is no mandatory requirement for paper format.
---
### 5. What NOT to Include in the Audit File
The auditor need not include:
- Superseded drafts of working papers and financial statements
- Notes reflecting incomplete or preliminary thinking
- Previous copies of documents corrected for typographical or other errors
- Duplicates of documents
