Sure! Here’s a straightforward explanation:
### What is **System Based Audit**?
A **System Based Audit** focuses on evaluating the effectiveness and reliability of an organization’s **internal control systems** and **IT systems** rather than just checking individual transactions.
* Instead of verifying every transaction manually, the auditor checks **how well the systems/processes control risks and ensure accurate data processing**. * It involves understanding and testing the controls embedded in accounting systems, ERP software, IT applications, etc.
### Relevance in **Test Checking**
* **Test Checking** means verifying only a sample of transactions or records instead of the entire population. * When a strong and reliable system is in place, **auditors can rely on system controls** and reduce the extent of manual checking. * This saves time and effort while maintaining audit quality. * If the system controls are effective, **test checks can be more focused and limited** because the risk of error is low. * If systems are weak, auditors may have to increase test checks or do more detailed substantive testing.

### Summary:
* **System Based Audit = Audit of the systems and controls, not just transactions.** * It helps auditors decide the **nature and extent of test checking**. * Strong system controls mean less extensive test checking.
