SA 510 requires the ऑडिटर to obtain sufficient appropriate ऑडिट साक्ष्य that ओपनिंग बैलेंस do not contain misstatements that materially affect the current period's वित्तीय विवरण. CORAA implements this by ingesting the prior-वर्ष signed ऑडिट रिपोर्ट (PDF) or the prior-वर्ष ट्रायल balance (Excel), and tying every current-वर्ष opening figure to its prior-वर्ष closing counterpart. Drift surfaces before fieldwork begins.
Two paths to the same audit conclusion. One leaves traces; the other doesn't.
At एंगेजमेंट सेटअप, upload the prior-वर्ष signed ऑडिट रिपोर्ट PDF. CORAA extracts the closing balances per लेजर via OCR. Alternative: upload the prior-वर्ष ट्रायल Balance as Excel for direct ingestion.
After current-वर्ष डेटा ingests, CORAA runs the SA 510 verification: each CY opening figure matched to its PY closing counterpart. Variances above the configured threshold surface in the SA 510 Working Paper.
For each variance, the ऑडिटर either (a) accepts with documented rationale (e.g., reclassification between लेजर), (b) flags for क्लाइंट correction, or (c) discloses in Form 3CD or the ऑडिट रिपोर्ट. The SA 510 Working Paper is locked when सभी variances are addressed.
Upload the signed PY ऑडिट रिपोर्ट as PDF. CORAA's OCR extracts the closing balance per लेजर from the Schedule III BS and P&L. Works on Indian ऑडिट रिपोर्ट formats from any ऑडिट फ़र्म.
When no PY ऑडिट रिपोर्ट is उपलब्ध (or to supplement it), upload the PY ट्रायल Balance as Excel. CORAA matches लेजर between PY and CY by GL Code first, then by name.
The SA 510 Working Paper lists every लेजर with PY closing, CY opening, and variance. Variances above threshold are highlighted; zero-variance लेजर can be collapsed.
When no PY ऑडिटर existed (नया entity, change of ऑडिटर), SA 510 first-वर्ष प्रक्रियाएँ apply. CORAA prompts for: management representation, physical asset verification, balance confirmations from third parties, and समीक्षा of PY books if उपलब्ध.
