You are the compliance manager at a Singapore-based financial institution. Your CFO just forwarded an email from the Monetary Authority of Singapore. The subject line: “Notice of Inspection.” Your stomach drops. You know your ERP system holds the transactional records, the audit trails, and the financial data that MAS will scrutinise. But do you know, with certainty, that your ERP can survive that audit?
This is not a hypothetical scenario. In 2026, MAS continues to intensify its supervisory focus on technology risk management, anti-money laundering controls, and data governance. For regulated firms in Singapore, the ERP system is no longer just a back-office tool. It is a compliance asset. Or a liability.
A MAS audit tests more than your financial data. It tests whether your ERP system can produce tamper-proof audit trails, enforce segregation of duties, and generate accurate regulatory reports on demand. This article covers the five critical compliance checks that examiners run, the common gaps found in Singapore firms, and a practical process to close them before the notice arrives.
The Five Compliance Checks That Matter Most to MAS
MAS examiners do not care about your ERP system’s user interface or how fast it processes a sales order. They care about control, integrity, and traceability. Based on our work with financial institutions in Singapore, here are the five areas where your ERP will face the hardest questions.
1. Audit Trail Completeness and Immutability
MAS expects every financial transaction to have a clear, unalterable record. That means your ERP must log who created, modified, or deleted a transaction, along with the exact timestamp and the previous value. If your system allows a user to edit a journal entry without leaving a trail, you have a problem.
Check if your ERP supports a “before and after” image for every data change. Some older systems only log that a change happened, not what the change was. That is not enough for a MAS audit.
2. Segregation of Duties (SoD)
A single employee should not be able to initiate, approve, and post a payment. MAS looks for SoD conflicts that could enable fraud or error. Your ERP must enforce role-based access controls that prevent one person from controlling an entire financial workflow.
For example, in a Singapore asset management firm, an accounts payable clerk should not also have the authority to approve vendor master changes. If your ERP allows users to hold multiple conflicting roles, the auditor will flag it.
3. Data Integrity and Accuracy
MAS will ask for proof that your financial data has not been tampered with. This goes beyond passwords. It includes database-level controls, encryption at rest, and checksums or hashing for critical records. If your ERP runs on a legacy on-premise system without database encryption, the risk of undetected data manipulation is higher.
4. Regulatory Reporting Capabilities
Your ERP must produce the reports that MAS requires, such as transaction monitoring reports, suspicious transaction reports (STRs), and periodic regulatory filings. If your team manually extracts data from the ERP into spreadsheets to build these reports, you introduce human error and version control risks. MAS expects automated, repeatable reporting workflows.
5. Access Control and User Activity Monitoring
Who has access to your ERP? Who accessed sensitive data last week? MAS will ask for a user access review report. Your system must log all login attempts, failed logins, and privileged user actions. If you cannot produce a report showing which users accessed the customer master data in the last month, your audit will stall.
A Practical Process for Running Your Own Pre-Audit Check
You do not need to wait for the MAS letter to arrive. You can run a self-assessment today. Here is a numbered process that takes most Singapore firms two to four weeks to complete.
-
Map your critical financial workflows. Identify the end-to-end processes that generate transactions subject to MAS oversight. Common examples include fund transfers, trade settlements, and fee calculations. Document each step and the system that supports it.
-
Review your audit trail configuration. For each critical workflow, verify that your ERP logs every create, read, update, and delete action. Test this by making a small change in a test environment and checking the audit log. If the log does not show the old value and the new value, you have a gap.
-
Run a segregation of duties conflict report. Most modern ERP systems have a built-in SoD report. Generate it. Look for any user who holds both an initiating role and an approving role for the same transaction type. Remediate any conflicts immediately.
-
Test your data integrity controls. Ask your IT team to confirm that your ERP database uses encryption and that critical tables have row-level checksums. If you are on a cloud ERP, request a SOC 2 report from your vendor to verify their controls.
-
Simulate a regulatory report request. Pick a report that MAS commonly asks for, such as a transaction listing for a specific date range. Generate it from your ERP without manual intervention. If you cannot produce the report in under 30 minutes, your reporting process needs automation.
Common Compliance Gaps Found in Singapore Firms
We have seen the same issues appear again and again during pre-audit assessments. Here is a table that maps the gap to the risk and the fix.
| Gap | Risk | Fix |
|---|---|---|
| Audit trail only shows “modified” without old and new values | MAS may deem records non-compliant with record-keeping requirements | Enable field-level auditing in your ERP configuration |
| Users share generic or shared logins | Impossible to attribute actions to a specific individual | Enforce unique user IDs and disable shared accounts |
| Regulatory reports are built in Excel with manual data pulls | High risk of data errors and version confusion | Implement a reporting module or BI tool that connects directly to the ERP database |
| No regular user access review process | Orphan accounts and excessive privileges go unnoticed | Schedule quarterly access reviews and automate the report generation |
| Database encryption is not enabled | Data at rest is vulnerable to unauthorised access | Enable Transparent Data Encryption (TDE) or equivalent |
Expert Advice on Preparing Your ERP for a MAS Audit
“The firms that pass MAS audits with the least stress are the ones that treat compliance as a system feature, not a manual add-on. If your ERP cannot produce a tamper-proof audit trail on day one, you are already behind. Do not wait for the notice to find out.” — Senior ERP Consultant, Temasys Enterprise Solutions
This advice reflects a reality we see often. Many Singapore firms invest in ERP systems for operational efficiency but neglect the compliance configuration. The result is a system that runs the business well but fails under regulatory scrutiny. The fix is not a new system. It is a compliance-focused configuration review.
How to Align Your ERP with MAS Technology Risk Management Guidelines
MAS has published the Technology Risk Management (TRM) Notice and the accompanying guidelines. These documents outline expectations for system resilience, security, and recovery. Your ERP must align with these requirements.
- System availability and disaster recovery. Your ERP should have a documented recovery time objective (RTO) and recovery point objective (RPO). MAS expects you to demonstrate that your ERP can be restored within the agreed time frame after a major incident.
- Change management. Any change to your ERP, whether a patch, upgrade, or configuration update, must follow a formal change management process. This includes testing, approval, and post-implementation review.
- Vendor management. If your ERP is cloud-based, MAS expects you to conduct due diligence on your vendor. You should review their certifications, data centre locations, and incident response track record.

What to Do If Your ERP Fails the Pre-Audit Check
Do not panic. Most gaps are fixable. Here are the three most common remediation paths.
- Configuration changes. Many ERP systems have compliance features that are not enabled by default. A configuration audit can turn on field-level auditing, enforce password policies, and set up segregation of duties rules.
- Process changes. Sometimes the system is fine, but the human process is the problem. For example, if your team shares login credentials, you can implement a policy that requires unique user IDs and provides training on the risks.
- System upgrade or migration. If your ERP is genuinely too old to support modern audit trail requirements, you may need to upgrade to a newer version or migrate to a cloud-based system. For guidance on this, see our legacy system migration guide for Singapore enterprises.
Building a Culture of Compliance Around Your ERP
Compliance is not a one-time project. It is a continuous practice. The firms that do best in MAS audits are the ones that embed compliance into their daily operations.
- Run quarterly access reviews.
- Test your disaster recovery plan every six months.
- Keep a log of all system changes and the business justification for each change.
- Train your finance and operations teams on the compliance features of your ERP.

Your ERP as a Compliance Partner
The question is not whether MAS will audit your firm. The question is whether your ERP will help you pass or fail. A well-configured ERP system with strong audit trails, enforced segregation of duties, and automated reporting is your best ally during a regulatory inspection. A system that lacks these features becomes your biggest risk.
