Microsoft Internal Audit Software Consulting
Microsoft internal audit software describes the set of Microsoft 365 and Azure tools — Purview, Entra ID, Power BI, Power Platform, and SharePoint or Dataverse as a system of record — that an internal audit function assembles to plan, execute, and document risk-based audits, as an alternative or complement to a dedicated internal audit platform such as AuditBoard, Diligent, or TeamMate. This is not about auditing a specific ERP; it is about the toolset internal audit uses to run its own function, and it sits above whatever core financial system — Dynamics, SAP, Oracle, or another — the audits actually test. The distinction matters because internal audit teams that build their annual audit plan, risk assessment, and fieldwork documentation natively in Microsoft 365 face different evidence-integrity and workflow-enforcement questions than teams running a purpose-built audit management application.
Risk assessment and the annual audit plan without a dedicated risk register
A dedicated internal audit platform typically ships with a structured risk universe, a scoring methodology, and a workflow tying risk scores to audit plan prioritization. Building the equivalent in Microsoft 365 usually means a Dataverse table (or, for smaller teams, a SharePoint list) holding the risk register, with each risk scored on likelihood and impact fields and a Power BI report visualizing the resulting heat map. This works, and it gives internal audit leadership a live view of the risk universe rather than a static annual document, but the scoring methodology, the criteria for what counts as a SOX-relevant risk versus an operational risk, and the cadence for re-scoring all have to be defined and maintained outside the tool — Microsoft 365 provides the data structure, not the audit methodology.
The gap that shows up most often in Microsoft-native risk assessment is traceability from a scored risk to the specific audit engagement and, further, to the specific control tested. A purpose-built platform enforces that linkage structurally — you cannot close an audit without it referencing a risk. In Dataverse or SharePoint, that traceability is a lookup column someone has to populate consistently, and inconsistent population is exactly what an external auditor's walkthrough of the internal audit function's own risk-based approach will probe first, particularly under PCAOB AS 2201's expectations for how management identifies and prioritizes ICFR risk.
Fieldwork, workpapers, and reviewer sign-off inside SharePoint and Teams
Internal audit fieldwork conducted in Microsoft 365 typically lives across three surfaces: a Teams channel per engagement for auditor-auditee communication, a SharePoint document library for workpapers, and a Dataverse or Lists table tracking finding status and remediation. The auditor-auditee communication trail in Teams is itself evidence — a request for a screenshot, a clarifying question about a control's operation, and the auditee's response document the interactive nature of the testing, which is exactly what a paper-only workpaper often fails to capture. Retaining that Teams history for the audit cycle requires a Purview retention policy on the channel, which is not the default behavior for most Teams deployments.
The reviewer sign-off problem is structural, not technical. A dedicated platform enforces a review workflow — a workpaper cannot move to 'complete' without a reviewer's electronic sign-off distinct from the preparer's identity. Recreating that in SharePoint requires either a Power Automate flow that checks the modified-by field against a reviewer list before allowing a status change, or a disciplined manual process that an external auditor will test for exceptions. Teams that skip this and rely on a verbal or Teams-chat 'looks good' as their review evidence consistently find that finding during their own SOX ITGC testing of the audit function's change-management and review controls.
Reporting to the audit committee and closing the loop on remediation
Power BI's advantage for internal audit reporting is that a single dataset — the Dataverse or Lists-based finding tracker — can drive both the operational dashboard the internal audit director checks weekly and the formatted audit committee deck generated for quarterly board reporting, without re-keying data between two tools. This is a genuine cost advantage over licensing a separate reporting module in a dedicated platform, and it is one of the stronger reasons mid-market internal audit functions choose to stay Microsoft-native even as they mature.
The recurring weakness is remediation tracking discipline: a finding with an assigned owner and a due date in Dataverse does not, by itself, escalate or notify anyone when the due date passes, unless a Power Automate flow is built specifically for that purpose. Dedicated platforms treat overdue-finding escalation as a core feature; in a Microsoft-native build it is an explicit configuration task that is easy to skip during initial rollout and then discover is missing only when an auditor asks how management tracks remediation of prior-year findings — a question Section 404 management's-assessment documentation has to answer directly.
What actually differentiates the options
- ·A Dataverse or SharePoint-based risk register with defined scoring criteria and a documented cadence for re-scoring, not a static spreadsheet re-created annually.
- ·Purview retention policies applied to engagement Teams channels and SharePoint workpaper libraries, so auditor-auditee communication and evidence survive the full audit cycle plus look-back period.
- ·A Power Automate-enforced reviewer sign-off workflow that prevents a workpaper or finding from closing without a reviewer identity distinct from the preparer.
- ·Automated overdue-finding escalation (Power Automate notifications tied to due-date fields) rather than manual tracking of remediation deadlines.
- ·A single Power BI dataset feeding both operational dashboards and audit committee reporting, so board-level figures reconcile to the underlying finding tracker without manual re-keying.
Requirement, control, evidence
| Requirement | Control | Evidence |
|---|---|---|
| Risk-based audit planning must be documented and traceable (supports Section 404 management assessment) | Dataverse risk register with scored risks linked to specific audit engagements via a required lookup field. | Risk register export showing risk score, linked engagement, and last re-scoring date for a sample of SOX-relevant risks. |
| Audit workpapers must reflect independent reviewer sign-off, not preparer self-certification | Power Automate flow blocking a workpaper status change to 'reviewed' unless the acting user differs from the preparer field. | Flow run history and workpaper metadata for a sample of engagements, confirming reviewer identity differs from preparer identity. |
| Auditor-auditee communication and evidence must be retained for the audit cycle and remediation look-back period | Purview retention policy applied to engagement Teams channels and SharePoint workpaper document libraries. | Retention policy configuration export and a sample Teams channel showing message history intact through the retention window. |
| Remediation of findings must be tracked to closure with timely escalation | Power Automate notification flow triggered when a finding's due date passes without a status change to closed. | Escalation notification log cross-referenced against a sample of overdue findings, confirming notification fired on schedule. |
What this actually costs
| Cost driver | Low | High | What moves it |
|---|---|---|---|
| Dataverse-based risk register, audit plan, and engagement tracker design and build | $40,000 | $110,000 | Scales with number of auditable entities and whether the risk methodology is being defined for the first time or migrated from an existing tool. |
| Workflow automation (reviewer sign-off enforcement, retention policies, remediation escalation) | $25,000 | $70,000 | Depends on number of distinct workflows required and complexity of the existing SharePoint/Teams environment being retrofitted. |
| Power BI reporting suite (operational dashboard plus audit committee reporting deck) | $15,000 | $50,000 | Higher end reflects environments requiring row-level security so business-unit auditees see only their own findings. |
- · Ranges assume existing Microsoft 365 E3/E5 and Power Platform per-app or per-user licensing already in place.
- · Figures are illustrative estimates based on typical mid-market internal audit functions of 3-10 auditors, not quotes for a specific organisation.
- · Estimates exclude the cost of defining the risk assessment methodology itself, which is a governance decision independent of the tooling.
A representative scenario
A hypothetical $800M industrial manufacturer runs a five-person internal audit function that has used SharePoint and Excel for a decade and is evaluating whether to license a dedicated internal audit platform ahead of its second year of 404(b) compliance. A tooling assessment in this pattern typically finds that the existing SharePoint-based workpaper library has no retention policy, that the finding tracker's 'status' field is manually updated with no escalation when remediation deadlines pass, and that roughly a third of closed findings in the prior year's sample have no distinguishable reviewer sign-off separate from the preparer. Rather than migrating to a licensed platform immediately, the remediation path in this scenario is usually to rebuild the tracker in Dataverse with required reviewer and due-date fields, add Purview retention to the workpaper library, and layer in a Power Automate escalation flow — closing the specific gaps an auditor would test without taking on a new platform's implementation timeline. The decision to eventually move to a dedicated tool is revisited once the audit plan grows beyond roughly 25-30 engagements a year, at which point manual Power Automate maintenance becomes its own burden. This progression is common enough across Microsoft-native internal audit functions to be described here as illustrative, not as a specific client outcome.
Common questions
It is not a single product — it is the combination of Dataverse or SharePoint as a system of record, Power Automate for workflow enforcement, Purview for retention and audit logging, and Power BI for reporting, assembled to run the internal audit function's own planning, fieldwork, and reporting process, as an alternative to licensing a dedicated platform like AuditBoard, Diligent, or TeamMate.
