Internal Audit Support for Local and Canada-Wide Teams
Our internal audit services in Mississauga are useful for owner-managed companies, growing private businesses, groups with several locations, not-for-profit organizations and teams that need a structured review of risk and controls. Work can be completed locally in the GTA or coordinated with teams across Canada.

We start with the problem you need to solve. That could be
- inconsistent approvals
- repeat errors
- weak segregation of duties
- slow processes
- poor documentation
- system access concerns
- missed compliance steps
- or management not receiving reliable information on time
When an Internal Audit Review Is Worth Doing
Your business has grown faster than its controls
Your business has grown faster than its controls. Processes that worked for a small team can break when sales, staff, locations and transaction volumes increase. We review whether responsibilities, approvals and records still match the size of the business.
The same errors keep coming back
The same errors keep coming back. Repeat errors often point to a process or control problem, not a one-time mistake. We trace the issue to its source and recommend a practical fix.
Management lacks clear oversight
Management lacks clear oversight. If leaders rely on manual reports, delayed reconciliations or different versions of the same data, we review the reporting process and the controls behind it.
You are changing systems or processes
You are changing systems or processes. A new ERP, accounting platform, payroll system, approval workflow or operating model can create control gaps during the change. A focused review helps identify them early.
Your board, investor or funder wants stronger governance
Your board, investor or funder wants stronger governance. A structured internal review can show how key risks are identified, monitored and addressed, with clear ownership for follow-up actions.
You need a repeatable internal audit plan
You need a repeatable internal audit plan. Instead of reacting to issues one at a time, we help build a prioritized plan that focuses review effort on the areas with the greatest business impact.
Internal Audit Consulting Services Built Around Your Risks
Our internal audit consulting services can be used for one focused project, several process reviews, or an ongoing internal audit plan. The scope is based on your risk profile, business model, governance needs and available internal resources.
Risk Assessment and Audit Planning
We map major processes, discuss business objectives and identify the risks that could affect them. We then prioritize review areas based on impact, likelihood, change, past issues and management concerns.
Process and Operational Reviews
We walk through how a process works from start to finish, compare the documented process with actual practice, identify gaps and recommend simpler or stronger steps.
Control Design and Testing
We identify key controls, review how they are designed, test selected transactions or evidence, and document where controls are working or need improvement.
Compliance Reviews
We review whether internal procedures and selected business activities are being carried out in line with the policies, contracts or regulatory requirements that apply to the agreed scope.
Data and Technology-Focused Reviews
Where relevant, we review user access, system roles, approval settings, change controls, data handoffs and reporting dependencies that affect the process under review.
Reporting and Remediation Support
We provide clear findings, risk ratings, recommended actions, responsible owners and target dates. We can also follow up on agreed actions and update the issue tracker.
Internal Controls Audit Support for Key Business Processes
Our internal controls audit support focuses on the controls management relies on every day. We can review approvals, reconciliations, user access, segregation of duties, supporting documents, exception handling and management review controls within the agreed process.
Common review areas include
- revenue and billing
- purchasing and payables
- payroll
- inventory
- cash handling
- expense claims
- month-end close
- financial reporting
- vendor management
- and system access
The work is designed to show which controls matter, whether they are being followed, and what needs to change.
Risk Based Internal Audit Planning That Focuses on What Matters Most
A risk based internal audit starts with the areas that could create the greatest financial, operational, compliance, technology or reporting impact. This prevents the review plan from giving the same attention to every process, even when the risks are very different.
The Institute of Internal Auditors released the current Global Internal Audit Standards in 2024, and they became effective on January 9, 2025. Where the engagement is intended to support an internal audit function, we can structure planning, documentation, reporting and follow-up with reference to current internal audit principles and the organization's own governance needs.
From Risk to Remediation: What the Work Looks Like
| Stage | What we do | What you receive | Management outcome |
|---|---|---|---|
| 1. Prioritize | Identify key risks and processes. | Risk map and agreed scope. | Review effort goes to the highest-priority areas. |
| 2. Understand | Walk through the process and identify controls. | Process notes and control matrix. | Everyone agrees on how the process actually works. |
| 3. Test | Review selected evidence and transactions. | Testing results and exceptions. | Gaps are supported by clear evidence. |
| 4. Report | Rate issues and explain the business impact. | Findings report and action list. | Management sees what needs attention first. |
| 5. Remediate | Agree actions, owners and target dates. | Management action plan. | Fixes become assigned work, not forgotten recommendations. |
| 6. Follow up | Check progress on agreed actions. | Updated remediation tracker. | Leadership can see what is open, overdue or closed. |
Internal Audit Outsourcing Canada: Choose the Support Model That Fits
Our internal audit outsourcing Canada support can be structured around the resources you already have. You do not need to build a large in-house team before you can start reviewing risk and controls.
Project-based
- Best for
- One process, location or risk area needs review.
- How Bestax supports you
- We scope, test, report and support remediation for the agreed project.
Co-sourced
- Best for
- You have internal staff but need added capacity or a specific skill set.

- How Bestax supports you

The right model depends on the size of the organization, available staff, frequency of reviews, specialist needs and how governance wants findings reported. We define roles before work starts so management knows who owns the process, who provides evidence and who approves remediation.
What You Receive From an Internal Audit Engagement
A useful internal audit should leave your team with more than a list of problems. Our deliverables are designed to help management act.
A clear engagement scope and review objectives.
A risk and control matrix for the process under review.
Documented testing results and exceptions.
Findings written in plain language with practical risk ratings.
Recommended actions that explain what should change and why.
A management action plan with owners and target dates.
A remediation tracker for open, overdue and completed actions.
A closing discussion so management understands the findings before the report is finalized.
Our Internal Audit Process
Scope the Review
We discuss the process, concerns, past issues, systems, locations and stakeholders. We agree on objectives before requesting detailed records.
Assess Risk
We identify the risks that could stop the process from meeting its objective and decide which controls need the most attention.
Walk Through the Process
We speak with process owners, review policies and trace how transactions, approvals and data move through the workflow.
Test Selected Controls
We review selected evidence to see whether key controls are designed clearly and being followed in practice.
Report Findings and Actions
We explain the issue, evidence, business impact and recommended action in simple language. Management has a chance to provide context before finalization.
Track Remediation
Where included in the scope, we follow up on agreed actions and update the status so leadership can see what has been completed.
What We Need to Start
The exact list depends on the process. We request only the information needed for the agreed review.
Current policies, procedures and approval limits.
Process maps or workflow notes, if available.
Organization chart and key role descriptions.
System access or user-role listings relevant to the review.
Selected transaction reports or supporting records.
Prior internal review findings and open action items.
Compliance checklists or contract requirements relevant to the scope.
Management reports used to monitor the process.
Why Choose Bestax for Internal Audit and Controls Support?

Practical Findings, Not Long Reports
We focus on issues management can understand and act on. Each finding explains the risk, evidence and recommended next step.
Flexible Scope
You can start with one high-risk process and expand only when the first review shows value.
Accounting and Process Knowledge
Because controls often connect with bookkeeping, payroll, tax, reporting and accounting systems, our broader accounting knowledge helps us understand how one process affects another.
Local Support With Canada-Wide Delivery
Our Mississauga office gives GTA businesses a local point of contact while the work can also be coordinated remotely across Canada.
Follow-Up Built Into the Work
A recommendation has little value if nobody owns it. We can help turn findings into tracked actions with clear owners and target dates.

Flexible Internal Audit Support for Mississauga and Canada-Wide Teams
A second reason businesses choose Bestax is flexibility. A growing company can start with one process, while a larger team can build a rolling plan across finance, operations, payroll, systems, vendors or other priority areas.
For co-sourced internal audit work, management can keep part of the capability in-house while we add review capacity, structured testing, documentation and remediation tracking where the team needs support.
For control testing work, we agree on the exact control objective before testing begins. This keeps the review focused on whether the selected process is designed and operating in a way that supports management's objective.
A later risk-focused review cycle can use previous findings, new risks and business changes to decide what should be reviewed next. This creates a practical review plan instead of repeating the same checks every year.
Where a business wants ongoing coverage, an outsourced internal audit model can turn the agreed risk plan into scheduled reviews, reporting and follow-up without building a full internal team at once.
Across all of this work, our Canada-wide internal audit support remains focused on management and governance needs: understanding risk, testing controls, improving processes and tracking agreed actions.

We plan interviews, evidence requests and testing around your team's availability. The scope is agreed in advance so staff know what is needed and who is involved.
We explain the issue, the evidence, the business impact and a practical action. Management can respond before the report is finalized, and the action can be assigned to an owner with a target date.
Yes. We can support remediation planning, process changes, documentation and follow-up within the agreed scope. Management remains responsible for operating the process and approving changes.
