Internal Audit Co-Sourcing For Internal Audit and Risk Functions
Senior practitioners. Flexible delivery. Built to support your team.
Cherry Hill Advisory provides experienced internal audit professionals who work alongside your team to deliver specialized expertise, additional capacity, and project-based support.
Whether supporting a specific audit, addressing a complex risk area, or helping execute the audit plan, our practitioners integrate directly with internal audit teams to deliver high-quality results.
Internal Audit Teams Need Flexible Access to Specialized Expertise
Internal audit co-sourcing is when an outside firm works alongside your in-house internal audit team on specific audits or capacity gaps, under your Chief Audit Executive's direction. Your team keeps the plan, the relationships, and the findings. We bring senior practitioners for the work that needs them. For organizations that want the whole function run externally, we deliver internal audit outsourcing on the same senior-led terms.
Internal audit leaders today face expanding expectations across cybersecurity, fraud risk, regulatory compliance, and emerging technologies. Adding permanent headcount for every specialized area isn’t always practical.
Cherry Hill Advisory allows internal audit teams to bring in experienced practitioners when additional expertise or capacity is needed.
Our practitioners integrate seamlessly with internal audit teams while maintaining existing methodology, governance structures, and reporting frameworks.
Internal Audit Support That Fits How Your Team Works
Internal Audit Co-Sourcing
We work alongside your team to execute audits already on your plan. You retain control of scope and reporting. We provide additional capacity and subject-matter expertise where coverage is thin or timelines are tight. This includes fieldwork, walkthroughs, control testing, documentation, and reporting support that aligns with your methodology and standards.

This includes developing risk-based audit plans, communicating with executive leadership and the audit committee, refining audit methodology, and aligning audit priorities with enterprise risk.We step in at the leadership level when maturity, transition, or growth demands it.
Fraud Risk Advisory
We support internal audit teams in assessing fraud risk exposure and strengthening investigative readiness. This includes fraud risk assessments, investigation support, hotline allegation reviews, and root-cause analysis to help organizations identify control gaps and reduce fraud risk.

Our practitioners integrate into your existing audit process to strengthen coverage while maintaining professional standards and audit defensibility.

Enterprise Risk Management
We support organizations in developing and strengthening enterprise risk management programs that connect risk strategy with internal audit execution. This includes ERM framework design aligned with COSO or ISO 31000, development of risk appetite and tolerance statements, and building enterprise risk registers and heat maps. We also help integrate ERM insights directly into the internal audit planning cycle so audit resources are focused on the areas of highest risk.
Available on every co-source
Your senior team, with an AI bench behind it when you want one
A Cherry Hill co-source is led by a practitioner who has run the function you are asking us to support. If it helps your engagement, that practitioner can also draw on our AI specialist bench for the volume work: access pulls, evidence collection, SOC report reviews, workpaper organization. You decide with us whether and where it fits. Either way, a named practitioner reviews and signs every finding.
Core engagement team, on request
Specialist bench available on request. You never manage or log in to any of it. Our practitioners direct the work and own the outcome.

Big 4 Expertise. Boutique Delivery.
Many advisory firms bring rigid methodologies and layered reporting structures. That model does not always fit internal audit environments that require agility and discretion.
Cherry Hill adopts a white-glove service model that combines Big 4 experience with boutique attention. We integrate seamlessly with internal teams. We move with tech-enabled speed, and communicate clearly with stakeholders at every level.
Senior professionals lead every engagement. There is no bait-and-switch model. There is no unnecessary overhead.
We are brought in to solve problems, not create them.
Internal Audit Co-Sourcing Questions, Answered
What is internal audit co-sourcing?
Internal audit co-sourcing is when an outside firm works alongside your in-house internal audit team on specific audits or capacity gaps, under your Chief Audit Executive's direction. The senior practitioners brought in plug into the existing function rather than replacing it, which is why it works when the alternative (hiring or running a Big Four engagement) is too slow or too heavy. Cherry Hill's co-sourcing model is senior-led, so the practitioner who shows up at the kickoff is the practitioner doing the work.
How is co-sourcing different from outsourcing internal audit?
Co-sourcing keeps the internal audit function in-house and adds external expertise on specific audits or specialty areas. Outsourcing replaces the function entirely, which most organizations with a real internal audit charter do not want, since the function exists to provide independent assurance from inside the company. Cherry Hill leads with co-sourcing, so your CAE keeps ownership of the plan, and supports full outsourcing where a company has no internal function to build around.
When should we co-source internal audit work?
Co-source when your team has the right judgment but not the right capacity or specialty for the audit in front of them. Common triggers include AI governance audits, third-party risk work, cybersecurity audits, and External Quality Assessment preparation. The pattern that does not work is co-sourcing as a permanent way to avoid building team depth; co-sourcing extends the team, it does not replace headcount strategy.
How is Cherry Hill different from a Big Four firm?
The senior practitioner who sells the engagement is the senior practitioner doing the work, not a partner handing off to a senior manager handing off to a team of juniors. Cherry Hill is also boutique in size, which means the practice owner is involved in every engagement, and fixed-fee or scoped-engagement structures replace the leverage-model hourly billing common at large firms. Both models have their place; companies pick Cherry Hill when senior judgment matters more than scale.
