Fractional HR vs Ad Hoc HR Consulting vs Hiring an HR Manager: Which Is Right for Your Business?

Quick Answer: There isn’t one HR solution that suits every growing business. If you need help with a single issue or project, ad hoc HR consulting may be all you need. If your business needs ongoing strategic HR support but you’re not ready for a full time hire, Fractional HR is often the better fit. If your business has enough day to day HR work to keep someone fully occupied, hiring an internal HR Manager may be the right next step.

A common question from business owners is, “What’s the difference between Fractional HR, HR consulting and hiring an HR Manager?”

It’s a great question, but I don’t usually answer it by explaining the three options straight away.

Instead, I ask a few questions about what’s happening in the business.

Has the business been growing quickly? Are managers struggling with performance conversations? Is recruitment taking longer than it used to? Are the founders spending more time dealing with people issues than they want to?

The reason I start there is because choosing the right HR support isn’t really about understanding different service models. It’s about understanding what your business needs at this stage of its growth.

I’ve spoken with businesses that assumed they needed a full time HR Manager when they only needed a few days of strategic support each month. I’ve also met with businesses that kept relying on project-based consulting long after they needed someone involved in leadership discussions and planning.

Neither approach was wrong, it simply wasn’t the right fit for where the business was at the time.

That’s why I think this decision is less about comparing services and more about matching the right type of support to the challenges you’re trying to solve.

Why Choosing the Right HR Support Isn’t Always Straightforward

When businesses are small, HR often happens organically.

The founders recruit new employees, managers handle day to day conversations, and everyone knows each other well enough that communication feels fairly easy.

As the business grows, things begin to change. New managers step into leadership roles for the first time. Recruitment becomes more frequent. Teams become larger and sometimes spread across different locations. Performance issues become more complicated, and leaders find themselves spending increasing amounts of time dealing with people matters rather than focusing on clients, strategy or business growth.

I remember talking with a business owner whose team had grown to around 35 employees. She told me she knew they needed more HR support, but every option felt like a big commitment.

Hiring an HR Manager was too expensive, but using a consultant felt too temporary.

She’d heard the term Fractional HR but wasn’t really sure how it differed from traditional HR consulting.

That’s actually a very common position for growing businesses to be in.The challenge isn’t usually deciding whether HR matters. Most business owners already know their people are critical to the success of the business.

The challenge is understanding what type of support will genuinely help them move forward without paying for services they don’t yet need or delaying support until people challenges become much bigger than they need to be.

Start With the Problem, Not the Solution

One of the mistakes I see businesses make is starting with the solution rather than the problem.

They decide they need an HR Manager because another business of a similar size has one, or they call an HR consultant because a specific issue has come up.

Sometimes they start looking at Fractional HR because they’ve heard someone mention it on LinkedIn or in a networking group. None of those are bad starting points, but they don’t necessarily answer the most important question.

What is the business actually trying to achieve?

For example, if you’re preparing for rapid growth and your managers need ongoing coaching, recruitment support and better performance processes, a one-off consulting project probably won’t give you the continuity you’re looking for.

On the other hand, if you simply need someone to review your employment contracts or provide advice on a Fair Work matter, bringing in ongoing HR support may be more than you need.

I’ve found that when we focus on the challenge first, the right solution usually becomes much clearer.

When Ad Hoc HR Consulting Is the Right Choice

Ad hoc HR consulting works well when you have a clearly defined issue that needs specialist advice or support.

Perhaps you’ve received a Fair Work claim and need guidance on the best way to respond. Maybe you’re updating employment contracts, reviewing policies or investigating a workplace issue. You might simply need an experienced HR professional to provide advice before making an important decision.

In those situations, project-based consulting can be exactly the right approach. The engagement is focused, practical and designed to solve a specific problem before coming to an end.

Many businesses use ad hoc HR consulting very successfully, particularly when they’re relatively stable and don’t have an ongoing need for strategic HR involvement.

Where I sometimes see businesses run into difficulty is when every new people challenge becomes another separate consulting project. One month it’s recruitment, the next month it’s performance management, then it’s leadership development, employee engagement, onboarding etc.

Individually, each project makes sense. Collectively, they can become a sign that the business is no longer dealing with isolated issues. It’s experiencing ongoing people challenges that would benefit from a more consistent approach.

That’s often the point where business owners start asking whether they need something more than project based consulting.

Sometimes the answer is yes. Sometimes it’s not.

The important thing is recognising when the pattern has changed.

Prefer to watch rather than read?

One of the questions I’m asked most often is what the difference is between HR consulting and Fractional HR. In this short video, I explain how the two approaches differ and why the right choice depends on what your business needs.

When Fractional HR Is the Better Option

For many of the businesses I work with, Fractional HR sits comfortably between ad hoc consulting and employing someone internally.

It’s ongoing, which means you’re not starting from scratch every time a new challenge comes up, but it also gives you flexibility because you’re only accessing the level of support your business actually needs.

One of the reasons we really enjoy working in a Fractional HR model is that it allows us to really understand a business over time. We get to know the leadership team, the managers, the culture and the goals of the business. That context makes a significant difference because people decisions rarely happen in isolation.

A recruitment challenge is often connected to onboarding. Performance issues are often linked to manager capability. Employee engagement is usually influenced by communication, leadership and culture rather than one single initiative.

When someone understands how all those pieces fit together, it’s much easier to build practical solutions that continue to work as the business grows. This is where Fractional HR is quite different from project based consulting.

Rather than solving one issue and moving on, you’re building capability within the business. Managers become more confident. Recruitment becomes more consistent. Performance conversations happen earlier. Leaders spend less time reacting because stronger systems and processes are already in place.

For many small and medium sized businesses, that’s exactly what they need. They don’t necessarily need another employee. They need experienced guidance that grows alongside the business.

If you’re still deciding whether your business has reached that point, our guide to 10 signs your growing business is ready for Fractional HR can help you assess where you are today.

When Hiring an HR Manager Makes Sense

There absolutely comes a point where bringing HR in house is the right decision.

As businesses become larger, the amount of day-to-day HR work naturally increases. Recruitment becomes a constant activity rather than an occasional one. Leaders need regular support. Employee relations become more complex and there is often enough work to keep an experienced HR professional fully occupied.

An internal HR Manager can become deeply embedded in the business and provide immediate day to day support across the organisation.

Where I encourage business owners to pause is before assuming they’ve reached that point.

I’ve seen businesses with fewer than 50 employees successfully supported through a Fractional HR model for many years because they needed strategic leadership rather than someone sitting in the office every day.

I’ve also seen businesses of a similar size that genuinely needed an internal HR Manager because of the complexity of their operations, multiple locations or rapid recruitment requirements.

There isn’t a magic employee number where every business should hire internally.

The decision is really about workload, complexity and what the business is trying to achieve over the next few years.

If you’re specifically weighing up those two options, we’ve explored the decision in more detail in our guide to choosing between Fractional HR and hiring an HR Manager.

A Simple Comparison of Your Options

Sometimes it helps to step back and look at the three approaches side by side.

Looking at the table, you’ll probably notice that there isn’t a “best” option. Each approach has its place.

The important thing is matching the level of support to what your business actually needs today rather than what you think you should have.

It’s Not Just About Cost

It’s very tempting to compare these options based purely on price.

Understandably, business owners want to know whether hiring an HR Manager or engaging Fractional HR is the more affordable option.

Cost certainly matters, but I’ve found it rarely tells the whole story. The more useful question is whether you’re investing in the right capability at the right time.

If a business hires a full time HR Manager before there’s enough strategic HR work to justify the role, there’s a risk that person ends up taking on administrative tasks simply to stay busy.

Equally, if a business relies on ad hoc consulting when managers need regular coaching and ongoing support, leaders often continue carrying people responsibilities that should have been shared much earlier.

The goal isn’t to spend the least amount of money, it is to invest in the level of HR support that allows your leaders to focus on growing the business while creating a positive experience for your employees.

If you’re interested in comparing the investment in more detail, we’ve put together a guide explaining Fractional HR costs and how they compare with hiring internally.

One of the things I often remind business owners is that people challenges don’t stay still.

• Businesses grow.
• Managers develop.
• New opportunities arise.

The HR support that’s right today may not be exactly the same in two or three years’ time, and that’s perfectly normal.

The best approach is the one that gives your business the right level of expertise now while leaving room to adapt as your needs change.

The right HR support isn’t just about solving today’s problems. It’s about helping leaders build confidence as the business grows.

Common Mistakes I See Growing Businesses Make

One of the benefits of working with so many growing businesses is that you start to notice patterns.

The businesses are all different, but the decisions they wrestle with are often surprisingly similar.

One mistake I see is businesses trying to solve every people challenge with a separate consulting project.

They might engage someone to help with recruitment, then bring someone else in for performance management, then another consultant for leadership development. Each project delivers value, but over time the business ends up managing multiple pieces without an overall people strategy connecting them together.

Another common mistake is hiring an HR Manager too early. The intention is usually good. The leadership team recognises that people are becoming more important and wants to invest before problems arise.

The challenge is that there isn’t always enough strategic HR work to justify a full time position.

I’ve seen situations where experienced HR professionals end up organising office events, managing facilities or taking on administrative tasks that don’t really use the skills they were hired for. That’s frustrating for the business because they’re paying for capability they’re not fully using, and it’s often frustrating for the HR professional as well.

The opposite can also happen.

Business owners sometimes wait far too long before asking for support because they feel they should be able to manage everything themselves.

As a result, managers receive very little guidance, recruitment becomes inconsistent, performance conversations are delayed and leaders spend more time reacting to issues than planning ahead.

Most businesses don’t need to be at either extreme. The goal is simply to have the right level of HR capability for the stage your business is in today.

How to Decide Which Option Is Right for Your Business

If we were sitting down over a coffee together, these are probably the questions I’d ask before recommending any particular approach.

• How much of your week is currently spent dealing with people issues?
• Are your managers confident leading their teams, or do they regularly come to you for help?
• Is recruitment becoming more frequent?
• Are you planning significant growth over the next year?
• Do your current HR processes give you confidence, or are they mostly being created as situations arise?

The answers to those questions usually tell us much more than the number of employees on the payroll.

Some businesses with 20 employees genuinely benefit from ongoing HR support because they’re growing quickly and developing new managers.

Other businesses with 60 employees have stable teams, experienced leaders and only need occasional advice.

That’s why I don’t believe there’s a perfect employee number where every business suddenly needs the same type of HR support.

It’s about understanding what’s happening inside your business rather than comparing yourself with someone else’s.

So, Which Option Is Best?

If your business only needs help with a specific issue or project, HR consulting is often the most practical solution.

If you’re finding that people challenges are becoming more regular and your leaders need ongoing support, but you’re not yet ready for a full time HR salary, Fractional HR is often the option that provides the greatest flexibility and long term value.

If your business has enough day to day HR work to keep someone fully occupied and you want an experienced HR professional embedded in your organisation every day, hiring an HR Manager may be the right next step.

None of these options are inherently better than the others, they’re simply designed for different stages of business growth.

The most important decision isn’t choosing the newest or most popular model. It’s choosing the one that gives your people and your leaders the support they need to build a stronger business.

Frequently Asked Questions

What is the difference between Fractional HR and HR consulting?

HR consulting is usually focused on solving a specific problem or completing a defined project, such as reviewing employment contracts or providing advice on a workplace issue. Fractional HR provides ongoing strategic support and becomes part of your leadership rhythm, helping your business build stronger people capability over time.

Is Fractional HR better than hiring an HR Manager?

Neither option is better in every situation. Fractional HR is often ideal for growing businesses that need experienced HR leadership but don’t yet have enough work to justify a full-time role. An internal HR Manager may be the better choice once there is sufficient ongoing HR activity to support a permanent position.

When should a business use ad hoc HR consulting?

Ad hoc HR consulting works well when you need help with a specific issue, such as a Fair Work matter, workplace investigation, policy review or recruitment project. If new HR challenges are arising regularly, it may be worth considering a more ongoing model of support.

How do I know if my business is ready for Fractional HR?

Businesses often benefit from Fractional HR when leaders are spending increasing amounts of time managing people issues, managers need more support, recruitment is becoming more frequent and growth is creating additional complexity. Our Fractional HR Readiness Checklist can help you assess whether your business has reached that point.

Which HR support option is most cost effective?

The most cost-effective option depends on the level of support your business needs. Ad hoc HR consulting is often suitable for occasional projects, Fractional HR provides ongoing expertise without the commitment of a full-time salary, and hiring an HR Manager becomes more cost effective when there is enough day to day HR work to justify a permanent role.
