How Much Does Outsourced HR Cost? (2027 Price Guide)

TLDR:

• Hourly HR advice costs about $90 to $250 an hour, depending on seniority.
• One-off projects, like a compliance audit, start at around $1,800.
• Ongoing fractional HR runs roughly $2,000 to $4,900 a month for most growing companies, and up to about $8,000 for more hours or more senior support.
• Castle HR's most popular plan is $2,900 a month, with a dedicated senior HR professional.
• A full-time HR manager in Toronto costs about $112,500 a year in median wages alone, before benefits and recruiting.

You didn't start a company to become its HR department. You started it for what's on the other side of all that risk: the front of the plane, where the champagne shows up before the seatbelt sign goes off, the kids' school with the crest on the blazer, and the cottage dock where your phone stays face-down all weekend because, for once, nobody needs a single thing from you. 

More freedom, more time with the people you love and more sand between your toes.

Now picture a Tuesday night at 9:47, and instead of building the thing you started the company to build, you're Googling "can I legally put someone on a performance plan while they're on vacation?" (Spoiler: the internet has 47 opinions, and you don’t know which one is right.) 

A manager has just Slacked you a screenshot with the words "quick question 🙃," which, as every founder knows, is never quick and rarely a question. 

And somewhere in a folder called FINAL_final_v3 there's an employee handbook you downloaded in 2021 that still references a ping-pong table you sold for parts.

You never noticed you were always wearing the HR hat. It became more noticeable on your head one morning, like a pigeon choosing a statue, and it gets a little heavier with every hire. Here's how you know it's sitting on you right now:

• Managers bounce decisions back to you like a boomerang with a homing chip.
• Every new hire is a fire-drill scramble of job-board posts, gut-feel interviews, and a gambling handshake.
• Performance problems sit for months, going bad quietly in the back of the fridge like forgotten soup.
• Your policies live in your head, which is a lovely place, but not legally defensible.
• You have growth plans and no strategy for how to help the team and leaders you need to reach your goals.

Running a growing company this way is like juggling flaming chainsaws on a unicycle while someone keeps lobbing Slack notifications at your head. 

When a chainsaw finally falls, that's when founders start pricing out HR help, and discover that nobody seems to agree on what it costs.

How much does outsourced HR cost?

Outsourced HR in costs about $90 to $250 an hour for advice, from around $1,800 for a one-off project, and roughly $2k to $5k a month for ongoing fractional HR at most growing companies, with more senior or higher-hour retainers reaching about $8,000. 

What you pay depends on what you're buying and who you buy it from.

Let's not beat around the bush, and talk about the real published prices, the kind most providers hide behind a polite "book a discovery call" button. There are three ways to buy, and each one buys something completely different.

The easiest way to understand the three models is to think of hiring a chef.

Hourly is a chef who answers the phone. Brilliant when you know what you're cooking and just need to ask whether the chicken looks weird. But the rate is slight of hand: 

A project is a chef who writes you a recipe. Perfect for one defined job, like a policy audit or an onboarding build. The catch is where the project ends, so make sure "rollout" doesn't secretly mean "we give you the PDF and a bill."

Monthly is a chef who moves into your kitchen part-time. They learn your pantry, train your line cooks and notice the fridge is making that noise before it explodes. It's worth it when the need is ongoing, but a recurring invoice doesn't prove anyone is being proactive, so ask how they choose priorities and follow through between meetings.

How much does an HR Manager cost?

A full-time HR manager in the Toronto region earns a median of $112,500 a year, according to Canada's Job Bank, before benefits and payroll contributions. 

A full-time HR manager in New York or Texas earns a median of $136,000 a year, according to Salary.com, before benefits and payroll contributions. 

More junior HR roles cost less, but they also do less of the senior work a growing company usually needs.

Add benefits, payroll contributions and a recruiter's fee (often around 20% of first-year salary, which on a $112,500 hire is roughly $22,500, or a perfectly respectable used car), and the real first-year cost of an HR manager climbs well past the salary itself. 

For a 25-person company, that's a big, permanent line item for a job that may not be needed. 

Carlos Midence, a CEO you'll meet in a minute, called this stage "the awkward teenager phase": too big to wing it, too small to build a department, and outgrowing your clothes every quarter.

Is outsourced HR cheaper than hiring an HR manager?

For most growing companies under about 75 employees, a fractional HR partner typically costs about a third to a half of a full-time HR manager's median salary, before you even add benefits. 

But it's not the same purchase, and doing it yourself isn't as free as it looks, so compare all three options honestly.

Doing it yourself looks free until you do the napkin math, and then it looks like the most expensive HR department. 

Five hours a week on people stuff (interviews you didn't prepare for, manager therapy sessions disguised as "syncs," employment contracts read with the expression you usually save for IKEA instructions) adds up to 260 hours a year. That's six and a half full work weeks of the one person who's supposed to be steering the ship, down in the engine room with a mop. 

The worst part is that napkin doesn't even include the risks:

• The wrong hire costs you twice. Once in the time and money to hire them, and again when you unwind it while the whole team watches.
• The unaddressed underperformer becomes the standard. Your best people notice what you tolerate, and then they update their LinkedIn.
• The rules change under your feet. It sometimes feels like every year there are more policy changes than grains of sand in the Sahara!

A full-time HR manager isn't the wrong answer either, just a different purchase. A full-time hire gives you a full-time person, so if you truly have a full-time HR workload, hire one. 

If you have a senior-judgment workload that's growing faster than a sourdough starter in July, a fractional partner usually gets you more for less. For the full decision, find our blog Should You Hire an HR Manager or Outsource HR?

Why do outsourced HR quotes vary so much?

Outsourced HR quotes vary because providers are selling different people, different responsibilities and different amounts of actual doing, all wearing the same trench coat labelled "strategic HR support." 

Before you compare numbers, make every provider answer these five questions:

1. Who will actually do the work? Meet that person, not just the silver-tongued senior partner on the sales call.
2. Have you handled a company like mine? A 40-person SaaS company and a 40-person consulting firm are different animals wearing the same headcount.
3. What does "recruitment support" mean here? Scorecards and hiring-manager coaching, or just a job post with nicer adjectives?
4. Will you implement it, or hand it over? A performance-review form doesn't teach a nervous manager how to have a hard conversation.
5. What happens when we change? Get capacity, response times and extra-cost terms in writing before the surprise invoice and while everyone still likes each other.

If you remember one thing from this article, compare HR proposals on who does the work and what actually gets implemented, not on the number at the bottom. We’ve had to step in and clean up countless times because plenty of providers are all waffle and no syrup. 

Is outsourced HR worth the cost?

Outsourced HR is worth the cost when it takes real work off the founder's desk and builds systems that make the whole team better. The test isn't the monthly fee but whether, a year later, people problems stop routing through you and the business grows faster because of it.

That's the reason I started Castle HR in Toronto in 2019, after my own career ended with a meeting I didn't see coming. What I kept noticing afterwards was founders, brilliant ones, drowning in people problems with nobody senior in their corner. Big companies had HR departments, but small companies had Google and outdated templates.

Shoplogix, a Canadian software company, is a perfect example of what changes. Before it started working with Castle HR in December 2023, CEO Carlos Midence was the HR department: recruiting, onboarding, benefits, employee relations, manager questions and a global expansion, all stacked on his desk like a Jenga tower in an earthquake. 

We matched Shoplogix with a dedicated Senior HR Professional who met Carlos every week, worked directly with his managers and built the hiring, onboarding and people systems around the company's growth goals, then made sure people actually used them. 

As Shoplogix matured, the work grew with it, into leadership succession and even acquisition-related HR.

"Two and a half years in, HR just isn't something I worry about anymore." — Carlos Midence, CEO, Shoplogix

You can read the full case study on Shoplogix here.

Shoplogix isn't alone. More than 50 Castle HR clients have made The Globe and Mail's list of Canada's fastest-growing companies, and Castle HR holds a 4.9-star average on Google Reviews.

How much does Castle HR cost, and what's included?

Castle HR's most popular subscription costs $2,900 a month, or $34,800 a year, and includes a dedicated senior HR professional who works part-time as part of your team. Faster-growing companies can move to higher tiers.

That's under a third of a full-time Toronto HR manager's median salary, before a single benefit, and we can start within a week. 

Think of it as garlic or a stake to the heart of that time-hungry vampire that feeds on your evenings. Here's exactly what's on the table with Castle HR:

And here's what you still own, because no honest partner hides this: leadership still makes the business calls, and managers still have to manage. The weekly meeting keeps us in context.

Is it a fit? Castle HR is built for growing software and professional services firms, which make up about 80% of the client portfolio, usually from roughly 20 employees onward. It's probably not your answer if:

• You need one specific job done, and someone internal can own it after. Buy a project.
• You already have an HR generalist who just needs occasional senior advice. Buy hourly.
• You need payroll processed or employees administered. Look at a payroll provider or employer of record.

We'd rather tell you that on a call than bill you for finding out.

One more thing. Agree on how you'll measure success before you sign with anyone. Which decisions should managers stop escalating? Which process should be running, and actually used? A new process nobody follows is just the old process nobody followed, wearing a fresh coat of paint.

About the author. Tom Nickalls is the founder and CEO of Castle HR, a Toronto-based fractional HR firm he started in 2019. Castle HR works exclusively with growth-stage companies across Canada and the U.S., pairing each with a dedicated senior HR professional.

We've sat with more than 250 growth-stage founders at this exact fork, and this is the simple test we walk them through. 

Follow the arrows with your actual company in mind, not the one in your pitch deck.

Where did you land?

• Yes to both means hire a senior HR leader. You have the need and can pay for it, so go find someone brilliant.
• No full-time HR job yet, you feel you are missing your targets or going to. This is where you need a fractional HR partner, and exactly the stage Castle HR was built for.
• A full-time job, but not the budget or the boss for a senior leader: bring in a fractional HR partner who will build what you need slower but cheaper than an internal Senior HR hire.
• No full-time job and no growth squeeze: buy hourly advice or a project. Your people side is calm. Keep your money, and call someone when a specific problem shows up.

Already have an HR manager on the team? Run the test for the senior work only. If you land on fractional, you don't replace them, you simply complement them with a Senior HR Pro.

Landed on fractional? Book your HR Escape Plan call → and le’ts have a nice chat.

This was incredibly simple so let's slow down and pressure-test each question, because this is exactly where smart founders talk themselves into the wrong answer.

How do you know if you have a full-time HR job?

You have a full-time HR job when there are 40 hours a week of senior people work, meaning building systems and making judgment calls, not just admin. In Castle HR's experience, most growth-stage companies have plenty of HR pain but nowhere near 40 hours of senior HR work.

This is where founders fool themselves because HR pain can be loud. It feels full-time because it lands on you at the worst possible moments, like a seagull that wants all your fries.

But loud pain doesn’t mean there is a full workload.

Let's start with understanding if you need Senior HR help or not.

Now identify where your challenges are and the kind of work you think you need. 

A full-time Senior HR Pro usually means you have a team of 50+ or are 30+ but are hiring 2-5 people a month consistently.

If that is you, you likely need a Senior HR Professional, if not, the good news is, budget-wise, you probably need Fractional HR.

Can you afford and manage a senior HR leader?

A senior HR leader costs more than most growth-stage founders budget for, and you need someone senior to manage them. When either piece is missing, the "HR manager" job post quietly becomes a junior hire, and the founder ends up managing HR instead of escaping it.

Start with the price tag. Canada's Job Bank puts the median human resources manager in the Toronto region at about $112,500 a year, before benefits. 

This is not the battle-tested leader who has scaled three companies and can smell a toxic manager from the parking lot... they cost a lot more.

So the founder sees the number, does the face you make when the sommelier mentions the price after pouring, and rewrites the job post. "HR Manager" becomes "HR Generalist, 3–5 years."

That's the budget trap, and here's what it tends to produce:

• A 74-question engagement survey launched in month one. The results go into a slide deck that lands in a folder, and no one acts on them.
• An org chart designed for the company you'll be in 2031, complete with a VP of Culture you can't afford.
• Confident answers pasted from a chatbot that sound great and are wrong for your province.
• "Wellness Wednesdays" launched while two of your managers are in a cold war over who owns the roadmap.

It's not their fault, because it's inexperience doing its best with copy-paste HR. At minimum, you've added a direct report who needs your judgment on every hard call. At worst, they move you backwards, and the best people on your team notice before you do.

Then there's the second half of the question: who manages your HR leader? If the honest answer is "me," you didn't remove HR from your plate. You added someone to develop, review, and coach, on top of everything else.

This isn't a knock on early-career HR pros, it just isn’t the role that growth-stage founders need.

What if your growth plan is outrunning your managers?

If your growth plan is outrunning your managers, you need senior HR help now, whether or not you have a full-time HR job. Managers and systems are what turn a growth plan into hit targets, and they take an experienced hand to build.

Picture your company as a house and you started with a cosy two-bedroom cottage: five people, one kitchen table, every decision made over coffee. Now your plan says add three floors this year.

Your managers are the load-bearing walls. Your people systems (hiring, onboarding, performance, career paths) are the frame. You can't stack floors on drywall and good intentions. Somebody has to reinforce the structure while you build, without evacuating the house.

This is where a senior builder who shows up regularly, knows the blueprint and makes sure every floor holds is invaluable.

A fractional HR partner is not a template library or an advice hotline. A senior HR professional who works inside your business part-time and does three things:

1. Learns the blueprint. Your revenue targets, the teams you're adding, the leaders you'll need in 18 months.
2. Builds the frame. People systems designed for your company, installed in focused sprints, not copied from someone else's.
3. Strengthens the walls. Coaches your managers until they're difference makers: people who set expectations, give feedback and solve problems without walking them into your office.

This is the part of HR that moves revenue, and the research backs it. 

Gallup finds that managers account for 70% of the variance in team engagement, and its meta-analysis of more than 183,000 business units found that teams in the top quartile of engagement are 23% more profitable than those in the bottom quartile. 

Your managers have the biggest impact on your profit margin.

A junior hire, or a COO wearing one more hat, hasn't built it before and you’re paying for them to learn in more ways than one.

At what size should a company hire its first HR person?

There's no magic headcount for when a company needs to invest in HR, but HR help usually pays serious dividends between 20 and 30 employees. Castle HR sees HR start taking over founders' calendars once a team crosses about 20 people, and the average Castle client signs at 29.2 employees.

Why 29.2? Because founders keep going, thinking they can just do what got them here, but that's when the kitchen-table company stops working. What got you here won’t get you there is a classic business lesson. You now have managers who've never managed, you are no longer hiring "a friend of a friend," and everything is still falling on your plate. 

But "we need HR help" and "we need a full-time HR leader" are two different moments, often years apart. Here's how they usually stack up:

Headcount is the clue as a 25-person company doubling this year may need more senior HR help than a 60-person company holding steady.

So what happens after companies bring in help at that stage? According to Castle HR's client data, the average client starts with 29.2 employees and reaches 53.6 two years later. 

Some clients more than doubled while others held headcount steady and became far more profitable instead, getting leaner and meaner rather than simply bigger. Either way, they grew without making a panic hire.

What does life look like once you make the right call?

Once the right HR model is in place, the founder stops being the bottleneck and becomes the builder again. Managers handle their teams, the people systems run without you, and your time goes back to growth and to the life you started the company for.

A founder who stood at this exact fork

In December 2023, Shoplogix, a Canadian software company, stood exactly at this fork. It had 35 people and a CEO, Carlos Midence, handling recruiting, onboarding, benefits, employee relations and manager questions himself, while expanding internationally.

Instead of proposing to a full-time hire, Shoplogix brought in Castle HR. Kathryn Edwards, a dedicated senior HR professional, met Carlos weekly, coached his managers and built the people systems around the company's growth goals. Two and a half years later, Shoplogix had grown to 70 people and more than doubled its revenue, and Castle HR's work had grown into leadership succession and acquisition-related HR, all without an internal HR department.

"Two and a half years in, HR just isn't something I worry about anymore." — Carlos Midence, CEO, Shoplogix

Now imagine your own company a year from now.

Your one-on-ones are different now because managers walk in with solutions, not escalations. "I handled it" has quietly become the most common phrase in your company, and you didn't even notice.

And then the good part.

You're on the dock at golden hour, phone face-down on the cedar, watching the loon do absolutely nothing urgent. You're in the front row at the championship game, and you see the winning goal with your own eyes instead of a replay in a group chat. You're in seat 2A to Lisbon, deciding between the champagne and the second champagne.

And if your company is ready for a full-time HR leader by then? Even better.

That's the shift this decision buys you: from you being the bottleneck everyone waits on to the brilliant leader everyone follows.

Are you ready for that future? Book your HR Escape Plan call → and let’s talk about your goals and how to get you there.

Why do growth-stage founders choose Castle HR as the bridge?

Growth-stage founders choose Castle HR because it gives them a senior HR partner now and a company that's ready for an in-house HR leader later. Castle HR works only with growth-stage companies and has done this for more than 250 since 2019.

We know this fork in the road well. We've sat with founders who were one bad night away from posting "HR Manager, start ASAP," and with founders who'd already hired and were quietly wondering how to undo it. 

We only hire senior HR professionals, and our team averages over 20 years of experience. 

The results we get are clear as 60+ Castle HR clients have made The Globe and Mail's list of Canada's fastest-growing companies, and founders rate us 4.9 stars on Google.
