Staff augmentation gives you skilled people you manage, billed by the hour. With managed services you hand a provider a defined outcome and pay a monthly fee, and running the team becomes their job.
RPO is for when you need to hire employees at volume and your recruiters can't keep up, while direct hire puts permanent people on your payroll.
So which one fits you? Six questions about your situation, plus a headcount check, usually settle it, and the scorer below asks all seven.

The Short Version
- If you need specialists fast for work with an end date, staff augmentation fits.
- If you want a result without managing the team behind it, look at managed services.
- A big hiring wave with too few recruiters points to RPO, and a capability you'll need for years points to direct hire.
- Most companies land on a mix, and the scorer below suggests one.
How the Four Models Compare
The biggest difference is who manages the daily work and who answers for the result.
Think of it like building a roster. Direct hire is the draft pick you develop for years, and MSH fills those seats through direct hire. On-demand staff augmentation is the veteran you sign for a playoff run.
Managed services hands a whole unit to another coaching staff, and enterprise RPO is a scouting department filling your roster under your name.
The table below shows how each one bills and what it costs to walk away.
If you only care about the recruiting side, RPO vs staffing firm vs in-house recruitment goes deeper.
The Sourcing Model Scorecard
Score six things about your situation from 1 to 5 and answer one headcount question. The scorecard ranks the four models by fit and names a hybrid when two finish within 12 points of each other.
The scorer can't see your budget or your politics. Bring the result to your leadership team as a starting point, then run each role through the free Sourcing Model Worksheet to see if it holds.
The Decision Matrix
Read across a row to see which way a high score pushes. A low score pushes the other way.
If you scored management bandwidth a 1 or 2, give managed services a hard look, since the provider that owns the outcome also carries the management load you don't have.
Worked Examples From the Scorer
Every situation below is a made-up composite run through the scorer to show how it behaves. Score each seat on its own, because one team often needs two models.
Those first two rows describe one team, where the lead seat comes out as a hire and the builder seats come out as staff augmentation, which is hybrid two below and the pattern MSH recommends for most companies standing up their first AI team.
Six Hybrids That Beat Picking One Model
Most teams end up mixing models. Most of the six below come from how MSH delivers work across contract staff, project teams and managed services, where clients often move up that ladder as the work matures and hire the people they can't afford to lose.
1. Contract-to-hire. Start someone on contract and convert them once the fit is proven. It works when you need speed now and expect the role to become permanent.
2. Hire the owner, borrow the builders. Hire one permanent lead who owns the capability, then add contract or nearshore engineers around them. This is the pattern for a new AI team, where you want the knowledge to live with an employee and the build capacity to flex.
3. Build then run. A project team builds it and a managed services team runs it. You get a dedicated build team without signing up for years, and a service level once things settle, provided the exit terms in the contract table below are in writing first.
4. Own the core, hand off the run. Plenty of companies keep the work that makes them different in-house with direct hires and move repeatable run work, like month-end dashboards or help desk tickets, into managed services.
5. RPO for the program, search for the leaders. Use RPO for a large wave of hires and a retained or direct hire search for the senior seats that need a closer, more discreet process. The executive search team at MSH runs those senior searches.
6. RPO for the core, contract for the peaks. Seasonal or project spikes are where this one earns its keep. Build the permanent team through RPO and cover the spikes with contract talent, so you never hire permanent people for temporary work.
If the scorer puts managed services and RPO close together, it tells you to split the work by role, since those two rarely compete for the same seat.
What Each Sourcing Model Costs
An agency placement fee, most often 20% of first-year salary, gets paid once and spreads across every year the person stays, which is why direct hire gets cheaper the longer you need the capability.
What a Full-Time Hire Costs
Benefits made up 30.0% of total compensation for private industry workers in June 2026, according to the Bureau of Labor Statistics (BLS Employer Costs for Employee Compensation, September 2026), so the number on the offer letter understates what an employee costs. Total compensation runs about 1.43 times wages before you count recruiting, equipment, space and management time (MSH calculation from the BLS figure). Treat that as the high end, since BLS counts paid leave as a benefit and an annual salary already includes it.
Take a senior engineer paid $200,000, which sits inside the $180,000 to $280,000 base range KORE1, a staffing firm, publishes for senior AI engineers (KORE1 salary guide, August 2026). That's about $96 an hour across 2,080 hours. Add benefits and it's roughly $137. Over six months the hire costs about $143,000 in loaded pay plus a $40,000 agency fee, around $183,000 in total. A contractor billed at $205 an hour, the middle of KORE1's published senior contract bill-rate band, costs about $213,000 for the same six months (MSH calculation using the BLS benefits share and the SIA fee).
On pay alone, the hire looks cheaper even over six months. Contract talent earns its premium in what that math leaves out. A permanent seat can take months to fill and longer to ramp, and when the need ends, closing a contract costs far less than unwinding a permanent role. As an MSH rule of thumb, if the work will outlast about a year and you can wait to fill it, hire. If you need output next month or the work has a clear end date, the contract premium is usually worth it.

Contract Terms Worth Asking For
The terms below decide what it costs to change your mind later, so settle them before you sign.
Keep a contractor long enough and treat them like an employee, and you can end up with misclassification or joint employer risk. The IRS explains how it decides who's an employee (IRS), and the US Department of Labor proposed a new joint employer rule in April 2026 that hadn't been finalized when this page was last checked in September 2026 (US DOL). Working through a staffing firm that employs the contractor on W-2 lowers that risk, and your counsel can tell you how much is left.
How Managed Services Pricing Works
Managed services are quoted as a monthly fee for a defined scope with service levels written into the contract, and the table below shows the usual ways that fee gets cut. Scope and hours of coverage set most of the price, so compare proposals on the same scope.
After scope, location moves the price most. The same scope run by an all-US team tends to cost more each month than a nearshore team working US hours, even when the output looks about the same. Putting US-based leads over a nearshore or offshore engineering bench brings the fee down, and MSH's ISO certified delivery centers keep security controls consistent wherever the engineers sit. See MSH's digital transformation managed services and DevOps managed services for how that works.
Where AI Teams Fit
AI seats are hard to place because the skills change fast and the work sits close to your core, and on the scorer those two factors pull in opposite directions. That's why most first AI teams end up with hybrid two.
Plenty of companies bring in outside help for AI, and the ones it works for decide before the contract which seats they'll own and which a partner covers until the permanent hires are in place. In RSM's 2025 survey of 966 US and Canadian middle-market leaders, 70% of firms using generative AI said they needed outside help to get the full value from it (RSM, June 2025).
If you're still deciding which AI roles to hire first, start with the AI engineer job description and scorecard templates. Contract AI talent comes through MSH's AI staff augmentation team, while build work sits with the AI implementation consulting and AI center of excellence consulting teams.
Frequently Asked Questions
What is the difference between staff augmentation and managed services? With staff augmentation you get skilled people who work under your direction, and you own the outcome. With managed services a provider takes on a defined function, manages its own team and is accountable for service levels. Staff augmentation is billed by the hour and managed services is usually a fixed monthly fee.
Is staff augmentation cheaper than hiring? Usually not on a monthly basis. Even after benefits (about 30% of total compensation per BLS) and a placement fee, a senior contractor often costs more than a hire over the same period. Staff augmentation earns its premium when you need someone next month and won't need them next year.
How much does RPO cost? Many RPO contracts combine a monthly management fee with a fee per hire, and some charge per hire only. Hard-to-fill roles and bigger volumes push the price up, and so does handing the provider more of the process. In MSH's experience, below roughly 15 roles a year the program fees tend to outweigh the savings.
What is the difference between staff augmentation and outsourcing? Staff augmentation adds people who take direction from your managers. Outsourcing, including managed services and project-based work, hands a defined piece of work to a provider that runs its own people. If your manager assigns their tasks every morning, you're augmenting. If you're reading the provider's service report at the end of the month, you've outsourced.
When should you use managed services instead of hiring? When the work repeats month after month and nobody on your team has time to manage it well. Month-end BI reporting and L1 and L2 support are common examples. If the work is core to your competitive advantage, keep it in-house anyway.
Can you combine staff augmentation and direct hire? Contract-to-hire is the simplest version, since you test fit before converting someone to an employee. Teams building something new often go further and put a permanent lead over a contract bench, so the knowledge stays in-house while the team size flexes with the work.
