Key Takeaways
- The three models sit on a spectrum of control versus operational load, not a ranking of good to bad.
- At 20 people, the right model shifts based on how permanent the function is, how exposed it is to compliance risk, and how much internal management bandwidth you have to direct the work.
- Dedicated teams and staff leasing both route employment through the provider. The real difference between them is depth of embeddedness and long-term intent, not who carries employment liability.
You have approved headcount for a 20-person back-office function, and now someone must decide how to build it. Three models are usually on the table: a dedicated team, staff augmentation, or staff leasing.
Each one solves a different problem, and the fit depends on how permanent the function is, how much daily management you want to carry, and how much compliance exposure you are willing to hold.
This piece scores dedicated team vs. staff augmentation vs. staff leasing against that exact scenario, on cost, control, and risk, so the comparison reflects the decision you are making. At this size, a wrong pick is a rebuild, not a minor course correction.
The Scenario: A 20-Person Back Office at a Growth-Stage Company
Let us picture a finance organization that needs to stand up 20 roles across functions like accounts payable, accounts receivable, general accounting, or revenue cycle support.
The CFO approving this build is not always the person who will run it day to day. That person needs a decision that holds up in a budget review six months from now, not just one that solves this quarter’s staffing gap.
At this scale, the stakes change. A model mismatch involving two or three people is an inconvenience. A model mismatch across 20 roles means retraining, re-contracting, or absorbing a management burden nobody planned for.
This scenario assumes a function that is expected to run for at least 18 to 24 months, with a mix of routine processing work and some judgment-based tasks that require consistency across the team.
Three Models, One Axis: Control vs. Operational Load
What a Dedicated Team Is
A dedicated team is built exclusively for one client. The professionals on it work only for you, follow your processes, and operate as a long-term extension of your organization. You direct daily work and set priorities, while the provider handles recruiting, HR, payroll, compliance, and facilities underneath.
This model fits functions you expect to run indefinitely and want built with continuity in mind. For a deeper breakdown of how this compares specifically to staff augmentation, see Offshore Staff Augmentation vs. Dedicated Team: Which Fits You?.
What Staff Augmentation Is
Staff augmentation adds individual contributors to a team you already run. You manage their work the same way you manage anyone on your existing team, while the provider sources and employs the talent.
This model is built for filling a defined gap, not for standing up a full function from scratch. It works best when you have an existing management structure in place and need to add capacity within it.
What Staff Leasing Is
Staff leasing places provider-employed staff with your company for a contracted period. The provider is responsible for recruiting, hiring, and managing employment, while you assign day-to-day work.
It is a longstanding, legally established practice, particularly in markets like the Philippines, and tends to carry more defined contractual terms around duration than a dedicated team arrangement.

Scoring the 20-Person Scenario: Cost, Control, Risk
| Model | Cost | Control | Risk |
| Dedicated Team | Medium, cost predictability improves as the team scales toward 20 | High. Full daily direction, embedded processes, long-term continuity | Low to Medium. Higher upfront setup, but lower continuity risk over an 18-to-24-month horizon |
| Staff Augmentation | Medium, cost scales per contributor added | High for individual roles, but coordination load increases as headcount grows | Medium. Works well for a handful of roles, strains at 20 without added internal management structure |
| Staff Leasing | Lower administrative overhead, cost tied to contract terms | Medium. Day-to-day direction sits with the client, but the arrangement is often framed around contract duration rather than long-term embedding | Medium. Compliance exposure depends heavily on jurisdiction and contract structure |
At 20 roles, cost differences between the models tend to narrow. The more decisive variables are control (meaning how much daily direction you want to exercise) and risk (meaning how much compliance and continuity exposure you are willing to carry).
Where Each Model Breaks Down at This Size
Staff augmentation fills a defined gap, not to stand up 20 roles at once. Stretched across a full function, it can create a management burden that can exceed the internal budget. Someone on the client side must coordinate, onboard, and manage every contributor individually, and that coordination cost compounds with headcount.
Staff leasing works well when contract terms and duration are clearly defined, but at 20 people, team cohesion starts to matter more than it did on a smaller scale. A leasing arrangement without attention to culture fit and continuity can leave a client with a group of competent individuals who never function as a unit.
A dedicated team built for a function that turns out to be temporary creates the opposite problem. The upfront investment in building long-term infrastructure does not pay off if the function is disbanded in a year, and unwinding a dedicated team is a heavier lift than letting a staff augmentation contract lapse.
A Simple Decision Framework
Before choosing a model, walk through these questions:
- Is this function permanent or project-based? Permanence favors a dedicated team. A defined project favors staff augmentation.
- How much internal management bandwidth exists to direct day-to-day work? Limited bandwidth favors a model with more embedded process support.
- What is the compliance profile of the work? Higher regulatory exposure favors models with stronger built-in continuity and process discipline.
- How much does institutional knowledge matter for this function? Functions where knowledge retention drives quality favor long-term, embedded arrangements over shorter contract structures.
Choosing the Right Model
The right choice among the three models is the one that matches your function’s permanence, internal management capacity, and compliance exposure. For a 20-person back office expected to run for the long term, that match matters more than it would at a smaller scale, because the cost of unwinding the wrong choice grows with headcount.
Connext builds and manages teams under all three models through a co-management approach, where staffed professionals are fully embedded in your team while Connext handles the employment infrastructure behind them.
Whichever model your framework points to, the execution question is the same: who can build and run it at 20 or more person scale without losing the control you need.

Frequently Asked Questions
Yes, though the transition works best when planned rather than reactive. Moving from staff augmentation to a dedicated team typically involves formalizing existing contributors into a permanent structure, which is usually smoother than starting a new build from scratch.
Yes. Staff leasing is structured around the provider holding local employment, which allows a U.S. company to engage leased staff without registering a foreign entity or navigating local labor law directly.
All three route formal employment through the provider, but the degree of client-side direction affects how co-employment risk is assessed in each jurisdiction. Dedicated teams and staff leasing both keep a clear line between employer of record and day-to-day direction, while staff augmentation can blur that line if the client’s management involvement extends too far into HR-adjacent decisions.
Dedicated team structures are built with continuity in mind, so knowledge transfer processes and documentation standards are typically part of the initial setup, reducing the impact of any single departure.
Staff leasing can work at nearly any size, but the administrative simplicity it offers becomes less of a deciding factor as headcount grows and coordination complexity increases regardless of model.
