Hire in-house when the need is permanent, predictable and central to how your agency grows. Bring in dedicated developers when demand is growing but uncertain, tied to particular clients, or needed sooner than recruitment allows. The deciding question is simple: will this exact need still exist in twelve months?
As agencies grow, new projects, bigger retainers and unexpected team changes usually lead to the same conclusion: “We need to hire.” Sometimes that's right. Often it's a permanent answer to a temporary problem.
This guide sets out the real cost of a hire, compares an in-house developer with dedicated developers and freelancers, and gives you five questions to answer before you post the job ad.

Hire in-house when:
The work is permanent and predictable.The skill is core to your agency's offer.You're ready to recruit, manage and develop that person for years.Use dedicated developers when:
Demand is growing, but you can't promise it'll last.The need is tied to a specific client, project or skill.You need capacity in weeks, not months.A full-time hire costs far more than the salary on the job ad. Before comparing it with any alternative, add up everything it actually involves:
Recruitment: agency fees or your own time on job ads, screening and interviews.Notice periods: senior developers often have one to three months' notice before they can start.Employment costs: in the UK, employer National Insurance and pension contributions; in the US, payroll taxes and benefits.Equipment and software: hardware, licences and tools.Ramp-up: weeks or months before a new developer works at full speed on your stack and clients.Management time: one-to-ones, reviews, training and career development.The fixed commitment: if the workload that justified the hire drops six months later, the cost doesn't drop with it.None of this makes hiring wrong. It makes it the right answer to a specific kind of problem, not the default answer to every capacity challenge.

| In-house hire | Dedicated developers | Freelancer | |
|---|---|---|---|
| Time to start | Months (recruitment + notice) | Typically days to a few weeks | Days, if they're available |
| Upfront cost | Recruitment, equipment, onboarding | Low | Low |
| Ongoing cost | Fixed salary and employment costs | Monthly fee for agreed capacity | Day or hourly rate |
| Scaling down | Slow and costly | Adjust capacity with notice | Easy, but you lose them |
| Management load | Highest: you manage everything | Shared: you set priorities, the partner handles HR | You manage the work; no cover |
| If someone leaves | You recruit again | The partner replaces and hands over | Work stops until you find someone |
| Holiday and sickness cover | Your problem | Usually handled by the partner | None |
| Best for | Permanent, core roles | Growing or uncertain demand | Short, well-defined tasks |
The right choice depends on how certain and how permanent the need is, not on comparing an hourly rate with a salary.
Hiring is often the right choice when:
The demand is permanent and predictable.The skill is central to your agency's long-term growth.You're confident the workload will stay consistent.You're ready to invest in building and managing an in-house team.In these situations, hiring isn't just an expense; it's an investment in your agency's future.
Not every capacity challenge calls for a permanent hire. More often, agencies are in situations like these:
A client has expanded the scope of a project.You need specialist expertise for one engagement, not every engagement.Demand is growing, but future workload is still uncertain.You need extra delivery capacity quickly, without waiting through recruitment.Here, dedicated developers let you grow without a long-term commitment that may not match your future needs. Instead of hiring permanently, you extend your team with experienced developers who work alongside your people and processes.
The real question isn't “Can we afford to hire?” It's “Will this exact need still exist in twelve months?” If the honest answer is “probably, but we're not certain”, that's worth paying attention to.
Is this need permanent, or tied to a specific client or project?Will we need this skill on every project, or only occasionally?Could we comfortably carry the salary, employment costs and management time if demand slowed?How long can we realistically wait for someone to be recruited, serve notice and get up to speed?If this person left in six months, would we replace them immediately, or quietly adjust our capacity?If two or more of these give you pause, try dedicated developers before you expand your permanent team. You can always hire later, once the demand has proved itself.
It doesn't have to be one or the other. Many agencies keep a small in-house core (the people who own client relationships, architecture and quality) and add dedicated developers for delivery peaks, specialist stacks or clients with uncertain futures.
That way your permanent team stays sized for your baseline workload, and the variable part of your capacity stays variable. When a stream of work proves itself over a year or more, that's often the moment to hire for it.
Dedicated developers aren't outsourced project work. They're experienced developers, or a whole team, who become an extension of the way your agency already works.
They work in your tools.They join your stand-ups.They follow your priorities and your process.They collaborate directly with your in-house team.The difference is that you get extra delivery capacity without the recruitment timeline, the long onboarding or the long-term employment commitment.
At I-Genesys this usually means one of two models: Dedicated Developers, an ongoing extension of your team, or Reserved Engineering Capacity, flexible capacity you draw on as needed. Which one fits depends on how predictable your demand is.
Hiring for one client's project. When that client's budget changes, you're left with a fixed cost and no work to fill it.Comparing an hourly rate with a salary. The salary is only part of what a hire costs; the rate is close to the full cost of dedicated capacity.Bringing in external developers but keeping them outside your process. Without access to your tools, stand-ups and standards, you get a supplier, not extra capacity.Choosing a partner on price alone. The cheapest option is rarely the one that protects your client relationships.We cover what to look for in how to choose a white-label development partner, and what goes wrong in why most outsourcing relationships fail.
It depends on how long and how steadily you need them. For permanent, full-time work, an in-house hire is usually cheaper over several years. For growing, uncertain or client-specific demand, dedicated developers usually cost less overall, because you avoid recruitment, ramp-up and the cost of carrying someone when work slows.
Typically within days to a few weeks, compared with the months a permanent hire takes once you add recruitment and notice periods.
They should. A good dedicated developer joins your stand-ups, works in your project management and code repositories, and follows your standards, so they work like part of your team.
With project outsourcing, you hand over a defined scope and get a finished result. With dedicated developers, you keep control of priorities day to day and the developers work as an extension of your team, which suits ongoing or changing work.
With an in-house hire, the cost stays the same. With dedicated developers, you can usually reduce capacity with notice, which is one of the main reasons agencies use them for uncertain demand.
