The Question Every Business Owner Gets Wrong
Let's be honest, when a majority of entrepreneurs set out to develop their app, the first thing they search for online is "cost of developing an app." The better question to ask, the question that could mean saving thousands or even millions of pounds or dollars, is "who should build my mobile app?"
Should I engage mobile app developers working for an agency or freelance mobile app developers? Should I build my own mobile app development team?
That seems easy enough to answer. Not really.
A poor choice could waste your money, slow down your time-to-market strategy, and result in an app nobody wants. But a smart choice will not only speed up your journey to the market but also make it more cost-effective and successful.
Throughout my career, I witnessed these challenges being solved in various ways by early-stage businesses, mid-size firms, and even large corporations. In this article, I will discuss the statistics behind each option, the factors not often mentioned when choosing one, and what model works best for what type of company.
The Real Cost Breakdown: In-House vs Hiring Mobile App Developers
Before we get into opinions, let's talk about money. Because this is where most people get a nasty surprise.
What an In-House Team Actually Costs You
Having your own mobile application development team is tempting. You are in charge. You can discuss the details of the project directly with your employees every day.
But here's what that control actually costs you:
Salaries alone are just the beginning.
The average annual salary for a mid-level mobile app developer in the UK ranges from £45,000 to £70,000, while in the United States, the range extends to $90,000-$130,000 per year. Consider this amount multiplied by the number of required specialists; most likely, you'll need at least an iOS developer, an Android developer, a backend developer, a UI/UX designer, and a QA tester.
And so, without even writing one line of code, your annual expenditure on just wages is going to be estimated between £250,000 and £400,000.
And that's before you factor in:
- Recruitment costs — agency fees, job board listings, interviewing time (often 3–6 months to hire good talent)
- Onboarding and training — new developers need time to get up to speed with your systems and goals
- Employee benefits — pensions, health insurance, paid leave, sick pay
- Office space and equipment — desks, laptops, software licences, collaboration tools
- Management overhead — someone has to lead the team, review code, and run sprints
Adding up all these costs, you'll find yourself paying $500,000-$700,000 in the very first year of developing your application.
That's not a small investment. And it's a fixed cost — you're paying it whether the app is in full development or sitting idle between sprints.
What It Costs to Hire Mobile App Developers Externally?
And now let's consider another perspective. The way that agencies and dedicated developers charge you is quite different from the traditional methods.
Typically, companies that provide services to Hire Mobile App Developers offer flexible engagement models such as project-based or time and materials pricing approaches. With these models, you're charged according to your actual requirements and the time needed to complete them.
A well-scoped mobile app from a reputable mobile app development company typically costs:
- Simple app (basic features, one platform): $15,000–$40,000
- Mid-complexity app (custom features, iOS + Android): $40,000–$100,000
- Complex, enterprise-grade app: $100,000–$250,000+
Sure, the figures above seem rather high. However, this is where the crucial distinction lies – you only pay for one product once; not $500,000 annually just to have developers sitting idly around waiting for tasks.
And if you hire through a quality mobile app development company, you're also getting:
- A full team already assembled — developers, designers, testers, project managers
- No recruitment delays (you can often kick off within two to four weeks)
- Experience across dozens of app builds, meaning fewer costly mistakes
- Flexibility to pause, reduce, or increase scope based on your budget
The Hidden Costs Nobody Talks About
And this is where things get really interesting – the part where most "comparison" pieces fall apart entirely.
The Hidden Cost of In-House: Time to Hire
It is difficult to find top-quality mobile developers, especially now when the competition is high, and the best developers have many offers. So, expect to wait at least three to six months while looking for an employee. During this period, no work will be done, and other businesses may get ahead of you. It has a direct impact on your budget.
The Hidden Cost of In-House: Knowledge Gaps
If you lack enough technical knowledge in your organization, chances are that you will not make the right decision regarding the technology stack. Poor choice of infrastructure or missing QA testing may result in an application that needs to be re-written after 12 months of launch. Believe me, I have witnessed such mistakes among funded start-ups, and it was quite an unpleasant experience.
The Hidden Cost of External: Choosing the Wrong Partner
Every Mobile App Development Company differs from one another in terms of expertise, pricing models, technologies, industry experience, and development approach.An inexpensive software vendor that overpromises and does not deliver on its promises can cost you even more than hiring an in-house developer. In other words, choosing the right partner is crucially important for successful project implementation.
Look for a company that has a clear discovery process, shows you past work, and gives you a detailed project roadmap before taking your money.
When Hiring Mobile App Developers Makes More Sense?
Let's get practical. Hiring externally tends to be the smarter financial and strategic choice when:
You're a startup or early-stage business.
You have to prove your concept in the first quarter; there’s no point in six months of hiring and training. Launching your MVP (minimum viable product) within weeks can make or break a startup.
You have a defined, time-bound project.
When it comes down to developing a custom app within a certain timeframe, a team that already knows how to develop such products will always outperform an internal team that is just beginning to get comfortable working together.
You want access to a breadth of experience.
An excellent mobile app development agency has developed apps in several industries like retail, healthcare, financial services, logistics. This broad industry knowledge implies they know how to resolve issues you may not even be aware of.
Your app needs to work across iOS and Android.
It is costly to maintain expertise on both platforms in-house. The external team will have professionals on both platforms.
Your budget is under $500,000 for the first year.
Below this point, in-house development does not make economic sense unless your application is a core product for which you plan years of development ahead.
When an In-House Team Makes More Sense
To be fair, there are situations where building internally is the right call:
Your app is your entire product, and it needs constant daily updates.
When your company is completely focused on the application being developed, which is usually the case with startups in fintech or SaaS sectors, having an in-house team that shares your values may benefit you in the long run.
You have serious compliance or security requirements.
There are some companies operating in highly regulated sectors that feel it is necessary to have all the development done in-house due to issues with data sovereignty and compliance (though agencies can often comply as well).
You're planning 3–5 years of intensive, full-time development.
As we mentioned before, there is some point in the project’s scale and duration when the costs of internal development will balance out those for outsourcing the job.
What About Quality? Does External Mean Inferior?
This is the biggest myth in the industry, and it needs to be addressed head-on.
The idea that the developers you hire will be more interested in your product than those you employ internally is just plain wrong. Good developers – regardless of where they're located – are passionate about what they do. It doesn't matter if the team works with you on-site or remotely; it's all about the quality of the team and their processes.
However, it's essential that you have the means of communication, collaboration, and tracking. Hiring mobile app developers via the services of a reputable agency implies being able to hold daily stand-ups, perform sprint reviews, access the necessary tracking tools, and have constant communication channels open.
Not receiving these services, which are critical when working with your mobile app developers, shouldn't be taken as an argument for hiring them in-house – rather, it should ring some alarm bells in your head.
Questions to Ask Before You Decide
Here's a simple mental checklist to help you figure out which route is right for you:
- Do I need this app live within the next six months?
- Is my annual budget for app development under £500,000?
- Do I have a technical co-founder or CTO who can lead an internal team?
- Is this a one-time build or an ongoing product that will need constant updates for years?
- Am I in a regulated industry with strict data handling requirements?
If you answered yes to the first two and no to the others, hiring externally is almost certainly the smarter financial decision.
Conclusion:
There's always an appeal in having your own team that develops products from scratch. It makes one feel like the owner and makes them work hand in hand with others. In some cases, this kind of approach brings good results.
However, in most cases, when we consider startups, growth companies, and even SMEs, it makes more sense to use another approach, since it would be less costly and risky. In this case, one can find mobile app developers in a mobile app development company and save money on salaries, office equipment, and other resources.
Using a mobile app development company to hire mobile app developers enables you to enjoy quick services, flexibility, and an entire team of specialists – often at a much lower cost than hiring internally.
