A few months ago, someone called me with a painful story. A year earlier, they had hired a "very cheap team" to build their app -- paid 4,000 EUR, expected delivery in 2 months. A year later? No app. No money. And now they were looking for another developer to start everything from scratch.
I hear stories like this at least a couple of times per month. And the root causes are always the same: they chose based on price, did not ask the right questions, and did not sign a proper contract.
This article is here so that does not happen to you. I will walk you through the three main options, what each costs, and how to tell a good developer from one who just talks a great game.
Three Options: Freelancer, Agency, Offshore
When you are looking for someone to build your app, you essentially have three paths. Each has its own logic, and none is universally the best.
Freelancer
A single person who does everything -- from design to development. Or specializes in one area and subcontracts the rest. The freelancer market in Europe is large and competitive, with plenty of highly skilled professionals who chose to go independent.
Freelancer Advantages
- Price -- typically 20-40% cheaper than an agency, since there is no office, management, or marketing overhead
- Direct communication -- you talk to the person writing the code. No intermediaries
- Flexibility -- can adapt to your schedule, work evenings or weekends if needed
- Fast start -- no need to coordinate with 5 people. You agree -- and they start
Freelancer Risks
- Bus factor = 1 -- if they get sick, go on holiday, or simply vanish -- your project stalls
- Limited expertise -- rarely is someone equally strong in design, backend, frontend, and testing. There will be a weak spot
- Post-project support -- after the project, you may lose them. They move on to the next client, and your app gets no attention
- No guarantees -- without a contract (and many people skip it), you have zero legal protection
When to choose a freelancer: Smaller projects under 10,000 EUR. When you know and trust the specific person. When the project is straightforward and does not require multiple specialists simultaneously.
Local Agency
A team of 5-30 people in your region. Typically includes a project manager, designer, several developers, and a tester. They work with established processes, have a portfolio, and are a registered company.
Agency Advantages
- Team -- each person does what they do best. The designer designs, the developer codes, the tester tests
- Processes -- sprints, regular demos, documentation. You see progress every week
- Continuity -- if one person leaves, they are replaced. The project does not stop
- Legal security -- contracts, warranties, SLA after the project. If something goes wrong, you have someone to hold accountable
- Portfolio -- you can see actual working projects and speak with previous clients
Agency Risks
- Price -- 30-50% more expensive than a freelancer. You pay for the entire team and processes
- Bureaucracy -- sometimes slower to start because of contract negotiations, resource planning, and management approvals
- Attention -- if your project is small (5,000 EUR) and the agency has a 50,000 EUR project, guess which one gets more attention
When to choose an agency: Projects over 10,000 EUR. When the app is business-critical. When you need multiple specialists (design + dev + testing). When you want post-project support and warranties.
Offshore Team
A team abroad -- typically in Ukraine, India, the Philippines, or South America. Found through platforms like Upwork and Toptal, or through direct outreach.
| Factor | Freelancer (EU) | Agency (EU) | Offshore |
|---|---|---|---|
| Hourly rate | 30-60 EUR | 50-90 EUR | 15-40 EUR |
| Simple app (cost) | 5,000 - 12,000 EUR | 8,000 - 18,000 EUR | 3,000 - 8,000 EUR |
| Medium app (cost) | 12,000 - 25,000 EUR | 18,000 - 40,000 EUR | 8,000 - 20,000 EUR |
| Communication | Direct, native language | Via PM, native language | English, often challenging |
| Time zone | Same | Same | +2 to +8 hours difference |
| Legal protection | EU law (if contract exists) | EU law, strong contract | Complex -- different jurisdiction |
My experience with offshore teams is mixed. I have seen excellent Ukrainian developers who deliver outstanding work. But I have also seen projects from India where a 3,000 EUR project turned into 12,000 EUR because everything had to be rewritten.
When to choose offshore: When you have technical knowledge and can quality-check the work yourself. When the project is standard (e-shop, informational site) and does not require much communication. When the budget is very tight and you understand the risks.
Red Flags -- How to Spot a Bad Developer
Over the years, I have compiled a list of warning signs. If you spot 2 or more of these -- walk away.
8 Warning Signs
- No portfolio. Or the portfolio exists but the projects do not work -- links lead to 404 pages. If someone cannot show a single working project, something is wrong.
- Too-cheap pricing. If everyone quotes 10,000 EUR and one quotes 2,000 EUR, it is not a genius who works faster. It is someone who either did not understand the project or does not plan to finish it.
- Promising timelines without seeing requirements. "We'll do it in a month, no problem" -- without asking a single question about features. A professional never gives a timeline without a detailed brief. More on realistic timelines in our article about how long it takes to build an app.
- Refusing to sign a contract. "Why do we need a contract, we'll work things out." Sure -- as long as everything is going well. When problems start, a contract is the only thing protecting you.
- No mention of post-launch support. If the developer does not even bring up what happens after delivery, they are planning to hand over and disappear. An app needs maintenance like a car needs servicing.
- Vague answers about source code ownership. "Who owns the code?" -- if you do not get a clear answer to this, you could end up without your own app's code. And when you want to switch developers, you start from zero.
- Asking for 100% upfront payment. Standard practice is 30-50% upfront, the rest in instalments tied to milestones. If they want the full amount before starting, the risk is enormous.
- Over-promising. "We'll add AI, blockchain, and VR -- for 5,000 EUR." When someone promises everything, they usually deliver nothing.
7 Questions You Must Ask Before Signing
Before signing a contract, before paying a deposit -- ask these questions. And pay attention not just to the answer, but to how they react. A professional answers calmly and specifically. An amateur deflects.
- What similar projects have you built? Ask to see working apps. Not screenshots -- working apps. Download them, try them. If they do not work well, yours will not either.
- What tech stack will you use? You do not need to understand every detail, but the answer should be specific: "React Native + Node.js + PostgreSQL" -- good. "We'll see what fits best" -- bad.
- Who will own the source code? The correct answer: "You, 100%, after final payment." Anything else is a red flag.
- What happens if the project runs late? A good developer says: "We'll define deadlines and consequences in the contract." A bad one: "We never run late." (Spoiler: everyone runs late sometimes.)
- What does post-launch support look like? How much does it cost? What is the response time? Is there an SLA? If the answer is "we'll figure it out" -- there is no plan.
- How do you manage communication? How often are demos? Will I have access to a task board? Will I see progress in real-time? Good developers use Jira, Trello, Asana, or similar tools.
- What if I don't like the result? How many iterations are included in the price? When do additional charges start? The clearer this is upfront, the fewer conflicts later.
Contract Essentials
Far too many businesses commission apps without a contract. "They seem trustworthy, we shook on it." And then they reach out to me when everything falls apart.
What Must Be in the Contract
- Detailed scope of work -- the more precisely described, the fewer misunderstandings
- Timeline with specific dates and milestones -- not "about 2-3 months" but actual dates
- Price and payment schedule -- 30% deposit, 30% after design, 30% after development, 10% after acceptance
- Source code ownership -- transfers to client after final payment
- Warranty period -- minimum 3 months, during which bugs are fixed for free
- Confidentiality (NDA) -- especially if the project has unique business logic or proprietary features
- Termination conditions -- what happens if either party wants out. How much is refunded, what do you keep
Yes, having a lawyer draft a proper contract costs 200-500 EUR. But it can save you 5,000-15,000 EUR if things go sideways.
How to Evaluate a Portfolio
A portfolio is the first thing I look at when someone asks me "which developer should I choose?" And I do not evaluate pretty screenshots -- I look for specific things.
Download and Try It
If a developer says "we built app X" -- go to Google Play or the App Store, download it, and use it for 10 minutes. Does it load quickly? Is the navigation intuitive? Are there obvious bugs? If you find 3 issues in 10 minutes, think about whether you want that quality for your project.
Evaluate the Design and UX
Does the app look modern? Is the navigation logical? Are the fonts readable? If the portfolio projects look like they were designed in 2018, the developer either does not work with a designer or does not care about design.
Talk to Previous Clients
A good developer will happily provide 2-3 references from previous clients. Call them and ask: did they meet deadlines? Was communication good? Do you still work together after the project? Client testimonials tell you more than any portfolio.
Where to Find App Developers
Here are the channels that actually work:
- LinkedIn -- the largest professional network. Search "mobile developer" filtered by location and experience
- Clutch.co -- an agency rating platform with verified reviews and case studies
- Referrals -- ask business contacts who built their app. The best developers often do not advertise -- clients find them through word of mouth
- Startup communities -- tech hubs and coworking spaces are full of developers looking for projects
- Upwork / Toptal -- for finding offshore or remote talent, with built-in review systems
Why the Cheapest Option Often Costs the Most
Let me return to the person I mentioned at the start. They paid 4,000 EUR to a "cheap" developer. A year later -- no app, no money. Now they are paying 14,000 EUR to a proper agency to build everything from scratch.
Total cost: 18,000 EUR + one year of lost time.
If they had chosen the agency from the start, they would have paid 12,000-15,000 EUR and had a working app 10 months ago.
That is the paradox. The cheapest quote on paper can be the most expensive in reality. Not always, but often enough that it is not worth the gamble.
My Personal Recommendation
If your budget allows it, aim for the mid-range. Not the cheapest, not the most expensive. The cheapest often will not finish the project. The most expensive does not necessarily deliver better work -- they just have a bigger office and fancier coffee.
The sweet spot: 40-70 EUR/hour for a freelancer, 60-90 EUR/hour for an agency. At this price point, you are working with professionals who value their reputation.
Frequently Asked Questions (FAQ)
Final Thoughts
Do not choose a developer the way you buy potatoes -- by price per kilogram. Choose the way you choose a surgeon -- by experience, references, and trust.
And trust your gut. If after the first conversation something feels off -- if they are promising too much or asking too few questions -- it probably is. A good developer asks more questions than they answer in the first meeting. They want to understand your business, not sell their service.
