Every service is built by VirtuoLab itself, with a fixed price agreed in advance.

How do you choose between a website, a web app, a mobile app and SaaS?

The choice between a website, a web app, a mobile app and SaaS is a question of what users need to do. A website fits when visitors mainly read, compare and get in touch, as on a business website or a webshop. A web app fits when users log in and do work in the browser, such as planning, approving or managing data. A mobile app fits when users need the product daily on a phone, with push notifications or the camera. SaaS is a web app sold to many customers on subscription, with separate accounts and recurring payments. In practice, a web app built with Next.js also works on phones, so a separate mobile app can often wait. Additionally, every option needs a mobile layout: phones generated about 65% of web traffic in the Netherlands, according to StatCounter data for September 2026. A business website costs €2,000 to €8,000 as an indication. In the free intake call, VirtuoLab helps pick the right option.

What happens after VirtuoLab delivers a project?

After delivery, a VirtuoLab project is the property of the client: the client owns the source code and the data. Launch and support is the final step of every project. First, VirtuoLab puts the software live and trains the future users. Second, support continues after launch, on working days from Monday to Friday between 09:00 and 18:00. Questions and issues can be reported through the support desk on virtuolab.dev, by email or by phone. Third, new features can be added later as further development. Running costs below are indications for 2026. For example, hosting an app backend typically costs €50 to €500 per month. For KPI dashboards built with Power BI or React, hosting, monitoring and further development cost €150 to €750 per month, and an extra KPI after launch costs €250 to €1,500. Apple charges €99 per year for the App Store, and Google charges €25 once for Google Play. VirtuoLab does not offer round-the-clock support, because VirtuoLab is a one-person business.

Which technology does VirtuoLab use, and why?

The standard stack at VirtuoLab is React, Next.js, TypeScript, Node.js and PostgreSQL, and the reasons are practical. First, the tools are widely used and open source, so another developer can continue the code later and the client is never locked in. About 45% of respondents used React and about 56% used PostgreSQL, according to Stack Overflow's Developer Survey 2025. Second, TypeScript catches many errors before the software reaches users. Third, Next.js can render pages on the server, so Google and AI crawlers receive the full text without running JavaScript. The website virtuolab.dev itself is built with Next.js for the same reason. Mobile apps are built with React Native or Flutter, or with Swift for native iOS. Python, MongoDB, GraphQL, Tailwind, Docker and AWS complete the toolkit where a project needs them. Dashboards are built in Power BI or as a custom React app, and plugins run on WordPress, WooCommerce or Shopify. In practice, the project decides the final choice, not a fixed preference of the developer.

How does a quote from VirtuoLab come about?

A quote from VirtuoLab is a fixed price with a schedule, agreed before any code is written. The process has three steps. First, the client books a free intake call, online or on location in the Drechtsteden or Rotterdam. During the call, VirtuoLab maps out goals, wishes, users, existing systems and budget. Second, VirtuoLab sketches an approach free of charge. Third, the client receives the quote with a fixed price and a planning. The quote form on virtuolab.dev is another way to start, for example for a business website with 8 pages and a clear brief. The price ranges on the website give a first idea for 2026: a simple web app built with Next.js costs €5,000 to €10,000, and a business website costs €2,000 to €8,000. Because the price is fixed up front, the client knows the total cost of the build before work starts. Mustafa Kose answers questions about the quote directly, without an account manager in between.

What does SEO and GEO as a service include?

SEO and GEO at VirtuoLab is a service making a website easier to find in Google and in AI assistants such as ChatGPT, Perplexity, Gemini and Claude. SEO aims for a high position in search results. GEO, short for generative engine optimisation, aims for a citation inside the AI answer itself. In a study by Pew Research Center, 18% of Google searches produced an AI summary in March 2025. The service has four parts. First, the technology: AI crawlers get access, and the site gets an llms.txt file and structured data. Second, the entity: one consistent business description across the web, for example on LinkedIn and in Google Business Profile. Third, the content: pages around customer questions, with the answer in the first sentence. Finally, the measurement: a fixed set of questions, tested every month with ChatGPT and other assistants, plus a monthly report. The goal: getting mentioned faster and more often in AI answers. The price follows after an intake call and a baseline measurement.

Frequently Asked Questions

What does a custom web application cost?

The cost of a custom web application at VirtuoLab is a fixed price between €5,000 and €50,000 or more, depending on complexity. The indications below apply to 2026. First, a simple web app built with Next.js costs €5,000 to €10,000 and takes 3 to 6 weeks. Second, a medium-sized web app costs €10,000 to €25,000 and takes 6 to 12 weeks. Third, a complex web app or SaaS platform costs €25,000 to €50,000 and takes 12 to 24 weeks. Finally, an enterprise platform starts at €50,000, with a lead time of 24 weeks or more. The price depends on the number of features, user roles and links with other systems, for example accounting software or a CRM. User roles need careful access control: broken access control ranks first in the OWASP Top 10 of 2025 and appeared in 100% of tested applications, according to OWASP. Every project gets a fixed price before any code is written, set by VirtuoLab after a free intake call.

How long does it take to develop an app?

The lead time for an app at VirtuoLab is anywhere from 1 week to more than 24 weeks, depending on the type of project. All lead times are indications for 2026. For example, a landing page with a waiting list for an MVP takes 1 to 2 weeks, and a simple web app takes 3 to 6 weeks. An MVP with user login takes 6 to 10 weeks. A cross-platform mobile MVP for iOS and Android, built with React Native or Flutter, takes 8 to 12 weeks. A complex web app or SaaS platform takes 12 to 24 weeks. Additionally, the app stores add time at launch. App Review typically handles at least 50% of submissions within 24 hours and 90% within 48 hours, according to Apple. Google Play requires new personal developer accounts to run a closed test with at least 12 testers for 14 days. VirtuoLab works in short sprints with interim demos, and the schedule is part of the quote.

Does VirtuoLab build native or cross-platform apps?

VirtuoLab builds both, and the choice depends on the budget and on what the app needs from the phone. First, both platforms matter: Android had about 68% of the mobile operating system market in the Netherlands in September 2026 and iOS about 32%, according to StatCounter. A cross-platform app is one codebase for iOS and Android, built with React Native or Flutter. As an indication, a cross-platform app for both platforms costs €15,000 to €60,000. Native apps are two separate apps, for example with Swift for iOS, and cost €40,000 to €120,000 for both platforms. Native development makes sense when an app depends heavily on device features or on maximum performance. For many business apps, React Native or Flutter is enough and saves budget. The backend uses Node.js, TypeScript and PostgreSQL. Publishing requires an Apple developer account at €99 per year and a Google Play account at €25 once. Hosting an app backend typically costs €50 to €500 per month.

Does VirtuoLab offer maintenance and support after launch?

Yes, VirtuoLab offers support after launch on working days, Monday to Friday from 09:00 to 18:00. Support is provided by VirtuoLab directly, and because VirtuoLab is a one-person business, round-the-clock support is not part of the offer. Launch and support is the fourth step of every project. First, the software goes live. Second, the users receive training. Third, ongoing support starts. Issues and questions can be reported through the Support Desk on virtuolab.dev, by email at info@virtuolab.dev or by phone. New features can be added after launch as further development. Running costs depend on the product. For example, hosting, monitoring and further development of a KPI dashboard built with Microsoft Power BI cost €150 to €750 per month as an indication in 2026. Hosting an app backend typically costs €50 to €500 per month. The client owns the source code and the data, so another developer can also maintain the software later.

Can VirtuoLab improve an existing website or app?

Yes, VirtuoLab can improve an existing website or app, provided the source code or an admin account is available. Typical improvements are speed, design, new features and security. First, security is a common reason: 91% of the 11,334 WordPress vulnerabilities reported in 2025 were in plugins, according to Patchstack. For example, an existing WordPress site can get a custom plugin, from €2,000 to €5,000 for a simple version. Second, an existing system can be linked to other software with an API integration, starting at €1,500. Third, an existing website can become easier to find in Google and in AI assistants such as ChatGPT through SEO and GEO. Not every old system is worth extending, though. Sometimes a rebuild with Next.js and PostgreSQL costs less in the long run than patching outdated code. The free intake call shows which route fits, followed by a fixed price for the chosen improvement.
