Why a custom app? Benefits for your business

01

Tailored fit

An application that perfectly matches your processes, without unnecessary features.
Off-the-shelf SaaS solutions often fall short in addressing a company’s unique requirements and nuances of highly specific, internal business processes. On the other hand, a custom application is built from the ground up to align precisely with your unique workflows and operational needs. This means you get a solution that includes all the essential features for your business – and only these, eliminating superfluous functionalities that clutter interfaces and complicate user adoption.

02

Scalability

A solution that grows with your business.
tvn-lightgray
Custom applications are designed with future growth in mind, providing the flexibility to handle increased data volumes, more users, and new functionalities without compromising performance. This inherent scalability ensures that your investment continues to deliver value, adapting seamlessly to new market demands and strategic initiatives.

03

Performance

Optimal architecture and technology for your needs.
Slow loading times, frequent crashes, and sluggish responsiveness in existing applications can severely impact productivity and user satisfaction. This poor performance often stems from outdated technology, inefficient code, or inadequate infrastructure. Such issues not only frustrate users but also result in lost work hours and reduced operational efficiency. With a custom app, you have control over many of these aspects and can design your system to minimize performance issues.

04

Integration

Seamless connection with existing systems (CRM, ERP, etc.).
tmobile-gray
A custom application can be designed to integrate seamlessly with your existing CRM, ERP, accounting, or other critical platforms. This interconnectedness eliminates data silos, ensures data consistency across departments, and automates information flow, providing a unified and accurate view of your operations. Such integration enhances decision-making and reduces the administrative burden of managing disparate systems.

05

Security

The highest standards of data protection and privacy.
Data security and privacy are a concern for any business. With a custom application, you have complete control over the implementation of security measures. You can tailor access controls, enable top-of-the-line encryption protocols, and adhere to specific regulatory compliance requirements to safeguard your sensitive information against threats and maintain stakeholder trust.

06

Ownership

Full control over your code and data.
Opting for a custom application grants you ownership of the software's code and the data it processes. You are not reliant on a third-party vendor for updates, modifications, or access to your own information. This level of control provides unparalleled flexibility for future development, ensures business continuity, and protects your intellectual property, giving you complete autonomy over a critical business asset.

07

Competitiveness

Unique functionalities giving you a market edge.
play-lightgray
Ready-made SaaS solutions often fall short in addressing the unique and nuanced requirements of a business. Their generic features and rigid structures can lead to compromises, forcing companies to adapt their processes to the software rather than the other way around. A custom application can provide a distinct market advantage, whether it's a proprietary algorithm, an innovative customer interaction tool, or a highly specialized operational feature. Such bespoke capabilities can help you stand out from the competition, attract new clients, and drive sustained business growth.

08

Long-term costs

Eliminating unnecessary licenses and apps with expensive business models.
The cumulative licensing fees for multiple software solutions, especially those with per-user or feature-based pricing, can quickly escalate into a significant operational expense. These costs often include features that are never fully utilized, resulting in a low ROI. As businesses grow, such escalating licensing costs can become a significant financial burden, to the point where investing in a custom solution becomes a more viable alternative.

Team augmentation

When you need to quickly fill specific skill gaps within your existing team, we can provide experienced specialists with expertise in particular frameworks and technologies to seamlessly integrate with and strengthen your in-house capabilities.

FAQ

Custom app development involves creating software applications specifically tailored to your business's unique needs, processes, and goals. Unlike off-the-shelf solutions, custom apps are built from the ground up to fit your exact requirements, ensuring maximum efficiency and relevance.

Off-the-shelf software is designed for a broad audience and offers general functionalities. Custom development, however, creates a unique solution built precisely for your specific workflows, integrations, and branding. This means no unnecessary features and no compromises on functionality crucial to your operations.

You should choose a custom app if off-the-shelf solutions don't fully meet your needs, lack specific features, are not scalable enough, or don't integrate well with your existing systems.

Our process typically begins with in-depth consultations and analysis, which enable us to understand your vision and requirements. We then enter the design phase, during which our software architects and developers plan a solution that answers your needs and provides the best business value. Afterwards, the solution is developed, tested and deployed. We can also provide ongoing maintenance and improvements.

The timeline varies significantly depending on the app's complexity, features, specific requirements, and the technology used (for example, low-code platforms can significantly accelerate development). A simple app might take a few weeks, while complex enterprise solutions could take several months. We'll provide a detailed timeline after our initial discovery phase.

Absolutely! We provide comprehensive post-launch support and maintenance services. This includes bug fixes, performance monitoring, security updates, and ongoing feature enhancements to ensure your app remains secure, efficient, and up-to-date.

Yes, seamless integration is one of our core strengths. We can integrate your new custom app with various third-party systems.

The cost of a custom app depends heavily on its complexity, the number of features, the technologies used, and the development timeline. We offer transparent pricing based on project scope. After an initial consultation and requirement analysis, we can provide you with an estimate.

For many businesses, yes. While the initial investment may be higher than off-the-shelf options, a custom app can significantly improve efficiency, reduce long-term operational costs, provide a unique competitive advantage, and scale perfectly with your growth, leading to substantial long-term ROI.

We leverage a wide range of modern and robust technologies, including popular frameworks and languages such as React, Angular, Vue.js, Node.js, Python, Ruby on Rails, PHP, and various cloud platforms like AWS, Azure, and Google Cloud, as well as SQL and NoSQL databases. We’re also uniquely proficient with low-code platforms such as Oracle APEX and Mendix (we are official partners for both of these companies). Our choice of technology depends on the specific needs and scalability requirements of your project.

Security is paramount. We implement industry best practices throughout the development lifecycle, including secure coding standards, regular security audits, data encryption, robust authentication mechanisms, and compliance with relevant data protection regulations (e.g., GDPR). Your data and intellectual property are always protected.
