Why Need This?

Suitable for businesses like yours

Custom web applications are suitable for companies or startups that need software with specific requirements that cannot be found in the finished product. For example, factory operational monitoring dashboards, special CRM applications for sales teams, warehouse inventory systems with unique workflows, SaaS platforms for new business ideas, paid member portals, attendance systems with facial recognition, or internal tools for automating manual processes. We build from the ground up with a modern stack of Next.js, TypeScript, and scalable databases like PostgreSQL or MongoDB — ready for thousands of users.

FAQs

Frequently asked questions

What's the difference between a custom web app and a regular website?
Regular websites focus on content and promotion (one-way information). Custom web apps have complex business logic, user interactions, databases, authentication, and workflows — similar to software applications but accessed via a browser.
How long does the work process take?
Depends on complexity. Simple applications 3-4 weeks, medium applications 6-8 weeks, enterprise applications can take 3-6 months. We will make a clear roadmap at the beginning after the discovery session.
Is the source code mine?
Yes, 100%. After payment, you get full source code, documentation, and access to the GitHub/GitLab repository. There are no royalties or continued licensing fees.
What is the payment system for custom projects?
Usually divided into 3 terms: 40% down payment at contract, 30% when prototype/UI is approved, 30% payment when deploying production. A written contract will be provided prior to start.
Do I get maintenance after going live?
Yes. We provide a free bug-fix guarantee 30 days after go-live. After that, consultations remain free, and monthly maintenance packages are available for feature updates, security and server monitoring.
