  • Clean UI/UX design focused on user experience

FAQ

Common Questions

When does it make sense to build custom software?

Custom software makes sense when off-the-shelf products don't fit your workflows, when you need deep integration with existing systems, when you have unique compliance requirements, or when the long-term cost of licensing generic software exceeds the investment in a tailored solution. We'll help you make that assessment honestly during our initial consultation.

How long does it take to build a custom application?

Timeline depends on complexity. A focused web application or Frappe custom module typically takes 6–12 weeks. A full-featured platform with mobile app and complex integrations may take 3–6 months. We deliver in sprints so you have working software within the first few weeks, not at the end of the project.

Will the software integrate with our ERPNext system?

Yes — deep ERPNext integration is one of our core strengths. Since we build on the Frappe framework, our custom apps can share the same database, authentication, and APIs as your ERPNext instance. This means real-time data sync, single sign-on, and no duplication of master data across systems.

Do we own the source code?

Yes. All code we write for you is fully owned by you. We deliver complete source code, documentation, and deployment instructions. You are never locked into working with KCSC exclusively — although most clients choose to continue with us for ongoing support and enhancements because of the relationship and deep system knowledge we develop.

What happens after the software is launched?

We provide a warranty period after launch to fix any bugs at no additional cost. After that, we offer ongoing support and maintenance retainers covering bug fixes, security updates, performance optimization, and feature enhancements. We treat every application we build as a long-term partnership, not a one-time project.

Can you work with our existing development team?

Absolutely. We can work as a fully independent development team, or we can collaborate closely with your in-house developers. We follow clean coding standards, write comprehensive documentation, and use standard version control workflows (Git) that make it easy for any technical team to work alongside us or take over the codebase.
