FAQ

Frequently Asked Questions

What is a custom web application?

A custom web application is software built specifically for your business's unique needs — accessed through a web browser — as opposed to off-the-shelf software. Examples include custom booking platforms, client portals, inventory management systems, SaaS products, and internal workflow tools. Custom web apps are built to fit your exact processes rather than requiring your business to adapt to a generic tool.

How long does it take to build a custom web app?

A simple MVP (Minimum Viable Product) with core functionality can be built in 8–12 weeks. A more complex application with multiple user roles, integrations, and advanced features typically takes 16–24+ weeks. ZAPSHERE provides detailed project timelines during the discovery and scoping phase.

How much does custom web app development cost?

Custom web application development costs depend heavily on the complexity of the application, number of user roles, integrations required, and development timeline. A simple MVP typically starts from $15,000, while complex SaaS applications or multi-user platforms can range from $40,000 to $200,000+.
