Frequently Asked Questions
Everything you need to know about our Software Development Services.
ZENSOL Tech offers three core software development services: web development, including React, Next.js, Node.js, and ecommerce; mobile app development, including Flutter, React Native, iOS, and Android; and custom software development, including SaaS platforms, enterprise applications, and API development. We serve businesses in New York and across the United States.
ZENSOL Tech is a leading custom software development company serving businesses in New York and across the United States, with seven years of experience and more than 426 projects delivered. We stand out for our AI integrated development approach. Every product we build can incorporate machine learning, automation, and intelligent features from day one.
Costs depend on project complexity, feature scope, technology stack, and timeline. Zensol Tech offers transparent pricing with clear milestones. A basic MVP typically starts in the range of $15K–$40K, while complex enterprise platforms can range from $50K–$200K+. We recommend a free technical consultation for an accurate estimate based on your requirements.
Native development (Swift for iOS, Kotlin for Android) delivers maximum performance but requires separate codebases. Cross-platform frameworks (Flutter, React Native) share one codebase across both platforms, reducing development time and cost by 30–40%. Zensol Tech recommends cross-platform for most business apps and native for performance-critical applications like games or AR experiences.
A basic web application or MVP takes 4–8 weeks. Mid-complexity platforms with integrations take 2–4 months. Complex enterprise systems with multiple user roles and third-party connections take 4–8 months. Zensol Tech uses agile development with biweekly deliverables so you see progress throughout the project.
