Custom software development costs vary widely based on project scope, complexity, and timeline. Simple MVPs typically range from $25,000-$75,000, while full-featured applications can range from $100,000-$500,000+. Enterprise solutions with complex integrations and compliance requirements may exceed this. We provide detailed, transparent estimates after understanding your requirements during our free discovery call. Our VooStack methodology often reduces costs by 30-50% compared to traditional development approaches.

AgileStack offers both fixed-price and time-and-materials (hourly) billing models. Fixed-price works well for projects with clearly defined scope and requirements, providing budget certainty. Time-and-materials is better suited for projects where requirements may evolve or for ongoing development work. We also offer retainer arrangements for clients needing consistent development capacity. We recommend the most appropriate model based on your project characteristics.

Several factors influence software development costs: feature complexity and scope, design requirements (custom UI vs. standard components), third-party integrations, security and compliance needs (HIPAA, PCI-DSS, SOC 2), platform requirements (web, mobile, desktop), expected user scale and performance requirements, and timeline constraints. Projects requiring specialized expertise like AI/ML or embedded systems may also carry premium rates. We provide itemized estimates so you understand exactly what drives costs.

Yes, most software requires ongoing maintenance to remain secure, performant, and compatible with evolving platforms. Typical maintenance costs range from 15-25% of the initial development cost annually. This covers security updates, bug fixes, dependency updates, performance monitoring, and minor enhancements. We offer tiered maintenance packages tailored to your needs, from basic monitoring to comprehensive support with guaranteed response times.

Yes, we offer flexible payment structures for larger projects. Common arrangements include milestone-based payments (paying as specific deliverables are completed), monthly invoicing for time-and-materials projects, and phased project structures that allow you to launch an MVP before committing to full development. For qualified clients, we can discuss alternative financing arrangements. Our goal is to make quality software development accessible while managing cash flow responsibly.

Our development process follows an agile methodology with five key phases: Discovery (understanding requirements and defining scope), Design (architecture planning and UI/UX design), Development (iterative building with regular demos), Testing (comprehensive QA, security testing, and user acceptance), and Deployment (launch, monitoring, and handoff). Throughout the process, you have visibility into progress through regular updates, access to project management tools, and scheduled review sessions.

Project timelines vary based on scope and complexity. A simple MVP can be delivered in 6-12 weeks, while full-featured applications typically take 3-6 months. Complex enterprise solutions may require 6-12+ months. Our VooStack methodology accelerates timelines by leveraging pre-built components and AI-assisted development. During discovery, we provide a detailed project roadmap with milestone dates so you can plan accordingly.

Quality is built into every phase of our process. We implement automated testing (unit, integration, and end-to-end tests), conduct regular code reviews, and follow established coding standards. Before launch, projects undergo comprehensive QA testing, security audits, performance testing, and user acceptance testing. We maintain test coverage targets and use continuous integration to catch issues early. All code is documented and follows industry best practices.

After delivery, we provide a transition period that includes documentation, knowledge transfer sessions, and training for your team. We offer ongoing maintenance and support packages to keep your software running smoothly. This includes bug fixes, security updates, performance monitoring, and minor enhancements. We also remain available for future development phases as your needs evolve. Our goal is to be a long-term technology partner, not just a one-time vendor.

Client involvement is crucial to project success. At minimum, we request participation in weekly status meetings, sprint demos (typically every 2 weeks), and timely feedback on deliverables. You will have access to our project management tools to track progress in real-time. Some clients prefer daily check-ins during critical phases, while others delegate to a project manager. We adapt our communication cadence to your preferences while ensuring alignment throughout.

Change is expected in software development, and our agile process accommodates it gracefully. When new requirements emerge, we assess impact on timeline and budget, document the change, and get your approval before proceeding. For fixed-price projects, we use a formal change order process. For time-and-materials engagements, changes are incorporated into sprint planning. We prioritize transparency—you will always understand how changes affect the project.

AgileStack works with a wide range of programming languages, selecting the best fit for each project. Our primary languages include TypeScript and JavaScript for web development, Python for AI/ML and backend services, Swift and Kotlin for native mobile apps, Go and Rust for high-performance systems, and C/C++ for embedded software. We prioritize languages with strong ecosystems, long-term viability, and access to skilled talent.

Yes, we stay current with modern frameworks and continuously evaluate emerging technologies. For web applications, we frequently use React, Next.js, and Vue.js. For mobile development, Flutter and React Native are our go-to cross-platform solutions. On the backend, we leverage NestJS, FastAPI, and Express. We balance adopting modern tools with choosing battle-tested technologies that ensure long-term maintainability and talent availability.

Security is integrated throughout our development process. We follow OWASP guidelines, implement secure coding practices, and conduct regular security audits. Our process includes dependency vulnerability scanning, secrets management, input validation, encryption at rest and in transit, and authentication/authorization best practices. For regulated industries, we ensure compliance with standards like HIPAA, PCI-DSS, and SOC 2. We can also arrange third-party penetration testing.

VooStack is our proprietary development acceleration platform combining three elements: a library of pre-built, production-ready components (authentication, payments, admin dashboards, etc.), AI-powered code generation and review tools, and standardized architecture patterns optimized for rapid iteration. Instead of building common features from scratch, we assemble proven components and focus engineering effort on your unique business logic. This approach typically reduces development time by 50-90% for standard functionality.

Absolutely. System integration is a core competency. We regularly integrate with CRMs (Salesforce, HubSpot), ERPs (SAP, NetSuite), payment processors (Stripe, PayPal), communication platforms (Twilio, SendGrid), cloud services (AWS, Google Cloud, Azure), and countless industry-specific APIs. We build robust integrations with proper error handling, retry logic, and monitoring. For legacy systems without APIs, we can develop custom middleware or data synchronization solutions.

Post-launch support options include: bug fixes and issue resolution, security patches and dependency updates, performance monitoring and optimization, feature enhancements and iterations, user support escalation handling, and infrastructure management. We offer tiered support packages ranging from basic maintenance to comprehensive managed services. All plans include regular health checks and proactive recommendations for improvement.

Yes, we offer 24/7 support for mission-critical production systems through our Premium and Enterprise support tiers. This includes round-the-clock monitoring, on-call engineering support, and guaranteed response times for critical issues (typically 15-30 minutes). For business-hours support needs, our Standard tier provides coverage during US business hours with next-business-day response for non-critical issues.

Response times depend on your support tier and issue severity. Critical issues (system down) receive response within 15-30 minutes for Premium/Enterprise tiers and within 2-4 hours for Standard tier. High-priority issues are addressed within 4-8 hours, while normal requests receive response within 1 business day. We track all tickets in our support system and provide regular updates until resolution.
