FAQ

EXTFOX offers comprehensive software development services across three core areas: Shopify commerce development (custom stores, checkout extensions, subscriptions, headless commerce, performance optimization), AI & automation (AI chatbots, RAG systems, AI voice agents, AI integrations), and product development (MVP development, full-stack web applications, SaaS platforms). We specialize in building scalable, intelligent solutions for enterprise brands and Shopify Plus merchants.
We provide comprehensive Shopify Plus development including custom store development with advanced features, checkout extensions using Shopify Functions and UI Extensions, subscription and recurring revenue solutions, headless commerce implementations, and performance optimization. Our checkout extensions help increase conversion rates and average order value through native solutions that outperform private apps.
RAG (Retrieval-Augmented Generation) systems combine information retrieval with AI generation to provide intelligent, context-aware responses. They're ideal for knowledge management, intelligent search, content creation, and customer support. RAG systems understand your business context and deliver accurate, relevant information from your data sources, improving decision-making and customer experience.
We build SaaS platforms from MVP to enterprise scale with subscription management, multi-tenancy, advanced features, and scalable architecture. Our approach includes rapid MVP development for market validation, full-stack development with modern technologies, cloud infrastructure setup, and ongoing optimization. We focus on creating solutions that drive real business results and scale with your growth.
AI automation streamlines operations, reduces manual work, and improves efficiency across your organization. We build AI chatbots and assistants for customer support, workflow automation systems, intelligent decision-making tools, and custom AI integrations. AI automation can handle repetitive tasks, provide 24/7 customer support, analyze data for insights, and automate complex business processes.
Our MVP development process focuses on rapid validation and iteration. We start with understanding your product idea and market fit, then build a minimal viable product with core features to test with users. This approach helps validate your concept quickly, gather user feedback, and iterate before investing in full-scale development. MVPs typically launch in 4-8 weeks depending on complexity.
Shopify checkout extensions (Functions and UI Extensions) are native solutions that run within Shopify's infrastructure, providing better performance, security, and reliability than private apps. They have no API rate limits, can modify checkout UI directly, require minimal maintenance, inherit Shopify's security, and execute at the edge for optimal performance. Private apps are legacy solutions with limitations; extensions are the future of Shopify customization.
We use modern, scalable technologies for full-stack development including Next.js, React, TypeScript, Node.js, Python, and cloud platforms (AWS, Azure, GCP). Our applications are built for scalability, performance, and exceptional user experiences. We choose technologies based on your specific needs, ensuring optimal performance and maintainability.
We build intelligent conversational AI that understands context, provides accurate responses, and enhances customer experience. Our chatbots integrate with your existing systems, can handle complex queries, provide 24/7 support, and learn from interactions. They can be deployed on websites, messaging platforms, or integrated into your applications for seamless customer support.
Headless commerce separates the frontend from the backend, giving you maximum flexibility to build custom storefronts with any technology while Shopify handles commerce operations. Benefits include unique brand experiences, better performance, flexibility to use modern frontend frameworks, and the ability to create omnichannel experiences. It's ideal for brands needing custom experiences beyond standard Shopify themes.
Yes, we develop HIPAA-compliant AI voice agents for healthcare, real estate virtual assistants, customer service automation, and other industry-specific applications. Our voice agents understand context, handle sensitive data securely (including HIPAA compliance), integrate with your CRM, EHR, or business systems, and provide natural conversational experiences. We build custom voice solutions tailored to your industry requirements and compliance needs.
Timeline depends on project scope and complexity. MVPs typically take 4-8 weeks, full SaaS platforms can take 3-6 months, checkout extensions take 2-3 days, and AI systems vary based on requirements. We provide detailed timelines during discovery based on your specific needs. We focus on delivering value quickly while ensuring quality and scalability.
