FAQ
What do you need to start my MERN stack web application?
Please send your business goal, target users, required features, user roles, reference applications, integrations, design status, hosting preference, and target deadline. We will review the requirements and confirm the scope before development begins.
Can you develop a SaaS MVP from an initial idea?
Yes. We can help convert your idea into a structured SaaS MVP by defining the core user journey, must-have features, technical architecture, development milestones, and launch requirements.
What is included in your MERN stack development service?
Depending on the package, development may include React or Next.js frontend development, Node.js and Express/NestJS backend development, MongoDB database design, APIs, authentication, responsive UI, testing, deployment, documentation, and source code.
Can you build ERP, CRM or admin dashboard systems?
Yes. We build custom ERP/CRM modules, internal business tools, admin dashboards, reporting systems, approval workflows, inventory systems, and automation platforms. Large systems require a custom feature-based quote.
Can you integrate Stripe, PayPal, CRMs, AI tools or third-party APIs?
Yes. We can integrate payment gateways, subscriptions, email services, analytics, CRM systems, cloud storage, AI APIs and other third-party platforms. Integration costs depend on complexity and documentation quality.
Will my SaaS or web application be scalable and secure?
We design applications using maintainable architecture, role-based access, validation, secure authentication, structured database design, performance-aware APIs, and deployment best practices. Specific load or compliance requirements should be discussed before ordering.
Do you also provide UI/UX design?
Yes. We can work from your existing Figma design or provide UI/UX design as part of a package or gig extra. Design scope and revision limits will be confirmed before starting.
Do you provide cloud deployment and DevOps support?
Yes. We can deploy applications to AWS, Vercel, VPS or another suitable environment. Hosting accounts, paid services and third-party infrastructure charges are normally paid by the client.
What is considered a revision?
A revision is an adjustment within the approved feature scope. New modules, user roles, workflows, integrations or major design changes are treated as additional work and require a gig extra or custom offer.
Will I receive source-code ownership and post-launch support?
Yes. You will receive the agreed source code and handover documentation after completion. Each package includes a defined bug-support period, and ongoing maintenance can be arranged separately.
