FAQ
What does the Basic package include?
One responsive Next.js screen built from your supplied design. This is frontend UI only. Functional AI, backend development, login, databases and payments are not included. If you need design work too, message us for a separate quote.
What is the difference between Standard and Premium?
Standard covers one small AI feature with a simple interface, one AI provider integration and deployment. Premium covers a focused MVP with login, a database, one core AI workflow and up to three screens. We confirm the exact scope before starting.
Can you build a complete AI SaaS platform?
Yes. Larger platforms with multiple workflows, admin tools, subscriptions or complex integrations require a custom offer. Share your requirements so we can recommend suitable milestones, pricing and delivery dates.
Are hosting and AI API costs included?
No. Hosting, domains, AI usage and third-party subscriptions are paid separately through your accounts. We identify the required services during scoping and explain which costs depend on usage.
Can you improve an existing or AI-generated application?
Yes. We can review applications built with Claude Code, Codex, Lovable, Replit or other tools. We assess the existing code and requirements before quoting repairs, integrations or further development.
Can you build chatbots, RAG or AI agents?
Yes, through an agreed scope. Document retrieval, advanced chatbots and agent workflows may require additional data processing, integrations and testing. These are not automatically included in the listed packages.
Will I receive the source code?
Yes. You receive the agreed custom source code and relevant setup instructions. Third-party libraries, services and assets remain subject to their respective licences.
What counts as a revision?
A revision is a consolidated round of adjustments within the agreed requirements. New screens, features or integrations are additional scope. Bugs are issues where the delivered work does not meet the agreed requirements.
Should I contact you before ordering?
Please message us first if you are unsure which package fits, need an existing application reviewed, or require custom functionality. We can confirm the scope and recommend the appropriate package or custom offer.
