AI SaaS Development
We build AI products that are ready for customers
Tech Agency Australia builds full-stack AI SaaS with authentication, billing, usage metering and monitoring in place from the first deploy.
What does AI SaaS Development include?
Product Strategy & Architecture
Validate your idea, define the feature set, and architect a scalable technical foundation before writing a single line of code.
Full-Stack Development
Next.js 15 + TypeScript frontend, API backend, database design, and third-party integrations — built to production standards.
AI Feature Integration
Embed Claude, GPT-4o, or specialised models as core product features — generation, analysis, classification, summarisation, and more.
Auth & Multi-Tenancy
Secure authentication with Clerk or NextAuth, role-based access control, and multi-tenant data isolation for SaaS requirements.
Billing & Subscriptions
Stripe integration with tiered pricing, usage-based billing, trial management, and Australian GST-compliant invoicing.
Launch & Scale
Production deployment on Vercel with CDN, monitoring, error tracking, and a scalable architecture ready for rapid user growth.
Questions about AI SaaS Development
What tech stack do you use to build AI SaaS products?
We build on Next.js 15 with TypeScript, Tailwind CSS, and Framer Motion for the frontend. Backend uses Next.js API routes or Node.js, with MongoDB or PostgreSQL for data. AI capabilities are powered by Anthropic Claude, OpenAI, or domain-specific models. Hosted on Vercel for global performance.
How long does it take to build an AI SaaS product?
An MVP with core AI features typically takes 6–10 weeks. A full-featured SaaS with authentication, billing, dashboards, and advanced AI capabilities takes 12–20 weeks. We use an agile approach with weekly demos so you see progress throughout.
Do you handle payment integration and subscriptions?
Yes. We integrate Stripe for payment processing, subscription management, usage-based billing, and invoicing — fully compliant with Australian GST requirements. We also handle trial management, upgrades, downgrades, and cancellation flows.
Who owns the code for the AI SaaS you build?
You own 100% of the code, IP, and all assets we produce. We deliver a full codebase handoff with documentation. We can also provide ongoing support and development retainers if you want us to continue building features post-launch.
Ready to scope something?
A strategy call runs 30 minutes on Australia/Melbourne time. You describe the process you want to automate, and we tell you whether it is worth building, roughly what it costs and what could go wrong. No deck.
