The Challenge
The core challenge was bridging the gap between static content and dynamic AI interactions. Implementing a RAG-based AI assistant that accurately retrieves real-time product specs from PayloadCMS was complex. Additionally, orchestrating the 'Quote-to-Invoice' workflow—where approved quotes automatically trigger PDF generation and email dispatch via Server Actions—required precise state management to prevent data inconsistencies.
TECHNOLOGIES USED

The Solution
→ Next.js 15 + PayloadCMS 3.0 + Neon DB for a robust enterprise architecture. → Google Gemini 1.5 Flash (RAG) for AI-driven live inventory intelligence. → Stripe + Payload Hooks + Resend for automated quoting and invoicing workflows.

Core Integrations
Key Decisions
Why PayloadCMS over WordPress?
Needed a developer-first, headless CMS that seamlessly integrates with a modern Next.js stack while providing strong typing via TypeScript.
Why RAG for the AI?
LLMs hallucinate. By using Retrieval-Augmented Generation, we forced the AI to only answer using the exact stock data from our database.
Why React PDF?
We needed pixel-perfect, automated invoice generation. React PDF allowed us to build invoices using the same component logic we use for the web.
What I Learned
Hardest Part
Orchestrating the post-purchase webhook lifecycle where Stripe confirms payment, triggers Payload hooks, generates a PDF, and emails the client via Resend.
Biggest Insight
Serverless databases (Neon) are incredible for scaling, but managing connection pooling in serverless functions is critical to prevent cold start timeouts.
Do Differently
I would introduce a queueing system like Upstash/Redis for the email processing to ensure the checkout UI resolves instantly regardless of third-party API delays.
