Why I Built a Full-Stack Automotive ERP with Next.js 15 and shadcn/ui

Hey Dev.to! 👋

I wanted to share a deep dive into my latest project: MileMoto. It’s a production-ready, full-stack Automotive ERP and eCommerce storefront built entirely from scratch.

As a full-stack engineer who spends a lot of my free time modifying and working on cars, I've noticed a massive technical gap in the automotive industry. Most local tuning shops, garages, and independent auto parts stores are running their businesses on clunky legacy software from a decade ago.

When they try to move online, shoehorning automotive inventory (which requires highly specific vehicle fitments, multiple vendor supply chains, and complex profit margins) into a generic Shopify or WooCommerce store usually results in an absolute nightmare of expensive custom plugins.

I wanted to bridge the gap between clean code and car culture, so I spent the last few months architecting a native solution.

🛠️ The Tech Stack

Here is the architectural foundation I settled on to ensure the system is fast, secure, and highly scalable:

Framework: Next.js 15 (App Router) for unified frontend and backend API routing.
Language: TypeScript for strict type-safety across complex data structures.
UI/UX: Tailwind CSS and shadcn/ui for a dense, highly professional, and responsive admin dashboard.
Payments: Native Stripe integration with pre-configured webhooks to sync global transactions directly with an internal accounting ledger.

🏗️ Architectural Highlights

1. SEO & Instant Load Times via SSR

For automotive retail, organic search traffic is everything. If someone searches for a hyper-specific part number, your page needs to index perfectly on Google and load instantly. I leaned heavily into Server-Side Rendering (SSR) in Next.js 15 to ensure that thousands of complex part pages serve static-like speeds while pulling dynamic inventory details under the hood.

2. Dense Data Management with shadcn/ui

ERP dashboards require displaying massive amounts of real-time data—purchase orders, vendor lists, P&L metrics, and stock levels—without overwhelming the user. Using shadcn/ui allowed me to retain complete control over the underlying component code, optimizing tables and modal sheets for dense data entry while keeping the design clean and accessible.

💡 Changing the Distribution Model: Why Code Over SaaS?

When I first started building this, the natural instinct was to launch it as a standard B2B monthly SaaS.

However, I realized that the fastest way to actually modernize local auto shops isn’t by trying to sell a subscription to individual shop owners who are busy wrenching on cars. It’s by empowering the web developers, freelancers, and local agencies who are already hired to build websites for them.

So, I packaged the entire codebase into a clean, un-monetized script and pushed it to CodeCanyon. Agencies can buy it once, completely customize the branding or add unique client logic, and deploy an enterprise-grade stack for their automotive clients in days instead of months.

🚀 Launching Tomorrow & Looking for Feedback!

We are officially launching on Product Hunt tomorrow morning (June 6)!

Since the product is built entirely by a solo developer and fully bootstrapped, I would absolutely love to hear from this community.

How do you typically handle heavy, multi-nested state variables when managing real-time inventory lists?
If you've ever built software for local brick-and-mortar industries, what was your biggest technical hurdle?
