About this business

CertTrack is a ready-to-launch B2B SaaS designed to solve a highly specific and expensive problem: managing subcontractor compliance documents in the Portuguese construction industry. The Problem: Construction companies are legally required to keep subcontractor licenses (alvarás), insurance, and medical fitness certificates up to date. Failing to do so results in heavy fines and civil liability. Currently, most companies manage this with Excel spreadsheets or physical folders. The Solution: CertTrack centralizes these documents, automatically calculates expiration states (valid, expiring, expired), and sends automated email alerts before a document expires. The Tech Stack (Built for scale): Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS 4. Backend & Auth: Supabase (Postgres) with Row Level Security (RLS) for complete data isolation between tenants. Automation: Vercel Cron Jobs for daily email alerts. Payments: Stripe integration ready (Subscription model: €29/month for Pro plan). Emails: Resend integration for notifications and team invites. Quality: Production build and type-checking pass with zero errors. No ignoreBuildErrors hacks.

Highlights

Modern, scalable codebase: Built with Next.js 16, React 19, and TypeScript with zero build errors. Secure by design: Supabase Row Level Security (RLS) isolates data between different companies/tenants. Ready for automation: Vercel Cron jobs configured for daily email alerts.

Growth opportunities

Targeted B2B outreach: The Portuguese construction sector is highly fragmented and lacks digital solutions. Direct sales to small contractors are highly viable. Feature expansion: Add a portal for subcontractors to upload their own documents (saving time for the main contractor). New markets: The

Risks to consider

Pre-revenue: The product has no paying customers yet and no active Stripe account (the buyer must create their own Stripe account). Legal review needed: The Terms of Service and Privacy Policy are drafts and need to be reviewed by a lawyer (especially regarding GDPR and medical data from fitness ce
