What's inside
  • A 10-section agency prompt stack, tested as you go

  • A personalized client dashboard and dynamic data tables
  • Stripe payments, invoices, and an admin panel with automation
  • A Supabase database you own, live on a custom domain

Solo Builder, Agency Pricing

Clients don't pay for lines of code — they pay for full-stack functionality. Prompt Greta to build a complete client portal: user accounts, dynamic data tables, custom dashboards, and Stripe payments, deployed to a live URL before agencies finish their discovery call.

The Staged Agency Build

Ten focused sections, tested as you go: foundation and stack, a trustworthy SaaS design system, auth with per-client data isolation via row-level security, the database schema, the portal shell, a custom client dashboard, dynamic data tables, Stripe payments and invoices, an admin panel with automation, then responsiveness, SEO, and deploy.

What You Deliver

A multi-thousand-dollar client portal — a full-stack platform with a Supabase database you own, secure client logins, Stripe payments, dynamic tables, and a custom-domain deploy. Iterate forever by chat, and charge agency prices as a team of one.

The full 10-section prompt stack is in the PDF.
