Design exploration / Neo-brutalism
Stackd
Freelancer invoicing with thick outlines, bright colour, and a live invoice-building demo.

The idea behind the interface.
A marketing website for a fictional invoicing tool, built around hard shadows, expressive typography, and bold flat colour. Beneath the visual personality is a practical product journey: explore features, build a sample invoice, compare plans, and read release notes.
Inside the build
- The interactive invoice preview responds to client, amount, currency, description, and due-date inputs without storing them.
- Billing and currency controls share one pricing model, with shareable state and region-aware defaults.
- A static Next.js export includes Markdown release notes, an RSS feed, responsive component states, and a pausable integration marquee.
Scope & context
