Case Study

Before

Freelancers and solopreneurs needed a quick way to generate professional invoices without signing up for accounting software. Existing solutions were either too complex or required subscriptions.

After

Delivered a free, privacy-first invoice tool that generates professional PDFs in seconds. No sign-up required, all calculations done locally. Used by freelancers across the portfolio network.

How it's solved

Built a browser-based invoice generator with live preview, custom branding (logo, colors), tax calculations, and PDF export. All processing happens client-side — no data leaves the browser, ensuring privacy.

Trade-offs

No payment collection built in — it generates the document, not the transaction.
