Invoice Generator

You describe the work. This skill handles the rest. Give it client details, line items, rates, and payment terms — it builds a clean, professional invoice in markdown you can export straight to PDF.

Supports multiple currencies, tax calculations (flat rate or per-line), discount fields, and configurable payment terms. Tracks invoice numbers sequentially and maintains a simple client history so you're not reinventing the wheel every billing cycle.

Designed for freelancers and small agencies who bill regularly and don't want to open a separate tool every time. No subscriptions, no logins, no cloud. Just a clean invoice when you need one.
