About the creator

Automation engineer. I build tools for teams that bill clients and hate doing it manually.
I have been building automation systems for agencies, freelancers, and small teams since 2021. Invoice Automation Kit is the tool I built for my own clients first. Every layout, every field, and every shortcut came from real invoicing friction.

A skills folder you use with Claude Code or Codex. Save seller and client records, pick from 10 invoice layouts, add line items, let the agent calculate totals, apply taxes and discounts, support multiple currencies, and export to PDF. Everything is stored locally in SQLite.
No cloud account, subscription, or third-party API key is required. Clone the repository, point your coding agent at the folder, and follow the included setup instructions.
