Key concepts
Step by step
cd ~/proyectos-ia mkdir asistente-autonomo cd asistente-autonomo claude
Run on your computer
npm install npm run dev
Create a test invoice and export it to PDF.
If something goes wrong
- Incorrect totals — tell Claude Code the exact VAT/IRPF percentage for your situation; ask it to show the breakdown.
- Lost data — that's why we insist on backups; restore the latest one.
- The PDF looks bad — ask for a cleaner invoice design with your logo.
Practice challenge
Add reminders for unpaid invoices and a button to generate the quarterly summary ready to send to your accountant.
