Overview
Lunabook is my own SaaS product in development: a calm all-in-one app for the self-employed in the DACH region, uniting CRM, bookkeeping and project management on one shared data foundation. The special part: an AI assistant you simply tell what you need in plain language — “create an invoice of €1,200 for Studio Krause” — and Lunabook does it. Concept, UI/UX, design and the entire development are mine.

The idea
The self-employed juggle three or four tools today: one for invoices, one for customers, one for projects — and nothing talks to each other. Lunabook puts everything on one shared data root: a quote becomes an invoice in one click, receipts flow into the reports automatically, the customer is attached to every record. “Order that never sleeps.”
The AI assistant
The heart of it is an AI assistant with real tool access: it creates customers, writes quotes and invoices, answers questions about your numbers — straight from the chat. On top, a receipt AI reads uploaded invoices automatically (vendor, date, amount, tax rate) and books them into the right category. You say it, Lunabook does it.
Serious bookkeeping
Behind the calm surface sits real depth: e-invoicing (ZUGFeRD), cancellation, down-payment and final invoices, gapless numbering, live tax logic for DE/AT/CH, VAT reports and a dedicated tax-advisor access with its own firm cockpit. Hosted in the EU, GDPR-compliant — built as a multi-tenant SaaS.
