A compliant e-invoicing app, built in 1 hour
We pick an app together, and build it in 1 hour with the room. One hour at The Social Hub in Toulouse, in a small group. A freelancer's need laid out plainly, a mockup validated with the room, then the code: backend, front end, database, and going live from the room. We finished on the savings, and the subscriptions you get to cancel.
The goal
Build a real, compliant electronic invoicing tool in one hour, in front of the room: the idea turned into user stories, the design decided live, the code written with Claude Code, and the app online before the end.
The intent
Show that custom software is within reach of small businesses again. What used to take a team weeks now takes an hour, and electronic invoicing, mandatory from September 2026, was the perfect thing to prove it on.
