OfferteFlow is a finished, ready-to-launch quote maker for freelancers and small businesses. Users fill in a customer, add their items and click PDF – the result is a professional quote with their own logo, correct tax and a signature box.

No backend, no database, no paid APIs and no build step – running costs are €0. Data is stored locally on the user's device, which is a strong privacy argument.
