En tant que freelance, je jonglais entre des fichiers éparpillés pour suivre mes clients, et c'était le chaos. Ce cours m'a appris à construire mon propre CRM sur mesure pour centraliser mes contacts et suivre chaque échange. La partie sur la conception de la base de données client était claire et vraiment adaptée à un petit budget. J'ai maintenant une appli où tout est enfin organisé au même endroit. J'aurais aimé un peu plus sur l'envoi automatique de relances, mais dans l'ensemble c'est exactement l'outil qu'il me manquait.
