In Brazil's healthcare ecosystem, thousands of independent professionals must issue tax receipts for the services they provide.

In Brazil's healthcare ecosystem, thousands of independent professionals must issue tax receipts for the services they provide. This process —known as the issuance of Notas Fiscais Eletrônicas (NFS-e)— varies from one municipality to another and often requires technical and fiscal knowledge that is not always accessible to healthcare professionals. To address this challenge, the goal was to create a unified digital platform that would simplify the fiscal and administrative management of doctors, psychologists, physiotherapists, nutritionists, and other specialists.
