    Fiscal Receipt and Issuance of Invoices

    Tax automation

    Turns the clinic's administrative invoices into real fiscal receipts, no manual typing.

    What it does

    Built for businesses that can't rely on someone typing every invoice by hand into the fiscal system. Each type of service comes with its own rules (taxes, fields, format), and the automation recognizes each one and applies the right rule, without mixing them up.

    How it's used

    1. The clinic's administrative system generates the invoice as a PDF
    2. The data is extracted and classified by service type
    3. It's formatted into the exact JSON the fiscal provider requires
    4. It's sent to the fiscal printer to issue the real invoice
