mFax, now Documo, is a paid cloud fax platform launched in 2017 for healthcare organisations. Users can send and receive faxes from a browser without fax machines or phone lines, with web, iOS, and API access. Its REST Cloud Fax API supports programmatic sending and receiving, delivery tracking, and document-processing triggers. OCR and AI features classify documents, extract patient data, and create searchable PDFs from faxes and scans. Listed EHR integrations include Open EMR, ModMed, NextGen Enterprise, and PointClickCare. Documo states that the service is HIPAA compliant, SOC 2 Type II audited, and HITRUST e1 certified, with a BAA available. Transmissions use TLS 1.2 or later and AES-256, with actions recorded in an audit trail. Plans start at $25.00 USD per month billed annually. A 14-day trial includes 100 pages; the Solo plan includes 300 pages monthly, one user, and one fax number.
