| Data extraction from forms | Smart Fax returns fields | PDF only |

| Entry price | $39/mo | ~$25/mo (300 pp, annual) |
Documo is a strong, compliant fax service, but it is still fundamentally about transmitting documents. Faxday adds the operational layer: every inbound fax gets an owner, a status, and an SLA; Smart Fax returns structured data instead of a PDF; and Sanga summarizes, files, and helps draft. For teams whose faxes trigger work, that layer is the point.
Documo has a reputation for clean fax output and reliable delivery, and it includes HIPAA across plans. If you want a polished, no-frills compliant fax service and do not need workflow, data extraction, or AI, it is a solid pick.
