Our verdict on InterFAX
InterFAX is Upland Software’s cloud fax service for organizations that need inbound and outbound faxing without maintaining fax hardware or phone lines. Teams can send and receive through a web interface, email, mobile web access or a developer API. Its automation, delivery records and routing make it relevant to organizations connecting fax workflows to existing systems, including healthcare and financial services teams. It is positioned for small, mid-market and enterprise organizations.
Workflow integration is a central part of the offering. The API supports REST and SOAP, while automated routing, reception and delivery can connect fax handling to business processes. Integrations include Salesforce, Epic, OncoEMR, Microsoft Outlook and SAP R/3. OCR-based extraction and indexing add a way to organize fax documents, and delivery confirmations and transmission records support traceability. These capabilities suit teams with recurring or system-driven fax work better than organizations looking only for occasional, manual sending.
Pricing is tailored through sales rather than presented as a standard plan, so buyers should discuss expected usage and requirements directly with Upland. InterFAX offers a 30-day trial, and support channels include phone, chat and documentation. Its listed compliance posture includes HIPAA, PCI DSS and ISO 27001. Mobile access is through responsive web rather than native iOS or Android apps, despite platform listings that include those operating systems. Choose InterFAX when API access, routing, delivery records or integrations matter to the workflow; look elsewhere if a published plan price or native mobile app is essential.
