Fax Platforms That Go Beyond Basic Faxing

Automation, Programmability, and Modern Workflows

Fax is still a critical communication channel in healthcare, government, finance, and legal environments—but basic send-and-receive fax is no longer enough.

Modern organizations need fax to:

• Trigger workflows

• Integrate with systems and applications

• Support automation, not manual handling

• Fit into broader communication and document processes

While many vendors still focus solely on fax transmission, a small group of platforms treat fax as an input to automated workflows rather than an endpoint.

Below are fax platforms that go beyond basic faxing, each adding a distinct “something else” on top of native fax capabilities.

1. FaxSIPit — Fax + Fully Customizable Workflow Automation via API

FaxSIPit is designed for organizations that need reliable and secure fax as programmable infrastructure, not a standalone application.

Instead of pre-defined templates or vertical-specific workflows, FaxSIPit exposes fax functionality through APIs, allowing teams to build custom workflows that match real-world processes. Fax becomes a trigger, an output, or a step inside broader systems and applications.

What goes beyond basic fax

• API-driven inbound and outbound fax workflows

• Custom routing, transformations, and logic

• Integration with existing systems and UC platforms

• Designed for IT-owned, regulated environments

Best suited for

• Healthcare, government, finance, legal

• MSPs and enterprises

• Teams that need flexibility, control, and customization

FaxSIPit’s “something else” isn’t a vertical workflow or messaging layer—it’s the ability to design your own fax workflows and a team of fax experts to support you.

2. ClickSend — Fax + Multi-Channel Automation

ClickSend treats fax as one channel within a broader communications automation platform that also includes SMS, email, and voice.

Fax is natively supported, but the primary value comes from orchestrating communications across multiple channels using automation rules and APIs.

What goes beyond basic fax

• Fax integrated with SMS, email, and voice

• Automation-first communication workflows

• API-accessible messaging across channels

Best suited for

• Operational teams

• Customer and service communications

• Organizations prioritizing multi-channel outreach

ClickSend’s strength is communication orchestration, whereas FaxSIPit focuses on fax-native workflow customization.

3. Twilio — Fax + Programmable Communications APIs

Twilio includes native fax as part of its programmable communications platform. Fax exists as a building block alongside voice, SMS, and other channels, accessible entirely through APIs.

Automation and programmability are core to Twilio’s value proposition, though fax itself is not the platform’s primary focus.

What goes beyond basic fax

• Fax embedded in a developer-first API ecosystem

• Event-driven automation

• Deep programmability across communication channels

Best suited for

• Developers and product teams

• Custom application workflows

• Communication-heavy software platforms

Twilio demonstrates how fax fits into programmable systems—but FaxSIPit focuses specifically on fax-native reliability, workflows, and compliance.

4. Esker — Fax Embedded in Document and Finance Process Automation

Esker uses fax as part of document-driven business process automation, particularly in accounts payable, accounts receivable, order processing, and finance operations.

Fax is natively supported but exists to serve automated workflows rather than as a standalone communications product.

What goes beyond basic fax

• Fax integrated into finance and document workflows

• Rules-based routing and processing

• Automation tied to ERP and back-office systems

Best suited for

• Finance and operations teams

• Document-heavy business processes

• Organizations modernizing AP/AR workflows

Esker’s “something else” is process automation. FaxSIPit’s is workflow customization across any system.

5. Tungsten Automation — Fax-Triggered Enterprise Workflows

Tungsten Automation enables organizations to automate processes initiated by inbound communications, including fax. Fax events can trigger downstream workflows, routing documents into business processes or automation pipelines.

What goes beyond basic fax

• Fax as a workflow trigger

• Integration with enterprise automation stacks

• Multi-channel document ingestion

Best suited for

• Large enterprises

• Capture and RPA-driven environments

• Process automation initiatives

Kofax positions fax as an input into enterprise automation, not as a standalone service.

6. HP Capture and Route — Fax as Part of Document Capture and Routing Automation

HP Capture and Route focuses on document capture, routing, and automation, often in environments with heavy scanning, MFP usage, and structured document workflows. Fax is included as one of several ingestion channels.

What goes beyond basic fax

• Automated document capture and routing

• Workflow-driven document delivery

• Fax integrated into capture pipelines

Best suited for

• Document-centric organizations

• Print-heavy or MFP environments

• Structured routing and archiving workflows

Fax is a component of the workflow—not the destination.

Why So Few Platforms Go Beyond Fax

Most fax providers focus on:

• Transmission reliability

• Hosting and compliance

• Replacing fax machines

Few invest in automation, programmability, or workflow customization, because doing so requires:

• Exposing APIs

• Supporting non-standard use cases

• Integrating deeply into customer systems

That’s why the list is short—and why the distinction matters.

Choosing the Right “Fax Plus” Platform

The right solution depends on what you need fax to do:

• Multi-channel messaging automation → ClickSend

• Programmable communications building blocks → Twilio

• Finance or document process automation → Esker

• Enterprise capture and process automation → Kofax or HP

• Custom, system-driven fax workflows → FaxSIPit

If fax needs to adapt to your workflows—not the other way around—API-driven customization becomes essential.

Fax Is No Longer Just a Transmission Layer

Fax hasn’t disappeared. It’s evolved.

In modern environments, fax:

• Triggers workflows

• Feeds automated systems

• Integrates into applications and processes

Platforms that recognize this treat fax not as a legacy tool, but as part of a programmable, automated workflow architecture.

That’s where the real differentiation now lives.
