Fax.Plus vs. Concord Fax: Side-by-Side

Quick Answer

Fax.Plus is built for mid-market and enterprise teams that need a fax platform certified across a broader compliance stack, with real-time streaming built into the Enterprise API and data residency available in 20+ locations including the United States. Fax.Plus delivers a more modern platform, stronger independent certification, and greater flexibility than Concord without requiring a sales engagement to evaluate.

Why Teams Switch from Concord Fax

Most organizations evaluating Fax.Plus are not looking to switch because something broke. They are looking because they hit a specific limitation: a feature they need is not in their plan, or their compliance requirements extend beyond what a US-based infrastructure can cover by default. Here is where those gaps show up.

‍

1. The Feature You Actually Need Is Sold Separately

Time and again, the same story comes up when speaking with teams across industries: they are losing time not because of staffing or capacity, but because a competing facility saw the fax first. The Fax.Plus API delivers each page individually as it arrives via webhook, so your team starts reviewing page 1 while the rest is still transmitting. That response time advantage is available on Enterprise plans from day one. No add-on required.

‍

2. Pricing Transparency Stops at the Enterprise Threshold

Fax.Plus publishes all pricing. Basic starts at $6.99/month. Enterprise is $99.99/month for 4,000 pages, or $79.99/month billed annually. You can run the numbers, build your business case, and make a decision before talking to anyone.

Concord publishes entry-level FaxPro pricing from $10.95/month. At enterprise scale, pricing requires a demo and a commercial proposal. For procurement teams that need to justify a switch internally, that process adds weeks before you can even compare numbers.

‍

3. No Free Tier, and Enterprise Evaluation Requires a Sales Conversation

Fax.Plus does not require a demo or sales call to begin evaluation. Compliance documentation is public, delivery reliability is independently verifiable, and the platform is accessible from day one.

Evaluating Concord's enterprise product requires a sales engagement before you can test anything. For IT directors who need to run a proof-of-concept before committing a budget, that adds friction before the evaluation even begins.

‍

4. Integrations Outside the Microsoft and EHR Stack

Fax.Plus connects natively with Google Workspace, Microsoft 365, Slack, and Zapier, opening connections to thousands of additional tools without custom development. For teams running Google-first workflows or coordinating document routing through Slack, these integrations work out of the box.

Concord's Google Workspace support is limited to email-based fax send and receive. Slack and Zapier integrations are not available on the Concord platform.

‍

5. Data Residency on Your Terms

Fax.Plus stores US customer data in the United States as a standard configuration. No special arrangement, no additional cost. Organizations like Neuralink, Cloudflare, and PwC run on Fax.Plus with their data staying in the US by default.

For organizations with international operations, data residency is available in 20+ locations globally. Primary and backup data can be stored in separate locations, giving an additional layer of control that most cloud fax providers do not offer.

Concord is headquartered in Seattle and primarily serves the US market. Organizations with non-US data requirements should confirm what residency options are available for their specific plan before switching.

‍

6. A Platform That Takes Fax Seriously

Fax may be a legacy technology, but the tools used to manage it do not have to feel that way. Concord's interface reflects the era it was built in: navigating it requires more clicks, more training, and more patience than modern teams expect from a SaaS product.

Fax.Plus is built with a modern, intuitive interface designed for teams that process high volumes of inbound and outbound faxes daily. Sending, receiving, organizing, and routing faxes works the way you would expect it to. For teams that have spent years navigating outdated fax interfaces, the difference is immediate. Fax.Plus has earned PCMag Editors' Choice recognition for its ease of use and modern faxing experience. (PCMag: The Best Online Fax Services)

7. Built for Developers. Ready for Enterprise

Most cloud fax platforms treat the API as an afterthought. Fax.Plus is built API-first, with a REST API that is fully documented, actively maintained, and available on Enterprise plans from day one.

Real-time page-by-page fax streaming is available via webhook, so downstream systems receive and process each page as it arrives rather than waiting for full document delivery. Outbound fax scheduling, retry logic, and delivery status callbacks are standard API features.

The Fax.Plus API documentation is accessible via MCP, enabling AI agents and LLM-based development environments to query API references, find code examples, and retrieve implementation details directly without leaving the development workflow.

For healthcare and enterprise operations teams, fax events can trigger downstream workflows automatically: EHR updates, Slack notifications, document routing, and compliance logging, all without manual intervention.

Concord does not publish a comparable developer API. Organizations building fax into automated workflows should confirm integration options before committing to a platform.

Real-Time Fax Streaming: Why It Matters

In most fax environments, the complete document transmits before anyone can review it. For a 20-page inbound referral packet, the admissions coordinator sees nothing until page 20 arrives. Under line congestion or error conditions, the system queues a full retransmission from the beginning. If several facilities are competing for the same patient simultaneously, batch delivery means you are always waiting.

The Fax.Plus API delivers pages as they arrive, one at a time, in real time. In a competitive referral environment, that architectural difference has direct operational consequences:

• Triage begins minutes earlier per referral
• Bed availability checks happen before competing facilities finish receiving the same document
• A facility with streaming infrastructure can confirm patient acceptance while a batch-delivery facility is still waiting
• At volume, the cumulative effect on referral response times is significant

The feature was built at direct request from an emergency room clinician who needed exactly this capability. It is part of the Enterprise API because it should be.

Based on customer feedback and Alohi's analysis of Concord's product documentation, the standard cloud fax product uses batch delivery. First-page preview is not included in the base product. Concord does not publish its product tier structure publicly, so this is based on evaluation rather than a published rate card.

US Data Residency. Independently Certified.

Alohi's ISO 27001 certification is issued by EY CertifyPoint, one of the most recognized independent certification bodies globally, not a self-attested compliance claim. The full stack covers HIPAA, PCI DSS, GDPR, CCPA, CSA STAR, and Swiss FADP.  All independently verified, with US data residency included as a standard configuration.

Is Fax.Plus the Right Alternative to Concord Fax?

Fax.Plus is the right fit if your organization needs real-time fax processing without add-ons, a compliance stack that goes beyond HIPAA, and data residency in the US or across 20+ global locations.

Healthcare organizations use it to compete on referral intake speed. Legal teams use it to route documents through existing Google Workspace and Slack workflows without custom development. Enterprise teams at companies like Canva, Neuralink, Cloudflare, and PwC use it because the platform is modern, the API is production-ready, and the compliance stack is independently certified across ISO 27001, SOC 2, PCI DSS, and more.

The trial is free, self-serve, and starts immediately. No sales call required.
