Introduction
eFax & Fax Server Software helps organizations send, receive, route, store, secure, and manage fax documents digitally without relying fully on traditional fax machines. These tools convert fax workflows into cloud, server-based, or hybrid systems where users can send faxes from email, web portals, desktop apps, multifunction printers, or business applications.Fax remains important in industries where document transmission, signatures, compliance workflows, and legacy communication channels are still required. Healthcare, legal, finance, insurance, government, logistics, and enterprise operations often use fax because partners, regulators, or legacy systems still depend on it. Modern eFax and fax server platforms improve fax reliability, reduce paper usage, centralize audit trails, secure document transmission, and integrate faxing into existing business workflows.
Real-world use cases include:
- Sending healthcare and insurance documents

Key evaluation criteria buyers should consider:
- Cloud fax and fax server deployment options
- Inbound and outbound fax reliability
- Email-to-fax and web fax capabilities
- Security and encryption controls
- Audit logs and delivery confirmations
- API and workflow integrations
- Multi-user administration
- Fax number management
- Document storage and routing
- Pricing and fax volume scalability
Best for: Healthcare organizations, law firms, finance teams, insurance companies, government agencies, logistics businesses, enterprises, SMBs, and regulated teams that still depend on fax workflows.
Not ideal for: Fully digital organizations with no fax requirements, very small teams that send only rare one-off faxes, or businesses that can replace fax entirely with secure email, portals, or e-signature workflows.

SMB
SMBs should prioritize ease of use, cloud deployment, email-to-fax, predictable pricing, and basic administration. RingCentral Fax, iFax, SRFax, mFax, and eFax Corporate are suitable options depending on fax volume and support needs.
Mid-Market
Mid-market organizations often need stronger administration, fax number management, APIs, routing, and secure document workflows. eFax Corporate, Concord Cloud Fax, mFax, Biscom Secure Fax, and XM Fax can support growing business fax requirements.

Feature Depth vs Ease of Use
iFax, SRFax, and RingCentral Fax are easier for lightweight faxing. OpenText RightFax, XM Fax, and Biscom Secure Fax provide deeper enterprise controls but require more setup and administration.
Integrations & Scalability
Organizations should prioritize platforms that integrate with email systems, MFPs, document management platforms, APIs, EMR systems, ERP applications, and business workflows. High-volume teams should test routing, delivery confirmations, and fax queue reliability.

Frequently Asked Questions
1. What is eFax and fax server software?
eFax and fax server software allow organizations to send, receive, route, store, and manage faxes digitally. eFax platforms are usually cloud-based, while fax server software may run on internal infrastructure or hybrid environments. These tools replace or modernize physical fax machines and analog phone lines. They help users send faxes through email, web portals, mobile apps, MFPs, or business applications. Organizations use them to improve security, reduce paper use, and centralize fax workflows.
2. Why do businesses still use fax software?
Businesses still use fax software because many industries continue to rely on fax for document exchange, signatures, records, claims, medical documents, legal notices, and legacy workflows. Healthcare, legal, finance, insurance, and government organizations often interact with partners who still require fax. Digital fax tools make these workflows easier and more secure than physical fax machines. They also provide better tracking, delivery confirmations, and administrative control.
3. What is the difference between cloud fax and fax server software?
Cloud fax is hosted by a provider and allows users to send and receive faxes through web portals, email, mobile apps, or APIs. Fax server software is often deployed on internal infrastructure and gives organizations more direct control over fax routing, integrations, and administration. Cloud fax is usually easier to deploy, while fax servers may offer deeper customization for complex enterprises. Hybrid deployments combine both approaches.
4. Are cloud fax services secure?
Cloud fax services can be secure when they provide encryption, access controls, user permissions, audit logs, and secure document handling. Security depends on vendor architecture, configuration, and organizational policies. Regulated industries should carefully evaluate data handling, retention, delivery confirmation, and administrative controls. Cloud fax is often more secure than unmanaged physical fax machines when configured properly.
5. What features matter most in fax software?
Important features include inbound and outbound faxing, email-to-fax, fax-to-email, delivery confirmations, secure routing, audit logs, user administration, fax number management, and document storage. Enterprise teams may also need APIs, MFP integration, workflow automation, high-volume processing, and hybrid deployment options. The right feature set depends on fax volume, compliance needs, and workflow complexity.
6. Can fax software integrate with business applications?
Yes, many modern fax platforms provide APIs and integrations with document management systems, healthcare systems, ERP tools, CRM platforms, email systems, and multifunction printers. These integrations help automate document workflows and reduce manual sending. Enterprise fax platforms are especially useful when faxing is embedded into claims, admissions, billing, legal, or compliance workflows. Buyers should validate integration depth before selecting a platform.
7. Is fax server software better than cloud fax?
Neither is universally better. Cloud fax is easier to deploy and maintain, making it a good fit for SMBs and distributed teams. Fax server software can be better for enterprises that need deep integrations, private infrastructure, high-volume routing, or strict control over fax workflows. Hybrid models are useful when organizations want cloud flexibility while retaining internal workflow control. The best choice depends on security, volume, infrastructure, and compliance needs.
8. How long does implementation take?
Basic cloud fax tools can often be deployed quickly because users only need accounts, fax numbers, and email workflows. Enterprise fax server deployments may take longer due to telephony setup, routing rules, MFP integration, user provisioning, and compliance review. Migration from legacy fax machines or older fax servers may also require planning. Pilot testing is recommended before moving mission-critical fax workflows.
9. What mistakes should buyers avoid?
A common mistake is choosing fax software without understanding monthly fax volume, number management, integration requirements, and compliance needs. Buyers should also avoid selecting lightweight tools for mission-critical enterprise fax workflows. Another mistake is ignoring delivery confirmations, routing rules, and retention policies. Organizations should test real inbound and outbound fax scenarios before full deployment.
10. What are the best alternatives to eFax and fax server software?
Alternatives include secure email, e-signature platforms, document portals, encrypted file sharing, postal mail, and direct system integrations. These alternatives may be better when partners no longer require fax. However, many industries still depend on fax for specific workflows, so alternatives may not fully replace it. The best approach is to modernize fax where required while gradually shifting eligible workflows to more digital channels.
Conclusion
eFax and fax server software remain important for organizations that still depend on reliable document transmission across healthcare, legal, finance, insurance, government, and enterprise operations. The best platform depends on fax volume, deployment preference, compliance requirements, integration needs, and administrative complexity. OpenText RightFax, XM Fax, and Biscom Secure Fax are strong choices for enterprise fax environments that require advanced routing, security, MFP support, and workflow automation. eFax Corporate, Concord Cloud Fax, and mFax are practical cloud fax platforms for organizations modernizing away from fax machines and phone lines. RingCentral Fax, iFax, and SRFax are better suited for SMBs or simpler digital faxing needs. Organizations should shortlist platforms based on real fax workflows, test inbound and outbound delivery reliability, validate integrations with email and business systems, review security and retention settings, and choose the solution that provides the best balance of usability, compliance, scalability, and long-term operational value.
