What is business fax software?

Business fax software is a cloud-based platform that lets organizations send and receive faxes over the internet — without physical fax machines or dedicated phone lines. It adds enterprise features like team accounts, audit trails, HIPAA compliance, and API integrations that consumer fax apps lack.

What features should enterprise fax software have?

Look for AES-256 encryption, HIPAA compliance with a signed BAA, role-based access controls, audit trails, API access, virtual fax numbers, and integrations with your existing tools (EHR, CRM, email). High-volume plans and number porting are also essential for most enterprise deployments.

How much does business fax software cost?

SMB plans start around $20–$35/month for 400–1,000 pages. Mid-market plans run $35–$100/month for higher volume. Enterprise-tier solutions (OpenText RightFax, eFax Corporate, Concord) use custom pricing based on usage volume, number of users, and compliance requirements.

Is cloud fax software HIPAA compliant?

It can be — but only if the vendor signs a Business Associate Agreement (BAA) and implements required safeguards: AES-256 encryption, access controls, and audit logs. Not every provider offers this. See our [HIPAA fax requirements guide](/blog/hipaa-fax-requirements/) for the full checklist.

Can I keep my existing fax number when switching software?

Yes. Most business fax platforms support number porting. Porting typically takes 5–10 business days. mFax Business, eFax, RingCentral, Fax.Plus, and Nextiva all support it.
