mFax: pros and cons
What they do well
- HIPAA compliance on every plan, with a BAA available by request
- An API for developers, SSO at Enterprise, and EHR integrations
- SOC 2 Type II and a published inbound-routing SLA
- High-volume plans available
Where FaxTerra wins
- No free tier and nothing below the Solo plan
- Solo is annual-billing only: their pricing page shows "$25/mo billed annually" under both the monthly and yearly toggles, so the entry price is $300 up front
- The BAA is an email-and-return process rather than something you sign at checkout
- A page is defined as 60 seconds of transmission, and a slower page may be charged as more than one
The verdict
Documo is the credible healthcare specialist, and on scale and integration depth it is stronger than us. On the small-practice comparison the numbers are close and the terms are not: their Solo tier carries 300 pages a month and our Business plan with HIPAA compliance carries 200, we are $14.98 against their $25, and theirs is annual-billing only at $300 up front where ours bills monthly. Their BAA is emailed, signed and returned; ours is executed inline at checkout.
