Fax.Plus is a cloud fax service from Alohi with the broadest free-to-cheap range in the market: a free tier of 10 pages, Basic at $6.99/month for 200 pages, and Premium at $13.99 for 500. For occasional business faxing it is one of the best-value options available. The catch for healthcare is specific and worth knowing before you budget: HIPAA compliance and a signed Business Associate Agreement are available on the Enterprise plan only, at $79.99/month. The API is Enterprise-only too. If you handle PHI, Fax.Plus costs $79.99 to use lawfully — against $25/month for Documo, which includes the BAA on every plan.
Is Fax.Plus HIPAA compliant?
Only on the Enterprise plan. Fax.Plus states that HIPAA compliance with a signed BAA is available on Enterprise ($79.99/month) and no other tier.
That distinction matters more than it sounds, because the free, Basic, Premium, and Business plans are the ones most people find first. Under HIPAA, a covered entity may only disclose protected health information to a vendor that has signed a Business Associate Agreement — see HHS guidance on business associate contracts. Encryption does not substitute for the agreement. A clinic on the $13.99 Premium plan sending patient records is out of compliance even though the transmission itself is protected.
To be fair to Fax.Plus: they do offer it, they do include it at no extra charge on Enterprise, and they say so plainly on the pricing page. This is a tiering decision, not a compliance failure.

Where Fax.Plus is the better choice
For anything that isn’t regulated, Fax.Plus is hard to argue with on price. $6.99 for 200 pages and $13.99 for 500 undercut Documo’s $25 entry, and the free tier is genuinely useful for a one-off.
It suits a solo professional, a small office, or anyone who needs a working fax number and nothing else. If PHI never enters the workflow, the compliance gate is irrelevant and the cheaper plan is simply the better purchase. Documo is not competing for that buyer.
Fax.Plus stops being the economical option at exactly one point: the moment you need a BAA. At that point the price is $79.99, and the comparison changes completely.
Where Documo is different
The BAA is on every plan. Signed and countersigned at no additional cost, from the $25 Solo plan upward. Against Fax.Plus this is the single clearest difference — the compliant entry point is $25 rather than $79.99.
Documo processes the document, not just the transmission. Documo’s intelligent document processing is pre-trained on 20 common healthcare document types — referral forms, prior authorization requests, lab results, insurance cards, discharge reports and more — and combines OCR with AI models to classify each document, extract patient identifiers, and route structured data into a system of record. Human review is supported. IDP is part of Documo’s Custom Platform rather than the standard Cloud Fax plans, so it is a platform decision rather than a $25 add-on.
Named EHR integrations. Open EMR, ModMed, NextGen Enterprise, and PointClickCare, with a fax API for everything else.
Two smaller ones: Documo’s fax eSignatures collect a signature on a faxed document and return it, and the Fax Machine Connector keeps existing fax machines working with no new hardware or phone lines.
What does Fax.Plus cost for a healthcare practice?
$79.99/month, because that is the only plan with a BAA. Compared against Documo:
| Fax.Plus Enterprise | Documo Solo | Documo Business | |
|---|---|---|---|
| Monthly price | $79.99 | $25 | $100 |
| Pages | 1,000+ | 300 | 1,500 |
| Users | Unlimited | 1 | 10 |
| BAA | Yes | Yes | Yes |
| API | Yes | No | Yes |
Read this honestly: at 1,000+ pages with unlimited users, Fax.Plus Enterprise is competitive with Documo Business. The gap is at the low end — a small practice needing a BAA pays $79.99 with Fax.Plus and $25 with Documo.
How do I switch from Fax.Plus to Documo?
Port your fax number so senders do not have to change anything — typically 2–4 weeks depending on the losing carrier, with both numbers live in parallel through cutover. The BAA is executed at signup. If you are on Fax.Plus Enterprise for the API, plan the integration rebuild against the Documo fax API before cutting over; a sandbox environment is available for testing.

Frequently asked questions
Is Fax.Plus HIPAA compliant?
Only on the Enterprise plan at $79.99/month, which includes a signed Business Associate Agreement at no extra charge. The Free, Basic, Premium, and Business plans do not include HIPAA coverage and should not be used for protected health information.
How much does Fax.Plus cost?
As of August 2026: Free (10 pages total), Basic $6.99/month for 200 pages, Premium $13.99 for 500, Business $27.99 for 1,000 with 5 users, and Enterprise $79.99 for 1,000+ with unlimited users. Overage runs from $0.10 down to $0.03 per page by tier.
Does Fax.Plus have an API?
Yes, on the Enterprise plan only. Lower tiers do not include programmatic access.
Who owns Fax.Plus?
Fax.Plus is a product of Alohi.
Is Fax.Plus cheaper than Documo?
For non-regulated faxing, yes — $6.99 and $13.99 both undercut Documo’s $25 entry plan. For HIPAA-covered faxing, no: Fax.Plus requires the $79.99 Enterprise plan while Documo includes the BAA at $25.
What is the best Fax.Plus alternative for healthcare?
A provider that includes a BAA at an entry price. Documo includes one on every plan from $25/month with SOC 2 Type II certification. WestFax also signs a BAA on every plan starting at $14.95 and is worth comparing if cost is the deciding factor.
Does Documo have a free plan?
No. Documo offers a free trial rather than a permanently free tier. If you need occasional free faxing and handle nothing regulated, Fax.Plus’s free tier is the better fit.
Can I keep my fax number if I switch from Fax.Plus?
Yes. Fax numbers port between providers, typically in 2–4 weeks, with both numbers live in parallel during the transition.
Bottom line
Choose Fax.Plus for inexpensive, non-regulated faxing, or if you need a free tier. On price alone below the HIPAA threshold it wins.
Choose Documo if you need a BAA without paying $79.99 for it, if you run Open EMR, ModMed, NextGen Enterprise, or PointClickCare, or if the real cost is the manual work created by documents arriving rather than the faxing itself.
