Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.8
GPA, above 0 of the 10 other online fax services we grade
Documo, launched as mFax in 2017, is a cloud fax service built mainly for healthcare. Faxes are sent and received in a browser, by email, from a printer or an analog fax machine connector, and through a REST API, with a signed BAA on every plan. Add-ons sort, read and route incoming faxes with AI and connect them to electronic health records.
To get you started, here are 9 things to know about Documo, taken from its own pages and our grades.
No store rating on record, and no app to install: you fax in a browser, by email, or through a printer or analog machine you connect.

- 7
Cloud Fax API
A REST API with webhooks sends and receives faxes, generates cover pages and reports delivery status. API access is listed from the Business plan.

That is against the other online fax services we grade, on value, the free plan, features, ease of use and platforms.
- 9

To replace Documo you would be making fax numbers connected to the phone network. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for HIPAA fax for clinics, with a BAA on every plan
Documo, once mFax, is cloud fax for healthcare with a signed BAA on every plan, a REST API from Business up and an add-on that reads and routes incoming faxes. It starts at $25 a month billed yearly for 300 pages, there are no phone or desktop apps, and faxes are only kept for 1 year.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Solo is $25 a month billed yearly for one user and 300 pages, with no monthly price shown, which puts it in this category's dearest tenth. The BAA is included, where eFax wants Business at $33.33 for one. |
| Free plan and trial | C | A 14-day trial with no credit card needed, and extensions through sales. No free plan after it. |
| Features | C | Browser, email, print and analog-machine faxing, numbers and porting, a BAA on every plan, an API from Business and AI reading as an add-on. The gaps: faxes are kept for 1 year, and the AI add-on is priced by sales. |
| Ease of use | C | No store rating on record, and no app to install: you fax in a browser, by email, or through a printer or analog machine you connect. It's built to plug faxes into clinic systems. |
| Platforms and integrations | C | Web only, with no phone or desktop app. A REST API with webhooks starts on Business at $80 a month, no ready-made integrations are listed, and EHR links are on the custom plan. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Documo is for
- Fits if you run a clinic or practice and need a signed BAA on even the smallest plan
- Works for healthcare software teams building fax into their own product through an API
Who it is not for
- Pricey if you're one person, as Solo is $25 a month billed yearly for 300 pages, with 15 cents for each extra page
- Skip it if you want to fax from a phone or desktop app, as none is listed
- Watch out: faxes are kept for 1 year on Solo, Business and Enterprise
- Not for you if you want the API on Solo, as it starts on Business at $80 a month billed yearly
- Watch out: the AI add-on is priced per document by sales, and the FAQ gives Enterprise as $250 a month, not the $240 shown
Good to know
Good for

- AI document processing is billed per document as an add-on and priced through sales.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Documo you would be making fax numbers connected to the phone network. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 10 of the 10 other online fax services grade higher. It costs $300 a year.
What you could not
- Fax numbers connected to the phone network.
- An API that other software can build on.
- AI features, unless you pay a model provider for each request yourself.
- What a company asks for before it lets staff use something: SOC 2, HIPAA and audit logs.
What this rests on. Documo’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
