Which one is for you
Pick eFax if
- Fits if you fax within the US and Canada and want it all in your email
- Works for small medical offices that want a signed BAA on a plan bought online, which is Business
Look elsewhere if
- Skip it if you fax abroad on Personal, which covers pages to the US and Canada only
- Pricey if you need a signed BAA, which Personal lacks; Business is $33.33 a month billed yearly
- Not for you if you want a desktop app on a Mac, as the print-to-fax app is Windows only
- Watch out: extra pages are 10 cents on Personal and 7 cents on Business, and international rates vary by country
- Watch out: on Business, extra users are $10 a month and extra numbers $5, and the API needs Corporate, priced by sales
Pick Sfax if
- Fits if your medical office needs an audit trail on every fax
- Works for practices that fax from desktop programs through a print driver
Look elsewhere if
- Not for you if you want to see a price first, as none could be read from Sfax's pages
- Watch out: the trial is a paid plan you must cancel within 14 days, and monthly plans need 30 days' notice to cancel
- Skip it if you use Android, or Windows older than 11, as neither is supported
- Tight if you need several lines, since plans include one toll-free line and each extra is $5 a month
How we grade them

|---|---|---|
| Value for money | CPersonal is $15.83 a month billed yearly ($18.99 monthly) for one number and 200 pages, past the start of this category's dearer quarter at $14.95. Faxing abroad and a signed BAA need Business at $33.33. | CNo price is on record. Sfax's pages turned our reader away and its help centre lists none, so there's nothing to set against the field. Each extra line is $5 a month, or $48 a year on annual plans. |
| Free plan and trial | CA 7-day trial of Personal with up to 200 pages, and no free plan after it. The listing doesn't say whether the trial takes a card. | DThe 14-day trial means signing up to a paid plan and cancelling within 14 days to avoid the charge. After that there are no refunds or part months. |
| Features | BEmail to fax, local, toll-free or transferred numbers, a Windows print-to-fax app, phone apps with e-signing and searchable storage on every plan, with an API on Corporate. That covers the job, split across its plans. | BA web app with folders and a library, print-to-fax on Windows and Mac, annotating and signing, an audit trail on each fax, admin controls with SSO, an API with callbacks, and Box and ShareFile. That covers the job. |
| Ease of use | BNo store rating on record. Email to fax is on every plan, so you send by attaching a document to an email, and the apps are there if you want them. | CNo store rating on record. You install a print driver to fax from other programs, and admins set up users, lines, permissions, IP safelists and SSO. |
| Platforms and integrations | AWeb, Windows, iPhone and Android, with Dropbox, Google Drive and Epic, and a REST API on Corporate. There's no Mac app, and the API is only on the plan sold through sales. | BWeb, Windows 11, Mac and iPhone, with an API, Box, ShareFile and SSO through Okta, Entra ID, Google Workspace and others. There's no Android app, which keeps it off the top grade. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
