Fax.Plus vs Sfax (2026): which should you pick?

Pick Fax.Plus if

• Fits if you fax a few hundred pages a month from email or your phone
• Works for small teams that want shared fax numbers under one admin

Look elsewhere if

• Skip it if you want to receive faxes free, as the free account sends 10 pages in total and has no number
• Pricey if you need a signed HIPAA BAA, the API or Zapier: all three are on Enterprise, from $79.99 a month billed yearly
• Tight if you send long documents on Basic, which caps a fax at 60 pages and charges 10 cents a page over 200
• Watch out: porting a US or Canadian number and toll-free numbers start on Premium at $13.99 a month billed yearly
• Watch out: numbers beyond the two on Business are $4.99 a month each, and picking a specific number is $19.99 once

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

Fax.Plus

• The free account has 10 pages in total and cannot receive faxes; a paid plan is needed for a number.
• Fax.Plus says HIPAA compliance with a signed BAA is available on the Enterprise plan only.
• The API and Zapier integration are listed only under Enterprise, which starts at $79.99 a month billed annually.
• Extra numbers cost $4.99 a month each beyond the two on Business and Enterprise; choosing a specific number is a one-time $19.99.

Sfax

• Prices could not be read: the Sfax pages on scrypt.com turned away automated reading, and the help center lists no prices.
• Plans include one toll-free line; each extra line is $5 a month on monthly plans or $48 a year on annual plans.
• Cancelling a monthly plan needs 30 days' notice by support ticket or email, with no refunds or partial months after the first 14 days.
• The Windows app supports only Windows 11 on x64 or x86, and the help center lists an iPhone app but no Android app.
