How do Fax.Plus and Sfax sign a BAA, and on which plans?

Fax.Plus includes a BAA on its Enterprise plan alone, and Sfax includes one from Plus upward.

Basic, Premium and Business, the other Fax.Plus plans, come without a BAA, which leaves Enterprise as the only Fax.Plus choice for a practice that needs one. Sfax carries the BAA Available line on three cards, Plus, Contender and Enterprise, and leaves it off Standard, so Plus is where a BAA starts.

The table shows how each provider handles the BAA and the people each plan includes.

ProviderBAAHow the BAA is signedUsers included
Fax.PlusIncluded on Enterprise onlyEnterprise plan onlyUnlimited members on Enterprise
SfaxIncluded on Plus and upBAA Available printed from Plus upUnlimited
Fax PigeonIncluded on every planSigned at signupUnlimited

The table marks Fax.Plus as Included on Enterprise only and Sfax as Included on Plus and up. At both providers the BAA is part of the plan, so the prices in the tables already include it.

The practical difference is the entry price. A practice that needs a BAA at Fax.Plus must buy Enterprise, a 4,000-page plan, even when it sends and receives only 500 pages a month, while a practice at Sfax can start at Plus, which is $56.83 a month billed annually at 500 pages.

The HIPAA question for each provider is answered in whether Fax.Plus is HIPAA compliant and whether Sfax is HIPAA compliant.

How many people do Fax.Plus and Sfax plans include?

Fax.Plus Enterprise has unlimited members, and every Sfax plan allows unlimited users.

A five-person practice pays the one-person price on either plan: $56.83 a month billed annually at Sfax Plus and $79.99 at Fax.Plus Enterprise, at 500 pages. Neither plan caps users, so a practice that adds staff keeps the same price on either one.

What do Fax.Plus and Sfax charge for extra pages, extra numbers and porting?

Past its 4,000 pages, Fax.Plus Enterprise charges 3 cents for each extra page, while Sfax charges 10 cents for each overage page on every plan, and no porting or extra-number price is listed here for either provider.

Fax.Plus charges the lower rate per extra page, 3 cents against 10 cents at Sfax. At 500 and 1,000 pages a month, a Fax.Plus Enterprise practice sits well inside the plan's 4,000 pages, so that rate does not apply at either volume compared here.

The Sfax Plus price rises between 500 and 1,000 pages, and no page allowance for Plus is listed here, so ask Sfax what Plus includes at 1,000 pages.

Who should switch from Fax.Plus or Sfax, and to what?

Practices on Fax.Plus Enterprise at 500 pages should switch to Sfax Plus, which costs less on both billing terms. A practice already on Sfax Plus at 500 pages would pay more at Fax.Plus Enterprise on either billing term.

At 1,000 pages the answer depends on billing. A practice paying Fax.Plus Enterprise month to month saves by moving to Sfax Plus, from $99.99 to $92.00, while a practice paying annually would pay more, from $79.99 to $86.83.

Which services can replace Fax.Plus covers the options beyond these two. In these tables the lowest-priced option is Fax Pigeon Standard, which costs $9.99 a month on annual billing.
