How do SRFax and Sfax sign a BAA, and on which plans?

A practice gets a BAA from SRFax by asking for one through the Request a BAA link under the Healthcare plans, and gets one from Sfax by choosing Plus or a higher plan.

Sfax lists BAA Available for Plus, Contender and Enterprise and omits it from Standard, which makes Plus the entry plan for a BAA.

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

SRFax's entry reads On request, so the practice asks first and SRFax then provides the agreement. Sfax's entry is Included on Plus and up, so the agreement comes with the plan.

The two routes ask different things of a practice. SRFax lists no price for the BAA, so a practice should ask SRFax what the agreement adds before it compares totals. At Sfax the BAA comes with the plan tier, so the Plus price already includes it.

Sfax's HIPAA position is covered in whether Sfax is HIPAA compliant.

How many people do SRFax and Sfax plans include?

Every SRFax Healthcare plan comes with multiple user accounts, while Sfax gives each plan unlimited users.

The phrase multiple user accounts gives no number, and no price for an extra SRFax user is listed here. Sfax has no extra-user cost to ask about, because its users are unlimited.

A five-person practice pays the prices already shown: $13.65 a month at SRFax Healthcare Basic and $56.83 at Sfax Plus for 500 pages, billed annually. Headcount does not change which provider costs less.

What does it cost to port or add a number at SRFax or Sfax?

SRFax charges $25 one time to port in a local number and $4.95 a month for each additional fax number, while no Sfax charge for porting or extra numbers is listed here.

A practice moving its local number from Sfax to SRFax pays the $25 once, while each extra number adds $4.95 every month to the SRFax bill. The $25 is small beside the price gap, since Sfax Plus costs more than SRFax Healthcare Basic by more than $25 every month at 500 pages, on annual and month-to-month billing alike.

Sfax bills 10 cents a page for pages beyond a plan's allowance, on every plan. SRFax's price for an extra page is not listed here, so ask SRFax for it.

Who should switch from SRFax or Sfax, and to what?

A practice on Sfax that needs a BAA should switch, because Sfax has the highest price in the tables at 500 pages and at 1,000. Sfax Plus runs $56.83 and $86.83 a month billed annually, against $13.65 and $29.50 at SRFax. A practice already on SRFax would pay more at both volumes by moving to Sfax. An SRFax practice that grows from 500 to 1,000 pages moves up to Healthcare Basic Plus at $29.50 a month billed annually, which is still below the $56.83 a Sfax Plus practice pays at 500 pages.

A practice moving from Sfax to SRFax should first ask SRFax how many user accounts its Healthcare plans allow and what an extra user costs, since Sfax gives unlimited users and SRFax lists only multiple.

More choices than these two are covered in which services can replace SRFax. Fax Pigeon Standard is the lowest-priced option in these tables, at $9.99 a month billed annually.
