Does Sfax Plus or WestFax Solo cost less for one person at 500 pages?

At 500 pages, the lowest WestFax plan with a BAA is Solo at $14.99 a month with no annual option, while the lowest Sfax plan with a BAA is Plus at $56.83 billed annually, so WestFax costs less. Both plans carry a BAA, which leaves the monthly price as the difference. The table compares the cheapest plan with a BAA at 500 pages a month for one person.

Because WestFax has no annual billing, the like-for-like Sfax price is $62.00 month to month, still above $14.99. Over a year, WestFax Solo comes to $179.88, while Sfax Plus comes to $681.96 billed annually and $744.00 month to month. Annual billing at Sfax earns one month free.

Does WestFax stay cheaper than Sfax with a BAA at 1,000 pages?

WestFax stays cheaper than Sfax at both volumes, with Solo at $14.99 and $29.99 month to month against Sfax Plus at $56.83 and $86.83 billed annually. The table shows the cheapest plan with a BAA for one person, as a price a month, at 500 and 1,000 pages sent and received.

Sfax Plus costs $62.00 month to month at 500 pages and $92.00 at 1,000 pages, the like-for-like comparison with the monthly-only WestFax prices. Over a year at 1,000 pages, WestFax Solo comes to $359.88, against $1,041.96 for Sfax Plus billed annually and $1,104.00 month to month.

Does Sfax or WestFax cost less for five people who need a BAA?

WestFax costs less for five people, at $39.95 a month on Team at both 500 and 1,000 pages, month to month, against $56.83 and $86.83 a month billed annually for Sfax Plus. The table shows the cheapest plan with a BAA for 5 people, as a price a month, at 500 and 1,000 pages sent and received.

WestFax Team includes 5 users and 1,500 pages in a single price, so the figure holds at both volumes. A team of five fits those five users, so the Team 3,000 step does not apply. Sfax lists unlimited users on all of its plans, which is why Sfax Plus costs the same for five people as for one.

Over a year, the team comes to $479.40 on WestFax Team at either volume, against $681.96 at 500 pages and $1,041.96 at 1,000 pages for Sfax Plus billed annually, or $744.00 and $1,104.00 month to month.

Which Sfax and WestFax plans include a BAA?

In the BAA column, Sfax reads "Included on Plus and up" and WestFax reads "Included on every plan". The Standard card on Sfax carries no BAA line, while Plus, Contender and Enterprise print "BAA Available". The table shows how each provider handles the BAA and the people each plan includes.

A Sfax practice on Standard has to move up to Plus to get a BAA, and WestFax needs no such step, since every WestFax plan from Solo up comes with one. A WestFax practice that grows from Solo to Team keeps its BAA through the move. A Sfax practice that adds users stays on Plus and keeps its BAA, because users are unlimited on every Sfax plan.

Does Sfax or WestFax limit how many people can share a plan?

Sfax lists unlimited users on all of its plans, while WestFax Solo takes one user, Team includes 5 users and Team 3,000 includes 25.

On WestFax, the second user brings Team ($39.95, with 1,500 pages) and the sixth brings Team 3,000 ($69.99). Sfax Plus stays at $56.83 billed annually or $62.00 month to month at 500 pages however many users it has. A one-person practice does not need the unlimited users, since WestFax Solo covers one user at $14.99 a month.

A practice that expects its headcount to grow can compare unlimited-user HIPAA fax plans.

What fees do Sfax and WestFax add beyond the plan price?

A number ported into WestFax costs a one-time $20 charge, and every extra WestFax number carries a $20 setup fee on top of $4.95 a month, while Sfax bills overage at 10 cents a page on every plan. Sfax overage applies to pages beyond a plan, and Sfax Plus is the plan priced in every table above.

Who should switch between Sfax and WestFax, and to which plan?

WestFax is the switch for a practice of up to five users: Solo for one person and Team for up to five both cost less than Sfax in every price table above.

One person on Sfax Plus at $62.00 month to month would pay $14.99 on WestFax Solo, and five people on Sfax Plus would pay $39.95 on WestFax Team. A team of 6 to 25 users would pay $69.99 on WestFax Team 3,000, which is more than Sfax Plus costs at 500 pages.

A practice on the Sfax Standard card, which lacks the BAA line, gets a BAA at 500 pages from WestFax Solo at $14.99 a month, against $56.83 billed annually for Sfax Plus. The move trades unlimited users for WestFax tiers of 1, 5 and 25 users, so headcount decides whether the switch pays.

No plan in these tables has a lower price than Fax Pigeon Standard, which is $9.99 a month billed annually for 500 pages.
