eFax vs Fax.Plus for HIPAA faxing

$33.33 a month, billed annually, is what the cheapest eFax plan with a BAA costs for one person handling 500 pages a month. Fax.Plus asks $79.99 a month, billed annually, for its cheapest plan with a BAA, so eFax costs less for any practice of up to five people that needs one.

Which eFax and Fax.Plus plan costs least with a BAA?

eFax Business costs least with a BAA, at $33.33 a month billed annually, against $79.99 for Fax.Plus Enterprise, the cheapest Fax.Plus plan that carries one. Both figures assume one person and 500 pages sent and received each month. On month-to-month billing, eFax Business costs $39.99 and Fax.Plus Enterprise costs $99.99, so annual billing is the lower price on both sides.

A practice that needs a BAA cannot use eFax Personal or Fax.Plus Basic, Premium or Business, because none of them carries one. That is why the comparison starts at eFax Business and Fax.Plus Enterprise.

The table compares the cheapest plan with a BAA at 500 pages a month for one person.

Which costs less at 500 and 1,000 pages, eFax or Fax.Plus?

eFax costs less at both volumes: $33.33 a month billed annually for 500 pages and $54.16 for 1,000 pages, against $79.99 for Fax.Plus Enterprise at either volume. Fax.Plus Enterprise covers 4,000 pages, so its price does not move between the two volumes. Across a year on annual billing, eFax comes to $399.96 at 500 pages and $649.92 at 1,000, against $959.88 on Fax.Plus at either volume.

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.

On eFax the plan name stays Business at both volumes and only the price moves, from $33.33 to $54.16. Fax.Plus Enterprise is the only Fax.Plus plan with a BAA, so a practice at 500 pages still buys the plan that covers 4,000 pages and unlimited members.

On month-to-month billing the order holds. A year at 500 pages comes to $479.88 on eFax Business and $1,199.88 on Fax.Plus Enterprise, and a year at 1,000 pages comes to $779.88 on eFax Business against $1,199.88 on Fax.Plus Enterprise.

What do eFax and Fax.Plus charge for pages over the plan?

eFax Business charges 7 cents for each page over the plan, and Fax.Plus Enterprise charges 3 cents for each page past its 4,000. A practice at 500 or 1,000 pages sits inside the Fax.Plus allowance, so the Fax.Plus figures in the tables carry no page charge. For each eFax plan and its page charges, see eFax pricing, plan by plan.

How do eFax and Fax.Plus provide a BAA, and on which plans?

eFax prints its BAA on the Business plan card and includes it on Business and up, while Fax.Plus includes its BAA on Enterprise only. A business associate agreement, or BAA, is the contract a covered practice signs with any vendor that handles its protected health information. Both prices in this comparison already include the BAA, so no separate fee sits on top. For the full answer on Fax.Plus, see whether Fax.Plus is HIPAA compliant.

How many users do eFax Business and Fax.Plus Enterprise include?

eFax Business includes 5 users, with each extra user at $10 a month or $100 a year on annual billing, while Fax.Plus Enterprise includes unlimited members. Adding people therefore never changes the Fax.Plus Enterprise price. Five people pay the same as one on either plan: $399.96 a year on eFax Business and $959.88 a year on Fax.Plus Enterprise at 500 pages on annual billing. A practice of six or more pays the extra-user fee on eFax for each person past five.

For one person, neither user rule touches the bill, so the plan price alone sets the gap.

What does eFax charge to port a number in or out?

eFax charges a $40 fee per number to port a number in and an administrative fee of $40 per number to port out, both set out in its Customer Agreement. Each number that moves carries its own fee, so a practice moving two numbers pays for both moves.

A practice moving a number from Fax.Plus to eFax pays eFax's $40 port-in fee on each number, and a practice moving a number from eFax to Fax.Plus pays eFax's $40 administrative fee on each number that leaves.

This comparison lists no Fax.Plus porting fee, so the two cannot be set against each other on that line. Check Fax.Plus's own terms before a number moves.

Who should switch from Fax.Plus Enterprise or eFax Business?

A practice paying Fax.Plus Enterprise or eFax Business for a BAA should switch to Fax Pigeon Standard, which costs $9.99 a month billed annually for one person on 500 pages, the lowest figure with a BAA in the first table. Every Fax Pigeon plan carries a signed BAA from signup and unlimited people, and porting is free.

Over a year on annual billing at 500 pages, Fax Pigeon Standard costs $119.88, against $399.96 for eFax Business and $959.88 for Fax.Plus Enterprise. The gap is $23.34 a month against eFax Business and $70.00 a month against Fax.Plus Enterprise.

At 1,000 pages on annual billing, Fax Pigeon Plus costs $203.88 a year, against $649.92 for eFax Business and $959.88 for Fax.Plus Enterprise. That is $37.17 a month less than eFax Business and $63.00 a month less than Fax.Plus Enterprise. On month-to-month billing at 500 pages, the monthly gaps are $28.00 against eFax Business and $88.00 against Fax.Plus Enterprise.
