eFax vs MetroFax for a Small Medical Office

Disclosure: Fax Ledger earns affiliate commissions from CJ partners including eFax and MetroFax at no extra cost to you. We did not physically test these services; all comparisons are based on published pricing, vendor documentation, and aggregated user reviews.

A small medical office that still relies on fax — referral forms, lab results, prescriptions, insurance authorizations — faces a specific set of requirements that most general online fax comparisons skip over. You need a reasonable monthly page allowance, a price point that fits a lean practice budget, and, critically, clarity on whether the vendor will sign a Business Associate Agreement (BAA) as required under HIPAA.

This comparison covers eFax and MetroFax on the factors that matter most to a small medical office: published plan pricing, included page allowances, overage costs, HIPAA and BAA positioning, and what aggregated user reviews say about reliability. We did not subscribe to or personally test either service; every figure below comes from each vendor's published pricing pages and compliance documentation, supplemented by aggregated user review data.

Quick Verdict

• eFax is better positioned for a medical office that wants an established brand name, a clear upgrade path to a BAA-covered business plan, and a larger ecosystem of support.
• MetroFax tends to appeal to budget-focused small practices that want a higher included page count at a lower monthly rate and do not yet require a formally signed BAA.

Plan Pricing at a Glance

Prices are based on published vendor pricing pages and are subject to change. Always confirm current pricing directly with the vendor before subscribing.

eFax: What the Published Specs Show

eFax is one of the longest-running online fax brands, operating since 1996. Its Plus plan is marketed primarily at individual professionals and light-volume users, while its Business offering is aimed at teams and organizations that need multi-user accounts, admin controls, and HIPAA compliance infrastructure.

For a small medical office, the critical distinction is the BAA tier. According to eFax's published compliance documentation, a signed Business Associate Agreement is available on Business plans, not on Plus. A solo practitioner or a two-physician practice that operates under HIPAA must confirm they are subscribing to the correct tier and receiving a countersigned BAA before transmitting any protected health information (PHI).

The Plus plan's 150-page monthly allowance is tight for a busy practice. A single busy clinic day can generate 20–30 fax pages in referral documentation alone. The overage rate of approximately $0.10 per page means a practice exceeding its allowance by 100 pages pays roughly $10 extra that month — a manageable figure, but one worth modeling against your actual fax volume.

Aggregated user reviews of eFax highlight strong brand recognition and generally reliable delivery, with common complaints centering on the billing process when downgrading or canceling and occasionally slow customer support response times.

MetroFax: What the Published Specs Show

MetroFax positions itself as a value-priced online fax service for small businesses. Its published standard plan includes up to 500 pages per month at roughly $12.95/month — a substantially higher page budget at a lower price point than eFax's Plus tier.

The trade-off, and it is an important one for a medical office, is that MetroFax does not prominently feature a signed HIPAA BAA in its published marketing materials at the standard plan level. A practice that transmits PHI and needs HIPAA documentation should directly contact MetroFax to ask about BAA availability and terms before subscribing, rather than assuming compliance based on standard plan features.

On the features side, MetroFax supports faxing via email (send by attaching a PDF, receive faxes as email attachments), a web portal, and a mobile app. Number porting is available per published documentation, which matters for a medical office that has a published fax number on referral directories and insurance provider panels — changing that number is a significant administrative burden.

Aggregated user reviews of MetroFax are mixed, with positive notes on value pricing and straightforward setup, and recurring complaints about customer support responsiveness and occasional fax delivery failures on the receiving side.

HIPAA and BAA: The Most Important Factor

For any healthcare provider covered under HIPAA, transmitting patient fax documents through a third-party service means that service is handling PHI on your behalf. Under HIPAA rules, you must have a signed BAA in place with any Business Associate — including your online fax provider.

What to look for in a vendor BAA:

• Confirmation that the BAA is signed and countersigned (not just a clickwrap acceptance)
• Specification of which plan tier receives BAA coverage
• Language addressing encryption in transit and at rest
• The vendor's breach notification commitments

Based on published documentation, eFax Business plans include a signed BAA. MetroFax's BAA posture at standard plan tiers is not clearly documented in public-facing materials at the time of this writing. A small medical office should treat any fax vendor's HIPAA claim with due diligence — request the actual BAA document before transmitting any PHI.

Page Volume: Which Plan Fits a Small Practice?

A useful framework for estimating your monthly page volume:

• Under 150 pages/month: Solo practitioner with minimal referral traffic → eFax Plus may suffice
• 150–500 pages/month: 2–5 provider practice → MetroFax standard or eFax Plus with overage buffer
• 500+ pages/month: Busy multi-specialty or group practice → eFax Business or enterprise-tier plan

The key error to avoid: underestimating volume and getting hit with per-page overages on a tight plan. Both vendors charge per-page overage fees beyond the included allowance.

Ease of Setup and Integration

Both eFax and MetroFax offer email-to-fax workflows that require no special hardware. Setup involves choosing a plan, selecting or porting a local fax number, and configuring fax delivery to an email address. Neither service requires installing software on office computers, though both offer web portals and mobile apps.

For a small medical office using an EHR system, native fax integration typically requires the EHR's own fax module rather than a consumer online fax service. Online fax services at this tier are generally most useful for ad-hoc sending and receiving rather than deeply integrated EHR fax workflows.

Cost Comparison: 12-Month Scenario

Overage estimates based on published per-page rates. Actual costs depend on current pricing and any promotional rates applied at signup.

MetroFax's higher included page count makes it notably more cost-effective for a practice that regularly sends 200–400 pages per month and does not require a BAA. For HIPAA-mandated BAA coverage, the cost comparison shifts significantly toward eFax's business tier, which is priced by negotiation.

Who Should Choose eFax?

A small medical office should lean toward eFax if:

• You need a formally signed BAA and want an established vendor with documented HIPAA infrastructure
• Your monthly volume is under 150 pages and you want a recognizable brand
• You anticipate scaling to a multi-user team and want a clear upgrade path

Who Should Choose MetroFax?

A small medical office (or a non-covered entity adjacent to healthcare) should consider MetroFax if:

• Your monthly volume regularly exceeds 150 pages and you want to avoid per-page overages
• You are cost-sensitive and can verify BAA availability directly with the vendor
• You primarily need email-to-fax workflows without complex admin controls

Bottom Line

For a small medical office operating under HIPAA, the BAA question is not optional — it is a compliance requirement. Based on published documentation, eFax Business plans offer the clearer HIPAA pathway. MetroFax offers better value on page count and monthly pricing but requires direct vendor verification on BAA terms before use with PHI.

Before subscribing to either service, verify current pricing on the vendor's site, confirm BAA availability in writing, and model your actual monthly page volume to avoid overage surprises.
