One platform vs separate phone, fax and texting vendors: the 3-year cost

What does “separate vendors” mean for a practice?

Separate vendors means the office pays three companies for three channels that patients experience as one practice.

A typical small-practice stack looks like this. A general business phone system carries calls and voicemail, priced per user. A healthcare texting app carries two-way patient texting, priced per user or per practice, because the phone system’s texting is either capped, outside its BAA or not registered for patient use. A fax service, online or a dedicated line, carries referrals and records, because the phone system either does not include fax or sells it as an add-on.

Each vendor has a seat price, a setup fee, a contract term, a renewal date and, where PHI is involved, a Business Associate Agreement. Each one also bills regulatory fees and taxes on its own lines. The hidden costs guide covers those charges in detail.

A unified platform collapses the three into one account, one number, one record per patient and one agreement. What a unified communications platform is explains the structure. This article does the arithmetic.

What goes into a fair 3-year total?

A fair total counts every charge the office will pay over 36 months, not just the recurring seat price.

1. Recurring charges × 36. Seat prices for every seat, plus per-practice or per-user add-ons for texting and fax.
2. One-time charges. Setup or implementation fees, SMS registration, hardware.
3. Regulatory fees and taxes. Federal USF charge, state and local 911 fees and telecom taxes, billed per vendor and per line. These vary by state and are excluded from both sides below, but they multiply with the number of vendors.
4. Exit exposure. Early-termination fees and auto-renewal on annual terms. These are zero on month-to-month plans.

Two rules keep the comparison honest. Competitor figures appear only through the dataset, with source and check date, so nothing is retyped. Where a vendor publishes no price, the line says “quote” and the total is left open rather than guessed.

What does a 5-seat office pay on one platform?

On ZentryVoice, a 5-seat office with texting, eFax, two desk phones at the front desk and the Technical Support plan is computed from the published price list as follows.

• Monthly recurring: $150, made up of 5 seats at $20, texting at $15 per practice, eFax at $15 per practice and Technical Support at $20 for up to 8 extensions.
• One-time: $488 for two desk phones at $119 each.
• First year: $2,288.
• 3-year total: $5,888.

Without desk phones or a support plan, the same office pays $130 per month and $4,930 over 3 years. Regulatory fees and taxes are excluded. There is no annual term, so exit exposure is zero.

What does the same office pay across separate vendors?

The separate-vendor side is built from the dataset, with each assumption labelled. Two stacks are shown, because practices build them two ways.

Stack A: a general phone system plus a healthcare messaging platform

The phone system is Nextiva’s Core tier on monthly billing at $23 per user per month (published, checked 2026-10-13), chosen because Nextiva publishes its prices and executes a BAA covering phone service and its fax product. Core includes 100 texts per user per month, but Nextiva’s HIPAA accounts disable visual voicemail, voicemail-to-email and email-to-fax, and online fax is listed as an add-on with no published price.

Texting and fax come from Spruce Health’s Basic tier at $24 per user per month (published, checked 2026-10-13), which includes secure patient texting, eFax and a BAA, plus a one-time SMS registration fee of $19.50 (one-time SMS registration fee per organization (vendor page); desk-phone hardware billed separately, checked 2026-10-13). Spruce Basic does not include VoIP phone service, which is why the phone system is still needed.

Assumptions, stated plainly. All 5 staff get a Nextiva seat. All 5 also get a Spruce seat, because the front desk, the clinicians and the office manager all read and send patient texts. An office that gives only 2 staff access to texting would buy 2 Spruce seats instead. Desk phones are excluded from this stack, because Nextiva sells them separately with no price in the dataset. Regulatory fees and taxes are excluded, as on the ZentryVoice side, but note that Spruce passes telecom taxes through and Nextiva bills them per line as well.

The arithmetic. Monthly recurring = 5 × $23 per user per month (published, checked 2026-10-13) + 5 × $24 per user per month (published, checked 2026-10-13). The 3-year total = that monthly figure × 36 + $19.50 (one-time SMS registration fee per organization (vendor page); desk-phone hardware billed separately, checked 2026-10-13). Nextiva’s monthly rate carries no term; its lower annual rate would need a 12-month commitment and would lower the total by roughly a third on the phone line while adding exit exposure.

Stack B: a phone system plus a standalone texting app plus a standalone fax service

Many practices use a phone system with no healthcare texting at all, a standalone HIPAA texting app and a separate online fax account or analog fax line. The phone system is again $23 per user per month (published, checked 2026-10-13) for 5 seats. The texting app and the fax service are quote. The HIPAA-focused standalone vendors in this category either do not publish prices or are not yet in the dataset, and this guide does not invent figures. Each adds its own monthly fee, its own setup or registration fee, its own regulatory lines and its own BAA. An analog fax line adds a second carrier bill and its own 911 and USF charges.

Stack B therefore has a floor, the phone system alone, and no ceiling until the quotes arrive. Its 3-year total is at least 5 × $23 per user per month (published, checked 2026-10-13) × 36 before any texting or fax charge.

The dataset view at 5 seats

Estimates use each vendor's lowest published tier for 5 seats; per-location prices are divided by seats. Bundles differ: add-ons, SMS volume and BAA eligibility are listed per vendor, and "reported" means the figure comes from a third-party source pending confirmation on the vendor's page. See the Practice Phone Price Index for the method.

The table shows why seat price alone misleads. RingCentral and Nextiva list lower annual-term seats than ZentryVoice, but texting allowances are capped, fax may be an add-on and HIPAA mode disables features. Spruce includes texting, fax and a BAA but not phone service. Weave bundles everything per location, which suits larger offices and penalizes 5-seat ones, as the per-user versus per-location guide shows.

How do the two setups compare side by side?

Three conclusions follow. First, the one-platform total is lower than Stack A when every staff member needs texting access, and roughly level with it when only two do. That is before the separate vendors’ extra regulatory lines and management time are counted. Second, Stack B cannot be totalled without quotes, which is itself a cost: the practice cannot compare without two sales calls. Third, the one-platform figure includes AI summaries, transcription and unlimited extensions, which the separate stacks either lack or sell as upgrades.

How many BAAs does each setup need?

One platform needs one Business Associate Agreement. Separate vendors need one for each vendor that handles PHI, which in the stacks above means two or three.

The rule comes from the HIPAA Privacy Rule. Under 45 CFR 164.502(e)(1), a covered entity may disclose PHI to a business associate, or let it create, receive, maintain or transmit PHI on its behalf, only with satisfactory assurance. That assurance is that the business associate will appropriately safeguard the information. Under 164.502(e)(2), that assurance must be documented in a written contract that meets 45 CFR 164.504(e). Section 164.504(e)(2) lists what the contract must say. The terms cover permitted uses and disclosures, safeguards, breach reporting, flow-down to subcontractors, access and amendment rights, availability of records to HHS, and return or destruction of PHI at termination.

A phone system that stores voicemail and recordings, a texting app that stores patient messages and a fax service that stores documents each maintain PHI on the practice’s behalf. HHS’s business associate guidance describes vendors that store or process PHI as business associates and excludes only pure conduits that transmit without storing. Three vendors therefore mean three agreements to negotiate, three sets of terms to reconcile and three breach-notification clauses to track. The BAA guide walks through which channels trigger the requirement.

Fewer agreements is not only convenience. Under 164.504(e)(1)(ii), a covered entity that knows of a pattern of activity by a business associate that breaches the contract must take reasonable steps to cure it or terminate the arrangement. Monitoring one vendor is easier than monitoring three.

Law firms and financial firms are not HIPAA covered entities and do not sign BAAs for their own clients’ data. They do have confidentiality and recordkeeping duties, and each extra vendor is one more party holding privileged or regulated communications. The law and financial vertical guides cover those frames.

What costs do not show on either invoice?

Three costs are real and absent from every quote.

Staff time. A front desk that checks three systems for one patient spends minutes per interaction reconciling them. A text that arrives in one app while the call log sits in another is the usual source of a missed follow-up. One timeline removes the reconciliation step.

Gaps between systems. When texts live outside the phone system, access controls and audit logs do not reach them. The practice may hold three audit logs in three formats, or two logs and a personal phone with none. The HIPAA Security Rule’s audit-control standard in 45 CFR 164.312(b) applies to all of it.

Renewal management. Three vendors mean three renewal dates and three notice windows. Missing one on an annual contract costs a year. Month-to-month plans have no such date.

None of these are priced in the table above. All of them favor fewer vendors.

How ZentryVoice handles this

ZentryVoice is a unified communications platform for medical, dental, legal and financial practices: calls, encrypted two-way texting, eFax, transcribed voicemail and AI call summaries on one number, for $20 per user per month, month-to-month, with a BAA countersigned at signup.

• One bill: seats at $20 per user per month; texting and eFax at $15 per practice per month each, charged per practice rather than per seat; optional desk phones at $119 one-time; optional support plans from $15 per month.
• One agreement: the Business Associate Agreement is presented for e-signature during signup and countersigned by ZentryVoice before texting or fax can be enabled on a medical or dental account. It covers calls, voicemail, texting and fax on the same account. Law firms receive a Confidentiality and Privilege Addendum and financial firms a Recordkeeping and Supervision Addendum.
• One record: every call, text, fax and voicemail is written to one timeline per patient or client and one immutable audit log.
• No exit cost: month-to-month, 30-day trial, no early-termination fee, no charge to port numbers in or out.

The pricing page computes the 3-year total for any seat count. The hidden costs guide lists the fees that appear on separate vendors’ invoices, and the vertical guides cover the compliance frame for each kind of practice.
