Phone Assistant for Medical Practices: What Does It Really Cost?
Honest cost comparison across four options — additional MFA, external service, IVR, AI phone assistant — including break-even math and hidden line items.

Phone-load reduction costs in a medical practice vary widely: an additional MFA position runs around €60,000 fully-loaded per year, external answering services €1,500–4,000 per month, AI phone assistants typically €100–400 per month. The most economical option depends on call volume, required feature scope, and whether outbound campaigns need to be covered.
- 01An additional MFA position dedicated to phone work costs roughly €60,000 per year all-in, including social charges and turnover overhead.
- 02External answering services run €1.50–4.00 per call — easy to scale, but no structured PMS handoff.
- 03Classic IVR menus reduce real-time stress but don't dissolve the processing queue — abandonment rates of 20–35 % are documented.
- 04AI phone assistants typically cost €100–400 per month and break even with as little as 10 % MFA-time savings.
- 05Hidden line items: implementation fees, minimum contract terms, surcharges for outbound and multilingual support.
Four options, four cost profiles
A practice that wants to reduce phone load has essentially four options: hire an additional MFA, retain an external answering service, install an extended IVR system, or deploy an AI phone assistant. Each carries its own cost profile — and the cheapest-on-paper option is rarely the most economical in practice. This article runs the numbers honestly for all four, with assumptions you can transfer to your own practice.
As a baseline we model a mid-sized German general practice: two physicians, four MFAs, around 80 inbound calls per workday. Roughly 60 % of those are routine intents that can be handled without medical judgment — cancellations, prescription refills, hours-and-directions questions. That's where all four options compete.
The real cost of an additional MFA on the phone
Hiring another MFA is the reflex response to rising call volume. The actual cost is much higher than the gross salary suggests. A full-time MFA in pay grade 5 costs the employer, in 2026, roughly €45,000 to €55,000 per year all-in (social charges, paid leave, sick-pay continuation), depending on region and experience.
On top of that come the softer costs: onboarding (three to six months until full productivity), recruitment (job ads and hiring process often in the four-digit range), workplace equipment, and turnover. An average MFA position changes employer every three to five years — every change triggers the full onboarding cost again.
Realistically, an additional MFA position dedicated to phone routine lands at a fully-loaded cost of around €60,000 per year — and competes in a tight labor market against applicants who'd rather spend their time on more complex patient work.
External answering service: pros and cons
External answering services — secretarial outfits that handle calls for multiple practices — typically bill per minute or per call. Common pricing sits between €1.50 and €4.00 per call, depending on time-of-day and the service's specialization. At 80 calls per workday with 60 % forwarded, that puts monthly cost in the €1,500–€4,000 range.
The upside: no personnel responsibility, fast activation, scales on demand. The downside: the service doesn't know your practice in detail, can't do structured PMS handoff, and usually delivers intents as a manually typed email or PDF. When callbacks are needed, MFAs often call back because the data needed to handle the request is incomplete.
External services make sense where the core requirement is availability, not structured handoff.
IVR systems: why the cheap-looking option gets expensive
An extended IVR ("press 1 for appointments, 2 for prescriptions...") costs little to acquire — often just a one-time configuration fee plus maintenance. The real cost is hidden: patients abandon calls when they can't navigate the menu. Studies from the German practice context show abandonment rates of 20–35 % on multi-level IVR menus.
And: an IVR doesn't replace intent classification. Patients end up in a menu item that records a voicemail — and your MFA listens to that later and manually types it into the PMS. The phone load shifts from real-time conversation into a deferred processing queue; it's not eliminated.
AI phone assistant: cost structure and break-even math
AI phone assistants are usually billed as a monthly subscription, tiered by call volume and feature scope. For reference: Vitas, per telefonassistent.de/preise, starts with a FLEX tier from €40/month and a BASIC tier at €98/month for 500 conversations; multilingual conversations are an additional Pro package at €99/year. PLUS with 1,500 conversations sits at €245/month.
Sinalis prices to practice size and call volume, with outbound recall and DMP calls plus the patient-keyed timeline included in the base scope. For the practice modeled above (80 calls/workday is roughly 1,700 conversations/month), the order of magnitude is typically in the low-to-mid three-digit euro range per month, depending on feature scope.
Break-even: even an AI assistant at €300/month is €3,600/year — against ~€60,000 for an additional MFA. If the assistant saves only 10 % of MFA phone time, it already pays for itself.
Hidden costs and implementation effort
In any comparison, watch four often-overlooked cost items.
Implementation fees. Some vendors charge a one-time configuration fee in the four-digit range. Others bake it into the running subscription.
Minimum contract term. 12-month contracts are standard; some vendors insist on 24 months. This matters if you're not sure the solution fits.
Premium-feature surcharges. Multilingual, outbound, additional conversation branches — often add-ons. Always compare tiers against the exact feature list you actually need.
Internal MFA onboarding. Even the best system needs a few hours of team familiarization. Budget two to four weeks of adjustment time, during which reporting won't be 100 % representative.
Cost per call, side by side
| Option | Cost / month | Cost / call | Structured handoff |
|---|---|---|---|
| Additional MFA position | ~€5,000 | ~€2.90 | Yes (manual) |
| External answering service | €1,500–4,000 | €1.50–4.00 | No (email/PDF) |
| Extended IVR system | €50–150 | €0.05–0.15 | No |
| AI phone assistant | €100–400 | €0.10–0.40 | Yes (structured) |
When each option fits
For small to mid-sized practices with moderate call volume and an existing PMS integration, an AI phone assistant is usually the most economical option. An additional MFA makes sense if you have non-phone overflow work that justifies the position. External services suit temporary spikes; IVR menus work as a pre-classification layer, not as the main solution. For vendor selection, see the selection guide; for data protection, the GDPR guide.
