If you run a dental practice or med spa and you're tired of voicemail eating your appointments, three names keep showing up in the research rabbit hole: Posh, Ruby, and Apex Tools AI. Posh and Ruby are the established human-staffed virtual receptionist services. Apex Tools AI is the newer, bilingual, AI-first option built specifically for dental and aesthetic medicine.
This is the honest comparison nobody else will write for you — partly because we are Apex, and partly because we think the choice actually depends on what kind of practice you run. We'll show you where Posh wins, where Ruby wins, where Apex wins, and where none of the three is the right answer.
The 30-second comparison
| Feature | Posh | Ruby | Apex Tools AI | |---|---|---|---| | Starting monthly cost | $65/mo + $2.25–$2.30/min | $129/mo (limited minutes) | $400/mo flat | | Realistic monthly cost (300–500 min) | $740–$1,215/mo | $235–$640/mo | $400/mo flat | | Setup time | 1–2 weeks | 1–2 weeks | 5 business days | | Bilingual (EN/ES) | Add-on, limited | Bilingual answering optional | Built in, no extra cost | | Calendar booking | Manual, agent-assisted | Manual, agent-assisted | Direct integration | | Practice-size fit | Solo to mid-size | Solo to mid-size | Solo to 10-doctor | | Support model | Human agent pool | Human agent pool | Founder-led + AI | | 24/7 coverage | Yes | Yes | Yes | | Per-minute risk | High (overage) | High (no rollover) | None (flat) |
Now the long version.
What Posh actually is
Posh is a US-based virtual receptionist service that has been around since 2009. Their model is human receptionists who answer the phone under your practice's name, take messages, transfer calls, and handle light scheduling. They publish their pricing openly, which is rare in this category and worth credit.
Posh charges a monthly base plus a per-minute rate. Their entry "Chic" plan is $65/mo plus $2.30 per receptionist minute. Their top published tier runs $1,850/mo and includes 1,000 minutes with $1.85/min overage. Per-minute rates across tiers sit between $1.85 and $2.30.
Where Posh genuinely wins:
- Live human voice on every call, which still matters in some patient interactions, especially complaint calls or sensitive consults.
- A clean, well-rated client portal for reviewing call logs and messages.
- Light scheduling and basic intake at the lower tiers without forcing you into an enterprise contract.
- Transparent published pricing.
Where Posh struggles for dental and med spa specifically:
- Per-minute billing punishes the practice for the very calls you want answered. A 4-minute new-patient call costs roughly $9 in receptionist time. Do 200 of those a month and you're at $1,800 before base fees.
- Bilingual Spanish coverage is not a default. Posh can route Spanish calls but it isn't the same always-on bilingual experience a Spanish-preference caller gets from a dedicated bilingual line.
- Posh receptionists are not trained on your PMS workflow — Dentrix, Open Dental, NexHealth integrations are not native. Scheduling happens by message-relay or via a shared calendar, not direct write-to-PMS.
- The team is generalist. A Posh agent might be answering for a law firm at 9:14 and a dental practice at 9:15. They are good at being polite and accurate; they are not specialists in implant consults or filler treatment questions.
What Ruby actually is
Ruby (formerly Ruby Receptionists) is the other established US-based virtual receptionist player, founded in 2003 and one of the most-reviewed brands in this category. They run a similar model to Posh — live human receptionists, monthly plans, friendly brand, strong Trustpilot reputation.
Ruby's published plans range roughly from $129/mo at the low end to $1,640–$1,725/mo at the top. The widely-discussed plans are $235/mo for 50 minutes up to $999/mo or more for larger blocks. Bilingual answering is available as an optional feature in all tiers.
Where Ruby genuinely wins:
- One of the most consistent live-agent experiences in the industry, with high reviewer scores for tone and professionalism.
- Bilingual answering is offered across plans rather than only at enterprise tiers, which is better than most human services.
- Solid mobile app for reviewing messages, sending instructions, and updating status.
- Strong choice for law firms and professional services where the human voice is a core part of brand perception.
Where Ruby struggles for dental and med spa specifically:
- Minutes do not roll over. Pay for 200 and use 150, the other 50 vanish. That makes budgeting hard for practices with seasonal swings.
- Like Posh, Ruby is a generalist. Their agents are not embedded in your PMS, and they are not building dental-specific scripts day in and day out.
- Bilingual is optional, not the default. A Spanish-preference caller may still hit an English-first interaction depending on routing.
- The per-minute math becomes brutal as call volume grows. A practice doing 800–1,200 minutes a month can easily push past $1,500/mo with Ruby — without any direct PMS booking.
What Apex Tools AI actually is
Apex Tools AI is a bilingual AI phone receptionist built specifically for dental practices and med spas. The voice agent answers in English or Spanish based on what the caller speaks, books directly into Dentrix, Open Dental, or NexHealth via the integrations we maintain, and runs 24/7. The phone plan is $400/mo flat with no per-minute pricing. A bundle that adds web chat is $450/mo. Chat-only is $100/mo. Setup is 5 business days and there's a 30-day money-back guarantee.
Where Apex genuinely wins:
- Bilingual EN/ES is built in. The agent detects the caller's language and switches automatically. No add-on fee, no "Spanish hours only" carve-out. For practices in Florida, Texas, California, New York, and most major metros, this is the single biggest unmet need we hear about every week.
- Dental and med spa specialization. The scripts, the consult-vs-cleaning routing, the filler-vs-Botox triage questions, the implant-consult capture playbook — all of that is built around two verticals, not eighteen.
- Flat $400/mo phone pricing means the marginal cost of an answered call is zero. The economic incentive is finally aligned: more calls answered is better for the practice and doesn't punish the budget.
- 5-day setup vs the 1–2 weeks of human-staffed services and the 2–6 weeks typical of enterprise vendors like Dialpad or Five9.
- Founder-led service. When something needs to change in your prompt or your routing, you're not opening a ticket in a faceless portal — you're talking to the team that built it.
Where Apex is honestly weaker than Posh and Ruby:
- We're newer. Posh has been doing this since 2009 and Ruby since 2003. We started focusing on dental and med spa specifically in 2024. That's a credibility gap we earn back with case studies and the 30-day guarantee, but it's real.
- Posh and Ruby have larger live-agent pools. If you have a strong philosophical preference for a human voice on every call, an AI receptionist — even a good one — won't change your mind, and that's fair.
- We are not the right fit for >10-doctor multi-location practices with bespoke routing requirements and dedicated IT teams who want a unified-communications platform. For those, Dialpad or Five9 are better fits. We're built for 1–10 doctor practices and single-to-small-chain med spas.
- We have fewer enterprise integrations than Dialpad. If your stack runs through Salesforce Service Cloud or a complex IVR tree feeding multiple departments, we are not the right answer.
Real cost math for a typical practice
Let's compare what each option actually costs a 2-doctor dental practice in Miami, FL doing roughly 1,000 inbound minutes a month with ~30% Spanish-preference callers.
Posh: A tier with about 1,000 minutes is in the $1,850/mo range based on their published pricing. Bilingual is not native; you'd need to factor in some calls being relayed to a Spanish-capable agent, which may or may not be seamless. Effective cost: $1,850/mo + the friction tax of bilingual routing.
Ruby: 1,000 minutes lands you in the upper plans, in the $1,640–$1,725/mo range. Bilingual answering is available as an opt-in feature. Effective cost: $1,640–$1,725/mo, plus the bilingual feature.
Apex Tools AI: $400/mo flat for the phone plan, $450/mo if you want web chat bundled in. Bilingual is included. Direct calendar write to Dentrix or Open Dental is included. Effective cost: $400/mo.
The savings is real, but it's not the only thing that matters. Posh and Ruby are giving you human voices. Apex is giving you a bilingual specialist that books appointments directly into your PMS and never sleeps. Those are different products. The question is which one matches your practice.
How to pick in 60 seconds
Choose Posh if you primarily want a polished live-human voice for a small practice, you don't care much about bilingual coverage, your call volume is low and predictable, and transparent per-minute pricing fits your budget mindset.
Choose Ruby if you want the most-reviewed human service in the category, you value strong brand consistency, bilingual answering as an add-on is acceptable, and your call volume is steady enough that you won't lose minutes month to month.
Choose Apex Tools AI if you run a dental practice or med spa, you have meaningful Spanish-preference patient volume, you want direct PMS booking instead of message relay, you'd rather pay $400 flat than $1,500+ variable, and you can live with a younger company that backs the work with a 30-day money-back guarantee.
Choose none of the three if you're a 15-doctor DSO with a dedicated IT team, complex multi-tenant routing, and an enterprise UCaaS strategy. Talk to Dialpad or Five9.
What we'd tell our own family
If a cousin opened a 3-operatory dental practice in Hialeah and asked us where to start, we'd say try Apex for 30 days, take advantage of the guarantee, and see whether your missed-call rate drops and your Spanish-language conversions go up. If they do, you've solved the problem for $400/mo and you can stop reading comparison posts. If they don't, you've spent less than one month of Ruby's mid-tier plan to find out, and you can move on to a human service with real data in hand.
That's not a sales pitch. That's how the math works.
