TL;DR: Measuring the ROI of an AI voice receptionist comes down to three numbers: missed calls recovered, staff hours freed, and new bookings captured. For a typical Irish SME receiving 40 calls a day, switching to an AI receptionist can save €18,000–€35,000 annually while increasing bookings by 15–30%. Here's exactly how to calculate it for your business.
Why Do Irish Businesses Struggle to Measure AI Receptionist ROI?
Most Irish business owners know they're losing money to missed calls. BIA/Kelsey research shows 85% of callers who can't reach a business won't call back — they'll ring the next result on Google instead.
But when it comes to justifying the cost of an AI voice receptionist, the maths feels murky. You're comparing a visible monthly subscription against invisible losses: calls that went to voicemail, customers who hung up, after-hours enquiries that vanished.
The good news? Measuring ROI from an AI voice receptionist is more straightforward than you'd think. It boils down to quantifying three things you're already losing.
What Are the Three Pillars of AI Receptionist ROI?
1. Recovered Revenue from Missed Calls
This is the biggest number — and the one most Irish businesses underestimate.
How to calculate it:
| Metric | How to Find It | Example (Dublin Dental Practice) | |--------|---------------|----------------------------------| | Average missed calls per week | Check your phone system logs or Google Business call reports | 35 missed calls/week | | % of missed calls that were potential bookings | Industry average: 25–40% | 30% = 10.5 potential bookings | | Average booking value | Your average transaction/appointment | €120 | | Weekly lost revenue | Missed calls × booking % × value | €1,260/week | | Annual lost revenue | Weekly × 50 weeks | €63,000/year |
An AI voice receptionist answers 100% of calls, 24/7. Even conservatively recovering 30% of previously missed opportunities, that's €18,900 annually in recaptured revenue.
A Cork-based restaurant using AI phone answering reported recovering 42 additional reservations per month within the first 90 days — worth approximately €3,360/month in covers.
2. Staff Cost Savings
Irish employers know the cost of a receptionist. According to Indeed Ireland, the average receptionist salary in Dublin is €28,000–€32,000 before employer PRSI (10.75%), sick leave, and holiday cover.
Full cost of a human receptionist in Ireland:
| Cost Component | Annual Amount | |----------------|--------------| | Base salary | €30,000 | | Employer PRSI (10.75%) | €3,225 | | Holiday cover (4 weeks) | €2,308 | | Sick leave (avg 5 days) | €577 | | Training & onboarding | €1,000 | | Total | €37,110 |
An AI voice receptionist costs €99–€499/month depending on call volume — that's €1,188–€5,988/year.
Net saving: €31,122–€35,922 per year.
Now, most businesses won't eliminate their receptionist entirely. But the AI handles overflow, after-hours, and peak times — meaning you might go from two receptionists to one, or free your existing receptionist for higher-value work like patient care or in-person customer service.
3. Extended Availability Revenue
Irish consumers expect to book outside business hours. According to a 2025 Zendesk study, 64% of customers expect real-time responses regardless of the time of day.
For a business that closes at 6 PM, that's 14 hours of unanswered calls every weekday, plus full weekends. An AI receptionist captures every single one.
After-hours booking calculation:
| Metric | Value | |--------|-------| | After-hours calls (typical Irish SME) | 8–15/day | | Conversion rate with AI answering | 20–35% | | Average booking value | €100 | | Additional monthly revenue | €3,200–€10,500 |
A Galway physiotherapy clinic reported that 22% of their total bookings now come from after-hours AI-handled calls — revenue that simply didn't exist before.
How Do You Calculate Your Specific ROI?
Here's a simple framework any Irish business can use:
Step 1: Baseline your current missed calls
- Check your phone provider's missed call report for the last 30 days
- If you use Google Business Profile, check the "calls" tab for unanswered calls
- No data? Use this benchmark: Irish SMEs miss 20–40% of incoming calls (SalesForce, 2025)
Step 2: Assign a value per call
- Total revenue last 12 months ÷ total inbound calls = revenue per call
- Example: €400,000 revenue ÷ 8,000 calls = €50 per call
Step 3: Calculate the gap `` Monthly missed calls × Revenue per call × Recovery rate (30%) = Monthly recovered revenue ``
Step 4: Add cost savings `` Current phone handling costs - AI receptionist cost = Monthly savings ``
Step 5: Combine `` (Monthly recovered revenue + Monthly savings) ÷ AI receptionist monthly cost = ROI multiple ``
Most Irish businesses see a 5x–15x return within the first 90 days.
What KPIs Should You Track After Installing an AI Receptionist?
Once your AI voice receptionist is live, track these metrics monthly:
- Call answer rate — Should jump from 60–80% to 99%+
- After-hours bookings — New revenue that didn't exist before
- Average response time — AI answers in <1 second vs. 15–30 seconds for humans
- Booking conversion rate — Calls that result in appointments/orders
- Staff hours freed — Track what your team does with reclaimed time
- Customer satisfaction — Ask callers to rate their experience
- Cost per call handled — Total AI cost ÷ calls answered
Pro tip: Set up a simple spreadsheet tracking these weekly for the first 3 months. The ROI story writes itself.
How Does AI Receptionist ROI Compare Across Irish Industries?
Not every business sees the same returns. Here's how the numbers typically stack up:
| Industry | Avg. Missed Calls/Week | Value per Missed Call | Monthly ROI Potential | |----------|----------------------|----------------------|---------------------| | Dental practices | 30–50 | €80–€150 | €5,000–€12,000 | | Restaurants (Dublin/Cork) | 40–80 | €25–€60 | €3,000–€8,000 | | Legal firms | 15–25 | €200–€500 | €4,000–€15,000 | | Trades (plumbers, electricians) | 20–40 | €100–€300 | €4,000–€10,000 | | Estate agents | 25–45 | €50–€150 | €3,000–€9,000 | | Medical/physio clinics | 30–60 | €60–€120 | €4,000–€10,000 |
Dental practices and legal firms typically see the fastest ROI because their per-appointment value is high and their missed call rates are among the worst — receptionists are often busy with in-office patients.

What's the Break-Even Point for an AI Voice Receptionist?
For most Irish businesses, the break-even happens within the first week.
Here's why: if your AI receptionist costs €199/month and captures just 2 additional bookings worth €100+ each that you'd have otherwise missed, you've already covered the cost. Everything after that is pure profit.
Compare that to hiring a second receptionist at €2,500+/month, or an answering service at €500–€1,500/month that still can't book appointments or access your calendar.

Frequently Asked Questions
How quickly will I see ROI from an AI voice receptionist?
Most Irish businesses see positive ROI within the first 5–7 days. The AI immediately starts answering calls you'd otherwise miss, and with average booking values of €80–€150, it only takes 1–2 recovered bookings to cover the monthly cost.
What if my business only gets 10–20 calls a day?
Even low-volume businesses benefit significantly. If you miss just 3–5 calls per day and each is worth €50+, that's €750–€1,250/month in lost revenue. An AI receptionist costing €99–€199/month delivers a 4x–12x return even at low volumes.
Can I measure ROI if I don't have historical missed call data?
Yes. Start by installing the AI receptionist and tracking from day one. Within 30 days, you'll have a clear picture of total calls answered, after-hours calls captured, and bookings made. Compare this against your previous month's booking numbers for a before/after analysis.
How does AI receptionist ROI compare to a traditional answering service?
Traditional answering services in Ireland cost €300–€1,500/month and can only take messages — they can't book appointments, answer specific questions, or access your calendar. An AI receptionist does all of this for €99–€499/month, making it 3–5x more cost-effective with better conversion rates.
Should I replace my human receptionist entirely?
For most businesses, no. The best approach is using AI to handle overflow, after-hours, and peak times while your human receptionist focuses on in-person customer experience. This hybrid model typically delivers the highest ROI because it eliminates missed calls without losing the personal touch for walk-in customers.
