## FAQs

### How do I actually measure my current missed-call rate?

Pull 30 days of call logs from your phone provider. Count total inbound calls. Count how many rolled to voicemail or ended under 10 seconds (a hangup before you picked up counts as missed). Divide the second number by the first. That is your miss rate. If your VoIP provider does not expose this easily, forward your main line to a Google Voice number for a week and count there — Google Voice logs are clean.

### What if my close rate is lower than 40%?

Use your real number. 30% is common for competitive, price-shopped trades. 25% is common if you are a premium provider quoting against three competitors on every call. The formula still works — just plug in what is true for you. At a 25% close rate and 200 calls/mo, the HVAC shop's gain drops from $7,200 to $4,500. Payback is still under a day.

### How long until payback?

For a typical small service business with 150+ calls/mo and a $300+ ticket, payback is under 5 days on the Starter plan. We have not modeled a realistic business where payback exceeds one month. If your math says 6+ months, recheck your close rate — you probably understated it.

### What if I already hit a 10% missed-call rate?

Good — your baseline is already tight. The AI moves you from 10% to ~0%. The gain is smaller but still meaningful. 200 calls × 10% × 40% close × $450 = $3,600/mo recovered vs the {{starter_price}} plan. Payback is 1.7 days. The ROI case is strongest for shops with 20%+ miss rates, but it still clears for tight operators.

### Is the math different for low-ticket vs high-ticket businesses?

Yes. Low-ticket high-volume (nail salon, dog grooming) lives or dies on volume — a $50 ticket at 300 calls/mo and 20% miss and 60% close = $1,800/mo recovered. Still covers the Starter plan 9x over. High-ticket low-volume (roofing, commercial HVAC) lives on close-rate and ticket size — one recovered job can pay for the plan for three years. The formula does not care; it just takes your inputs and multiplies.

### What about LTV vs first-ticket?

Use LTV for businesses with strong retention: dental, chiropractic, home-service contracts, pool maintenance, pet grooming. Use first-ticket for one-off transactional work: emergency plumbing, storm-damage roofing, single-service HVAC. The difference is whether a new customer is likely to buy again. If your repeat rate is above 40%, LTV is the right number.

### How do I account for seasonal volume?

Calculate steady-state first — that is your baseline ROI. Then model your peak month separately. For landscaping, April volume is 4x normal and April miss rates climb because crews are deployed. Use April-specific inputs to size the surge. A seasonal business often books its entire year of RingDesk cost in a single peak month and runs the rest of the year in pure upside.

### Is there a downside?

Yes, two honest ones. First, AI receptionists do not handle true emotional de-escalation — if a grieving homeowner calls a crematorium, you want a human. Route those categories to a human callback queue rather than letting the AI handle them end-to-end. Second, misconfigured AI is worse than voicemail. If you set up RingDesk and never review the call transcripts for the first two weeks, you will miss tuning opportunities and the AI will mishandle edge cases. Budget two hours a week for the first month to review and refine.

### What if my business mostly gets spam and robocalls?

RingDesk filters obvious spam before it touches your pipeline — STIR/SHAKEN attestation, known bad-number lists, and pattern matching on the opening seconds. Your effective call volume for the ROI calc should be the post-filter number, not the raw carrier count. Most shops find 10–20% of 'missed calls' were garbage anyway.
