Inputs

Worked examples

Local Home Services / HVAC (150 calls/mo, $850 job ticket)

A plumbing/HVAC company misses 22% of inbound calls (33 calls). 35% are new leads closing at 30%. Result: $2,945/mo Leaked ($1,473 Recoverable with SMS).

Missed calls = 33. Lost prospective jobs = 33 × 35% × 30% = ~3.46 jobs. 3.46 × $850 = $2,945 lost monthly.

High-Ticket Dental / Orthodontics Practice (300 calls/mo, $3,200 avg case)

A dental clinic misses 15% of calls (45 calls). 40% are new patients closing at 25%. Result: $14,400/mo Leaked ($8,640 Recoverable).

Missed calls = 45. Lost cases = 45 × 40% × 25% = 4.5 cases. 4.5 × $3,200 = $14,400 lost per month.

Frequently asked questions

What percentage of phone callers leave a voicemail when not answered?

Industry benchmarks from Invoca and Marchex show that over 80% to 85% of first-time callers will NOT leave a voicemail. Instead, they immediately click the next competitor in Google search results.

How does automated missed-call text-back work?

When a call is missed, the system immediately sends a personalized SMS within 5 seconds (e.g. "Hi, sorry we missed your call! How can we help you right now?"). This initiates an instant two-way text conversation and retains the lead before they call a competitor.

Is it worth investing in phone automation if we only miss 15% of calls?

Yes. As shown above, even missing 15-20% of calls can leak tens of thousands of dollars annually for service, healthcare, trade, legal, and local businesses where customer lifetime values exceed several hundred dollars.

How do you calculate lost revenue from missed calls?

Formula: Lost Revenue = Total Inbound Calls × Missed Call % × New Lead % × Conversion Close Rate % × Average Customer Value. For example, 200 calls × 20% missed (40 calls) × 30% new leads (12 leads) × 25% close rate (3 jobs) × $800 avg ticket = $2,400 monthly loss.

What is the fastest way to recover missed inbound leads?

Instant automated text-back triggered within 15 seconds has been shown to recover up to 50% of otherwise lost callers, shifting the interaction from a lost phone call to an active text chat.
