What stands out
1,451 sales calls a year go unanswered (31%)
After callbacks, about 544 jobs are lost, worth $354K in revenue and $177K in gross profit.
The larger share of the loss (52%) happens during business hours
Business hours: $183K lost at a 80% answer rate. After hours: $171K lost at 25%.
Reaching a 90% answer rate recovers about $240K a year
At $1,500 a month the fix returns 565% on gross profit; it breaks even after 10 extra answered sales calls a month.
Only 25% of missed callers are won back
Instant text-back on missed calls and a callback within 5 minutes typically recover more callers than a next-day callback.
Next actions
- Add overflow routing during peak hours (rollover to a second line, office staff, or an answering service) so no call rings out.
- Turn on instant text-back for every missed call and set a 5-minute callback standard.
- Track answer rate weekly in your phone system; every point of answer rate is worth about $11K a year.
Model assumptions & limitations
- Missed calls that are not recovered by callback are assumed lost to a competitor.
- Answered calls book at your stated close rate; missed callers who are recovered book at the same rate.
- The fix scenario assumes a 90% answer rate in all hours and that recovered calls book like today's answered calls.
- Repeat business and referrals from lost customers are not included, so the true loss is likely higher.
