Plain-math ROI · formula shown

How much revenue does a missed call cost you?

Three sliders, real math, no marketing inflation. Tell us your inputs — we'll show recovered revenue, payback time, and net annual benefit. The formula is below the calculator so you can sanity-check it yourself.

Your numbers

Missed calls per week

Calls that go to voicemail or no-answer. Median small service business is 10-30/week.

Average job value ($)

$800

Roofer: $3,000-$15,000. Realtor commission: $5,000-$30,000. Roofer inspection: $200. Pick the average.

Current answering service / receptionist cost ($/mo)

$300

Set to 0 if you don't have one. Smith.ai starts at $255/mo. Rosie ~$60-$100/mo. A part-time receptionist can be $1,500+/mo.

Your BizBot plan cost ($/mo)

$96

Defaults to $96/mo — SiteLine Pro + Receptionist, the self-serve plan that includes the 24/7 AI receptionist and all six modules. On the other verticals the platform bundle is contact-sales, so set this to the price we quoted you.

Estimated impact

Recovered revenue / month $— — missed calls × — capture × — close × $— job value

Net benefit (after plan cost) $—/mo Revenue − your plan cost − current answering service savings if you cancel it

Payback time — days Days from signup to break-even on your plan cost.

Annual net benefit $—/yr 12 × (recovered revenue − plan cost) + answering-service savings.

Formula (transparent + conservative)

recovered_revenue_monthly = missed_calls_per_week × 4.33 × 0.45 (Recall capture rate) × 0.30 (close rate on captured) × avg_job_value

net_benefit_monthly = recovered_revenue_monthly − plan_cost_monthly (your slider) + current_answering_service_cost (assumed cancelable on Orbit deploy)

payback_days = (plan_cost_monthly / net_benefit_monthly) × 30

annual_net = net_benefit_monthly × 12

What we deliberately don't claim

The 0.45 capture rate is our internal Recall reply-rate within 30 minutes (sample n > 30 days production). It's deliberately conservative — actual is closer to 0.55 in some verticals, but we'd rather under-promise.
The 0.30 close rate is industry-typical for SMS-engaged leads in trades + real estate. Higher in some verticals (medical, legal); lower in others (retail). Conservative default.
This calculator does not include brand value of customers feeling responded-to, review-rating lift from Stars module, after-hours coverage value, or owner time saved. The actual ROI is meaningfully higher than what's shown — but only the parts that are easy to measure are shown.
Your numbers will vary. If you want a specific projection for your business, email Steve and we'll do it together.

Pick your vertical. The brain is already wired.

The six-module brain ships inside a vertical plan, not as a separate line item. For contractors it's self-serve today — SiteLine Pro + Receptionist, $96/mo. On the other verticals the platform bundle is contact-sales; tell us your vertical and we'll quote it.
