$99/mo
CallSprint · flat-rate

Unlimited missed-call text-backs. 24/7 AI coverage. No minute or per-call caps.

$250–$400/mo
Virtual receptionist (Ruby, Smith.ai, etc.)

Base fee plus per-minute billing — every spike drives your bill higher.

$3,200+/mo
In-house receptionist

Salary plus benefits. Limited hours — after-hours and weekend coverage is rare.

One job captured pays for months.
If CallSprint books just one additional service call per month, the $99 plan pays for itself. Most businesses capture 3–5 missed opportunities per week — even one of those covers the whole year.

Common questions

No per-call or per-minute caps — ever. Your flat $99/month covers unlimited missed-call text-backs and AI conversations, so a freeze week or summer AC rush doesn't drive your bill up.
Yes — 24/7/365. CallSprint texts back missed callers within 5 seconds regardless of business hours, weekends, or holidays, so a burst pipe at midnight gets the same response as a Tuesday morning inquiry.
The AI absorbs overflow during seasonal spikes — freeze season, summer AC rush, summer storm surges. Every caller gets a text-back; nobody ever hits a busy signal, no matter how busy the phones get.
No long-term contracts. Monthly plans are month-to-month — cancel anytime with 30 days notice. Annual plans are billed once per year at the discounted $950/yr rate. Setup fees are non-refundable after work begins.
Setup is complete in roughly 24 hours after we receive your call-forwarding details and your business-specific information. The $250 setup fee covers AI script writing, calendar integration, and quality-assurance testing. You'll be live before the first monthly invoice hits.
Uptime is monitored 24/7. If there's a system outage, you receive immediate notification and a service credit proportional to the downtime. Since missed-call text-back runs on independent infrastructure, a single incident doesn't take coverage down.
Yes. Switch from monthly to annual anytime — we'll prorate the difference. Annual subscribers moving back to monthly take effect at the start of the next billing cycle.
No hardware changes needed. CallSprint works with your existing phone number via call forwarding. We handle all configuration — you keep your current carrier and number.
The $250 setup fee covers the initial configuration: AI script writing tailored to your business, calendar integration, team training, and quality-assurance testing. It's a one-time charge, separate from your $99/month plan. You'll pay the setup fee before work begins.
Any call that rings without being answered by a human — including calls that go to voicemail. CallSprint texts the caller within 5 seconds of the missed call, giving you the opportunity to respond before your competitor does.
