Quick calculators and generators built for service businesses. No signup required.
Most service businesses are losing more to missed and mishandled calls than they realize. These free tools help you put a number on it — what unanswered calls cost you, how much after-hours volume you are leaving on the table, and how to make your phone intake consistent. No account needed; use the one that fits the question you are trying to answer.

Open toolWhat each tool does
Missed-Call Revenue Calculator
Enter your call volume, how many calls you miss, your average customer value, and your close rate. It estimates the monthly and annual revenue walking out the door — and what recovering even a fraction of those calls is worth.
When to use it: Use it when you are deciding whether 24/7 answering is worth it, or to put a real dollar figure on missed calls for yourself or a partner.
Open toolAfter-Hours Coverage Checker
Map your open hours against when calls actually come in. It estimates how many calls land while you are closed, on a job, or asleep — and how many you could recover with around-the-clock coverage.
When to use it: Use it when nights and weekends feel like a black hole, or when you suspect competitors are picking up the calls you let ring out.
Open toolLegal Intake Script Generator
Pick your practice area and answer a few prompts. It generates a structured intake script — the qualifying questions, conflict checks, and next steps — that your front desk or AI receptionist can follow on every call.
When to use it: Use it when your intake is inconsistent call to call, or when you are setting up an answering flow and want a proven question set to start from.
