Free tools for small businesses

Simple calculators that run in your browser, with no sign-up and no default benchmarks. Each one explains its method, and the industry pages start from a clearly labelled example you replace with your own numbers.

Missed-call cost estimator

Free estimator: enter your own calls, missed share, conversion rate and (optionally) customer value to see what unanswered calls put at risk each month.

Receptionist coverage calculator

It depends on call length and how many busy callers you accept. Work out calls per hour and receptionists needed with this free Erlang calculator.

Lead response time checker

Within the hour at most, and minutes is better. Paste your own lead times to check your median response, in clock time and in business hours.

WhatsApp and DLT template checker

Body 1,024, header 60, footer 60, button 25 characters. Check a WhatsApp template or a DLT SMS template against the published limits, free.
