Limits and what to check
Staffed hours equal hours per day × days per week, capped at 168. Coverage is staffed hours ÷ 168. Enquiries outside hours equal weekly enquiries × your outside-hours share, and monthly figures multiply weekly figures by 52 ÷ 12. The even-spread figure is a reference only.

Frequently asked questions
Using the tool
Q1What is the even-spread reference?
It shows the share of enquiries that would fall outside staffed hours if they arrived evenly across all 168 hours of the week. It is a comparison point, not a statistic about your business.
Q2How are uncovered hours counted?
Your staffed hours per day are multiplied by staffed days per week and subtracted from the 168 hours in a week.
Q3Does the coverage result predict missed enquiries?
No. It applies the outside-hours share you enter to your weekly enquiries. Use your own enquiry timestamps for the most realistic share.
Q4Is my coverage data kept?
No. The coverage calculation runs in your browser, does not use an AI model and keeps nothing.
