Many customers do not call when it is convenient for the business. They call when it is convenient for them.
That might be after work, during lunch, in the evening, on a weekend, or while comparing businesses online.
If your business is closed, those calls often disappear.
The customer may not leave a voicemail. They may not email. They may simply continue searching.
After-hours calls are easy to underestimate because they are invisible. You only see the customers who reach you. You do not see the ones who tried and moved on.
An AI receptionist can answer after hours, explain opening times, collect the customer's request and send a summary for the next working day.
