Every restaurant knows the Friday problem. The book is full at noon, and at eight there are three empty tables. Phoning every booking is slow, and most calls go to voicemail.
The number they already know
Guests answer messages from a number they recognise. A confirmation from your own WhatsApp number, with Confirm and Cancel replies, takes a guest a second to answer. The floor updates as the replies arrive.
A cancelled table at four o'clock can still be sold. A no-show at eight cannot.
Back on sale
The value is not only in the guests who confirm. It is in the cancellations that arrive early enough to matter, and the waitlist that hears about them first.
