What turned-away bookings really cost, and how to measure it
Every restaurant, hotel and salon turns customers away. You're full on Saturday at 8, so the phone call ends with "sorry", the email gets a polite no, or the website just shows nothing free. The customer goes elsewhere, and there's no record it ever happened. It's the one cost that never shows up in your accounts.
- Turned-away demand is invisible unless you write it down.
- Four weeks of simple records show you when, how often and how many.
- Then you can do something about it: another sitting, more staff on the right nights, or offering the next free time.
Why it's invisible
Your till shows the customers you served. Your booking system shows the bookings you took. Neither shows the people you said no to. So the busiest nights look like your best nights, when they may also be the nights you lost the most.
How to measure it in four weeks
- Write down every no. Phone, email, website, walk-in. Note the date, the time they wanted, and how many people.
- Keep it going for four weeks. That's enough to see a pattern without it becoming a chore.
- Group it by day and time. You'll usually find a few slots doing most of the damage.
- Put a value on it with the simple sum below.
The sum
Demand turned away per week = people turned away × your average spend per head.
Not everyone you turn away is lost for good. Some would happily come at another time. So the part worth chasing is the share you could have seated if you'd offered something else.
| Worked example (illustrative numbers) | Figure |
|---|---|
| People turned away in a typical week | 30 |
| Average spend per head | £35 |
| Demand turned away per week (30 × £35) | £1,050 |
| Share you could seat at another time (say one in three) | £350 a week |
| Over a year (× 52) | £18,200 |
These are example numbers to show the sum, not an average. Use your own: four weeks of records will give you a far better figure than any guess.
What to do with what you find
| If you see… | Try… |
|---|---|
| The same few slots full every week | An earlier or later sitting, or shorter table times at peak |
| Big groups turned away | Pre-booked set menus, or a private area on quieter nights |
| People asking when you're closed | Answering enquiries out of hours, so they book for another day instead of going elsewhere |
| Busy nights short of staff | Rota the busy slots first, from the pattern, not from memory |
Doing it without the clipboard
Writing down every no works, but it relies on busy staff remembering. Marina, Lagoona's bookings team member, takes booking enquiries around the clock and checks the real diary before it answers. Every time a request can't be fitted in, it records the day, the time and the party size, and its dashboard, Customers you turned away, shows the pattern for you, week by week.
