How to reduce restaurant no-shows

That’s good news, because forgetting and awkwardness are things you can design around. Here’s what to do, roughly in the order it’ll pay you back.

1. Ask guests to confirm, at the right time

A confirmation ask does two jobs. It reminds the people who’d forgotten, and it gives the ones whose plans have changed an easy way to tell you.

When resOS looked at bookings at the same restaurants with and without a delivered text reminder, the bookings with one had a 16% lower recorded no-show rate (resOS No-Show Index, Aug 2026). resOS is careful to call that an association rather than proof, but it points the same way as what guests say. In Zonal and CGA’s 2021 research, more than a third of people who’d forgotten a booking said a reminder would have got them there (Zonal/CGA, Sept 2021).

When to send it

• 24–48 hours before works for most bookings. It’s close enough that plans are firm, and early enough to refill the table.
• On the day, a short nudge suits lunch, early tables and walk-in-heavy venues, where bookings are often made the same week.
• Further ahead suits big parties, set menus and special dates, which are worth a first check a few days out and a second the day before.

Guests aren’t of one mind. In the 2021 research, 38% preferred a reminder a few days ahead and 28% on the day itself. So one well-timed message beats three badly timed ones.

Ask for a reply

“Reply YES to confirm or NO to cancel” turns a reminder into information you can act on. A NO at 3pm is a table you can sell at 8pm. Silence on a booking that usually replies is worth a phone call.

2. Make cancelling easier than not turning up

If 15% of no-shows happen because cancelling felt like effort, every step you remove helps. Give guests a reply-to-cancel option in the text, a link to change or cancel, and a phone number that someone actually answers at service time.

Offer more than one route. In 2021, 58% of guests preferred to cancel digitally and 39% still preferred to phone (Zonal/CGA).

Make it guilt-free, too. “No problem, thanks for letting us know” costs nothing. People who feel told off for cancelling are the ones who don’t bother next time.

3. Keep a waitlist, and use it fast

A cancellation is only worth something if you can refill the table. Keep a waitlist for busy services, with names, party sizes and mobile numbers, and decide in advance who on the team texts the next person when a NO comes in. A table released at 5pm for a 7.30 sitting is very fillable on a Friday. One released at 7.25 usually isn’t.

4. Put deposits or card guarantees where the risk is

Deposits work, but they also put some people off booking at all. In takepayments’ survey, “44% are put off making a reservation when a restaurant asks for card details”. So use them where an empty table really hurts:

• Large parties, where one no-show empties a section
• Peak nights and dates like Valentine’s, Mother’s Day and the December weekends
• Set or tasting menus, where you’ve bought and prepped for each cover

It’s worth knowing that big groups don’t necessarily no-show more often. In resOS’s 2026 data, parties of ten or more had a lower recorded rate (1.15%) than tables of one or two (2.63%). You protect them because each one costs more when it goes wrong. Our guide to deposits covers the trade-offs.

5. Write a policy guests can actually read

A short, plain policy shown at the time of booking does more than a long one buried in your terms. Say how much notice you need, what happens if someone doesn’t turn up, and what you’ll do if you have to cancel. Our no-show policy template gives you wording to start from.

6. Track it, so you know what’s working

You can’t improve a number you don’t record. Mark every no-show in your booking system, even when it’s busy, and look each month at:

• The no-show rate by day and by service
• Party size and how far ahead people booked
• How many guests replied to your confirmation ask, and how many said NO in time for you to rebook

Recorded rates usually run lower than real ones, because unmarked no-shows vanish from the count. resOS says as much about its own figures. The habit of marking them is worth more than any single tactic above.

Where to start

If you do one thing this week, start asking guests to confirm 24–48 hours ahead, with a one-word reply and an easy way to cancel. Then add a waitlist for your busiest nights, and deposits only where the numbers justify them.
