Cut Appointment No-Shows: Reminders and Deposits That Work

How much are no-shows actually costing my business?

Multiply your monthly no-shows by your average booking value, then by the share of those slots you fail to refill. That figure is your real loss. Most owners have never worked it out, so the problem stays vague and gets tolerated.

The formula: no-shows per month × average booking value × (1 − share of slots you refill). As an illustration, take 12 no-shows a month at 45 each, with a quarter of the slots refilled. That is 12 × 45 × 0.75 = 405 a month, or 4,860 a year. Swap in your own numbers.

For hospitality, OpenTable's Restaurant Impact Report puts the average cost of a no-show for a table of two at £55.70. Its restaurateurs also reported turning away other bookings (60%), wasting food and stock (48%) and struggling to forecast staffing (41%). The direct loss is only part of it.

Will asking for a deposit put customers off?

Usually less than owners fear, provided the deposit is modest, refundable and clearly explained. In the same OpenTable report, 44% of diners said a small deposit or card hold would make them more likely to honour a booking, and diners said they would accept an average of £35 per person.

Older UK data points the same way. In a 2023 Elavon and Yonder survey of 1,103 adults, 42% admitted they do not always honour bookings. Of those, 44% said a 10% deposit would encourage them to turn up. The people who cause no-shows are the ones a deposit nudges.

Our view at Braynex Services is that the fear is aimed at the wrong target. Customers rarely object to a deposit. They object to a deposit that feels like a trap: unclear terms, no refund route and no way to change the booking.

Should I start with deposits or with reminders?

Start with reminders. They cost almost nothing, upset nobody and work. Add deposits only where a no-show hurts most, such as long appointments, peak slots or new customers. A blanket deposit on every booking is the heaviest tool, and you often do not need it.

The evidence on reminders is encouraging. One 2025 clinic improvement project reported a 14.81% fall in no-shows after 24 hour text reminders, and another clinic study reported 13.1%. I have only seen these through search summaries, so treat them as indicative. A six month study of 1,193 appointments found no significant difference between phone, email and SMS. Having a reminder matters more than the channel.

OpenTable's restaurateurs show the same ordering. Confirmation reminders (43%) were the most used tactic, ahead of cancellation windows (36%), deposits (32%) and SMS reminders (29%).

When should I send appointment reminders?

Send three messages: an instant confirmation, a reminder about 48 hours before, and a short final text on the morning of the appointment or the day before. Spacing matters because the middle reminder gives people time to reschedule while you can still refill the slot.

1. Instant confirmation: date, time, address, price, and your cancellation terms in one plain sentence.
2. 48 hours before: a reminder with a clear "change or cancel" link. This is the message that rescues slots.
3. Morning of, or 24 hours before: a brief text asking for a one tap confirmation, with parking or arrival details.

Use SMS for the last two if you can. It is quick to read, and 42% of the self-confessed non-honourers in the Elavon survey said SMS reminders would encourage them to turn up.

What is a fair cancellation policy?

A fair policy lets customers cancel free of charge until about 24 hours before, then applies a clear fee or deposit forfeit after that. A ResDiary survey, which I have seen only in search results, found 33% of customers think up to 24 hours is fair, and fewer than 20% think 12 hours is.

Resist the urge to make it strict. A 2025 experimental study of restaurant cancellation policies (Kim et al., in the International Journal of Consumer Studies, also seen only as a summary) found that strict policies and complicated cancellation methods lowered no-show intentions but also lowered booking intentions. Its conclusion: lenient policies and easy cancellation help bookings and reduce no-shows.

That is the counterintuitive point. Making it easy to cancel reduces losses, because an early cancellation is a slot you can resell, and a silent no-show is not.

How does one tap rescheduling reduce no-shows?

Many no-shows are not people who never intended to come. They are people whose plans changed and who could not be bothered to phone. A reschedule link in every reminder turns a silent no-show into a rebooking, often with enough notice to fill the gap.

The link should open straight onto available times, with no login and no app download. Put it in the 48 hour message and again in the final text. If rescheduling means ringing during opening hours, you have effectively asked customers to find a reason not to tell you.

A good setup also offers a waiting list: when someone cancels, the slot is offered automatically to people who wanted that day.

Why does owning my booking system matter here?

Because reminders, deposits and rescheduling are only as good as the system running them, and on a rented platform you accept someone else's rules. You cannot always choose the message wording, the deposit logic or who owns the customer data.

Consider a nail salon we worked with. It was paying Fresha about 1,800 a month in commission. It moved to its own booking system at 35 a month, saving roughly 21,000 a year. The saving was the headline, but the salon also gained control of its own policy: its own reminder timing, its own deposit rules and a customer list it actually owned.

That is our broader position at Braynex Services. Rented platforms can change terms or fees overnight. Your bookings, your data and your customer relationships are better held in infrastructure you control.

What is a sensible plan for the next 30 days?

Work it in order of cost and risk: measure first, then add reminders, then tighten policy, then add deposits selectively. Each step is small, and you can see the effect before taking the next.

• Week 1: count last month's no-shows and late cancellations, and run the cost formula.
• Week 2: switch on the three step reminder sequence with a reschedule link.
• Week 3: publish a plain 24 hour cancellation policy and put it on the booking page and confirmation.
• Week 4: introduce a small refundable deposit for your costliest slots and new customers only, then compare your numbers.

A word of caution on vendor claims. OpenTable says restaurants using deposits through its system saw a 60% reduction in no-shows. That is a vendor figure rather than independent research, so treat it as directional. Your own before and after count is the number that matters.
