How Many Calls Does Your Restaurant Miss Each Day, and What Does It Cost You?

Samuel Martínez, 4 September 2026. 14 min read. Translated from the Spanish original.

The average restaurant misses 8 to 15 calls a day. If 40% were bookings, that's €1,200 to €3,600 a month lost. Here's how to measure it and what to do.

An average restaurant in Spain can miss a lot of calls each day. If you estimate that 40% of those calls were bookings and your average spend per head is around €40, you are letting a significant amount of money slip away every month. In restaurants with more phone traffic or higher spend per head, the figure can be even bigger. It isn’t a management problem, it’s a capacity problem: when the phone rings in the middle of service, nobody can stop to answer it.

This article explains how many calls a typical restaurant misses, how much money those calls represent, how to measure it without installing anything and what to do about the problem once you have put a number on it. It all rests on explicit estimates, which you can swap for your own figures, and examples that apply to any type of venue, from neighbourhood bars to 60-seat restaurants.

TL;DR

Why you don’t answer every call

The kitchen is flat out, three tables are waiting for the bill, two diners are asking about allergens and the phone rings. Who picks it up? Nobody. It isn’t negligence, it’s physics: there aren’t enough hands.

During service, the priorities are clear: first the customers who are already inside, then the phone. The trouble is that the caller doesn’t know that. As far as they’re concerned, your restaurant doesn’t answer. And if you don’t answer, they ring the next place.

Calls are also missed outside service. Many restaurants close between 16:00 and 20:00, just when people leave work and start organising Friday dinner. If the phone rings in that gap and nobody is there, someone else gets the booking.

At weekends and on bank holidays the volume multiplies. Picture a restaurant that gets few calls on a Monday and many more on a Saturday. If answering was already hard on Monday, Saturday is impossible. That is where the most money slips away.

How many calls an average restaurant misses

There is no universal figure and no reliable public study for Spain. As a working assumption, in our experience a mid-sized restaurant (30-60 covers) can miss between 8 and 15 calls a day. In larger venues or those with a lot of delivery traffic, the figure can exceed 20.

Take it as an order of magnitude, not as hard data: what counts is your real figure, and further down you’ll find how to measure it. On busy days (Friday, Saturday, the eve of a bank holiday) the share of missed calls tends to rise, because that is when the fewest hands are free for the phone.

Breakdown by time slot

Missed calls are concentrated in three slots:

If you add up the three slots, a restaurant may be missing between 50 and 100 calls a week. That is between 200 and 400 calls a month. Now it’s time to turn those calls into euros.

How much money each missed call represents

Not every missed call is direct money. Some are questions about the menu, some are wrong numbers and a small percentage is spam. As our own estimate, between 35% and 50% of incoming calls during service tend to be bookings or orders.

If you take a conservative approach and assume that only 40% of your missed calls were genuine bookings, and that 70% of those bookings would have turned up (because not everyone who books actually comes), you can work out the cost like this:

Example with 10 missed calls a day:

That figure falls if your average spend is lower or if the share of bookings among your calls is smaller. But it also rises if you miss more than 10 calls a day or if your average spend is above €40. In restaurants with a weekend menu at €50-60, each missed call can be worth more than €30.

Indirect cost: reputation and repeat custom

On top of the direct revenue, there is an invisible cost. A customer who rings twice and gets no answer doesn’t ring a third time. They may book somewhere else that night and like it. You haven’t just lost a booking, you’ve lost a regular customer.

A customer who has a bad first contact experience (a phone that isn’t answered, a long wait, an answerphone with no booking option) has far fewer reasons to try again. In a market where the competition is a click or a phone call away, that matters.

What happens when the customer rings and you don’t answer

The customer rings. It rings once, twice, three times, four. On the fifth ring, they hang up. They open Google Maps, search for “restaurants near me” and ring the next one. If that one answers, they book there. End of story.

That is the usual pattern: someone who rings and gets no answer rarely leaves a message or tries again. They ring the competition. In hospitality, where choice is wide and decisions are quick, this matters even more.

Some restaurants try to soften this with an answerphone that says “we’re busy, leave a message”. But few customers leave one. Most hang up and ring somewhere else. An answerphone that can’t take the booking doesn’t hold on to the customer.

The cost of missed calls outside opening hours

If your restaurant closes from 16:00 to 20:00 and the phone rings 8 times in that slot, you have missed 8 opportunities. Many of those calls come from people organising dinner for that same evening or the following day. By the time you ring back at 20:30, they have already booked elsewhere.

This problem is especially serious in restaurants that close between services. The window from 16:00 to 20:00 is when many customers make their plans. If you aren’t available, someone else will be.

How to measure your missed calls without investing

Before looking for solutions, you need to know how many calls you really miss. Here are three free or almost free ways to measure it.

Method 1: Your phone provider’s call history

Most phone providers (Movistar, Vodafone, Orange, MásMóvil) offer a web portal where you can see the history of incoming calls. It shows answered and missed calls. Ask for access to that portal or request a report for the last month.

Compare the number of incoming calls with the number of bookings and enquiries you have noted down. The difference is what you’ve missed. If your provider doesn’t offer a web portal, ring and ask for the list. It’s a standard service.

Method 2: Call-logging apps

If you use a mobile for the business, the phone’s own call log already distinguishes answered calls from missed ones. If your line is a landline or a virtual switchboard, the provider’s portal (method 1) gives you the same with date and time.

These logs don’t tell you what the customer wanted, but they give you the number of missed calls by day and time slot. With that you can already estimate the cost.

Method 3: Manual log over two weeks

If you can’t use technology, try this: for two weeks, make a note every time the phone rings and you don’t pick it up. Put a tick on a piece of paper next to the till. At the end of the day, count the ticks. Do it for 14 days in a row, including the weekend.

It isn’t scientific, but it gives you a real picture. If you see days with 12 ticks and days with 25, you know where the problem is. Then you apply the conversion formula we saw earlier and work out the cost.

What to do about the calls you can’t answer

Once you know how many calls you miss and how much money they represent, it’s time to decide what to do. Here are the most common options, ordered from least to most investment.

Option 1: Reassign tasks on the floor

If you miss fewer than 5 calls a day, the problem can be solved with internal organisation. Assign one person on the floor the job of picking up the phone whenever it rings. It could be the person on the bar or someone who isn’t in direct contact with tables.

This works in small restaurants with a low call volume. If the volume exceeds 8-10 a day, reassigning isn’t enough. You need another solution.

Option 2: Enable online booking

If a large share of your calls are bookings, one option is to offer an online booking system on your website or Google Maps. Platforms such as TheFork, ElTenedor or your own systems let the customer book without ringing.

The catch: in mid-sized restaurants, a good part of the customers still prefer the phone. Also, platforms such as TheFork charge a commission per diner or a monthly fee. You can read more on this topic in Booksy, TheFork y compañía: por qué tus clientes no son tuyos.

Option 3: Hire someone for the phone

If you miss more than 15 calls a day and the cost calculation exceeds €2,500 a month, hiring someone part-time just to answer calls may pay off. Hiring someone solely to answer the phone is a considerable fixed cost.

Before hiring, measure for two full weeks and make sure the volume justifies the expense. If the calls are concentrated on just two days (Friday and Saturday), it may not be worth having someone all week.

Option 4: Automated phone answering system

There are systems that answer the phone automatically, take the booking, answer frequently asked questions (opening hours, location, whether you take groups) and alert you via WhatsApp or email when there is a new booking. These systems can be advanced answerphones or AI phone agents.

The advantage is that they work 24/7, never take a day off and usually cost less than hiring a person. The drawback is that they need initial set-up and not every customer is comfortable talking to an automated system, although that is changing fast.

Every restaurant has a different volume and budget. The important thing is to measure first, work out the real cost and then decide. If you are losing €1,200 a month in calls and the solution costs €300, the return is obvious. If you are losing €400 and the solution costs €600, it isn’t worth it.

Common mistakes when trying to fix the problem

There are three mistakes I see repeated in restaurants that try to sort out missed calls.

Mistake 1: Setting up an answerphone with no booking option. The customer rings, hears “we’re busy, leave your message” and hangs up. It solves nothing. If you’re going to put in an answerphone, make sure it at least takes the booking or redirects to an online booking system.

Mistake 2: Assuming everyone books online. In medium-sized and small restaurants, the phone is still a very important booking channel. If you shut the phone channel, you lose everyone who prefers it.

Mistake 3: Not measuring before acting. Hiring someone or installing a system without knowing how many calls you miss is throwing money away. Measure for two weeks, work out the real cost and then decide. You may find the problem is smaller than you thought, or that it’s concentrated on two specific days and you need a targeted solution, not a permanent one.

How this relates to other contact channels

The phone isn’t the only channel through which bookings arrive. There is also WhatsApp, the website form, Instagram Direct and, in some cases, email. Each channel has its own share.

The split varies a lot from one restaurant to another, so measure yours. As a rule, the phone comes first, followed by WhatsApp; online booking and social media carry less weight.

If you only optimise the phone and leave the other channels unattended, you are still losing bookings. Ideally you would have a system that unifies all the channels, or at least covers the two main ones: phone and WhatsApp.

At STAKKER we design automation solutions that bring calls, WhatsApp and the website together in a single flow. Every case starts with a free diagnosis to see which channels are a priority in your restaurant and what real volume you handle. You can request yours via contact.

When it makes sense to invest in an automated system

Not every restaurant needs an automated system. If you miss fewer than 5 calls a day and your average spend is low, it probably isn’t worth it. But if you meet two or more of these conditions, it’s worth evaluating:

In those cases, a system that answers calls automatically can help you recover some of the bookings you are currently losing.

Frequently asked questions

How do I know how many calls I miss if I don’t have any system installed?

Ring your phone provider and ask for the history of incoming calls for the last month. Compare it with your record of bookings and enquiries you’ve noted down. The difference is what you are missing. Some providers offer an online portal where you can see answered and missed calls in real time.

Is every missed call lost money?

No. Some are spam, wrong numbers or enquiries that wouldn’t have converted. As our own estimate, between 35% and 50% of missed calls during service tend to be real bookings or orders. The rest still reflects badly on your brand.

Is it worth hiring someone just for the phone?

It depends on the volume. If you miss more than 15 calls a day and your average spend is over €35, hiring someone part-time can pay off. But before adding to your headcount, measure for two weeks and work out the real return. There are cheaper automated alternatives.

Is an answerphone any use?

It lets the customer know the restaurant exists and what the opening hours are, but it doesn’t hold on to the booking. Most customers hang up and ring somewhere else. A system that takes the booking or answers basic questions is far more effective than a recorded message.

Do customers prefer to book by phone or online?

In medium-sized and small restaurants, the phone is still one of the main booking channels. The website works well in large or highly digitalised restaurants, but the phone remains the dominant channel in most cases.

Can I measure missed calls without changing provider or installing anything?

Yes. Most providers give you access to a web portal or an app where you can see the call history. If not, you can request it by email or phone. You can also use free call-logging apps on the business mobile, although they don’t always distinguish between answered and missed calls.

Next step

If you want to know how many calls you miss and how much they are costing you, start by measuring. Ask your provider for the history, use a logging app or note it down manually for two weeks. Once you have the number, apply the formula in this article and work out the real cost.

If the cost justifies acting, you have several options: reassign tasks, enable online booking, hire staff or install an AI phone agent that answers calls 24/7. Each option has its own return and its own cost.

At STAKKER we design automated answering systems for restaurants. Every project starts with a free diagnosis in which we measure your real call volume, identify what percentage are bookings and calculate the expected return. If the system isn’t worth it, we’ll tell you. Request your diagnosis via contact.
