Your best customer just placed their last order.
Restaurants lose their most valuable guests every month — without noticing. Because they don't know who their regulars are, they can't keep them. It doesn't have to be this way.
The story that repeats itself every day
In thousands of restaurants, this happens every single day — unnoticed.
Mr. Smith orders three times a week from his favourite pizzeria. Always the same Margherita, sometimes a Coke on the side.
Over two years he placed 312 orders. He knows the menu by heart. He recommends the restaurant to friends.
That's how much Mr. Smith spent at this restaurant. He's one of the top 5 customers — but nobody knows.
One bad delivery. No call, no apology, no voucher. Mr. Smith now orders somewhere else.
The restaurant never noticed. No alert, no warning, no signal. One of its most valuable customers simply disappeared — and nobody followed up.
The numbers that hurt
Customer retention isn't a soft topic — it's the biggest lever for profitable growth in the restaurant industry.
more expensive to acquire new customers
Winning a new customer costs five times as much as keeping an existing one. Yet most restaurants invest only in acquisition.
of revenue from 20% of guests
The Pareto principle applies to restaurants too: one fifth of your guests generate four fifths of your revenue. Do you know which 20 percent?
people hear about a bad experience
A happy regular recommends you to 9 people. An unhappy one tells 16. Without a feedback system, you'll never hear about the bad experience.
Why restaurants don't know their regulars
It's not about willingness — it's the system. Four structural problems prevent restaurant owners from identifying their most valuable guests.
-
Orders via platforms = no customer data of your own
If you sell through Lieferando, Wolt or Uber Eats, you receive orders — but not customers. The platform owns the data, not your restaurant.
-
No system to recognise regulars
Most POS systems count transactions, not customers. Whether someone orders for the first or the hundredth time — the register treats them the same.
-
No way to detect churn
When a regular stops ordering, there's no signal. No alert, no report, no warning. Revenue drops — and nobody knows why.
-
No channel to win customers back
Even if a restaurant notices a regular is missing: without email, phone or app there's no way to bring them back.
Before vs. After: What changes with customer data
The difference between a restaurant that knows its guests and one that doesn't.
Anonymous guests
Every order is a faceless transaction. You don't know if someone is ordering for the first or hundredth time.
Known customer profiles
Every order is automatically linked to a customer profile. You see order frequency, favourite dishes and customer value at a glance.
Lost regulars
Your best customer stops ordering. You notice months later — if at all.
Automatic churn alerts
KundenSystem detects when a regular suddenly goes silent and suggests you win them back with a personal offer.
Marketing in the dark
You spend money on advertising without knowing who you're reaching. Discounts go to everyone — including new customers who would have ordered anyway.
Targeted campaigns
Send offers only to the right customers: loyalty bonuses for regulars, welcome vouchers for new customers, win-back campaigns for churners.
KundenSystem: Your guests deserve to be recognised
KundenSystem is the CRM built specifically for restaurants. It turns anonymous orders into real customer relationships — automatically, GDPR-compliant, and right inside your GastroSystem.
Automatic customer profiles
Every order is matched to a profile — by email, phone number or app account. At a glance you see: order frequency, favourite dishes, total revenue and last order.
Digital loyalty programmes
Create stamp cards, point systems or VIP tiers. Your guests automatically earn points and redeem rewards — no paper cards, no effort for your team.
Smart campaigns & win-back actions
Send push notifications or emails to the right customers at the right time. Birthday discounts, churn alerts, loyalty bonuses — all automated.
Frequently asked questions about customer retention in restaurants
Answers to the most important questions about regulars, loyalty programmes and KundenSystem.
Do I really need a CRM as a restaurant?
Yes — if you don't want your best customers to quietly switch to the competition. A CRM doesn't have to be complicated: KundenSystem automatically collects data from every order and makes it actionable. No manual effort.
How does KundenSystem recognise my regulars?
Every order is linked to a customer profile via email, phone number or app account. The system automatically calculates order frequency, average order value and total revenue — so you spot your top customers instantly.
Is it GDPR-compliant?
Absolutely. KundenSystem only stores data that customers voluntarily provide when ordering. All data is stored in the EU, deletion requests are processed automatically, and there is no sharing with third parties.
What does KundenSystem cost?
KundenSystem is included with GastroSystem Professional (€299/month net). No extra charges, no per-head fees, no hidden surcharges.
Does it work with walk-in customers too?
Yes. As soon as a guest orders through your web app, a profile is created automatically. On the next order the system recognises them again — even without an app download or account creation.
How long does setup take?
No time at all. KundenSystem runs immediately when you use GastroSystem. Customer profiles are created automatically from the first order. Loyalty programmes can be configured in under 5 minutes.
