Case study

Restaurant CRM: Your customer base is worth more than you think — up to €73,000 a year (a study of 1,709 restaurants across 18 countries)

Content

Every restaurant that takes online orders builds something each day that never shows up at the till: a customer base — a list of people who once ordered, sometimes came back, and some of whom left consent to be contacted. This base never appears on your balance sheet, yet it has real, measurable value — and it grows every month you operate.

We analysed over 13 million orders from the past 12 years across 1,709 restaurants (595 separate brands) in 18 countries to show how much your base is worth and how to turn it into real money.

Results

Value of a loyal customer
14×

A customer who comes back regularly is worth fourteen times more per year. An average one-time customer leaves ~€31 a year, while a loyal one (10+ orders) brings ~€420.

Loyal customers
7%

That's how many customers in an average restaurant's base order 10+ times. A narrow but most valuable group — and it grows over time (after 5+ years it's already 8%).

Base size
~2,890 customers

That's how many unique customers an average restaurant has in its base after 3–5 years.

Base value
€15,000–73,000

That's what the base of ~2,890 customers is worth for an average restaurant operating 3–5 years — depending on how you measure it (three methods below).

Marketing consents
33%

That's the share of customers who give consent to email or SMS contact in restaurants operating 3–5 years.

Base growth
×2

A single location after 3–5 years has more than twice the base it had in its first 1–2 years (after 5+ years — more than three times).

You can change your premises or menu tomorrow. Your customer base stays for years — and it's worth tens of thousands of euro.

Key takeaways

What this means for your restaurant?
There’s one conclusion: build your customer base in a CRM and communicate with it regularly — by SMS, email, in your app, or through a loyalty programme. Here’s why:

  • Your CRM base — not a single order — is the true value of your business. It’s worth tens of thousands of euro. The customer list stays with you — you can change your supplier or your menu, but your customer contacts, their order history, and their contact consents grow every month and are yours alone. 
  • Selling through a marketplaces like UberEats, JustEat or Doordash, you pay twice: once in commission, and once in lost profit — because you’re not building your own base.
  • A loyal customer is worth almost 14× more than a one-time one. The annual value of a customer who orders once is ~€31, while a loyal one (10+ orders) brings ~€420 — every year. That’s why building repeat business is cheaper than constantly chasing new customers.
  • Only 7% of the base are loyal customers — the rest is huge, untapped potential. Nearly 60% of the base ordered only once. That’s hundreds of people who already know you and just need a reminder to come back. Each of them who orders a second time is worth twice as much to you.
  • You can turn your base into revenue today. One SMS to a base of ~950 consents — even a reminder like “our seasonal pizza is back, order online” — brings ~€1,500 in sales (at an average basket of €16). And to a base of 5,000 consents, a single blast brings up to ~€8,000. Doing this monthly adds ~€19,000–98,000 in annual revenue — and the bigger the base, the bigger each send.
  • Your CRM base builds itself, in the background. You don’t have to do anything beyond selling through your own website and app. An average restaurant adds over 1,000 customers a year, and after five years has several times more than at the start. The longer you operate, the bigger the reach you get for free.
  • Customers behave similarly regardless of size or country. We checked this across 18 markets. Base structure, consent rates, and the share of loyal customers are nearly identical in Poland and abroad. This isn’t a local quirk — it’s simply how the restaurant business works.

How to start? Set up an account and launch sales on your own website and app — UpMenu will automatically start building your base.

One SMS to your base brings in €1,500 to €8,000 in sales, and you send it in three minutes. The cheapest customer is the one you already have.

The CRM module in UpMenu

UpMenu builds your customer base automatically — every order through your website or app feeds it with data and consents collected in line with regulations. And most importantly — this base belongs to you, independent of marketplaces and their commissions.

    In practice, the whole system runs itself:

    1. A customer orders through your website or app and leaves their contact details and consent.
    2. They land in your base — automatically, with no work on your part.
    3. Whenever you want, you reach out to them: an SMS with a promotion, a notification about something new, or points for their next order.
    4. The customer comes back and orders again — and you don’t pay a marketplace a commission for messaging your own customer.
    5. The longer this wheel turns, the more you earn for the same effort — the base grows, so each new message reaches more people.

    On a marketplace you pay twice: once in commission, and once because the customer never becomes yours.

    Results (broken down in tables)

    How customer value grows per year

    A customer’s value depends on how often they order. One loyal customer is worth as much per year as almost fourteen one-time customers.

    Customer typeOrders per yearValue per yearHow many times more than one-time
    One-time1€31
    Returning2–4€732.4×
    Regular5–9€1695.5×
    Loyal10+€42013.7×

    How we calculated it: these are real figures from over a million customers active in the past year (out of 13 million orders across the full sample), not estimates — for each customer we summed their revenue over the past 12 months and assigned a type based on the number of orders in that period. We validated the values across three consecutive years.

    How customer loyalty grows over time

    The longer you operate, the more loyal customers you have. Loyal customers make up from 1% of the base (at the start) to 7% (after 5+ years).

    How the customer and consent base grows

    The longer a restaurant sells through its own channel and the larger it is, the bigger the base it builds. And the bigger the base, the greater its value. (Revenue converted to euro.)

    How we ran the study (read on if you like details)

    Scope of data analysed. We analysed over 13 million orders from the past 12 years across 1,709 restaurants (595 separate brands) in 18 countries (incl. the USA, eurozone countries, the UK, Canada, Switzerland) — with at least 100 customers who placed an order (our “genuinely operating restaurant” criterion). All amounts were converted to euro at average exchange rates.

    Period studied. The data covers the full online sales history of the restaurants in the sample — from the first order (the oldest accounts are 12 years old) to the time of data extraction. Annual customer values were calculated from the past 12 months and validated across three consecutive yearly windows.

    Date of study. June 2026 (analysis of system data as of 28 June 2026).

    International consistency. Customer behaviour patterns are nearly identical regardless of country: base structure (one-time / returning / regular / loyal) is 62/25/8/5% in Poland and 62/25/8/4% abroad. Consent rates (27% vs 28%) and the share of regular and loyal customers (13% vs 12%) also match. This justifies combining all markets into one sample.

    Averages. All values are arithmetic means for each group. They give a full picture of potential — including both smaller and larger restaurants in each segment. In tables combining all sizes (e.g. loyalty over time), the largest chains inflate the average — which is why the figures for an average single location, the ones most relevant to a typical restaurant, are reported separately under “Key figures”.

    Definitions. “Customer base” means all customers ordering online — in UpMenu every online order automatically creates a record in the base (it does not include phone orders, marketplace orders, or dine-in). Revenue is counted from the full sales history, converted to euro, with outliers trimmed. “Consent base”: customers with active marketing consent (SMS or email).
