If you’re evaluating booking platforms for your restaurant, you’ll encounter two fundamentally different pricing models: commission-based and flat-fee. At face value, both seem reasonable. But the long-term cost difference between them — played out over months and years — can be significant enough to affect your margins in a very real way.
This post walks through the maths honestly: break-even points, real restaurant cost scenarios at different booking volumes, and a three-year comparison that shows what each model actually costs over time. No vague estimates — just the numbers.
The Two Models, Explained
The Commission Model
You pay a monthly platform subscription (typically €30–40/month) plus a commission on every booking. That commission is calculated as a percentage — often around 15% — applied to your estimated revenue from each booking (covers × your average meal price on file with the platform). The result varies by service type: weekday lunches, dinners, and weekend covers are often billed at different effective per-cover rates.
The key characteristic: your cost grows as your booking volume grows. Success increases your bill.
The Flat-Fee Model
You pay a fixed monthly amount regardless of how many bookings you take, what your average ticket is, or what time of day the reservation falls. No per-cover charges, no variable components, no end-of-month surprises.
The key characteristic: your cost is completely predictable. As you grow, the cost per booking actually falls.
The Break-Even Point: When Does Flat Fee Win?
The break-even point is the monthly booking volume at which the flat-fee model starts costing less than the commission model. Below that number, commission might appear cheaper (though the difference is small). Above it, flat-fee wins — and keeps winning more decisively as volume grows.
Using realistic market assumptions — a €40 subscription fee, a 15% commission on estimated revenue, a €22 average meal price (a conservative mid-range for Italian dining), and a flat-fee plan at €179/month — here’s where the break-even falls:
| Monthly covers | Commission model/month | Flat-fee model/month | Difference | Who wins? |
| 30 | €40 + €99 = €139 | €179 | −€40 | Commission |
| 50 | €40 + €165 = €205 | €179 | +€26 | Flat fee |
| 80 | €40 + €264 = €304 | €179 | +€125 | Flat fee |
| 100 | €40 + €330 = €370 | €179 | +€191 | Flat fee |
| 150 | €40 + €495 = €535 | €179 | +€356 | Flat fee |
Based on these assumptions, the break-even sits at approximately 43–45 covers per month. Below that, the commission model is marginally cheaper. Above it, flat-fee wins — and the gap widens significantly as volume increases.
Important caveat: commission rates, average meal prices, and subscription fees vary by restaurant and contract. Your actual break-even point may differ. The calculator linked at the end of this post lets you run the numbers using your own figures.
Three Restaurant Scenarios
Abstract break-even points are useful, but real decisions are made by real restaurants with specific booking profiles. Here are three representative scenarios — a smaller neighbourhood spot, a medium-volume trattoria, and a busier urban restaurant — compared across both models.
Scenario 1: The Quiet Neighbourhood Restaurant — 50 covers/month
A casual osteria in a residential neighbourhood. Mostly regulars, some walk-ins, a steady but modest booking flow. About 50 covers per month through the platform.
| Commission model | Flat-fee (Basic €179/mo) | |
| Monthly cost | €40 + €165 = €205 | €179 |
| Annual cost | €2,460 | €2,148 |
| Annual saving (flat fee) | — | €312 |
| Covers included | 50 (you pay for each) | Unlimited |
| Customer data | Platform owns | You own |
Even at modest volume, flat-fee is cheaper — and leaves room for booking volume to grow without the cost following it upward.
Scenario 2: The Mid-Volume Trattoria — 100 covers/month
A well-established trattoria with a mix of regulars and tourists. About 100 covers per month through the platform — a typical figure for a mid-sized independent restaurant in an Italian city.
| Commission model | Flat-fee (Basic €179/mo) | |
| Monthly cost | €40 + €330 = €370 | €179 |
| Annual cost | €4,440 | €2,148 |
| Annual saving (flat fee) | — | €2,292 |
| Covers included | 100 (you pay for each) | Unlimited |
| Customer data | Platform owns | You own |
At this volume, the flat-fee model saves over €2,200 per year — money that could fund a part-time staff member, a kitchen upgrade, or simply be retained as profit.
Scenario 3: The Busy Urban Restaurant — 150 covers/month
A popular restaurant in a city centre, managing a high booking volume through the platform. Perhaps a tourist-facing trattoria in Rome or a well-reviewed spot in Milan with strong repeat business.
| Commission model | Flat-fee (Basic €179/mo) | |
| Monthly cost | €40 + €495 = €535 | €179 |
| Annual cost | €6,420 | €2,148 |
| Annual saving (flat fee) | — | €4,272 |
| Covers included | 150 (you pay for each) | Unlimited |
| Customer data | Platform owns | You own |
At high volume, the cost difference becomes stark. €4,272 per year is a meaningful sum for any independent restaurant. And it only grows if the restaurant continues to expand bookings.
The 3-Year Comparison
Restaurant decisions are not made month-to-month. Choosing a booking platform is a medium-term commitment — and the cumulative cost difference over three years is even more telling than the annual figures.
The table below shows the total cost of ownership over three years across the three scenarios, assuming a 5% year-on-year growth in booking volume (which is conservative for a restaurant actively investing in its visibility).
| Restaurant profile | Commission — Year 1 | Commission — Year 2 | Commission — Year 3 | 3-Year saving (flat fee) |
| 50 covers/mo | €2,460 | €2,583 | €2,712 | ~€1,500 |
| 100 covers/mo | €4,440 | €4,662 | €4,895 | ~€7,500 |
| 150 covers/mo | €6,420 | €6,741 | €7,078 | ~€13,900 |
The 3-year saving for a mid-volume restaurant switching to flat-fee is in the region of €7,500. For a busier restaurant, it exceeds €13,000 over three years. These are not marginal differences — they represent a genuine and compounding financial advantage.
And this is before accounting for one additional factor: the commission model’s cost grows with your success. The more bookings you take, the higher your bill. Flat-fee inverts this logic entirely — growth costs you nothing extra.
What the Numbers Don’t Capture
The cost comparison above is straightforward. But there are additional dimensions to consider that don’t appear in a spreadsheet.
Customer data ownership
With a commission platform, the guest who booked through it is, in a meaningful sense, the platform’s customer — not yours. You cannot contact them outside the platform’s ecosystem, build a loyalty programme around them, or use their data to market directly. Over time, this represents a second, hidden cost: the value of customer relationships you could have owned but don’t.
Platform dependency risk
Commission rates are not fixed by law. They can — and do — change at renewal. A restaurant that has built its entire booking operation around a commission platform has very little negotiating power if rates increase. A flat-fee model removes this risk entirely: your cost is what it says in the contract.
The growth dynamic
A flat-fee model actively rewards you for growing. As booking volume increases, your fixed cost stays constant while your revenue grows — meaning the platform cost as a percentage of revenue falls. The commission model does the opposite: every new booking is another line item on the invoice.
When Might Commission Still Make Sense?
It’s worth being honest: for a restaurant at very low booking volume — say, fewer than 40 covers per month through the platform — the commission model may appear marginally cheaper in pure cost terms. This could apply to a restaurant just starting out with online reservations, or one that uses the platform as a secondary channel only.
However, even in this case, the cost gap is small (typically under €50/month), and the structural disadvantages of the commission model — no data ownership, costs that scale against you, dependency risk — remain present regardless of volume. Most restaurant owners who do the maths conclude that the predictability and control of a flat-fee model is worth the slightly higher entry cost at low volumes.
The Verdict
For any restaurant processing more than roughly 45 covers per month through a booking platform, the flat-fee model saves money — and the saving compounds significantly as volume grows. At 100 covers/month, you’re looking at over €2,200 saved annually. At 150 covers/month, over €4,200. Across three years, the cumulative difference can exceed €10,000.
Beyond the cost saving, flat-fee gives you two things the commission model structurally cannot: predictability and data ownership. Your monthly spend is fixed regardless of how well the restaurant performs. And every guest who books is yours — not the platform’s.
