How to increase restaurant sales with online ordering

Slovakia's restaurant industry grew in 2025, but much of that growth came from menu price increases rather than actual volume gains, according to Euromonitor's Consumer Food service in Slovakia analysis. Operators leaned heavily on promotional activity to bring customers through the door as new legislation, a sugar tax, and revised VAT rates pushed up costs. That pattern tells a clear story: raising prices has a ceiling, and restaurants that want sustainable revenue growth need a different strategy.
Online ordering is that strategy for a growing number of Slovak restaurants. For restaurant owners in Bratislava, Košice, Nitra, or Žilina who are already on a delivery platform or considering one, the question is not whether online ordering can grow revenue. It is how to make sure it does.
Does online ordering actually bring in new customers?

Yes, but the mechanism matters. When a restaurant lists on a delivery platform like the Wolt App, it becomes visible to customers who may never walk past the front door. A family in Petržalka searching for Thai food on a Tuesday night discovers a restaurant in Ružinov they did not know existed. A student in Košice orders from a café they have never visited. These are incremental orders, sales that would not have happened without the platform.
The research by Li and Wang confirms this pattern: Platform-driven orders tend to supplement rather than replace dine-in traffic. That said, simply being listed is not enough. Restaurants that invest in their online presence, including high-quality menu photos, clear item descriptions, and accurate pricing, consistently outperform those that treat their online listing as an afterthought.
What should a restaurant change about its menu for online orders?

Think of your online menu as a separate product. Customers ordering from home behave differently than customers sitting at a table. They scan faster, rely more on photos and descriptions, and are more likely to add items when prompted with bundles or combos.
Start with your most popular and most profitable items. Remove anything that does not travel well or requires complex kitchen modifications. This ties directly to how your delivery operation is set up in the kitchen. Our guide on how to improve your restaurant delivery setup in Slovakia covers the operational side of what travels well and how to test it before you commit menu space to it.
Then structure the menu to encourage larger orders: meal bundles, family-size options, and drink pairings all tend to increase average order value without adding much operational complexity.
How do promotions fit into the picture?
Promotions can accelerate early traction or re-engage lapsed customers, but they work best as a targeted tool rather than a permanent discount. A first-order discount aimed at new customers in your delivery zone is a different proposition from a blanket 20% off that eats into margins on every order.
The Wolt Promos system lets you run targeted campaigns, and the guide to choosing the right offers walks through which formats work for different goals: acquisition, reactivation, or increasing order frequency.
Keep in mind: The profitability of any promotion depends on the full cost picture, including food, packaging, commission, and the discount itself. A promotion that brings in 50 new orders but loses money on each one is an expense, not a growth strategy.
Why do repeat customers matter more than new ones?
Retention often produces stronger returns than acquisition. A customer who orders once and never returns represents effort that did not compound. A customer who orders weekly for six months represents revenue that builds on itself, without new acquisition cost after the first order.
Wolt+ is Wolt's customer subscription, offering 0 euro delivery fees on eligible orders, discounts on select items, and access to exclusive offers. Because subscribers pay for the membership, they tend to use the app more actively than non-subscribers, which means restaurants visible to this segment are positioned in front of a more engaged pool of customers.
Actual ordering frequency varies by market and cuisine. Beyond subscriptions, loyalty comes down to food quality, order accuracy, and the small details that make a customer choose your restaurant again instead of scrolling past it.
Track your new-versus-returning customer ratio in the Analytics & Insights dashboard. If the ratio skews heavily toward new customers with few returning, that is a signal to focus on the experience rather than the reach.
What role does visibility play in driving sales?
On a delivery platform, visibility works differently than foot traffic. Your restaurant's position in search results, featured placements, and category rankings all determine how many customers see you before they see a competitor.
Several factors influence visibility: Your venue rating, order accuracy, how often you are open during stated hours, and preparation speed. Each is something you can directly control. The venue rating guide covers the specifics.
For an additional push, Wolt Ads offers in-app placements on a pay-per-result model, so you pay when the ad drives an outcome, not just an impression.
Where should a restaurant start?
The highest-impact starting point is getting the basics right: a focused online menu with good photos, accurate preparation times, and a kitchen workflow that handles delivery orders without delays. Once those foundations are solid, promotions, ads, and loyalty tools amplify results rather than paper over problems.
If you are not yet on the platform, getting started as a restaurant on Wolt takes a few steps. If you are already listed, the Merchant Portal is where you manage your menu, track performance, and find recommendations for your venue.
