For Burger Restaurants

The ordering system for burger restaurants

Burger concepts earn on combo meals, not individual items — yet platforms take 30% on the full order. GastroSystem gives you a menu builder, combo upsell and your own ordering system that keeps every euro of the total order.

What many burger restaurants know too well

Lieferando takes 30% on every order: on an €18 burger meal only €12.60 remains after commission — before any other cost
Combo upsell (burger + fries + drink) is awkward or impossible to configure on delivery platforms
Walk-in and take-away need fast till processing, not a slow platform interface
Smash burger, double patty, cheese sauce vs. ketchup — individual configuration fails over the phone
No customer data from platform orders; no loyalty programme possible
High fixed costs (grill, staff, cold chain) demand full margin on every revenue euro

How GastroSystem solves this

Menu builder with combo upsell

Create combo groups: burger + side (fries, sweet potato, salad) + drink (330 ml, 500 ml, shake) — each combination with its own price. The system automatically suggests an upgrade at checkout: 'Upgrade to large for €1.50?' Combo upsell increases the average order value without additional staff.

Patty and topping configuration

Configure single, double, triple patty with individual surcharges. Toppings as mandatory choice (cheese type) or optional extras (extra bacon, jalapeños, avocado). 'No onions', 'extra sauce' — as a free-text field or pre-set options. Everything lands clearly and unambiguously on the kitchen receipt.

Fast till processing on site

The integrated POS is optimised for speed: one tap per burger, combo groups expand automatically. Walk-in customers are served in under 90 seconds. Ideal for counter and take-away operations where waiting time directly affects customer satisfaction.

Your own loyalty programme instead of platform dependency

Every 10th burger free — digital stamp card in your app. Customers who order directly with you earn points; Lieferando customers do not. That gives regulars a real incentive to switch to your system. On average, customers in a loyalty programme order 2.3 times more frequently.

0% commission — full margin on every combo

You pay €79–299/month flat rate. With 300 orders at €18/month you pay €1,620 commission on Lieferando. GastroSystem costs €299/month — you keep €1,320 more. At a 12% gross margin that equals the net profit from 110 additional combo meals.

Cost example

A burger restaurant with 300 Lieferando orders per month and an average order value of €18 pays €1,620/month in commissions (30%). With GastroSystem Professional you pay €299/month — saving over €1,320 per month. Add combo upsell: if 20% of customers take a larger portion for €1.50 more, monthly revenue grows by an additional €90 at 300 orders — purely from the menu builder feature.

Can I offer combo meals with selectable sides and drinks?

Yes. You create combo groups with mandatory and optional extras: burger + side + drink, each from a selection. Each combination has its own price.

How does combo upsell work in practice?

You configure upgrades in the extras system: e.g. 'Large instead of regular for +€1.50' or 'Shake instead of soft drink for +€2.00'. The system shows the suggestion at checkout — customers confirm or skip.

Can customers customise their burger individually?

Yes. Customers can add, remove or change ingredients. 'No onions', 'double patty', 'extra sauce' — all configurable as pre-set options or free-text fields.

Does GastroSystem work for smash burger concepts and ghost kitchens?

Yes. The system is flexible for any burger concept — smash burger, gourmet burger, chicken burger, veggie burger. Ghost kitchen operators can manage multiple burger brands from one dashboard.

Can I stay on Lieferando in parallel?

Yes. Start with GastroSystem in parallel and gradually shift orders. Regulars get an incentive to order directly through the loyalty programme.

Is there a loyalty programme?

Yes. Digital stamp cards and bonus points are built in. You define the rule: e.g. a free drink or upgrade on every 10th order. Customers see their progress directly in your app.

How quickly can the POS process walk-in customers?

With quick access to the menu and pre-configured combo groups, a standard counter order takes 60–90 seconds. The system is designed for throughput during lunch hours and busy weekend evenings.
