The ordering system for halal restaurants
Halal-certified businesses need to actively build trust with their guests: the certificate needs to be visible, the menu needs to explain which dishes meet which certification standard, and the app needs to work in the languages of the guest community. GastroSystem builds exactly that framework of trust, digital and scalable.
What halal restaurant owners know well
- Certificate not visible online
Your halal certificate hangs on the wall, but guests ordering via Lieferando or your website see nothing. Many guests order elsewhere simply because the certificate is not digitally visible.
- Multilingual guests, German-only menu
A significant portion of your guest base speaks Arabic, Turkish or English as their first language. A German-only menu creates friction and reduces conversion — particularly for delivery and pre-ordering.
- Shared kitchen or mixed product lines raise doubts
If your kitchen also handles non-halal products, guests need clear information about which items are halal-certified and which cooking utensils are separate. Without this transparency, trust erodes.
- Third-party platforms offer no differentiation
On Lieferando or Wolt, your halal restaurant appears next to non-halal competitors. Guests who specifically look for halal can't reliably identify you — and the platform captures the customer relationship, not you.
How GastroSystem helps halal restaurants
Halal certificate visible in the digital menu
Upload your halal certificate once — it appears as a seal on your restaurant page and on every product you mark as halal-certified. Guests can open the certificate document directly in the app. This eliminates the most common trust barrier and converts hesitant guests.
Multilingual ordering app
The app automatically detects the language set on the guest's device and displays the menu in Arabic, Turkish, English or German. You maintain the translations once in the dashboard. No separate menus to print, no manual switching.
Clear item-level halal labelling
Tag each item individually: '100% halal-certified', 'halal meat, shared kitchen' or 'vegetarian, halal-suitable'. Guests see the exact status for every dish before ordering. This level of transparency is not possible on third-party platforms.
Direct ordering channel — your brand, your trust
Your own ordering page with your name and your certificate. No comparison with non-halal competitors, no platform ranking that buries you. Guests who search specifically for halal food find you directly and build a relationship with your business — not with the platform.
Trust converts — directly
Halal guests tend to be highly loyal once trust is established — studies show repeat purchase rates of 60–70% among guests who trust a halal certificate. A direct channel with clear certificate display and a loyalty programme retains these guests without platform commission. At €10,000 monthly delivery revenue through Lieferando, switching to GastroSystem saves up to €3,000/month in fees.

Common questions for halal restaurants
Can I upload my halal certificate?
Yes. You upload the certificate as a PDF or image. It appears as a clickable seal in the app. You can update it any time you get a new certificate.
How do I mark only certain dishes as halal?
Every dish gets its own labels. You assign the halal icon only to dishes that are certified. Guests see only certified dishes when they use the filter, if they want to.
Does the app work in Arabic?
Not automatically yet. Your menu currently speaks German, English, Turkish, Croatian, Polish and Persian, Arabic isn't in there yet.
