Questions we hear a lot, answered in full.
Written from what we've built, not from what we've read. Every guide starts with the short answer.
How do you publish a company app on Google Play and the App Store?
As a company, you need a D-U-N-S number, organization developer accounts with Apple and Google, a public privacy policy and a store listing with screenshots and copy, then testing and review. Company verification usually takes longer than the code itself, so start the paperwork in the first week of the project, not the last.

Food cost is the cost of the ingredients in one portion divided by its selling price. Real margin, though, depends on the channel: for delivery you also subtract the platform commission and packaging. A price that works in the dining room can leave almost nothing on Glovo, so calculate every dish separately for dine-in and for each platform.

A virtual brand is a restaurant that exists only on delivery apps. It has no dining room and no sign over the door. It's cooked in an existing kitchen, by the same team and ideally from much of the same stock. It makes sense when you have idle hours and can fill a category missing from your area.

A restaurant app's price depends on its features, the platforms (web, iOS, Android), integrations with your POS and ongoing maintenance. At ZED-ZEN, websites, web apps and native mobile apps start from 1,500 RON, and the final price is set once we've agreed exactly what they need to do. Store account fees come on top.

Sales on delivery apps grow when you fix what customers see in the app: a menu built for each platform, photos that look good on a phone, prices calculated per channel and promotions picked from the platform's calendar. Then you measure orders every week, not likes, and adjust. Ratings and prep times hold everything together.

A loyalty app replaces the paper stamp card with a digital card on the customer's phone. They scan a QR code on the receipt or at the table to collect points and redeem them for products. The app also carries a daily deal and offers. Unlike paper, it doesn't get lost, and you can see who comes back.

A brandbook is the user manual for your brand. It covers your story and tone of voice, the logo with its variants and clear space, exact color codes, typography, image style, layouts and examples on real materials. Its job: anyone who works for you produces things that look like the same brand.

AI helps a restaurant with repetitive work: draft replies to reviews, daily reports written from the numbers, WhatsApp answers, and alerts when stock runs low or a supplier price rises. With an MCP connector, owners can ask Claude or ChatGPT directly about sales and stock. It doesn't cook and it doesn't replace a manager.

A presentation website's price depends on the number of pages, the features (ordering, payments, bookings), integrations and who handles hosting after launch. At ZED-ZEN, a 5–8 page presentation site starts from 1,500 RON as a one-off payment, with basic SEO, GDPR and the first year of hosting included.
