The project is a custom solution for a Food Delivery Business in Guatemala. Our company worked on a system that consists of three apps: the first one is designed for customers, the second is for delivery men, and the third app is administrative and aimed at admins, staff managers, call centers, and delivery men for restaurant service quality control. To implement the project, Celadonsoft’s mobile app development services and web app development services were contracted.

System structure:
  • Web app
  • Mobile app
  • Cloud server
  • Admin interface
  • iOS
  • Android
  • Delivery
  • 7 months

The Goals of the Food Delivery App Development

Surely, the primary goal is to elevate the service of the food and beverage venture. For that, the client came up with the idea to develop a stable and smoothly functioning mobile app and web platform for restaurant management and delivery service. The client reached us for end-to-end food delivery app development and website with a ready-made design. Any attempt to change it was turned down. The design must have been the spitting image of what was provided in Figma.

What the Client Brought to Order the Restaurant App

The app owner trusted us and put forward a detailed app idea, its functionality, and ready-to-wear UX/UI.

Challenges We Encountered During Food Delivery Application Development

We tackled a daunting challenge, albeit on a more practical scale – to develop a food delivery app that allows users to effortlessly order and pay for their meals. The Payment gateway incorporation aspect demanded intricate technological solutions involving the global payment network VisaNet and NIT, a service dedicated to retrieving local tax info for restaurant clientele.

What We Offered for Excellent Food Delivery App Creation

We proposed to make an app that would be dressed to kill. To ensure a smooth and pretty-looking design, we have changed font sizes, spaces, and colors. We believe the changes did their work. What do you think?

Custom Food Delivery App: Functionalities added

While the client supplied us with documents, there was still much to uncover regarding the integration process. We worked our fingers to the bone to thoroughly examine all the details surrounding properly functioning payment integration in food delivery applications.

Celadonsoft’s Experience-Based Tips to Build a Food Delivery App

Integration with InFile (NIT), a Guatemalan Service for Invoice Subscription
The challenge: We had to handle and process massive amounts of documentation and responses from the service. Another challenge is the documents in Spanish. We encountered the complexity of understanding how the service works. What data should be entered in the fields of both the CSV document and the requested content?
Solution: We got the translation of the documentation and other data into English. We sent multiple requests to the service and analyzed their responses. Having all the information, we have found a way to implement it by using the cut-and-try approach.
Cybersource. Integration With the Payment System
Challenge: There is a lack of documentation for node.js REST API. We had an access-only service with test routines and a GitHub repository with examples.
Solution: We got down to self-education on this matter, which took a while. But resulted in the aggregation of different examples of code into a single one. This worked out!
Strapi, CMS for API Creation
Challenge: Strapi is not flexible. Many microservices and plugins, like, SendGrid, auth providers, etc., have reduced functionality. Database handling was quite a challenge, too - complex aggregation queries can not be made using standard Strapi methods. And dear Bugs, of course. They were spotted using the count method with query parameters (bugs on deep filtering). The Strapi version was 3.6.6.
Solution: Celadonsoft’s developers have reworked and modified many components and modules. To solve the database issue, we’ve made custom database queries via knex.js using MySQL syntax.

Food Delivery App Design 

We have made a logical, catchy, and user-friendly design. The challenge was the client’s wish for the food ordering app development to stiffly follow the original design in Figma. The designer’s suggestions were taken hard.

Key Gains of Restaurant Food App

We added several kicky components for both the mobile app and web platform to create the best tech example to be followed and make the UX pure bliss.

Food Delivery Mobile App Development for a Carrier: 

  • Built-in GPS powered by Google Maps to monitor delivery time;

  • In-app calls to a client or call-center 
  • Customized data picker
  • In-app translation from English into Spanish and back

Website for Admins:

- Sidebar implementation that depends on the authorized user’s role.
- The website implementation, with its division into 3 roles of Admin panel, Call center, and Store manager, was a complex task. The call center was especially ticklish as it was necessary to blend a large scale of the functionality on one page

  • User search
  • Selection or creation of a delivery address and points of distribution;
  • Function to track drivers’ route and delivery time;
  • Distribution of received orders;
  • Enabling processing orders;
  • Daily menus update;
  • A shopping cart is enabled with multiple filters for categories and products in the catalog for sale in a particular store. By the way, the feature itself also contains a sufficient number of built-in functionalities);
  • Card and Cash payment method preference.


Our team has done its best to create a food delivery app that will produce a fruitful outcome. The solution gained popularity in the region, driving local adoption due to its conveniences. This led to increased consumer traffic, boosting sales and loyalty. New jobs were created for couriers and admin staff.
