Challenges

We needed to create a solution that could be easily customized for any building complex, whether big or small, residential or commercial. Also, the software should include features for both administrators and residents to streamline communication between them and simplify the process of handling requests.

Project highlights

Every building requires a tailored approach to property management. Take two residential buildings, for instance, each with its own specific needs. One has a paid parking lot, while the other follows a car-free lifestyle. In the first building, features like parking passes and payment system integration are essential, while in the second they aren’t. This principle also applies to commercial buildings: each one has distinct requirements that call for customized management solutions.

Our task was to create a universal property management system for both residential and commercial buildings. To achieve this, we developed a feature set that encompasses various use cases, letting clients pick the functionalities they need. The system also had to be highly customizable to adapt branding elements like colors and logos for each client.

To understand how housing estates operate and what they need, we kicked things off with the discovery phase.

Discovery phase

The project began with a client interview to uncover core pain points and needs in property management. We also did competitor research to find the strengths and weaknesses of existing solutions.

Our team’s experience also contributed to this project. As each of us lives in a residential complex, and our office is located in a business center, we had a clear vision of what property residents would expect to have in such a solution. This mix of research and personal experience gave us a solid foundation to develop a proper PMS.

A single digital space for efficient property management

In six months, our team developed a property management system that included a web application for administrators and Android and iOS mobile apps for users.

Android App

Native Android app for residents and on-site staff. Residents can pay bills, submit maintenance requests, and receive building updates right from their phones.

iOS App

Native iOS app that keeps residents connected to their homes. Browse available services, request support, and get real-time notifications about important building events.

Web App

Admin web portal for property owners and managers. Configure buildings and units, track occupancy and payments, and handle service requests in one place.

Delivering a positive user experience: features for residents

As we were building a PMS for various types of real estate, we aimed to make the app useful and convenient for property owners, tenants, and residents/employees alike.
Here are the core features we implemented for mobile app users.

User approval and role assignment

When a user downloads the app, they submit an application to join the system. The administrator reviews it, assigns a role (resident, tenant, or employee), and grants access. This ensures security and proper user management while preventing unauthorized system entry.

Entry pass generation and access management

After approval, the system generates an entry pass for residents, tenants, or employees. Our PMS supports QR codes and EAN 13 barcodes, integrating with existing security systems. Users can also request temporary passes, improving security by tracking who enters and exits.

Concierge and smart service booking

Residents and employees can request various services, such as cleaning, courier delivery, or household maintenance. They can also call professionals, including electricians and plumbers, simplifying everyday tasks. The app ensures quick service booking with minimal effort.

User approval and role assignment

We designed tailored service booking forms to improve user experience. For example, when reserving a tennis court, users can order sports gear like rackets and balls. The courier form, on the other hand, is streamlined to focus solely on delivery, making the process efficient.

User approval and role assignment

Users can browse and book services inside and outside the complex, such as reserving a restaurant table, booking a tennis court, or securing a co-working space. This provides convenience, allowing residents and employees to access various amenities with ease.

Digital parking pass and payment integration

Users with cars can apply for a parking pass and pay via the app. Families can register multiple vehicles. Our team analyzed API documentation for various payment systems, ensuring smooth integration with widely used solutions to optimize payment processing and user experience

Community news and local updates

Users stay updated on events within the complex and surrounding areas, including new sports centers, cafés, or community activities. This feature allows residents and employees to easily discover local amenities and stay connected with events, improving engagement.

Resident update hub and service notices

Residents receive push notifications about scheduled repairs, power outages, or other events affecting comfort. These timely alerts keep users informed about important updates, ensuring better planning and smooth communication for everyone within the complex.

Improving staff efficiency: features for administrators

Administrators, or building managers and owners, can use the web application to effectively manage the building. Here are the key functions they can perform through the app.

Approve new user applications

Managers can review and approve applications from new residents or guests, ensuring full security and control of the property access.

Post news

Admins can add updates and important announcements to keep residents informed about events and other relevant information.

Set up push notifications

Administrators can configure push notifications to alert residents about urgent matters, such as maintenance work or safety updates.

Monitor building information

The web app allows managers to view crucial information about the building with access to real-time statistics, for example, the number of available parking spaces, and more. It helps them manage resources effectively.

View information on residents and guests

Administrators can access relevant information on residents, including their phone number and apartment number. They also know the list of current guests in the building, which enhances security and ensures that all visitors are accounted for.
