Background story

As employee engagement positively influences the productivity of any company, business owners take actions to improve loyalty within their teams. Companies implement various platforms and apps as part of their workforce strategies to motivate staff to work more efficiently for the benefit of the company.

When employees have instant access to their financial records and know all details related to their salaries, they tend to trust their employers more. Our client turned to JatApp to help them develop a payroll solution that securely delivers financial information to users.

About the client

Our client is an international provider of financial solutions. With headquarters in Frankfurt, Germany, the company has offices all over the world and offers financial services to global businesses. It helps organizations enhance their efficiency and avoid expansion pitfalls.


As a global provider of payroll services, our client delivers a vast range of financial solutions for businesses, including a web application that enables employees to view their financial statements and payslips. To simplify the delivery of financial data to employees and make it more convenient, the company decided to create native mobile apps for Android and iOS.

The financial company turned to JatApp to develop a payroll solution that keeps employees informed about their current incomes. It took us 6 months to build payroll applications for Android and iOS.


We developed a payroll app that enables workers to quickly access payslips, annual statements, and net pay data.

  • Encrypted connection

    JatApp implemented HTTPS protocol to encrypt confidential information and protect it from unauthorized parties. The protocol allows for exchanging users’ personal data via a secure channel and preserves the data from being stolen.
  • Cryptographic algorithms

    We inspected the source code for vulnerable cryptographic algorithms and adjusted configurations. Thanks to this, all the algorithms that were known for their weaknesses were replaced with more secure alternatives, while remaining in line with industry standards.

Technologies Used

  • Java
  • Swift


The application we built lets employees access their payroll history at any moment.

Net pay

On the home page, the staff can view their net salaries for a specific period. Each employee seamlessly views their payment records and is completely aware of their current financial situation.


Team members enjoy full transparency and can instantly access financial records with tax deductions. Also, users can easily download and store all documents they need.

Annual statements

Users get quick access to their annual statements and analyze their income throughout the year.
