OASES provides aircraft maintenance, repair and overhaul (MRO) software for airlines, continuing airworthiness management organisations (CAMOs), and maintenance operators. Its integrated suite brings maintenance planning, airworthiness, materials management, line maintenance, and commercial management together around a shared set of data. The platform automates tasks such as tracking airworthiness directives and service bulletins, creating work orders, managing inventory, and recording maintenance actions. It also supports financial management, warranty tracking, regulatory reporting, and audit trails, helping organisations coordinate work, control costs, and reduce delays and aircraft downtime.

OASES connects with other aviation and business systems through its Gateway API framework and Workflow tools, while browser-based access supports use on computers and tablets. The company also offers implementation and project management, technical support, and OASES Academy, where customers can access courses, webinars, FAQs, and a community for sharing knowledge. An AI assistant, ASK OASES, is designed to analyse and present operational data and take actions. The software is hosted on AWS and includes security, backup, and recovery measures.
