MainBoss CMMS is maintenance management software from Thinkage Ltd., positioned as a “simplified maintenance solution.” It is designed for maintenance departments and brings service requests, work orders, equipment assets, preventive maintenance, spare-parts inventory, purchasing/receiving, and cost analysis into a unified system. Applicable industries include property management, manufacturing, mining, water treatment, power plants, schools, healthcare, hotels and resorts, and government facilities.
Based on the site content, MainBoss offers fairly comprehensive CMMS coverage: issue tracking, work order management, inspections and preventive maintenance scheduling, equipment asset management, inventory control, spare-parts location and replenishment optimization, purchasing/receiving, plus reporting and analytics. MainBoss also provides web capabilities: authorized users can submit work requests through a self-hosted website, while staff can view the work orders and requests assigned to them. Technically, it is not a typical cloud-only SaaS product; it is closer to an on-premises/self-hosted deployment. MainBoss uses Microsoft SQL Server to read and write data, and its web module is based on ASP.NET, requiring Windows and IIS.
The official site mentions a Free MainBoss System, with the option to add modules for expanded functionality, and supports scheduling a free demo. The product is split into MainBoss and MainBoss Basic. Basic is aimed at small and midsize maintenance departments, uses a modified Codebase database, is licensed by seat—that is, by the number of simultaneous users—and has a lower license cost than MainBoss. MainBoss, by contrast, is built around Microsoft SQL Server and is better suited to scenarios requiring stronger data management and web capabilities. Specific pricing and payment methods are not disclosed.
The advantages are that its feature modules are traditional but solid, covering the full maintenance management workflow; the free system lowers the barrier to getting started; and SQL Server is familiar to organizations with IT teams, making centralized data management easier. The drawbacks are also clear: the deployment stack is relatively old and heavily dependent on Windows/.NET/IIS/SQL Server; there is limited disclosure around modern SaaS essentials such as mobile support, APIs, third-party integrations, compliance certifications, and SLAs; and the web module still requires customers to host and configure it themselves.
MainBoss is better suited to small-to-large maintenance teams that already have Windows/SQL Server infrastructure and want local control over maintenance data, especially in facilities, manufacturing, and public-sector organizations. If a company prefers an out-of-the-box cloud SaaS product, mobile-first workflows, or extensive integrations, Fiix, UpKeep, MaintainX, Limble CMMS, eMaint, and similar options may be a better fit. Access from China cannot be determined from the site content; payment methods are also not disclosed. Domestic Chinese teams should carefully verify website accessibility, demo communication, payment options, and local implementation support.
