Wellchange is a Hong Kong software enterprise that provides ERP and CRM solutions to small and medium-sized businesses. Wellchange helps customers digitize back-office and front-office functions, including accounting, human resources, inventory, and customer management. The company operates through two distinct revenue models: project-based fees and recurring subscriptions. Project-based revenue comes from bespoke customized software and white-label software that other IT companies rebrand and resell. Recurring revenue comes from MR. CLOUD, a proprietary cloud-based platform that offers ten functional modules including sales management, email marketing, and file management through tiered subscription plans. Wellchange sells directly to customers across industries such as retail, e-commerce, and real estate, though it maintains a small staff and experiences high customer concentration. The company's strategy focuses on expanding its platform modules and entering new markets in Singapore and Australia. While Wellchange intends to grow through these international expansions and potential M&A, the business has recently seen a decline in scale.
