More About Stack Soft
Stack Soft operates under the Onyma brand as a vendor of business support systems (BSS) targeted at telecom operators, Internet Service Providers (ISP), and other communications and digital service providers. Its core platforms are designed to handle billing, charging, customer management, and product configuration across prepaid and postpaid models, with a focus on convergent billing for multiple service types.
The company’s offerings are positioned for use in carrier-grade environments where availability, data consistency, and integration with network and back-office systems are mandatory. Typical deployment contexts include fixed and mobile telecom networks, broadband and IPTV services, enterprise connectivity services, and bundled digital products. Stack Soft’s systems are implemented as central components in an operator’s Business Support System (BSS) landscape, interacting with operational support systems (OSS), CRM front ends, financial accounting, and payment gateways.
Onyma platforms use standard enterprise architectures that support modular deployment, service-oriented integration patterns, and high-volume transaction processing. Integration commonly relies on Representational State Transfer (REST) and Simple Object Access Protocol (SOAP) web services, message queues, batch interfaces, and file-based exchange where required by legacy systems. In telecom environments, Onyma solutions are typically connected to network elements and mediation platforms using standardized protocols and interfaces that provide usage records and real-time session information to the billing core.
From a marketplace taxonomy perspective, Stack Soft can be categorized in enterprise billing and revenue management (billing and charging), customer care and CRM for telecom (customer management), and integration and implementation services (professional services). The Onyma product family is generally used as the billing and customer care backbone, providing account hierarchies, product catalog management, tariff configuration, discounting, and balance management, as well as support for invoicing, payments, and debt collection processes.
For enterprise and institutional customers, Stack Soft’s technology is relevant where there is a need to consolidate charging for multiple services on a single platform, manage large subscriber bases, and support complex tariff plans and partner settlements. The company also provides implementation, customization, and long-term maintenance services, which position it as both a software vendor and a service provider in BSS projects. In directories and procurement contexts, Stack Soft fits into categories such as telecom BSS platforms, convergent billing systems, subscriber management, and associated integration and support services.
