GMI Analyst View
Based on our direct engagement with communication service provider procurement and technology leadership teams, we view the USD 24.8 billion global OSS/BSS market in 2022 as the foundation for the modernization cycle now being shaped by cloud adoption, network automation, and monetization priorities.
OSS/BSS Market Trends, Growth Drivers & GMI Forecast Outlook
The market's outlook rests on an uneven modernization cycle: operators must make billing, assurance, orchestration, and customer-management systems more responsive to new network services, while preserving continuity for large installed bases. That tension extends implementation timelines but broadens demand across software, integration, and managed operations.
Key Drivers
Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.
5G standalone operations increase the importance of real-time inventory, policy, service orchestration, and charging capabilities. The modernization requirement is not limited to faster network control; it is tied to the ability to package differentiated connectivity, enterprise services, and network capabilities into products that can be provisioned, rated, and supported without manual intervention. This favors vendors that can modernize discrete functions while fitting into an operator's wider technology estate.
IoT introduces a different operating model from conventional mobile billing. A platform must accommodate a broad range of device behaviors, service tiers, partner relationships, and connectivity profiles while maintaining low unit economics. That creates demand for modular catalog, rating, assurance, and analytics capabilities, particularly where operators are pursuing industrial connectivity, managed IoT, or multi-country service propositions.
ODA-aligned modernization is also changing procurement from monolithic replacement toward component-level transformation. Operators can sequence changes around the commercial or operational domains that create the greatest constraint, but this approach heightens the need for integration, testing, data migration, and governance. Professional-services demand therefore remains closely tied to the software opportunity.
Key Restraints
Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.
Cloud migration is difficult to accelerate where billing, revenue assurance, customer data, and network operations are distributed across long-established systems. These systems often carry localized configurations, acquisition-era interfaces, and regulatory dependencies that cannot be lifted into a new environment without extensive data preparation and testing. The result is a hybrid operating period in which vendors must support both modernization initiatives and the maintenance requirements of legacy estates.
The BSS challenge is particularly acute because monetization depends on commercial processes as much as network functionality. Operators may have the network assets required to introduce new services, yet still lack the catalog, charging, partner-management, or customer-care capabilities needed to package and settle them efficiently. Investment therefore tends to be staged, with buyers prioritizing the business domains that most directly reduce launch friction or revenue leakage.
Legacy coexistence also changes the economics of platform transformation. A technically sound component architecture does not eliminate the practical work of reconciling data models, process ownership, and operating responsibilities across multiple suppliers. Vendors with credible integration methods, migration tooling, and delivery capacity are better positioned to convert architecture roadmaps into production deployments.
GMI Analyst View
We expect modernization timing to remain more consequential than headline demand. Large operators will continue to anchor contract value, but their programs are governed by capital allocation, operational-risk tolerance, and internal sequencing. Smaller buyers can adopt cloud-delivered capabilities more quickly, widening the buyer base while changing the mix toward recurring services and lower-complexity deployments.
OSS/BSS Market Segment Analysis
By Component
BSS Solutions
BSS solutions accounted for 40.0% of the global OSS/BSS market in 2025 and are projected to reach USD 26.2 billion by 2035. The category remains central because billing, charging, product catalog, customer management, and revenue assurance sit at the point where new network capabilities become monetizable offers. Demand is strongest where operators need to introduce more flexible bundles, enterprise propositions, and partner-led services without expanding manual operating work.
OSS solutions generated USD 10.01 billion in 2025 and are expected to represent 34.0% of the global OSS/BSS market by 2035. Network automation, service assurance, resource inventory, and orchestration are moving toward API-led and component-based designs, allowing operators to address individual operational bottlenecks without committing to a full-suite replacement. This creates opportunity for modular vendors, but it also increases the importance of interoperability and accountable systems integration.
Managed Services
Managed services were valued at USD 4.29 billion in 2025 and are expected to grow at a CAGR of 8.6% through 2035.

The model is especially relevant where modernization must proceed while service quality and regulatory performance remain uncompromised.
Professional Services
Professional services are projected to reach USD 6.11 billion by 2035 and accounted for 10.0% of the market in 2025. Migration planning, system integration, configuration, testing, and change management remain essential to component-based transformation. The need to manage parallel operations and preserve business continuity makes service intensity a structural feature of the market rather than a temporary implementation expense.
By Deployment
Cloud-Based
Cloud-based deployment represented 42.0% of the global OSS/BSS market in 2025 and is projected to reach USD 45.65 billion by 2035. Cloud adoption is most compelling for new service launches, digital channels, and greenfield programs because it provides a faster release cadence and operational flexibility. For established carriers, the opportunity is tempered by the need to preserve data integrity, performance, and process continuity while workloads transition from existing environments.
On-Premise
On-premise deployment generated USD 16.59 billion in 2025 and is expected to grow at a CAGR of 0.1% through 2035. Its persistence reflects the operational and commercial sensitivity of core billing and network-management functions, particularly at large operators with heavily customized estates. Vendors serving this installed base retain an important role in upgrades, support, managed operations, and hybrid integration even as the relative weight of on-premise environments declines.
By Operator Type
Communication Service Providers (CSPs)
Communication service providers generated USD 20.59 billion in 2025 and are projected to represent 70.0% of the global OSS/BSS market by 2035. CSPs remain the defining buyer group because their systems must coordinate extensive subscriber populations, multi-access networks, complex service portfolios, and high-availability processes. Their purchasing decisions increasingly center on whether a platform can support commercial agility alongside operational control.

Demand is emerging from private networks, distributed IoT operations, multi-cloud connectivity, and managed digital infrastructure. Cloud-delivered platforms are lowering implementation barriers for organizations that require operational visibility and commercial controls but cannot justify a carrier-scale deployment model.
By Enterprise Size
Large Enterprises
Large enterprises generated USD 21.74 billion in 2025 and are projected to represent 74.0% of the global OSS/BSS market by 2035. Their dominance reflects the scale and complexity of major operator and enterprise environments, where multi-year transformation programs involve large service portfolios, demanding availability requirements, and substantial integration needs. These accounts continue to reward suppliers that can demonstrate delivery capability at comparable operating scale.
SMEs
SMEs accounted for 24.0% of the market in 2025 and are expected to grow at a CAGR of 9.6% through 2035. Consumption-based pricing, SaaS delivery, and modular implementation are making OSS/BSS capabilities accessible to smaller operators and enterprises that previously relied on fragmented tools or outsourced processes. The segment's expansion depends on suppliers maintaining simpler deployment models while preserving the assurance and monetization features buyers require.
GMI Analyst View
We see architecture as the primary dividing line in segment performance. Cloud delivery broadens market access, while modular designs allow buyers to target high-priority billing or operational constraints first. Suppliers that connect commercial and network domains in a coherent platform proposition are better placed to expand within accounts than providers offering isolated functions without a credible integration path.
