Client profile
The client firm is one of the top telecommunication services providers operating in the USA. Having a history of more than three decades in this industry, the firm has earned a good reputation in the market. It offers mobile, internet, and landline services to customers residing in 24 different states of America.
The provider has a subscriber base of nearly 10 million people. It is facilitated by a cellular tower network of over 7,000 sites. The company has a staff of about 2,300 employees and earns revenue of nearly $840 million per year. At this scale, billing accuracy and speed become crucial for customer retention.
Technical challenges
The rapid expansion and tough competition put pressure on the client’s outdated invoicing system. Every new product launch or pricing change exposed how the underlying codebase infrastructure needs an upgrade. Four challenges stood out clearly:
Scalability limitations
The legacy platform’s complex, monolithic codebase made it difficult to adapt to new products, services, and market demands.
Maintenance expenses
Maintaining the old invoicing system required particular knowledge and was extremely labor-intensive.
Security gaps
Outdated security protocols and unpatched vulnerabilities left customer billing data exposed to breaches and compliance risks.
Customer experience
An outdated user interface made it difficult to manage billing inquiries and left subscribers frustrated. It led to customer dissatisfaction and higher churn.
Our solution
To begin, our team conducted a thorough needs analysis. It involved all stakeholders from the billing and compliance to customer service departments. We identified every problem with the current system and established goals for the modernized platform.
Drawing on Softweb Solutions’ proven Azure architecture expertise, a team of our cloud experts led a phased migration of the client’s billing platform. We upgraded the system with a modern data layer and AI-ready foundation on Microsoft Azure. This directly resolved the limitations of their legacy software.
Infrastructure for elastic scalability in the cloud
Our cloud engineering team migrated the client’s billing system to Microsoft Azure. It replaced the client’s rigid on-premises servers with a highly elastic cloud setup. We restructured the legacy monolith into independently scalable microservices to power every billing process.
Cloud-native billing platforms typically cut total cost of ownership by 30 to 40 percent industry-wide. The client can now launch new pricing plans and promotions within days instead of months. This flexibility keeps the company competitive as customer demand and network usage keep rising each quarter.
Feature-rich billing platform powered by Azure SQL
We migrated the client’s billing data from an aging SQL Server environment to Azure SQL Database for better speed. On top of that, our team built a modern billing platform with personalized plans and dynamic pricing. Real-time usage tracking now updates customer accounts the moment a service gets consumed.
Customers can view live usage, adjust plans, and understand charges without contacting support. Dynamic pricing lets the client test new offers and respond quickly to competitor moves. The finance team also gained faster, more accurate reporting across every product line and region.
Layered protection approach for compliant security
We adopted a layered approach for protecting all data by implementing an encrypted transfer of data and role-based access control. Our workflow is aligned with all industry regulations concerning privacy, retention, and customers’ consent for their data use. Our continuous vulnerability scan helps us detect any weaknesses before they become security threats.
We engineered a secure architecture that systematically eliminated the vulnerabilities of the previous infrastructure and protected sensitive customer billing information. To maintain peak security, our team established continuous audits and automated patch management to keep the system fully aligned with telecommunications compliance standards.
Training and change management for seamless adoption
Softweb Solutions delivered targeted training and change management programs to accelerate internal adoption. Our team enabled employees to master updated workflows within weeks after the initial go live.
We empowered support teams with real-time customer data to resolve billing inquiries in half the time. This immediate access to accurate information removed common problems across everyday customer service operations.
Continuous monitoring and optimization for lasting accuracy
We set up automated monitoring across the billing platform to track performance, errors, and usage patterns around the clock. Dashboards alert the operations team the moment anomalies or processing delays appear anywhere in the system. Regular feedback cycles with the client’s team guide ongoing refinements to the platform.
Softweb Solutions engineered a continuous verification loop to maintain high billing accuracy as products expand. Our system helps the client catch potential errors before they ever reach customer invoices. In addition, these automated cycles provide clear data to guide future platform enhancements.
