An operator's billing core is rarely rewritten from scratch — it has carried tariffing, partner settlements and millions of daily transactions for years. At the same time subscribers expect a self-service portal and mobile app on the level of banking services. SOWA Digital reinforces operators' IT teams with engineers equally confident with legacy billing and the modern self-service layer on top of it — without taking the network down and without a big-bang release in production.
Four areas where we most often reinforce telecom teams or take development on entirely — from billing to subscriber base analytics.
Real-time tariffing, partner settlements and roaming require a fault-tolerant core, not a set of scripts around an ageing database. We design and extend billing with predictable peak-hour load in mind and calculations without the rounding that eats into revenue.
Web and mobile self-service — balance, tariffs, service activation, support requests — takes part of the load off the call centre and retail. We design the portal as a separate product with its own release cycle, not tied to the pace of change in the billing core.
We connect billing, CRM and subscriber services to the operator's network layer — from traffic accounting systems to adjacent elements of the OSS/BSS landscape. We work through resilient APIs and message queues so that a failure in one component does not stop tariffing in all the others.
We build reporting and dashboards on traffic consumption, ARPU, subscriber churn and tariff plan performance. Data is collected from billing and network systems into a single warehouse available to commercial and technical teams without manual exports.
Billing and network integrations do not forgive experiments in production. We work so that resilience and uninterrupted subscriber service are part of the architecture, not the aftermath of an incident.
For billing, degradation is not a bug but direct revenue loss and subscriber complaints. We build in redundancy, monitoring and alerting at the architecture stage, not after the first incident.
We replace legacy components piece by piece — through parallel runs and gradual traffic switchover, not a single cutover. Subscribers should not notice that the tariffing code is changing behind the scenes.
We put billing and the self-service API through load tests close to the operator's peak hours before release — rather than hoping production will somehow cope.
We work to ISO 27001 and sign an NDA from first contact. Engineers' access to production subscriber data and billing systems is limited by role and recorded in the audit trail.
These are not the terms of a specific contract but the frame we start from — actual figures depend on the operator's scale and the state of the current infrastructure.
Yes. We start with an audit of the current billing — platform, version, integration points — and propose integration through APIs or message queues wherever possible, instead of rewriting the core from scratch. A full platform replacement is discussed separately and only if it is justified by accumulated technical debt.
We design for peak load rather than average: horizontal scaling, queues to smooth out spikes, and load testing before every release of billing-critical components. Monitoring and alerting are set up before going to production, not after.
Yes, this is the most common format in telecom — reinforcing the operator's in-house team with developers experienced in billing, self-service or network integrations, without outsourcing the whole project. More about the format on the IT Outstaffing page.
On average 14 days from agreeing requirements to engineers joining the project — thanks to a pool of 50+ specialists already vetted for experience and under NDA.
Describe the situation with your current billing or self-service — we will propose a format: targeted team reinforcement or an end-to-end outsourced project. Similar cases are in our portfolio.
