TRUSTED BY TEAMS
Telecommunications software development is rarely a blank page. Most telecom businesses already run billing, CRM, OSS and network systems from several vendors, and the work is building what is missing and connecting it to what exists — without disrupting a single customer or bill.
Sodio provides custom telecom software development services for regional operators, ISPs, MVNOs, CPaaS and VoIP providers, and enterprises with large telecom estates, from a first integration to a full platform.
/// IS CUSTOM RIGHT FOR YOU?
Buy First. Build Where It Pays.
The best telecom software decision is often to buy. Mature products exist for billing, CRM, monitoring and most of the OSS/BSS stack, and a custom build that recreates one of them is money spent twice. Custom telecom software development earns its place in four situations.

/// COST AND TIMELINE
What Drives the Cost and Timeline
A first working piece, built against your real systems and data, typically arrives within 30 days, with a production build in 90. Larger programmes are delivered in phases after that, each one live before the next begins.
The cost moves with six things: how many existing systems are involved; data and usage volumes; how much legacy data has to move; the regulatory and partner certifications required; the testing needed, especially where billing is affected; and whether the software serves your own business or is a product you sell.

Frequently Asked Questions
It builds and integrates the software telecom businesses run on — billing and CRM, OSS/BSS, network monitoring, communications products such as CPaaS and VoIP, analytics and AI. In practice, much of the work is connecting new software to the systems an operator already has, and changing them without disrupting customers or bills.
Mainly regional operators, ISPs and fibre networks, MVNOs and MVNEs, CPaaS and VoIP providers, and enterprises managing large telecom estates. We work with larger operators on specific systems that sit alongside their core platforms rather than replacing them.
Yes. We start with a review of the code, architecture and integrations to understand what exists, what is worth keeping and what is holding the business back, then recommend whether to extend, refactor or replace it — and say so if it is sound.
Carefully, and with your compliance team. Number porting, emergency calling, customer data protection such as CPNI and GDPR, and telecom taxes all have rules that vary by country. We build the controls into the software, test them against the formats regulators and partners require, and work with your advisers on what applies.
Ownership is set out in the contract before work starts. As standard, the software we build for you belongs to you, and we do not build on a proprietary framework that ties you to us.
Support, monitoring and regular releases continue as long as you need them. Every release goes through automated regression testing across the systems it touches, and releases are timed around your billing cycles — never on the day a bill run is due.
