Telecom software development services for the systems around your network

A telecom software development company for carriers, ISPs, and the companies that sell them software

Telecommunications software development at Devrisen starts from what an operator already runs. A carrier or ISP keeps its vendor platform for billing and network operations and needs new software built beside that platform: the portal customers use, the path from an order to a working service, the inventory that says what is available, and the app a technician opens on site. A company that sells software to operators needs the same systems as a product many of them can adopt, with clean integrations and roles designed for customers it has not met. That product's telecom side gets the same team and process as an operator's build.

Some telecom software is not ours to build, and saying so early saves everyone time. Radio and core network functions, 5G core included, and the billing engines that rate every call, session and message belong to specialist vendors. The software we build reads bills from the billing system, sends plan changes through order management, and leaves those systems in place.

Where a telecom order breaks between systems

Scoping follows one of your orders from sale to working service, because the trouble tends to sit in the handoffs, where no single team is watching. Each break traces back to a decision nobody made.

Where the order is	What goes wrong	What scoping settles
Sales hands it to operations	It is entered in the CRM, re-keyed into order management, and never reaches network inventory	Which system owns the order at each step
A port or pair is assigned	The inventory shows it available, and the technician finds it occupied	Whether provisioning updates the inventory itself or leaves that to someone afterwards
The customer asks for a change	The portal shows the plan but cannot change it, so the request becomes a call center ticket	Whether the portal acts through the same services the care agents use
The technician is on site	The work order changed after dispatch, and the app heard about it late or never	How the field app learns of a change, including where there is no signal

Telecom software solutions we build

We build five kinds of system, each at a point where customers, orders or field crews meet an operator's systems.

Anything next to these gets the same questions: the roles the system serves, the records it owns, and the platforms it has to reach.

Fitting the platforms a carrier already runs

The operator's OSS/BSS platform stays, whether it comes from a suite vendor such as Amdocs, Netcracker or CSG, a smaller vendor, or was built in-house, and the new software is built to connect to it. Where the platform exposes APIs, we build against them, including TM Forum Open APIs when it offers them. Where it only produces file exports, the connection runs on a schedule and every run is logged.

Around that platform an operator usually runs a CRM, an ERP and often a messaging API, and we have integrated all three before, for clients outside telecom. On the CRM side that means Salesforce, Microsoft Dynamics 365, HubSpot, Zoho CRM and Pipedrive; for ERP, SAP, Oracle NetSuite, Odoo and Dynamics 365. Messages have gone out in production through Twilio, Vonage, Bird and Plivo.

Our guide to which records a telecom CRM should own covers where it hands off to billing and order management.

Before any code is written, every connection is documented, with one owning system for each record. Two of the breaks above, the re-keyed order and the untrusted inventory, start where that question was left open.

Changing live telecom systems in phases

We replace a live telecom system in pieces. The new system runs beside the old one, kept in sync, while customers move across in groups. Each group's back-out plan covers its cut-over window, and after that, problems are fixed forward. Cut-overs land in the change windows the operator's change board sets, when fewer customers are affected.

Our engineers have carried out modernization and migration work on production systems before. DevOps owns the environments and each release, monitoring is live before the first group moves, and the team that planned the migration runs it. A group that moves cleanly clears the way for the next. A group that hits trouble inside its window moves back, and the cause gets fixed before it moves again.

How a telecom build runs

A telecom build moves through five steps, and the people who scope the system are the people who build it.

For longer-term telecom software outsourcing, where one team carries several systems over time, a dedicated team on a fixed monthly fee is the better fit.

We take on telecom builds for operators and telecom software companies across the US and Canada, the UK and Europe, the Middle East, and Australia and New Zealand. We keep a daily working overlap with the UK and Europe, the Middle East, Australia and New Zealand, and the US East Coast. For client meetings, we overlap with all of Canada.

The stack for a telecom build

Each technology below is one the team specializes in, matched to the part of the system it serves.

• Customer portals and agent tools — React, Next.js, Angular, TypeScript
• Integration services and APIs — Node.js, NestJS, Java, .NET, Laravel on PHP
• Operational records — PostgreSQL
• Hosting — AWS
• Self-care and field apps — Flutter, React Native

Every contract assigns the code and the intellectual property to the client: the code lives in the client's own repository, and production runs in cloud accounts the client owns, with monitoring switched on from launch.

What telecom software development costs

Five things set the price of a telecom build, and scoping measures each one before a number is written down:

• Systems of record — how many the software has to connect to.
• The vendor platform — whether it offers usable APIs or only file exports, and what API access it licenses.
• Channels — the customer portal, the agent tool, the field app, or all of them.
• Data — how much inventory or customer data needs reconciling and migrating first.
• Voice and messaging — how many flows and providers it needs, since each provider integration is its own piece of work.

The first scoping call is free. The short paid assessment that follows produces the fixed quote, itemized so any part can be cut deliberately. To start, describe the systems the build has to connect to.

Custom telecommunications software solutions or a vendor platform?

Buy when the process belongs to the vendor. Off-the-shelf telecommunications software handles standard billing, rating and network operations well, and rebuilding that rarely pays for itself. Extend when the platform is right and one gap is not, such as a portal customers will actually use or an order flow that ends the re-keying. Build when the workflow is the operator's own, or when the software is the business.

Scoping says which answer applies before anything is quoted, and sometimes the answer is to buy. When the job turns out to be something else, it is a different service. If you sell software to operators, the multi-tenant side of that product, where many operators share one platform, is covered under SaaS development. Where the system is internal and spans departments, treat it as an enterprise build. Testing a first version with real customers starts with a minimum viable product, and a live system that needs looking after can go onto a maintenance retainer.

Related systems, already built for other industries

Several systems an operator runs on are ones we have already built, for clients in other industries: inventory and stock systems (the shape of an operator's equipment and spares stock, not its network inventory), customer self-service portals, and field and mobile workforce apps.

We have also delivered every CRM, ERP and messaging integration named above. That integration work is the part that transfers most directly, because keeping records in step across systems is the same engineering problem wherever the records live.

Telecom adds strict change control on top, which is what the phased approach above is for. A plant floor asks the same of us for the same reason, which is why manufacturing software solutions are built the same way. Meet the engineers who would work on a telecom build.
