Telecom & Communications
Billing, provisioning and customer apps that keep pace with your network.
EIT Connect is a telecom software development company for ISPs, fibre broadband operators, VoIP and cloud telephony providers, and virtual network operators. We build and modernise the systems that sit between your network and your revenue: OSS/BSS platforms, billing and charging, provisioning, customer self-care apps and the integrations that hold them together.
Most telecom teams we speak with don't need a new platform for its own sake. They need a plan change to reach the network without three manual steps, invoices that match actual usage, and fewer support calls that open with "my bill is wrong." That is the work our custom telecom software development is built around.
What We Build
Our telecom software development services focus on the layer that slows most providers down: the business and operations software around the network. You can start with the one module that hurts most, or plan a phased replacement of the whole stack.
BSS runs the commercial side of a telecom business: product catalogue, orders, customers, billing and collections. OSS runs the operational side: inventory, provisioning, service assurance and fault management. Our OSS BSS software development connects the two, so an order placed in the CRM provisions the service, starts billing and appears in the customer's app without anyone re-keying it. We build new modules, extend the platform you already run, or replace the parts holding everything else back.
Billing is where telecom revenue quietly leaks. Our telecom billing software development covers rating and charging for prepaid and postpaid plans, usage mediation from CDRs and session records, bundles and discounts, proration when a customer changes plan mid-cycle, GST-ready invoicing, payment collection and dunning. We also build reconciliation reports that compare what the network delivered with what was billed. That comparison is usually where the first quick win shows up.
For cloud telephony, contact-centre and CPaaS providers, our VoIP software development covers customer and reseller portals, number and DID management, IVR and call-flow builders, call recording, analytics dashboards, browser calling over WebRTC and softphone apps. We connect to the softswitch or PBX you already run instead of asking you to replace it.
Many regional ISPs still run on a mix of spreadsheets, a RADIUS server and payment links sent over WhatsApp. We build subscriber management platforms that handle plan catalogues, activation and suspension through your RADIUS/AAA setup, data-usage and fair-usage tracking, renewals and auto-collections, franchise and partner logins, and new-connection workflows from enquiry to installation.
Ticketing, NOC dashboards, alarm views, network inventory and field-force tools for installations, fault repairs and site maintenance. Technicians see the job, location, equipment list and customer history on their phone. Supervisors see SLA timers before a breach, not after it.
Plenty of telecom systems built ten years ago still work, just slowly and expensively. Through application modernization, we move one domain at a time from the old monolith to services you can change without fear, and shift workloads to the cloud where the numbers make sense. Our application integration team then connects CRM, ERP, payment gateways, SMS gateways and network systems, so customer and usage data lives in one place instead of five.
Churn prediction, usage forecasting, revenue assurance alerts and fraud patterns, built on data you already collect: CDRs, tickets, payments and app events. Our data analytics and AI development teams turn that data into dashboards and alerts your commercial and network teams will actually open.
Apps
Customers judge a provider by its app, not its network diagram. Our telecom app development team builds Android, iOS and cross-platform apps on the same billing and provisioning backend, so what the customer sees always matches what your systems know. Platform choices and our approach are covered on the mobile app development page.
Typical features:
Job assignment, navigation, offline forms, photo proof, customer sign-off, equipment scanning and on-site activation. Built to keep working in basements and rural areas where the signal drops halfway through a job.
For distributors, franchisees and local partners: onboarding, new activations, commissions, wallets and stock, with every transaction visible in your back office.
Who We Serve
Tier-1 carriers usually buy from a handful of global BSS vendors. We work with the businesses around them: providers big enough to feel the cost of manual operations, but too specialised for an off-the-shelf suite to fit without heavy workarounds.
Subscriber management, RADIUS integration, installation workflows and self-care apps that cut support calls during outages and renewals.
Customer and reseller portals, usage-based billing and developer-facing APIs. Many of these providers run as subscription businesses, so our work on SaaS software solutions applies here as well.
A lean BSS layer (plans, rating, billing, self-care) on top of a host network, built so you can launch new plans in days rather than waiting on a vendor change request.
SIM lifecycle management, usage pooling and connectivity dashboards for B2B customers. For the device and platform side, see our IoT software solutions.
Site inventory, maintenance scheduling, fuel and energy logs, and field-force apps that bring every site's status into one view.
Line inventory, invoice audits and cost allocation for companies with hundreds of connections across locations and carriers.
Challenges
Every telecom software project we take on starts with a business problem, not a feature list. These are the ones we see most often.
Usage delivered but never rated; promotional discounts that never expire
What we build Usage reconciliation and revenue assurance reports
Orders re-typed across CRM, RADIUS and billing; customers wait days
What we build Order-to-activation workflows with API-based provisioning
Customers leave after one wrong bill or one slow ticket
What we build Self-care apps, proactive outage alerts and churn scoring
Every small change needs the original vendor and a change request
What we build Phased modernisation behind stable APIs
Data, SMS and security rules change faster than the software
What we build Consent records, audit trails and configurable retention
Month-end bill runs and recharge spikes slow everything down
What we build Queue-based processing and auto-scaling cloud setup
Build or Buy
Buying a ready platform is sometimes the right call. Here is how the two options usually compare.
| Factor | Off-the-shelf telecom platform | Custom telecom software |
|---|---|---|
| Best fit | Standard plans and processes; speed matters most | Unusual plans, bundles, partner models or legacy systems to connect |
| Time to launch | Faster for standard setups | Longer upfront; phased releases reduce the wait |
| Upfront cost | Lower | Higher |
| Ongoing cost | Licence or per-subscriber fees that grow with you | Hosting and support; no per-subscriber licence |
| Fit with your processes | You adapt to the product | The software adapts to you |
| Integration | Limited to the connectors the vendor offers | Built around your network, CRM, ERP and payment systems |
| Ownership | Vendor owns the roadmap | You own the code and the data |
A hybrid approach is common and often sensible: keep a proven billing core, and build custom portals, apps and integrations around it. During discovery we will tell you plainly which route fits your situation.
Compliance
Telecom systems hold identity details, location data, call records and payment information, so security can't be added at the end. Our DevSecOps practice builds code scanning, secrets management and role-based access into the pipeline from the first sprint. For Indian operators, we design around the requirements your compliance team already tracks, such as:
Consent records, purpose limits, and handling of access and deletion requests
DLT-registered headers and templates for transactional and promotional SMS
Log retention and incident reporting timelines
Compliant tax invoices, with e-invoicing for B2B customers where it applies
Record and CDR retention as set out in your licence
We build the controls and audit trails; your compliance team confirms which obligations apply to your licence category.
Technologies
Telecom workloads mix real-time traffic, heavy batch jobs and customer-facing apps, so we choose the stack per component, not per project.
PostgreSQL
MongoDB
AWS
Google Cloud
Systems we integrate with: RADIUS/AAA servers, SIP and WebRTC platforms, softswitch and PBX APIs, DLT-compliant SMS gateways, UPI and card payment gateways, CRM and ERP systems. Partners and new apps connect through documented REST APIs built by our API development team.
When orders flow from CRM to network to billing automatically, new connections go live the same day, not after a chain of emails.
Rating rules that match your actual plans, plus usage reconciliation, mean fewer wrong bills and fewer support calls about them.
Launching a plan, a bundle or a partner programme becomes a configuration task, not a vendor project with its own invoice.
Usage, churn and revenue sit in one model, so commercial and network teams finally work from the same numbers.
How We Work
Telecom software development carries one risk most projects don't: if billing breaks, revenue stops. Our process is built around that.
We map every system an order touches and mark where data is re-keyed, delayed or lost.
We decide what to keep, extend or replace, design the data model, and set security and retention rules up front.
New connection, plan change and bill dispute flows, clicked through by your operations and support staff before any build starts.
Regular demos, with integrations built against supplier sandboxes early, not in the final month.
Load tests at peak volumes, and parallel bill runs that compare old and new invoices line by line before switch-over. Our software testing team owns this stage.
Subscribers move in batches, with a rollback plan for each one.
Monitoring, fixes and new features under our software maintenance and support plans.
Why EIT Connect
We won't pitch a rip-and-replace when a well-built integration solves the problem. Discovery tells us which one you need.
Backend engineers, mobile developers, UI/UX designers, testers and DevOps work as one team, so the app, the portal and the billing engine never disagree about a customer.
No per-subscriber licence and no lock-in. The source code, documentation and subscriber data are yours from day one.
Sprint demos, a shared roadmap and one point of contact. You always know what's built, what's next and what it costs.
Telecom software development is building the software that telecom providers use to sell, deliver, bill and support their services. It covers OSS/BSS platforms, billing and charging systems, provisioning, customer self-care apps, VoIP platforms and the integrations that connect them to the network.
BSS (business support systems) handles the commercial side: products, orders, customers, billing and payments. OSS (operations support systems) handles the network side: inventory, provisioning, monitoring and fault management. Most problems appear where the two don't share data, which is why we build them to work as one flow.
Cost depends on scope: the number of modules, how many systems need integrating, subscriber volumes, apps and compliance needs. A single module, such as a self-care portal or a billing integration, costs far less than a full OSS/BSS replacement. We share a fixed estimate after a short discovery call.
A focused module or app usually takes a few months. Replacing a full OSS/BSS stack is a phased programme over several releases, because subscribers and billing move in batches with parallel testing. You get a timeline for your scope after discovery.
Yes. Most of our telecom work connects to systems already in place. We integrate through their APIs or databases, and where an old system has no API, we build a safe integration layer around it rather than forcing a replacement.
Yes. Our telecom app development covers subscriber self-care apps, field technician apps and partner or reseller apps for Android, iOS and cross-platform, all connected to the same backend as your billing and provisioning.
Yes. We build customer and reseller portals, number management, IVR and call-flow tools, call analytics, WebRTC calling and softphone apps that work with your existing softswitch or PBX.
Buy if your plans and processes are standard and speed matters most. Build if you have unusual bundles, partner models or legacy systems to connect, or if per-subscriber licence fees are growing faster than revenue. A hybrid, with a ready billing core and custom portals, apps and integrations, often works best.
Look for a team that asks about your network, billing and compliance in the first call, can show integration work similar to yours, tests billing with parallel runs before switch-over, and hands you full code ownership with post-launch support. Ask us the same questions; we're happy to answer them.
Tell us what's slowing you down: manual activations, billing disputes, a legacy platform nobody wants to touch, or an app customers avoid. We'll map the systems involved, recommend whether to integrate, extend or rebuild, and give you a phased plan with clear costs.
