Telecom
Subscriber management, telecom billing, network monitoring, customer self-service.
How we work in telecom
RNDSOL is a telecom software development company building subscriber management, billing engines, and self-service portals for ISPs, MVNOs, and operators. Telecom software is where scale gets serious: millions of subscribers, billions of usage records, and billing runs where a rounding error becomes a regulatory complaint. We build BSS/OSS software that treats accuracy at volume as the core requirement, because in this industry it is.
Our telecom work covers subscriber management and provisioning, rating and billing engines that process usage records in the hundreds of millions per day, and self-service portals that keep routine requests out of the call centre. We work from Lahore, Pakistan, a city with deep telecom engineering talent thanks to the operators and vendors based here, and we've delivered for connectivity businesses in the Gulf.
We're realistic about where custom development fits. Tier-one operators run commercial BSS stacks, and we integrate with those rather than compete. Where we shine is the layer around them: ISPs and MVNOs needing full-stack billing, operators needing a portal or partner API their vendor quotes eighteen months for, and niche services the big suites don't model.
What we build
The problems that bring teams to us
These are the patterns we see most often in telecom engagements, and how we handle them.
Billing accuracy at volume
Rating millions of CDRs daily leaves no room for drift. We build rating pipelines with idempotent processing, replay capability, and revenue assurance reports that catch discrepancies the same day they occur.
Provisioning across systems
Activating one subscriber can touch half a dozen network and IT systems. We build orchestration with automatic rollback, so a failure halfway leaves a clean state instead of a stuck order the call centre discovers.
Call centre deflection
Balance checks, package changes, and bill queries shouldn't need a human. Well-built self-service portals routinely absorb the majority of these interactions, and we design them around the top call drivers in your actual ticket data.
Legacy BSS constraints
Old billing systems resist change, and every product launch waits on them. We build modern API layers over legacy cores, so new products and partner integrations ship in weeks without a rip-and-replace.
Offer launches measured in quarters
When every new bundle needs billing changes, marketing queues behind IT. We build catalog-driven product models, aligned with TM Forum SID where it helps, so a new plan or promotion is configuration the rating engine picks up, not a code release with a test cycle.
Digital-first subscriber journeys
Subscribers now expect to join, top up, and switch plans from an app without visiting a shop. We build digital BSS layers covering online signup, eKYC where the regulator requires it, and eSIM activation flows through your SM-DP+ provider's APIs.
How a project runs
Start from the revenue chain
Usage capture, mediation, rating, invoicing, collection: we audit the whole chain first, because a billing project that only looks at the invoice misses where the money leaks.
TM Forum-informed design
We align data models and APIs with TM Forum Open API patterns where it helps interoperability, without turning your mid-size operation into an enterprise architecture project.
Shadow-run before cutover
New billing runs in parallel with old for at least one full cycle, and every invoice is compared line by line. Cutover happens when the diff report is empty, not when the calendar says so.
Monitor what customers feel
Network dashboards track what engineers care about; we add monitoring for what subscribers experience, activation time, failed top-ups, portal errors, and alert on those too.
Built to the rules your sector runs on
Standards and regulations we design against in this industry. Your compliance team owns interpretation; our job is making the system enforce it.
Questions we hear from teams like yours
Yes, that's our sweet spot in telecom: rating, invoicing, payments, dunning, and subscriber self-care for operations between a few thousand and a few million subscribers, where commercial BSS suites are overkill and spreadsheets have long since collapsed.
Parallel runs. The new system rates the same usage as the old one for at least a full billing cycle, and we reconcile every invoice line before cutover. It's slower than a hard switch and it's the only method we trust with revenue.
We do, through whatever the equipment offers: RADIUS, SNMP, vendor APIs, or CLI automation where nothing better exists. Provisioning orchestration with rollback is usually the first module we build because everything else depends on clean activations.
Our pipelines are built on streaming architectures designed for hundreds of millions of records per day, with backpressure handling and replay. We load-test against your peak volumes plus headroom before anything goes live.
Yes. We build catalog-driven product models where a new plan is configuration rather than a release, and activation flows that provision eSIM profiles through your SM-DP+ provider's APIs. For an MVNO going digital-only, that signup-to-activation path effectively is the product, so we treat it as the first milestone.
