Telecom stacks span decades
A modern carrier runs 5G core alongside 15-year-old billing systems, talking to 30-year-old ordering flows. QA in this environment is less about a single app and more about making sure a change over here doesn't break something four systems away.
What we test
BSS: Order-to-Cash
CRM, ordering, provisioning, activation, billing, dunning. End-to-end flow verification.
OSS: Service Assurance
Inventory, fault management, performance monitoring, service-level reporting.
Billing & Revenue Assurance
Rating, mediation, invoicing, revenue recognition. Zero-drift reconciliation.
Number Portability
LNP flows, NPAC integration, port-in / port-out state machines.
Self-Service & App
Customer web + mobile app: plan changes, add-a-line, device upgrades, bill-pay.
5G Core / Network APIs
CAMARA APIs, network slicing exposure, quality-on-demand flows.
Approaches that work in telecom
- State-machine testing — every telecom flow is a state machine; test it as one
- Contract testing across BSS/OSS boundaries where interfaces don't change often but breakage is catastrophic
- Synthetic subscriber lifecycles — create, provision, use, upgrade, cancel — as a single automated flow
- Reconciliation harnesses — nightly checks that billing matches usage matches provisioning
Who we've helped
- MVNOs launching on new host networks
- Regional carriers migrating BSS platforms
- InfraCos exposing 5G APIs to enterprise buyers
- Wholesale telecom running number portability at scale
