Sonar alternative for internet providers The same system of record. Plus the people-work, done.
Inerxia is a Sonar alternative for US internet providers: billing with sales tax, USF and E911, provisioning, ticketing and inventory on one subscriber record — plus AI agents that resolve inbound calls and texts, payment reminders with your own payment links, and QA on every call.

Being fair
Where Sonar is stronger.
Sonar is a strong system of record, and sonarPay is a genuinely good embedded processor. It has deeper US grant and BEAD reporting tooling and a larger published North American installed base. If those are your constraint, Sonar may be the better call.

- AI agent answers inbound voice end to end
- AI agent resolves inbound text and chat
- Escalation to a human with full context
- Churn scoring with proactive intervention
- Managed operation billed on outcomesNot seats, not hours
- Transcription of every call
- QA score on 100% of calls
- Issue clustering and root cause from transcripts
- Detection of issues raised on calls that never became tickets

Switching
Moving from Sonar without stopping the operation.
You do not have to migrate on day one. Most operators start alongside their current system and move the record last.
- 1.
Start with Intelligence
Keep Sonar as your system of record. Intelligence reads the calls and tickets it already generates and hands back clusters, QA scores and the faults nobody mapped.
- 2.
Add agents to the queue
Point inbound voice and SMS at the agents for the repetitive cases only, and measure the deflection against your own numbers.
- 3.
Automate collections
Let the collections agent send reminders and your existing payment links for one cycle, and compare the collection curve before deciding anything.
- 4.
Then migrate the record
Subscribers, contracts, balances and equipment are migrated and verified, then a full cycle runs in parallel. Four weeks to your first cycle; migration, training and support included.
Switching from Sonar.
Is Inerxia a Sonar alternative?
Yes. Inerxia covers the system of record Sonar provides — billing with sales tax, USF and E911, subscriber and contract records, ticketing, inventory, and RADIUS, TR-069 and OLT/GPON provisioning — and adds AI agents that resolve inbound calls and texts, payment reminders with your own payment links, and QA on every call.
What does Sonar do better than Inerxia?
Sonar has deeper US grant and BEAD reporting tooling, a larger published North American installed base (Sonar publishes 385+ providers), fuller IPAM and network monitoring, and a published M&A consolidation playbook. Operators whose main need is BEAD reporting may be better served by Sonar.
Can we keep Sonar and still use Inerxia?
Yes. Most operators start with Subscriber Intelligence reading the calls and tickets their current system already produces, then add AI agents to the queue for repetitive cases. Sonar stays the system of record until, and unless, you decide to migrate.
How long does it take to migrate from Sonar?
Four weeks to your first full billing cycle in Inerxia. Subscribers, contracts, balances and equipment are migrated and verified against your live base, then one cycle runs in parallel with Sonar; nothing cuts over until it matches. Migration, training and support are included.
Do we have to give up sonarPay?
No. Inerxia does not process payments. It works with the processor you already use: reminders and collections messages carry your existing payment links, and confirmed payments reconcile against the invoice and restore service automatically.
Bring your Sonar setup. We will map it for you.
Thirty minutes, your own numbers, and a straight answer about where Inerxia fits. If Sonar is the better call for your situation, we will tell you on the call rather than after the implementation.
