What Sonar is

Sonar is a web and API platform for broadband internet service providers. It brings billing, customer accounts, network operations, field dispatch, and inventory into one system. Sonar says it is mainly built for Tier 2 and Tier 3 operators serving 5,000 to 75,000 subscribers across fiber, WISP, cable, MDU, and VoIP networks. Billing tools cover recurring charges, contract management, a customer portal, refunds, reversals, and VoIP billing; sonarPay is an optional payment-processing add-on for the United States and Canada. Field operations include scheduling, dispatch, GPS tracking, and a mobile technician app. Network functions provide monitoring, alerts, reports, fault diagnostics, device provisioning, and performance tracking. Looker reports cover financial and tax data, churn insights, and forecasting. The GraphQL API supports integrations and automation, with webhook guidance and a schema explorer. Sonar also lists integrations, paid custom work, migration assistance, training, and North America-based weekday support. Pricing starts at $500/month with a contract and varies by active subscribers.
