The story
Sonar has focused exclusively on OSS/BSS for broadband ISPs (fiber, WISP, cable, MDU, VoIP) since 2015. The company's embedded finance angle emerged with the launch of sonarPay — an integrated payment processing product for ISPs — which repositions Sonar from pure billing software toward being a payments-and-ops platform. sonarPay now runs alongside the legacy option to plug in third-party card processors (Stripe, Bambora, Moneris, Authorize.net, CardConnect, etc.) via Sonar's schema.
