Sonar review

Sonar is the closest rival to Splynx, with a stronger focus on North American broadband. Its pricing page bills by active subscriber, not by seat or module, starting at $500 per month on an annual contract and stepping down from $1.25 to $0.75 per subscriber as you pass 5,000 and 10,000 accounts. The included platform covers accounts, billing, ticketing and CRM, a self-service portal, outbound SMS, job scheduling with GPS for field teams, inventory with purchase orders, and network monitoring with device provisioning. Financial reports come through Looker, and the billing side handles refunds, reversals and churn forecasting. Premium items such as sonarPay payment processing cost extra. Compared with Splynx, the entry cost is higher and the per-subscriber rate is above Splynx's first band, but Sonar stresses in-house North American support and experience with operator mergers. It suits fiber and wireless ISPs in the US and Canada more than mobile resellers elsewhere.
