The savings are the seats you do not buy

Onyx Phone charges $29 for the account. Quo and RingCentral charge for each person. These are their published month-to-month list prices in 2026, not a quote from those companies. Annual prepay is lower on both of them: Quo Starter $15 per person, RingCentral Core $20 per person.

One person

Quo Starter at $19 is less than Desk, and that plan includes US texting. RingCentral Core at $30 is about the same as Desk. A solo user who needs texting should not pick Onyx Phone to save money.

Three people

Quo is $28 more each month, about $336 a year. RingCentral is $61 more each month, about $732 a year. Those gaps are the seat fees. They are not a claim that the products match.

Five people

Quo is $66 more each month. RingCentral is $121 more each month. Desk stays $29 as long as one number is enough.
