What it is

Quo is a paid business phone service with web, Windows, macOS, iOS and Android support. It offers desktop and mobile apps, multiple business numbers, an auto attendant, custom call routing and voicemail transcription. Quo has no free plan, but a seven-day trial is listed. Its pricing note gives a starting rate of $15/user/mo on an annual term. Separately, monthly plan listings show Starter at $19 a month, Business at $33 a month and Scale at $47 a month. Each of those monthly listings includes one phone number per user and 1,000 free automation credits. The annual starting-price note and monthly plan figures are distinct details, so readers should check which billing term applies to their choice. With support for five listed platforms and both mobile and desktop apps, Quo provides business calling across a range of devices. Its call-handling options include routing calls and directing callers through an auto attendant.
