Google Voice vs. Quo

Google Voice is Google's business phone add-on for Workspace, built into Gmail, Calendar and Meet. Quo, formerly OpenPhone, is an app-only phone system for small teams with strong texting, AI and outside integrations. The core difference: Google Voice fits companies already on Workspace, Quo fits teams that live in a CRM.
