Video conferencing for cross-border client calls

Video conferencing for cross-border client work mostly comes down to which platform the client already uses and trusts, more than any technical difference between the three main options at this scale.

Google Meet integrates directly with Google Calendar and needs no download for a guest to join from a browser, which lowers friction for a first call with a client unfamiliar with the tool, and is what this site's own booking flow through Cal.com defaults to. Zoom has the widest name recognition globally and the most reliable performance on lower-bandwidth connections, a real factor for calls into markets where connection quality varies, at a cost once a call needs to run past the 40-minute free-tier limit on group calls. Microsoft Teams makes the most sense when a client already runs their internal operations through Microsoft 365, since scheduling and file-sharing tie in directly with tools they're already using.

A first call with a new client is usually smoothest on whichever platform requires the least setup on their end, Google Meet or Zoom's guest link, both join from a browser. Teams is worth defaulting to specifically when the client's own organization already runs on Microsoft 365.
