What Is An Inside Sales Representative?

An inside sales representative (ISR) sells remotely by phone, email, and video, taking leads from first conversation to signed deal without travel. At SaaS companies, that means following up on inbound leads, running product demos, handling objections, and closing smaller deals. The role is commonly nearshored from Latin America for time zone compatibility.

Bogota, Mexico City, Sao Paulo, and Buenos Aires don’t change their clocks, so the overlap shifts when yours does. Times shown are in your team’s time zone. National English-proficiency averages vary by market too: Argentina ranks in EF’s "High" band globally, while Colombia, Mexico, and Brazil sit in the "Low" band. Screen every candidate’s spoken English directly rather than assuming by country.

Common mistake: hiring an SDR profile into an inside sales seat. SDRs are built for outbound prospecting and booking meetings, and they typically do not close deals. An inside sales rep is expected to run demos and close, so screen for discovery, objection handling, and a closed-won track record, not only call volume.
