What is an Inside Sales Agent (ISA)?
An Inside Sales Agent (ISA) is a sales professional who qualifies leads, nurtures prospects, and books appointments from a remote or office-based location. ISAs are most common in real estate and home services, where they feed qualified appointments to producing agents or sales reps.
In more detail
In real estate, ISAs call internet leads, FSBOs, expireds, and past clients to nurture them into buyer or seller consultations. They are usually measured on contact rate, appointment-set rate, and appointments held. Strong ISAs can produce 50+ appointments per month and directly drive agent production.
ISAs earn a base plus bonus per appointment or per closed deal. US-based ISAs typically earn $45,000-$75,000 OTE. Offshore ISAs through managed providers usually run $1,500-$3,000 per month all-in and staff in US time zones with native-accent voice training.
What an ISA does
- Call and qualify new leads within minutes of assignment.
- Long-term nurture of leads that are not ready now.
- Book appointments directly on agent calendars.
- Follow scripts while adapting to lead objections.
- Update the CRM with every interaction.
