ProfessionalOur pick $79/seat/mo billed yearly Full-time reps. | Add-ons (Engage, Forecast, Enable) Custom Teams that want outreach, forecasting or coaching in Gong too. | Suite ProfessionalOur pick $115/agent/mo billed yearly, or $149 monthly Growing support teams that need skills-based routing and better AI tools. | |

| Which plan to pick | Start on Free to check the data covers your market. Basic suits one person prospecting; Professional is worth it if you also call prospects or want AI scoring. Monthly billing costs noticeably more than the yearly prices shown. | Start with the core licence for reps who run customer calls and add Forecast or Engage only once the team uses Gong daily. Push back on bundles and multi-year terms during negotiation. | Support Team only makes sense for email-only teams. Most businesses wanting AI and live chat should trial Suite Professional (the trial includes Copilot), then work out how many AI resolutions they will use, because extra resolutions at about $2 each can cost more than the seats. |
