- Linear Per-Seat Scaling (5 Seats × $15/seat/mo): Base license scales linearly with operator headcount ($75/mo for 5 seats on Pro).
- Primary Operational Bottleneck: Primary Operational Trade-Off: In practical enterprise deployments, the primary trade-off is that the $0 Free tier limits meeting and recording history to 30 days with capped automations, requiring sales teams to subscribe to the $15/user/month Pro tier or above for unlimited meeting history and full CRM integration workflows.

- Sales-Gated Contract Terms: Pricing available on request.
- Primary Operational Bottleneck: Primary Operational Trade-Off: In practical enterprise deployments, the primary trade-off is that Opine is architected specifically for complex, consultative B2B sales motions involving technical evaluations or POCs, making its deep presales workflows unnecessary for high-velocity, one-call transactional SMB sales.
Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Opine requires sales-gated custom quoting).
