|---|---|---|
| Category | Communications & APIs | Customer Support & CX |
| Pricing Unit | per US Outbound SMS Segment (+ Carrier Fees) | per Agent / mo |
| P25 Negotiated Floor | $0.0048 | $79.0 |
| P50 Market Median | $0.0062 | $96.0 |

| Cancellation Notice Window | 45 Days | 60 Days |
| Default Renewal Uplift | +7% / yr | +11% / yr |
| Hidden Overage Trap | Accidental Unicode character (single smart-quote or emoji) cuts SMS segment limit from 160 to 70 characters, silently doubling or tripling segment charges. | AI Advanced Bot resolutions and Workforce Management add-ons billed across 100% of agent seats; strict no-downgrade clause during active multi-year terms. |
| Primary Negotiation Lever | Enable Twilio Smart Encoding to strip accidental Unicode, and sign a 12-month minimum monthly spend commit to drop outbound segment rate by 30%–40%. | Move occasional internal escalators (engineers/PMs) to free 'Light Agent' licenses and demand a 15% seasonal seat-flex allowance in the order form. |
