What affects cost the most?
Your cost depends on which plan you pick. All plans include a fixed monthly message allowance — Starter 5,000 messages, Growth 25,000, Business 100,000 — with no per-message overage. Higher plans add agents, knowledge-base capacity, custom branding, and faster support targets.
Why does knowledge-base quality matter for cost?
When the bot finds a strong answer in the knowledge base, it can answer faster and more cheaply. Poorly structured content usually increases AI-heavy responses and raises support cost.
When should a team upgrade?
- When support volume consistently hits plan limits.
- When the number of agents or brands grows.
- When conversation history, analytics, or integrations become more demanding.
What happens if usage rises unexpectedly?
Waterwair should make it clear when you are approaching limits so you can either improve answer quality, reduce waste, or move to a larger plan.
