Brevn Conversation Ceiling

Brevn's four tiers are gated by monthly conversation volume, not seats: Basic at $19 covers 300 conversations, Starter at $39 covers 1,500, Business at $79 covers 6,000, and the top tier reaches 20,000. An agency that sells a flat $600/mo managed chat retainer and puts a busy clinic on Basic will blow through 300 conversations in the first fortnight, then eat overage or upgrade costs out of its own margin. The framework: before quoting any retainer, pull the client's historical contact-form submissions, live chat transcripts, and after-hours missed calls, then multiply by three to estimate chatbot conversation volume. Match that number to the tier, add the agency's setup and management fee on top, and the retainer margin holds. Agencies that skip this step discover the ceiling in month two, when the client's traffic spikes and the tier no longer fits.
