Attio Retainer Stack Model

Attio prices per user per month: Plus at $29 annual or $36 monthly, Pro at $69 annual or $86 monthly, with a Free tier capped at 3 seats. That per-seat number is the floor of every agency retainer built on it, not the price of the engagement. The stack model says you price the retainer against three layers: seat cost multiplied by the client's actual headcount, the setup labor of 2-3 days per client to clone a master workspace and wire lead routing from email, Typeform, and webhooks, and the ongoing optimization hours. A five-seat Pro client at $69 annual costs $345/mo in seats before any agency time, so a $297/mo retainer on that account loses money. Run the seat count first, then set the retainer above seat cost plus setup amortization. Agencies that skip this step discover the margin problem two invoices in, when the client adds two sales hires and the seat line grows without the retainer moving.
