Three tiers. One flat fee.

Plumbmark prices the book‑of‑work, not the headcount. Solo for the one‑operator firm, Practice for the small firm with a team, Firm for multi‑office, multi‑jurisdiction shops. No per‑seat surcharge. No per‑document nickel‑and‑diming. Stripe isn't wired yet — every tier currently opens a waitlist seat, not a checkout.
