The operations layer for solo practitioners, priced in three flat-fee tiers.

Plumbmark is the operations layer for solo accountants and small professional service firms — from the one-operator shop on Solo, to a multi-office, multi-jurisdiction firm on Firm, with Practice bridging the two. One flat fee per tier, no per-seat surcharge, no per-document nickel-and-diming. Stripe isn't wired yet, so each tier's CTA captures the waitlist lead instead of opening checkout.
