Plumber Service Software (PSS) is an all-in-one platform built for plumbing businesses, from a one-person shop to 100+ trucks. Techs build estimates on-site in minutes using live material prices from Ferguson and SupplyHouse, auto-fill line items in one tap, and send quotes by text or email. Approved estimates turn into scheduled jobs and invoices, then sync to QuickBooks Online. One profile per customer holds every job, estimate, invoice and note, and a shared team inbox handles two-way SMS from your own number. Take payments with Stripe. 89 USD a month includes every feature - no tiers, no add-ons, no per-tech fees.
