BuilderDesk by QSM

The operating
system for
the building
trade.

One PWA. Jobs, estimates, invoices, drawings, team communication, and client portals — purpose-built for UK sole traders and SME builders.

Built for the trade,
not the office.

BuilderDesk was designed around how builders actually work — not how software companies think they work.
