Best POS Software for Plumbing Companies (2026)

Clover fits plumbing shops with a real counter: customers pay deposits, pick up water heaters, or grab fittings while the phone rings. Use the trial to test receipt branding, open tickets, and any apps you rely on for quick lookups. Bundle pricing means you should model hardware swaps if you expand bays. Clover wins when you need peripheral choice more than the absolute lowest software friction.

Square is the honest pick when plumbing owners need dependable card acceptance before they perfect inventory taxonomy. Run trial transactions for deposits, progress draws, and counter sales; reconcile against your accounting export habits. Add inventory fields only as you trust counts—phantom stock hurts dispatch credibility. Square stays lean until Lightspeed-class depth is clearly earning its renewal.

Lightspeed helps plumbing operations that stock SKUs across bins and vendors and need low-stock signals before the next slab-leak weekend. Trial vendor catalogs and purchase orders with whoever actually receives freight. Permissions should separate cost visibility from counter staff. If you only sell services with incidental parts, you may not need this depth—choose it when inventory mistakes show up as lost jobs.
