Plumbing & Mechanical Contractors
The price you bid the pipe at isn't the price on the invoice.
Copper, PEX, and cast iron get quoted at bid and billed months later at whatever the counter says that morning. Fixtures swap mid-job. Counter tickets pile up across supply-house accounts nobody reconciles. CheckIT verifies every line against the quote you actually got — minutes from upload to flagged.
Where the money goes
Four ways profit leaves a plumbing job.
Commodity price drift on pipe
Copper, PEX, and cast iron quoted at bid rarely match the invoice price months later. Supplier creep lands line by line, and nobody has time to check a 60-line supply-house invoice against the quote.
Rough-in vs. trim purchasing
Two different buy waves on the same job — pipe and fittings early, fixtures and trim late. Invoices that land in the wrong phase distort billing against work-in-place.
Supply-house account sprawl
Techs charge to Ferguson and local supply-house accounts across a dozen jobs. Month-end brings a stack of counter tickets and mystery charges nobody can tie to a job.
Fixture swaps and substitutions
The spec fixture is backordered, the sub-in costs more, and the delta quietly rides through on the invoice unless someone catches it against the original quote.
How CheckIT fits the plumbing workflow
Tools for how plumbing actually buys.
CheckIT Invoice — the live tool — sits between when a supply-house invoice arrives and when you pay it. Drop the invoice and the quote in. The engine flags every line that doesn't match. Every stage answers one of the three money questions on the job — what will it cost, what should you pay, and what did you actually pay versus what you agreed.
