Built for Accounts, Not Just Calls

Multi-site accounts

One property management customer, forty buildings. Keep site-level history, access notes and billing rules without losing the account-level view of margin.

Contract & PO billing

Tie work to a contract or purchase order, bill on the customer's schedule, and track the PO balance so nobody burns past an authorised amount unnoticed.

Job costing that lands

Labor, material and subcontractor cost posted against the job as it happens — so you know margin during the work, not two months after it closed.

Bid to pay application

Awarded construction work converts into a schedule of values and monthly pay applications with retainage tracked in G702/G703 format.

Residential Plumbing Software Assumes You Get Paid at the Door

Flat-rate price books, one-visit invoices, card on file. That model works when the customer is a homeowner standing next to you. It falls apart when the customer is a regional property manager with net-60 terms, a purchase order limit, and an AP portal.

Commercial plumbing is an accounts receivable business as much as a trade business. The software has to understand contracts, POs, multi-site hierarchies and retainage — or your office staff will rebuild all of it in spreadsheets.

Service Work and Project Work in One System

Most commercial plumbing companies run two businesses under one roof. Service keeps the trucks busy and the cash moving. Construction builds the backlog but bills slowly and holds retainage.

Running them in separate systems means nobody can answer the only question that matters: which side is actually making money this quarter. SubcontractorHub keeps both in one place with one set of costs.

What Contractors Say

Commercial Plumbing Software FAQs

What is commercial plumbing software?

Commercial plumbing software runs the two sides of a commercial plumbing business at once: recurring service work under contract for property managers and facilities teams, and project work bid to general contractors. It combines dispatch, contract and recurring billing, job costing, bid packages, and progress billing with retainage — rather than treating every job as a one-off residential call.

How is commercial plumbing different from residential plumbing software?

Residential plumbing software optimises for speed on a single call: dispatch, flat-rate price book, invoice, collect. Commercial work is billed against contracts and purchase orders, often to a property management company with its own invoicing requirements, and project work bills monthly against a schedule of values with retainage held. The customer is an account with many sites, not a household.

Does it handle multi-site property management accounts?

Yes. A commercial plumbing customer is usually one account with dozens of buildings, each with its own service history, access requirements and billing rules. SubcontractorHub keeps the account hierarchy intact so you can see work and margin by site or rolled up across the whole portfolio.

Can it do contract billing and purchase order tracking?

Yes. Commercial work rarely gets paid at the door. Jobs can be tied to a contract or purchase order, billed on the schedule the customer requires, and tracked against the PO balance so work does not continue past an authorised amount without someone noticing.

Does it support progress billing for plumbing construction work?

Yes. An awarded plumbing bid converts to a schedule of values by phase or area, and monthly pay applications calculate work completed, stored materials, retainage held and current payment due in the AIA G702/G703 format general contractors expect.

Can it run alongside our residential plumbing work?

Yes, and most plumbing companies need exactly that. Service and residential replacement work pays the overhead while commercial contracts and bids build the backlog. SubcontractorHub runs both in one platform with one customer database, so you are not reconciling two systems to find out where you actually made money.
