Key takeaways
- Plumbing companies often mix fast-paying service work with slow-paying project work, and the gap between the two is where cash gets tight.
- Equipment financing fits vans and jetters. Working capital or a line fits materials, payroll, and bigger jobs.
- Steady service revenue is one of the strongest things you can show a funder.
Why plumbers run short on cash
- Stocked trucks. Every service van carries thousands of dollars in parts, fittings, and water heaters before a single call.
- Big-ticket jobs. Repipes, sewer line replacements, and remodels take days of labor and a lot of material up front.
- Commercial and new-construction terms. GCs and developers often pay on progress schedules with retention held back.
- Hiring and training. Adding a licensed plumber or apprentice means payroll starts well before they're fully productive.
- Small residential deposits. In California, home improvement down payments are capped at $1,000 or 10% of the contract price, whichever is less.
Fast service pay vs. slow project pay
Emergency and service calls usually get paid the same day. That steady cash is what keeps many plumbing companies running. The trouble starts when you take on larger project work: a commercial rough-in or a multi-unit repipe can tie up cash for weeks while the service side of the business keeps needing parts and payroll.
The goal: use outside capital to carry the slow-paying project work, so your service cash keeps the trucks stocked and the phones answered.
Funding options for plumbing contractors
| Option | Best plumbing use | Typical speed |
|---|---|---|
| Working capital / MCA | Materials and labor for a specific repipe or commercial job | Often 1–3 business days |
| Business line of credit | Inventory restocks and recurring cash gaps | Several days to a few weeks |
| Equipment financing | Service vans, hydro-jetters, camera and locating equipment | Several days to 2 weeks |
| Invoice factoring | Commercial invoices owed by GCs, developers, or property managers | Often a few days once set up |
| Bank or SBA loan | A shop, a warehouse, or buying another company | Weeks to months |

Run the numbers on a job
Say you land a $95,000 commercial rough-in. Labor and materials run about $68,000, the GC pays on a progress schedule, and you take $30,000 in working capital so the service side doesn't get squeezed.
Illustrative example only. Your rate and terms will differ.
The job still clears $18,600, and your service business keeps running normally. If the job only cleared $7,000, the same funding would wipe out the profit. Our working capital guide shows how to test any job before you sign.
How plumbing contractors qualify
- 6+ months in business and $10,000+ in monthly deposits for most of our funding partners
- An active plumbing license. In California, that's typically the C-36 classification. Outside California, the license your state requires.
- Your last 4 months of business bank statements as PDFs, plus a photo ID
Frequent service deposits show funders consistent revenue. For the full checklist, read how contractors qualify for funding.
Growth playbook
- Protect the service engine. Don't let project work drain the cash that keeps trucks stocked.
- Finance long-life equipment over years, not with short-term money.
- Check payment terms before bidding commercial or new-construction work.
- Run all income through one business account so your deposits tell the full story.
- Know your margin by job type so you know which work can carry a funding cost.

Frequently asked questions
Can plumbing contractors finance service vans?
Yes. Equipment financing is usually the best fit for vans, jetters, and other equipment you'll use for years, because payments are spread over the life of the equipment.
How fast can a plumbing company get funded?
Working capital can often fund within 24 to 48 hours after approval and signing, once your bank statements and ID are in.
Do I need a C-36 license?
Contractor-focused funders usually verify an active license for the work you do. For plumbing in California, that's typically the C-36 classification.
Does mostly cash and card service revenue count?
Revenue counts when it's deposited into your business bank account. Deposit everything consistently so funders can see it.
Do you fund plumbers outside California?
Yes. Funding Expansion works with licensed contractors nationwide.
