Plumbing, heating, and cooling contractors most often get funded through revenue-based financing (a merchant cash advance marketplace) — a working-capital product that approves you on your business bank deposits and monthly revenue instead of your credit score alone. For a trade where you front the cost of copper, condensers, compressors, and payroll weeks before a customer pays, this is usually the fastest way to cover a gap: minimums start around $10,000, most funders will work with a personal FICO of 500 or higher, and approved files commonly fund in 24 to 48 hours. Repayment flexes with your sales — a slice of daily or weekly deposits — so it tracks the seasonal swing between a dead shoulder month and a July heat wave. It is fast capital, not the cheapest capital, and it is never guaranteed; below is how to tell when it fits your shop and when a lower-cost option is the smarter call.
Key takeaways
- Revenue-based funding is approved primarily on business bank deposits and monthly revenue, not credit score — a fit for contractors with strong cash flow but thin or bruised credit.
- Typical entry point is about $10,000; many plumbing/HVAC shops qualify for more as monthly deposits grow.
- Personal credit floors are commonly FICO 500+, well below what a bank term loan or SBA loan requires.
- Clean, complete files often fund in 24-48 hours — fast enough to buy equipment or make payroll mid-project.
- Repayment is a fixed slice of revenue collected daily or weekly, so it rises and falls with your seasonal sales volume.
- Cost is quoted as a factor rate or fee, not an APR, and it is not the cheapest money — match it to a job or asset that earns its keep quickly.
- No legitimate funder can 'guarantee' approval; anyone who does is a red flag.
Why plumbing and HVAC contractors need working capital differently
The trade runs on a structural cash-flow gap. You buy the water heater, the rooftop unit, the fittings, and the permit — and you pay your crew — long before the invoice clears or the homeowner's financing funds. On new-construction and commercial jobs that gap widens into 30-, 60-, even 90-day terms, sometimes with retainage held back until the final walkthrough. A single failed compressor on a rooftop package unit can put four figures of parts on your card before you've billed a dime.
On top of that sits seasonality. Heating calls spike in the first hard freeze; cooling and refrigerant work peak in July and August; spring and fall are the slow shoulder months when you still owe rent on the shop, insurance, truck payments, and payroll. Revenue-based funding is built for exactly this rhythm — because repayment is a percentage of what you actually deposit, a slow February collects less and a booming August collects more. That is the opposite of a fixed bank payment that lands the same whether the phone rang or not. See our merchant cash advance overview for how the mechanics work end to end.
How revenue-based approval actually works
Forget the FICO-first mindset a bank uses. A revenue-based funder underwrites your bank statements. The three numbers that move the decision are: average monthly deposit volume, the number of deposits (steady daily/weekly activity beats one lumpy wire), and your ending balances (few or no negative days signals you can carry a payment). Credit still gets pulled, but a 520 with $60,000 a month in clean deposits will usually beat a 690 with erratic, overdraft-riddled statements.
Because the file is small and the review is cash-flow based, speed follows. A marketplace shops one application to multiple funders, so competing offers come back without you filling out five forms. For plumbing and HVAC shops that means you can often have money in the operating account inside two business days — in time to buy the unit, not two weeks after the customer moved on.
Documents and timeline: what a fast approval actually requires
The single biggest reason a 24-48 hour funding turns into a 6-day slog is a slow or incomplete document package. Have these ready before you apply and you keep control of the clock:
- 3-6 months of business bank statements — the core of the decision. PDF direct-from-bank, not screenshots.
- A signed one-page application with ownership and business details.
- Voided business check or bank verification for funding.
- Driver's license and your business EIN / formation basics.
- Sometimes: a recent A/R aging or a signed contract if you're funding against a specific large job, plus proof of any commercial lease.
Typical timeline: apply and submit statements day one; receive offers same day or next morning; sign and complete a quick bank verification; funds hit the account the following business day. The variables that slow it down are almost always on the applicant side — missing a month of statements, a mismatch between the legal name on the application and the bank account, or unexplained large transfers a funder wants clarified. Tidy the file up front and you protect the speed that made this product worth choosing.
Decision framework: when it fits and when to avoid it
This is fast capital, not free capital. Use it where speed and flexibility earn their premium, and skip it where a cheaper, slower option would do the same job.
Revenue-based funding works best when:
- You need money in days, not weeks — a rooftop unit failed, a job needs materials now, or payroll lands before a big invoice clears.
- Your credit is thin or bruised but your deposits are strong and steady.
- The capital funds something that pays back fast — parts and labor for a job you'll invoice within weeks, or equipment that immediately generates billable work.
- You want repayment that breathes with your season rather than a fixed monthly nut.
Think twice or avoid when:
- You qualify for a bank line of credit or an SBA loan and can wait for it — those cost far less for the same dollars.
- You'd use it to plug a chronic, structural loss rather than a timing gap; flexible repayment doesn't fix an unprofitable book.
- Your margins are thin enough that a daily/weekly holdback would choke the very cash flow you're trying to protect.
- You're tempted to stack multiple advances at once — that's how contractors dig a hole they can't climb out of.
A useful gut check: if the dollars you're borrowing will generate billable revenue faster than the advance is collected back, the math tends to work. If not, slow down and price a term product first.
Example scenarios (illustrative, not quotes)
The figures below are labeled for example to show how contractors match the product to a need — they are not offers, rates, or guarantees, and your terms depend entirely on your own deposits and file.
| Situation | Why revenue-based fits | Example funding need | Repayment shape |
|---|---|---|---|
| Residential HVAC shop, rooftop compressor job, parts due before customer pays | Needs materials in 48 hrs; owner FICO 540 but $55k/mo deposits | For example, ~$25,000 | Small daily slice of deposits; lighter in slow months |
| Plumbing contractor bridging a 60-day commercial invoice | Strong revenue, cash tied up in receivables and retainage | For example, ~$40,000 | Weekly holdback until invoice clears, then reinvest |
| Growing heating/cooling company buying a second service truck and stocking inventory ahead of winter | Wants to capture peak season demand, can't wait on a bank | For example, ~$60,000 | Flexes up in busy winter months, down in spring shoulder |
Notice what's missing: total-payback dollar math. Cost is quoted as a factor rate or fee up front, and what you actually pay tracks your sales, so we won't pretend a single multiplication tells the story. Get the fee and the estimated collection pace in writing, then judge it against the revenue the capital will produce.
Alternatives worth comparing before you sign
A good funder wants you to understand the trade-offs, so weigh these:
- Business line of credit — cheaper and reusable; better for recurring gaps if your credit and time allow. Slower to approve.
- Equipment financing — if the need is a truck, a crane truck, or a big install rig, financing the asset itself is usually cheaper than general working capital.
- SBA loans — lowest cost for larger, longer needs, but weeks of paperwork and strong credit required — rarely a fit for a 48-hour emergency.
- Invoice factoring — if the whole problem is slow-paying commercial customers, factoring the receivable directly can be a cleaner match than an advance.
Revenue-based funding earns its place when speed, a low credit floor, and seasonal flexibility outweigh cost. When they don't, one of the above is the smarter tool. Our merchant cash advance overview lays out the full comparison so you can see where each option wins.
How to protect yourself and choose a legitimate funder
The trade is a target for aggressive brokers. Protect your shop with a few non-negotiables:
- Never trust a 'guaranteed approval.' No legitimate funder guarantees anything before seeing your statements. It's a marketing lie.
- Get the fee/factor and estimated collection pace in writing before signing anything.
- Don't stack. Taking a second or third advance on top of an active one is the fastest route to a cash-flow crisis.
- Read the holdback percentage and frequency — daily vs. weekly changes how it feels against your deposits.
- Watch for junk fees — origination, ACH, or 'processing' charges that aren't disclosed up front.
- Use a marketplace so multiple funders compete for your file instead of you chasing one broker's single offer.
A straight-shooting funder will tell you when a line of credit or equipment loan would serve you better. That honesty, more than the speed, is the signal you've found the right partner.
Frequently asked questions
Can I get a plumbing or HVAC business loan with bad credit?
Often yes. Revenue-based funders typically work with personal FICO scores of 500 and up because the approval leans on your business bank deposits and revenue rather than credit alone. Strong, steady deposits with few negative days can outweigh a low score. Credit is still reviewed, but it's one input, not the gatekeeper.
How fast can I actually get funded?
Complete, clean files commonly fund in 24 to 48 hours. The speed depends almost entirely on your document package — have 3 to 6 months of business bank statements, a signed application, and a voided check ready and you keep the timeline tight. Missing statements or a name mismatch between your application and bank account are the usual causes of delay.
What's the minimum I can borrow?
Minimums typically start around $10,000. Many plumbing and HVAC shops qualify for more as monthly deposit volume grows, since the amount offered is scaled to your revenue rather than a fixed cap.
How does repayment work with seasonal HVAC revenue?
Repayment is collected as a fixed percentage of your revenue, usually daily or weekly. That means a slow spring shoulder month collects less and a booming summer or a winter freeze collects more, so the payment breathes with your season instead of hitting the same fixed amount regardless of sales.
Is this cheaper than a bank loan?
No — revenue-based funding is fast, flexible capital, not the cheapest capital. Cost is quoted as a factor rate or fee, not an APR, and it generally runs higher than a bank line of credit or SBA loan. It earns its place when speed, a low credit floor, and seasonal flexibility matter more than getting the lowest possible cost.
What documents do I need to apply?
At minimum: 3 to 6 months of business bank statements direct from your bank, a signed one-page application, a voided business check or bank verification, and your driver's license and EIN. If you're funding against a specific large job, a funder may also ask for an accounts-receivable aging or the signed contract.
Should I use this to buy a new service truck or equipment?
Usually the asset itself is better financed directly. Equipment financing for a truck or install rig is typically cheaper than general working capital because the equipment secures the loan. Use revenue-based funding for parts, payroll, and job-timing gaps where speed matters and there's no asset to pledge.
Is approval ever guaranteed?
Never. No legitimate funder can guarantee approval before reviewing your bank statements, and any broker who promises a 'guaranteed' approval is a red flag. Approval always depends on your actual deposits, revenue, and file.
