How a Plumbing Business
Used SBA Financing to Scale
A practical example of how a trades business used an SBA 7(a) loan to fund vehicles, equipment, hiring, and territory expansion, growing from a two-person operation to a multi-truck service company.
Composite case study. Individual results vary.
Business Background
The business had built a solid reputation in its service area, with a 4.8-star Google rating and a growing base of repeat residential customers. However, the owners were turning away commercial work because they lacked the equipment, staff, and cash flow to take on larger projects.
The Challenge
The business faced three interconnected challenges:
- Equipment gap: Commercial plumbing jobs required hydro-jetting equipment ($35,000), a second pipe inspection system ($18,000), and a larger service truck ($55,000). The business could not afford these purchases from cash flow.
- Staffing gap: Taking on commercial contracts required hiring 2-3 additional licensed plumbers and an apprentice. This meant $15,000-$20,000 per month in additional payroll before the new revenue would materialize.
- Working capital gap: Commercial clients typically pay on net-30 or net-60 terms. The business needed cash to cover materials, payroll, and overhead while waiting for commercial payments to arrive.
The owners had explored equipment financing and working capital loans separately, but realized they needed a comprehensive solution that addressed all three gaps at once. An SBA 7(a) loan offered the flexibility to fund equipment, hiring, and working capital in a single loan.
The Financing Solution
Through the NBC network, the business applied for an SBA 7(a) loan. After comparing offers from multiple SBA-approved lenders, they secured:
| Term | Detail |
|---|---|
| Loan amount | $850,000 |
| Loan type | SBA 7(a) |
| Rate | Prime + 2.75% (variable) |
| Term | 10 years (working capital and equipment) |
| Guaranty fee | Standard SBA fee (approximately 3% of guaranteed portion) |
| Timeline | 72 days from application to funding |
| Credit score | 705 (primary owner) |
| DSCR | 1.35x (post-loan) |
Use of Proceeds
| Use | Amount |
|---|---|
| Service truck + equipment | $108,000 |
| Hydro-jetting equipment | $35,000 |
| Pipe inspection system | $18,000 |
| Working capital (payroll ramp) | $350,000 |
| Working capital (materials + overhead) | $200,000 |
| Marketing and branding | $30,000 |
| Contingency | $109,000 |
Results and Outcomes
Over the 18 months following funding, the business achieved the following results:
- Revenue growth: Annual revenue grew from ~$480,000 to ~$1.45 million (3x increase), driven by new commercial contracts and expanded service capacity.
- Staffing: Hired 3 licensed plumbers, 2 apprentices, and a full-time office manager. Total employees grew from 3 to 11.
- Fleet expansion: Added 3 more service vehicles, for a total of 5 service vans and 1 box truck.
- Service area: Expanded from a 40-mile radius to a 75-mile radius, capturing two additional commercial corridors.
- Commercial contracts: Signed maintenance contracts with 4 commercial property management companies and 2 restaurant chains.
- Loan performance: All payments made on time. DSCR improved from 1.35x to 1.8x as revenue grew faster than debt service.
Lessons for Other Trades Businesses
- Match the financing to the need. This business needed equipment, staffing, and working capital simultaneously. An SBA 7(a) loan addressed all three in a single facility, avoiding the complexity and higher cost of multiple separate loans.
- Plan for the ramp-up period. The working capital portion funded 6-9 months of payroll and overhead before commercial revenue fully materialized. Without this buffer, the business would have struggled to make payroll while waiting for net-60 payments.
- Use the long term to your advantage. A 10-year SBA term meant monthly payments of ~$9,200 on an $850K loan. A 3-year working capital loan at a higher rate would have meant payments of ~$28,000/month, which would have been unsustainable during the ramp-up.
- Have a contingency fund. The $109,000 contingency covered unexpected equipment repairs, a delayed commercial contract start date, and higher-than-expected insurance premiums.
- Compare offers from multiple lenders. Through the NBC network, the business compared SBA offers from several lenders. Rates, fees, and terms varied. The selected offer had the lowest effective cost and came from an SBA Preferred Lender who processed the loan faster.

Can a plumbing business get an SBA loan?
Yes. Plumbing businesses are well-positioned for SBA 7(a) loans because they have tangible collateral (vehicles, equipment, tools) and steady service revenue. Construction and trades businesses are among the top recipients of SBA 7(a) funding.
How much can a plumbing business borrow with an SBA loan?
SBA 7(a) loans go up to $5 million. The amount a plumbing business qualifies for depends on revenue, cash flow, collateral, and the DSCR (minimum 1.10x). A typical plumbing business borrowing for expansion might qualify for $250K to $2M.
What can a plumbing business use an SBA loan for?
Common uses include purchasing service vehicles, hiring and training technicians, buying equipment, expanding to a new territory, purchasing a commercial property for a shop, or acquiring another plumbing business.
How long does it take to get an SBA loan for a plumbing business?
SBA 7(a) loans typically take 60 to 90 days from application to funding. Working with an SBA Preferred Lender can speed up the process. Equipment financing (a faster alternative for specific equipment) takes 24-72 hours.
Is this case study based on a real business?
This case study is a composite illustration based on common patterns among plumbing businesses that have used SBA financing. It represents realistic scenarios, loan amounts, and outcomes. Individual results vary based on business financials, credit, and lender.
What credit score does a plumbing business need for an SBA loan?
Most SBA lenders require a personal credit score of 680 or higher. However, lenders evaluate the whole business profile including cash flow, collateral, and industry experience. Plumbers with strong revenue and equipment may qualify despite borderline credit.
