Running a plumbing business? You’re not just fixing leaks—you’re managing invoices, expenses, and tax deadlines. If you’ve ever felt overwhelmed by bookkeeping, you’re not alone. Many tradespeople like Aroon is a plumber who uses the cash method of accounting to keep things simple, transparent, and IRS-compliant. This approach isn’t just for accountants—it’s a practical tool for real-world plumbers who want to focus on their craft, not spreadsheets.
In this guide, we’ll break down exactly what the cash method means, why it’s ideal for solo plumbers and small contractors, and how you can apply it to your own business—step by step.
What Does “Aroon Is a Plumber Who Uses the Cash Method” Actually Mean?
At its core, the phrase “Aroon is a plumber who uses the cash method” refers to a specific way of tracking income and expenses for tax purposes. Unlike the accrual method (which records revenue when earned and expenses when incurred), the cash method only counts money when it physically changes hands.
- Income is recorded when you receive payment (e.g., a customer pays you $300 after unclogging their sink).
- Expenses are recorded when you pay for something (e.g., you buy $80 worth of PVC pipes with your business debit card).
This method is IRS-approved for most small businesses, especially sole proprietors and service-based trades like plumbing, electrical work, or HVAC—provided your average annual gross receipts are under $29 million (as of 2025). Source: IRS Publication 538
💡 Fun Fact: Over 80% of small businesses in the U.S. use the cash method because it aligns with actual cash flow—critical for tradespeople who often work job-to-job.
Why Do Plumbers Like Aroon Prefer the Cash Method?
Plumbers operate in a cash-flow-driven world. Jobs come in sporadically, payments can be delayed, and emergency calls don’t wait for your accounting software to sync. The cash method offers real-time clarity.
Key Advantages for Trade Professionals:
- ✅ Simpler bookkeeping: No need to track accounts receivable or payable.
- ✅ Better cash flow visibility: You only report income you’ve actually received.
- ✅ Tax deferral opportunity: If a client pays you in January instead of December, that income shifts to next year’s tax return—potentially lowering your current-year tax bill.
- ✅ Easier for non-accountants: You don’t need advanced training to manage your books.
According to a 2024 survey by the National Association of Plumbing-Heating-Cooling Contractors (NAPHCC), 72% of independent plumbers use the cash method, citing “ease of use” and “alignment with actual earnings” as top reasons.
Cash Method vs. Accrual Method: Which Is Right for Your Plumbing Business?
| When income is recorded | When payment is received | When service is completed (even if unpaid) |
| When expenses are recorded | When paid | When incurred (e.g., invoice received) |
| Best for | Sole proprietors, small contractors | Larger firms with inventory or long-term contracts |
| IRS eligibility | Most small businesses (under $29M revenue) | Required for businesses with inventory over certain thresholds |
| Complexity | Low | High |
🛠️ Real-World Example:
Aroon finishes a bathroom remodel on December 28 but doesn’t get paid until January 5.
- Cash method: Reports income in 2026.
- Accrual method: Must report it in 2025, even though he hasn’t seen the money.
For most plumbers, the cash method prevents paying taxes on income they haven’t yet received—a major financial relief.
How to Implement the Cash Method: A Step-by-Step Guide for Plumbers
You don’t need an MBA to use the cash method. Here’s how to get started:
Step 1: Confirm IRS Eligibility
Most plumbers qualify if:
- You’re a sole proprietor, single-member LLC, or partnership.
- You don’t maintain significant inventory (plumbing parts under $200/job usually don’t count).
- Your average annual gross receipts are under $29 million (2022–2024).

Step 2: Choose Simple Accounting Software
Use tools like:
- QuickBooks Self-Employed
- Wave (free)
- FreshBooks
These auto-categorize transactions and generate cash-basis reports.
Step 3: Record Transactions Only When Cash Moves
- Income: Log when the check clears, Zelle hits, or cash is in hand.
- Expenses: Log when you swipe your card or write a check—not when you receive the bill.
Step 4: Reconcile Monthly
Spend 20 minutes each month matching bank statements to your ledger. This catches errors early and keeps your books audit-ready.
Step 5: File Consistently
Once you choose the cash method, you must stick with it unless you get IRS approval to change (Form 3115). Consistency builds trust with the IRS.
Common Mistakes Plumbers Make with the Cash Method (And How to Avoid Them)
Even simple systems can go wrong. Watch out for:
- ❌ Mixing personal and business accounts: Always use a separate business bank account.
- ❌ Recording income when invoiced: Only log it when paid.
- ❌ Ignoring deductible expenses: Did you buy a new pipe wrench? That’s a write-off—when you paid for it.
- ❌ Forgetting estimated taxes: Cash method users still owe quarterly payments if they expect to owe $1,000+ in taxes.
💬 Pro Tip: Set aside 25–30% of every payment in a separate savings account for taxes. Aroon does this—and never gets surprised in April.
FAQ Section
Q1: Can I switch from accrual to cash method as a plumber?
Yes, but you need IRS approval using Form 3115. Most small plumbers qualify for automatic consent if they meet size and industry criteria.
Q2: Do I need to track unpaid invoices with the cash method?
No. Unpaid invoices aren’t income until received. However, keeping a simple log helps with follow-ups—just don’t include them in your taxable income.
Q3: What if a customer pays me in December 2025 for work done in November?
Under the cash method, you report that income in 2025—the year you received payment, not when you performed the service.
Q4: Are there downsides to the cash method?
It can distort long-term profitability (e.g., a big December payment inflates that year’s income). But for cash-flow-focused trades, the benefits outweigh this.
Q5: Can I use the cash method if I have employees?
Yes! Having employees doesn’t disqualify you. The cash method is based on business structure and revenue—not staffing.
Q6: Does the cash method affect my ability to get a business loan?
Some lenders prefer accrual-based financials for larger loans. But for under $100K, cash-basis records are usually sufficient—especially with 6–12 months of bank statements.
Conclusion
Aroon is a plumber who uses the cash method—not because he’s avoiding complexity, but because he values clarity, control, and cash in hand. For independent tradespeople across the U.S., this accounting approach offers a smarter, simpler path to tax compliance and financial peace of mind.
If you’re tired of guessing your profit or paying taxes on money you haven’t received, it’s time to consider the cash method. It’s trusted by thousands of plumbers, endorsed by the IRS for small businesses, and perfectly suited for the unpredictable rhythm of trade work.
