What Plumber Bookkeeping Actually Covers
When plumbers hear the word "bookkeeping," they usually imagine keeping receipts in a shoebox and handing everything to an accountant in March. That's not bookkeeping. That's just luck.
Here's What We Do For Plumbers
We handle bookkeeping for plumbers by tracking every single cent that comes in or goes out. We record every invoice you send to a customer, every trip you make to the supply house, and every single transaction on your business card. We categorize these transactions correctly so your books tell the true, accurate story about your plumbing company. Not an estimate. The facts.
When we work with plumbers in Teaneck, we take care of every aspect of your accounting:
- ✅Income by job and customer. You have to know if certain jobs were profitable and which ones were costing you money. Sometimes a repipe job on the other side of the road will seem like money in the bank, but when you add in materials and callback hours, the job is a total loss.
- ✅Expense categorization. Your expenses aren't just a bucket of costs. Parts, vehicle costs, fuel, tools, insurance, subcontractors. Each category gets placed in its own accounting bucket so the reports you get have real meaning.
- ✅Bank and credit card statements reconciliation. Each month, we match your book accounts against your bank statements to they reconcile. If they aren't, we locate the discrepancy.
- ✅Accounts receivable management. Did the homeowner pay you two weeks after the completion date? We monitor who owes you money and how long they have been owing you money.
- ✅Payroll management. Do you employ mechanics? Their wages, payroll taxes, and payroll benefits need to go into the accounting bucket assigned for that specific purpose.
Our job is to do a great deal more than simply post the daily numbers. When you run a plumbing company, you'll likely run into many situations a regular bookkeeper won't recognize. One example: You bought the parts for a specific job but paid on your supply account, and then all the parts are on one bill at the end of the month. That gets too hard to figure out what the actual cost was for that specific job. We track the costs back to that specific job. That's what job costing bookkeeping is all about. The difference between thinking your plumbing company is busy and thinking it's profitable.
9 out of 10 times when a plumber contacts us, they think they're doing well. Once the bank account looks fine, we dig deeper, looking at profitability by job type. Most plumbers end up being surprised to find a couple of plumbing services that are losing money.
We Handle Your Sales Tax Filings
For many companies in the Teaneck, NJ area, another area of bookkeeping they don't take care of is sales tax filing. For many plumbing services, some of their service fees are taxable, and some aren't. Also, there are some materials used that are taxable and others that are not. We make sure these plumbing company services are categorized correctly so you don't overpay or underpay the New Jersey sales tax on them.
We Handle Your 1099 Preparation & Filings
We also take care of 1099 preparation and submission. If you're paying a drain camera guy or a helper on a 1099 basis, these filings have to be accurate and timely. Failure to file any one of them can leave a business with significant fines.
We Give You Tax-Ready Books
And the last step that no plumber seems to want to talk about is getting you and your books ready to hand over to your accountant at tax time. We make sure all the books for the plumber in Teaneck are ready for your CPA, so your CPA doesn't spend hours cleaning up a mess before they can even start your return. The IRS counts inadequate records among the primary triggers for a small business audit. Clean books aren't a luxury. They are an absolute necessity for a thriving plumbing business.
We Create Your Complete Financial Image
When we talk about bookkeeping for plumbers we're not simply entering basic data. We are creating a complete financial image constructed around the plumbing trade. The service jobs. The new construction jobs. The material markups and the truck costs. Everything is organized and reconciled, available for you to access. This is what empowers you to maintain command over your plumbing company rather than just reacting to the balance in the bank account.
Monthly Bookkeeping Habits That Safeguard Profit
Most plumbers don't find themselves on the verge of business failure because of a single bad plumbing job or a single bad customer. Instead, they end up losing money bit by bit as the weeks and months pass.
We see it every single week in businesses. One of our plumbing clients generates revenue and looks like it's doing well. Then we sit down to do a review and the profit margins speak to another tale entirely. There's an uptick in the cost of materials, and there's the overtime bill from one of the plumbing crews that worked a job outside of West Englewood for longer than a 48 hour span. Had the client received a monthly financial review, the client would have been able to discover this discrepancy and address it before it could grow into a bigger and more expensive problem.
The bookkeeping for plumbers is about establishing monthly habits that prevent a plumbing job's profitability from being diminished.
- Reconcile your bank and credit card accounts by the 10th of the next month. If your records don't tally up with your bank statements, then you are left with nothing more than speculation about where your money went.
- Review job cost reports and compare the estimate for a plumbing job against the actual amount. Any job where costs come in at 10 percent higher than estimate.
- Make sure every transaction is classified appropriately. This involves separating expenses for plumbing materials from expenses for labor, truck costs from the expense of buying tools. When everything is placed in one category, you're left with only a vague overview.
- Review your accounts receivable statements and ask yourself who owes you and for how long. A 60-day old account is not merely a small thing.
- Produce a profit and loss statement. Look at it. Scrutinize it carefully from top to bottom. Examine it from the previous month and last year at the same time. It's here that the P&L provides a safeguard that you can't do anything without.
What is not read in a P&L statement that is simply a file sitting in the company QuickBooks Online software is worthless. We frequently have this surprise for plumbing clients. Your accountant won't monitor this every month, and that's not their responsibility. Your accountant uses whatever you give them. If your figures are a mess or incorrect, so will your tax return be. In fact, the IRS says small businesses are more apt to face audits due to substandard record-keeping than due to unintentional mistakes. So it makes sense to develop the habit of maintaining accurate books on a monthly basis to help protect your business.
Your Cash Flow
Let us know if we can help you put in place a system for monthly bookkeeping. Another habit that we encourage our clients to practice on a monthly basis is checking their cash flow. The plumbing business fluctuates seasonally; there will be busy times (such as winter emergency calls) and slow times. If you don't maintain your cash flow records on a monthly basis, it's easy for cash flow problems to sneak up on you. One thing we do in our reports for our clients is provide simple cash flow statements, so that you can see your position, the cash you should be getting into your business over the next 30 to 60 days, as well as the cash coming out. No surprises!
Check out the various trade contractors we service and find out what we do for them. But the most important habit is consistency, not perfection. You don't have to be an accountant or become an accounting expert. Just have someone keep your books consistently current every month so that you have accurate numbers to work with whenever you need them; that's what we do.
Monitoring Your Payroll
We also pay close attention to maintaining payroll records for our plumbing clients. If you've got techs on your crew, their wages, taxes, and benefits all need to land in the right places on your books. You don't know whether that $15,000 bathroom remodel in Teaneck is profitable or losing money. Think of it this way: Would you put workers out on a project without first understanding the scope of work? Obviously not. Is it any different to operate your business without reviewing your monthly financial statements?
Identifying and Correcting the Most Common Bookkeeping Mistakes
We frequently run into the same situations with our clients. We hear from a contractor in Teaneck who has either an accountant who is frustrated, a tax bill that he thinks doesn't make sense, or has simply decided he can't make sense of his own bookkeeping. 9 out of 10 times, the problem can be attributed to one of these common bookkeeping mistakes which, once identified, are relatively easy to fix.
The most common bookkeeping error contractors make is mixing personal and business expenses in one account. You have lunch with your supplier representative on your personal card and purchase pipe fittings with your business debit card from the same supplier. This leads to a mess; your expenses get categorized incorrectly and your profit is shown higher or lower than it really was. By tax time, you don't know what you can claim as a deduction.
What are the most common bookkeeping errors that plumbers are guilty of when they bring in their books to us?
- Not capturing any cash from a residential job, so you're missing revenue.
- Mixing material expenses all together and not keeping them to the individual job.
- Not balancing your books, and missing monthly reconciliations until it's three or four months too late.
- Not capturing your driving time between residential jobs to say, for example, Glenpointe or West Englewood in Teaneck.
- Not properly classifying sub payments, which could cause 1099 problems at the IRS level.
That one really stands out to me. If you're giving out a check or paying a sub or a helper, and no 1099 is getting generated, that's a huge risk for you. The IRS has a problem. We do a 1099 for the entire thing in the process of the service we're doing so it never gets missed.
Another mistake that I come across constantly is duplicate entries. You've manually entered an invoice, then the bank feed kicks it in there again, and now it looks like you purchased that water heater twice. Now you have inaccurate revenue and incorrect cash flow calculations in QuickBooks Online, and you don't know how to figure out why your bank account is short and the numbers don't add up.
Okay, so here's what we do to address these problems. First, we take the last year, we pull the bank statements and the credit card statements. Then we compare them against the transactions in the QuickBooks to make sure it's correct. We make sure to put it into the right category, and then we fix the errors by eliminating duplicate entries and adding in any that might have fallen off. Then we make sure the books are balanced to the month that it actually happened.
Again, it doesn't make you look good in the moment, but it is the base that you've built your business on. If you're going to get job costing, it's only going to be accurate if your expense categories are correctly coded. If you're going to do a financial budget and you're missing months of income in your revenue, it is going to be totally off. If you're going to go back to your accountant and say I want to maximize my tax write-offs but the books don't match what the bank is saying, there's really nothing they can do.
This plumber in Teaneck thought he was making no money on his after-hours emergency calls, but after we cleaned up the books and created a system for tracking job costings, he realized that the after-hours jobs were his most profitable job. That changed how he scheduled his whole week.
We can Help You!
If you're looking for someone who can go in and help you assess your books, give us a call. What's most important here is that these are common mistakes for plumbers. It doesn't mean that you're a bad businessman. If you're on a service call, or managing a team, or ordering materials, your accounting might be getting pushed until Sunday night and you don't get around to it. That's normal and it's why our service exists. It's what we do at the end of every week, we work with plumbers to determine where the mistakes usually lie before we even open up your file.
The final note here:
If you have a CPA or other tax preparer, let them know that we will be going through your book. We work with accounting firms very often, and it helps your tax prep process down the road if everyone is working with the same information. That's it. We don't need binder after binder filled to the brim with receipts and paperwork. We don't need spreadsheets or complicated accounting files. We need access and a quick overview of what went wrong
Frequently Asked Questions
What does a bookkeeper who specializes in plumbing actually do differently?
A plumbing bookkeeper tracks job costs, material markups, and truck expenses in ways a general bookkeeper won't know to do. For example, if you bought parts on a supply account and got one big bill at month's end, we trace each cost back to the right job. That tells you if a repipe job in Teaneck actually made money — or quietly lost it.
How does bookkeeping help Teaneck plumbers stay ready for New Jersey sales tax filing?
New Jersey sales tax rules for plumbers are tricky. Some labor charges are taxable and some aren't. Some materials are taxable and some aren't. We categorize every transaction correctly so you don't overpay or underpay. Teaneck plumbers who skip this step often get hit with back taxes or penalties they never saw coming. Clean categorization protects you before a problem starts.
How often should a plumbing business review its books?
You should review your books every single month, not just at tax time. Reconcile your bank and credit card accounts by the 10th of the following month. Review job cost reports and compare estimates to actual costs. If a job ran 10 percent over budget — like a crew that worked extra hours out in West Englewood — you want to catch that fast, not six months later.
What happens to my books when tax season comes around?
Your books get handed off to your CPA ready to use — no cleanup needed. The IRS lists poor recordkeeping as one of the top reasons small businesses get audited. When your Teaneck plumbing company has clean, organized books, your accountant spends time filing your return, not fixing your records. That saves you money and keeps you out of trouble.
Do I need bookkeeping help if I only have one or two employees?
Yes, even small plumbing crews in Teaneck need accurate books. Wages, payroll taxes, and 1099 filings for subcontractors all have to be done correctly and on time. Missing even one 1099 for a drain camera tech or a part-time helper can result in real fines. The smaller your team, the more every dollar matters — so your numbers need to be right.
How do I know if certain plumbing jobs are actually profitable?
Job costing reports show you exactly where you made money and where you didn't. Most Teaneck plumbers who contact us think their business is doing well — until we break down profit by job type. It's common to find one or two services quietly losing money. Knowing which jobs pay off lets you price better, bid smarter, and stop doing work that costs you more than it earns.
