Bookkeeping for Contractors in Abilene, TX

If you run a contracting business in Abilene — whether that's HVAC, plumbing, electrical, construction, oilfield services, or any other trade — your bookkeeping needs are different from a retail shop or a professional services firm. You're dealing with job-based income, variable material costs, subcontractors, equipment, and a tax situation that can get complicated fast.

Most contractors we work with in the Abilene area aren't behind on their books because they're disorganized. They're behind because the systems built for "regular" businesses don't quite fit how a contracting business actually works. Here's what actually matters.

The single biggest bookkeeping mistake contractors make is treating their business like a single bucket — money in, money out. That works fine for a simple service business. It doesn't work when you have five active jobs at different stages, each with its own materials, labor, and subcontractor costs.

Job costing means tracking every dollar of income and expense back to the specific job it belongs to. When you do this consistently, you can answer questions like:

• Which jobs are actually profitable?
• Are you underpricing certain types of work?
• Where did the margin go on that last big project?

QuickBooks Online has job costing built in through its Projects feature. If you're not using it, you're flying blind on profitability.

This sounds basic, but it's the most common issue we see when a new contractor client comes to us for cleanup work. Personal and business expenses mixed together in one account creates a mess that takes hours to untangle — and it makes your tax return harder and more expensive to prepare.

Open a dedicated business checking account and a business credit card. Run every business expense through those accounts only. This one habit alone will save you significant time and money at tax time.

If you pay a subcontractor more than $600 in a calendar year, you're required to issue them a Form 1099-NEC by January 31 of the following year. Miss this and you risk IRS penalties — and potentially losing the deduction for that subcontractor's pay.

To stay on top of this:

1. Collect a W-9 from every subcontractor before you pay them the first time
2. Track all subcontractor payments in QuickBooks throughout the year
3. Run a 1099 report in December to see who you'll need to file for

We handle 1099 preparation for all of our contractor clients as part of year-end services. It's one of those things that's easy to forget until January rolls around.

Contractors typically have significant equipment and vehicle expenses — and those are some of the most valuable deductions available to you. But they require documentation.

For vehicles: You can deduct either actual expenses (fuel, insurance, repairs, depreciation) or the standard mileage rate (67 cents per mile for 2024). You need a mileage log either way. Apps like MileIQ or QuickBooks' built-in mileage tracker make this easy.

For equipment: Large equipment purchases may qualify for Section 179 expensing or bonus depreciation, which lets you deduct the full cost in the year of purchase rather than depreciating it over several years. This can significantly reduce your tax bill in a year when you've made major equipment investments.

If you're a sole proprietor, single-member LLC, or S-corp owner taking distributions, you're responsible for paying estimated taxes four times a year. The due dates are typically April 15, June 15, September 15, and January 15.

Contractors often have uneven income — a slow winter followed by a busy spring and summer. That makes it tempting to skip estimated payments when cash is tight. The problem is that underpaying triggers IRS penalties, and a large tax bill in April can create a real cash flow crisis.

A simple rule: set aside 25–30% of every payment you receive into a separate savings account. Pay your quarterly estimates from that account. You'll almost certainly have money left over, which becomes your emergency fund or your next equipment purchase.

The most expensive bookkeeping is catch-up bookkeeping. When you let six months of transactions pile up, it takes significantly more time to sort through them — and you lose the ability to make real-time decisions based on your numbers.

Monthly reconciliation is the standard we recommend. At minimum, reconcile your bank and credit card accounts once a month, categorize all transactions, and review a simple profit and loss report. It takes less than an hour when you're current. It takes days when you're not.

A few items that come up regularly for contractors in the Abilene area:

Texas Franchise Tax: If your business is structured as an LLC, corporation, or partnership, you likely owe Texas Franchise Tax annually. The threshold and calculation method depend on your revenue. Many small contractors fall under the no-tax-due threshold, but you still have to file.

Home office deduction: If you run your business from a home office — even just for administrative work like estimates, invoicing, and scheduling — you may qualify for the home office deduction. It requires that the space be used regularly and exclusively for business.

Materials and supplies: Every dollar of materials you purchase for a job is deductible. Keep your receipts organized by job. If you're buying materials at suppliers like Abilene Building Materials or similar local vendors, make sure those charges are going through your business account and getting categorized correctly.

Not every bookkeeper understands the nuances of a contracting business. Job costing, subcontractor management, equipment depreciation, and the seasonal cash flow patterns of trade work are different from what most general bookkeepers deal with.
