Contractor and Construction Accounting Cost in Houston: 2026 Guide

Key Takeaways

• Most Houston contractors pay $400 to $700 per month under $500k in revenue, $700 to $1,200 from $500k to $1.5M, and $1,200 to $2,500 from $1.5M to $5M.

• Construction accounting costs 30 to 50 percent more than standard bookkeeping because of job costing, WIP schedules, and subcontractor compliance.

• 1099 preparation typically runs $10 to $25 per form, and most Houston contractors file 8 to 40 of them every January.

• A one-time cleanup or QuickBooks setup runs $1,500 to $5,000 if your books are behind or your jobs were never tracked separately.

• Good job costing usually pays for itself. Contractors who price from real job-level numbers routinely find 3 to 8 points of margin they were giving away.

What Houston Contractors Pay for Accounting in 2026

Here are the real numbers. For a Houston contractor doing under $500,000 a year, monthly accounting runs $400 to $700. That covers transaction coding, bank reconciliation, basic job tracking, and a monthly profit and loss you can actually read.

From $500,000 to $1.5 million in revenue, expect $700 to $1,200 per month. At this size you usually have 2 to 6 active jobs at a time, a handful of subs, and enough volume that job costing stops being optional.

From $1.5 million to $5 million, the range is $1,200 to $2,500 per month. This tier adds WIP schedules, percentage-of-completion tracking if you have contracts running past year-end, and monthly job profitability reports. Above $5 million, you are looking at $2,500 to $5,000 per month or a part-time controller arrangement.

For context, a non-construction service business in Houston pays noticeably less at the same revenue. If you want the baseline to compare against, we broke down the standard monthly bookkeeping cost benchmark in a separate guide. Construction sits 30 to 50 percent above those numbers, and the rest of this article explains exactly why.

Why Construction Books Cost More Than Regular Bookkeeping

A retail store has one question: did the business make money this month? A contractor has that question times every open job. Each job is its own little business with its own revenue, materials, labor, sub payments, and equipment charges.

That multiplies the work. Every Home Depot receipt has to land on a specific job, not just in a materials bucket. Every sub invoice needs a job code. Payroll has to split across jobs when your crew works three sites in one week. A bookkeeper who codes everything to one big expense account is not doing construction accounting, they are doing data entry.

There is also a timing problem regular businesses never face. You collect deposits before work starts, buy materials weeks before you bill for them, and wait on retainage months after a job closes. This is why a contractor can show a profit on paper and still miss payroll. If that sounds familiar, read our piece on where the money went when your business is profitable but has no cash, because contractors are the number one case we see.

Job Costing: What It Is and What It Adds to the Bill

Job costing means every dollar in and out gets tagged to a specific job, so at any moment you can see that the kitchen remodel in Bellaire is at 62 percent of budget while the office buildout near the Galleria is bleeding on labor.

Setting it up costs $500 to $1,500 one time. That covers building your cost code structure in QuickBooks Online or QuickBooks Contractor Edition, mapping your estimate categories to those codes, and training whoever enters bills to tag them correctly.

Ongoing, job costing adds roughly $150 to $400 per month to a standard bookkeeping engagement, scaling with job count. A remodeler running 3 jobs pays near the bottom. A commercial GC running 12 concurrent jobs with AIA billing pays near the top.

Is it worth it? Almost always. The typical pattern we see: a contractor thinks every job makes about 25 percent gross margin. Real job costing shows half the jobs make 35 percent and the other half make 8. Once you know which jobs and which customers are the 8 percent problem, you either reprice them or stop taking them. That decision alone is usually worth $20,000 to $60,000 a year for a $1.5 million shop.

WIP Schedules and Percentage-of-Completion

If your jobs finish inside 30 days, you can skip this section. If you run contracts that span months, work-in-progress accounting is where your books either tell the truth or lie to you.

A WIP schedule compares what you have billed on each job against what you have actually earned based on costs incurred. Overbilled jobs mean you are holding customer money you have not earned yet, which feels great until the job finishes and the cash is gone. Underbilled jobs mean you are financing your customer's project for free.

Expect a monthly WIP schedule to add $200 to $500 per month depending on job count and contract complexity. Percentage-of-completion revenue recognition, which the IRS can require for larger long-term contracts, adds tax prep complexity too: a contractor return with POC typically runs $1,500 to $3,000 versus $1,200 to $2,000 for a straightforward one.

One warning from experience: WIP schedules built on unreconciled books are fiction. If your QuickBooks balance and your bank balance disagree, fix that first. We covered how that happens and how to fix it in our guide to reconciliation drift before tax season.

1099 Subcontractor Handling and Compliance

Houston construction runs on subs, and subs mean 1099s. Every unincorporated subcontractor you pay $600 or more in a year gets a 1099-NEC by January 31. Most firms charge $10 to $25 per form, often with a $75 to $150 minimum. A GC with 25 subs is paying roughly $250 to $500 every January.

The form is the cheap part. The expensive part is what happens when it is done wrong. No W-9 on file means you technically owe 24 percent backup withholding on every payment to that sub. Misclassify an employee as a 1099 sub and the IRS can come back for the payroll taxes you never withheld, plus penalties. Texas has no state income tax, but the Texas Workforce Commission runs its own misclassification audits, and construction is their favorite target.

A good accountant collects W-9s before the first check goes out, not in a January panic. If you are already behind on the withholding side, our article on why the IRS treats payroll tax debt differently explains what you are actually facing, because trust fund penalties follow the owner personally.

Setup, Cleanup, and Catch-Up Costs

Almost no contractor calls an accountant with clean books. The typical starting point is 8 to 18 months of transactions coded to nothing, a QuickBooks file with 400 uncategorized entries, and jobs that were never tracked separately.

Cleanup pricing in Houston runs $1,500 to $5,000 as a one-time project. The low end is a few months of catch-up with decent records. The high end is multiple years, mixed personal and business spending, and rebuilding job history from bank statements and text messages with your subs.

A fresh setup for a new contracting business is cheaper: $500 to $1,500 for chart of accounts, cost codes, payroll connection, and bank feeds. If you are just starting out, spend it. Every contractor who paid $4,000 for cleanup wishes they had paid $800 for setup.

• Catch-up bookkeeping, per month behind: $150 to $400

• Full cleanup with job history rebuild: $1,500 to $5,000 one time

• New company file setup with cost codes: $500 to $1,500

• QuickBooks migration from spreadsheets or Wave: $750 to $2,000

Tax Prep and Entity Structure: The Other Half of the Bill

Monthly accounting is only part of what you pay. Annual tax prep for a Houston contractor runs $800 to $1,500 for a Schedule C sole proprietor, $1,200 to $2,000 for an S-corp or partnership return, and $1,500 to $3,000 once percentage-of-completion or multi-state work enters the picture.

Entity structure matters more for contractors than most trades because the self-employment tax math hits hard at construction margins. A contractor netting $120,000 as a sole proprietor is paying self-employment tax on all of it. The same contractor as an S-corp with a reasonable salary typically saves $6,000 to $9,000 a year in payroll taxes, minus the added compliance cost. We walked through the income threshold where an S-corp saves money in detail, including the break-even point where the extra accounting fees stop mattering.

One Houston-specific note: Texas franchise tax. Most contractors under the $2.47 million no-tax-due threshold owe nothing but may still need to file an information report. Above it, your accountant should be running the COGS deduction calculation, because construction businesses usually qualify for the most favorable computation.

How to Keep Your Accounting Bill Reasonable

You control more of this cost than you think. The biggest driver of accounting fees is not your revenue, it is the condition of what you hand over. A contractor who snaps photos of receipts into QuickBooks weekly pays hundreds less per month than one who delivers a shoebox in April.

Three habits cut the bill fastest. First, one business bank account and one business credit card, nothing personal running through either. Second, collect the W-9 before the sub's first check, every time, no exceptions. Third, tag the job on every transaction the day it happens, because your accountant reconstructing job codes three months later is the most expensive data entry in Houston.

Also match the service to your size. A $400,000 handyman operation does not need a monthly WIP schedule. A $3 million GC absolutely does. Paying for reports you do not use is waste; skipping reports your bonding company or bank will eventually demand is a different kind of expensive. A firm that works with contractors will tell you which tier you actually need instead of selling you the biggest package.

Frequently Asked Questions

How much does a construction accountant cost per month in Houston?

For 2026, Houston contractors typically pay $400 to $700 per month under $500,000 in annual revenue, $700 to $1,200 from $500,000 to $1.5 million, and $1,200 to $2,500 from $1.5 million to $5 million. Above $5 million, expect $2,500 to $5,000 per month or a part-time controller arrangement. These ranges assume full-service monthly work: transaction coding, reconciliation, job costing, and financial statements. Bare-bones bookkeeping without job-level tracking costs less, but for a contractor it defeats the purpose. The single biggest variable inside each range is job count. A remodeler with 3 active jobs pays near the bottom of the tier, while a GC juggling 12 jobs with AIA progress billing pays near the top even at identical revenue.

Why does construction accounting cost more than regular bookkeeping?

Because every job is tracked like its own small business. A standard service company needs one profit and loss. A contractor needs company-level financials plus job-level costing, which means every receipt, sub invoice, and payroll hour gets coded to a specific job. Add WIP schedules for contracts spanning months, retainage tracking, deposit liabilities, and 1099 compliance for subs, and the monthly workload runs 30 to 50 percent above a normal business at the same revenue. The premium buys you something specific: knowing which jobs make money and which do not. Contractors who skip job costing to save $200 a month routinely lose ten times that by repeatedly bidding the same unprofitable work.

What does job costing setup cost for a Houston contractor?

A one-time setup runs $500 to $1,500 in Houston. That covers building a cost code structure in QuickBooks Online or Contractor Edition, mapping your estimating categories to those codes, connecting bank and credit card feeds, and training you or your office manager to tag transactions by job. Ongoing job costing then adds roughly $150 to $400 per month to a standard bookkeeping engagement depending on job volume. If your existing file has months of untagged history you want rebuilt, that is a cleanup project on top, usually $1,500 to $5,000 depending on how far back you need job-level numbers. Most contractors only rebuild the current year and start fresh going forward.

How much does 1099 preparation cost for subcontractors?

Most Houston firms charge $10 to $25 per 1099-NEC, often with a minimum fee of $75 to $150 for the batch. A contractor paying 25 subs spends roughly $250 to $500 each January. The deadline is January 31, and late filing penalties start at $60 per form and climb to $330 per form the longer you wait, so the prep fee is trivial compared to the penalty exposure. The hidden cost is missing W-9s. Without one on file, you technically owe 24 percent backup withholding on every payment to that sub, and chasing signatures in January from subs you stopped using in March rarely works. Collect the W-9 before the first check clears.

Do I need WIP accounting for my construction business?

Only if your jobs span more than about 30 days or cross reporting periods. If you finish work inside a month and bill immediately, standard job costing covers you. But once you take deposits, bill on progress, or hold contracts running past year-end, WIP schedules become the only way to know whether you are overbilled or underbilled on each job. Overbilling means you are sitting on unearned cash that disappears when the job wraps. Underbilling means you are financing the customer's project interest-free. Banks and bonding companies also require WIP schedules once you pursue larger commercial work, so contractors planning to grow past $2 million usually need it before they think they do. Expect it to add $200 to $500 per month.

What does it cost to clean up messy contractor books?

Houston cleanup projects run $1,500 to $5,000 as a one-time fee. The low end covers a few months of uncategorized transactions with decent bank records. The high end covers multiple years, commingled personal and business spending, and rebuilding job cost history from bank statements and invoices. Priced per month of catch-up, expect $150 to $400 depending on transaction volume. Get the cleanup done before tax season, not during it. Accountants charge peak rates in February and March, and rushed cleanups produce worse returns. If your QuickBooks balance does not match your bank balance, that reconciliation drift is usually the first thing the cleanup fixes, because every report downstream of bad reconciliation is unreliable.

Should a Houston contractor be an S-corp?

Usually yes once net profit clears roughly $60,000 to $80,000 a year. Below that, the added costs of an S-corp, payroll processing at $50 to $150 per month, a separate 1120-S return at $1,200 to $2,000, and reasonable salary compliance, eat most of the self-employment tax savings. Above it, the math flips fast. A contractor netting $120,000 typically saves $6,000 to $9,000 per year in payroll taxes after all added costs. Construction has one extra wrinkle: your salary must be reasonable for someone running crews and managing jobs, so the IRS expects a real number, not $20,000. The election itself is cheap, usually $250 to $500 plus the first-year payroll setup.

Can I just use QuickBooks myself instead of hiring an accountant?

You can, and under about $300,000 in revenue with short jobs and no subs, plenty of contractors do. QuickBooks Online runs $35 to $100 per month and handles invoicing and basic categorization fine. The wheels come off at three points: when you start paying subs and owe 1099s, when jobs stretch long enough that billing and costs land in different months, and when you stop having time to code transactions weekly. Self-managed contractor books almost always drift, and the cleanup you eventually pay for costs more than the bookkeeping you skipped. A middle path that works: you enter bills and tag jobs, an accountant reconciles monthly and handles compliance for $300 to $500 per month.
