5 Ways an In-House Bookkeeper and a Separate CPA Are Costing Your DFW Business

Yes, we wrote this so DFW owners searching "in-house bookkeeper vs outsourced" would find Mashbooks. We sell outsourced accounting, so read us with that in mind. We'll still give you the honest math, including the cases where hiring someone in-house is the right call.

Here's the setup we see often across North Texas. A business grows, the owner hires a bookkeeper or hands the books to an office manager, and a CPA across town files the returns each spring. It feels covered. It usually isn't.

01

Cost 1: The full cost of an employee, beyond wages

The salary is the number everyone looks at. It's also the smallest part of the story that changes year to year.

The U.S. Bureau of Labor Statistics ↗ puts the median annual wage for bookkeeping, accounting and auditing clerks at $50,670 in May 2025, or $24.36 an hour. That's a national figure. Pay in DFW can run higher or lower depending on experience and the role.

On top of wages, every employer pays its share of payroll taxes. For 2026, according to the IRS ↗, the employer pays 6.2% for Social Security (on wages up to $184,500) and 1.45% for Medicare. Federal unemployment tax (FUTA) is 6.0% on the first $7,000 of each employee's wages, and the IRS ↗ allows a credit of up to 5.4% for state unemployment tax, which can bring the net rate down to 0.6%.

Texas adds its own unemployment tax. The Texas Workforce Commission ↗ taxes the first $9,000 of wages per employee, and for 2026 the entry-level rate for new employers is 2.70%.

Then come the costs that don't show up on a pay stub:

BenefitsHealth insurance, paid time off and any retirement match. In June 2026, benefits made up 30.0% of private-industry employer compensation costs, and wages the other 70.0%, according to the BLS Employer Costs for Employee Compensation release. That 30% includes legally required items like payroll taxes.

TrainingSoftware updates, payroll rule changes, sales tax filings. Someone has to learn them, and the business pays for the hours.

TurnoverWhen a bookkeeper leaves, you recruit, hire and train again. The months in between are usually when the books fall behind.

Vacation and sick coverageWhen your one bookkeeper is out, bills still need paying and payroll still needs to run. Often that lands on the owner.

Tools and seat costsA computer, software licenses and a desk.

The SBA ↗ also reminds employers of the admin that comes with every hire: an EIN, W-4s, a payroll schedule, records to keep and payroll taxes to report quarterly and annually.

Cost stackThe True Cost of an In-House Bookkeeper (Example Scenario)

Base wage: $50,670 (verifiedBLS national median, May 2025)

Employer Social Security, 6.2%: $3,142 (verified rateIRS, 2026)

Employer Medicare, 1.45%: $735 (verified rateIRS, 2026)

Federal unemployment (FUTA), 0.6% net on first $7,000: $42 (verified rateIRS, assumes full state credit)

Texas unemployment tax, 2.70% on first $9,000: $243 (verified rateTWC, 2026 new employer rate)

Benefits (health, paid time off, retirement match)$9,000 (illustrative)

Software, computer and seat$1,500 (illustrative)

Training and continuing education$1,000 (illustrative)

Hiring and turnover, spread over a year$3,000 (illustrative)

Vacation and sick coverage$1,500 (illustrative)

Total example cost$70,832 per year

Plus your separate CPA's fees for the tax returns and any cleanup they bill at tax time.

Example scenario: say a McKinney HVAC company hires a full-time bookkeeper at the national median wage of $50,670. The employer payroll taxes in 2026 come to about $4,162 using the rates above. Add illustrative benefits of $9,000 and another $7,000 for tools, training, turnover and vacation coverage, and the real cost is about $70,800 a year. That's before the separate CPA bills a dime.

What it looks like instead: an outsourced team has no payroll taxes, benefits or turnover for you to carry. You pay for the accounting work, not the seat. If someone on the outsourced team is out, the work still gets done. See how our monthly bookkeeping and accounting service is set up.

Cost 2: Mistakes nobody catches, because nobody reviews the bookkeeper's work

Most in-house bookkeepers work alone. They enter transactions, reconcile what they can, and send reports to the owner. The owner trusts the reports because they have no time to check them.

Here's the problem. Bookkeeping errors rarely look like errors. A loan payment coded entirely as an expense. Owner draws booked as wages. A sales tax liability that never gets cleared. A truck purchase expensed instead of set up as an asset. Each one quietly changes your profit, and your taxable income.

The IRS ↗ says good records help you monitor your business, prepare financial statements, keep track of deductible expenses and support what you report on your tax return. Unreviewed books can do none of that reliably.

Payroll mistakes are the most dangerous. Taxes withheld from employees' pay are called trust fund taxes, because the business holds that money in trust for the government. According to the IRS ↗, a person who is responsible for paying them and willfully fails to can be held personally liable through the Trust Fund Recovery Penalty. That's the owner's own money at risk.

Moji's take

“I started my career as an auditor. The first thing you learn is that a second set of eyes catches what the first set misses. That's not a knock on bookkeepers. It's how good accounting works.”

Example scenario: say an Allen landscaping company's bookkeeper codes every loan payment in full to "Interest Expense" for a year. The principal portion is not a deductible expense. The profit and loss looks worse than reality, the loan balance on the balance sheet never goes down, and the CPA has to untangle it in March. Illustrative cost: 20 hours of cleanup at tax time, plus a return that was almost filed on the wrong numbers.

What it looks like instead: a CPA reviews the books every month. Reconciliations are checked, odd entries get questioned while they're fresh, and payroll tax filings are confirmed. If your books already have a year of problems in them, start with a bookkeeping cleanup and catch-up. Our catch-up guide for owners who are behind walks through it.

03

Cost 3: Two providers who never talk

In the split model, the bookkeeper owns the books and the CPA owns the tax return. They might talk once a year, usually in a rush, usually by email.

That gap costs you in three ways:

Books and taxes drift out of syncThe CPA makes adjusting entries for the return, like depreciation and year-end accruals. Those adjustments often never make it back into QuickBooks. Next year starts from the wrong opening balances.

Nobody owns the whole pictureThe bookkeeper doesn't know which numbers matter for taxes. The CPA doesn't see the numbers until the year is over.

Planning never happensTax planning needs current books and a tax professional looking at them together during the year. The split model rarely delivers either one in time.

If you're unsure which role does what, our article on bookkeeper vs. CPA vs. tax preparer breaks it down.

Example scenario: say a Frisco marketing agency's outside CPA books $40,000 of depreciation and a few accruals on the 2025 return. None of those entries reach the bookkeeper. In 2026, the books show a different equity balance than the return, and the CPA bills extra hours again to reconcile them. Illustrative cost: the same cleanup paid for twice, and a balance sheet the owner can't trust when the bank asks for financials.

What it looks like instead: one team keeps the books and prepares the returns, so the adjustments land in QuickBooks the same week. Your books match your business and personal tax returns, and the person planning your taxes is looking at this month's numbers, not last year's.

Cost 4: Taxes you overpay because nobody plans before year end

This is the one that stings. Most tax savings come from decisions made during the year. After December 31, your CPA can only report what already happened.

Planning before year end is how owners pay their fair share and not a dollar more. A few of the moves that need lead time:

Retirement plansSEP, SIMPLE and Solo 401(k) plans each have their own contribution rules and setup timing. The IRS retirement plan resources for small employers and IRS Publication 560 lay them out. Check the current limits there before you contribute.

Hiring your kidsIf your business is a sole proprietorship, the IRS says wages paid to your child under 18 aren't subject to Social Security and Medicare taxes, and wages to a child under 21 aren't subject to FUTA. The work has to be real and the pay reasonable.

Saving ahead for equipment and trucksBuying in the right year, with the cash planned for it, beats a panic purchase in late December.

Paying estimates on planAccording to the IRS, individuals, including sole proprietors, partners and S corporation shareholders, generally have to make estimated payments if they expect to owe $1,000 or more, and corporations if they expect to owe $500 or more. Underpay and you can owe a penalty.

Entity questionsSome owners ask whether an S corporation election would save them tax. That can be worth discussing with a tax advisor. It isn't something Mashbooks sets up, and it isn't right for everyone.

For the full list, read our guide to small business tax strategies for DFW owners.

Example scenario: say a Plano consulting firm's owner meets the separate CPA for the first time each March. The books show strong profit, but it's too late to fund some retirement options for the prior year, there were no estimated payments, and there's a penalty on top of the balance due. Illustrative result: an owner who wrote a $25,000 check in April and asked, "Why didn't anyone tell me in October?"

What it looks like instead: tax planning during the year with quarterly check-ins and a meeting before year end. Estimates get paid on plan. The owner knows the number before April and has time to act. No year-end surprises.

05

Cost 5: Your team's time pulled away from sales and production, plus your evenings

Not every business hires a dedicated bookkeeper. Many hand the books to an office manager, a dispatcher, or the owner's spouse. That looks free. It isn't.

Every hour your office manager spends matching bank transactions is an hour not spent booking jobs, following up on estimates or answering the phone. Every hour your project manager spends chasing receipts is an hour not spent on the job site.

Then there's the owner. In a lot of DFW businesses, the books happen on Sunday night at the kitchen table. That's time away from family, and it's usually the most expensive hour in the company.

Owners tell us they want three things from their accounting:

The split model with in-house books tends to deliver none of the three.

Example scenario: say a Garland plumbing company's office manager spends 8 hours a week on bookkeeping and the owner spends another 4 hours most weekends fixing what's off. Over 50 weeks, that's 400 office hours and 200 owner hours. If the office manager used even half of those hours to follow up on open estimates, the illustrative upside is far bigger than the cost of outsourcing the books.

What it looks like instead: your office manager runs the office. Your crew lead runs jobs. Payroll, 1099s and Texas sales tax are handled by the accounting team, and the owner gets a monthly report instead of a weekend project. If your crew uses a field app like Jobber ↗, synced data can also feed the books, which we cover in our guide to connecting Jobber, ServiceTitan, Housecall Pro and GoHighLevel to QuickBooks.

When an in-house bookkeeper does make sense

We promised to be fair. An in-house person can be the better choice when:

You have high daily transaction volumeHundreds of invoices, purchase orders or vendor bills a week often need someone on site.

The role is more than bookkeepingIf the job is half office manager, half receptionist and part bookkeeper, an employee may fit better.

You need physical paperwork handled dailyChecks, deliveries, lien waivers or inventory counts on site.

You already have a strong bookkeeperThen don't fire them. Add CPA review and tax planning on top.

That last point matters. The choice isn't always in-house or outsourced. Many growing companies keep an in-house clerk for daily entry and use an outside CPA-led team to review the books monthly, plan taxes and file the returns. What hurts is the version where nobody reviews the work and nobody plans.

07

The outsourced accounting model, explained

The outsourced model replaces two disconnected providers with one integrated team. At Mashbooks, that team is led by Moji Shobowale, CPA, from McKinney. Here's what it covers:

Cleanup first, if neededFix the history and set up a proper chart of accounts, so every number lands in the right place.

Monthly bookkeepingReconciled every month and reviewed by a CPA.

Payroll, 1099s and Texas sales taxPayroll runs through Gusto. For Texas rules, see our Texas small business taxes guide.

Tax planning during the yearQuarterly check-ins, estimates paid on plan and a conversation before year end.

Both returnsYour business return (Form 1120) and your personal return (Form 1040, including Schedule C).

QuickBooks done rightSetup and training on QuickBooks Online through our QuickBooks setup and training service.

Your admin staff is freed up. Your CPA knows your business all year, not just in March. And when good books are in place, they make bigger questions possible: which marketing produces revenue (see how to track marketing spend to revenue), which service lines earn the most, and what each job really makes (see job costing for contractors in DFW).

Moji's take

“Owners don't need more reports. They need someone who looks at the numbers every month and tells them what to do next.”

5 signs it's time to switch

Owners rarely switch accountants on a whim. They switch when something breaks. These are the five triggers we see most.

Checklist5 Signs It's Time to Switch to Outsourced Accounting

You're overpaying in taxes. You find out what you owe in April, with no plan and no estimates.

Your business hit its "teenage stage." More profit, more employees, more complexity than your current setup was built for.

Your current accountant is unresponsive or reactive. You hear from them at tax time, if you can reach them at all.

Your books are a mess. They need cleaning up once and for all, not patched again every spring.

You've outgrown a non-specialist solution. A spouse, an office manager or a generalist bookkeeper got you here, but won't get you to the next stage.
