Dental Practice Bookkeeping: Chart of Accounts, Overhead Benchmarks, and Production Tracking

Dental practices generate two parallel sets of numbers: what the practice management software says you produced, and what the bank account says you collected. Most bookkeeping problems in dentistry come from confusing the two — or from a chart of accounts copied from a generic small-business template that can't answer the only questions that matter: what's my overhead percentage, where is it going, and is everything the PMS says I collected actually in the bank?

Key takeaways

• Production lives in your practice management software; the accounting books record collections. The daily reconciliation between them is your first fraud control and your most skipped procedure.
• A dental chart of accounts should break out clinical supplies, lab fees, and staff costs as separate categories — the three lines where benchmark comparisons actually change decisions.
• Healthy general-practice overhead runs roughly 55–65% of collections. Knowing your number is useless without knowing which category is out of range.
• PPO write-offs are not expenses. Booking adjustments as expense lines inflates both revenue and costs and makes every ratio wrong.
• Month-end isn't done until the PMS collections report, the merchant deposits, the bank statement, and the books all tie.

Production vs. collections: keep them separate, reconcile them daily

Production is the fee value of the dentistry performed, recorded in Dentrix, Eaglesoft, Open Dental, or whatever PMS you run. Adjusted production subtracts contractual PPO write-offs. Collections is money received. In a heavy-PPO market like South Florida, gross production can overstate economic reality by 30–40%, which is why every internal report should lead with adjusted production and collections.

The accounting system (usually QuickBooks Online) should record collections as revenue — most practices are cash-basis for tax — and the PMS remains the system of record for production. The critical control connecting them is the daily deposit reconciliation: the PMS day sheet's collections total, split by payment type (cash, check, card, insurance EFT), must match what hits the bank. Card batches settle a day or two late and insurance EFTs arrive netted with virtual credit card fees, so the reconciliation needs to track timing — but it needs to happen. Practices that skip it are the ones that discover a front-desk adjustment-and-pocket scheme three years and six figures in. Deleted transactions, unusual adjustment volumes by a single user, and collections that chronically run below deposits are the classic patterns; the PMS audit log plus a daily tie-out surfaces all of them.

A chart of accounts that answers dental questions

The income and cost structure worth building:

Income: patient payments, insurance payments, other income (whitening/product sales, records fees). Some practices split hygiene collections from doctor collections — useful if you pay hygiene on production or want a hygiene-department P&L. Refunds to patients and insurers get their own contra-revenue line; they're a leading indicator of billing problems.

Direct clinical costs: dental supplies; lab fees (broken out — crowns/bridge, implants, aligners if volume justifies); small equipment under your capitalization threshold.

Staff costs: hygiene wages, assistant/front-office wages, associate compensation, payroll taxes, benefits, retirement contributions. Keeping owner compensation on its own line is essential — otherwise every staff-cost benchmark you compare against is contaminated.

Facility: rent or mortgage interest, utilities, repairs, property insurance, CAM charges.

Everything else: merchant and billing fees, software subscriptions, marketing, malpractice and business insurance, professional fees, CE and licenses, office supplies, interest, depreciation.

What not to do: don't book PPO adjustments as an expense. A write-off is revenue you never had a right to collect; running it through the P&L as both income and expense inflates the top line and wrecks every percentage. Adjustments belong in the PMS and in management reporting, not in the general ledger.

Overhead benchmarks: where your money should be going

Expressed as a percentage of collections, well-run general practices tend to land near:

• Staff wages (excluding owner and associates): 25–30%
• Clinical supplies: 5–7%
• Lab fees: 6–10% for traditional crown-and-bridge workflows — often much lower with in-house CAD/CAM milling, which trades lab cost for equipment cost
• Facility/rent: 5–8%
• Marketing: 2–5% depending on growth stage
• Total overhead before owner compensation: roughly 55–65%

Specialty practices run different profiles — oral surgery and endo carry lower lab and higher supply/anesthesia costs; ortho's aligner lab costs behave differently entirely.

The benchmark's job is to point the flashlight. Staff at 34%? Look at overtime, overstaffed hygiene columns, or under-collected production rather than immediately at wage rates. Supplies at 9%? Look at ordering controls and whether one clinician's material preferences are driving it. Lab at 12%? Check whether the fee schedule ever got updated after lab prices rose. One out-of-range line with a known cause beats a "good" total overhead number nobody can explain.

The monthly close that keeps you honest

A dental month-end worth the name: (1) bank and credit card reconciliations complete; (2) PMS monthly collections report tied to deposited revenue, with a documented timing schedule for in-transit card batches; (3) merchant statements reviewed — processing fees creep, and 2.5–3% of card volume is real money; (4) payroll reports tied to wage expense; (5) loan payments split between principal and interest; (6) a P&L with each category shown as a percentage of collections, compared against budget and the same month last year; and (7) insurance accounts-receivable aging from the PMS reviewed alongside the financials, because AR over 90 days is where collections quietly die.

Cash-basis books are fine for tax, but this hybrid discipline — cash-basis ledger plus PMS production and AR reporting — is what gives you accrual-quality visibility without accrual-level bookkeeping cost.

Practitioner note: If you check only one thing after reading this, run last month's PMS collections report against last month's bank deposits. If nobody in the practice can tie those two numbers within a day's timing difference, that's the gap to close first — before benchmarks, before software, before anything.
