Dental Bookkeeping Checklist – Stay Accurate & Compliant

Bookkeeping in a dental office has a way of drifting. Not dramatically, nothing breaks; no alarm goes off. Patients keep coming in – payments keep arriving, and the books look roughly right from the outside. The problem tends to show up later: a year-end that takes twice as long as it should, a tax bill that wasn’t anticipated, a cash flow gap that appeared from nowhere, or a Delta Dental or MetLife remittance that’s been posting incorrectly for three months because nobody checked.

A solid dental bookkeeping checklist doesn’t prevent every problem. What it does is make sure the important things happen every month, in the right order, by whoever owns each task. That consistency is what keeps the books useful rather than just technically present.

This checklist covers five areas: collections and insurance income, expenses and payables, payroll and provider compensation, bank reconciliation, and financial reporting. Work through it at month end and the books stay current. Skip sections regularly and they don’t.

Why Monthly Matters in a US Dental Office

Some businesses can get away with quarterly bookkeeping. A dental office isn’t really one of them.

The revenue side is more complicated than it looks. Insurance reimbursements come in from Delta Dental, MetLife, Cigna, Aetna, United Concordia, and a handful of others, each on different payment schedules, each with their own fee schedules and contractual adjustment rates. Patient payments arrive in multiple forms, co-pays at the front desk, outstanding balance payments, installment plan receipts, CareCredit, and Sunbit financing deposits. Production numbers from Dentrix, Eaglesoft, or Open Dental need to be reconciled against what actually collected. And if you’re running associates on a percentage-based compensation model, their production figures feed directly into what they get paid.

On the expense side, lab fees, supply costs, and equipment maintenance all move month to month. CDT code-level billing errors caught late cost more to fix than errors caught within the same billing cycle. And IRS payroll deposit schedules don’t pause because the books are behind.

Monthly bookkeeping catches all of this while it’s still current. The dental bookkeeping checklist below is built around that rhythm.

1. Collections and Insurance Income

This is where most of the complexity in dental bookkeeping lives. Insurance reimbursements don’t arrive as clean deposits; they come with contractual adjustments, write-offs, and patient responsibility splits that all need to be interpreted and posted correctly. Getting this section right is what makes every other part of the books meaningful.

Insurance reimbursements

Every ERA (Electronic Remittance Advice) received during the month needs to be matched to the corresponding claim and posted with the right breakdown: amount paid by the insurer, contractual adjustment, and any remaining patient portion. If your practice management software isn’t integrated with your accounting platform, this is a manual step, and one that gets messy fast if it’s left until month end.

It’s also worth checking that each major payer is reimbursing at their contracted rate. Delta Dental PPO, Delta Dental Premier, and out-of-network reimbursements are three different rate tiers; posting them interchangeably is a common error. Same goes for in-network vs. out-of-network Cigna or MetLife claims. The contractual adjustment should always reflect the specific plan, not a blended rate.

Insurance reimbursement checklist:

All ERAs for the month received, reviewed, and posted
Contractual adjustments recorded correctly by payer and plan type
In-network vs. out-of-network rates applied correctly per payer
Denials logged and queued for appeal, correction, or write-off
Total insurance collections reconciled to practice management system
Any payer reimbursing below contracted fee schedule flagged for follow-up
EOBs (Explanations of Benefits) filed and accessible for audit purposes

Patient payments

Co-pays, outstanding balances, installment plan receipts, and third-party financing deposits all need to be posted and allocated to the correct patient account. The most common error here is unallocated cash; payments sitting in a suspense account because they couldn’t be matched immediately. Left uncleared, these distort your AR balance and make the books progressively harder to interpret.

Patient payment checklist:

All patient payments posted and allocated to correct accounts
CareCredit, Sunbit, and other third-party financing deposits reconciled to remittance statements
Installment plan payments recorded against outstanding balances
Unallocated or suspense cash cleared
Patient refunds processed, approved, and documented

Production and collections reconciliation

Each month, pull your production and collections report from your practice management system and reconcile it to your accounting records. Production is what was generated in the chair, and collections is what was received. The gap between them sits in accounts receivable. A widening gap over consecutive months signals a collections problem. A narrowing gap with flat production is a positive sign. Neither shows up until someone runs the reconciliation.

Production reconciliation checklist:

Monthly production report pulled from practice management system (Dentrix, Eaglesoft, Open Dental, or equivalent)
Total collections reconciled to accounting records
Net collections rate calculated (collections ÷ adjusted production) and recorded
AR aging report reviewed, distribution across current, 30-, 60-, 90-day columns noted
Accounts over 90 days identified, reviewed, and actioned
Bad debt write-offs reviewed and formally approved before posting

2. Expenses and Accounts Payable

Dental supply costs, lab fees, equipment maintenance, and software subscriptions are the categories that drift above benchmark most often when nobody’s watching. Industry benchmarks give you a useful reference point: supplies typically run 5–7% of collections in a well-managed general practice; lab fees sit around 8–10%, higher for restorative-heavy offices; total overhead excluding doctor compensation usually lands in the 55–60% range. These aren’t rules, but if you’re running materially above them, you want to know monthly rather than at year-end.

Supplier invoices and accounts payable

Every invoice that comes in during the month should be entered, categorized, and approved before it’s paid. Reconcile vendor statements against your AP ledger, what Patterson, Benco, or Henry Schein says you owe, and what your records show should agree. When they don’t, find out why before cutting a check.

Accounts payable checklist:

All supplier invoices received, entered, and categorized
Dental supply invoices coded to correct expense category
Lab fees recorded by case and by lab where possible
Equipment purchases distinguished from repairs and maintenance
Vendor statements reconciled to AP ledger
Payment runs scheduled and approved
Early payment discounts captured where available
Any vendor paid $600 or more tracked for 1099-NEC filing at year-end

Expense category review

Once a month, do a quick pass over the expense categories, not to audit every line, but to catch obvious miscoding. Dental supplies booked as office supplies, a lab bill that landed in the equipment account, and a personal charge that slipped through on a business card. These errors are common in offices where more than one person is processing transactions. Catching them monthly keeps the P&L meaningful.

Expense review checklist:

Expense categories spot-checked for obvious miscoding
Capital expenditures (equipment, leasehold improvements) correctly separated from operating expenses
Personal expenses identified and removed
Lab fees as % of collections calculated and compared to prior month
Supply costs as % of collections calculated and compared to prior month
Section 179 or bonus depreciation opportunities noted for any equipment purchased this month

3. Payroll and Provider Compensation

Payroll in a dental office is more involved than running payroll for salaried staff. If you’ve got associates on production-based or percentage compensation, their pay depends on production data pulled directly from your practice management system, data that needs to be verified before it feeds into payroll. Errors here affect the books and the associate’s trust in the practice. Both are expensive to repair.

Payroll processing

Whether you use Gusto, ADP, Paychex, or run payroll in-house, the journal entries need to be posted to your accounting system correctly for each pay period. Payroll liabilities, employer FICA (Social Security and Medicare), federal and state income tax withholdings, health insurance premiums, and 401(k) contributions, should sit on the balance sheet as current liabilities until they’re remitted, then clear when the payments go out.

Federal payroll tax deposits run on either a semi-weekly or monthly schedule depending on your lookback period and total payroll liability. Missing a deposit deadline triggers a failure-to-deposit penalty that starts at 2% and scales up with how late the payment is. It’s one of the more avoidable IRS penalties a dental office can incur.

Payroll checklist:

Form 941 and quarterly payroll reporting

IRS Form 941 is filed quarterly and reports total wages paid, federal income tax withheld, and both employee and employer Social Security and Medicare taxes. The first quarter covers January through March, with the return due April 30. Keeping monthly payroll records clean makes this quarterly filing straightforward rather than a reconstruction exercise.

Form 941 preparation checklist (apply in month 3 of each quarter):

Total wages and tips paid for the quarter reconciled
Federal income tax withheld verified against payroll records
Employee and employer FICA totals confirmed
Any adjustments for tips, sick pay, or group-term life insurance noted
Form 941 due date on calendar: April 30, July 31, October 31, January 31

Associate and provider compensation

If associates are on a percentage of collections or net production, pull the figures directly from the practice management system for each pay period. Don’t estimate and don’t carry a prior month’s figures forward. Document the calculation. Associates who feel their production numbers aren’t being tracked carefully tend not to stay, and compensation disputes are expensive in both money and time.

Provider compensation checklist:

Production or collections figures pulled from practice management system for each associate
Associate compensation calculated and documented per contracted percentage
Hygienist production and any production bonuses calculated
Associate payments cross-checked against signed associate agreement
1099-NEC prepared for any associate paid $600 or more as an independent contractor

4. Bank Reconciliation

Bank reconciliation is the one task on this dental bookkeeping checklist that has no substitute and no shortcut. Every business bank account, every business credit card, every merchant processing account, reconciled against the corresponding statement, every month. No exceptions.

Unreconciled accounts are where errors hide. In a busy dental office where transactions come in from insurance ERAs, card terminals, financing platforms, and patient portals, they hide quickly and multiply. An unreconciled account isn’t a minor gap; it’s an unknown error of unknown size.

Bank and card reconciliation checklist:

All business bank accounts reconciled to monthly bank statement
All business credit cards reconciled
Credit card terminal deposits reconciled to processor reports (Square, Stripe, or equivalent)
CareCredit, Sunbit, and other financing platform deposits reconciled to remittance reports
Outstanding checks and deposits in transit identified and documented
Any unrecognized or unusual transactions investigated before closing the month
Petty cash reconciled if maintained

One thing worth calling out specifically: card processing deposits almost always arrive net of processing fees. That means the gross amount charged and the amount that lands in your bank account differ. Both figures need to be recorded, gross revenue recognized; processing fee posted as an expense. Posting only the net deposit as revenue understates income and understates expense in equal measure. It’s one of the most common bookkeeping errors in small dental practices, and one of the most easily avoided.

5. Financial Reporting and Tax Awareness

Producing reports and reading them are different activities. A P&L that gets filed without being reviewed doesn’t protect anyone. The monthly close should end with statements that actually get looked at, compared to prior months, compared to budget, and questioned when something doesn’t line up.

Monthly financial statements

Your P&L, balance sheet, and cash flow statement are the core. For a dental practice, the P&L is most useful when it breaks revenue out by type, insurance collections, patient payments, and in-house plan income shown separately rather than lumped together. Overhead categories shown as percentages of collections alongside dollar figures let you track whether your cost structure is trending in the right direction month over month.

Financial reporting checklist:

Monthly P&L prepared and reviewed by ownership or management
Revenue broken down by type: insurance, patient, in-house plan income
Key expense categories shown as % of collections
Balance sheet reviewed for unusual balances or unexpected movements
Cash flow statement prepared
Actual performance compared to prior month and to annual budget
Provider-level production and collections report reviewed

Key metrics to track monthly

A handful of numbers are worth recording every single month, not for lengthy analysis, but for trend visibility. Recorded consistently, they’ll surface problems the P&L alone won’t.

Metrics checklist:

Net collections rate (total collections ÷ adjusted production)
AR over 90 days as % of total AR
New patient count for the month
Lab fees as % of collections
Supply costs as % of collections
Days in AR
Production per operatory (multi-chair practices)
Case acceptance rate if tracked in practice management system

Tax and compliance awareness

Month end is a practical checkpoint for upcoming tax obligations. IRS payroll deposits run on a fixed schedule. Quarterly estimated income tax payments, due April 15, June 16, September 15, and January 15, require your year-to-date income to be current enough to make an informed estimate. And any equipment purchased during the month should be flagged for your CPA, so Section 179 expenses or bonus depreciation options can be evaluated before year-end.

Tax and compliance checklist:

Federal payroll tax deposits current per IRS semi-weekly or monthly schedule
State payroll tax deposits current per state requirements
Quarterly estimated income tax payment due dates confirmed on calendar
Year-to-date net income reviewed against estimated tax payments made
Equipment purchases this month flagged for Section 179 / bonus depreciation review
State dental board license renewal fees and professional dues noted as deductible expenses
Any major income changes flagged to CPA if affecting quarterly estimate

What Gets Missed When the Checklist Doesn’t Get Done

Most bookkeeping problems in dental offices aren’t the result of a single bad decision. They’re the result of things consistently skipped over several months. Here’s what tends to accumulate:

Insurance remittances from Delta Dental, MetLife, or Cigna posted in bulk at month end rather than as they arrive, this is where contractual adjustment errors concentrate, and where in-network vs. out-of-network rate confusion does the most damage

AR aging ignored until it becomes a collections crisis, a 90-day column growing slowly is harder to spot than one that jumps suddenly, which is exactly why monthly review matters

Associate production figures carried forward from a prior month because nobody pulled the current report from the practice management system, this causes both compensation errors and inaccurate production tracking, often simultaneously

Bank accounts left unreconciled for two or three months because everything ‘looks fine’ , by the time the reconciliation happens, the differences have compounded and the source of the original error is harder to trace

Quarterly estimated income tax payments based on last year’s income when this year is running significantly higher, the shortfall lands in April with a failure-to-pay penalty and an underpayment charge on top

Card processing fees not separated from gross revenue, the P&L understates both income and expense, and every ratio calculated from it is slightly off in ways that add up over time

1099-NEC filings missed for associate dentists or independent contractors paid over $600, a straightforward IRS penalty that’s 100% avoidable with current month-by-month tracking

None of these announce themselves. That’s the point of a checklist; it makes the quiet problems visible before they become expensive ones.

Final Thoughts

A dental bookkeeping checklist isn’t a substitute for a good bookkeeper or a good accountant. What is it? The structure that makes their work, and yours, more reliable. When every section gets covered every month, the books stay current, the numbers stay meaningful, and the year-end doesn’t turn into a reconstruction project.

Assign ownership for each section. Set a hard deadline for when the month-end close needs to be complete. And if something on the list is consistently getting skipped, that’s worth understanding, because the sections that get skipped are almost always the ones that matter most when they eventually surface.
