Dental Bookkeeping Guide: Monthly Close, Chart of Accounts & Costs

What dental bookkeeping is, and how it differs from accounting and billing

Dental bookkeeping is the recording and reconciling of every financial transaction of the practice in a general ledger: deposits, expenses, payroll, loan payments, and owner draws, each assigned to an account and tied to a bank or card statement. It answers the question of what happened to the money. Accounting takes those reconciled books and interprets them: tax positions, depreciation elections, entity questions, financial statements, and advice about what the numbers mean. Revenue-cycle or billing work is different again. It lives inside the practice-management system and insurance portals, submitting claims, posting remittances, and working the receivables aging.

The distinction matters because the three are often sold together and the failure points differ. A billing service can collect every claim while the general ledger is months behind. A CPA can file an accurate return from books that were never reconciled to the practice-management system, which is how phantom collections and refunds that were never issued go unnoticed until a sale or an audit. Ask who owns each of the three, and where one hands off to the next.

• Patient ledger, kept in the practice-management system: production by procedure, adjustments and write-offs, and insurance and patient payments posted by date of service and provider.
• General ledger, kept in bookkeeping software: actual deposits by date received, merchant and bank fees, expenses by account, payroll, loans, and equity, reconciled to statements.
• Tax and advisory, done by an accountant or CPA: entity and compensation structure, depreciation and Section 179 elections, estimated payments, returns, and financial-statement review.
• Revenue cycle, handled by the front desk or a billing service: claim submission, remittance posting, appeals, patient statements, and receivables follow-up.

The monthly close for a dental practice

A monthly close is finished when the practice-management system, the bank, the merchant processor, and the general ledger agree, and the differences that remain are named and explained. In dentistry the reconciliation has a step that a retail or professional-services close does not. Collections posted in the patient ledger reach the bank through several channels on different timing, so a day sheet total will rarely equal a single deposit.

The checklist below is ordered so that each step depends on the one before it. A practice that skips the first two steps and reconciles the bank statement alone will usually close on time and still miss posting errors, unapplied credits, and refunds that were approved but never sent.

• Pull the month-end reports from the practice-management system: production by provider, collections by payment type, adjustments and write-offs by type, and the receivables aging. Lock the month once the reports are pulled so later edits are visible.
• Trace patient-ledger collections to the bank by channel: cash and paper checks to deposit slips, card payments to the merchant processor's batch reports, and insurance payments to electronic remittances or mailed checks.
• Record insurance virtual credit card payments at gross, with the processing fee as its own expense, so collections and fee cost are both visible instead of netted.
• Record merchant-processor deposits the same way: gross card collections to income, processing fees to their own account, and month-end fee sweeps matched to the processor statement.
• List every patient refund and open credit balance, confirm each refund cleared the bank, and confirm the credit balances that remain were reviewed by someone other than the person who posted the payment.
• Match laboratory invoices to the cases they belong to and record them in the month the case was seated, not the month the invoice was paid.
• Post payroll from the payroll provider's journal, splitting clinical wages, hygiene compensation, front-office wages, owner compensation, employer taxes, and benefits into their own accounts.
• Split every equipment and practice-loan payment into principal and interest so the balance sheet carries the correct liability and the income statement carries only the interest.
• Reconcile every bank, credit card, and loan account to its statement, then clear uncategorized transactions, undeposited funds, and negative balances before reports are issued.
• Produce the income statement, the balance sheet, and an overhead report that uses the month's gross collections as the denominator, and write down the questions the owner should answer before the next close.

A dental chart of accounts that supports overhead reporting

Overhead percentages are only as good as the accounts beneath them. A general-purpose chart of accounts puts lab fees and dental supplies into cost of goods, combines hygienist and receptionist wages under payroll, and hides merchant fees inside bank charges. The practice then cannot tell whether a supply-cost increase came from volume, price, or a new provider's habits. The grouping below is one way to structure the ledger so that each recurring question has an account that answers it.

Deposits, refunds, and separation of duties

Most bookkeeping failures in a dental office are not arithmetic errors. They are control gaps: one person schedules, posts payments, issues refunds, and adjusts balances, and no one else compares the day sheet to the deposit. Bookkeeping cannot fix that alone, but the monthly close is where the gap becomes visible if the right comparisons are built in.

• The person who posts payments in the practice-management system does not reconcile the bank account, and the person who reconciles does not have edit access to the patient ledger.
• Every day, the day sheet collections total is compared with the deposit slip and the card batch report, and any difference is explained the same day.
• Refunds and adjustments above a set amount are approved by the owner or office manager before they are posted, and the monthly adjustment report is reviewed against that approval list.
• Practice-management-system audit logs for deleted or edited transactions are pulled monthly and reviewed by someone outside the front-office team.
• Payroll changes, new vendors, and new bank payees are approved in writing and matched against the general ledger at the close.

Software: the practice-management system and the general ledger are two different tools

Dentrix, Eaglesoft, Open Dental, Curve, and similar systems are built around the patient chart and the patient ledger. None of them replaces a general ledger. The bookkeeping layer is usually QuickBooks Online, Xero, or Sage, connected to bank and card feeds and sometimes to the payroll provider. The two systems are reconciled to each other at month end. They are rarely integrated directly, and when they are, the integration still needs the same reconciliation.

QuickBooks Online is the general ledger named most often on dental bookkeeping vendor sites. Intuit's published list prices on September 15, 2026 were $38 per month for Simple Start, $85 for Essentials, $140 for Plus, and $340 for Advanced, before promotional discounts. A single-location practice with one bank account and one card account can usually work in Simple Start or Essentials. Class tracking by location or provider, budgeting, and inventory require Plus or higher. Payroll is a separate subscription from any provider.

• Confirm who owns the accounting-software subscription and the administrator login. The practice should own both, with the bookkeeper as an invited user, so the books are not lost when a vendor relationship ends.
• Confirm how bank and card feeds are connected and whether the bookkeeper has view-only or transactional bank access. View-only is enough for reconciliation.
• Confirm how the month is locked in both systems, and who can reopen a closed period.

The dental practice accounting guide covers the layer above the books: production versus collections benchmarks, tax and equipment rules, and the questions to ask before hiring a CPA.

What dental bookkeeping costs: employee, firm, or CPA

There is no single market rate. The published references below are the ones a practice owner can check directly. They are quoted as of the review date and are not a recommendation of any arrangement or provider. LA Trusted Professionals has not reviewed and does not receive payment from any vendor named here.

The Bureau of Labor Statistics reports a median wage of $50,670 per year for bookkeeping, accounting, and auditing clerks in May 2025, with a median of $49,860 in healthcare and social assistance. The occupation held about 1.5 million jobs in 2025 and is projected to decline 6 percent from 2025 to 2035 as software absorbs routine entry. An in-house hire also carries employer payroll taxes, benefits, training time, and the separation-of-duties question above.

Among firms that publish a price for dental bookkeeping, Practice Biopsy lists a lean dental bookkeeping service at $495 per month. Percentology, which ranked first on Google for this query on the review date, describes weekly transaction tracking in QuickBooks Online and one monthly email of questions, and states that it works with more than 100 dental practices. That count is the vendor's own claim and is not verified here. Most other firms, including the Lendio and Dental Accounting Group pages that ranked alongside Percentology, quote by conversation rather than a published price.

How long a dental practice keeps its financial records

Financial records and patient records follow different retention rules. The IRS sets the periods for the books and their supporting documents. State law and the state dental board set patient-record periods. The HIPAA Security Rule sets a retention period for its required policies and documentation, not for the clinical record itself.

• IRS general rule: keep records that support income, deductions, or credits for 3 years from the date the return was filed or due.
• IRS: 6 years if income was underreported by more than 25 percent of the gross income shown on the return.
• IRS: 7 years for a claim for a loss from worthless securities or a bad-debt deduction, which is how uncollectible patient balances written off for tax are documented.
• IRS: employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later.
• IRS: indefinitely if no return was filed or a fraudulent return was filed, and asset records until the limitations period expires for the year the asset is disposed of.
• HIPAA Security Rule, 45 CFR 164.316: retain required policies, procedures, and related documentation for 6 years from creation or from the date it was last in effect, whichever is later. Patient-record retention comes from state law and the state dental board.

Questions to ask before hiring dental bookkeeping help

These questions apply to an employee, a bookkeeping firm, or a CPA firm. They are written so a practice owner can compare answers side by side. This guide does not rank providers or award a status.

• Which reports from the practice-management system do you reconcile every month, and to what? Ask for a sample reconciliation that ties production, adjustments, and collections to bank deposits.
• How do you record insurance virtual card payments, merchant fees, and patient refunds? The answer should separate gross collections from fees.
• Who does the entry, who reviews it, and do you use subcontractors or offshore staff? Confirm the answer in the engagement letter.
• Which chart of accounts will you use, and can you show an overhead report from a dental client with the client's identity removed?
• What is your month-end close deadline, and what happens when the practice sends records late?
• How do you receive bank statements and practice reports, and what patient-level information, if any, do you need? Aggregated production and collections reports usually suffice.
• Who owns the accounting-software subscription and the data if the engagement ends?
• For a CPA or a firm claiming a credential, which state issued the license, and can it be verified with that state's licensing authority?
