Switching to Accrual in QuickBooks: Month by Month

You have read the case for accrual accounting. You understand why cash basis distorts your dental practice financials. Your bookkeeper or CPA agrees it is time to switch. Now what?

The honest answer is that switching from cash to accrual in QuickBooks Online is not a single toggle. There is no button that converts your books overnight. It is a transition that happens over two to three months, and if you know what to expect at each stage, it is straightforward. If you do not, it feels chaotic.

Here is what actually changes, month by month, when a dental practice makes the switch in QBO.

Month 1: Opening Balances and Accrual AR Setup in QuickBooks

The first month is foundation work. Nothing changes about how you operate your practice. What changes is how your books capture what already happened.

Setting Up Accounts Receivable

On cash basis, you probably do not have a real accounts receivable balance in QBO. Deposits hit your bank account and get recorded as revenue. There is no intermediate step tracking what is owed to you.

Switching to accrual means building that intermediate layer. Your bookkeeper will pull your current aging report from your practice management software (Open Dental, Dentrix, Eaglesoft) and enter the outstanding balance as an opening AR entry in QBO. This is the total amount of work you have performed but not yet collected.

For most single-location practices, this opening balance is somewhere between $40,000 and $120,000. That is not new money. It is money you were always owed that your books were not tracking.

Adjusting the Chart of Accounts

Accrual accounting requires a few accounts that cash basis does not use. At minimum, your bookkeeper will add or activate accounts for insurance receivables, patient receivables, and contractual adjustments (PPO write-offs). If your chart of accounts is already dental-specific, most of these may already exist but sit at zero.

What Your P&L Looks Like This Month

Month 1 is usually messy. Your revenue line will jump because you are now recognizing production as revenue when work is performed, not when payment arrives. At the same time, you are recording the opening AR balance, which creates a one-time bump. Do not read anything into this month's numbers. It is a transition artifact, not a trend.

Month 2: The First Full Accrual Close

This is the month where the new system starts producing useful data.

How Revenue Recording Changes

Your bookkeeper now records revenue based on production reports from your practice management software, not bank deposits. When your team completes $165,000 in production during the month, that is what shows up as revenue, regardless of how much actually hit the bank account.

Collections still get recorded, but they hit accounts receivable (reducing the balance) rather than revenue directly. The distinction matters: revenue reflects what you earned this month, and collections reflect what you got paid for, which might include work from last month or even two months ago.

Expenses Stay Mostly the Same

Most dental practice expenses are already recorded on something close to an accrual basis even on cash books. Payroll runs on a set schedule. Rent is the same every month. Supply orders get recorded when the bill arrives. The big change is on the revenue side, not the expense side.

The exception is prepaid expenses. If you pay your malpractice insurance annually in January, accrual accounting spreads that cost across all twelve months instead of hitting January with the full amount. Your bookkeeper may set up a few prepaid entries like this, but it is typically only two or three items.

What Your P&L Looks Like This Month

This is your first real accrual P&L. Revenue should closely match your production report. Expenses should look familiar. The difference from your old cash basis P&L is that revenue is now stable and predictable, reflecting actual practice activity rather than insurance deposit timing.

Month 3: Normalizing and Comparing

By the third month, you have two full months of accrual data and can start making real comparisons.

Reconciling AR Against Your PMS

Your bookkeeper reconciles the QBO accounts receivable balance against the aging report in your practice management software. These two numbers should match. If they do not, there is a gap somewhere: a payment that was recorded in one system but not the other, an adjustment that was missed, or a write-off that was not entered.

This reconciliation is the single most important quality check in the transition. If AR in QBO matches AR in Open Dental (or Dentrix, or Eaglesoft), your books are solid. If they do not match, your bookkeeper knows exactly where to dig.

What You Can Finally See

With two clean months of accrual data, you can now answer the questions that cash basis could not:

Production by provider. How much did each dentist and hygienist produce? Not collect. Produce. This is the number that tells you whether your team is performing.

Real overhead percentages. Staffing at 27% of net production. Supplies at 6%. Lab at 5%. These numbers are now stable enough to benchmark against industry standards, because the denominator (revenue) reflects actual work performed.

Collection rate. Net collections divided by net production. If it is in the 98 to 100% range, your collections process is healthy. If it is below that, you know to dig into the aging report and find where money is leaking.

Trends that matter. Is production growing? Is overhead creeping up? Is one provider's production declining? You can see these trends now because the noise from insurance timing is gone.

Common Pitfalls During the Switch

Do not compare Month 1 to anything. The transition month has one-time entries that distort every ratio. Treat it as a setup month, not a data month.

Do not panic about the AR balance. Seeing $80,000 in accounts receivable for the first time can feel alarming. That balance was always there. Your books just were not showing it. It is normal and healthy for a practice collecting through insurance.

Do not switch mid-year for tax purposes without talking to your CPA first. You can switch your management reporting to accrual at any time. But changing your tax filing method requires IRS approval (Form 3115). Most dental CPAs will advise keeping tax on cash and running management reports on accrual. This is standard and works well.

Do not skip the PMS reconciliation. The whole point of accrual is that your books reflect reality. If AR in QBO does not match AR in your practice management software, the books are not reflecting reality. Monthly reconciliation is not optional.

Frequently Asked Questions

Do I have to switch my tax filing to accrual too?

No. Most dental practices keep their tax filing on cash basis and run management reports on accrual. Your CPA files your return on cash because it is simpler and gives flexibility around year-end. Your bookkeeper closes your books on accrual so you can actually manage the business. These are two different reporting purposes and they coexist without conflict.

How long does the transition take?

The setup work (opening balances, chart of accounts adjustments, first accrual close) takes one to two months. By Month 3, you have clean, comparable data. The transition does not require any changes to how your front desk or clinical team operates. It is entirely a back-office accounting change.

Will my monthly bookkeeping cost more on accrual?

It should not change significantly. A bookkeeper who already understands dental will spend roughly the same time closing on accrual as on cash. The difference is that they are pulling a production report from your PMS instead of only reconciling deposits. If your bookkeeper says accrual will double the fee, they may not have dental-specific experience.

What if my bookkeeper does not know how to do this?

This is the most common barrier. Switching to accrual for a dental practice requires someone who understands both QBO and dental practice management software. A generalist bookkeeper who only records bank deposits will not know how to pull production data, set up dental-specific accounts, or reconcile AR against the PMS aging report. If your current bookkeeper cannot do this, it is worth finding one who can.
