Signs of a Bad Bookkeeper: What to Check in QuickBooks in 30 Minutes

Most signs of a bad bookkeeper don’t look like anything. The monthly email shows up, the P&L looks roughly like last month, and nothing feels wrong until your CPA calls in March. Bad bookkeeping is quiet. But it leaves evidence, and you can find most of it yourself in QuickBooks Online in about 30 minutes.

This is not a list of personality flaws. If your bookkeeper misses deadlines or stops answering, we covered that in when to fire your bookkeeper. If you want the symptoms you feel in the business, start with the 7 signs your bookkeeping is a mess. This post is the audit: eight things a bad bookkeeper leaves behind in the file, and exactly where to look.

Before you start: get your own login

You need admin access to your own QuickBooks file. If your bookkeeper owns the subscription and you can’t get in, that is sign zero. The books belong to the business, not to the person keeping them.

The 30-minute check: 8 signs of a bad bookkeeper

1. The bank accounts haven’t been reconciled in months

Reconciling is the core of the job: proving that what QuickBooks says matches what the bank says. Every bank account and credit card should be reconciled through last month’s statement.

Where to look: Open the Reconcile page and choose History by account. Check the last statement date on every account. If any is more than 45 days old, the books are unfinished, no matter how tidy the reports look.

2. There is a Reconciliation Discrepancies account on your P&L

When a reconciliation won’t balance, QuickBooks lets the user add an adjusting entry to force it. That entry lands in an account called Reconciliation Discrepancies. A good bookkeeper finds the difference. A bad one plugs it.

Where to look: Run a Profit and Loss for the year and look for Reconciliation Discrepancies. Any balance means someone forced at least one reconciliation. We broke down the usual causes in bank reconciliation errors.

3. Money is parked in Uncategorized accounts

QuickBooks drops anything it can’t classify into Uncategorized Income, Uncategorized Expense or Uncategorized Asset. Those accounts are an inbox, not a destination. At month end they should be at zero.

Where to look: Profit and Loss and Balance Sheet, year to date. A few hundred dollars from last week is normal. Thousands, or balances that go back months, mean transactions are being imported and never reviewed.

4. Opening Balance Equity isn’t zero

Opening Balance Equity is a temporary account QuickBooks uses when balances are first set up. Once setup is done, it should be cleared. When it keeps growing, someone is usually dumping unexplained differences there to make the balance sheet balance.

Where to look: Balance Sheet, equity section. Anything other than zero deserves a one-sentence explanation from your bookkeeper.

5. Undeposited Funds keeps growing

Customer payments sit in Undeposited Funds (newer files call it Payments to deposit) until they are matched to the actual bank deposit. If they never get matched, the same money often gets recorded twice: once as the payment, and again as a deposit coded straight to income.

Where to look: Balance Sheet. Click the Undeposited Funds balance and check the dates. Payments older than a couple of weeks are a problem. Months of them is a pattern.

6. Your A/R aging is full of customers who already paid

This is the expensive one. The invoice is entered, the customer pays, and the bookkeeper records the payment as a new deposit to income instead of applying it to the invoice. The invoice stays open forever and the revenue is counted twice.

Where to look: Run the A/R Aging Summary. Pick the three biggest balances over 90 days and ask whether those customers really owe you. If you know they paid, the income on your P&L is overstated.

7. Negative balances that can’t be negative

Some accounts can’t go below zero in real life: accounts payable, accounts receivable, inventory, a loan you are paying down. A negative balance there means entries went to the wrong place.

Where to look: Balance Sheet. Scan for minus signs. Then compare each loan balance to the lender’s latest statement. If loan payments were booked entirely to expense, or entirely to principal, the balance won’t match and your interest deduction is wrong.

8. The books are never closed

After a month is reconciled and reported, it should be locked so nobody changes it by accident. With no closing date, last year’s numbers, the ones your tax return was built on, can change without anyone noticing.

Where to look: Settings, then Account and settings, Advanced, and Close the books. No closing date is a sign. Then open the Audit log and look for edits made after your last tax filing that change prior-year transactions.

Worked example: what 30 minutes found in a Fort Worth contractor’s file

A plumbing contractor doing about $1.4 million a year ran these checks after a rough tax season. Here is what came up:

• Checking last reconciled in March, seven months back
• $3,412 in Reconciliation Discrepancies across four forced reconciliations
• $14,230 sitting in Opening Balance Equity, two years after setup
• $41,500 in open receivables, $18,900 of it over 90 days

The owner went down the over-90 list and recognized most of the names. $16,400 of those “unpaid” invoices had been paid months earlier. Each payment was recorded as a fresh bank deposit coded to income, so the revenue was counted twice. For an owner in the 24% federal bracket, that is about $3,936 of tax on income that never existed, plus a year of decisions made on a P&L that was $16,400 too optimistic.

None of it showed up in the monthly reports. All of it showed up in 30 minutes.

What a good bookkeeper hands you every month

The fix is not a nicer bookkeeper. It is a repeatable close. By the middle of each month, you should get:

• Every bank and credit card account reconciled through the prior month’s statement
• A Profit and Loss and a Balance Sheet, not just the P&L
• Zero in the Uncategorized accounts and no new Reconciliation Discrepancies
• A closing date moved forward to the month just finished
• A short note on anything unusual: a big swing, a question, a missing receipt

That is the short version of our monthly bookkeeping close checklist. If you are not getting all five, you are paying for data entry, not bookkeeping.

Found three or more? Here is what to do

One of these signs of a bad bookkeeper can be an honest miss. Three or more is a pattern. Before you change anything, confirm you have admin access and export the reports above, so you have a snapshot of where things stand. Then decide whether to fix it yourself with our step-by-step guide to fixing messy books, or hand it to someone who does cleanups for a living. Either way, price it with real numbers: here is what a bookkeeper actually costs in 2026.
