Tax season might not be breathing down your neck just yet. But if you’re a business owner, the warning signs are often already there: unreconciled accounts, vague expense lines, payroll missteps, and reports that don’t reflect reality.
These headaches aren’t just an inconvenience when April rolls around — they can drain cash flow, delay growth, and create a mess that eats away at your time and peace of mind. The good news? Fall is the golden window to get ahead of it. By spotting problems now, you’ll save time, money, and stress — and free up your CPA to focus on the strategic insights that actually move your business forward.
Here are five of the most common bookkeeping red flags every small business owner should keep on their radar — and how to tackle them before they snowball through tax season.
1. Bank Accounts That Haven’t Been Reconciled in Months
The red flag: Picture a daycare director finally sitting down at the end of a long day. After wrangling staff schedules, calming parent concerns, and reviewing licensing paperwork, they open the books. The balance sheet shows $54,000 in cash. But a quick glance at the actual bank account shows just $38,000. Payroll just went through, tuition payments are trickling in, and the toddler room AC had to be replaced last week. But where did the rest go? When asked about the last bank reconciliation, the answer is hazy: “Doesn’t the software handle that automatically?”
Why it matters: If your books say one thing but your bank balance says another, the ripple effects are endless. If cash doesn’t match, everything else is shaky: profit and loss reports, tax filings, even the ability to spot tuition misreporting or fraud. Without it, you’re driving blind.
Clean reconciliations give daycare owners confidence in their numbers—and the clarity to focus on what really matters: caring for children and running a thriving care center.
How to catch it: Ask yourself: when was the last full reconciliation? If you don’t have a clear answer, or if you notice months of skipped reports or high “uncleared” amounts, it’s time to investigate.
Quick fix: Make reconciliation a monthly, non-negotiable task. Whether it’s done in-house or with outsourced support, this one habit can eliminate hours of backtracking during tax season. This post on outsourcing vs. hiring outlines when it makes sense to bring in external help.
2. Expense Categories That Don’t Tell the Full Story
The red flag: It’s a busy weekday morning in a retirement home. The kitchen staff is unloading fresh food deliveries, nurses are checking medical supply cabinets, and maintenance is patching a leak before residents gather for lunch. Every department is moving, every dollar at work. Now imagine the monthly financials. Instead of seeing clear categories—food services, medical supplies, facility maintenance—all of those expenses are lumped together under “Miscellaneous” or “Office Expenses.” Thousands of dollars disappear into a black hole of accounting.
Why it matters: If medical supplies, facility maintenance, and food services are all buried under the same generic label, it becomes nearly impossible to gauge where resources are actually going. That can lead to missed deductions, distorted care budgets, and reporting that doesn’t reflect the true cost of operations. It also forces CPAs (and you) to waste time unraveling what should have been clear from the start.
How to catch it: Pull a general ledger report for any large expense category. If you see snacks, software, and medical supplies all lumped into the same category, it’s time to rework your organization.
Quick fix: Create more specific categories. Separating software subscriptions from equipment purchases, or breaking down facility costs from food services, provides sharper insights and cleaner reporting.

3. Payroll That Doesn’t Line Up
The red flag: At a marketing agency, payroll is always a juggling act. There are full-time employees, part-time creatives, and freelance contractors. But when wage expenses don’t match the payroll tax liabilities — or when benefits never seem to balance — alarm bells start ringing. In some cases, payroll is still entered manually, with inconsistent deductions that never quite add up.
Why it matters: Payroll is one of the most heavily regulated areas of your business. Mistakes here aren’t just messy; they’re expensive. Missteps can lead to IRS penalties, underpaid staff, and serious trust issues with your team. And for your CPA, unraveling payroll discrepancies under a deadline is among the most stressful cleanup jobs.
How to catch it: Compare payroll liability and wage expense accounts to recent pay stubs. Look for mismatches, missing entries, or tax withholding errors.
Quick fix: Whenever possible, sync payroll providers directly with accounting software. Monthly reconciliation is essential. And if payroll is a recurring problem, outsourcing may be the best option, especially for clients juggling multiple employee classifications or benefit structures.

4. Receivables and Payables That Linger Too Long
The red flag: A private school notices receivables that are months overdue — families who swear they’ve paid, but the payments weren’t applied to the right invoices. On the other side, a vendor’s check was cut weeks ago but is still marked as unpaid in the books. Both receivables and payables aging reports show balances that simply don’t reflect reality.
Why it matters: Stale receivables make a business look more profitable than it really is. Lingering payables may lead to underreported expenses or even duplicate payments. In both cases, financial reports are out of step with reality, making it harder to prepare accurate returns or advise on cash flow.
How to catch it: Run an aging report on receivables and payables. Look for balances older than 90 days, duplicate invoice numbers, or open invoices that should have been closed.
Quick fix: Schedule regular cleanup — at least quarterly. Close out fully paid invoices, apply payments correctly, and resolve lingering balances that skew your reporting.
5. Financial Reports That Don’t Make Sense
The red flag: A jewelry shop owner reviews their year-end reports. The P&L statement shows a solid profit, and the balance sheet seems fine at first glance. But when they check their bank account, there’s barely enough to cover next month’s inventory order. Something doesn’t add up—and they can’t figure out why.
Why it matters: When your reports don’t match reality, you lose confidence in your financials. That means second-guessing every decision, wasting hours trying to diagnose the problem, and missing opportunities for growth because you can’t trust the data in front of you.
How to catch it: Watch for inconsistencies like income that spikes without corresponding expenses, negative balances in odd accounts, or totals that shift drastically month to month. Your instincts will let you know when something is wrong, so trust them.
Quick fix: Focus on reconciling the data across core reports, including the trial balance, balance sheet, and P&L. This may require tracing back to earlier transactions or rebuilding some reports from scratch, but the clarity is worth it.
