5 Signs Your Books Need a Cleanup Before Year-End

Year-end is when accounting problems that have been quietly accumulating all year finally surface — usually at the worst possible time. Messy books slow down your year-end close, inflate your accounting fees, and can lead to missed deductions or inaccurate financial statements.

The good news: most issues are fixable if you catch them early. Here are five warning signs to look for before the clock runs out on your fiscal year.

01 — Your bank accounts haven't been reconciled in months

If your QuickBooks or Xero balance doesn't match your actual bank statement, every financial report you've been looking at is wrong. Unreconciled accounts mean undetected errors — duplicate transactions, missed expenses, or even fraud. Reconciling monthly is the single most basic habit in bookkeeping, and it's the first thing we check when a new client comes on board.

02 — You have a large, unexplained balance in accounts receivable

An AR balance that hasn't moved in 90+ days is a red flag. It could mean invoices were entered but never sent, payments were received and coded incorrectly, or you have genuinely uncollectible amounts that need to be written off. Either way, carrying stale AR inflates your revenue and distorts your financial picture. Run an AR aging report and investigate anything over 60 days.

03 — Expenses keep landing in "Uncategorized" or "Ask My Accountant"

These accounts are placeholders — they're not meant to accumulate a year's worth of transactions. If you have a significant balance in either, it means your books have gaps that need to be filled in before year-end. Uncategorized expenses can't be deducted, and they make your income statement unreliable. Clean these up now, while you still have context for what the transactions were.

04 — Your shareholder loan account has an unusual balance

The shareholder loan account tracks money moving between you personally and your corporation. If it shows a large debit balance — meaning the corporation has effectively loaned money to you — that balance needs to be cleared before your year-end or it could be treated as a taxable benefit. This is one of the most common year-end surprises we see with owner-managed businesses, and it's entirely avoidable with monthly attention.

05 — Your profit and loss doesn't look right — and you're not sure why

If your P&L shows margins that seem too high or too low compared to how the year actually felt, something is wrong. It might be expenses coded to the wrong period, revenue recognized too early, or costs sitting in balance sheet accounts that should have flowed through income. Trust your gut here — if the numbers don't match your lived experience of the business, dig in.

What to Do About It

If that sounds like more than you want to tackle on top of running your business, that's exactly what we're here for. A year-end cleanup doesn't have to be a scramble — with the right support, it can be a clean, predictable process every time.
