It's the fifth of the month, and you want to know if you actually made money in the period that just ended. You open QuickBooks Online, look at a number, and hesitate. Is that number right, or is it just what the bank feed happened to grab?
That hesitation is the whole problem with skipping a real close. Without one, you're making decisions off a pile of transactions instead of a set of numbers you've actually checked.
Why this happens
Most small businesses run their books off a live bank feed. Transactions flow in automatically, and QuickBooks Online guesses at categories. That feels like enough, because the balance on the screen usually looks close to the balance in the bank.
Close isn't the same as correct. Bank feeds miss items, especially ones that clear a day or two after the month ends. They also duplicate items when a payment gets entered by hand and then imported again from the feed. Add in an old outstanding check nobody ever cashed, and your books can drift from reality by a little every month, quietly, with no error message telling you it happened.
The cost isn't abstract. If your cash balance is wrong, you might think you have more room than you do, and commit to a purchase or a hire you can't actually cover. If a duplicate expense inflated your costs, you might quote a job too high, or worse, too low, because you're pricing off numbers that don't reflect what things actually cost. A close catches this before it turns into a decision.
A worked example
Say your checking account shows a balance of $18,400 in QuickBooks Online on the last day of the month. Your bank statement, for the same day, shows $17,900.
That $500 difference could be one thing or several. Maybe a $500 vendor payment cleared the bank on the last day of the month but hasn't hit your books yet because you record bills a few days late. Maybe a customer payment for $500 was entered manually the day it arrived, and then the bank feed brought in the same deposit again, so it's sitting in your books twice.
Until you reconcile, you don't know which one it is, and it matters. If it's the vendor payment, your true cash position is lower than you think, and you should hold off on that equipment purchase you were weighing. If it's the duplicate deposit, your cash balance is overstated by $500, and any pricing or profit decision built on that number is off too.
Reconciliation forces you to find the actual cause instead of guessing. You match every transaction in QuickBooks Online against every line on the statement until the difference is zero. Not close to zero. Zero.
How to set it up
- Pull the statement first. Before you touch QuickBooks Online, download or print the official bank or card statement for the month, showing the closing balance on the statement date.
- Open the reconcile tool for that account. In QuickBooks Online, go to the reconcile screen for the specific bank or credit card account you're closing, and enter the statement's ending date and ending balance exactly as shown.
- Match every line, one at a time. Check off each deposit, withdrawal, payment, and charge in QuickBooks Online against the same line on the statement. Don't rely on the running total looking right; confirm each transaction actually exists on both sides.
- Investigate anything that doesn't match. If a transaction is on the statement but not in QuickBooks Online, add it. If it's in QuickBooks Online but not on the statement, find out why: it may be a duplicate, or a payment that hasn't cleared yet.
- Confirm a zero difference before you finish. QuickBooks Online will show a difference amount as you work. Don't close the reconciliation until that number reads zero. If it doesn't, something is still wrong, and finishing anyway just carries the error forward.
- Repeat for every account separately. Each checking account, savings account, and credit card gets its own reconciliation. A clean checking account tells you nothing about whether the business credit card is accurate.
- List and date any uncleared items. Old outstanding checks or pending charges should be written down with the date they first appeared, so you can follow up if they're still sitting there two or three months later.
- Save the reconciliation report. QuickBooks Online generates a report showing what cleared and what didn't. Keep it. It's the record that the month was actually closed, not just glanced at.
The mistakes that undo it
The most common one is treating "the balance looks close" as good enough, and skipping the line-by-line match. A balance can look right while hiding a duplicate deposit and a missing payment that happen to cancel each other out.
Another is reconciling late, three or four months behind, after so many transactions have piled up that finding the source of a discrepancy takes hours instead of minutes. The further behind you get, the harder each individual reconciliation becomes.
A third is forcing a zero. Deleting or adjusting a transaction you don't understand doesn't fix the problem; it just hides it somewhere else in the books.
Last, some owners reconcile the checking account every month and forget the credit card entirely, because the card statement doesn't feel as urgent. Card feeds miss and duplicate transactions just as often as bank feeds do.
Monthly checklist
- Pull the closing statement for every bank and credit card account.
- Reconcile each account separately in QuickBooks Online to that statement's ending balance.
- Confirm a zero difference on each one before moving to the next step in your close.
- Investigate, don't force, any transaction that doesn't match.
- List uncleared items with the date they appeared, and check whether last month's list cleared up.
- Save each reconciliation report before you move on.
Common questions
How long should reconciliation take once I'm caught up?
For a business with a modest number of monthly transactions, a well-maintained account usually takes well under an hour once you're current. It takes longer the first time, or after a gap, because there's more to untangle.
What if the difference is small, like a few dollars?
Small differences still have a cause, often a bank fee or a rounding entry that hasn't been recorded. Find it and record it rather than writing it off, since small unresolved differences tend to compound over several months.
Can I reconcile without downloading the actual statement?
You can look only at the bank feed, but the feed is what's already in question. The statement is the bank's own record, and it's the one thing you're checking your books against, so it needs to come from the bank directly, not from what QuickBooks Online already imported.
What happens after reconciliation, in the rest of the close?
Reconciliation confirms your cash accounts are accurate. It's typically the first of several steps in a full month-end close, which also covers reviewing accounts receivable and payable, checking that categorization is consistent, and reviewing the resulting profit and loss statement before you call the month final.
North Hudson Bookkeeping sets up this kind of monthly close for clients and keeps it current every month after that, so the numbers are ready when you need them. The first call is free.
