You just quoted a job based on what you think you're making this year. Truth is, the last time you looked at real numbers was back in February when your bookkeeper asked for statements. Everything since then has been a guess dressed up as a decision.
Why this happens
Most small business owners don't avoid their books on purpose. They're busy running the business, and the books feel like something that happens once a year, around tax season, when someone asks for records.
That works fine for filing. It doesn't work for running the business day to day. If the last time you looked at real numbers was months ago, every pricing decision, hiring decision, and spending decision since then has been made on stale information.
Say you think you're having a good year because the bank balance looks healthy. But you haven't reconciled since spring, so that balance includes a customer deposit for a job you haven't started, a card payment that hasn't cleared, and a chunk of change that's really owed to a supplier next week. The number in front of you isn't wrong, exactly. It's just not telling you what you think it's telling you.
The cost isn't abstract. Owners who work off old numbers tend to underprice jobs because they don't know their real costs have crept up. They hire before they can actually afford the extra payroll. They keep paying for a subscription or a vendor they forgot about because nothing forced them to look. None of these are big dramatic mistakes. They're small, quiet ones that add up over a year.
A worked example
Say you run a small service business and you check your bank balance in early October: $18,000. Feels solid. You start thinking about bringing on a part-time helper.
Then you actually reconcile the accounts and read the profit and loss for September. Turns out $4,000 of that balance is a deposit a customer paid for a job scheduled in November. Another $1,500 is sitting there because a supplier bill hasn't been paid yet, though it's due in ten days. And your card statement shows $600 in charges that haven't posted to the bank feed at all.
Once those are accounted for, your real available cash is closer to $11,900 ($18,000 minus $4,000 minus $1,500 minus $600). Your September profit and loss also shows that materials costs rose compared to prior months, which is squeezing your margin on the jobs you've already priced.
None of this means don't hire. It means you now know what you're actually working with, and you can make that hiring call, and your next round of pricing, based on real numbers instead of a bank balance that was telling a partial story.
How to set it up
- Pick a day in the first week of every month and put it on your calendar as a recurring block, 30 minutes. Treat it like a client meeting you can't move.
- Open QuickBooks Online and pull up each bank and credit card account you use for the business. Don't skip the ones you rarely touch.
- Reconcile each account against the actual statement, matching every transaction until the ending balance in QuickBooks matches the statement balance. QuickBooks Online has a reconcile tool built for this under the accounting menu.
- Investigate anything that doesn't match. A stray transaction, a duplicate charge, or a missing deposit almost always points to something worth knowing about.
- Run the profit and loss report for the prior month once reconciliation is clean. Compare it to the month before, and to the same month last year if you have that history.
- Note anything that moved, higher costs, a slow month for a particular service, a jump in a specific expense category, and decide if it needs action or just watching.
- Do this before you make any pricing, hiring, or big purchase decision that month, so you're working from numbers that are at most a few weeks old.
What undoes it
The most common failure is letting the monthly block slide "just this once" and then not doing it again until three months have piled up. At that point reconciling feels like a chore instead of a quick check, and it's tempting to skip it again.
Another one is reconciling the bank account but skipping the credit card. Card activity often includes the timing gaps that distort your real cash position the most.
Some owners reconcile but never actually read the profit and loss afterward. The reconciliation confirms your numbers match the bank, which is a necessary first step but not the same as knowing what they mean. The profit and loss is what tells you something useful about the business. Skipping that step means you did the work and missed the point.
Last one: making the close so complicated that it takes half a day instead of 30 minutes. If every month turns into a hunt for missing receipts or unexplained transactions, something earlier in the process, like how expenses get entered, needs fixing so the close itself can stay short.
Monthly close checklist
- Block 30 minutes in the first week of the month
- Reconcile every bank account against the statement
- Reconcile every credit card account against the statement
- Resolve any transaction that doesn't match cleanly
- Run the profit and loss for the prior month
- Compare it to the month before and, if possible, the same month last year
- Flag any category or number that moved more than expected
- Use what you find before making pricing, hiring, or spending decisions that month
Common questions
What if I'm behind by several months already?
Reconciliations have to go in order, because each month's opening balance depends on the month before it. Start from the last month that reconciled cleanly and work forward to the present. While that catch-up is underway, be careful about making big decisions from the unreconciled numbers.
Do I need to reconcile every account, even ones I barely use?
Yes. A rarely used account is exactly where an old subscription charge or a forgotten fee tends to sit unnoticed. It usually takes just a few minutes once you're set up.
What should I actually be looking for in the profit and loss?
Look at whether income and major expense categories moved compared to the prior month and to the same month last year. Whether a specific number is a problem depends on your business, your season, and what's normal for you, so don't chase every fluctuation. Look for patterns that repeat over two or three months.
Can QuickBooks Online remind me to do this every month?
Your own calendar is the simplest reminder. QuickBooks Online's recurring transactions can remind you about specific bills or entries, but a standing calendar block works better for the close itself. The tool matters less than actually protecting the time each month.
North Hudson Bookkeeping sets up this kind of monthly close for clients and keeps it current every month, so the numbers are ready when you need to make a decision, not just when it's time to file. The first call is free.
