Why can't you trust the bank balance on its own?
Because the bank balance answers a different question. It tells you what has cleared the account as of this morning. It doesn't tell you what you've already committed, what you forgot to record, or whether a payment went out twice. Your books are supposed to know all of that, and reconciliation is the check that they actually do.
Here's the simplest version of the problem. You pay a supplier by check on the 28th. The supplier sits on it for two weeks. On the 5th your online banking shows a comfortable number, you order stock against it, and then the check clears. The bank was never wrong. It just wasn't the number you needed.
What does reconciliation catch that the balance never shows?
It catches three kinds of gap. The first is timing: checks you've written that haven't cleared, and deposits you've made that the bank hasn't posted yet. Those aren't errors, but they explain why the two numbers differ, and a reconciliation lists them by date so you can see how long each has been waiting. A check that has been outstanding for months is worth a phone call to the person you paid.
The second is mistakes in the books. A sale entered twice, an invoice payment recorded against the wrong customer, a transfer between two of your own accounts booked as income. Bank fees and interest are easy to miss too, because nobody sends you a bill for them. Each one makes your profit figure a little less true, and small errors can sit unnoticed for a whole year.
The third is problems at the bank's end or with the people you pay. A vendor charges your card twice. A subscription you cancelled keeps renewing. A charge appears that nobody in the business recognises. Card processors often pay out your sales with their fees already taken off, so the deposit is smaller than the sales it covers, and the fee needs recording or your sales and your expenses both look wrong. Your account agreement says how long you have to dispute a charge, and some of those windows are short, so it pays to spot a bad charge soon after the statement arrives.
Why every month and not once a year?
Because a short list is easy to clear and a long one isn't. Four weeks after a strange payment, you can usually remember what it was. Eleven months later you're digging through email and guessing. The work of reconciling a month is mostly the same whether you do it on time or late, but answering the questions gets much harder with age.
Order matters too. Each month opens on the balance the previous month closed on, so an error left in March travels into every month after it. The IRS notes that for most small businesses the business checking account is the main source for entries in the business books, and that your books must show your gross income as well as your deductions and credits. If the main source and the books don't agree, the income and expense figures built on them are doubtful.

How often should your accounts be reconciled?
Monthly suits most small businesses, but the right rhythm depends on how your money moves. Find the situation that sounds like yours.
One business checking account, a modest number of transactions, and business spending kept apart from personal. Reconcile once a month, soon after the statement closes. That's the standard rhythm, and at this volume it rarely turns up more than a handful of items to ask about.
Lots of card sales every day, paid out through a processor. Keep the monthly reconciliation, and have someone glance at the deposits against the sales report each week as well. Missing payouts and unexpected fee changes are much easier to chase while they're recent.
Several accounts, business credit cards, a loan or a payment app. Every one of them gets reconciled, checking included. The card statement is where duplicate charges and forgotten subscriptions tend to hide, and a loan balance that doesn't match the lender's statement usually means interest was never split out from the payments.
Personal and business spending mixed in the same account. Reconcile monthly, and separate the accounts as soon as you can. Until then, each mixed payment has to be sorted onto one side or the other before the month can close, and only you know which side it belongs on. A tidy chart of accounts makes that sorting much quicker.
Several months that were never reconciled at all. Don't start with this month. Go back to the last month you know was right and work forward in order, which is what catch-up bookkeeping involves.
What should you get back after a reconciliation?
Ask for the reconciliation report itself, rather than a note saying it's done. It should show the statement's ending balance, the balance in your books, and a dated list of every item that explains the difference. If that list has entries from several months ago, ask why they're still open. Old uncleared items are often where a real mistake is sitting.
You should also get a short list of questions: payments that couldn't be matched to a receipt or an invoice. Answer them quickly. Once the month is reconciled, your profit and loss report is worth reading, because it now rests on numbers that match the bank.
What doesn't reconciliation prove?
It proves the books and the bank agree. It doesn't prove every transaction is in the right category, so a repair bill booked as office supplies will reconcile perfectly and still be wrong. It also can't see cash that never went through the bank, which needs its own record. And if you keep your books on the accrual method, unpaid invoices and unpaid bills won't appear on any statement yet, so they need checking separately.
Monthly reconciliation is part of business bookkeeping, and it's the step that makes the rest of the numbers worth reading.
