How to Do a Bank Reconciliation: Step-by-Step for Small Businesses

March 3, 2026

Bank reconciliation might sound like something only accountants care about, but if you run a small business, it’s one of the most important things you can do to protect your cash flow, catch mistakes, and make smart decisions. In this article, we’ll break it all down into simple steps—no jargon, no fluff.

What Is a Bank Reconciliation?

Bank reconciliation is the process of matching your business’s financial records (your bookkeeping) with your actual bank transactions. It ensures that the money going in and out of your account matches what you have recorded in your accounting system.

When everything matches, you’re reconciled. If there are differences, it’s time to investigate and fix them.

Think of it like balancing your personal chequebook, only for your business—with a few more moving parts.

Why It Matters for Small Businesses

  • Catch errors early – Whether it’s a missed deposit, a double charge, or a bank fee, reconciliation helps you spot problems before they snowball.
  • Prevent fraud – You’ll quickly notice any unauthorized transactions.
  • Stay on top of cash flow – You’ll know exactly how much money you really have to work with.
  • Simplify tax season – Your books are clean and accurate when the CRA comes knocking.

Pro Tip: Reconcile your accounts monthly (or even weekly, depending on transaction volume). Waiting too long only makes it harder.

Step-by-Step: How to Reconcile Your Bank Account

Here’s a simple walkthrough for doing your own bank reconciliation.

Step 1: Gather Your Tools

You’ll need:

  • Your bank statement for the period you’re reconciling (monthly is most common)
  • Your bookkeeping records (from software like QuickBooks, Wave, Xero, or even Excel)
  • A calculator or spreadsheet (if not using accounting software)

Step 2: Compare Opening Balances

Make sure the opening balance on your bank statement matches the opening balance in your accounting records for that month. If not, go back to the previous period and find out why.

Step 3: Check Off Matching Transactions

Go line by line:

  • Match each deposit on your bank statement to the one in your books.
  • Match each withdrawal or payment to your recorded expense.

If everything lines up, check it off.

Step 4: Identify Outstanding Transactions

These are transactions that show in your books but not yet on your bank statement. For example:

  • Cheques that haven’t cleared
  • Recent credit card payments
  • Deposits made at month-end

These aren’t errors; just timing differences. Make a list of them.

Step 5: Spot Discrepancies

Look for:

  • Duplicate entries in your records
  • Missed transactions (e.g. bank fees, interest)
  • Errors in amount or date
  • Fraudulent or unauthorized charges

Correct any bookkeeping errors. If something looks fishy on the bank’s end, contact them.

Step 6: Adjust Your Records

Once you’ve identified the discrepancies:

  • Record missing items (e.g., a $9.95 bank fee)
  • Fix mistakes (e.g., if you accidentally typed $150 instead of $105)

Your accounting system should reflect the correct numbers.

Step 7: Confirm the Ending Balance

Take your bank statement’s ending balance and:

  • Add any deposits in transit (not yet cleared)
  • Subtract any outstanding cheques or payments

The adjusted balance should match your books. If not, go back and review.

Still off by a small amount? Look for transposition errors (typing 54 instead of 45). Also check for skipped transactions or duplicated entries.

Tools to Make Bank Reconciliation Easier

You can reconcile manually or use accounting software. Here’s a quick comparison:

Manual Method (Spreadsheets or Paper)

Pros:

  • No software cost
  • Great for very small businesses

Cons:

  • Time-consuming
  • Easier to make mistakes
  • No automation or bank feeds

Cloud Accounting Software

Popular in Canada:

  • QuickBooks Online
  • Wave (free and Canadian)
  • Xero

Pros:

  • Connect directly to your bank
  • Reconciliation suggestions
  • Easy reporting and audit trail

Cons:

  • Learning curve
  • Monthly cost (except Wave)

Real-Life Example: Reconciliation in Action

Let’s say your bank statement shows a balance of $5,000. But your books say $5,300. Here’s what might be happening:

  • You wrote a cheque for $500 that hasn’t cleared yet.
  • You were charged a $100 monthly bank fee you didn’t record.

$5,000 + $500 (cheque not cleared) = $5,500

$5,500 – $100 (missing bank fee) = $5,400

That’s still $100 off. Keep digging until you find the mistake—maybe a duplicate $100 deposit? Once fixed, both records show $5,300.

Best Practices for Small Business Owners

  • Reconcile regularly (monthly at minimum)
  • Keep digital copies of statements and notes
  • Automate what you can with software and bank feeds
  • Don’t rely on your bank balance alone
  • Get help when needed (a good bookkeeper can save you hours)
