7 Mistakes You're Making with QuickBooks Online (and How to Fix Them)

Hey there! If you're running a small business and using QuickBooks Online, you're already ahead of the game. But here's the thing – even the best accounting software can't work miracles if we're not using it right.

I'm Justin from Red Leaf Bookkeeping, and I've seen these same QuickBooks mistakes pop up again and again with our clients. The good news? They're totally fixable, and I'm here to walk you through exactly how to get back on track.

Mistake #1: Skipping Monthly Bank Reconciliations

What's happening: You're trusting that those bank feeds mean everything's perfect in your books. I get it – it feels like magic when transactions automatically appear in QuickBooks! But here's the reality: bank feeds don't catch everything, and they definitely don't catch duplicates or missing transactions.

The Red Leaf fix: Set aside 30 minutes every month (yes, every single month) to reconcile your accounts. Think of it like balancing your checkbook, but way easier.

Here's my simple process:

  • Log into QuickBooks and go to the Banking tab

  • Click "Reconcile" for each account

  • Match your ending balance with your bank statement

  • Review any discrepancies line by line

Trust me, catching a $500 duplicate transaction in January is way better than discovering it in December when you're scrambling for tax prep!

Mistake #2: Playing Fast and Loose with Transaction Categories

What's happening: You're either letting QuickBooks auto-categorize everything without checking, or you're just picking whatever category seems "close enough." Both approaches are setting you up for messy financial reports and potential tax headaches.

The Red Leaf fix: Slow down and be intentional with your categories. I know it takes an extra minute, but that minute saves hours during tax season.

Here's what I recommend:

  • Create a simple category cheat sheet for your most common expenses

  • When in doubt, ask yourself: "If the IRS looked at this, would it make sense?"

  • Review your Profit & Loss report monthly – weird spikes usually mean something got miscategorized

Pro tip: If you're seeing "Office Supplies" as your biggest expense category, something's probably wrong (unless you literally run an office supply store!).

Mistake #3: Creating a Hot Mess with Bank Connections

What's happening: Either you're manually entering everything (exhausting!), or you've connected accounts but created duplicate transactions in the process. Both scenarios lead to inaccurate books and major reconciliation headaches.

The Red Leaf fix: Connect your accounts properly from the start, and use QuickBooks' matching features the right way.

Step-by-step setup:

  • Go to Banking > Connect Account

  • Use your actual bank login (yes, it's secure!)

  • When you first import, carefully review older transactions

  • Always use "Find Match" instead of "Add" when you see a transaction you've already entered

Already have duplicates? Don't panic! Click into the duplicate transaction, select "More," then "Delete." Your books will thank you.

Mistake #4: Using a Generic Chart of Accounts

What's happening: You started with QuickBooks' default industry template and never customized it. Now you've got account categories that don't match your actual business, making your reports confusing and less useful.

The Red Leaf fix: Customize your Chart of Accounts to actually reflect your business. This isn't about being fancy – it's about making your financial reports tell the real story of your business.

Quick customization checklist:

  • Review each account type and make sure it's actually relevant to your business

  • Combine similar categories that you'll never need to track separately

  • Add specific categories for your biggest expense types

  • Remove categories you'll never use (yes, you can delete them!)

Mistake #5: Mixing Personal and Business Finances

What's happening: You're using your business credit card for personal purchases, or your personal account for business expenses. Maybe you started your business with personal funds and never separated things properly.

The Red Leaf fix: Clean separation, starting now. I know it can feel like a hassle, but this is non-negotiable for accurate bookkeeping.

Here's your action plan:

  • Open a dedicated business bank account if you don't have one

  • Get a business credit card for business expenses only

  • Only connect your business accounts to QuickBooks

  • If you need to use personal funds for business, record it as an owner contribution

Already mixed things up? No judgment here! We can help you untangle personal and business transactions – it's more common than you think.

Mistake #6: Playing Accounting Expert with Journal Entries

What's happening: You watched a YouTube video about journal entries and now you're using them to "fix" every problem in QuickBooks. While the intention is good, incorrect journal entries can create way bigger problems than they solve.

The Red Leaf fix: Step away from the journal entries! Unless you're a trained accountant, stick to QuickBooks' standard forms and features.

Instead of journal entries, use:

  • Invoices for customer sales

  • Bills for vendor expenses

  • Bank deposits for income

  • Checks for expense payments

  • Transfer functions for moving money between accounts

When you do need journal entries: Call us! Seriously, some situations do require them, but they need to be done correctly to maintain your double-entry accounting integrity.

Mistake #7: Ignoring User Permissions and Settings

What's happening: You've given everyone admin access because it's easier, or you've never bothered to customize your default settings. This leads to accidental changes, incorrect automation, and general chaos in your books.

The Red Leaf fix: Take control of who can do what in your QuickBooks, and set up your defaults to work for your business.

User permissions checklist:

  • Admin access only for owners and bookkeepers

  • Limited access for employees who just need to enter time or expenses

  • View-only access for anyone who just needs to see reports

Default settings to review:

  • Payment terms on invoices

  • Expense categories for common purchases

  • Sales tax settings

  • Invoice templates and branding

You Don't Have to Go It Alone

Look, I get it – QuickBooks can feel overwhelming, especially when you're trying to run a business at the same time. These mistakes are super common, and honestly, most of them happen because you're busy focusing on what you do best (running your business!), not because you're bad at bookkeeping.
