How to track business expenses without QuickBooks

QuickBooks is the default answer when someone asks how to track business expenses. But for a lot of small trades businesses, it’s overkill. You’re paying $30/month for a tool that was designed for accountants, not for someone who’s under a sink six hours a day.

Here’s the thing: you absolutely need to track expenses. The IRS doesn’t care that you were busy. But you don’t need QuickBooks to do it.

Why expense tracking matters

If you’re a sole proprietor or small LLC, every business expense you track reduces your taxable income. Miss $5,000 in deductible expenses and you could owe an extra $1,000 to $1,500 in taxes depending on your bracket. That’s real money you’re leaving on the table.

Common deductible expenses for trades businesses include:

• Vehicle costs (mileage or actual expenses)
• Tools and equipment
• Materials and supplies
• Insurance premiums
• Phone and internet (business portion)
• Software subscriptions
• Licensing and certification fees
• Subcontractor payments

The shoebox method doesn’t work

We all know someone who tosses receipts in a shoebox and hands it to their accountant in April. This approach loses receipts, misses deductions, and makes tax time miserable. Your accountant charges you more because they’re doing detective work instead of filing.

What to do instead

The best expense tracking system is the one you’ll actually use. For most trades business owners, that means something on your phone that takes less than 30 seconds.

Option 1: A dedicated app. Apps like Expensify or Dext let you snap a photo of a receipt and categorize it. They work well but they’re another subscription and another app to manage.

Option 2: A spreadsheet. Google Sheets works fine if you’re disciplined. Create columns for date, vendor, amount, category, and notes. Update it weekly. The problem is that most people stop updating it by February.

Option 3: Built-in expense tracking. This is what we built into FieldFlow. Since you’re already in the app to schedule jobs and send invoices, you can log expenses in the same place. Snap a photo of a receipt, categorize it, and it shows up in your profit and loss view. No extra app, no extra subscription.

Tips for staying on top of it

1. Log expenses the same day. Don’t tell yourself you’ll do it later. Take 20 seconds when you’re still at the supply house.
2. Use categories consistently. Pick 8-10 categories and stick with them. Don’t overthink it.
3. Separate business and personal. Get a business credit card or bank account. It makes everything cleaner.
4. Review monthly. Spend 15 minutes at the end of each month scanning for anything you missed.
5. Share access with your accountant. Whether it’s a spreadsheet or an app, give your accountant view access so they can pull what they need at tax time.

When you do need QuickBooks

If you have more than 10 employees, carry inventory, or have complex payroll, QuickBooks or Xero probably make sense. But for a 1-5 person trades business? You can get by with something much simpler — and save $360/year in the process.
