How to Track Business Expenses Without Losing Your Mind
Most business owners don't lose money to one big mistake — they lose it to a hundred small expenses they never categorized, never deducted, and never reviewed. A simple expense tracking system pays for itself the first time you do your taxes.
What Counts as a Business Expense
The IRS standard: ordinary and necessary for your business. That includes software, mileage, contractor payments, office supplies, business meals (50%), travel, marketing, and a long tail of category-specific items.
The Three Levels of Tracking
Level 1: Manual
A spiral notebook or basic spreadsheet. Works if you have under ~20 transactions a month. Pros: cheap, simple. Cons: error-prone, no receipt storage, painful at tax time.
Level 2: Spreadsheet + Receipt Folder
A Google Sheets template with categories, plus a folder in Google Drive for scanned receipts. Add a column for the receipt link. Surprisingly effective for most solopreneurs.
Level 3: Dedicated App
A check-writing app with a register handles the cash side; an expense tracker (Expensify, QuickBooks Self-Employed) handles cards and receipts. The two together give you tax-ready records year-round.
Habits That Make It Work
- Snap every receipt the moment you get it
- Use one credit card and one checking account exclusively for the business
- Categorize weekly — never let it pile up past two weeks
- Reconcile monthly against bank and card statements
Common Categories to Track
- Software & subscriptions
