How to Track Business Expenses

The consulting firm owner handed me her credit card statement. Twelve charges she couldn't identify. Four subscriptions for tools nobody used. A $2,400 annual renewal that auto-processed three days earlier.

She wasn't careless. She ran a $1.8M business with seven employees. But expense tracking happened reactively - reconciling statements after money already left. By the time she noticed problems, the damage was done.

Over 18 months, we identified $47,000 in annual waste: duplicate subscriptions, unused services, and vendor charges that had crept up without review. That's 2.6% of revenue recovered through tracking expenses before they disappeared.

The Expense Tracking Problem

Most businesses track expenses for tax purposes. They categorize spending after it happens, file receipts, and hand everything to the accountant at year-end.

This approach catches nothing. By the time you see the problem, you've paid for it - often multiple times.

Effective expense tracking happens at three points: before spending (approval), during spending (categorization), and after spending (review). Miss any point and waste accumulates.

ACTION: Identify how many expense decisions happen without any approval process. That's your exposure.

Building Category Structure

Your expense categories should match how you think about costs, not how your accountant files taxes.

Useful categories:

• Payroll and benefits (your largest category)

• Rent and facilities

• Software and subscriptions (track individually, not as one lump)

• Professional services (legal, accounting, consulting)

• Marketing and advertising

• Travel and entertainment

Microsoft 365: $28/user × 7 = $196/month (used daily)

Slack: $12.50/user × 7 = $87.50/month (used daily)

Grammarly Business: $180/month (nobody remembers signing up)

Within 20 minutes, we found $379/month - $4,548/year - in subscriptions to cut or downgrade.

Timing: When to Track

Real-time tracking catches problems immediately. Monthly tracking catches problems within 30 days. Annual tracking catches nothing useful.

Daily tracking (for high-volume businesses):

• Enter every transaction same-day

• Categorize as you go

• Flag anything unusual for review

Weekly tracking (for most businesses):

• Batch process transactions each Monday

• Match receipts to charges

• Investigate unknowns before another week passes

Monthly tracking (minimum acceptable):

• Complete reconciliation by the 5th

• Compare against budget categories

• Address variances over 10%

ACTION: Set a recurring calendar block for expense tracking. Weekly is the right frequency for most businesses.

The Approval Workflow

Every expense should have an approval path, even if the path is just "owner reviews before payment."

Under $100: Pre-approved for operational needs

$100-500: Manager approval required

$500-2,000: Owner approval required
