The Top 10 Expense Categories Every Small Business Should Track

One of the fastest ways to make bookkeeping easier is to simplify your categories.The goal isn’t to create 80 categories, it’s to create clean reporting you can actually use.

If your categories are consistent month to month, you can quickly answer:

• Where is my money going?

• What costs are growing?

• What can I cut without hurting revenue?
  

The 10 most useful expense categories (for most small businesses)

1) Advertising & marketing

Includes: Google/Facebook ads, website costs, SEO tools, printing, Canva, and promos.

Tip: If you run ads, consider keeping ads separate from “software” so you can track ROI.

2) Software & subscriptions

Includes: QuickBooks, Gusto, Wix, Calendly, email tools, and industry software.

Tip: Review these quarterly, as subscriptions can quietly grow.

3) Office supplies

Includes: small supplies, postage, printer ink, and basic office purchases.

Common mistake: putting big purchases here (those often belong in equipment).

4) Professional services (CPA, legal, bookkeeping)

Includes: tax prep, legal consults, bookkeeping, payroll support.

Why it matters: This category often signals “we’re scaling” and can be a great investment.

5) Insurance

Includes: business insurance, general liability, professional liability (E&O).

6) Meals (business-related)

Includes: client meals, team meals, business meetings (when applicable).

Best practice: keep a note (who + purpose). Ask your CPA about what’s deductible in your situation.

7) Travel

Includes: airfare, hotels, ride share, parking, and business trips.

Tip: Travel is where documentation matters most—save receipts and note the business purpose.

8) Repairs & maintenance

Includes: equipment fixes, office repairs, and routine maintenance.

9) Phone & internet

Includes: business phone line, internet, mobile plan (if used for business—confirm specifics with your CPA).

10) Merchant processing fees

Includes: Stripe/PayPal/Square fees, card processing fees.

Tip: If fees are netted out (you only see deposits), make sure you’re still capturing the fees somewhere so profit is accurate.

Bonus: categories that get mixed up all the time (and how to fix it)

Owner draws vs payroll

• Owner draw = taking money out as an owner

• Payroll = wages paid (usually with payroll reporting)
  

If this is wrong, your reports can look “off” fast.

Business mileage vs travel

• Mileage = local driving for business

• Travel = trips (hotel/airfare)Keep them separate so your CPA has clean numbers.
  

Supplies vs equipment (big purchases)

A simple rule:

• Supplies = smaller, routine purchases

• Equipment = bigger items used over time (laptops, cameras, machinery)

(Your CPA can advise what should be expensed vs capitalized.)

Quick win (do this today)

Pick 10–15 categories max and stick with them for 90 days.

Consistency beats perfection. You can always refine later, but switching categories every month makes reporting useless.
