How to Track Business Expenses

Most small businesses don't lose track of expenses because they're careless — they lose track because there's no simple habit for logging them as they happen. The fix isn't more sophisticated software; it's a running log that takes thirty seconds to update.

What to log for each expense

  • Date. When it happened, not when you got around to logging it.
  • Category. Supplies, travel, software, marketing — whatever groupings actually match how your business spends.
  • Description. Specific enough that you'd recognize it months later.
  • Amount. The actual number, logged immediately rather than reconstructed from memory later.

Why categories matter more than the total

Knowing you spent $9,100 last month tells you less than knowing $5,000 of it was payroll and $600 was marketing. The total is a number; the categories are what let you actually decide what to change.

Log it when it happens, not at month-end

A running log updated in real time is accurate. A reconstruction attempted at the end of the month from memory and a pile of receipts usually isn't — and it's the habit, not the tool, that determines which one you end up with.

Use the template instead of building this from scratch

The Expense Tracker Template has this exact structure already built, with the total calculating automatically as you add rows. Open it in FLYNT Sheets and start logging — pair it with the Small Business Budget Template to see actual spending against your planned budget.
