Small Business — Quick FAQ

What's the easiest way to do small-business bookkeeping without software?

A simple spreadsheet that logs income and expenses by category and totals your profit automatically — no monthly subscription and no accounting jargon. Our Small Business Bookkeeping template does exactly this in Google Sheets or Excel.

How much should I set aside for taxes as a small-business owner?

If you're self-employed, a safe default is 25–30% of your net (after-expense) income for federal self-employment plus income tax. Get your exact number with the free self-employed tax calculator.

Do I need accounting software or is a spreadsheet enough?

For a solo or early-stage business, a spreadsheet is usually plenty — it's cheaper and simpler. Move to software when bank-feed automation, payroll, or sales tax start saving more time than they cost. See our spreadsheet vs accounting software breakdown.
