Start with separate accounts. Open a business checking account and get a business credit card. Every dollar that comes in goes to the business account. Every business expense goes on the business card. This separation makes bookkeeping dramatically easier and keeps you out of trouble if you’re ever audited.

Track all income, especially cash. Handyman work often involves cash payments, and it’s tempting to pocket them without recording anything. That’s how you underreport income and create problems with the IRS. Deposit cash payments into your business account and record them just like checks or card payments. If a customer pays $150 cash for a garbage disposal install, that income exists whether you record it or not.

Log your mileage every day. Handymen drive constantly. You might hit three or four jobs across town in a single day. The standard mileage deduction adds up fast when you’re putting serious miles on your truck. Use an app like MileIQ or even a simple notebook in your vehicle. Record the date, starting location, destination, and business purpose. Trying to recreate a year of mileage at tax time doesn’t work.

Categorize expenses into groups that matter for taxes. Common categories for home services businesses include tools and equipment, materials and supplies, vehicle expenses, insurance, phone and communication, advertising, and professional services. When you buy a new drill at Home Depot, that’s tools. When you buy pipe fittings for a job, that’s materials. Getting the category right means the expense lands in the right place on your tax return.

Materials purchased for specific jobs should be tracked to those jobs if possible. Even basic job tracking helps you understand which types of work are profitable. If you’re consistently losing money on plumbing calls because materials eat up the labor charge, you need to know that. You don’t need complicated software for this. A spreadsheet with job name, revenue, and material cost tells you a lot.

Keep receipts for everything. Take a photo with your phone immediately after a purchase. Paper receipts fade and get lost in your truck. Digital photos organized by month or saved to an app survive and are searchable. Your accountant will thank you at tax time.

Pick software that matches your complexity. A solo handyman with straightforward finances can use Wave, which is free, or simple QuickBooks Self-Employed. If you have employees, multiple trucks, or want more detailed reporting, QuickBooks Online makes sense. The software matters less than actually using it consistently.

Set aside time weekly to update your books. Fifteen minutes every Friday to categorize transactions, record cash payments, and check your mileage log. Letting it pile up for months means you forget what charges were for and spend hours reconstructing instead of minutes maintaining.

Set aside money for taxes. Handymen are typically self-employed, which means quarterly estimated tax payments. A common approach is moving 25-30% of every payment into a separate savings account dedicated to taxes. When quarterly payments come due, the money is already there.

If bookkeeping feels like more than you can handle while running jobs, that’s normal. Many handymen work with a bookkeeper in American Fork or nearby who handles the monthly categorization and reconciliation. You focus on the work, they focus on the books, and your accountant gets clean records at year end.
