The default categories in QuickBooks aren’t built for trades businesses. They’re generic, and using them as-is means your reports won’t tell you anything useful about where your money actually goes. The first thing to do is customize your chart of accounts so it reflects how your business operates.

Start by separating direct job costs from overhead. Direct job costs are expenses tied to a specific job or customer. Materials you buy for a project, subcontractor payments, permit fees for a job, and equipment rentals for a specific project all fall here. These should sit under Cost of Goods Sold (COGS) in QuickBooks. Overhead is everything else that keeps the business running regardless of whether you have a job that week.

For a typical skilled trades business, your direct cost categories should include job materials, subcontractor labor, permit and inspection fees, and equipment rental. Keep materials separate from subcontractors because they behave differently and you need to see each one clearly when reviewing profitability.

On the overhead side, set up categories that match your actual spending patterns. Vehicle expenses should have their own category since trucks and vans are a major cost for trades businesses. Break it into fuel, repairs and maintenance, and insurance if you want more detail, or keep it as one line if you track mileage using the standard rate. Tools and small equipment under $2,500 can be expensed directly. Larger equipment purchases get recorded as assets and depreciated.

Insurance deserves its own attention. General liability, workers comp, and commercial auto are all different types of coverage and your accountant will want them separated at tax time. Don’t lump them into one “insurance” line if you can avoid it.

Other common overhead categories include phone and internet, advertising, office supplies, licensing fees, professional fees, and bank or merchant fees. If you pay for uniforms, safety gear, or trade association memberships, those each deserve a line or at least a subcategory.

The biggest mistake is using “miscellaneous” or “uncategorized expense” as a catch-all. Every dollar that lands there is a dollar your accountant has to research later or a deduction that might get missed entirely. If you’re not sure where something goes, flag it and ask. That’s better than guessing wrong or hiding it in a junk drawer category.

When you code expenses, do it the same day or at least the same week. The longer you wait, the harder it is to remember what a $247 charge at a supply house was for or which job it belonged to. Consistency matters more than perfection. A Long Beach bookkeeper who understands trades work can review your categorization monthly and fix small errors before they compound into a mess at year end.

If your QuickBooks file has been running on default categories for a while, it’s worth cleaning it up now rather than waiting. Reclassifying a few months of transactions is much easier than untangling two years of bad data when your tax return is due.
