QuickBooks for Contractors: What to Track Every Month

QuickBooks Online is the primary accounting platform for most small and mid-size contractors. It is accessible, it integrates with your bank and credit card accounts, and it has the tools you need to keep accurate records and get ready for tax season.

Here are the essentials contractors should track in QuickBooks every month, and why each one matters.

The foundation: your chart of accounts

Every transaction in QuickBooks flows through your chart of accounts, the system that categorizes all of your financial activity. For contractors, the default QuickBooks Online setup is a starting point, not a finished one. It needs customizing to match how your business actually works.

Essential expense categories should include:

• Materials and supplies (direct job costs, not office supplies)
• Subcontractor labor (separate from your own employees)
• Equipment rental
• Permits and inspections
• Direct labor (wages tied to specific jobs)

These are your cost of goods sold: the direct expenses of doing the work. Everything else is overhead. Keeping these categories clean is what makes your gross margin meaningful. Lumping subcontractor payments and office supplies into generic miscellaneous categories produces a misleading P&L.

The monthly tracking checklist

Every month, your QuickBooks should show you:

• Bank and credit card reconciliation. Every account balanced against your statements. This is non-negotiable. Without it, you do not really know your cash position.
• Open invoices and AR aging. How much customers owe you, and how old it is. Anything over 45 days needs a follow-up. Anything over 90 days needs a conversation.
• Open bills and AP. What you owe vendors and subs. Staying current with subcontractors keeps your relationships strong and your lien exposure low.
• P&L for the month. Revenue, direct costs, gross margin, overhead, net income. This is your monthly scorecard.
• Balance sheet. What you own, what you owe, and what is left. Check it monthly even if you do not fully analyze it. It catches problems the P&L misses.

The features most contractors underuse

Job costing (Projects in QuickBooks)

The Projects feature lets you assign revenue and expenses to a specific job. Set up properly, it produces a profitability report for each individual project, so you can see whether a job made money, not just whether the business as a whole did. It is the most valuable feature for contractors and the most neglected. The setup takes effort, but once it is running it changes how you bid.

Class tracking

Contractors who do more than one type of work, whether residential, commercial, or service, can use Classes to separate their financial reports by category. That shows you how gross margin differs across work types. For a business that mixes project work with service calls, it often reveals that one side is subsidizing the other.

Recurring transactions

Predictable expenses like insurance premiums, software subscriptions, and equipment payments should be set up as recurring transactions. It reduces bookkeeping work, makes sure nothing gets missed, and keeps your overhead categorized consistently.

1099 tracking

QuickBooks Online has built-in 1099 tracking for subcontractors. Any subcontractor you pay over $600 in a year needs a 1099-NEC. When you mark vendors as 1099 contractors through the year, QuickBooks can generate the forms automatically. Most contractors skip this setup and pay for it with a January scramble.

The most common QuickBooks mistakes contractors make

Using cash basis when accrual is more accurate

QuickBooks Online lets you switch between cash and accrual reporting. Most small contractors pick cash basis for simplicity, but accrual gives you a clearer view of job profitability, especially on larger projects that span several months.

Not reconciling every month

Books that have not been reconciled in three months or more produce unreliable statements. This is the most common issue in books that have not been kept current, and the easiest to fix with consistent discipline.

Letting the chart of accounts become a dumping ground

Over time, accounts pile up. A one-off transaction prompts a new category that never gets used again. You end up with far more accounts than you need. Good bookkeeping means reviewing and pruning your chart of accounts once a year.

The goal isn't perfect QuickBooks mastery. The goal is books you can trust, reviewed every month, that tell you something useful about your business.

When to get help

You do not need to become a QuickBooks expert. You need someone who keeps your books clean, properly categorized, and reconciled every month, and who can translate what they find into plain language.

Most contractors do not have that combination. Not the bookkeeping itself, but the interpretive layer: understanding what the numbers say about the actual business.

BooksSteady handles the QuickBooks work every month, then delivers a plain-language summary: what changed, what needs attention, and what to do about it. No jargon, delivered on a set date every month.

The bottom line

QuickBooks is a powerful tool that many contractors run like a basic checkbook. Set up properly and reviewed monthly, it gives you a real understanding of job profitability, cash position, and overall business performance.

That level of visibility is what separates contractors who grow on purpose from those who just stay busy and hope the numbers work out. The numbers reward attention. Most contractors do not give them any.
