Contractors are usually good at knowing whether the crew is busy. The harder question is whether each job is producing the margin the business needs.
A healthy bank balance can hide unpaid material bills. A profitable month can hide one job that lost money. A large customer payment can make cash look strong even when payroll, sales tax, loan payments, and vendor checks are already spoken for.
That is why useful construction bookkeeping goes beyond categorizing transactions. It connects the books to the way the work is estimated, scheduled, completed, billed, and collected.
For contractors and skilled-trade businesses in Wichita and across South Central Kansas, the following eight numbers create a practical starting point. You do not need a complicated reporting package on day one. You do need a consistent process that lets you trust what you are seeing.
Revenue by job
Total sales tell you how large the business is. Revenue by job tells you which projects are building it.
Every invoice, progress billing, change order, and customer deposit should be associated with the correct customer and project. That creates the revenue side of a job-profitability report and makes it easier to compare the final result with the original estimate.
This becomes especially important when several jobs are active at once. Without project-level revenue, a strong project can cover up a weak one and make the overall month look acceptable.
The goal is not to create more paperwork. It is to answer a basic operating question: What did this specific job earn?
Direct materials
Lumber, concrete, pipe, wire, fixtures, paint, steel, parts, and other materials should follow the job whenever practical.
A charge sitting in a broad “materials” account may be correct for the financial statements, but it does not help you understand whether Project A or Project B was priced properly. Consistent job names on purchase orders, receipts, vendor bills, and credit-card transactions make the accounting much more useful.
Tracking material cost by job also helps expose purchasing problems, waste, theft, rework, or estimate assumptions that no longer match current prices.
For small trade businesses, consistency matters more than perfection. Start with the material categories that have the largest effect on the bid and build from there.
Direct labor and labor burden
Hourly wages are only part of what labor costs the business.
Depending on the company and the work, the true cost may also include employer payroll taxes, workers’ compensation, benefits, paid time off, and other labor-related expenses. That combined cost is often called labor burden.
If a bid assumes that a technician costs the company only the hourly wage, the job can look profitable on paper while producing a much smaller margin in reality.
Time also needs to be assigned consistently. Field hours belong to jobs; office, sales, training, and general shop time are usually overhead. A clean payroll process makes this distinction easier and supports better project reporting. Learn more about connected payroll and compliance support.
Subcontractor costs
Subcontractors can make a job possible without adding permanent payroll, but their costs still need to land on the right project.
Keep vendor names, invoices, payment details, and required tax information organized throughout the year. Contractor classification and reporting depend on the facts, so questions should be addressed when the relationship begins rather than during January cleanup.
From a management perspective, the important number is straightforward: how much outside labor or specialty work did the job require, and was that cost included in the estimate?
When subcontractor invoices are entered late or coded only to a general expense account, job margin can look better than it really is until weeks after the work is complete.
Equipment cost and debt
Trucks, trailers, skid steers, mowers, lifts, welders, and specialized tools affect profit and cash in different ways.
The purchase itself may create an asset on the balance sheet. A loan creates a liability. Principal and interest are not the same expense. Fuel, repairs, insurance, registration, and downtime are separate operating costs.
If equipment is a major part of the work, owners should know more than the monthly payment. Useful questions include:
- What does the equipment cost to own and operate?
- How many productive hours does it generate?
- Is the cost included in job pricing?
- Will upcoming repairs or replacements create a cash squeeze?
- Does buying another unit improve capacity enough to support the payment?
Clean fixed-asset and loan records are also part of maintaining reliable monthly books and tax-ready information.
Gross profit by job
This is where the pieces come together.
Job gross profit is generally job revenue minus the direct costs required to complete that work. The exact categories should match how the company estimates and operates, but the report commonly includes materials, direct labor and burden, subcontractors, equipment, and other project-specific costs.
The dollar amount matters. The percentage matters too.
A $10,000 gross profit on a $25,000 job is very different from a $10,000 gross profit on a $100,000 job. Comparing margin percentages across similar projects can reveal which customers, services, crews, or job types deserve more attention.
It also closes the loop between estimating and accounting. If estimated margin and actual margin repeatedly differ, the business can investigate labor hours, material assumptions, change orders, waste, callbacks, and overhead recovery before bidding the next job.
Our accounting support for construction and trades is designed around that operating reality.
Accounts receivable aging
Profit does not pay payroll until the customer pays the invoice.
An accounts receivable aging report groups unpaid invoices by how long they have been outstanding. It helps the owner separate normal open invoices from balances that are becoming a collection problem.
Reviewing the report consistently can surface:
- Invoices that were never delivered or received
- Missing approvals, lien waivers, or other documentation
- Change orders that were completed but not billed
- Retainage that needs follow-up
- Customers who routinely pay outside agreed terms
- Large balances that create concentration risk
The best collection process usually starts before an invoice is late: clear terms, complete documentation, prompt billing, and regular follow-up.
Committed cash
The checking-account balance is only the starting point.
Committed cash is the portion already needed for known obligations such as payroll, payroll taxes, vendor bills, subcontractors, loan payments, sales tax, insurance, and materials for upcoming work.
Separating available cash from committed cash gives the owner a more realistic view of what can be used for equipment, hiring, owner distributions, or growth.
A short cash forecast can be more valuable than a complicated annual budget. Start with the next four to eight weeks: expected collections, payroll dates, large purchases, debt payments, taxes, and unusual expenses. Update it as the schedule changes.
For businesses with uneven project timing, this kind of cash-flow reporting and advisory support can turn the accounting system into a planning tool.
A practical monthly review for a trade business
The reports only help if someone reviews them and follows up on what looks unusual. A useful monthly process can stay relatively simple:
- Reconcile every bank and credit-card account.
- Review uncategorized and owner-related transactions.
- Confirm that project revenue and direct costs were assigned to the right jobs.
- Review unpaid customer invoices and overdue vendor bills.
- Compare estimated and actual margin on completed or substantially complete jobs.
- Check payroll, tax, debt, and equipment balances.
- Look ahead at cash needed for the next several weeks.
- Write down the two or three decisions the numbers point to.
The final step is the one most often missed. Accounting should produce action: follow up on an invoice, update a labor assumption, change how equipment is priced, tighten change-order approval, or decide whether the next hire is affordable.
When basic bookkeeping is enough, and when it is not
A one-person trade business with a small number of transactions may only need clean monthly bookkeeping, a dependable tax process, and a simple view of cash.
As the business adds crews, equipment, payroll, subcontractors, multiple active jobs, financing, or larger contracts, the reporting usually needs to become more detailed. That does not mean every contractor needs a controller or a complex software stack. It means the bookkeeping process should grow with the decisions the owner has to make.
The right system is the simplest one that reliably answers the important questions.
Construction bookkeeping FAQ
What should a contractor track in bookkeeping?
At a minimum, contractors should separate revenue and direct costs by job, reconcile bank and credit-card accounts, track receivables and payables, record equipment and debt correctly, and review cash needed for payroll, taxes, vendors, and upcoming work.
How often should contractors review job costs?
Active jobs are usually most useful when reviewed at least monthly, and more frequently when projects are short, labor-intensive, or cash is tight. The right cadence depends on how quickly reliable field and vendor information becomes available.
Can QuickBooks track construction job profitability?
QuickBooks can support customer and project tracking when transactions, payroll, materials, and subcontractor costs are consistently assigned. The report is only as reliable as the process used to capture those costs.
When does a trade business need professional bookkeeping?
It may be time when the owner cannot keep the books current, job margins are unclear, tax season becomes a cleanup project, payroll or equipment adds complexity, or financial information is not reliable enough for hiring, pricing, or financing decisions.
