Running a general contracting business means managing multiple jobs simultaneously — multiple crews, multiple subcontractors, multiple clients, multiple payment schedules, and multiple cost streams all running at the same time. Without robust bookkeeping systems, the financial picture of your business becomes a blur. You can’t tell which jobs are making money and which are losing it. You don’t know when cash will be tight. You can’t see subcontractor balances across projects. This guide covers the bookkeeping practices that general contractors need to manage multiple jobs without losing financial control.
The Core Challenge: Financial Visibility Across Multiple Projects
The defining challenge for a general contractor’s bookkeeping is that your business is actually a portfolio of mini-businesses (individual projects), each with its own budget, cost stream, billing schedule, and profitability. Managing them in aggregate — without project-level visibility — means you’re always reacting rather than managing. Profitable GC operations require seeing revenue, costs, and margins at the project level so you can identify which jobs are over budget, which are behind on billing, and which are most profitable — in real time, not at job close.
Setting Up QuickBooks for Multi-Job GC Operations
For a general contractor, QuickBooks setup is more complex than for a specialty trade. Your Chart of Accounts needs separate income categories for each contract type (residential remodel, commercial TI, new construction, etc.). More importantly, every job must be set up as a QuickBooks Project from day one. The Project tracks all revenue billed, all direct costs (labor, materials, subs, permits, equipment), and calculates your gross margin by project. The Projects dashboard gives you a real-time snapshot of all active jobs — their budget, costs to date, and profitability. This is your command center as a GC.
Managing Subcontractors in QuickBooks
Subcontractor management is the most complex bookkeeping challenge for general contractors. Best practices include: set up each sub as a Vendor in QuickBooks with their W-9 information, insurance certificate expiration dates, and CSLB license number; enter every subcontract as a purchase order in QuickBooks so you track committed costs against each project; enter all sub invoices as bills in QuickBooks and assign them to the correct project; pay subs only after verifying their lien release (conditional waiver when payment is issued, unconditional after it clears); and track 1099 totals throughout the year in QuickBooks so year-end 1099 preparation is automatic. At year-end, the 1099 report in QuickBooks shows all unincorporated subs paid $600+ — no manual calculation required.
Progress Billing and Draw Management
GC jobs with durations of more than a few weeks require progress billing — scheduled invoices tied to project milestones or completion percentage. In QuickBooks, use the Progress Invoicing feature to create invoices based on a percentage of the original estimate, specific line items completed, or a custom schedule. This ensures you’re billing at the right times and tracking how much you’ve billed versus how much you’ve completed — a critical metric for avoiding over-billing or under-billing situations. Track retainage receivable (amounts withheld by the owner) in a separate QuickBooks account so it appears clearly on your balance sheet.
Job Cost Variance Analysis
The most valuable analysis a GC can run is the cost variance report: actual costs to date versus budget for each active job, categorized by cost type (labor, materials, subs, equipment). Run this weekly during construction. Any variance over 10% in any category deserves investigation. Labor overruns early in a job often predict a money-losing project — address them immediately with crew efficiency discussions, scope adjustments, or change orders. Material overruns may indicate waste, theft, or incorrect material quantities in your original estimate — both need to be corrected. Catching variances early gives you the ability to course-correct. Catching them at job close doesn’t.
Cash Flow Management Across Multiple Jobs
Running multiple jobs simultaneously creates complex cash flow patterns. You might be mobilizing on a new job (cash out for materials and labor) while waiting for a progress payment on an older job. Maintaining a 13-week cash flow forecast — updated weekly — is the tool that gives GCs visibility into upcoming cash needs and surpluses. In QuickBooks, you can use the Customer and Vendor Center to see all outstanding receivables and payables by due date, giving you the inputs for a cash flow forecast. Maintain a revolving business line of credit as a backup for timing gaps — this is standard practice for growing GC operations.
Frequently Asked Questions
How do I track committed costs (subcontract obligations) in QuickBooks?
Use Purchase Orders in QuickBooks for each subcontract. Enter the full subcontract value as a purchase order assigned to the project. As the sub invoices you, enter each invoice as a bill against the purchase order. QuickBooks tracks the committed amount, the billed amount, and the remaining balance — giving you a complete picture of your cost exposure per sub per job.
How often should I reconcile my books as a GC with multiple jobs?
Bank reconciliation should happen monthly — every month, without exception. Job cost review (comparing actual to budget) should happen weekly during active construction. AR aging review should happen weekly. Full financial statement review should happen monthly. With a professional bookkeeper handling the month-end close, you can focus on the weekly operational reviews that drive project profitability.
