How Construction Accounting Differs from Standard Accounting
Traditional accounting focuses on company-wide income/expenses; construction accounting drills down to each job. It must reflect how work is billed and recognized over time, not all at once.
- Job costing by project, phase, and cost code
- WIP tracking for in-progress jobs and backlog
- Special billing: AIA/progress, T&M, stored materials
- Retainage and change orders baked into billing and GL
Core Components of Construction Accounting
Use a consistent structure so labor, materials, subs, and equipment roll up accurately for each project.
- Cost codes & SOV to categorize work and align with billing
- Job costing for labor, materials, equipment, and subs
- Time tracking tied to jobs/phases for labor cost accuracy
- AP/AR workflows that respect retainage and partial payments
Revenue Recognition & Billing Methods
Because projects span weeks to months, revenue is recognized over time using billing methods that match progress.
- Percentage-of-completion via AIA/progress billing
- Time & Materials (T&M) based on actual hours and parts
- Stored materials billed before installation with documentation
- Retainage withheld and released at milestones/closeout
Key Financial Reports Contractors Should Track
Stay on top of profitability and cash by reviewing WIP and job-level performance routinely.
- WIP report: over/under-billing and earned revenue
- Job cost to complete: forecasted cost and margin at finish
- Labor cost report: burdened hours by job/phase
- AR aging with retainage: cash flow outlook by project
Common Construction Accounting Challenges
Manual spreadsheets and disconnected tools create errors that hurt margins and delay payments.
- Mismatched SOV/cost codes between field, billing, and books
- Lost labor hours or materials due to poor tracking
- Retainage and change order math errors
- Double entry between project system and accounting
How Software (Werx + QuickBooks) Simplifies the Workflow
Werx connects estimating, billing, time tracking, and payments—then syncs to QuickBooks Online to keep the GL clean and reduce rework.
- Create SOVs and generate AIA/progress billing with retainage
- Manage T&M billing with real-time labor and materials
- Capture field time via the Werx Field App to improve job costing
- Sync to QuickBooks integration for contractors to eliminate double entry
Also streamline cash collection with online payment processing for contractors.
FAQs About Construction Accounting
Do I need specialized construction accounting software?
You need job-costing and construction billing features. Many contractors pair Werx for project/billing workflows with QuickBooks Online for the GL, synced so data stays accurate.
What’s the difference between job costing and cost codes?
Job costing is tracking all costs to a project; cost codes categorize those costs (labor, materials, phase) so you can compare budget vs. actual and bill precisely.
Which revenue recognition method should I use?
Small contractors often start with completed-contract for simplicity; percentage-of-completion provides better visibility on longer jobs. Confirm with your CPA.
TL;DR Recap
- Construction accounting is project-based with job costing, WIP, and special billing
- Align SOV/cost codes, labor, and billing to protect margins
- Track WIP, job cost to complete, labor, and AR with retainage
- Werx + QuickBooks reduces errors and speeds cash collection
