Construction bookkeeping is one of the most complex and specialised areas of business accounting. Unlike a retail store or a software company, a construction business operates across multiple simultaneous projects, each with its own budget, cost codes, subcontractors, draws, and completion timeline. Standard bookkeeping methods fail construction companies — and the financial consequences can be severe.
The construction industry is also the second-largest sector for business failures in the United States, with poor financial management consistently cited as a leading cause. Accurate, construction-specific bookkeeping is not just a compliance necessity — it is a survival tool.
This guide by Entelyglobal explains what construction accounting and bookkeeping for construction companies involves, why it matters, how to do it right in 2025, and what it costs to outsource it to specialists.
What Is Construction Accounting?
Construction accounting (also called construction project accounting or job cost accounting) is a specialised form of financial recordkeeping tailored to the unique operational structure of the construction industry. It differs from standard accounting in several key ways:
- Revenue is recognised by project, not by period — using the percentage-of-completion or completed-contract method
- Costs are tracked at the job level, broken into labour, materials, subcontractors, and equipment
- A construction chart of accounts is structured differently to service or retail businesses
- Cash flow management is tied to draw schedules, retainage, and milestone billing
- Compliance requirements include certified payroll (Davis-Bacon), lien waivers, and bonding reports
Understanding what construction accounting is — and what makes it different — is the first step to getting your finances under control as a contractor or construction business owner
Construction Bookkeeping vs General Bookkeeping: Key Differences
Area | General Bookkeeping | Construction Bookkeeping |
Revenue recognition | Period-based (monthly) | Project-based (% complete or completed contract) |
Cost tracking | Category-level | Per-job cost codes (labour, materials, subs) |
Invoicing | Standard invoices | AIA draw schedules, progress billing, retainage |
Payroll | Standard payroll | Certified payroll, prevailing wage, multi-state |
Reporting | P&L, Balance Sheet | Job cost reports, WIP schedules, project profitability |
Software needs | QuickBooks, Xero | QuickBooks Construction, Sage 100, Procore, CoConstruct |
Many construction businesses make the costly mistake of using a general bookkeeper or generic accounting software for their construction finances. Without construction-specific accounting methods, job costs get misallocated, billing errors go undetected, and WIP (work in progress) is consistently misstated on the balance sheet.
Core Elements of Bookkeeping for Construction Companies
Job Costing
Job costing is the heart of construction accounting. Every dollar of labour, material, subcontractor, and equipment cost must be assigned to a specific project and cost code. Accurate job costing answers the most critical question in any construction business:
Without precise job costing, construction companies routinely underbid future projects, fail to identify problem jobs early, and lose money without knowing where it went.
Work In Progress (WIP) Schedules
A WIP schedule is a monthly or quarterly report that shows the financial status of every active project. It calculates overbilling (where you have billed more than you have earned) and underbilling (where you have earned more than you have billed). Accurate WIP reporting is essential for bonding, bank financing, and investor trust.
Progress Billing and Retainage
Construction projects are typically billed in stages (draws) based on percentage of completion, not on delivery of a finished product. Retainage — usually 5–10% held back until project completion — must be tracked separately on both the accounts receivable and accounts payable sides.
Construction Chart of Accounts
A construction chart of accounts is the backbone of your financial reporting system. It must include specific accounts for direct job costs (labour, materials, subcontractors, equipment), indirect costs, overhead allocation, retainage receivable, retainage payable, and contract revenue. Getting this structure right from the start avoids painful restatements later.
Certified Payroll and Prevailing Wage
For government-funded projects subject to Davis-Bacon regulations, construction payroll must meet prevailing wage requirements and be reported on certified payroll forms (WH-347). This adds significant complexity that most standard payroll providers cannot handle.
Common Bookkeeping Mistakes Made by Construction Contractors
Even experienced contractors fall into costly bookkeeping traps. These are the top bookkeeping mistakes of construction contractors that Entelyglobal ‘s specialists see repeatedly:
- Mixing personal and business expenses — a cash flow and tax nightmare
- Not tracking job costs in real time — discovering losses only after project completion
- Using cash-basis accounting instead of percentage-of-completion — overstating or understating revenue
- Failing to account for retainage correctly — distorting both revenue and receivables
- Misclassifying subcontractors vs employees — triggering costly IRS penalties
- Ignoring WIP schedules — presenting inaccurate financial statements to banks and sureties
- Using QuickBooks without construction-specific setup — losing critical job cost visibility
How to Do Bookkeeping for a Construction Company: Step-by-Step
Whether you are setting up bookkeeping for a new construction business or cleaning up an existing mess, follow this process:
- Step 1 — Set up a construction-specific chart of accounts tailored to your trade (general contractor, subcontractor, home builder, specialty contractor)
- Step 2 — Choose the right accounting software (QuickBooks for Contractors, Sage 100 Contractor, Buildertrend, or Procore for larger operations)
- Step 3 — Implement job costing from day one — assign every transaction a project code and cost type
- Step 4 — Set up progress billing templates based on AIA G702/G703 forms or your contract structure
- Step 5 — Reconcile all bank and credit card accounts monthly — never skip a month in construction
- Step 6 — Prepare WIP schedules monthly to monitor overbilling and underbilling across all active jobs
- Step 7 — Run job cost reports weekly — compare actual costs to estimated costs and flag variances early
- Step 8 — Manage subcontractor compliance: W-9 forms, COI tracking, and 1099-NEC filing at year end
QuickBooks for Construction: Setup and Limitations
QuickBooks for Construction (using QuickBooks Online Advanced or QuickBooks Desktop Contractor Edition) is one of the most widely used accounting platforms among small-to-mid-sized construction companies. However, properly setting it up for a construction business requires specialized configuration that most general bookkeepers are not familiar with.
Key QuickBooks construction setup requirements include:
- Enabling job costing and class tracking
- Building a construction-specific chart of accounts
- Setting up service items so they correctly map to income and cost of goods sold (COGS)
- Configuring progress invoicing for AIA-style billing
- Integrating with field management tools such as Procore, Buildertrend, and CoConstruct
QuickBooks construction pricing (2025):
QuickBooks Online Advanced (required for full construction functionality) starts at $235/month. QuickBooks Desktop Contractor Edition is available as either a one-time purchase or an annual subscription.
Many construction companies work with specialized firms like Entelyglobal to handle setup, ongoing bookkeeping, and monthly reporting—often more efficiently than hiring and managing an in-house part-time bookkeeper.
Construction Bookkeeping Software: Choosing the Right Platform
Software | Best For | Key Construction Features |
QuickBooks Online Advanced | Small–mid contractors | Job costing, progress billing, payroll |
Sage 100 Contractor | Mid–large GCs | Full WIP, certified payroll, bonding reports |
Procore (accounting module) | Large GCs | Project-level financial control, integrations |
Buildertrend | Home builders / remodelers | Budget tracking, client billing, scheduling |
Foundation Software | Specialty contractors | Union payroll, equipment costing, AIA billing |
Xero + Hubdoc | Small subs / sole traders | Basic bookkeeping, receipt capture |
There is no single best bookkeeping program for construction companies — the right choice depends on your revenue, number of active jobs, payroll complexity, and reporting needs. Entelyglobal works across all major platforms and can advise on the optimal setup for your business size and trade.
Construction Accounting for General Contractors vs Subcontractors
The bookkeeping needs of a general contractor (GC) differ significantly from those of a specialty subcontractor. Here is how:
General Contractors
- Manage multiple subcontractors with lien waiver tracking and 1099 compliance
- Require AIA-style progress billing and owner draw schedules
- Need bonding reports (prequalification financials) for surety relationships
- Track retainage payable to subs and retainage receivable from owners separately
Specialty Subcontractors (Electrical, Plumbing, HVAC, etc.)
- Focus on accurate time and materials billing or fixed-price job tracking
- Often subject to certified payroll on government and public-sector projects
- Need tight equipment cost tracking to ensure accurate job costing
- Must track insurance certificates and compliance documents for GC requirements
Accounting for Home Builders: Special Considerations
Home builders face a unique version of construction accounting that combines elements of both construction and real estate development. Key distinctions include:
- Inventory accounting for spec homes (homes built for sale, not under contract)
- Lot cost allocation across multiple units in a subdivision
- Sales tax treatment on materials varies by state and project type
- Revenue recognition can be delayed until closing — requiring careful WIP tracking
- Warranty reserves must be accrued and tracked separately
Entelyglobal serves custom home builders, production builders, and residential remodelers with tailored bookkeeping structures that match their business model.

Construction accounting is a specialised form of financial management designed for the project-based structure of the construction industry. Unlike regular accounting, it uses job costing to track costs per project, percentage-of-completion revenue recognition, WIP schedules, and construction-specific billing methods like AIA draw schedules.
Bookkeeping for a construction company requires setting up a construction chart of accounts, implementing job costing, using progress billing, preparing monthly WIP schedules, managing subcontractor compliance, and reconciling all accounts monthly. Most construction businesses benefit significantly from working with a construction-specialist bookkeeper rather than a generalist.
The most common mistakes include failing to track job costs in real time, not preparing WIP schedules, using cash-basis accounting instead of percentage-of-completion, misclassifying subcontractors as employees, and using generic bookkeeping software without construction-specific configuration.
For most contractors and construction companies, outsourcing bookkeeping is more cost-effective, more accurate, and more reliable than hiring in-house.
The best bookkeeping software for a construction company depends on your size and complexity. QuickBooks Online Advanced or QuickBooks Desktop Contractor Edition suits most small-to-mid-size contractors. Sage 100 Contractor is preferred by larger general contractors. Buildertrend and CoConstruct are popular among home builders and remodelers.
Setting up QuickBooks for a construction company requires enabling job costing and class tracking, building a construction-specific chart of accounts, configuring service items to map to cost of goods sold, setting up progress invoicing, and ideally integrating with your project management software. Entelyglobal offers QuickBooks construction setup as a standalone service.
A WIP (Work In Progress) schedule is a monthly report that shows the financial status of every active construction project — specifically whether each job is overbilled or underbilled relative to its percentage of completion. Banks, sureties, and investors require accurate WIP schedules to assess a contractor’s true financial health.
