- Industry scope: Construction accounting applies specialized principles to track costs and revenues for individual projects, unlike general accounting which aggregates across operations. The construction sector accounts for a significant portion of GDP and requires precise financial management due to project-based cash flows and long durations.
- Revenue cycle: Construction revenue is typically recognized over time using percentage-of-completion or completed contract methods, depending on contract terms and project length. This differs from most industries where revenue is recognized at point of sale or delivery of goods.
- Cost accumulation: Costs are accumulated by project using job costing systems, which capture direct materials, direct labor, and allocated overhead. Accurate cost tracking is critical for profitability because each project is a unique profit center.
- Contract types: Common contract structures include fixed-price, cost-plus, and time-and-materials contracts. Each contract type affects revenue recognition timing and risk allocation between contractor and owner.
- Progress billing: Contractors bill clients periodically based on completion milestones or percentage of work completed. Progress billings generate accounts receivable that are tracked separately from general receivables.
- Retainage: Many construction contracts include retainage, where the owner withholds a percentage of each progress payment until project completion. This creates a unique asset or liability on the contractor's balance sheet.
- Change orders: Scope changes during construction require modifications to contract price and often lead to disputes. Change order accounting must capture additional costs and revenue adjustments separately from original contract amounts.
- Financial statements: Construction companies prepare standard financial statements (balance sheet, income statement, cash flow statement) but with added schedules for work-in-progress (WIP), backlog, and contract assets/liabilities.
- Lien waivers: Contractors issue lien waivers upon receiving payment to protect owners from mechanic's liens. Unconditional waivers release all rights, while conditional waivers apply only upon check clearance. Proper tracking of both types is essential to avoid duplicate payment and legal disputes, and waiver management must align with each progress billing and retainage release.
- Subcontractor accounting: General contractors manage payables to multiple subcontractors, often requiring certified payroll reporting on prevailing wage jobs. Costs from subcontractors are direct project costs, and payment release must be contingent on verified work completion and receipt of lien waivers to avoid financial and legal exposure.
- Overhead allocation: Indirect costs such as home office expenses, insurance, and equipment depreciation must be allocated to projects using a reasonable base like direct labor hours or total direct costs. Incorrect allocation can distort project profitability and lead to inaccurate bidding, making a consistent allocation method critical for financial integrity.
- Bonding and surety: Many construction projects require performance and payment bonds issued by surety companies to protect project owners. A contractor's bonding capacity depends on its financial strength, working capital, and past performance record. Bonding costs are project expenses that must be estimated upfront, and surety requirements influence cash flow management and the types of contracts a firm can accept.
