How is construction bookkeeping different?

Despite construction accounting, like all accounting in other industries, having to be built on standard accounting principles, the unique way of construction company operation strikes various challenges and makes construction accounting more complex and difficult.

In addition to standard processes and procedures like accounts payable, accounts receivable, and payroll, construction companies deal with job costing, progress billings, change orders, retainage management, customer deposits, and other anomalies.

Below are the key factors in which construction accounting and bookkeeping differ from other types of accounting.

Cost of Goods Sold (COGS)

Cost of goods sold is any costs that are associated with the performance and completion of a project. However, COGs in construction are much more complex than in other brick-and-mortar stores. This includes a wide range of cost types you have to identify and categorize properly. Typically, a contractor or subcontractor often provides a wide range of services - everything from design, engineering, and labor. Thus, tracking different types of costs can be tricky and cause a lot of headaches.


Overheads consist of necessary, ongoing expenses, including the cost of subcontractors, machinery, equipment, insurance, office staff, office supplies, vehicles, and other costs. Since many such expenses in construction are attributed to specific construction projects, other businesses would consider overhead often fall into the COGs category for construction companies.

Project-base work

Contractors often work on and manage multiple projects at once - all of which are in different stages of progress. The payment process for each project is also different. There may be an upfront deposit required, the project could be paid in full, or take months before getting full payment. For these reasons, construction companies may need to generate separate profit and loss statements for each project. Therefore, the accuracy of bookkeeping and accounting plays a crucial role in giving a full insight into their financial health and support to making informed business decisions.

Unlike product sales, where companies recognize revenue when a widget is sold, bookkeeping and accounting in construction have different ways when it comes to revenue recognition.

Cash vs accrual accounting

Cash basic accounting means that revenue and expenses are recognized on the income statement only when cash is received. In other words, payables aren’t recorded until a check is written to pay bills, and the revenue isn’t recorded until payment is received and deposited into the company’s account.

The cash method is mostly used by small businesses because the financial statements closely reflect their cash position and the bookkeeping process is much easier and cheaper. In addition, under cash-basis accounting, a business doesn’t have to pay taxes on cash it hasn’t been collected. Despite its simplicity, cash accounting isn’t accepted by GAAP, and the resulting financial statements are considered distorted and insufficient about the company’s financial overview health.

Cash accrual accounting recognizes expenses and revenue in the time they are incurred before any money changes hands. The advantage of the accrual method is that it includes accounts receivables and account payables, as a result, provides a more accurate picture of the profitability of a company. The accrual is the most common method used and also a standard method under GAAP acceptance.

Percent Complete vs Completed Contract Income Recognition

The percentage completion vs completed contract is often used by construction companies because they typically work on long-term large projects in which income and expenses are often deferred. Accordingly, both percentages of completion and completed contract methods allow for such tax deferral.

The Percentage of Completion Method (PCM) that are used to recognize revenues, expenses, and taxes over the life of the construction contract based on its completion percentage. For example, if the contract is 50% complete then the contractor will recognize half of the revenues, costs, and income.

The Completed Contract Method (CCM) allows for the recognition of revenues, expenses, and taxes once a project is complete. Because revenue is recognized after expenses and revenue have occurred, this method of income recognition is not GAAP-approved.
