Glossary of construction accounting terms

Broadening financial knowledge is essential for any business owner. Understanding the key terms and concepts of construction accounting is a great place to start.

We’ve listed and defined the most important financial terms and concepts to strengthen both financial literacy and business acumen for contractors.

Financial assets

Asset

An asset is any resource with economic value owned or controlled by you. Assets can be either tangible (physical things like equipment) or intangible (non-physical things like your brand value or customer list).

Liability

On the other side of a balance sheet, opposite assets, liabilities reflect any legal responsibility to pay debts or fulfill contractual obligations; liabilities may include loans, accounts payable, bonds, deferred revenues, or other accrued expenses.

Cash

Cash is legal tender used to exchange goods or services. Any assets that can be easily converted to cash (like overnight money-market funds) can also be considered “cash” from a financial perspective. 

Construction Bond

A construction bond is a surety bond typically used to protect building owners. Given that a contractor’s inability to perform can result in significant delays (and therefore costs) to a project, a construction bond pays the owner if the if the bondholder (the contractor) triggers its provisions. Construction bonds are usually only seen on large projects or government projects.

Capital

Capital is anything that holds or can generate value; capital could be equipment/machinery, intellectual property, or financial assets. Any money or assets used to produce goods and services, or to fund investments, can also be defined as capital.

  • Debt capital – Any funding acquired through borrowing. 
  • Equity capital – Funding acquired through the sale of ownership in the company (usually in form of shares of common or preferred stock).
Accounts

Accounts payable

Accounts Payable, or A/P, describes money owed by one company to another for invoices that have been properly presented for payment. A/P is recorded on the balance sheet as a liability.

Accounts receivable

Accounts Receivable, or A/R, is money owed to a company by its customers for invoices that have been properly presented for payment. On a balance sheet, A/R is reflected as an asset.

Credit

Credit is the ability to access or borrow money, and in turn, take on debt, with the obligation to pay it back. Lenders, vendors, merchants, and service providers can all serve as creditors, granting credit to borrowers they determine capable of repayment.

Accounting principles

Generally Accepted Accounting Principles (GAAP)

Generally accepted accounting principles are standards and guidelines created by the Financial Accounting Standards Board. They are the basis for all accrual-based financial statements in the U.S.; all public companies in the United States are obligated to follow GAAP. GAAP aims to ensure consistency in accounting practices and financial reporting through a standard set of rules, procedures, and practices.

Job costing

Job costing is an accounting approach for allocating all the associated costs for a job to that job. The goal of job costing is to determine job-level (and even sometimes phase-level) profitability.

Income statement

Also referred to as a P&L, an income statement or profit and loss statement consolidates revenues, costs, and expenses generated for a specific period of time; many  income statements will display numbers for a quarter or fiscal year and are used to measure the financial success of business operations. Most income statements are presented on an accrual basis, which means that revenue is only recognized when earned and costs are matched to the associated revenue. Be careful though: while an essential accounting tool, an income statement won’t tell you how much cash your bank account increased or decreased by in a given period – cash flow can be impacted by items not reflected on an income statement!

Accrual accounting

Under accrual accounting, revenue is recorded when earned, not when the company collects the money. Likewise, costs are only recognized in the period when the associated revenue is recognized.

Financial analysis

Profit

Profit is defined as total revenue less total expenses. However, profit can be calculated and reported in various forms, such as: 

  • Gross profit (profit made after subtracting the direct costs associated with providing a good or service (aka, Cost Of Goods Sold, or COGS)
  • Operating profit (Operating Profit = Gross Profit – Operating Expenses)
  • Net profit (Operating Profit less interest and taxes, commonly referred as “bottom line”)

Profit margin

At a basic level, profit margin is operating or net profit (depending on the case)  divided by revenue; profit margin will display how many cents of profit is made per each dollar of revenue.

Markup

Markup is the additional amount of money added to the price of goods and services above the costs to the company for delivering those goods or services. It’s the gross profit you expect to earn.

Overhead

Overhead costs consist of any expenses that must be paid to keep a business up and running that are not directly related to the production of a good or service; these costs include rent, property tax, insurance, and licenses.

Contingency funds

A contingency fund is a lump sum of money set aside for unforeseen costs that may arise during a construction project.

Contracts

Change order

A change order is an amendment to a construction contract that changes or alters the scope of work. Most change orders will alter the timeline, budget, or work required; change orders can result in either an increase or a decrease in the overall price of the contract, but an increase is more common.

Cost-plus / Time & Materials

Cost-plus provide that the customer will pay the contractor for the expenses they incur to complete the project plus a defined fee or a specified percentage markup.

Guaranteed Maximum Price (GMP)

Guaranteed Maximum Price is a contractual obligation that sets a limit, or cap, on the amount of money a project owner is willing to spend on a project. This is usually included as language within a contract to help a project owner from over-paying and provides a mechanism for managing finances.

Loan

A loan is a sum of money borrowed from a financial institution or lender to be paid back with interest. Loans come in several forms, such as secured or unsecured, commercial, or personal.

Lum sump

A lump sum contract specifies a single overall price for an entire scope of work, even if multiple separate items have been quoted. Even though lump-sum payments are typically made all at once, lump-sum contracts can be broken down into . into separate installments.

Percentage of completion vs. Completed contract

Percentage of completion, also known as progress billing, will see invoices submitted at different stages of project completion; at specified time intervals (e.g., monthly) or when a milestone is hit, an invoice is submitted. Completed contract methods, on the other hand, will see a single invoice issued at the end of a project once it’s completed according to the contract.

Retention/Retainage

Retention & retainage mean the same thing; retainage is the amount of money (typically a percentage of each invoice) held back until the project is completed. Owners and GCs collect retainage as a way to ensure that the agreed upon scopes of work are completed to the standards of the contract.

Unit price contract

Unit pricing is a contract pricing method that assigns a value to each unit of a scope of work. For example, an asphalt contractor might specify that they receive $5 per square foot of asphalt laid.
