Construction Accounting vs. Regular Accounting

First things first, construction accounting and regular accounting are not the same. While most industries, such as retail or manufacturing, can use typical accounting principles, construction accounting is an entirely different ball game. Most other businesses offer fixed products or services from a fixed location at a fixed price. For example, a restaurant might sell a piece of cake for $10. But, unlike other industries,  construction businesses offer customized work in variable locations. Every job is different, which makes construction accounting… not a piece of cake. 

We’ll expand on the differences between construction accounting and regular accounting in the sections below. 


Construction companies primarily operate around projects, whereas other businesses have more stable and predictable profit centers. Each branch or division of the company makes an identifiable contribution to the company’s bottom line. For example, a restaurant might have multiple franchise locations. Each location is treated as a separate, standalone entity that is responsible for contributing to the company’s bottom line. 

Most construction projects are custom jobs with unique requirements and a variety of associated costs. Although two projects may have similar requirements, a number of factors including labor and equipment availability, working conditions, and more could result in entirely different costs. 

It can be helpful to view construction projects as individual profit centers. Although projects are constantly opening and closing and have unique requirements that change based on a number of factors, keeping project profits and losses separate will help you ensure that each of your jobs is profitable. 

The project-centered nature of the construction business means that construction companies need a different way to keep track of costs and expenses for each job. That’s where job costing comes into play! Job costing is a construction accounting practice that allows construction companies to track costs to particular projects. 

Field and Mobile Work 

Unlike other industries where work is done at a fixed location, businesses in the construction industry have to manage the accounting of operations that are constantly on-the-go. Equipment and labor is constantly moving from site to site to complete a variety of different jobs. This means that you have to consider mobilization costs such as travel time, insurance, and other related expenses for each job. It also means that you need to manage your inventory, equipment, and labor effectively so you ensure that you have the right tools to complete each job. 

Irregular Costs

The next accounting challenge construction companies face is ever-changing costs. Most businesses have fairly stable overhead costs. Fixed costs are pre-determined and variable costs are relatively easy to control. Construction businesses play more of a guessing game. You have to estimate your project timelines which will affect the costs of a project. 

It can also be difficult for construction companies to differentiate overhead costs from project costs. To solve this problem, it can be helpful to ask yourself, “would I still have these expenses if I didn’t have these contracts?” This will help you decide whether you need to allocate certain indirect costs to jobs so they are appropriately billed.  Indirect costs may still be necessary to a project’s completion but are often overlooked when attributing costs to certain jobs. 

Accounting Methods for Construction Companies 

Now that we’ve covered the differences between regular accounting and construction accounting, it’s time to dive in and discuss the different construction accounting methods. Certain revenue recognition methods may be more suitable for your business depending on your company size, annual revenue, and project lengths. 

Cash Basis

The cash method is the easiest and simplest accounting method that construction companies can use. However, it’s important to recognize that it can also provide the least accurate depiction of your financial health! This method involves recording revenue only once money is in the bank. Cost of goods sold and overhead costs are also only recorded when expenses are actually paid. This could leave you relatively in the dark in regards to the financial health of your business. You might not realize your business is in a financial hole until it’s too late. 

Although many small businesses prefer the cash method for its simplicity, only some contractors qualify. Those who do qualify generally yield lower taxes making it a desirable accounting option for tax purposes. Those with average annual revenues over the threshold for the cash method must choose one of the following accrual methods. 

Percentage of Completion 

Next up is the percentage of completion approach which is often considered the best accounting method for construction companies. This method provides a more accurate way for accountants to keep track of the expected gross profits and losses of each project. Contractors record income and expenses regularly throughout each project and revenue is only calculated for the portion of a project that has already been completed. 

This method gives contractors a better understanding of whether or not their projects will be profitable before a project is completed. Although this method is based on estimations, it generally provides relatively accurate financial data that can be used to better manage profit margins. 

In this method, it is critical to first implement cost-accounting methods to ensure that expenses are accurately recorded so the profits and losses of a given project can be accurately estimated. 

The percentage of completion method is often ideal for long-term contracts because tax calculations are made each year. This reduces your tax burden at the end of the project and protects you from the risk of tax fluctuations. On the other hand, if you prefer to defer your taxes, the next method may be a better option for you. 

Completed Contract Method 

The completed contract method involves reporting income only once a contract is completed in full, although payments may be received throughout the duration of a project. While this approach is often the most preferred method in the construction industry, it’s really best suited for short-term contracts under two years. 

Contractors will also use the completed contract method if it’s not possible to calculate the percentage of completion for a project or if they prefer deferring their taxes. By using this method, contractors can defer taxes until a project is completed. Keep in mind that using this method could increase your tax burden in the long run if tax laws are amended. Proceed with caution when using this method!

Construction Bookkeeping Tips 

In order for accountants to provide the necessary financial insights regarding your construction business, you need to be diligent with the day-to-day recording of your financial transactions. That is – your bookkeeping! Here are a few quick tips to help you simplify and improve your construction bookkeeping process:

  • Record all the information from your receipts and invoices with the help of an accounting software solution. This will save you time and eliminate manual errors. 
  • Keep a digital copy of your receipts and invoices on a cloud-based technology that will allow you to access these files anytime, anywhere.
