What is the percentage of completion method? The percentage of completion approach tracks revenue and expenses by measuring the amount of work completed relative to the total project scope.

Revenue recognition, the process of recording income when it's earned rather than when cash is received, is a critical challenge for construction companies, where projects often stretch over months or even years. The percentage of completion (POC) method offers a solution, allowing businesses to recognize revenue as a project progresses rather than waiting until it’s fully completed. It provides a clearer picture of cash flow and financial health at every stage of a project.

It also helps you track income and expenses more accurately while strengthening your ability to make informed decisions, secure funding, and maintain profitability throughout the project life cycle.

Just like enterprise accounting software, the POC method has many benefits for construction businesses. Read on to find out what those benefits are, how the POC method works, and how to incorporate it into your financial strategy to optimize performance.

Why the percentage method is important

The POC accounting method works on the principle that you should be able to track revenue in line with the project’s progress. It means that if 50% of a project is complete, you should be able to calculate 50% of the total expected revenue. As the project progresses and incurs more production costs, the percentage of completion increases, leading to a corresponding increase in recognized revenue.

Construction businesses can benefit greatly from the percentage of completion accounting method. Here are some of its benefits:

In essence, the POC method tracks progress in real time, which can produce even deeper insights when paired with a custom ERP system.

Enterprise resource planning (ERP) solutions make it easier to predict and avoid cost overruns by streamlining resource management, cash flows prediction, and project risks assessment. Its integrated reporting capabilities provide analytics that can also highlight trends, helping you make data-driven decisions to keep projects profitable and efficient.

The percentage of completion method adjustment

Initial estimates for costs and progress are often subject to change. The percentage of completion method adjustment addresses this by requiring companies to revise revenue recognition calculations when project costs or progress estimates are updated.

When project variables change, these adjustments help you:

As your project progresses and evolves, so should your projections.

Percentage of completion vs. completed contract method

The POC method recognizes revenue and associated expenses as work progresses, providing a continuous, real-time view of your financial health. So, if your project is 50% complete, you're only recognizing 50% of the expected revenue and costs.

In contrast, the completed contract method (CCM) defers the recognition of both revenue and expenses until the project is completed. While simpler, this method can obscure a company's financial performance during long-term projects, potentially leading to less accurate interim financial statements.

Choosing POC means aligning your financial reporting with actual project progress, offering a clearer picture of profitability and cash flow at every stage.

Percentage of completion calculation methods

There are several POC calculation methods available, each suited to different types of projects and scenarios. These methods help you determine the proportion of revenue to recognize based on the project's progress. Let’s explore the most common approaches.

Cost-to-cost method

The cost-to-cost method calculates the percentage of completion based on the ratio of costs incurred to date to the estimated total costs of the project.

Cost-to-cost method formula: (Costs incurred to date / Estimated total costs) * Total contract revenue

Let’s take an example to understand this better. If a project has incurred $500,000 in costs so far, and the estimated total cost is $1,000,000, with a total contract revenue of $1,200,000, the calculation would be:

(500,000 / 1,000,000) * 1,200,000 = $600,000

This type of clear, accurate financial reporting helps businesses present their financials to ownership in a synced and seamless way.

Efforts-expended method

The efforts-expended method is useful when costs alone are not a reliable indicator of project progress. It focuses on the actual effort expended, such as labor hours, machine hours, or materials used, to calculate the percentage of completion.

For example, if a project is expected to require 10,000 labor hours and 4,000 hours have been worked so far, the project would show as 40% complete in an ERP software like Intuit Enterprise Suite (IES).

This method is ideal for projects where labor or specific tasks are the primary drivers of progress, and it can provide a more accurate reflection of completion when cost data is not as precise.

Units-of-delivery method

The units-of-delivery method comes in handy for projects with distinct deliverables, such as construction phases or specific components of a larger project. Tracking progress is simple: Evaluating how many units you’ve finished relative to the total required units.

For instance, if a project involves the construction of 10 buildings, and six are completed, the project is 60% complete. Use this method when each unit or deliverable represents a significant portion of the project’s value.

Here are some real-world examples of how the percentage of completion accounting method is applied in different construction scenarios:

Producing the right POC method calculations is essential for accurate financial reporting. Ensure your accountants have reliable cost estimates and maintain open communication with project managers to assess project complexity.

Which companies should use the percentage of completion method?

The percentage of completion method is particularly suitable for companies involved in long-term projects with identifiable stages or milestones. This method is standard in industries such as:

Also, specific service industries, such as consulting or software development, may use the percentage of completion method for long-term projects with defined deliverables.

IRS requirements

The IRS mandates that construction companies use the POC method for long-term contracts that span beyond the end of the taxable year. Here are a few things you should know:

While the percentage of completion method is often required, certain smaller or shorter-term projects may still be eligible for the completed contract method, subject to IRS approval.

A tax professional can help you ensure compliance with IRS guidelines when using the percentage of completion method. Tax laws can be complex and may vary based on the project and business structure.

Common challenges with the percentage of completion method (and how to address them)

While the percentage of completion method offers significant advantages in terms of accurate revenue recognition, it also comes with certain risks that you should be aware of.

Inaccurate billing

Overestimating or underestimating project progress can lead to overbilling or underbilling customers. Overbilling can damage customer relationships and may result in legal consequences. Underbilling, on the other hand, can lead to lower business profitability and financial difficulties.

Your accounting team or solution should be able to:

From a supervision perspective, it’s also crucial to establish checks and balances to prevent the abuse of the percentage of completion method, ensuring that all progress claims are justified and accurately documented.

Change orders

Change orders can significantly impact a project's overall scope, cost, and timeline, negatively affecting financial performance. Mismanaged charge orders can lead to increased costs and delayed timelines, resulting in potential cash flow issues and budget overruns.

This can strain relationships with clients and stakeholders, as unanticipated changes may affect project delivery and satisfaction. Additionally, if revenue recognition is not adjusted accordingly, it can lead to inaccurate financial reporting, affecting the company’s profitability and decision-making processes.

Your accounting team or software should be able to:

These challenges are important to consider. Still, the percentage of completion method remains a powerful tool for accurately recognizing revenue. It provides a balanced approach to financial reporting by recognizing income as work progresses, ensuring that financial statements accurately reflect the project status at any given time.
