Top-notch construction accounting practices are just as important to a successful construction business as materials, labor, and equipment. Unfortunately, many construction companies, especially smaller ones, struggle to get a clear picture of their revenues, expenses, and profits.

This guide provides a comprehensive overview of construction accounting, covering key concepts and strategies that can help you streamline your financial processes and make informed decisions.

What is construction accounting?

Construction accounting is a specialized branch of accounting that focuses on financial management and reporting for construction projects. Like other forms of accounting, it includes tracking and analyzing costs, managing budgets, monitoring cash flow, and ensuring compliance with industry regulations. At its best, construction accounting provides valuable insights for decision-making and fuels healthy financial growth.

Construction accounting vs regular accounting

Construction accounting vs regular accounting: What’s the difference?

Regular accounting encompasses the general financial management tasks and reporting that are required by any business. Construction accounting methods build on that foundation, adding specialized practices to address the unique nature of construction projects. It's more focused than regular accounting and requires more technical knowledge.

Construction accounting tracks the costs related to materials, labor, and equipment, as well as managing project budgets and cash flow. It also involves identifying payment terms in construction contracts, complying with industry regulations, and managing project-specific financial risks.

The following section digs into these areas in more depth, highlighting some of the unique challenges that construction accountants may face.

Construction accounting vs financial accounting

From accurate job costing and job pricing to complex accounting methods, construction company accountants face several unique challenges. Let's take a closer look at some of these construction accounting issues.

Top construction accounting issues

Top construction accounting issues

Job costing: All companies need to anticipate future expenses, but job costing in the construction industry poses some unusual difficulties. Over the course of a multi-year contract, even the cost of materials can change significantly between the time work begins and the day it's completed. Job costs can also be affected by changes in regulations, unusually inclement weather, pre-existing contamination discovered at a dig site, and other unforeseen events. 

Job pricing: The approach to job pricing is simple enough—determine your expected costs and then add a certain percentage to account for risk and profit. But that's easier said than done in the construction business. Add too much for risk, and you could easily be outbid on contracts. Add too little, and the company could end up in the red. Insurance can help mitigate some of these risks, but making sure policies meet both financial and regulatory requirements can be a challenge in itself.

Managing job site budgets: Once a contract is in place, it's vital to oversee job site budgets to make sure a wide range of actual costs meet expected costs on each individual project and construction job. These include material costs, equipment costs, labor costs (including hours and rates), and more. Keeping accurate records is critical for construction firms, especially given the complexities of construction accrual methods like the percentage of completion method.

Long-term contracts: Contracts that span multiple accounting periods are common in the construction industry. In fact, many construction contracts take years to complete, and expenses often hit a company's cash flow long before payment comes in the door. This creates challenges in overseeing cash flow, managing credit, and matching revenue with expenses to generate meaningful income statements.

Progress billing: Many construction contracts build progress billing into their long-term contracts to help lower their risk and even out their cash flow. Payments are due at certain milestones along the way, but expenses may already be accumulating toward later milestones. When this is happening across multiple job sites, matching expenses to revenue can be especially tough.

Subcontractor payments: Before a subcontractor's invoice can be paid, the contractor's accounting team needs to verify that the amount is justified. This means checking each invoice against its underlying contract, identifying the correct job site, and verifying with the project manager (often by remote communication) that the invoiced work has been completed, inspected, and approved. 

Unforeseen circumstances: Change orders, permitting problems, environmental protection issues, and even bad weather can wreak havoc on job costing, timelines, and construction budgets. Construction accountants often need to revise budget projections mid-project to help corporate leadership navigate costly setbacks.

Standards and regulations: Due to the long timelines and considerable risks of construction projects, construction accountants need to adhere to specific standards and regulations that affect their accounting methods and tax reporting. This also affects the particular accounting methods that construction firms are required to use.

Construction accounting best practices

8 construction accounting best practices

1. Use specialized accounting tools

Construction accounting involves complex processes, such as job costing, progress billing, and contract management. To streamline these tasks and help ensure accuracy, invest in construction accounting software and financial automation tools that are designed for the industry.

2. Implement a cost-coding system

A cost-coding system is essential for tracking construction project expenses such as labor, materials, subcontractors, and equipment. Assigning unique codes to each cost category can provide more visibility into your cost structure and help you generate accurate financial statements.

3. Reconcile accounts regularly

Compare your account records with bank statements regularly to ensure accuracy and identify any discrepancies. Regular reconciliation can help you catch errors, prevent fraud, and maintain the integrity of your records and financial statements.

4. Track construction project costs in real time

Construction expenses need to be monitored closely to keep your projects on budget. Implement a system to track and manage costs in real time, including labor, materials, equipment rentals, and subcontractor expenses. 

5. Prepare accurate and timely progress billings

Progress billing is a common practice in the construction industry—structuring payments based on the completion of specific project milestones. Implement systems that help you stay on top of the progress of each job. This will ensure that progress billings are prepared accurately and submitted on time to maintain a steady cash flow.

6. Maintain detailed records and documentation

Construction projects involve a large number of documents, including contracts, change orders, invoices, and receipts. Be sure to maintain detailed records and documentation that can support your financial transactions and provide evidence in case of disputes or audits.

7. Review financial reports

Regularly review financial records and reports, such as profit and loss statements, balance sheets, and cash flow statements. This can help you identify cost trends, assess project profitability, and make informed choices to optimize your construction operations.

8. Stay up to date on industry accounting standards and regulations

Construction accounting practices and regulations tend to evolve over time. Stay updated on industry changes by attending seminars, joining professional associations, and subscribing to industry publications. This will help you make sure you're always following the latest best practices and complying with regulatory requirements.

FAQ

What does a construction accountant do?

A construction accountant does what other accountants do, applying generally accepted accounting principles (GAAP) to construction businesses. They simply face unique challenges, standards, and regulations. They allocate direct and indirect costs, invoice customers, apply overhead costs, manage job costing and pricing, prepare expense reports, handle payroll management, and much more, helping construction business owners make complex financial decisions. They also prepare important financial statements such as annual revenue reports, profit and loss statements, and so on.

How to account for construction

Whether your company uses a cash method or accrual method of accounting, understanding your actual costs begins with accurate accounting, excellent document management, and a solid grasp of basic accounting principles, such as revenue recognition. To account for numerous complex projects across scattered job sites, cloud-based software for both accounting and financial automation are highly recommended.

What are the different construction accounting methods?

There are many construction accounting methods representing different contract revenue recognition methods. The right method of accounting for a given company depends on the size of the company and the length of its contracts—they can't all be used by every construction firm for every job.

  • The cash method, or cash-basis accounting method
  • The completed-contract method
  • The percentage-of-completion method
  • The ASC 606 standards method

Is construction accounting hard?

Construction accountants need to maintain accurate bookkeeping for multiple business expense categories across multiple job sites and often multiple bank accounts. They also need a basic understanding of construction project management and the ability to communicate easily with construction managers about project progress.

These accountants need solid skills in both mathematics and communication, as well as excellent time management skills.

BILL Spend & Expense
Best for AI expense automation
4.5 on G2
  • Smart corporate cards with real-time tracking, flexible limits, and instant visibility into every transaction across your team [1]
  • Unlimited free virtual cards with unique numbers for each vendor or subscription—freeze, delete, or set custom limits instantly to prevent overcharges and reduce fraud risk [5]
  • AI-powered auto-categorization and receipt matching that connects card transactions and expenses into a single reconciliation workflow [1]
  • Customizable budgets with spend controls based on merchant, amount, receipt requirements, and configurable approval workflows [3]
  • Auto-freeze on cards with incomplete transactions, ensuring receipts and documentation are captured before additional spend is approved [1]
  • Up to 7x points on restaurants, 5x on hotels, 2x on recurring software, and 1.5x on all other purchases (rates shown are for weekly or daily billing cycle; rates vary by billing frequency) [2]
  • Two-way sync with QuickBooks, NetSuite, Sage Intacct, Xero, and Microsoft Dynamics; additional integrations with Acumatica, Slack, and HRIS platforms [1]

Pros

  • $0/user/month with all features included—no paid tier to unlock [4]
  • Merchant controls and auto-freeze cards at no extra cost [1]
  • Credit lines that don't fluctuate daily based on bank balance [4]
  • All ERP integrations (NetSuite, Sage Intacct, Xero) included free [1]

Cons

  • 12-month holding period before rewards can be redeemed [2]
  • Category reward multipliers cap at $5,000/month per category [2]
  • Less established in global, enterprise-scale expense programs with multi-country regulatory requirements

BILL Spend & Expense pairs corporate cards with AI-powered expense management and budget controls in a single platform at no cost—teams aren't paying per user or upgrading to unlock features that competitors gate behind paid tiers.

Merchant-level spend controls and auto-freeze on incomplete transactions give admins granular oversight without manual policing, and two-way ERP integrations are included free where Ramp and Brex charge for NetSuite and Sage Intacct access. The main trade-off is an initial 12-month rewards holding period before accumulated points can be redeemed. [1][2][3][4]

Commonly compared to: Ramp and Brex (for card-first expense management), and SAP Concur (for enterprise expense programs).

Pricing
$0/user/month with no annual fee
Integrations
Two-way sync with QuickBooks, NetSuite, Sage Intacct, Xero, and Microsoft
Ideal company size
SMB to mid-market
SAP Concur
Best for large enterprises
4 on G2
  • AI-powered receipt capture via ExpenseIt on the SAP Concur mobile app, with smart matching that combines credit card charges and e-receipts into expense reports automatically [7]
  • Configurable approval workflows with built-in audit rules that flag policy exceptions, plus optional Intelligent Audit and Verify add-ons for automated compliance checks [6][7]
  • Modular product suite: Concur Expense, Concur Travel, and Concur Invoice are separate products that can be purchased individually or together, so organizations can start with expense management and add capabilities over time [6]
  • Bank card feed integrations that import corporate card transactions directly into expense reports for automatic reconciliation [6]
  • Joule, SAP's AI assistant, for expense report review, spend analysis, and cost estimation [6]
  • Budget tracking and monitoring tools that give finance teams visibility into spend against departmental or project-level budgets [6]
  • Support for global operations with multi-currency expense reporting and country-specific tax and regulatory compliance tools [6]
  • Pro: 300+ pre-built integrations including native SAP ERP sync [7][8]
  • Pro: Global coverage with multi-currency and regulatory compliance tools [6]
  • Pro: Modular—add travel or invoice management without switching platforms [6]
  • Pro: AI-powered receipt capture and smart matching via ExpenseIt [7]
  • Con: Quote-based pricing; no published rates on the website [6]
  • Con: No corporate card offering; relies on bank card feed integrations [6]
  • Con: Implementation can be complex for smaller organizations [6]
  • Con: Live support requires purchasing the User Support Desk service [6]

SAP Concur is the incumbent in expense management software, with the largest partner ecosystem and broadest global footprint on this list. Its modular approach gives large organizations flexibility to start with expense management and layer on travel or invoice capabilities independently.

The trade-off is complexity—pricing is opaque, there's no corporate card offering, and smaller teams may find the platform more than they need. Organizations already in the SAP ecosystem will get the most value from native S/4HANA integration. [6][7][8]

Commonly compared to: BILL (for SMB expense management), and Coupa (for enterprise spend management).

Pricing
Quote-based
Integrations
QuickBooks, Xero, Sage,TSheets, Gusto, & most business credit cards.
Ideal Company Size
Mid-market to enterprise
Ramp
Best for a broad spend platform
4.8 on G2
  • Corporate cards with customizable spend controls by merchant, category, employee, or department, plus unlimited virtual and physical cards [9][10]
  • AI-powered receipt matching, transaction coding, and memo suggestions that auto-populate as soon as a card is swiped [9]
  • Policy agent that reviews every expense against company policy, auto-approves compliant transactions, and escalates only exceptions with full audit trail [9]
  • Expense submission via SMS, Slack, or Microsoft Teams in addition to web and mobile app [9]
  • Reimbursements for out-of-pocket expenses paid to employees' bank accounts in 1–2 business days [9]
  • Real-time spend reporting with custom dashboards, natural-language queries, and proactive overspend alerts [9]
  • Broader spend platform that includes AP automation, procurement, vendor management, and treasury alongside expense management [9]

Pros

  • Free plan includes corporate cards, expenses, and bill pay [11]
  • AI policy agent reviews 100% of expenses automatically [9]
  • Submit expenses via SMS, Slack, or Teams—no app required [9]
  • Broader spend platform covers AP, procurement, and vendor management [9]

Cons

  • Budget tracking requires Ramp Plus at $15/user/month [11]
  • NetSuite, Sage Intacct, and Dynamics integrations require a paid plan [11]
  • HRIS syncs and auto-lock cards require a paid plan [11]
  • Credit limits fluctuate daily based on connected bank balance [12]

Ramp's strength is breadth—it's not just an expense tool but a full spend management platform that includes AP automation, procurement, and vendor management alongside expenses. The AI policy agent is a differentiator, reviewing every transaction against company rules rather than relying on manual manager approvals.

The trade-off is that several features mid-market teams rely on—budget tracking, ERP integrations beyond QuickBooks and Xero, and HRIS syncs—require upgrading to Ramp Plus at $15/user/month plus a platform fee. [9][11]

Commonly compared to: Brex and BILL (for corporate cards and expense management), and SAP Concur (for enterprise expense programs).

Pricing
$0/user/month
Integrations
QuickBooks, NetSuite, Xero, Sage Intacct, Slack, & 100+ accounting tools.
Ideal Company Size

Brex
Best for global teams
4.8 on G2
  • Corporate cards with customizable spend limits by role, department, or category, plus auto-approve for in-policy expenses and auto-decline for out-of-policy spend [13][14]
  • AI-powered expense reviews that auto-approve compliant transactions and surface only exceptions for human review, with clear visibility into why a transaction is flagged [13]
  • Auto-generated receipts and memos with OCR that matches receipts in any language or currency, plus automatic GL coding by department, project, and entity [13]
  • Live Budgets that let department heads set top-level budgets, provision spend to individuals or teams, and track usage in real time with anomaly detection [13]
  • Global reimbursements in 70+ countries in employees' local currency, with subsidiaries able to issue reimbursements from local bank accounts [13]
  • Expense submission and approval via Slack and WhatsApp, with in-app commenting on individual transactions [13]
  • Broader financial platform that includes bill pay, business banking with up to 3.68% yield, and treasury alongside expense management [14]

Pros

  • Free plan includes corporate cards, expenses, bill pay, and travel [15]
  • AI expense reviews with 99% average policy compliance rate [14]
  • Global reimbursements in 70+ countries in local currency [13]
  • Live Budgets with real-time tracking and anomaly detection [13]

Cons

  • Live Budgets require Premium at $12/user/month [15]
  • HRIS syncs and customizable ERP integrations require a paid plan [15]
  • Credit limits fluctuate daily based on connected bank balance [16]
  • Multiple expense policies and dynamic review chains require Premium [15]

Brex positions itself as a full financial stack for startups—cards, expenses, banking, and treasury in one platform. The AI expense reviews and 99% average compliance rate (per Brex's internal metrics) are notable, and the global reimbursement coverage across 70+ countries is broader than most competitors on this list.

Like Ramp, Brex gates budget management and HRIS integrations behind a paid tier, and credit limits fluctuate daily based on your bank balance. Teams that need predictable spending power or are past the startup stage may find the pricing structure adds up. [13][14][15]

Commonly compared to: Ramp and BILL (for corporate cards and expense management), and SAP Concur (for enterprise expense programs).

Expensify
Best for simple reimbursements
4.5 on G2
  • SmartScan receipt capture by photo, email forwarding (receipts@expensify.com), or text message; auto-extracts transaction details and categorizes expenses [17]
  • Bring-your-own-card support: link existing corporate cards from 10,000+ banks globally for automatic reconciliation without switching card providers [17]
  • Expensify Visa Commercial Card with cash back on US purchases; cash back first offsets the Expensify subscription cost, then flows to the company's bank account [17]
  • Concierge AI for automated expense categorization, policy violation flagging, rule enforcement, and error reduction [17]
  • Global reimbursements for employees and independent contractors in their local currency [17]
  • Chat-based collaboration directly on individual expenses to resolve questions in real time rather than through email follow-ups [17]
  • 45+ integrations including QuickBooks, NetSuite, Sage Intacct, Xero, Workday, and Gusto [17]

Pros

  • Bring-your-own-card from 10,000+ banks globally [17]
  • Expensify Card cash back can offset the subscription cost [17]
  • SmartScan receipt capture by photo, email, or text message [17]
  • 45+ integrations including major ERPs and payroll systems [17]

Cons

  • No free plan; starts at $5/user/month [18]
  • Pricing structure varies by card spend volume [18]
  • Budget management, advanced approvals, and expense policies require Collect or Control plans [17]
  • No department-level budget management on par with card-first platforms

Expensify's strength is accessibility—it has the lowest barrier to entry for teams that just need to start tracking expenses and submitting receipts. The bring-your-own-card support from 10,000+ banks means companies don't have to switch card providers, and the SmartScan receipt capture (by photo, email, or text) is one of the more flexible input methods on this list.

The trade-off is that several features mid-market teams expect—budget management, advanced approvals, and expense policies—require upgrading to the Collect or Control plans, and spend controls are primarily limited to the Expensify Card rather than extending across all connected cards. [17][18]

Commonly compared to: Zoho Expense (for budget-friendly expense management), and BILL and Ramp (for integrated cards and expenses).

Pricing

Integrations
QuickBooks, Xero, Sage, TSheets, Gusto, & most business credit cards.

Zoho Expense
Best for budget-conscious teams
4.5 on G2
  • Autoscan receipt capture with OCR that auto-categorizes and itemizes each expense, plus the ability to split or tag expenses across departments, projects, or cost centers [19][20]
  • Automated per diem calculations with pre-defined rules based on country, location, and trip details for regional compliance [20]
  • Corporate card management with real-time feeds that automatically match transactions to uploaded receipts for faster reconciliation [20]
  • Mileage tracking with four input methods across Android, iPhone, and Apple Watch [20]
  • Configurable approval workflows, expense policies, and audit rules with detailed audit trails for compliance [19][20]
  • Custom modules, workflow automation, webhooks, and configurable UI elements for businesses that need tailored expense processes [19]
  • Active-user pricing model: only employees who actually create expenses are charged, so admins and approvers who don't submit reports are free [21]

Pros

  • Free plan available for up to 3 users with core expense tracking [21]
  • Active-user pricing—admins and approvers aren't charged [21]
  • Automated per diem calculations by country and location [20]
  • Deep customization with custom modules and workflow automation [19]

Cons

  • Corporate card feeds and multi-level approvals require Standard plan [21]
  • Deepest value requires the broader Zoho ecosystem (Books, People, CRM) [19]
  • No corporate card offering; relies on connecting existing cards [20]
  • Travel booking, per diem, and live budgets require Premium plan [21]

Zoho Expense offers unusually deep customization at a low price point—custom modules, workflow automation, webhooks, and configurable UI elements that most competitors don't expose. The active-user pricing model is genuinely cost-effective for companies where only a portion of employees submit expenses regularly.

The trade-off is that there's no corporate card offering—you'll need to connect your existing cards—and the platform delivers its deepest value when used alongside other Zoho products like Zoho Books and Zoho People. [19][20][21]

Commonly compared to: Expensify (for budget-friendly expense management), and SAP Concur (for global compliance and customization).
