Construction contractors and remodelers have complex books. Learn how these bookkeeping tips can keep their finances accurate.

Running a successful home remodeling or contracting business requires more than just construction expertise. The financial foundation of your business depends on proper bookkeeping practices that can make the difference between thriving and merely surviving. Did you know that only 37.6% of construction businesses started in March 2011 survived a decade later? This stark reality underscores why mastering bookkeeping isn't optional—it's essential for long-term success.

Why Construction Bookkeeping Is Different

Unlike traditional businesses, construction and remodeling companies face unique financial challenges. Construction projects often span years, which adds a layer of complexity to construction bookkeeping. Contractors must carefully manage and account for the financial implications of ongoing projects, including the allocation of resources, tracking billable hours, and ensuring timely invoicing. Every project has different requirements, timelines, and profit margins, making accurate tracking crucial for business sustainability.

The decentralized nature of the industry makes construction bookkeeping so unique. No two projects are the same. It costs money just to move people and equipment to different sites. This complexity requires specialized knowledge and systems that traditional bookkeeping methods simply can't address effectively.

Essential Bookkeeping Tips for Contractors

1. Implement Project-Based Job Costing

Accurate job costing is essential for tracking each project's labor costs, materials, and overhead. By breaking down these costs, you can determine how much to charge and ensure that each project's profitability is clear. For successful contractors like Country Creek Builders, who specialize in basement finishing, tracking costs per square foot and material type is critical for maintaining healthy margins.

Create separate cost centers for:

  • Materials (lumber, concrete, fixtures)
  • Labor (hourly wages, subcontractor fees)
  • Equipment (rentals, fuel, maintenance)
  • Overhead allocation (insurance, permits, office expenses)

2. Separate Business and Personal Finances

To ensure accurate accounting, always keep your personal and business finances separate. This fundamental practice protects your business legally and simplifies tax preparation. Companies like Preferred 1 Concrete and Fredrickson Masonry maintain clear financial boundaries to ensure accurate profit reporting and tax compliance.

3. Choose Construction-Specific Accounting Software

QuickBooks, Sage 100 Contractor, and Procore are excellent choices for their comprehensive features tailored to construction accounting. Look for software that offers:

  • Job costing capabilities
  • Progress billing features
  • Subcontractor payment tracking
  • Equipment cost allocation
  • Integration with banking systems

4. Establish a Proper Chart of Accounts

Develop a well-organized chart of accounts tailored to the specific needs of your construction business. A thoughtful chart of accounts facilitates accurate categorization of transactions and enhances financial reporting. Your chart should include:

Revenue Categories:

  • Residential remodeling
  • Commercial construction
  • Specialty services (like Davis Contracting's basement finishing)
  • Change orders and extras

Expense Categories:

  • Direct materials by type
  • Subcontractor costs
  • Equipment and tool expenses
  • Insurance and bonding
  • Marketing and business development

5. Master Revenue Recognition Methods

Understanding when and how to record revenue is crucial for construction businesses. In construction accounting, the main options have traditionally included: the cash method, percentage of completion, and completed contract methods. Work with a qualified CPA to determine which method best fits your business model and ensures compliance with current accounting standards.

6. Implement Monthly Reconciliation Processes

Reconciling your business bank account with your bookkeeping records monthly is vital. This practice helps eliminate human errors and ensures your financial information is accurate and up-to-date. Without a monthly reconciliations system, you have no idea which transactions are real, and which aren't.

7. Track Subcontractor Payments Carefully

Construction companies often work with subcontractors, so managing these payments effectively is important. To maintain good working relationships and keep projects on track, ensure timely and accurate payment of subcontractor invoices. This is particularly important for specialty contractors like Legacy Painting and Christian Brothers, who often work as subcontractors themselves.

8. Maintain Detailed Bid and Project Cost Records

Accurate tracking of bidding processes and project costs is vital. This includes maintaining detailed records of bids, labor costs, materials, and other expenses related to each project. For companies like Moderno Construction Management, who handle multiple projects simultaneously, this detailed tracking enables better future bidding and profitability analysis.

Common Bookkeeping Pitfalls to Avoid

Duplicate Transactions

Duplicate transactions and transactions that never actually occurred are more common than you think, especially when you're using basic bookkeeping software. Implement proper approval processes and regular reconciliation to catch these errors early.

Mixing Personal and Business Expenses

This creates tax complications and makes it difficult to track true business profitability. Always maintain separate accounts and credit cards for business use.

Inadequate Documentation

Keep detailed records of all receipts, invoices, and contracts. Digital receipt management systems can help organize this information and make it easily accessible for tax preparation and audits.

Ignoring Cash Flow Management

Since many construction companies charge per project, pricing can vary in the same categories from one project to another due to market fluctuations. Plan for irregular cash flow patterns and maintain adequate reserves.
