Key takeaways

• Implement job costing software to track labour, materials, and overhead costs in real time, so you can spot budget overruns early and protect your profit margins before small issues become costly problems.
• Break every construction project into three distinct cost categories — labour, materials, and overheads — and build in buffer time and waste allowances to create estimates that reflect what jobs actually cost.
• Choose software that connects directly with your accounting platform and works on mobile devices, so your team can log time and expenses from the job site without entering data twice.
• Start with a small project when setting up job costing software, then use the reports to compare your estimates against actual costs and refine your process before rolling it out across your whole business.

What is job costing software?

Job costing software tracks all costs associated with a specific construction project, including labour, materials, and overheads. Instead of relying on spreadsheets, it automates calculations to show you a clear picture of each job's profitability.

This makes it easier and faster to estimate and track costs, so you can quote with confidence and spot budget issues early.

Benefits of job costing software for construction

Job costing software helps construction businesses protect profit margins and catch budget overruns before they become problems. Here are the key benefits:

• calculate accurate job prices: Work out specific costs for each project to create confident estimates and competitive quotes.
• reduce customer disputes: Estimate accurately upfront to prevent billing surprises and maintain client relationships.
• protect profit margins: Add markup and calculate margins automatically to stay competitive while staying profitable.
• track costs in real time: Monitor actual costs against estimates throughout the project to identify budget issues early.

Recent regulations like the 2023 Retention Money Amendment Act affect how project funds are handled, making accurate upfront estimates even more important. Real-time tracking is important for tax purposes on long-term projects that the ATO defines as straddling two or more income years. See the ATO's guidance on long-term construction contracts for details.

Key features of construction job costing software

Look for these key features when evaluating job costing software:

• track projects in one place: View all your time, costs, and progress for each job without switching between systems.
• access from anywhere: Log time and expenses from job sites using a mobile device, keeping data accurate and up to date.
• create invoices from tracked costs: Turn your recorded time and expenses into invoices without entering data again.
• run profit reports: See which jobs make money and which ones don't with clear, simple tools.
• estimate faster: Punch in the numbers and let the software do the maths, so you can submit quotes faster.

Breaking down construction job costs

Job costing separates construction projects into specific cost categories so you can create accurate estimates and track what you spend against them. Most construction jobs break down into three main cost centres:

Labour

Labour costs cover wages for direct employees and payments to subcontractors working on your project. To estimate labour accurately:

• calculate employee costs: Work out daily or hourly rates for your direct staff and multiply by expected project time.
• factor in subcontractor rates: Confirm availability and get written estimates, then verify with your own calculations.
• build in extra time: Add buffer time for unexpected tasks that typically arise during construction.

Materials

Material costs cover all physical items needed to complete your construction project, from primary building components to supporting supplies. When estimating materials:

• include direct materials: Calculate costs for wood, steel, electrical wiring, and other primary building components.
• add indirect materials: Factor in fasteners, caulking, and other supporting supplies.
• cover equipment hire: Include rental costs for tools and machinery you don't own.
• account for delivery and waste: Add extra to cover transportation costs and material losses.

Overheads

Overhead costs cover business expenses that support your projects but don't relate directly to specific construction tasks. Common overheads include:

• equipment wear and tear: Account for the loss of value on tools and machinery over time.
• office and admin costs: Include office rental, insurance, and general business costs.
• add a percentage to each job: Most builders add a fixed percentage to each job to cover overhead costs.

Work with an accountant to determine how to calculate overheads for your business. Tax law requires appropriate adjustments to standard accounting methods for income tax purposes.

Choosing the right job costing software

When choosing job costing software for your construction business, consider:

• your team size: Do you need to track time for a large crew or just a few people?
• subcontractor management: Are you managing multiple subcontractors who need access?
• ease of use: Will everyone on your team actually use it, or is it too complicated?
• connection with other tools: Does it connect with your accounting platform and other tools you rely on?
• mobile access: Can your team log time and costs from job sites?

Understanding job costing software costs

Job costing software pricing varies depending on the provider and features included. Most solutions use one of these pricing models:

• included with accounting software: Some platforms like Xero include project tracking and job costing features as part of your subscription.
• per-user pricing: Standalone tools often charge a monthly fee for each user who needs access.
• tiered plans: Many providers offer different feature levels at different price points.

When comparing costs, factor in the time you'll save by not tracking manually and the money you'll protect by catching budget overruns early. The right software should pay for itself through better project visibility and fewer costly surprises.

How to set up job costing software for construction

Setting up job costing software takes a bit of upfront work, but it pays off with better insight into and control over your projects. Here's how to get started:

1. Choose your software: Find a tool that connects with your accounting software so your financial data stays linked and accurate.
2. Define your cost codes: Set up categories for labour, materials, and subcontractors so you can track spending by type and compare costs across jobs.
3. Create your first project: Start with a small job to get comfortable entering time and expenses before rolling it out across your business.
4. Review and adjust: Use the software's reports to compare your estimates against actual costs, then refine your process for the next job.
