ERP for Brisbane construction: a practical guide.

Brisbane’s construction sector is in the middle of an unprecedented pipeline. Cross River Rail, Queens Wharf, the Olympic 2032 infrastructure program, and a wave of residential and commercial developments across South East Queensland are creating more work than most builders have ever seen. The problem is that the systems most construction companies run on. Spreadsheets for job costing, email chains for variation approvals, manual progress claims, and disconnected accounting software. Were never designed for this volume. Job costing errors, missed variations, and progress claim delays cost real money, and the bigger the pipeline, the bigger the losses.

This guide covers what Brisbane construction companies need from an ERP implementation, which platforms are worth considering, and how to avoid the common mistakes that derail construction technology projects.

What Construction ERP Needs to Do

Construction is not retail, manufacturing, or professional services. The ERP requirements are fundamentally different, and any implementation that treats a builder like a generic business will fail. Here are the non-negotiable capabilities:

• Job costing with WIP tracking. Every dollar of labour, materials, plant hire, and subcontractor cost must be allocated to a specific job and cost code. Work-in-progress must be tracked in real time, not reconciled at month-end.
• Progress claims with retention. The monthly claim cycle. Preparing claims, tracking approvals, managing retention deductions, and reconciling payments. Must be automated rather than managed in spreadsheets.
• Variation management. Variations are where margin is made or lost. The system must track variations from request through approval to invoicing, with a complete audit trail.
• Subcontractor management. Most Brisbane builders rely heavily on subcontractors. The ERP must manage subcontractor contracts, track their progress claims, handle back-charges, and maintain compliance documentation including insurances and licences.
• Safety compliance documentation. Safe Work Australia and Queensland WHS requirements demand documented safety management. While a dedicated safety platform may handle the operational side, the ERP must integrate to ensure compliance records are linked to projects and subcontractors.

Which Platform Fits

Microsoft Dynamics 365 Business Central

The strongest option for mid-size Brisbane builders. Typically $10M to $200M in annual revenue. Business Central handles project-based accounting natively through its Jobs module, which maps well to construction job costing. Multi-entity support covers builders that operate through separate entities for different project types or joint ventures. The integration with Microsoft 365 means site managers can access project data from Teams on their phone, and the finance team works in a familiar environment.

For construction-specific requirements like progress claims and retention tracking, Business Central requires configuration and typically an ISV add-on such as VIZION or ExpandIT. These are mature solutions with strong Australian support.

SAP Business One

A solid choice for larger construction operations, particularly those with complex multi-entity structures or international operations. SAP Business One’s project management module handles job costing, budgeting, and WIP tracking. The platform scales well as businesses grow, though implementation costs and timelines are typically higher than Business Central.

Oracle NetSuite

Best suited for multi-entity construction groups that need cloud-native, real-time consolidation across multiple businesses. NetSuite’s SuiteProjects module provides project accounting and resource management. The platform’s strength is its flexibility for complex group structures, but it requires significant configuration for Australian construction-specific requirements.

Integration with Procore and Aconex

Many Brisbane builders already use Procore for project management or Aconex for document control. Your ERP must integrate with these platforms rather than replace them. The goal is a connected ecosystem where project data flows from the field (Procore) through document management (Aconex) into financials (ERP) without manual re-entry. Every manual handoff is an opportunity for error, delay, and cost leakage.

The Job Costing Problem

This is where most generic ERP implementations fail construction companies. Standard accounting software tracks income and expenses by account code. Construction needs to track them by job, cost code, and cost type. Simultaneously.

A single concrete pour involves labour (multiple trades at different rates), materials (concrete, rebar, formwork), plant hire (pump, crane), and subcontractor costs. All of these must be captured against the same job and stage, compared to the original estimate, and reflected in the WIP schedule. If any of these allocations are wrong, the job report is wrong, the progress claim is wrong, and the project margin is a fiction.

Purpose-configured ERP solves this by building the job costing structure into the chart of accounts and transaction entry workflow. When a purchase order is raised, the system requires a job number and cost code. When a timesheet is submitted, hours are allocated to specific jobs. When a subcontractor invoice arrives, it’s matched to the subcontract and allocated automatically. The result is a job cost report that the project manager can trust. Because the data entered the system correctly in the first place.

Progress Claims and Retention

The monthly progress claim cycle is one of the most time-consuming administrative tasks in construction. For a builder running ten active projects, each with twenty subcontractors, that’s two hundred subcontractor claims to process every month. Each with retention deductions, defects holdbacks, and payment schedules.

A properly configured ERP automates the claim cycle. Subcontractors submit claims against their contract value, the system calculates retention automatically based on the contract terms, project managers approve or adjust claims within the system, and approved amounts flow through to accounts payable. The retention register tracks every dollar held, the release conditions, and the defects liability period end date.

On the head contract side, the system generates the builder’s progress claim to the principal based on the percentage of work completed, adjusted for variations and contra charges. This claim links directly to the WIP schedule, so the finance team can see the relationship between costs incurred, revenue recognised, and amounts claimed.

Manual progress claim management using spreadsheets typically takes a senior administrator three to five days per month for a ten-project business. Automated claim management reduces this to less than a day.

Data Migration from Legacy Systems

Brisbane construction companies commonly run MYOB, Xero, or in some cases custom Microsoft Access databases that a former office manager built a decade ago. Migrating from these systems requires careful planning because construction data is inherently complex. Jobs have long lifespans, retention spans years, and historical cost data is needed for dispute resolution and final account negotiations.

A zero data loss approach means migrating not just current financial data, but historical job records, completed project archives, subcontractor payment histories, and retention balances. For businesses that have been operating for twenty years on MYOB, this can mean hundreds of thousands of transactions.

The migration process should include comprehensive data mapping, automated reconciliation at every stage, parallel running of old and new systems, and a tested rollback plan. For construction specifically, the WIP schedule must reconcile perfectly between the old and new systems at the point of cutover. If the WIP is wrong on day one, everything built on it. Progress claims, job reports, management accounts. Will be wrong too.

Getting It Right the First Time

Construction ERP implementations fail when they’re treated as generic accounting upgrades. The builder ends up with a system that produces a nice P&L but can’t tell the project manager whether a job is on budget, can’t generate a progress claim without a spreadsheet, and can’t track retention across fifty subcontractors.

The right approach starts with construction-specific discovery: understanding your job costing structure, claim cycles, subcontractor workflows, and reporting requirements before any platform is configured. The technology serves the workflow, not the other way around.
