Austral Dynamics is a Sydney-based Microsoft Solutions Partner helping Australian businesses implement, migrate, and get real value from Microsoft Dynamics 365 Business Central, alongside CRM, Power Platform, and AI solutions including Microsoft Copilot and custom AI development. In this article, we look at how Business Central specifically supports construction and engineering businesses with project costing, progress billing, and compliance.
Construction and engineering businesses run on projects, not products — and that single difference is exactly where generic accounting software starts to break down. A job that runs for eighteen months, involves multiple subcontractors, progress claims, retentions, and variations, needs a financial system built around project cost control from day one, not a chart of accounts designed for a business that sells the same thing every month.
Why Standard Accounting Software Falls Short on Construction Jobs
Most off-the-shelf accounting platforms were built to answer a simple question: how much money came in and went out this month. Construction businesses need to answer a much harder one: how is this specific job tracking against its budget, right now, at this stage of completion. Without proper job costing, that question usually gets answered in a spreadsheet, updated manually, and out of date within days. Add subcontractor claims, retentions held against defects liability periods, and variations that change the scope and value of a job mid-stream, and a generic system simply doesn’t have the structure to keep up.
The result is familiar to most construction finance teams: profitability that’s only really understood after a job is finished, cash flow surprises when retentions or variations aren’t tracked properly, and hours spent each month reconciling project costs across spreadsheets, subcontractor invoices, and the accounting system.
How Business Central Supports Project-Based Construction Work
Dynamics 365 Business Central is built around exactly this kind of project complexity. Its job and project management functionality lets a business set up a detailed budget for each job — broken down by cost category, task, or work breakdown structure — and track actual costs against that budget in real time, not just at month-end.
Purchase orders, subcontractor invoices, timesheets, and material costs all flow into the same job costing structure, so a project manager or finance controller can see exactly how a job is tracking without waiting for a manual reconciliation. Because it’s a connected system rather than a collection of spreadsheets, cost overruns on a specific task or trade become visible early enough to actually do something about them, rather than showing up as a surprise at practical completion.
Progress Billing and Retentions, Handled Properly
Progress billing is one of the most operationally painful parts of construction finance when it’s managed manually — calculating percentage of completion, generating a compliant progress claim, tracking what’s been invoiced against what’s been earned, and holding the right retention amount until it’s due for release. Business Central supports milestone and percentage-of-completion billing structures natively, generating progress invoices that reconcile directly against the job’s budget and actual costs, rather than being calculated separately and re-entered.
Retentions can be tracked automatically against each progress claim, with visibility into what’s currently held, when it’s due for release, and against which job — removing one of the more common sources of cash flow leakage in construction businesses, where retention amounts are simply forgotten or released too early.
Managing Subcontractors and Variations
Most construction jobs involve multiple subcontractors, each with their own claims, payment terms, and compliance requirements. Business Central lets a business track subcontractor commitments against a job budget, so committed costs — not just costs already invoiced — are visible when assessing how much budget genuinely remains on a job. This matters enormously for cash flow and margin visibility, since a job can look profitable on paper right up until a wave of subcontractor invoices arrives that were always going to be owed.
Variations — extra work, scope changes, or client-requested amendments — can be tracked as distinct line items against the original job budget, keeping a clear record of what was originally quoted versus what’s been added, which matters both for margin visibility and for managing disputes over scope down the track.
Compliance and Reporting for Australian Construction Businesses
Australian construction businesses operate under specific compliance obligations — security of payment legislation, retention trust account requirements in some states, and industry-specific reporting for principal contractors. A properly configured Business Central environment can support the reporting structures these obligations require, rather than forcing a business to maintain compliance tracking entirely outside its core financial system.
Real-time job costing also supports better decision-making at the tender stage. Businesses with clean historical cost data on completed jobs are in a much stronger position to price new tenders accurately, rather than estimating based on incomplete or outdated cost history.
Frequently Asked Questions
1. What is Dynamics 365 Business Central and how does it help construction companies?
Dynamics 365 Business Central is Microsoft’s cloud ERP platform. For construction companies, it provides job costing, progress billing, subcontractor management, and financial reporting in one connected system, replacing manual spreadsheets and disconnected tools.
2. Can Business Central handle progress billing and retentions?
Yes. Business Central supports milestone and percentage-of-completion billing structures, generating progress claims that reconcile against job budgets, and can track retentions held and due for release against each job.
3. How does Business Central support job costing for construction projects?
Business Central allows businesses to set detailed budgets for each job, broken down by cost category or task, and tracks actual costs — including purchase orders, subcontractor invoices, and timesheets — against that budget in real time.
4. Can Business Central track subcontractor costs and commitments?
Business Central can track subcontractor commitments against a job budget, giving visibility into committed costs, not just costs already invoiced, which helps with accurate margin and cash flow visibility.
5. How does Business Central handle project variations?
Variations can be tracked as distinct line items against the original job budget, maintaining a clear record of scope changes and their financial impact separate from the original quoted work.
6. Is Business Central suitable for small and mid-sized construction businesses?
Business Central is designed for small and mid-sized businesses and can scale as a construction business takes on larger or more complex projects, without requiring a full system replacement.
7. Can Business Central help with construction compliance requirements?
Business Central can support the reporting and record-keeping structures needed for construction-specific compliance obligations, including retention tracking and progress claim documentation, though specific configuration should reflect each state’s requirements.
8. Does Business Central integrate with other construction management tools?
Business Central can integrate with other Microsoft applications and third-party construction management or estimating tools, allowing project and financial data to stay connected.
9. How does Business Central improve profitability tracking on construction jobs?
By tracking actual costs against budget in real time, rather than only after a job is complete, Business Central helps identify cost overruns early enough to address them, and provides better historical data for pricing future tenders.
10. Can Business Central manage multiple construction projects at once?
Business Central can manage multiple concurrent projects, each with its own budget, billing schedule, and cost tracking, while still providing a consolidated view of overall business performance.
11. How does Business Central help with cash flow management in construction?
By providing visibility into committed costs, progress billing status, and retentions held, Business Central helps construction businesses forecast cash flow more accurately than relying on invoiced amounts alone.
12. How long does a Business Central implementation take for a construction business?
Implementation timelines vary depending on business size and complexity, but a typical construction-focused implementation can range from several weeks to a few months, depending on the number of integrations and customisations required.

Getting Job Costing Right From the Start
The construction businesses that get the most value from Business Central are the ones that treat job costing as a core requirement from the outset, not an afterthought bolted on once other modules are live. Getting the cost structure, billing milestones, and retention tracking configured properly from day one avoids the common trap of a system that technically works but doesn’t reflect how a business runs its jobs.
If progress billing, subcontractor cost visibility, or job profitability tracking are ongoing headaches for your construction or engineering business, Austral Dynamics can walk you through what a purpose-fit Business Central setup would look like — get in touch to talk it through.
