Microsoft Business Central is Microsoft's cloud ERP platform for small and mid-sized businesses — used by Australian construction companies to manage project costing, subcontractor compliance, financial reporting, and supply chain management within the same Microsoft 365 ecosystem as their email, Teams, and SharePoint. Mycelium 365 provides Business Central implementation and advisory services for Australian construction companies, including AI and Copilot integration for project administration.
Why are Australian construction companies moving to Business Central?
Australian construction companies are moving from MYOB, Xero, and legacy job costing software to Business Central for three reasons — integration with Microsoft 365 (emails, documents, Teams conversations and financial data in one system), project-specific modules (job costing, subcontractor management, progress billing, retention tracking), and the AI layer through Microsoft Copilot for Business Central.
Business Central replaces the common pattern of MYOB for accounting, a separate job costing spreadsheet, and SharePoint for documents — consolidating into a single system that reduces data re-entry and provides real-time project profitability visibility rather than month-end guesses.
Master Builders Australia found that 68% of Australian construction businesses are planning ERP or job management system upgrades in 2026, driven by margin pressure, cash flow visibility requirements, and the shift to cloud-first tooling across the sector.
What Business Central modules matter most for construction?
The five modules that carry the most weight for a construction business:
- Jobs and project management — job costing, budgets vs actuals, progress billing, and WIP (work in progress) reporting.
- Subcontractor management — purchase orders, subcontract variations, retention tracking, and payment scheduling aligned to milestones.
- Fixed assets — plant and equipment register, depreciation, maintenance scheduling.
- Financial management — multi-company consolidation, progress claim processing, and BAS/GST reporting configured for Australian compliance.
- Document management — integration with SharePoint for contract storage, variation orders, and RFI management directly from Business Central records.
Together these cover the day-to-day construction back office without the spreadsheets, shared inboxes, and reconciliation work that tie up an admin team in a typical mid-sized builder.

Microsoft Copilot in Business Central — what can it do for a construction company?
Microsoft Copilot for Business Central is generally available in Australia as of 2026, and the four most valuable use cases for construction are:
- Drafting subcontract variations and progress claim letters from job record data — Copilot writes the letter using the actual variation values, dates, and contract references, ready for the PM to review.
- Summarising project financial performance from the job ledger in plain English for a site manager or director who does not read formal financial reports.
- Generating purchase order descriptions and item catalogues from photos or written specifications using AI vision — useful for one-off site purchases and new supplier onboarding.
- Predicting cash flow variance by analysing historical payment patterns from subcontractors and clients, flagging jobs likely to breach forecast.
Each of these removes hours of manual administration a week for project admin teams that are typically stretched.
How does Business Central integrate with Microsoft 365 for construction?
Business Central integrates deeply with Microsoft 365 in ways that matter for construction:
- Outlook integration — emails linked to job records; subcontractor correspondence tracked against purchase orders.
- Teams integration — job status updates posted to project Teams channels; approvals handled directly in Teams.
- SharePoint integration — contract documents, variations, and RFIs stored in SharePoint linked to Business Central job records.
- Power Automate integration — automated subcontractor compliance workflows, purchase order approval flows, and progress claim notifications.
The integration eliminates the common construction company problem of financial data in MYOB, documents in SharePoint, communications in email, and project updates in a separate system — all disconnected. See our modern workplace service and managed AI automation for the Power Automate and Copilot side.
Business Central implementation for Australian construction companies — what to expect
A Business Central implementation for a 20–100 user Australian construction business typically takes 8–16 weeks — discovery and design, data migration from MYOB or Xero (charts of accounts, open jobs, subcontractors, fixed assets), configuration of construction-specific modules, integration with SharePoint and Teams, user acceptance testing, and cutover.
Training is a critical success factor — site managers and project administrators need role-specific enablement, not generic Business Central training. Mycelium 365's Business Central implementation advisory is delivered by senior consultants with construction sector experience, working alongside your finance lead and project team.

Why Australian construction companies choose Dynamics 365 Business Central
Australian builders, civil contractors, and fit-out firms usually reach the limits of general accounting software at the same point: when the number of concurrent jobs, subcontractors, and progress claims outgrows spreadsheets. Dynamics 365 Business Central is an ERP built around job costing and project-based accounting, so every cost — labour, materials, plant hire, subcontractor invoices, and variations — is posted against the job rather than reconciled after the fact.
Job costing in Business Central tracks budget versus committed versus actual cost at task level, which means a project manager can see cost-to-complete during the job rather than at practical completion. Purchase orders are raised against a job and task, so committed cost is visible the moment an order is placed. Subcontractor management ties supplier records, retention terms, insurance expiry, and payment schedules to the contract, so payment runs do not release money to a subcontractor whose certificate of currency has lapsed.
Because Business Central is part of the Microsoft stack, it integrates natively with Microsoft 365. Approvals arrive in Outlook and Teams, job reports open in Excel with live data, documents live in SharePoint against the project, and Power BI dashboards report WIP, margin, and cash flow to directors without manual consolidation. For construction businesses already standardised on Microsoft 365, this removes an entire layer of integration and licensing overhead.
Business Central for construction vs MYOB and Xero
MYOB and Xero are strong general ledgers. They are not ERP systems, and the gap shows most sharply in construction.
Job costing depth. Xero and MYOB support tracking categories and basic project modules, which work well for simple, short jobs. Business Central provides multi-level job and task structures, job budgets, WIP calculation methods, and cost-to-complete reporting on every line — the level of detail required for multi-stage contracts running across financial periods.
Progress billing. Progress claims, schedules of value, and retention are first-class concepts in Business Central. In MYOB or Xero, progress claims are typically managed in spreadsheets and re-keyed as invoices, which is where reconciliation errors and disputed claims begin.
Contract management. Business Central holds contract values, approved variations, and forecast final cost against the job, so the reported contract position matches what the site team believes it to be. General accounting packages have no native concept of an approved variation.
Purchase orders against jobs. Committed cost is the number that determines whether a job is going to lose money. Business Central captures it at purchase order level per job and task; MYOB and Xero surface it only once a supplier invoice is entered, usually weeks later.
The practical test is simple: if directors cannot answer "what is the forecast final margin on this job today?" without a spreadsheet, the accounting platform has been outgrown.
How Mycelium 365 implements Business Central for Australian construction companies
Our implementations follow a fixed-price, four-stage approach designed around construction operations rather than generic finance.
Scoping. We run a workshop with the finance lead and project team to define the chart of accounts, job and task structure, WIP method, retention terms, subcontractor workflow, and the integration points with estimating software, project management platforms, and payroll. The output is a documented design and a fixed price.
Data migration. We migrate opening balances, customers and suppliers, job history, outstanding purchase orders, and retention balances from MYOB, Xero, or the incumbent ERP, with a reconciliation pack signed off before go-live.
Integration. Business Central is connected to Microsoft 365 — SharePoint for job documentation, Teams for approvals, Outlook for supplier correspondence, Power BI for reporting — and to construction-specific tools such as Procore or Aconex via API and Power Platform connectors.
Go-live and support. We train finance, project management, and administration staff, go live at the start of a financial period to simplify reconciliation, and provide 90-day hypercare followed by ongoing managed support.
Business Central construction features — what Australian builders and contractors need
- Progress claim management — schedules of value, claim certification, and invoicing aligned to the contract, with claimed-to-date and remaining value visible per job.
- Retention tracking — retention withheld and released tracked per contract and subcontractor, with defect liability period dates recorded so releases are not missed or paid early.
- Variation management — pending, approved, and rejected variations tracked against the contract value, so forecast final cost reflects approved scope.
- Subcontractor certificates of currency — insurance, licence, and compliance document expiry recorded against the supplier, with alerts before payment runs.
- WHS documentation management — SWMS, inductions, and safety documentation stored in SharePoint against the job and surfaced in Business Central through document links.
- Integration with Procore or Aconex — project, cost, and document synchronisation so site teams and finance work from one set of numbers.
How much does Business Central cost for Australian construction companies?
Dynamics 365 Business Central Essentials is approximately $84 AUD/user/month and covers finance, job costing, purchasing, sales, and project management — sufficient for most builders and contractors. Business Central Premium is approximately $119 AUD/user/month and adds service management and manufacturing, relevant to contractors running fabrication or maintenance divisions. Team Member licences are available at a lower rate for staff who only need to view data or enter timesheets.
Implementation is the larger investment. For an Australian construction company, a Business Central implementation typically ranges from $40,000 to $120,000 depending on the number of entities, integration complexity, and data migration scope. Mycelium 365 quotes implementation fixed-price after scoping, so the number does not move mid-project.
Ongoing managed support from Mycelium 365 starts from $95/user/month, covering Business Central administration, Microsoft 365 management, helpdesk, and cyber security under one agreement. Talk to us for a scoped proposal.
