EPC Accounting in Australia: Job-Cost Reporting From Month 1, Not Month 6

EPC accounting, done in Month 1 — not Month 6

Most EPC contractors discover the unbilled-variation problem too late. Approved variations sit in the gap between operations marking the work complete and finance sending the invoice. Three concurrent projects past, the gap compounds. We install job-cost reporting in Month 1 so the leakage is identified and recovered while it's still fresh.

Why the first 90 days usually pay for themselves

A representative engagement: $8M EPC contractor, mid-tier, switchboards and HV/LV installs. When we started, the founder was running cash forecasting on Sunday evenings in Excel. Three big projects from the prior FY had come in 12 percentage points under bid margin and nobody could say exactly why.

Month 1: clean chart of accounts, project tracking properly set up, first 13-week cash forecast.

Month 2: first proper job-cost report against the active register.

The job-cost report flagged something simple but expensive — three projects where approved variations had been delivered but never invoiced. Total: approximately $74,000. Recoverable in full. The job-cost report effectively paid for the engagement's first quarter in one finding.

This isn't a unique story. The unbilled-variations pattern shows up in most EPC engagements past three concurrent projects. It's why we install job-cost reporting in Month 1 — not Month 6.

The Finance Function for an EPC operator

• Job-cost reporting in Month 1. Active project register reconciled monthly. Bid value, variation register, dayworks not yet invoiced, retentions held. Margin reported monthly with variance-vs-bid commentary.

• Multi-project working capital model. Each project has a working capital draw. We model the aggregate working capital position 13 weeks out so you can see facility headroom or cash pressure coming.

• Daywork accrual discipline. Approved daywork at correct accrual, recognised when delivered (AASB 15) regardless of when invoiced. The single most common revenue leakage point.

Which tier is right for an EPC contractor

Most EPC engagements start at Financial Controller tier ($4,950/mo). The combination of multi-project tracking, AASB 15 timing discipline, bank facility narrative, and Power BI dashboard is what FC tier was designed for.

EPC contractors with revenue above $20M or those approaching an equity event move to Head of Finance ($8,500/mo).
