By Rami Rajkumar, CPA · Founder & Partner, TechEdge Accounting · Updated 18 June 2026

TL;DR. The TechEdge Finance Office Content Library is the master cluster map across construction, solar, EPC, carbon-credit, and corporate finance. Three cornerstones (Construction Accounting Australia, Finance Function Maturity Playbook, Capital Structure Playbook) + ~45 cluster posts spanning AASB 15/16/123/138, GST treatment, EOFY tax planning, R&D incentive, ATO audit triggers, and CFO-level capital decisions — all referenced in one place.Key TakeawaysThree cornerstones anchor the three domains: project accounting, finance maturity, capital structure.Construction & civil cluster: WIP recon, job cost setup, retention/variation GST, P&L reading, RCTI, bank covenants.EPC/solar/renewables cluster: PSI vs PSB, R&D tax incentive, equipment finance vs lease, multi-project margin.Carbon-credit cluster: ACCU recognition timing (AASB 138), ANREU reconciliation, embodied carbon in D&C.Property/tax cluster: GST margin scheme + worked examples, 6-year CGT rule, trust distributions s100A, EOFY playbook.

This is a living map of TechEdge's content library. If you're an AU construction, solar, EPC or carbon-credit operator looking for practitioner-grade accounting guidance, start here. We organise everything by reader intent — what you're trying to figure out — rather than by topic taxonomy.

The library is built around five pillars, each with multiple cluster posts that drill into specific operational questions.

Pillar 1 — Construction & Civil Accounting (AASB 15)

The pillar for anyone running a construction or civil contracting business above $2M revenue. AASB 15 governs contract revenue recognition for long-duration projects. Get it right and your management accounts, bank narrative and tax position all align. Get it wrong and you're carrying material misstatement risk every quarter.
